Assembly type box transformer substation foundation and field construction method thereof

Abstract

The invention belongs to the field of box-type transformer substation foundations, and discloses an assembly type box transformer substation foundation and a field construction method. The assembly type box transformer substation foundation comprises bottom plates, stand column bases, stand columns, connecting steel plates, connecting bolts and the like; and due to the design of six modular bottomplates, when box-type transformer substation with different sizes need to be adapted, only the modular bottom plates need to be added or expanded in the form of removal. When the box-type transformersubstation foundation needs to be shifted, only the foundation soil needs to be dug out, the welding part of the box-type transformer substation and the box-type transformer substation foundation iscut off, then the box-type transformer substation foundation is integrally disassembled and can be put into the next engineering for use. The method has the advantages of being reasonable in structure, clear in force transmission path, simple to assemble, short in construction period, low in manufacturing cost, capable of being repeatedly used, suitable for box-type transformer substations with various specifications, small in environmental disturbance and the like.

Description

technical field [0001] The invention belongs to the field of box-type substation foundations, and more specifically relates to a prefabricated box-type substation foundation and an on-site construction method thereof. Background technique [0002] At present, most of the foundations of box-type substations are built using the cast-in-place construction method. The cast-in-place box-type foundation has the following disadvantages: [0003] 1) The construction period is long. The cast-in-place box substation foundation requires on-site binding of steel bars, on-site formwork, on-site pouring of concrete, and later formwork removal, etc., and the construction period is long; [0004] 2) The cost is high, and it will cost more to excavate the foundation, bind the steel bars, make the mold, pour the concrete, maintain the concrete, and dismantle the formwork; [0005] 3) It has a great impact on the environment. The foundation of the box-type substation is often built in the cit...

AI Technical Summary

Problems solved by technology

[0003] 1) The construction period is long. The cast-in-place box substation foundation requires on-site binding of steel bars, on-site formwork, on-site pouring of concrete, and later formwork removal, etc., and the construction period is long;

[0004] 2) The cost is high, and it will cost more to excavate the foundation, bind the steel bars, make the mold, pour the concrete, maintain the concrete, and dismantle the formwork;

[0005] 3) It has a great impact on the environment. The foundation of the box-type substation is often built in the city. The excavation of the foundation soil will inevitably affect the urban environment and the image of the city. The construction period of the cast-in-place box-type substation often takes one month or more. For The urban environment has a greater impact, affecting normal travel

[0006] At present, there are few inventions for the prefabricated box-type foundation. The existing prefabricated box-type substation foundation structure design is unreasonable, the structural force transmission path is not appropriate, the integrity and stability are poor, and in the prefabricated box-type substation foundation assembly The use of post-cast concrete leads to the non-reusable foundation of the prefabricated box-type substation, long construction period, and high cost. These unfavorable factors limit the application and promotion of the prefabricated box-type substation foundation
