How to lay the geomembrane for biogas pools in farms

The construction process of the anti-seepage membrane of the farm biogas pool is divided into the following steps: excavation, pre-buried pipes, digging anchor trenches, laying the bottom black membrane, testing the water at the bottom of the black membrane biogas pool, laying the top membrane and backfilling the anchor trench. At the bottom of the biogas pond, we use a 1.0mm anti-seepage membrane for anti-seepage treatment, and on the top of the biogas tank, we use a 1.5mm HDPE anti-seepage membrane for coverage. Next, we will introduce in detail the laying method of geomembrane sedimentation tanks in livestock farms, including design, material selection, construction and testing.

Design

First, the plan for the geomembrane sedimentation tank needs to be determined. Based on factors such as the size of the farm, the amount of sewage discharge, and the water quality, the size, structural form, and sewage inlet and outlet of the sedimentation tank are designed to ensure that the design of the sedimentation tank is reasonable, safe, and practical.

Material

High-quality geomembrane is an indispensable material for geotechnical sedimentation tanks. It is used to lay the tank body and top membrane layer, which can effectively extend the service life of the sedimentation tank and improve the effect.

In addition to geomembrane, some construction materials are also needed, such as cement, sand, gravel, etc., as well as some auxiliary materials.

Construction

1. Preparation before construction

Before construction begins, the construction site needs to be cleared to ensure the site is level. At the same time, it is also necessary to provide technical guidance to construction personnel and clarify construction requirements and quality standards in accordance with the requirements of the design drawings.

2. Basic processing

In order to ensure the safety and stability of the sedimentation tank, the geomembrane laying must go through the foundation treatment of the base layer.

3. Geomembrane laying

After the foundation treatment is completed, the laying of the geomembrane begins. First, the size and laying position of the geomembrane must be determined according to the design requirements, and the quality of the geomembrane must be checked. Unfold the geomembrane and lay it on the treated foundation, adjusting the position and tightness. During the laying process, care should be taken to avoid scratches, tears and wrinkles.

4. Connection processing

After the geomembrane is laid, connection processing is required to ensure sealing and stability. You can choose to connect the geomembrane by welding or using adhesives, but you must ensure that the design drawings and technical requirements are followed during the connection process to ensure the quality of the project.

Detection

After the construction of the geomembrane sedimentation tank is completed, quality inspection must be carried out to ensure the safety and stability of the project. Specific testing contents include appearance quality testing, strength testing and safety testing.

The laying of geomembrane sedimentation tanks in livestock farms requires comprehensive consideration of design, material selection, construction and testing. In actual operations, technical requirements and specifications must be strictly followed to ensure project quality and use effects. At the same time, daily maintenance and upkeep work must be carried out regularly to detect and solve problems in a timely manner to ensure the normal operation and service life of the sedimentation tank.
