Abstract

The invention discloses a fixing device for a water-stop belt for a rectangular cross-section of an underground structure and a rapid installation construction method. The rapid installation construction method of the water-stop belt for the rectangular cross-section of the underground structure comprises the following steps of: step (1). performing construction preparation; step (2). surveying, positioning and lofting; step (3). installing and positioning the water stop belt fixing device; step (4). placing circumferential water-stop belts; step (5). constructing a structural baseplate; step(6). installing and fixing the water-stop belts; step (7). constructing side walls and a mid-plate structure; and step (8). connecting connectors of the water-stop belts at the position of a top plate. Only one connector is arranged on the full ring of each ring of water-stop belt; the connectors are arranged on the top plate easy to operate; construction joints of the side walls are formed and installed at one time; the quality of the connectors can be fully guaranteed; the quantity of the connectors is greatly reduced; and the amount of water leaking at the construction joints is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of installation of waterstops for circular construction joints with rectangular sections in underground engineering, in particular to a fixing device for waterstops with rectangular sections in underground structures and a quick installation method. Background technique [0002] With the rapid economic growth, more and more urban underground projects are in full swing and rapid construction. Due to the development of groundwater and the inevitable pressure of construction schedules, a large number of water leakage occurs in the construction and operation of urban subway stations. , especially the construction joints, is the main part where water seepage occurs. However, the construction of urban subway stations has a lot of water leakage, which is difficult to deal with and requires a lot of investment. Therefore, it is of great social significance to study how to effectively construct and ensure the waterp...
