Problems solved by technology

[0003] At present, the existing HDPE geomembrane is affected by the site conditions of many closed anti-seepage projects during use. There are many corners in the installation axis, and HDPE geomembrane is usually used to directly turn the corner. The above method has great limitations and increases HDPE. Geomembrane installation technical difficulty and HDPE geomembrane damage risk

Abstract

The invention discloses an HDPE membrane corner coupling interlocking connection device and a using method thereof. The device comprises a coupling web plate and two groups of latch hook assemblies arranged on the coupling web plate. According to the device, a first latch hook and a second latch hook which are arranged on the same side are arranged on the surface of the corresponding web section to serve as locking components of the connection device, the first latch hook serves as a standard latch hook of the device, a groove is formed in the end of the second latch hook, and after the connection device is connected with two HDPE membranes in an inserted mode, a reserved space is formed in the groove, namely a reserved hole, and a slow expansion water stop strip or a closed grouting pipeor a drainage pipe or other anti-seepage components can be arranged at the reserved hole or a preset detection hose used for later-period monitoring can be arranged at the reserved hole according to the actual use purpose; and when the HDPE membranes need to be turned, the device is installed between the two HDPE membranes, the lock hook assemblies on the device are used for being connected with the two HDPE membranes in an inserted mode to form coupling interlocking, and the two web plate sections of the device are used for forming a needed turning angle.

Description

technical field [0001] The present disclosure generally relates to engineering fields such as civil engineering, mining, water conservancy and environment, and specifically relates to a HDPE diaphragm corner coupling interlocking connection device and a method for using the same. Background technique [0002] HDPE diaphragms are now widely used in domestic civil engineering, mining, water conservancy and environmental engineering fields, as anti-seepage or isolation, with very good corrosion resistance and ductility. In China, the HDPE anti-seepage membrane with a thickness of 3mm and a width of more than 6 meters has been maturely produced. It is lapped into any width by using mature hot-melt welding, and the detection technology is mature. It has been widely used in open-air landfills, tunnels and underground. Engineering fields such as waterproofing or isolation barriers of structures. [0003] At present, the existing HDPE geomembrane is affected by the site conditions ...
