For a building foundation pit, construction investment cost accounts for relatively less total engineering cost, structures of water conservancy and water environment improvement facilities such as an underground storage tank and the like are relatively simple, the construction investment cost accounts for relatively more total engineering cost, and the problem of resource and fund waste caused by dismantling an enclosure structure after construction is completed is more prominent.
The integrated supporting structure of the foundation pit is a design and construction method for combining a support structure with an underground single structure, namely the support structure of the foundation pit is also used as a part of the underground single structure in a permanent use stage to bear part of load.

However, the beam steel bars have large diameters and are densely distributed, so that the beam steel bars are difficult to avoid colliding with the lattice column batten plate. In addition, at the crossed nodes of the plurality of cross beams, the main reinforcements and the stirrups are distributed too densely to bring certain difficulty to concrete pouring and vibrating.
Based on the situation, the utility model provides an integrated lattice column structure suitable for an underground single structure and a foundation pit support structure, and the problems can be effectively solved.
