Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0030] like Figure 1 to Figure 7 shown.
[0031] A support system for a deep foundation pit, comprising a steel support 4, a chute 3, a single-sided sliding block 5 and a double-sided sliding block 2.
[0032] The chute 3 is in the shape of a long straight plate, and its two side edges are provided with opposite inverted L-shaped ribs, forming a guiding groove I301.
[0033] The single-sided slider 5 is in the shape of a rectangular block, and its bottom surface is provided with a bump I501 whose end face is in the shape of a "convex"; the large end of the bump I501 can be embedded in the groove I301, so that the single-sided The slider 5 can move along the chute 3; the end surface of the single-sided slider 5 is provided with a support 6, which can strengthen the support of the middle part of the steel support 4. Preferably, the support member 6 is...

The invention relates to a deep foundation pit supporting system which comprises a steel support, a sliding groove, a single-side sliding block and a double-side sliding block. The sliding groove is in the shape of a strip straight plate, and the edges of two sides of the sliding groove are provided with opposite inverted L-shaped ridges to form a groove I capable of guiding; the single-side sliding block is a rectangular block, and the bottom surface of the single-side sliding block is provided with a convex block I with a convex shape on the end face; the double-side sliding block is a rectangular block, the bottom surface of the double-side sliding block is provided with a convex block II with a convex shape on the end face, the two side edges of the top surface of the double-side sliding block are provided with opposite inverted L-shaped convex ridges, and a groove II capable of guiding is formed; a front-back through hole is formed in the double-side sliding block; a movable cushion block is arranged in the through hole; the sliding groove and the double-side sliding block are combined and then installed on the side wall of a foundation pit, and the sliding groove and the single-side sliding block are combined and then installed on a lattice column; and a limiting structure is arranged on the sliding groove and can limit the movement of the single-side sliding block or thedouble-side sliding block. The deep foundation pit supporting system can realize the non-planar sliding of the steel support in the vertical direction.
Description
technical field [0001] The invention relates to a building component, in particular to a support system for open-cut foundation pits, in particular to a deep foundation pit support system. Background technique [0002] At present, open excavation foundation pits, especially deep foundation pits, need to use steel support systems to support their side walls during the excavation process to prevent them from collapsing. When the support part needs to be replaced, it is usually necessary to hoist and remove the original steel support in sections, readjust the length of the steel support, and then hoist and assemble in sections. This method not only needs to occupy large-scale hoisting equipment for a long time, but also has a series of disadvantages such as complicated procedures, long construction period, and difficulty in protecting the upper steel support and concrete support. Therefore, there is an urgent need to develop a new steel support system to solve the above proble...
