Abstract

The invention belongs to the technical field of bridge supports and discloses a height adjustment support and a technique for utilizing the height adjustment support to adjust height. The invention has the main technical characteristics that the height adjustment support comprises an upper seat plate, a rubber bearing plate and a base basin; the base basin is provided with injection agent pipelines with a valve; the injection agent pipelines are connected with an injection-moulding machine by a check valve, a throttle and a flow divider; the injection agent pipelines are internally poured with bicomponent polyurethane rubber are two or more than two; and the injection-moulding machine is connected with a hydraulic sensor. The height adjustment support can lead the height of the girder to reach conformity or meet design requirements by adjusting the height, can adjust height in a stepless and multiple times manner, can measure load force, has simple and convenient construction in the processes of leveling, measuring force and adjusting height, does not need large machines and other jacking equipment and can adjust height with dynamic load.

Description

technical field [0001] The invention belongs to the technical field of bridge supports, and in particular relates to a height-adjusting support and a height-adjusting process using the same. Background technique [0002] With the continuous increase of domestic infrastructure construction projects, the proportion of various bridge and aqueduct structures in infrastructure construction continues to increase. In the case of uneven settlement of the foundation of the beam body, the stress state of the upper and lower structures will be changed, which will bring hidden dangers to the safety of the structure. In addition, due to the unavoidable construction errors of the supporting pad stone elevation of the beam structure, the slight deformation of various prefabricated beams and continuous beam structures after tensioning, and the allowable height error after the bridge support is processed, various bridges 1. During the construction of the aqueduct structure, there is an unav...
