    The construction plan for a concrete laser leveling machine must be tailored to the project type (e.g., industrial plant, underground garage, large plaza, etc.), concrete grade, and site conditions. The core design principle is "standardized processes and controllable precision." The following is a general plan framework and examples of typical scenarios: Floor Flatness Error: ≤3mm/2m (core indicator for laser leveling); Concrete Density: ≥98% (avoiding sanding and hollowing); Construction Schedule: Planned based on a "500-800㎡/shift" (per machine). Stages Key Work Areas Core Requirements 1. Construction Preparation ① Base Preparation: Compaction (compaction degree ≥ 95%), debris removal, and watering (no water accumulation); Base leveling error ≤ 5mm/2m; Laser signal unobstructed (avoid metal and strong light). ② Laser System Commissioning: Transmitter calibration (horizontal error ≤ 0.1mm/m), receiver sensitivity test; ③ Material Preparation: Concrete (slump 120-160mm, initial setting ≥ 4h), geotextile/plastic film curing 2. Concrete Pouring ① Spreading: Use a tanker or concrete spreader to spread the material evenly, 30-50mm above the design elevation (allowing for leveling margin); Material spreading speed matches leveling speed (no accumulation or material shortages); Bin seams align with subsequent expansion joints. ② Combination Casting: For large areas, divide the concrete into 6-8m wide compartments (with temporary dividers) to prevent cracking after initial setting. 3. Laser Leveling ① Equipment Movement: Drive at a constant speed (0.8-1.2m/min), following a "horizontal back-and-forth" pattern with staggered overlaps; Real-time monitoring of the laser receiver (steady green indicates normal operation); immediate shutdown and calibration if deviation exceeds 2mm. ② Vibration Control: Insert the vibrator ≥ 50mm (penetrating the current paving layer) to ensure the connection between the upper and lower layers. 4. Finishing ① Rough Finishing: After the leveling passes, manually use a scraper to assist with leveling (to address any minor vibration leaks or unevenness). Timing of fine cutting is critical: premature cutting can lead to sanding, while delayed cutting may prevent surface air bubbles. ② Fine Finishing: After the concrete surface has cleared of water seepage (no noticeable indentations when pressed with a finger), use a trowel (with a disc) to smooth the surface 2-3 times. 5. Curing ① Covering: Cover with geotextile/plastic film within 1-2 hours of completion (before initial setting). No personnel or material stacking is permitted during the curing period; avoid freeze-thaw cycles in winter. ② Moisturizing: Water the surface every 2 hours in summer (to keep the film moist), and cover with a thermal blanket in winter (curing temperature ≥ 5°C). ③ Curing Time: ≥ 7 days (≥ 14 days for C30 and above concrete). 6. Expansion Joint Cutting ① Timing: 24-48 hours after pouring (surface hardness reaches 1.2 MPa, and no visible marks are visible when scratched with a fingernail). Clean the seams after cutting and apply sealant later to prevent water seepage. ② Specifications: Joint depth = 1/3-1/4 of the floor thickness, spacing ≤ 6 meters (required for areas over 36 square meters), joint width 5-8 mm. Key Differentiations: Concrete Grade: C35/C40 (one grade higher than standard flooring) is used, with polypropylene anti-cracking fiber (0.9 kg/m³) added to reduce thermal cracking. Laser System: Due to obstruction by pillars in the garage, a "multi-transmitter zoned coverage" system (one transmitter every 15-20 meters) is used to avoid signal blind spots. Surface Optimization: After finishing, diamond wear-resistant aggregate (5-6 kg/m²) is applied, followed by finishing with a high-speed trowel to improve surface hardness (Mohs hardness ≥ 6). Key Differentiators: Base Reinforcement: 300mm thick graded sand and gravel with a 150mm thick C25 cushion layer (50% thicker than standard flooring) ensures a load capacity of ≥5t/m2; Leveling Parameters: Vibration frequency is adjusted to 60-70Hz (compared to 50Hz for standard flooring) and travel speed is reduced to 0.6-0.8m/min to enhance concrete density; Post-treatment: After curing, a sealant and curing agent treatment (penetration depth ≥5mm) is applied to improve the floor's compressive strength (≥80MPa) and impermeability. Key Differentiations: Optimized Compartmentalization: Compartments are divided into 10m x 10m squares (common flooring requires 6-8m). Expansion joints (filled with foam board) are provided to relieve thermal stress. Concrete Control: Low-heat cement (heat of hydration ≤ 270kJ/kg) is used, and a retarder is added in summer (extending the initial setting time to 6-8 hours) to prevent cracking due to temperature differences. Laser Calibration: Transmitter levelness is rechecked every 2 hours (common flooring requires 4 hours). Because the plaza is unobstructed, a wind shield is required to prevent strong winds from interfering with the signal. Staffing: Each machine is equipped with one operator (certified) + two fabricators + two finishers + one laser monitor. Equipment Inspection Checklist: Before starting the machine, check the laser transmitter battery, vibrator wear, and tire pressure (tolerance ≤ 0.1 MPa). Emergency Plan: If the initial setting of the concrete is too rapid, immediately activate the backup leveling. If the laser signal is lost, switch to manual mode (using the adjacent leveled surface as a reference).   Note: The parameters provided in this document are for reference only and are not mandatory. Due to differences in technical characteristics between different brands and models of laser levelers, please consult the manufacturer for a suitable solution before actual operation. This reference document assumes no responsibility for any issues arising from failure to follow the manufacturer's instructions.
