With the rapid development of society and economy, people’s lives are changing with each passing day, and their material life is rich and colorful. Many problems have arisen. Among them, environmental protection is particularly prominent. How to do environmental protection engineering construction is the proposition given to us by the times. .

The process of impermeable geomembrane is the most critical process in the anti-seepage system of environmental protection engineering. The success or failure of the entire project depends on the construction quality of the artificial impermeable layer. That is to say, once the impermeable membrane leaks, it will cause groundwater source pollution. The consequences of a series of environmental problems such as land pollution and land pollution will be irreparable.

1. Material preparation: The performance index of the purchased impermeable geomembrane meets the national technical standards of impermeable geomembrane.

Standard: GB/T17643-2011, the national standard has specific parameter requirements for various specifications of composite geomembrane.

2. Preparations before construction:

1. Before laying and installing the anti-seepage geomembrane, the owner, designer, site supervisor and relevant units are invited to conduct a pre-construction preparatory meeting. The meeting will finally determine the construction details of the anti-seepage construction and solve various new problems on the construction site. Case.

2. Do a good job in the maintenance and unblocking of the power line before construction; the maintenance of construction machinery and tools is in place; labor arrangements are in place and all preparations are made.

3. The construction must be carried out only after the approved documents and the written consent of the project supervisor on the construction proposal plan have been obtained. Records should be made during construction and submitted to the owner for filing for future reference.

4. Construction equipment, machinery and HDPE geomembrane materials should be inspected before construction. The HDPE geomembrane material certificate should be kept for future reference. The material of HDPE geomembrane must be approved by the supervising engineer before construction.

3. Construction conditions:

1. Base preparation:

1) Check and confirm that the foundation support layer has the conditions for laying composite geomembrane. The base surface should be dry (including

The water rate should be controlled below 15%) compaction (uniform compaction, compaction coefficient ≥0.95). The surface is smooth, no cracks, no muddy, no depressions, and uniform slope. The flatness in the film should change gently, and the yin and yang corners are smooth.

2) Sweep the surface of the geomembrane, there should be no sharp objects, stones, iron wires, wooden sticks, etc., seepage prevention range

The inner turf and tree roots should be removed, and weeds should be sprayed with herbicides.

2. Testing of anti-seepage geomembrane:

1) Cutting material analysis, reasonable cutting.

2) Check the appearance of the composite geomembrane, record and repair damages, holes and other defects;

3) Do the test section to determine the welding temperature, speed and other construction process parameters.

4) Before laying the composite geomembrane, use a road roller to statically press both sides to close the surface.

3. The main labor force that each construction technician needs to be equipped with: 1 mechanic (responsible for lifting the compound

Geomembrane), 1 line worker, 1 electrician, 5-6 assistant general workers (adjustable with the progress of the project).

Our company, Shandong Jianbiao Technical Testing and Testing Co., Ltd. (JBJC for short) is a testing and testing organization with CMA testing qualification approved by the State Quality and Technical Supervision Bureau and established in accordance with the law. In order to ensure the ecological safety of environmental protection projects, Shandong Jianbiao Technology Test and Inspection Co., Ltd. was established in August 2016. The company is engaged in the detection of environmental protection related materials such as building waterproof materials, geosynthetics, and leakage detection of anti-seepage engineering anti-seepage systems. With the large-scale application of anti-seepage materials and building waterproof materials in related projects, the safety of project leakage directly affects the safety and quality of the project. Leakage detection can objectively, fairly, scientifically and effectively supervise the project quality to truly ensure anti-seepage The quality and safety of the project.
