Abstract

The invention relates to the technical field of building construction, in particular to a secant pile construction method and a reinforcing structure. The secant pile construction method comprises the following steps that S1, construction preparation is conducted; S2, a first plain concrete pile is constructed to form an A1 pile; S3, a second plain concrete pile is constructed to form an A2 pile; S4, a first reinforced concrete pile is constructed to form a B1 pile, and the B1 pile is arranged in a secant mode with the A1 pile and the A2 pile; S5, the step S3 is repeated to form a pile A3, the step S4 is repeated to form a pile B2, and the pile B2 is arranged in a secant mode with the pile A2 and the pile A3; S6, the step S5 is repeated, and the construction sequence of all the piles is A1-A2-B1-A3-B2-A4-B3-A5-B4-... An-Bn till secant pile construction is completed; and S7, guide wall construction is conducted. The secant pile construction method is suitable for geology such as moderately-weathered siltstone, strongly-weathered siltstone, cohesive soil, silty soil, sandy soil and artificial filling soil.

Description

technical field

[0001] The present disclosure relates to the technical field of building construction, in particular to a construction method and reinforcement structure of an occlusal pile. Background technique

[0002] With the continuous growth of the domestic economy, cities are developing towards high altitudes, urban transportation is developing into multi-level and three-dimensional development, and the subway rail transportation industry is deeply plowing the ground. Following the needs of the development of the times, the technical requirements are getting higher and higher, and the effective super large deep foundation pit support structure is particularly important for cities with many tall buildings, heavy traffic, and every inch of land.

[0003] The full-casing long helical drilling air pressure reverse circulation pressure grouting occlusal pile realizes the integration of hole forming, wall protection and pouring, and does not need to be connected to the wall...
