Expansion joint multilayer combined type water stopping device of underground engineering and manufacturing method thereof

Abstract

The invention relates to the field of arrangement or structure of foundation structure joints of underground or underwater structures, in particular to an expansion joint multilayer combined type water stopping device of an underground engineering and a manufacturing method thereof. The device comprises a wall body (1), the wall body (1) is characterized by further comprising an anti-sticking self-adhesive waterproof roll material (21), a metal water stop strip (22), a rubber water stop belt (23), a steel edge rubber water stop belt (24), a fastening bolt (31), a steel shear pin (32), and a waterproof agent (4); the manufacturing method of the expansion joint multilayer combined type water stopping device of the underground engineering is characterized in that the method is implemented according to the following steps that A, a construction platform is reserved; B, a box type end mold and right angle nails are prefabricated; C, a frame is erected; D, the water stop belts are laid; E, the a box type end mold is erected; and F, the right angle nails are erected. According to the device and the method, the construction technology is simple, the construction investment is small, and the water stopping effect is good.

Description

technical field [0001] The invention relates to the field of the layout or structure of the joints of the basic structure of underground or underwater structures, in particular to a multi-layer combined water stop device for expansion joints in underground engineering and a manufacturing method thereof. Background technique [0002] At present, the development of underground space is the mainstream trend of current development, and accordingly, the number of underground projects has increased significantly. The development and utilization of underground space will inevitably involve how to control groundwater and how to stop water. Most underground projects now have water leakage and water seepage, especially in cities with high groundwater levels and coastal cities. [0003] At present, the location of the expansion joints in the underground space is mostly designed with impermeable concrete, mid-buried waterstops, externally attached waterproof membranes and waterproof co...

AI Technical Summary

Problems solved by technology

However, if the floor structure is thin, how to implant a variety of mid-buried water-stop structures in the floor and ensure the construction quality of the expansion joints is a big problem in the construction process.
