Abstract

The invention relates to an arch combination foundation pit retaining and protection system and a construction method of the arch combination foundation pit and protection system, and provides a combination foundation pit retaining and protection system which is simple in structural style, fast in construction method, capable of sufficiently utilizing property advantages of materials and combining the soil blocking function and waterproof function, and suitable for an arch-shaped cement soil mixing pile large in excavating depth and prefabrication of a high-strength concrete thin-wall steel tube pile, and the construction method of the combination foundation pit retaining and protection system. The arch combination foundation pit retaining and protection system comprises arch-shaped cement soil mixing pile walls (1), high-strength concrete thin-wall steel pipe piles (2), pile top beams (3) and inner supports (4), wherein the high-strength concrete thin-wall steel pipe piles (2) are arranged inside the foundation pit in a scattered mode, the pile top beams (3) connect the high-strength concrete thin-wall steel pipe piles into a whole, each inner support (4) is arranged on the outer side of each high-strength concrete thin-wall steel pipe pile (2), each arch-shaped cement soil mixing pile wall (1) is arranged between two high-strength concrete thin-wall steel pipe pile (2) and the arch-shaped cement soil mixing pile walls (1) to be connected into a whole, and the arch-shaped foundation pit retaining and protection system is formed.

Description

technical field [0001] The invention relates to a combined foundation pit support system and a construction method thereof, and belongs to the technical field of foundation pit support of geotechnical engineering. It is suitable for the enclosure construction of foundation pit engineering with large excavation depth and shallow buried water table, especially in soft soil and silt silt geological conditions. Background technique [0002] The main function of foundation pit support system is to retain soil and stop water. As the rigid support system of the foundation pit, the cement-soil mixing pile retaining wall can play the role of soil retaining and water stop at the same time, but the excavation depth of the foundation pit is limited due to the low tensile properties of the material. The improved section steel cement-soil mixing pile retaining wall is to insert section steel into the continuously socketed cement-soil mixing pile to form a composite soil-retaining and wat...
