Positioning and moving device for reconstruction construction of water-blocking bridge of river channel

Abstract

The invention provides a positioning and moving device for reconstruction construction of a water-blocking bridge of a river channel, belongs to the technical field of bridge reconstruction, is used for vertical positioning and moving operation of original bridge pier heightening construction, and comprises a lifting mechanism, a fixing mechanism, a pouring mechanism and a supporting mechanism, a formwork is limited and supported through the lifting mechanism, and a reinforcement cage can be fixed through the formwork; therefore, the poured concrete structure is kept in a vertical state, the stability of the pier after heightening is improved, the lifting mechanism can ascend and descend along with the pouring height of the reinforcement cage by cast-in-place concrete, different heights of the formwork are limited in the moving process, and the formwork and the reinforcement cage are accurately positioned at the top of the pier; in the lifting process, the fixing mechanism is used for assisting in supporting the lifting mechanism and preventing the lifting mechanism from sliding down, the supporting stability of the lifting mechanism is improved, cast-in-place concrete in the reinforcement cage is buffered through the pouring mechanism, and the concrete can be conveyed into the reinforcement cage through a conveying pipeline; the conveying pipeline can be suspended through the supporting mechanism, and the discharging end of the conveying pipeline extends into the reinforcement cage.

Description

Technical field [0001] The present invention belongs to the field of bridge reconstruction technology, and more particularly, it is related to a river water supply bridge to renovate the construction of a positioning mobile device. Background technique [0002] The waterproof bridge is a bridge. Generally, the total height of the waterproof bridge used in the river is low. When the water flow in the river is large, from the reverse side, the waterproof bridge can also hinder the water flow, in certain The degree reduces water flow, affecting the stability of river overwater capacity and water-water bridge, therefore it is necessary to convert water bridges. Under normal circumstances, the construction of the waterproof bridge is to increase the bridge pier of the water-water bridge, improve the height of the bridge, to increase the water flow; in the prior art, the increase in the bridge pier is in the original bridge pier. On the basis, increase the concrete structure to raise t...
