Abstract

The invention relates to a fabricated lattice unit for foundation pit supporting. The fabricated lattice unit for foundation pit supporting is characterized by comprising a plurality of lattice unit bodies which are connected through connecting structures, each lattice unit body comprises a middle column and beams arranged on the side walls of the periphery of the middle column and evenly distributed, each middle column is provided with an anchor cable hole and is connected with an anchor cable on a foundation pit through the anchor cable hole, and every two adjacent lattice unit bodies are connected through the connecting structures at the ends of the corresponding beams. Each connecting structure is composed of fixing bolts arranged at the ends of the corresponding beams and connecting plates, and through holes matched with the fixing bolts are formed in the connecting plates. The fabricated lattice unit for foundation pit supporting can be well adapted to a hard clay stratum or a mud rock stratum or other stratums, and the supporting effect of the fabricated lattice unit is reliable; construction is safe and rapid, no large machine is needed, and the prefabricated lattice unit has the advantages of being dismountable and recyclable; industrial and standard production can be achieved. By the adoption of the fabricated lattice unit for foundation pit supporting, consumption of energy resources can be reduced, labor productivity is improved, and environment protection is promoted.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering foundation pit support. Background technique [0002] With the rapid development of the urban economy, there are more and more high-rise and super high-rise buildings in the city, and the urban space has become more and more crowded, such as the basement of high-rise buildings, subways and rail transit, underground shopping malls and commercial streets, civil air defense A large number of underground buildings such as fortifications have been built, and they are developing in the direction of large depth and large area. The surrounding environment is more complex, the investment is large, the construction speed is slow, and the difficulty of foundation pit excavation and support is increasing. [0003] At present, the most widely used foundation pit support forms are: sloping excavation, steel sheet pile support, soil nail wall support, column type cast-in-situ pile row pile suppo...
