Easily cleaned filter drain hole for bridge maintenance

Abstract

The invention discloses an easily cleaned filter drain hole for bridge maintenance. The filter drain hole comprises a base and a water guide pipe pre-buried on a base body of a bridge, wherein a through hole and the water guide pipe share a central axis, and a filter assembly used for filtering sundries is embedded in the base; the filter assembly is connected with a piston plate through a telescopic mechanism, and the piston plate is slidably connected in the water guide pipe; and a first drain pipe and a second drain pipe are sequentially and fixedly connected to the side wall of the water guide pipe from top to bottom, and both the first drain pipe and the second drain pipe communicate with the water guide pipe. The easily cleaned filter drain hole has the beneficial effects that the sundries in rainwater can be collected through the rainwater passing the filter assembly, so that the sundries are prevented from entering the water guide pipe, and blockage of the water guide pipe is avoided; a filter screen at the joint of the first drain pipe and the second drain pipe and the water guide pipe can further filter the rainwater, so that the filtering effect is improved; and the piston plate can automatically adjust the water discharge amount according to the rain water amount, so that the filtered sundries can be conveniently cleaned.

Description

technical field [0001] The invention relates to the technical field of bridge drainage structures, in particular to an easy-to-clean filter drain hole for maintenance bridges. Background technique [0002] During the use of the drain hole in the bridge project, it is easy to be blocked by leaves, garbage, stones and other sundries, which makes drainage difficult and makes the rainwater accumulate on the bridge, which not only affects the driving safety but also affects the service life of the bridge. The drain hole When draining, it is easy to accumulate some sundries inside, which is not easy to clean up, increases the workload of maintenance personnel, and affects the normal use of the weep hole. [0003] In order to solve the above problems, we propose a kind of easy-cleaning and filtering scupper for maintenance bridges. Contents of the invention [0004] The object of the present invention is to provide an easy-to-clean filter drain hole for maintenance bridges in vi...
