Problems solved by technology

[0002] The bearing capacity of foundation piles in foundation engineering is the friction between the pile body and the surrounding rock and soil layer and the end resistance of the pile end soil layer. The pile body will penetrate through multiple layers of rock and soil layers, and there are several side resistance values ​​and end resistance values Larger, that is, rock and soil layers with better engineering performance; conventional bored square piles, with the same shape of pile body section, cannot fully exert the side resistance and end resistance of rock and soil layers with better engineering performance

Embodiment

[0015] The embodiment of the present invention provides a multi-branch drilled grouting square pile, see figure 1 , figure 2 , the multi-support disc bored square pile includes a pile body 1 , a steel cage 2 arranged in the pile body 1 , and a concrete support disc 3 arranged on the pile body 1 .

[0016] Specifically, see image 3 , The reinforcement cage 2 includes stirrups 21 , main bars 22 arranged inside the stirrups 21 , reinforcing bars 23 arranged on one side of the stirrups 21 , and densified areas 24 arranged between the stirrups 21 . The exposed end of the reinforced cage 2 after being arranged in the pile body 1 is an anchor bar 25 .

[0017] The beneficial effects brought by the technical solution provided by the embodiments of the present invention are:

[0018] In the case of the same single pile bearing capacity, reducing the cross-sectional area of ​​the pile body or reducing the length of the pile reduces the volume of the pile body and saves materials. ...

Abstract

The invention discloses a multi-branch disk square bored pile and belongs to the field of buildings. The multi-branch disk square bored pile comprises a pile body, a steel reinforcement cage and concrete branch disks, wherein the steel reinforcement cage is arranged in the pile body; the concrete branch disks are arranged on the pile body. Compared with a square bored pile with equal length and equal sectional area, the multi-branch disk square bored pile has the advantages that under the condition that only a small number of concrete materials are added, the bearing capacity of a single pile is improved to a larger extent, the number of piles is decreased, and the cost of pile foundation engineering is reduced.

Description

technical field [0001] The invention relates to the field of construction, in particular to a multi-branch drilled grouting square pile. Background technique [0002] The bearing capacity of foundation piles in foundation engineering is the friction between the pile body and the surrounding rock and soil layer and the end resistance of the pile end soil layer. The pile body will penetrate through multiple layers of rock and soil layers, and there are several side resistance values ​​and end resistance values Larger, that is, rock and soil layers with better engineering performance; conventional bored square piles, with the same shape of pile body section, cannot fully exert the side resistance and end resistance of rock and soil layers with better engineering performance. Contents of the invention [0003] In order to solve the problems in the prior art, an embodiment of the present invention provides a multi-branched bored cast-in-place pile. Described technical scheme i...
