Can self-leveling cement be used directly as a floor?

The LCD on the body of the small laser leveler also needs to be cleaned. You can use organic resin or lens cleaning cloth to wipe off the dirt. If there is too much dirt, it can be removed with a lens cleaning solution. The small laser leveling machine is a kind of equipment that takes the laser as the reference plane, adopts the original imported receiving and sending system, and controls the leveling head in real time to achieve high-precision and fast leveling of concrete. The leveling machine has a certain understanding, so how to maintain the small laser leveling machine after normal use? The small laser leveling machine manufacturer will explain to you how to maintain the small laser leveling machine after use. 1. The LCD on the body of the small laser leveler also needs to be cleaned. You can use organic resin or lens cleaning cloth to wipe off the dirt. If there is too much dirt, it can be removed with a lens cleaning solution. 2. There will be a lot of dust and mud on the small laser leveling machine after construction. First, wipe off the dust on the small laser leveling machine, and wipe off the dirt and oil stains with tissue paper or cotton cloth. 3. If the laser signal is lost during the construction of the small laser leveling machine, the machine needs to be restarted, and the interval should be more than ten seconds. 4. If there are too many stains, you can use a soft cloth to soak in water diluted with a neutral detergent, and then wring it out for cleaning. Small laser leveling machine manufacturers remind everyone not to use volatile oil, thinner, gasoline and other chemicals Clean and wipe. Small laser leveling machine pouring leveling construction and control items: 1. Preparation ①. After the base layer is processed, the small laser leveling machine is debugged, and the fixed reference level is drawn according to the original level; the non-woven fabric is laid, the side mold is supported, the laser transmitter is erected, and the ground is leveled according to the original level. Elevation introduced a small laser leveling machine. Small laser leveling machine manufacturer ②, conveying concrete Commercial concrete is used, and the commercial concrete is transported to the entrance and exit of the garage by tank truck, and then transported to the construction site by a three-wheel dump truck. ③, standard college verification Use a handheld laser receiver to check the level of the floor, introduce the level into a small laser leveler, and adjust the reference point (±0.00) on the leveler. 2. Concrete pouring Pouring steps: ① After the formwork is supported, the warehouse should be cleaned one day in advance and rinsed and soaked with water before pouring concrete. When pouring is approaching, drain the open water and sweep the cement slurry or interface agent. At this time, no obvious water accumulation is strictly prohibited. If there is, it must be resolutely removed before paving concrete. Small laser leveling machine manufacturer ②. After the concrete is put down, it should be preliminarily leveled, and the leveling height should be 3 cm thicker than the elevation. Then level it with a small laser leveler. The corners that cannot be leveled can be leveled with a gasoline leveler or manually. ③ When the warehouse near the wall is being poured, after the leveling machine walks over, it must be scraped with a scraper in time. and so on. ④. For areas where concrete mixer trucks cannot be driven to the site, tractors must be used to transfer concrete. After the pouring is completed, the floor finishing construction begins when the concrete is initially set. 3. Receiver signal adjustment during construction The laser signal (frequency of 10 times/second) received by the receiver of the small and medium-sized laser leveling machine in construction automatically adjusts the elevation in real time to ensure that the construction elevation is always at the set standard. Because the laser transmitter is fixed after being set up, it can ensure that the construction of a large area of ground does not produce cumulative errors. During construction, the operator uses a hand-held laser receiver to detect the ground after the construction of the machine to ensure that the flatness error is within the controllable range.

    "Technology brings development" is true. Compared with more traditional floor machinery and equipment, the emergence of laser leveling machines is all the rage. As a mechanical equipment, it can effectively help our floor industry construction workers shorten the construction period and improve the construction quality. Today, let's take a look at the advantages of the DZ25-2 laser leveling machine, which makes us so fascinated by it. The unique hand-held and dual control modes allow our construction workers to control freely and flexibly. Only one person is needed to operate this machine for construction. The two wheels move independently, which is convenient and flexible. Because it is equipped with an electric-driven two-wheel walking system, the wheels can move independently and do not affect the construction of the front leveling head. We can manually control the forward, backward, steering and travel speed of the wheels, which is very convenient to move. The leveling head is composed of scrapers, vibrators, vibration plates and other components, and all materials are made of magnesium alloy used in aviation. The integrated leveling head integrates multiple processes such as leveling, leveling, and vibration, and is completed by the machine at one time. It is both efficient and labor-saving. The high-frequency vibrator of 4,000 times per minute ensures a more stable construction quality. The uniform high-frequency vibration of the vibration plate of the leveling head makes the concrete floor dense and avoids cracking of the floor caused by deformation. It can effectively solve the problems of hollowing, peeling, cracking and inequality of the floor. Some people may ask, what is the magic of the "laser" of the laser leveling machine? Don't worry, the magic will of course be put at the end! Don't you think so? The laser transmitter of the DZ25-2 laser leveling machine is arranged independently, so that we can ensure the consistency of the ground elevation when paving a large area as a whole, without any error. When carrying out large-scale block construction, it can also reduce construction joints, greatly reducing the cost of later maintenance of the ground. Concrete laser leveling machine The most magical laser measurement and control system can automatically control the elevation. This is because the design elevation of the top surface of the floor is automatically controlled by the laser machine computer, which ensures the flatness of the higher ground. It can directly achieve accurate leveling on the concrete layer. The flatness of the ground is not affected by the vibration of the construction template. There is no need to support the template in the middle, which reduces the input of labor and materials, reduces the construction procedures, and speeds up the construction progress. Some people will ask, what is the construction efficiency? 300 square meters of construction area per hour, about 3,500 square meters of construction work per day, don't you like such construction efficiency? I can't wait to get a few machines and put them into construction as soon as possible.

    Common mistakes during the construction of laser leveling machines are usually not due to faults of the machine itself, but rather problems in the systematic coordination of the four dimensions: signals, materials, operations and mechanical conditions. Below, based on the information I have searched for, I have compiled these common errors, quick troubleshooting guides and fault resolution procedures for you. Error Categories Typical phenomenon The root cause Quick solution 1. Signal and System Error The overall ground elevation has shifted, wave-like patterns have appeared, or the machine operation has been irregular. The laser transmitter is installed on unstable foundations (such as soft soil, vibrating floor slabs); the signal is blocked or interfered with by strong light or reflective objects (glass, stainless steel); strong winds cause the transmitter to shake. Check immediately: Ensure that the tripod of the transmitter is firmly fixed on a solid base. Physical isolation: Remove any obstacles between the receiver and the transmitter, and install a windproof cover or counterweight on the transmitter. Avoid interference: Keep the cable of the concrete pump truck away from the transmitter support. 2. Concrete material error The slump variation is significant, resulting in some areas of the ground being too high (too dry) or too low (too soft); "cold joints" or inconsistent hardness occur at the seams. The slump of the concrete does not match the laser leveling machine. The optimal range is usually 140mm ± 20mm. If it is too dry (< 100mm), the machine cannot move; if it is too thin (> 200mm), it is prone to segregation. Source control: At the mixing station, the mix ratio is strictly controlled. The slump of each truckload of concrete upon arrival is measured, and if it fails to meet the standards, it will be rejected or the mix will be adjusted. The supply of concrete was discontinuous, and there was a significant difference in the performance of the concrete between the front and rear vehicles. Ensure continuous pouring: The feeding rhythm is reasonably arranged to avoid long intervals. 3. Operator's mistake After leveling, the ground has knife marks, waves, or edges that have collapsed. Improper control of the working head: If too much material is piled up before leveling the head (exceeding half the height of the spiral working head), it causes excessive resistance and the machine body lifts up; if there is too little material, it cannot level the low areas. Control the uniform speed and material quantity: The operator and the discharging workers closely cooperate, maintaining an excess of approximately 2-3 centimeters of material before reaching the leveling head. Using marking lines for assistance: Draw lines on the ground and ensure that the overlap width is consistent each time. Excessive speed: The hydraulic system cannot respond in time. Generally, it is recommended to maintain a speed of 3-5 meters per minute. Incorrect overlap width: If the overlap between adjacent processes is too wide or too narrow, the standard overlap width is usually 15-30 centimeters. 4. Mechanical state error Regular stripes appear on the ground, or the machine operates with sluggishness and tremors. Inconsistent tire pressure: A large pressure difference between the left and right wheels causes the leveling head to sway left and right, resulting in wave patterns. Daily start-up inspection: Measure and standardize the tire pressure of all four wheels. Wear of vulnerable parts: Uneven wear of the scraper plate and base plate will cause "grooves" to appear, and wear of the spiral feeder affects the uniformity of the material distribution. Daily maintenance: Clean thoroughly after each use, especially paying attention to the concrete on the screws and scrapers to prevent damage to the components after hardening. Check all bolts and tighten them. Hydraulic system response lag: High hydraulic oil temperature or blocked valve groups cause delayed execution of instructions. Critical gap inspection: Ensure that the installation gaps of components such as scrapers and augers meet the standards (for example, the scraper is 1/4 inch higher than the auger). When problems occur during construction, follow the principle of "from outside to inside, from simple to complex" to conduct a rapid diagnosis. Immediately stop the machine, turn off the laser transmitter, and ensure safety. Check if the "eyes" are clean: Clean the sensing panel of the laser receiver and the window of the laser transmitter to ensure there is no cement slurry or dust covering. Check if the "energy" is sufficient: Confirm that the laser transmitter, receiver, and remote control batteries are fully charged, and all cable plugs are securely connected. Situation A: No signal or weak signal from the receiver Confirm the transmitter status: Is it turned on and in rotation mode? Is the horizontal bubble centered? Check height and position: Is the receiver within the effective working height range of the laser transmitter? Move the movable receiver closer to the transmitter for testing. Exclude interference: Is there strong sunlight direct exposure? Try installing a shading cover. Situation B: Unstable signal, machine shakes up and down Check the foundation: Is the tripod of the transmitter stable? Is the ground vibrating? Check mechanical connections: Are the connections between the receiver and the mast, and the mast and the vehicle body firm? Is the gap at the leveling head too large? Check electromagnetic interference: Are the laser system cables bundled with power lines and hydraulic pipes? They should be arranged separately. Situation C: Continuous deviation in leveling accuracy (inaccurate elevation) Calibrate the laser transmitter: This is the most critical step! Use the random accompanying calibration tools to check and calibrate the horizontal accuracy of the transmitter. Check reference points: Reconfirm the absolute elevation of the construction benchmark points (marks) to see if it is correct. Check mechanical linkage: Manually operate the hydraulic lifting, check if the cylinder movements are smooth and powerful, and if there is any jamming or internal leakage. Situation D: Abnormal walking system (unable to walk, one side weak, walking deviates) Check emergency stop and mode: Has the emergency stop button been pressed? Is the working mode correct? Check mechanical jamming: Are the walking wheels or tracks stuck by concrete blocks? Check hydraulic system: Is the hydraulic oil level normal? For single-sided faults, try swapping the hydraulic pipes on both sides. If the fault phenomenon shifts, it can be determined to be a problem with the motor or valve group. Establish a standard procedure to minimize the impact of faults on construction: Fault reporting: The operator discovers a fault and immediately reports it, describing the phenomenon and the time. Quick analysis: The maintenance team quickly locates the cause based on the phenomenon and the above troubleshooting steps, and formulates a plan. Supplies and tools: On-site should always have spare parts (such as sensors, sealing rings, filter elements, etc.) and specialized tools readily available. Fault repair: Carry out the repair according to the plan. Record and analysis: Record the type of fault, the cause, and the solution method. Regularly analyze to avoid recurrence. Three checks every day: Before starting work, check the installation point of the laser transmitter, tire pressure, and the slump of the first batch of concrete. Dual insurance: 2 meters behind the leveling machine, arrange workers to use a 3-meter scraper for fine adjustment to eliminate small defects at the machine's turning or joint. Technical upgrade: Consider introducing equipment with remote monitoring and fault diagnosis systems. Such systems can monitor key parameters in real time, achieve preventive maintenance, and issue warnings before faults occur, turning "unexpected shutdowns" into "planned maintenance", greatly ensuring the construction schedule.
