Connecting structure for flexible vertical assembly partition wall lock catch and waterproof layer

Abstract

The invention belongs to a connecting structure for a flexible vertical assembly partition wall lock catch and waterproof layer. The connecting structure comprises outer plates, a waterproof structure is arranged between the outer plates, the waterproof structure comprises middle connecting plates, an outer connecting plate, an expansion waterproof strip, waterproof cloth and a connecting part, the middle connecting plates are fixed on the surface of the outer plates, the outer connecting plates are fixed to the surface of the outer plates and located at the two ends of the middle connecting plates, the expansion waterproof strips are located between the middle connecting plates, and the waterproof cloth is fixed to the surface of the outer plates through the connecting parts. According to the connecting structure, butt joint splicing is adopted, and the expansion waterproof strip is arranged in the middle, so that the waterproof effect is enhanced while auxiliary fixing is achieved, and the waterproof cloth fixing position is fixed in a wrapping mode.

Description

technical field [0001] The invention belongs to the technical field of environmental protection engineering, and in particular relates to a flexible vertical partition wall lock and waterproof layer connection structure. Background technique [0002] In the field of environmental protection, underground soil and water bodies are polluted, such as groundwater pollution caused by leachate leakage from domestic garbage dumps, soil pollution caused by organic chemical industry spread, and more and more incidents of underground soil pollution have been exposed. [0003] The eradication of pollution sources is not a one-day effort, but the spread of the pollution radius is increasing year by year, threatening human life and survival at all times; therefore, the control of pollution sources is particularly important. The flexible vertical barrier wall technology with its floor area The advantages of small size, quick effect and corrosion resistance are gradually being applied to th...

AI Technical Summary

Problems solved by technology

[0004] The flexible vertical barrier wall is vertically formed into a groove, and then the HDPE membrane is installed vertically inside the groove. Each HDPE membrane unit is connected by a lock, which can block the flow of underground polluted water and prevent the spread of polluted groundwater. Play a closed control of the pollution source; in the flexible vertical barrier wall technology, after the HDPE film is installed, the HDPE film needs to be connected through the interlock between the locks, but there are cavities and gaps between the connecting locks, which is easy Cause liquid leakage and affect the treatment effect, so it is urgent to improve the structure and process
