[0001] The utility model relates to the technical field of building construction, and more specifically to a foundation pit oblique support structure. Background Art

[0002] During the construction process, in order to protect the safety of the underground main structure construction and the surrounding environment of the foundation pit, foundation pit support is an indispensable temporary support, reinforcement, protection and groundwater control measure in the construction and implementation of underground projects. However, the foundation pit inclined support structure can only support the retaining piles and can only support their upper end, which reduces the support effect and support stability.

[0003] For example, announcement No. CN220598449U discloses a foundation pit inclined brace support structure, which includes a waist beam, an inclined brace and an inclined brace support foot connected in sequence, wherein the waist beam is fixedly connected to the upper part of the retaining pile, and an inclined brace short pile foundation is provided at the lower part of the inclined brace support foot, and the inclined brace short pile foundation is fixedly arranged inside the foundation pit.

[0004] It can be seen from the above-mentioned public scheme that the inclined brace is set between the waist beam and the inclined brace support foot, and the waist beam is connected to the side of the upper end of the retaining pile, so that the inclined brace can only support the upper end of the retaining pile, and its lower end cannot be supported, which may cause the retaining pile to deform and fall, reducing the supporting strength, and the inclined brace cannot be set between two adjacent retaining piles, making it impossible to support the soil on the inner wall of the side of the foundation pit, which will cause the soil to fall into the foundation pit, reducing the support effect.
