A circular drip irrigation maintenance system for railway thin-walled hollow pier

Abstract

Provided is a railway thin-walled hollow pier circulating drip irrigation maintaining system, characterized in that the upper surface of a railway thin-walled hollow pier base is provided with a reservoir and sedimentation basins, the sedimentation basins are internally provided with submersible pumps to transmit clear water in the sedimentation basins to a bucket, and operation and stop of the submersible pumps are controlled manually. After a segment of 3m railway thin-walled hollow pier concrete is completed in pouring, and an inner die and an outer die are dismounted, a first non-woven geotechnical cloth and a third non-woven geotechnical cloth are respectively installed on the inner wall and the outer wall of the railway thin-walled hollow pier, and a first weeping pipe and a second weeping pipe are winded on the first non-woven geotechnical cloth and the third non-woven geotechnical cloth. A first plastic film and a second plastic film are respectively wrapped out of the first weeping pipe and the second weeping pipe. A second non-woven geotechnical cloth and a fourth non-woven geotechnical cloth and respectively wrap the first plastic film and the second plastic film. Ropes, support rods, and back shores are used to install and fix the first non-woven geotechnical cloth, the third non-woven geotechnical cloth, the first weeping pipe, the second weeping pipe, the first plastic film, the second plastic film, the second non-woven geotechnical cloth, and the fourth non-woven geotechnical cloth on the inner wall and the outer wall of the railway thin-walled hollow pier.

Description

technical field [0001] The invention relates to a railway thin-walled hollow pier maintenance system, in particular to a railway thin-walled hollow pier circulation drip irrigation maintenance system. Background technique [0002] In the prior art, bridge piers are an important part of bridges in railways, highways, and municipal engineering. In order to prevent the large temperature difference between day and night in the alpine desert area, and dry and windy sand, after the thin-walled hollow piers of the railway are removed from the formwork, the inner and outer walls of the piers will appear. Drying shrinkage and cracks, according to the normative standard of concrete thermal insulation and moisturizing maintenance for no less than 28 days, the current general pier maintenance methods are artificial water spraying and moisturizing maintenance, non-woven geotextile wrapping and water-proof plastic film moisturizing maintenance, but the method and The process has the follo...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a circular drip irrigation maintenance system for railway thin-walled hollow piers, which solves the problem of large temperature difference between day and night in alpine desert areas and the maintenance problems of railway thin-walled hollow piers, and Flexible operation, economical and practical, not only saves energy and reduces consumption, reduces construction costs, but also improves the maintenance quality of railway thin-walled hollow piers and speeds up the construction progress
