A reinforcement operating device for bridge maintenance

Abstract

The invention relates to the technical field of bridges, in particular to a reinforcing operation device for bridge maintenance. The reinforcing operation device comprises a base, a first retractablemechanism and a lifting frame; the upper surface of the base is fixedly connected with the first retractable mechanism, the top of the first retractable mechanism is fixedly connected with the liftingframe, a bidirectional screw rod is mounted in the lifting frame, an upper sliding block and a lower sliding block sleeve the bidirectional screw rod, an upper reinforcing device is mounted on the side wall of the upper sliding block, and a lower reinforcing device is mounted on the side wall of the lower sliding block. A plurality of retractable supporting rods are uniformly distributed on the upper surface of the lower reinforcing device, and the upper reinforcing device and the lower reinforcing device are arranged to fix bridge pillars so as to play a role in reinforcing the bridge pillars; the retractable supporting rods are utilized to play a role in reinforcing and supporting, so that the stability of the bridge pillars is further improved. The reinforcing operation device has theadvantages that the supporting effect is great, the stability is high, the safety is further improved, and stirring plates are utilized to stir grouting resin glue so that the grouting resin glue canbe turned up and down in a material filling box and prevented from being deposited.

Description

Technical field [0001] The invention relates to the technical field of bridges, and more specifically, to a strengthening operation device for bridge maintenance. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the rapid development of the modern transportation industry, bridges are also extended to cross mountain streams, poor geology or to meet other transportation needs and erected to make traffic more convenient. A bridge generally consists of an upper structure, a lower structure, supports and auxiliary structures. The upper structure is also called a bridge span structure, which is the main structure that spans obstacles; the lower structure includes abutments, piers and foundations; the supports are bridge span structures and piers Or the force transmission device installed in the supporting place of the bridge abutment; the ancillary structure r...

Problems solved by technology

[0003] Bridges play a huge role in the internal traffic system of the city. Bridge buildings such as viaducts and pedestrian bridges are very common. However, after long-term use, the bridge pillars are prone to cracks and their strength is reduced. It is necessary to reinforce the bridge pillars and grout the cracks. Now Some bridge repair and reinforcement devices have poor reinforcement effects, and the grouting resin glue is prone to precipitation
