Problems solved by technology

[0002] During the construction process, it is unavoidable to encounter some shallow buried buildings, which need to be constructed after excavation. At the same time, the surrounding environment is limited, and slope excavation cannot be adopted, and only vertical excavation can be carried out.
If the conventional construction method is adopted, the steel sheet piles are rented out, and the steel sheet piles are supported on site, but the number of leased steel sheet piles is small, the construction period is long, and the cost is high

Embodiment

[0016] refer to figure 1 and figure 2 , this embodiment provides a simple shallow foundation pit support system, including I-beams 1 distributed along the circumference of the foundation pit, and the I-beams 1 are all arranged vertically. The distance is 1m, and the I-beams 1 are connected and reinforced by the I-beam purlins 4. The I-beam purlins 4 are arranged along the horizontal direction. The distance between the I-beam purlins 4 and the upper end of the I-beam 1 is 1m. The I-shaped steel purlins 4 are reinforced and connected by I-shaped steel diagonal braces 5, and I-shaped steel straight braces 6 are arranged between the oppositely arranged I-shaped steel purlins 4, and the two ends of the I-shaped steel straight braces 6 are welded and fixed on the opposite On the two I-shaped steel purlins 4 set, a steel plate 2 arranged vertically is arranged between two adjacent I-shaped steels 1, the thickness of the steel plate 2 is 10mm, and the two sides of the steel plate 2 ...

Abstract

The invention provides a simple shallow foundation pit support system and a construction method. The simple shallow foundation pit support system comprises I-shaped steel, wherein the I-shaped steel is distributed in the circumferential direction of a foundation pit, the I-shaped steel is arranged in the vertical direction, the I-shaped steel is connected and reinforced through I-shaped steel purlins, steel plates are vertically arranged between every two adjacent I-shaped steel, both sides of the steel plates are respectively arranged in I-shaped steel grooves in both sides, steel groove limiting blocks are respectively welded to both sides of a web of the I-shaped steel, and the both sides of the steel plates are respectively clamped between the steel groove limiting blocks and wing plates of the I-shaped steel. The simple shallow foundation pit support system aims to solve the problems that rented steel sheet piles need to be supported, the number of rented steel sheet piles is small, the construction period is long, and the cost is high in an existing conventional vertical excavation construction method. The simple shallow foundation pit support system belongs to the field of building foundation pit construction.

Description

technical field [0001] The invention relates to a simple shallow foundation pit support system and a construction method, which is particularly suitable for the case where the excavation depth of the foundation pit is less than 3m, and belongs to the field of building foundation pit construction. Background technique [0002] During the construction process, it is inevitable that some buildings with shallow burial will be encountered, which need to be excavated before construction. At the same time, the surrounding environment is limited, and slope excavation cannot be adopted, and only vertical excavation can be carried out. If the conventional construction method is adopted, the steel sheet piles are rented out, and the steel sheet piles are supported on site, but the number of leased steel sheet piles is small, the construction period is long, and the cost is high. Therefore, it is imperative to design a kind of material and equipment that does not need to be rented out, ...
