Description

Technical Field

[0001] The utility model relates to the technical field of bridge drainage, in particular to a bridge expansion joint water collecting device. Background Art

[0002] At present, more and more viaducts are being built, and the phenomena of water seepage and falling objects at the expansion joints of viaducts are becoming more and more serious. The expansion joints of bridges are generally composed of three parts: cover plate, water stop and base. The water stop is the water collection tank of the expansion joint. How to safely and effectively prevent water seepage and falling objects at the expansion joints of bridges can ensure the durability of bridges during operation and avoid secondary safety accidents.

[0003] In the prior art, common practices for bridge expansion joint water collection devices are as follows: 1. In the first practice, a drain pipe is installed at the low point of the waterstop of the expansion joint of the bridge deck, and the water in the expansion joint is led to the drainage system of the bridge deck through the drain pipe; 2. In the second practice, the bridge expansion joint and its waterstop are replaced as a whole, and a drain pipe is installed at the low point of the waterstop.

[0004] The above two methods have the following main defects: 1. The first solution directly cuts grooves at the low point of the existing waterstop during construction, and the installation of drainage pipes can only solve the problem of water seepage at some expansion joints, but cannot solve the risk of falling objects from high altitudes at the expansion joints; 2. The second method adopts the overall replacement of the bridge expansion joint and its waterstop, and installs drainage pipes at the low point of the waterstop. The workload of on-site dismantling is large, which is neither economical nor can it be solved once and for all.

[0005] Therefore, how to solve the risks of water seepage and falling objects at expansion joints and reduce construction workload and construction costs has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0006] In view of the above-mentioned defects of the prior art, the utility model provides a bridge expansion joint water collecting device, one purpose of which is to reduce the risk of water seepage and falling objects at the bridge expansion joint; another purpose is to reduce the construction workload and construction cost of the waterstop strip at the bridge expansion joint.

[0007] In order to achieve the above technical objectives, the utility model provides a bridge expansion joint water collection device, including a water collection trough arranged at the expansion joint between beams, the water collection trough is arranged at the bottom of the expansion joint and arranged along the transverse direction of the bridge, and the water collection trough is respectively provided with water collecting troughs at the lowest points on both sides of the water collection trough near the bridge piers, and a drainage pipe is arranged at the bottom of the water collecting trough, and the drainage pipe is laid along the bridge pier and finally connected to a nearby drainage well.

[0008] Preferably, the water collecting groove is an arc-shaped sealing belt with two ends extending horizontally for a distance;

[0009] The two ends of the sealing belt are connected to the beam body through adhesives respectively, and the side of the sealing belt located at the top of the green belt is connected to the beam body through expansion bolts.

[0010] Preferably, the sealing tape is an FPO sealing tape, and the adhesive is a thixotropic epoxy adhesive.

[0011] Preferably, the drain pipe and the water collecting tank are an integrated structure, and both the drain pipe and the water collecting tank are made of UPVC material.

[0012] Beneficial effects of the utility model:

[0013] 1. The utility model adopts arc-shaped FPO sealing tape as the water collection groove, which is connected by a thixotropic epoxy adhesive. It can effectively prevent water seepage at the expansion joint of the beam body, ice cone phenomenon and the generation of high-altitude falling objects, and has high safety.

[0014] 2. The utility model adopts arc-shaped FPO sealing tape as the water collection trough, which eliminates the need to replace the bridge expansion joint and its waterstop as a whole, and eliminates the need to set a drainage pipe at the low point of the waterstop. This greatly reduces the construction workload and construction cost, has good social benefits, and is suitable for promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS
