Ground support supporting structure with rib groove

Abstract

The invention relates to a ground support supporting structure with a ribbed groove. The ground support supporting structure is a front-placed ground support arranged in the set depth of a soil body in a foundation pit in the horizontal direction before a foundation pit earthwork is excavated, one end of the ground support supports a retaining pile wall, the ground support is formed by construction equipment propelling in the horizontal direction, a column reinforced body with the preset cross section is formed in the set depth in the soil body through the construction equipment, the ribbed groove is formed between the top surface of the reinforced body and the terrace of a site, the length of the ribbed groove is equal to that of the reinforced body, cement soil slurry in the rib groove forms a ribbed plate after solidification, a rigid blocking is arranged at the end, away from the retaining pile wall, of the ground support, a vertical reinforced body is arranged on the lower part ofground support, and a rear-placed inclined support is arranged on the upper part of the ground support. According to the ground support structure with the ribbed groove, supporting and pit bottom reinforcing can be integrated into a whole, the engineering cost is lowered, earth cutting and construction are convenient, the construction period is shortened, thus the economic benefit is brought, andthe ground support structure with the ribbed groove has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to the technical field of foundation pit engineering, in particular to a ground support structure with ribbed grooves. Background technique [0002] As a temporary or permanent technical measure, foundation pit support (or foundation pit enclosure) occupies an important part of the construction cost, especially in soft soil areas, the cost of foundation pit support is higher. Reducing the cost of foundation pit support is the unremitting pursuit of engineers and technicians in the construction industry. In the traditional foundation pit support technology, the slab enclosure structure that directly retains soil and water includes various sheet piles, column pile walls, steel cement-soil diaphragm walls (or SMW piles), underground diaphragm walls and other slab piles. Enclosure pile walls, etc., according to different engineering conditions, this type of enclosure structur...

AI Technical Summary

Problems solved by technology

However, when the area or side length of the foundation pit is large, the cost of support is more prominent in the traditional inner support (flat support) form, especially for not very deep foundation pits, the cost of support plus columns and column piles is just appear inappropriate, in this case, the diagonal brace and other new types of diagonal braces are a better choice to solve this problem

However, diagonal braces also have disadvantages such as affecting excavation, prolonging the construction period, and limiting the site.
