Abstract

The invention discloses a pier column reinforcing and support replacing device. A bearing platform is arranged on the periphery of a pier column; a sleeve sleeves the pier column and is supported at the top of the bearing platform, and concrete is arranged between the sleeve and the pier column; and a jacking assembly is used for being installed between the bridge body and the sleeve, the jacking assembly can jack the bridge body to replace the support, and the bridge body is lowered after the support is replaced so that the bridge body can be supported on the support. According to the pier column reinforcing and support replacing device in the technical scheme, pier column reinforcing and support replacing are combined, the erecting work of a temporary support is omitted, the support replacing efficiency is greatly improved, the bridge and culvert maintenance progress is accelerated, meanwhile, the cost for erecting the temporary support can be reduced, and the cost is saved.

Description

technical field [0001] The invention is used in the technical field of bridges, and in particular relates to a pier column reinforcement and support replacement device. Background technique [0002] In recent years, with the vigorous development of our country's traffic, bridges and culverts, as a key component of traffic, play a very important role in traffic. Due to the long history of construction of most bridges and culverts, the problems of structural durability and bearing capacity have gradually become prominent under the repeated action of large and overweight vehicles. As the main force-bearing components of the structure, pier columns and supports face problems such as aging and misalignment, and their safety affects the overall situation. Therefore, it is necessary to strengthen the long-used pier columns and replace the old supports with new ones. seat. [0003] Currently, the construction process for replacing the bearings and strengthening the piers is carrie...
