[0002] In industrial production, some factory buildings are often used as warehouses for storing raw materials such as lithium ore, sand and gravel. The raw material yard has a large load and is uncertain and uneven. Due to its special functional requirements, the upper part of this type of factory building is often a portal frame structure with steel columns resting on concrete structural columns. The lower part of the factory building should be designed as a concrete retaining wall structure that can stack loose raw materials of a certain height.

[0003] The retaining wall structure is usually set up continuously around the factory building, and it is easy to collide with the factory building's structural columns. There are usually two ways to solve the problem of retaining wall and structural column collision: one is to design the retaining wall and structural column together, bear the force together, and cast the whole structure for construction. This method is complicated in structural force calculation, and when the retaining wall is damaged, it will affect the safety of the main structure of the factory building; the other is to separate the structural column from the retaining wall, and the column foundation falls directly on the ground, set an independent foundation, and place the retaining wall foundation under the independent foundation. The retaining wall body is set outside the short column. This method will lead to the additional occupation of the steel column in the factory building space and the increase of consumables, resulting in an increase in construction costs. Summary of the invention

[0004] The utility model aims to solve the deficiencies of the prior art and provides a disengagement structure at the collision point between a retaining wall and a factory building structural column.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a disengagement structure at the collision point between a retaining wall and a factory building structural column, comprising a retaining wall, a retaining wall foundation, a structural column, and a structural column foundation. A structural column foundation cushion layer is arranged at the bottom of the structural column foundation, the structural column is arranged at the top of the structural column foundation, a crushed stone cushion layer is arranged at the top of the structural column foundation, a plurality of structural columns are arranged in the retaining wall, the retaining wall and the structural column are at the same height, the retaining wall and the structural column facade are vertically flush, and a vertical deformation joint is arranged between the retaining wall and the side wall in the longitudinal direction of the structural column, an extruded plate is arranged in the vertical deformation joint, a retaining wall foundation cushion layer is arranged at the bottom of the retaining wall foundation, the retaining wall is arranged at the top of the retaining wall foundation, a cam is arranged at the bottom of the retaining wall foundation, a cam groove matching the cam is arranged on the retaining wall foundation cushion layer, the cam is inserted in the cam groove, the retaining wall foundation cushion layer is arranged at the top of the crushed stone cushion layer, a cam groove matching the cam groove is arranged on the top of the crushed stone cushion layer, and the cam groove is embedded in the cam groove.

[0006] In particular, the retaining wall foundation is a strip foundation, and the structural column foundation is an independent foundation or a pile cap foundation.

[0007] In particular, the crushed stone cushion layer covers the entire top surface of the structural column foundation, has a laying thickness of 300-500mm, and is filled with a slope of 45 degrees upward from the top edge of the structural column foundation.

[0008] In particular, the width of the vertical deformation joint is 30 mm.

[0009] Particularly, the structural column comprises a lower end column and an upper end column, the lower end column being 900-1200 mm higher than the top of the structural column foundation and 300-500 mm higher than the top of the retaining wall foundation.

The retaining wall foundation 2 is a strip foundation, and the structural column foundation 4 is an independent foundation or a pile cap foundation. The bearing capacity after foundation treatment meets the design requirements. The structural column 3 comprises a lower end column 301 and an upper end column 302. The lower end column 301 is 900-1200mm higher than the top of the structural column foundation 4, and 300-500mm higher than the top of the retaining wall foundation 2.

[0019] A structural column foundation cushion layer 5 is arranged at the bottom of the structural column foundation 4, the structural column 3 is arranged at the top of the structural column foundation 4, a crushed stone cushion layer 6 is arranged at the top of the structural column foundation 4, a retaining wall foundation cushion layer 8 is arranged at the bottom of the retaining wall foundation 2, the retaining wall 1 is arranged at the top of the retaining wall foundation 2, a cam 201 is arranged at the bottom of the retaining wall foundation 2, a cam groove 801 matching the cam 201 is arranged on the retaining wall foundation cushion layer 8, the cam 201 is plugged into the cam groove 801, the retaining wall foundation cushion layer 8 is arranged on the top of the crushed stone cushion layer 6, a cam groove 601 matching the cam groove 801 is arranged on the top of the crushed stone cushion layer 6, and the cam groove 801 is embedded in the cam groove 601; the crushed stone cushion layer 6 covers the entire top surface of the structural column foundation 4, the laying thickness is 300-500mm, and is filled with a slope of 45 degrees upward from the top edge of the structural column foundation 4.

[0020] Specifically, at the place where the retaining wall 1 and the structural column 3 collide, the buried depth of the structural column foundation 4 is increased, and at the top of the structural column foundation 4, a 300-500mm thick crushed stone cushion layer 6 is filled in the overlapping area of ​​the vertical projection of the retaining wall foundation 2 and the structural column contact 4, and the retaining wall foundation 2 is arranged on the crushed stone cushion layer 6, and a tenon 201 is arranged on the bottom of the retaining wall foundation 2, so as to improve the anti-slip stability of the retaining wall 1;

[0021] A number of structural columns 3 are arranged in the retaining wall 1. The retaining wall 1 is at the same height as the structural columns 3.
