Background
In the engineering construction process, for large foundation pits, especially those with harsh surrounding environments, a foundation pit supporting form with an inner support is often adopted, and a cast-in-place reinforced concrete inner support is mostly adopted. The length and the width of the large foundation pit are both larger, so that the span of the inner supporting beam is also larger, and in order to prevent the horizontal inner supporting beam from generating excessive bending deformation, a vertical supporting column is required to be arranged at a proper position. The common vertical support column is a lattice column, a support strut is required to be arranged below the beam at the joint of the vertical support column and the horizontal support beam, and the support strut is generally composed of a plurality of steel plates and is welded on the lattice column below the horizontal support beam. Because the size of the supporting brace is large, the supporting brace is required to be arranged below the horizontal supporting beam, and the requirement on the vertical position is strict, the supporting brace cannot be welded in advance before the lattice column is installed on the cast-in-place pile, and the supporting brace can only be welded on the lattice column before the earth excavation is carried out in place and the horizontal supporting beam is constructed. Because the beam bottom of the horizontal supporting beam is positioned on the earthwork excavation surface, and the beam bottom die is directly laid on the original soil, in order to weld the support, a welding worker has a welding operation space, a deep pit needs to be dug at the periphery of the lattice column firstly, the worker stands in the pit, the deep pit is backfilled after the welding is finished, and the horizontal supporting beam is tamped in layers without filling, so that the uneven sinking at the periphery of the lattice column can be avoided when the horizontal supporting beam is cast with concrete.
Therefore, the conventional lattice column support construction is complicated, if the number of the lattice columns is large, the workload of earth excavation and backfilling is large, if the soil quality is poor (such as silt soft soil), a working pit at a single node needs to be placed on a slow slope, the total excavation and backfilling amount is large, and due to the fact that the space is narrow and small, mechanical operation cannot be conducted, only manual excavation and backfilling can be conducted, and the backfilling quality is not easy to guarantee.
