Standard requirements for the flatness of concrete pavement 10
The standard requirements for the flatness of concrete pavement vary depending on the type of project, usage function and other factors. Here are some common standards:
General concrete pavement:According to the "Construction and Acceptance Specifications for Concrete Pavement of Highway Engineering" (JTG F40 – 2004), under normal circumstances, the allowable deviation of the flatness of concrete pavement should be controlled within ±3mm.
High-standard pavement such as highways:For highways and other roads with high requirements for driving comfort and safety, the allowable deviation of the flatness should be more stringent, generally controlled within ±2mm.
During the construction process, the use of concrete laser leveling machine (concrete laser leveling machine) can help improve the flatness of the concrete pavement. The concrete laser leveling machine uses the horizontal laser as the reference surface to control the ground elevation, which can effectively ensure the levelness and flatness of the ground. Its application advantages include:
Precise elevation control:The concrete laser leveling machine uses a laser measurement and control system to control the elevation in real time. There is no need to pull a control line for leveling, nor is there a need to support the side template to control the ground elevation, thus avoiding elevation errors caused by template vibration or manual block support during construction.
Extremely small flatness error:When applied to large-area floor construction, the ground elevation is easy to control. The entire floor only requires 1-2 reference point elevations, which can reduce the error caused by multiple reference points. As long as the laser transmitter is not disturbed, no matter where the leveling machine moves, it can ensure that the overall elevation of the paved ground is not affected, and the flatness error is extremely small.
Better ground integrity:Using a concrete laser leveling machine for floor construction, it is easy to achieve one-time overall paving of a large area of floor. It can be divided into blocks as needed, and the construction can be continued until the entire floor is completed, making the ground integrity better.
The ground is more compact and uniform:When the concrete laser leveling machine is leveling the concrete, it is always in a uniform speed construction state. Through the high-frequency vibrator of 4000 times per minute, the vibration plate of the leveling head produces uniform high-frequency vibration, making the concrete ground more compact and uniform.
