Composite drainage network The mat not only removes groundwater and prevents soil erosion, but also improves the bearing capacity and stability of the foundation.
1. Preparation before construction
Before construction, the construction area should be cleaned to ensure that the ground is flat and free of debris. Some places with uneven foundation or potholes should be filled to ensure that the composite drainage net mat can be laid smoothly and tightly. The quality of the composite drainage net mat should also be strictly inspected to ensure that it meets the design requirements and relevant specifications. For example, check the appearance quality, dimensional deviation, physical and mechanical properties and other indicators of materials.
2. Laying and fixing
When laying composite drainage net mats, the laying sequence and location should be determined according to the design requirements. When laying, ensure that the net mat is flat and wrinkle-free, and strictly follow the design drawings. Where lap is needed, it should be lap according to the specified lap width and fixed with special tools or materials. During the fixing process, make sure that the drainage mat does not shift or fall off, so as not to affect its drainage effect.
3. Connection and backfilling
During the laying process of composite drainage net mats, if multiple net mats need to be used for splicing, special connecting materials should be used for connection, and the connections should be ensured to be smooth and firm. After the connection is completed, backfill construction should be carried out. When backfilling soil, it should be compacted in layers to ensure that the quality of backfill soil meets the requirements of the specification. During the backfilling process, excessive pressure should not be applied to the net mat so as not to damage its structure.
4. Construction environment requirements
The construction environment of composite drainage net mat has an important influence on its performance. During the construction process, it cannot be carried out in rainy and snowy weather, which will affect the adhesion and waterproof effect of the drainage mat. The construction area should be kept dry and ventilated to ensure the construction quality and safety.
5. Construction quality inspection and acceptance
After the construction is completed, the laying quality of the composite drainage net mat should be tested. For example, drainage performance, flatness, joint firmness, etc. If a problem is found, it should be dealt with in time to ensure its long-term stable operation. Acceptance work should also be carried out to ensure that the construction meets the design requirements and relevant standards and specifications.
6. Maintenance
After the construction of the composite drainage net mat is completed, it needs regular maintenance. Such as checking the integrity of the drainage mat, the firmness of the connection and cleaning the drainage channel. Through regular maintenance, problems can be found and solved in time to ensure the long-term stable operation of the drainage mat.
It can be seen from the above that the construction technology requirements of composite drainage net mat are very strict, including pre-construction preparation, laying and fixing, connection and backfilling, construction environment requirements, construction quality inspection and acceptance, and maintenance. Only by strictly following these requirements can we ensure the best effect of composite drainage net mat in civil engineering and provide a strong guarantee for project quality and safety.
