1. Preparation before installation
1. Clean the foundation: Make sure the foundation of the installation area is flat, solid, and free of sharp objects or loose soil. Clean away oil, dust, moisture and other impurities, and keep the foundation dry.
2. Check the materials: Check the quality of the corrugated composite drainage mesh pad to ensure that it is not damaged, not aged, and meets the design requirements and relevant specifications.
3. Formulate a construction plan: According to the actual situation of the project, formulate a detailed construction plan, including construction process, personnel arrangement, material use, etc.
2. Installation steps
1. Laying a cushion: If necessary, laying a layer of sand cushion or gravel cushion on the foundation surface can improve the drainage effect and foundation bearing capacity. The cushion layer should be smooth and uniform, and the thickness should meet the design requirements.
2. Laying the drainage mesh mat: Lay the corrugated composite drainage mesh mat according to the design requirements. During the laying process, the mesh mat should be kept flat and tight without wrinkles or gaps. Special tools or equipment should be used to assist in laying to ensure that the mesh mat is tightly attached to the foundation.
3. Connection and fixation: If the project requires multiple drainage mesh pads to be spliced, special connecting materials or methods must be used to connect them to ensure the continuity of the drainage channels. The joints should be smooth and firm, and no leakage points should occur. Also use clamps, nails and other fixing tools to fix the drainage mesh pad to the foundation to prevent it from shifting or falling off.
4. Backfilling and compaction: After the drainage mesh mat is laid, backfilling construction must be carried out in time. The backfill material should be soil or sand with good water permeability, and should be backfilled in layers and compacted to ensure that the backfill quality meets the specifications. During the backfilling process, the drainage mesh pad must not be damaged or compressed.
3. Precautions
1. Construction environment: Avoid installation and construction in rainy and snowy weather to prevent the adhesion and waterproof effect of the drainage mesh pad from being affected.
2. Construction quality: Construction shall be carried out in strict accordance with the design requirements and relevant specifications to ensure the laying quality and drainage effect of the drainage mesh mat. During the laying process, pay attention to check the flatness and fixation of the drainage mesh mat, and find and deal with problems in time.
3. Safety protection: During the construction process, safety protection measures must be taken to ensure the safety of construction workers. Do not use sharp tools or equipment to cause damage to the drainage mesh pad.
4. Regular inspection and maintenance: During use, the corrugated composite drainage mesh pad must be inspected and maintained regularly. Find damaged or aging parts and repair or replace them promptly to maintain its performance and durability. Also clean the debris and sediment in the drainage channels to ensure smooth drainage.
