Description

Technical Field

[0001] The invention relates to an oblique bracing device, more specifically to an oblique parapet bracing device for a central island of a deep foundation pit. Background Art

[0002] With the acceleration of my country's urbanization process, the development and utilization of underground space has developed rapidly, and foundation pit projects have become more and more common. As a result, the structure of foundation pit retaining walls and the implementation process have continued to develop. Foundation pit projects are temporary retaining walls that only take effect during the basement excavation stage. Therefore, it is generally necessary to comprehensively consider factors such as the surrounding environment, structural safety, project cost, construction convenience and construction period. Traditional foundation pit retaining projects include gravity type, cable-stayed type, parallel support type, inclined support type, etc. The inclined support type is a theoretically very reliable foundation pit retaining structure because a triangular structure is formed between the inclined support, retaining wall and the ground. However, it is not very reliable in actual construction. Usually, a retaining wall is first driven into the soil, and then a pit is dug on one side of the retaining wall. A corbel support point is made in the excavated space, and an inclined brace is installed between the corbel support point and the retaining wall by cast-in-place or welding to form a foundation pit enclosure. The existing inclined brace has a fixed angle position of the support rod. When fixing it on the ground, it is often necessary to consider the position of the ground and the softness and flatness of the soil. It requires manual grinding and pouring, which is more troublesome, and in order to achieve the specified angle position, it needs to be adjusted repeatedly many times. Summary of the invention
