A support device and construction method for plain river dredging engineering

Abstract

The invention discloses a supporting device and a construction method for dredging engineering of plain river courses, comprising a fixing seat, a supporting frame, and a supporting mechanism, a positioning bar limiting a fixing rod, a fixing block provided on the fixing rod, and a fixing groove provided on the fixing block. The fixing seat is provided with connecting blocks, and the connecting blocks on both sides of the fixing block are provided with fixing bolts, and the fixing bolts are arranged in the fixing grooves, and the fixing bolts limit the fixing blocks, the supporting frame is provided with a supporting rod, and the supporting frame is provided with a ferrule, and the supporting frame is provided with a ferrule. The rod is provided with a card rod, the card rod is provided with a ferrule, the support rod is provided with a guide block, the support rod is provided with a chute, and a water retaining mechanism is provided between adjacent support rods; the method adopts six steps. The invention can block river water, facilitate the dredging and cleaning of cross-river roads, effectively shorten the construction period, have simple steps, facilitate construction, effectively improve construction efficiency and construction effect, and shorten construction period.

Description

technical field [0001] The invention belongs to the technical field of river course regulation, and in particular relates to a support device and a construction method for plain river course dredging engineering. Background technique [0002] Water is the blood of a city, it can nourish life, shape the temperament of the city, and reflect the health of the city. At present, the river pollution in our country has reached the point where it has to be treated, especially the water quality of the rivers around the city is affected by factors such as domestic sewage, industrial sewage discharge, non-point source pollution of agricultural production points, urban garbage abandoned rivers and other factors, resulting in the serious loss of ecological functions of urban rivers . The river flows through the culvert pipes buried in the lower part of the road. The culvert pipes occupy the effective flood discharge section of the river, and the flow capacity of the culvert pipes is low...

AI Technical Summary

Problems solved by technology

Most of the existing dredging projects for cross-river roads require the demolition of the original roads and the erection of passage bridges with strong flow capacity to ensure the traffic capacity. However, when the cross-river roads are demolished, construction waste is likely to be generated, and it is difficult to clean up the waste falling into the river , which not only pollutes the river course, but also requires salvage and cleaning to prolong the project period
