Abstract

The invention relates to a vibrating immersed tube dry slurry perfusion special-shaped woven bag pile and a construction method. The vibrating immersed tube dry slurry perfusion special-shaped woven bag pile is provided with a dry slurry fixing pile body with an inverted camber curved surface, and the dry slurry fixing pile body is X-shaped, Y-shaped or cross-shaped; the top of the pile is provided with a X-shaped, Y-shaped, cross-shaped or round cover plate; the outer side of the dry slurry fixing pile is provided with a geotextile bag; the bottom of the geotextile bag is connected with a precast pile tip which has a same shape with the pile body; the geotextile bag is uniformly provided with a plurality of steel bar frameworks which have same shape with the pile body at intervals; the steel bar frameworks are connected in series by use of multiple steel wire ropes; the outer side of the pile body is provided with a sand layer which has same shape with the pile body and is used for discharging water; the outer side of the sand layer is uniformly provided with a plurality of sand wall wing plates in the radial direction. A special-shaped section is adopted, so that the side friction resistance is large, the water absorption and consolidation of a dry slurry can be accelerated, and insufficient dry slurry pile core consolidation is effectively avoided; meanwhile, the sand layer arranged at the outer side can be used for preventing soil particles into the dry slurry and further influencing dry slurry consolidation strength, the sand layer is capable of achieving a water discharging effect all the time, the effect of soil consolidation between the piles can be accelerated, and the vibrating immersed tube dry slurry perfusion special-shaped woven bag pile has favorable technical and economical benefits.

Description

technical field [0001] The invention relates to a vibrating immersed tube dry material perfusion special-shaped bag pile and a construction method thereof, which belong to the field of foundation engineering and are suitable for foundation treatment projects in soft soil areas and under-consolidated soil areas with insufficient foundation bearing capacity, especially in soft soil layers It has great advantages in the foundation treatment of road engineering with high settlement requirements such as thick bridge heads, culverts, and passages. Background technique [0002] There are many types of soft soil foundations in my country, which are widely distributed, and generally have the characteristics of high water content, high compressibility, low strength, and poor water permeability. Buildings built on soft soil foundations often have engineering problems such as excessive total settlement, obvious differential settlement, excessive later settlement, and insufficient bearin...
