Description

Technical Field

[0001] The utility model relates to a stress system for dispersing the side load of an elevator shaft foundation pit, belonging to the technical field of building construction. Background Technique

[0002] When excavating an elevator shaft foundation pit under a silt foundation, in order to resist the inward pressure of the silt flow and collapse, it is necessary to first enclose the silt foundation by driving sheet piles. After the excavation of the elevator shaft foundation pit is completed, due to environmental factors such as rainwater, some sheet piles will be squeezed by the silt and inclined into the foundation pit. During subsequent construction, it is necessary to straighten the sheet piles inclined into the foundation pit.

[0003] Since the sheet piles enclose the elevator shaft foundation pit, it is inconvenient for the excavator to walk in and carry out the straightening construction. When referring to the steel support for straightening the sheet piles (see the Chinese patent publication number CN219568906U), straightening is carried out based on the single sheet pile in the opposite direction, and there is a problem that the single point of the sheet pile to be straightened is subjected to too much force and deforms. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a stress system for dispersing the side load of an elevator shaft foundation pit.

[0005] The utility model is realized through the following technical solutions.

[0006] A stress system for dispersing the side load of an elevator shaft foundation pit provided by the utility model includes:

[0007] Sheet piles;

[0008] Support beam A and support beam B, support beam A and support beam B are rotatably hinged;

[0009] Support beam A correspondingly supports multiple sheet piles through multiple spaced support blocks;

[0010] Support beam B correspondingly supports multiple sheet piles through multiple spaced support blocks B;

[0011] The multiple sheet piles supported by multiple support blocks A and the multiple sheet piles supported by multiple support blocks B are in opposite directions.

[0012] It further includes a silt foundation. The sheet piles are alternately distributed and buckled with each other in the silt foundation to form an enclosure area, and a concave space is formed inside the sheet piles to form an elevator shaft foundation pit.

[0013] The support beam A is fixed with a force dividing plate A, and a plurality of telescopic members A with a plurality of numbers are fixedly connected to the support blocks A correspondingly on the force dividing plate A, and the plurality of support blocks are spaced apart to correspondingly support the sheet piles for multiple supports.

[0014] The supporting beam B is fixed with a component force plate B, and a plurality of telescopic members B are provided on the component force plate B and fixedly connected to the supporting blocks B correspondingly. The plurality of supporting blocks B are spaced apart to support the steel sheet piles at multiple points.

[0015] The beneficial effects of the present utility model are as follows: A plurality of component force plates A and a plurality of component force plates B obtain a force-bearing basis by contacting the steel sheet piles at multiple points, so that the pressure load generated by the silt foundation on the side of the elevator shaft foundation pit is dispersed, realizing the straightening of the inclined steel sheet piles, and solving the problem that the single-point force on the steel sheet piles to be straightened is too large and causes deformation.

Detailed Embodiments

[0019] The technical solution of the present utility model will be further described below, but the scope of protection is not limited thereto.

[0020] As Figures 1 to 2 shown.

[0021] A force-bearing system for dispersing the load on the side of the elevator shaft foundation pit of the present application includes:

[0022] A plurality of steel sheet piles 1, the steel sheet piles 1 are alternately distributed and buckled with each other in the silt foundation 2 to form an enclosed area, and a concave space is formed inside the steel sheet piles 1 to form an elevator shaft foundation pit 11.

[0023] In the space of the elevator shaft foundation pit 11, a supporting beam A 3 and a supporting beam B 4 that can be rotatably hinged to each other are installed.

[0024] The supporting beam A 3 is fixed with a component force plate A 31, and a plurality of telescopic members A 32 are provided on the component force plate A 31 and fixedly connected to the supporting blocks A 33 correspondingly. The plurality of supporting blocks A 33 are spaced apart to support the steel sheet piles 1 at multiple points.

[0025] The supporting beam B4 is fixed with a force dividing plate B41. A plurality of telescopic members B42 are provided on the force dividing plate B41, and the supporting blocks B43 are fixedly connected correspondingly. The plurality of supporting blocks B43 are spaced apart to support the steel sheet piles 1 at multiple positions; the plurality of supporting blocks A33 and the plurality of supporting blocks B43 support the plurality of steel sheet piles 1 in opposite directions.

[0026] For example, when a certain steel sheet pile 1 inclines into the elevator shaft foundation pit 11, the force dividing plate A31 on the telescopic member A32 is controlled to support the inclined steel sheet pile 1 itself and the adjacent steel sheet pile 1, and the force dividing plate B41 on the telescopic member B42 is controlled to support the plurality of steel sheet piles 1 opposite to the steel sheet pile 1 to be righted. The plurality of telescopic members A32 and the plurality of telescopic members B42 are controlled to extend by different lengths and push against the steel sheet pile 1, so that the plurality of force dividing plates A31 and the plurality of force dividing plates B41 contact the plurality of steel sheet piles 1 to obtain a force-bearing basis, and the pressure load generated by the silt foundation 2 on the side of the elevator shaft foundation pit 11 is dispersed, realizing the righting of the inclined steel sheet pile 1 and solving the problem that the single point of the steel sheet pile to be righted is subjected to too much force and deforms.

[0027] A construction method for dispersing the load on the side of the elevator shaft foundation pit of the present application includes:

[0028] The plurality of force dividing plates A31 and the plurality of force dividing plates B41 support the plurality of steel sheet piles 1 in opposite directions, constructing a force-bearing system for dispersing the load on the side of the elevator shaft foundation pit.

[0029] The plurality of telescopic members A32 and the plurality of telescopic members B42 are controlled to extend by different lengths and push against the steel sheet pile 1, and the force is transmitted between the support beam A3 and the support beam B4 which are rotatably hinged to each other, so that the plurality of force dividing plates A31 and the plurality of force dividing plates B41 contact and bear force on the plurality of steel sheet piles 1. When the inclined steel sheet pile 1 is righted, the pressure load generated by the silt foundation 2 on the side of the elevator shaft foundation pit 11 is dispersed to the plurality of steel sheet piles 1.
