Problems solved by technology

[0003] However, the bearing capacity of ordinary aggregate piles mainly depends on the lateral restraint provided by the surrounding soil, but in very soft soils, where the soil is undrained and the shear strength is weak, the surrounding soil cannot give the pile body provide sufficient lateral restraint to cause excessive expansion of the upper portion of the pile to failure

Abstract

The invention discloses a multi-reinforced granular material pile, which is arranged inside soft soil, and comprises hollow cylindrical vertical reinforcement and filler filled in the vertical reinforcement, and the vertical reinforcement circumferential surface in the filler is evenly arranged along the axial direction There are horizontal reinforcements, the horizontal reinforcements are placed between the fillers, and the axial reinforcements are evenly arranged along the radial direction of the vertical reinforcements. The multi-reinforced granular material pile of the present invention is more suitable for soft soil. The present invention also provides a construction method of the above-mentioned multi-reinforced granular pile.

Description

technical field [0001] The invention belongs to the field of improvement and reinforcement of bad foundations, and relates to a novel multi-reinforced granular material pile and a construction method thereof. Background technique [0002] With the acceleration of urbanization and the growth of infrastructure, the demand for land space has risen sharply. There are many soft soil surfaces in natural land resources that are not suitable for construction, which forces the construction industry to find a suitable improvement method to improve these soft soil surfaces so that they can meet the requirements of engineering construction. The reinforcement method of granular piles is considered to be an economical, simple and effective method, and it has been widely used in engineering practice. [0003] However, the bearing capacity of ordinary aggregate piles mainly depends on the lateral restraint provided by the surrounding soil, but in very soft soils, where the soil is undraine...
