Building foundation anti-seepage membrane connection device and anti-seepage membrane connection method

Abstract

The invention relates to a building foundation impermeable membrane connecting device and a building foundation impermeable membrane connecting method, which are suitable for engineering construction of hydraulic engineering dams, reservoir dams, channels, ponds and the like so as to meet impermeable functional requirements, the tensile strength between new membranes as well as between a new membrane and an old membrane in an impermeable system can be effectively guaranteed, and the impermeable requirements are satisfied. The connecting device comprises inner pipes and outer pipes, wherein insertion openings are axially formed in pipe bodies of the inner pipes, bayonets are axially formed in pipe bodies of the outer pipes, and the outer pipes are clamped on the upper surfaces of impermeable membrane coiling layers which are wrapped outside the inner pipes, so that impermeable membranes I and impermeable membranes II which are used by two building foundations are connected together segment by segment, and the outer pipes as well as the inner pipes are abutted one by one. According to the building foundation impermeable membrane connecting device and the building foundation impermeable membrane connecting method, the leakage problem of the connecting positions of the impermeable membranes is solved, the impermeable purpose is achieved, and the engineering quality is effectively increased.

Description

technical field [0001] The invention relates to a connection method of an anti-seepage membrane in infrastructure construction, in particular to a construction foundation anti-seepage membrane connection device and an anti-seepage membrane connection method, which is suitable for water conservancy project dams, reservoir dams, channels, ponds, etc. with anti-seepage function In the required engineering construction, it can effectively guarantee the tensile strength between the new membrane and the new membrane, and between the new membrane and the old membrane in the anti-seepage system, and meet the anti-seepage requirements. Background technique [0002] The anti-seepage membrane can ensure the anti-seepage requirements of the building foundation, and is widely used in the construction of water conservancy project dams, reservoir dams, channels, ponds and other engineering constructions that require anti-seepage functions. [0003] For a long time, the connection construct...

Problems solved by technology

During the operation, it is easy to apply glue unevenly and have different thickness, and it is easy to form bonding blind spots and leakage points

[0006] 3. Folding method, manually clean the connection part of the impermeable membrane, and then perform folding treatment. Although this method is simple to deal with, the water blocking effect is poor and the anti-seepage effect cannot be achieved.

The conventional process not only requires mechanical equipment and chemical raw materials, but also the quality of the project is unstable, the anti-seepage effect is not good, and the joint parts are very easy to seep, forming a water seepage channel, causing serious damage to the physical structure of the project, and seriously threatening the construction quality and maintenance of the project. quality of engineering
