Embodiment

[0050] Embodiment: the preformed hole lateral restraint pile in the present embodiment comprises reinforced filter screen 5 and coarse particle filler 6, and coarse particle filler 6 is wrapped in the inside of reinforced filter screen 5, makes reinforced filter screen 5 to coarse particle Filler 6 produces lateral restraint and has good integrity.

[0051] The prefabricated hole lateral restraint pile in the present embodiment has the following steps during concrete construction:

[0052] 1. Design:

[0053](1) The design parameters of the preformed hole deep layer dense large-diameter laterally restrained coarse particle filling pile method include: pile hole diameter, pile diameter, pile distance, pile length, vibration frequency of vibrating rod and vibration density time (or compaction energy level and Rammer diameter), outer pipe pull-up speed, diameter and strength of reinforced filter, foundation treatment requirements (foundation bearing capacity, deformation modulus...

Abstract

The invention relates to the field of foundation treatment and deep foundation construction, in particular to a pre-perforated lateral restraint pile and a construction method thereof. The pre-perforated lateral restraint pile and the construction method thereof are characterized in that a coarse particle fill stratum and a deep soft soil layer can be penetrated in one time to realize bottoming of a pile body; under a load action, coarse particle materials are restrained laterally by a high-strength high-toughness reinforced filter screen, and bearing capacity and deformation resistance of the pile body can be given full play to; the pile body with coarse particle fillers and the reinforced filter screen is enhanced integrally, shear capacity is improved, and the problem of breakage of gravel piles is solved. The pre-perforated lateral restraint pile and the construction method thereof have the advantages that realization of one-time penetration of the coarse particle fill stratum and the deep soft soil layer, realization of underwater construction, realization of lateral restraint with the high-strength high-toughness reinforced filter screen, deformation control, controllability and adjustability of density and rigidity of the ultralarge-diameter coarse particle filled lateral restraint pile, formation of quick drainage passage, acceleration of soft soil solidification, low manufacturing cost, high efficiency, energy saving, environment friendliness and the like.

Description

technical field [0001] The present invention relates to the fields of foundation treatment and deep foundation construction, in particular to a preformed hole lateral restraint pile and its construction method, and specifically refers to a preformed hole dense super large diameter integrated lateral restraint pullout-resistant drainage energy-saving environmental protection coarse particle filling pile method, It is a foundation treatment and deep foundation construction technology that consolidates and strengthens soft soil foundations such as backfilling rocks, construction waste, and industrial waste residues on the surface, and soft soil foundations such as silt and silt on the deep layer. Background technique [0002] Conventional compacted crushed stone piles are formed into holes by machines, and then crushed stones with strict particle size requirements are filled into the holes to compact into piles, and then interact with the soil between the piles to form a composi...
