Waterproof structure of culvert and construction method thereof

Abstract

The invention relates to the technical field of culvert waterproofing, in particular to a waterproof structure of a culvert. The waterproof structure of the culvert is characterized in that the waterproof structure of the culvert comprises two side walls of a culvert body, multiple cover plates covered on top of the side walls, a deformation joint waterproof structure arranged between adjacent cover plates, and a waterproof board coated on the side walls and the outer sides of the cover plates; the deformation joint waterproof structure comprises a rubber airbag that can be filled and deflatedrepeatedly, and a drain pipe; the length direction of the rubber airbag is consistent with the length direction of the gap between the cover plates and seals the gap; the drain pipe penetrates the waterproof board from the gap between the cover plates; the drain pipe and an inflatable end of the rubber airbag are respectively located on both sides of the cover plates. The waterproof structure ofthe culvert has the advantage of overcoming water leakage defects of traditional culverts with the cooperation of the rubber airbag and the drain pipe to discharge water on the cover plates out of theculvert. Further disclosed is a construction method of the waterproof structure, and the construction method has the advantages of realizing the mounting of the waterproof structure and thus improving the waterproof performance of the culvert.

Description

technical field [0001] The invention relates to the technical field of culvert waterproofing, in particular to a culvert waterproof structure and a construction method thereof. Background technique [0002] As a very important part of highway engineering, culverts play an irreplaceable role in realizing pedestrian traffic under urban roads, surface drainage along highways, and ensuring roadbed safety. Among them, to realize the culvert under the urban road for pedestrians, it is necessary to have certain requirements for the waterproof performance of the culvert itself, so as to avoid the occurrence of water leakage on the roof of the cave and the rain in the cave, which will affect the normal traffic. [0003] In the prior art, culverts in urban roads are mostly assembled by assembled culvert segments and cover plates. In order to improve the waterproof performance of culverts, a building waterproof layer is applied to the surface of the cave body and cover plates or direct...

AI Technical Summary

Problems solved by technology

However, although the waterproof board or the waterproof layer has a certain waterproof effect, once water seeps into or enters the waterproof board or the waterproof layer, the water remaining on the cover plate is difficult to drain out of the cover plate, and will leak along the deformation seam after a long time In the culvert, it affects the traffic in the cave, is not conducive to safe passage, and reduces the life of the culvert; the rubber gasket in the gap is difficult to achieve the sealing and waterproof effect when the ambient temperature is low
