Bridge drain pipe construction installation technology

Abstract

The invention discloses a bridge drain pipe construction installation technology. The bridge drain pipe construction installation technology comprises the steps that a drain pipe hole is buried through a PVC pipe to ensure that the pre-buried hole is perpendicular; concrete pouring is conducted on box girders around the PVC pipe; a drain pipe is fixedly installed after the PVC pipe is removed through chiseling operation; the periphery of the pipe wall of the drain pipe and an installation groove are blocked off through a contraction-free epoxy grouting material. According to the bridge drain pipe construction installation technology, the situations that the drain pipe is installed perpendicularly, and a drain perforated strainer is horizontal are guaranteed, and comfort of vehicle travelling is ensured; the contraction-free epoxy grouting material adopted by the bridge drain pipe construction installation technology is proper in viscosity, and has good filling performance, and pouring construction can be easy; various kinds of padding of the bridge drain pipe construction installation technology can be uniformly distributed in epoxy resin through matching in proper proportions, and have good filling and bonding effects; the contraction-free epoxy grouting material is applicable to construction in various complex environments, and has excellent acid and alkali resistance performance, water accumulation and water seepage cannot happen after grouting construction is accomplished, blocking is firm and dense, and compressive strength is high.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a construction and installation process for a bridge drain pipe. Background technique [0002] my country's bridge drainage generally adopts drain pipes to automatically guide water outwards. This drainage method is simple, fast, and practical, but the following problems are prone to occur during installation: the elevation of the drain pipe is higher than the road surface elevation, and the drainage effect is poor during use; The installation of the water pipe is not vertical, resulting in uneven drain grates and poor driving comfort of the vehicle; the seal around the drain pipe is not tight, which is prone to cracks in the building, and water stays from the outer wall of the drain pipe and along the beam, which not only affects the performance of the bridge The appearance, and the cracks will surround and corrode the steel reinforcement placed therein, shorten the se...
