Waterproof method for prefabricated reinforced concrete box culvert interfaces and interface water stopper

Abstract

The invention discloses a waterproof method for prefabricated reinforced concrete box culvert interfaces and an interface water stopper. The waterproof method comprises the following steps of: pre-forming a first groove at a predetermined position far from a first box culvert interface, and pre-forming a second groove at a predetermined position far from a second box culvert interface; injecting epoxy resin adhesive into the first groove and the second groove respectively; and plugging two wings of the interface water stopper into the first groove and the second groove respectively, and sticking the two wings of the interface water stopper in the first groove and the second groove after the epoxy resin adhesive is solidified, wherein the two wings of the interface water stopper are provided with an anchoring part respectively, and the transverse size of the section of the anchoring part is greater than that of the middle section of the interface water stopper. According to the waterproof method for the box culvert interfaces, the two wings of the interface water stopper are stuck into the grooves of the box culvert interfaces to finish sticking, and the interface water stopper is adopted for preventing water; and compared with a conventional O-shaped rubber ring waterproof method, the method has the advantages of high waterproof reliability and long service life.

Description

technical field [0001] The invention relates to building waterproofing, in particular to a waterproofing method for the interface of a prefabricated reinforced concrete box culvert and an interface waterstop. Background technique [0002] According to the conditions provided by the project, the size of the box-shaped pipe can be adjusted reasonably to meet different work requirements. It is suitable for underground traffic culverts, urban rainwater, sewage pipes, water supply pipes, drainage channels, etc. The box-type prefabricated assembly method occupies a relatively large proportion of underground pipelines in foreign countries and is widely used in engineering. Similar projects in China use the method of pouring on site. [0003] The prefabricated assembly method has the following advantages: 1. In urban municipal engineering, the construction period is short and the impact on urban traffic is small; 2. The quality of the prefabricated concrete is good and the anti-leak...

AI Technical Summary

Problems solved by technology

For mechanical products, it is easy to control the machining dimensional accuracy, but it is very difficult for concrete products, especially large concrete prefabricated parts

According to the requirements of the manufacturing process, the error of the width and height of the box culvert is ±10mm, so the maximum error of the socket gap can reach 20mm. In this case, the compression amount of the O-shaped rubber ring cannot be controlled. It can be seen that the O-shaped The rubber ring is suitable for medium and small precast concrete pipes with small size error, but not for large prefabricated reinforced concrete box culvert with large size error
