AI Technical Summary
Technical Problem
Existing foundation pit support devices suffer from uneven stress due to unilateral support, making it difficult to ensure support stability.
Method used
A foundation pit support device including a first support mechanism and an anchoring connection mechanism is adopted. By setting symmetrical load-bearing plates on both sides of the foundation pit and anchoring them into the soil using the anchoring connection mechanism, opposing support is formed to ensure balanced force.
Benefits of technology
It achieves balanced stress on both sides of the foundation pit, improves support stability, enhances support strength and construction flexibility, and adapts to the needs of foundation pits of different depths and working conditions.

Abstract
The application relates to a foundation pit supporting technology field, and provides a foundation pit supporting device and a supporting method. The device comprises a first supporting mechanism and an anchoring connecting mechanism. The first supporting mechanism comprises two stress plates arranged oppositely. The anchoring connecting mechanism comprises an anchoring assembly and a connecting assembly. The anchoring assembly comprises a supporting rod, at least two side rods and a top rod. The supporting rod is arranged on the stress plate and is used for being inserted into the foundation pit. Each side rod is rotationally arranged on the supporting rod. The top rod is movably arranged on the supporting rod. The movement of the top rod drives each side rod to rotate, so that the side rod is anchored in the foundation pit. The connecting assembly connects the two top rods. The two stress plates are arranged on the soil bodies on the two sides of the foundation pit respectively, so as to bear the lateral pressure of the soil bodies. The two stress plates are connected by the anchoring connecting mechanism and are anchored in the soil bodies of the foundation pit, so that the two stress plates on the two sides of the foundation pit form opposite supports, the stress balance on the two sides of the foundation pit is ensured, and the supporting stability is improved.
