Problems solved by technology
[0008] The construction of the anchor support structure is difficult, the construction cost is high, and the bearing capacity is highly discrete
[0009] The cantilever support structure is very sensitive to the excavation depth, and it is prone to large deformation, which will have adverse effects on the surrounding environment
[0010] The inner support structure affects the construction of the main structure, affects the construction period and cost, and the construction cost is large, and the deformation after construction is large

The invention discloses a foundation pit support structure and a construction method thereof, wherein the foundation pit support structure comprises a lattice wall, a slope cutting stereobate, an inner support beam, a main body structure, and a foundation slab arranged on the bottom part of a foundation pit; the lattice wall and the slop cutting stereobate are orderly attached to the inner wall of the foundation pit; the inner support beam is arranged above the slope cutting stereobate; one end of the inner support beam is connected with the side of the lattice wall, and the other end of the inner support beam is connected with the main body structure. An earth cutting mode of a'center island' method is combined with the lattice wall to ensure water stopping and displacement control of the foundation pit when the foundation pit support structure is constructed, so the reliability of the foundation pit support structure is improved, the construction is simple, the work period is short and the economical efficiency is strong.
Description
technical field [0001] The invention relates to the field of building foundations, in particular to a foundation pit support structure and a construction method thereof. Background technique [0002] my country's rivers and seas are widely distributed, and a lot of soft soil and sand strata were deposited in ancient times. Now these regional economies are basically developed, and engineering activities continue to expand underground, especially large and deep foundation pits. many. The key factors in the design of large-scale foundation pits in soft soil and sandy strata are the selection of enclosure methods and excavation methods. Therefore, choosing an economical, reasonable, safe and reliable foundation pit support method is to control the overall stability of the foundation pit and the deformation of the foundation pit. the key to. [0003] Existing foundation pit support structures include row pile support structure, cement mixing pile gravity support structure, steel...
