Concrete pier repairing construction method

Abstract

The invention relates to a concrete pier repair construction method which uses compaction trowelling equipment. The compaction trowelling equipment comprises a base, a trowelling plate, a lifting plate, a leading-in device, a compaction device and a lifting device. A direction adjusting rotating rod is rotated to drive a guide plate to rotate outwards so that the guide plate inclines to the bottomend of a notch, concrete is conveniently injected along the guide plate, meanwhile, the situation that the concrete flows out after being injected into the notch is avoided, a connecting shaft of a driving motor rotates, then a cam rotates to drive a sliding frame to slide up and down, and therefore the trowelling plate moves up and down to carry out trowelling on the concrete, and meanwhile, anextrusion rod ascends and descends to drive a compaction plate to contract to achieve trowelling on the concrete with the trowelling plate; and the compaction plate is matched with the trowelling plate to compact the concrete, meanwhile, a first elastic plate buffers the concrete through the spring in a buffer block, compaction buffering of the concrete is achieved, and the situation that formingof the concrete is affected due to an excessive stress is avoided.

Description

technical field [0001] The invention relates to the technical field of bridge pier repair, in particular to a construction method for concrete bridge pier repair. Background technique [0002] Concrete pavement refers to the pavement with cement concrete slab as the surface layer. It refers to the pavement structure composed of cement concrete slab as the surface layer, base layer and cushion layer, also known as rigid pavement; [0003] The bridge pier is a substructure that supports the bridge span structure and transmits the dead load and vehicle live load to the foundation. In addition to supporting the bridge span structure, it also needs to connect with the embankment and prevent the embankment from slipping. In order to protect the embankment and embankment filling, some protection and diversion projects are often done on both sides of the embankment; [0004] Due to the long-term effect of the external environment on concrete bridge piers, the material will age, or ...

AI Technical Summary

Problems solved by technology

[0005] (1) Since the pier needs to be cut when filling, the pier is vertical after the cut, so it is easy to make the injected concrete flow out when pouring concrete, and it is not easy to inject;

[0006] (2) The concrete injected into the incision cannot be compacted and troweled simultaneously, and when the concrete is compacted, due to excessive force, it is easy to cause the molding effect of the concrete;

[0007] (3) Since the sides of some bridge piers are inclined to the ground, it is impossible to smooth and compact the injected concrete;
