Embodiment Construction

[0019] In order to further illustrate the technical means and functions adopted by the present invention to achieve the intended purpose, the specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0020] like Figure 1~3 A structural schematic diagram of the structure jacking device of the present invention is shown, including a bolt 1 , a body 2 , a support rod 3 , a groove 4 and a through hole 5 . In a preferred embodiment, the body 2 is a cylindrical structure, and a through hole 5 is provided at the center of the body 2 of the cylindrical structure. The through hole 5 is used to place the bolt 1 and its size is slightly larger than that of the bolt 1 to match it. The inner surface of the through hole 5 is provided with threads.

[0021] In order to facilitate the body 2 to be stressed at the construction position, four grooves 4 are uniformly arranged on the lower surfac...

Abstract

The invention discloses a structure jacking device. The structure jacking device comprises a bolt and a body, wherein the body adopts a cylindrical structure with a through hole in the center, the bolt is arranged in the through hole, the size of the bolt is matched with the through hole, and threads are formed in the inner surface of the through hole. The structure jacking device is mainly used for overcoming defects of high requirements of current jacking engineering, time consumption and labor consumption, can be used for performing jacking operation in a smaller place, requires fewer conditions and can conveniently perform jacking operation.

Description

technical field [0001] The invention relates to a device for engineering construction, in particular to a subsidence road surface capable of lifting small volumes, and a mountainous road surface that is difficult to enter for large-scale projects. Background technique [0002] With the rapid development of road engineering, the repair and maintenance of roads requires a lot of manpower and material resources to complete. For locations with relatively good construction conditions, construction machinery is used to complete them. However, for mountainous areas or parts with difficult road conditions, huge It is very difficult for the construction machinery to be transported to the construction site, causing inconvenience to the construction. Most of the road surface and bridge deck jacking require the cooperation of engineering vehicles and professionals, and a large construction space is required for construction under the road surface and bridge deck, and some smaller ones s...
