Construction method of solidified soil pile

Abstract

The invention provides a construction method of a solidified soil pile. The construction method comprises the following steps (1) pre-mixing solidified soil; adding water into an air hardening inorganic cementing material for dilution and blending to form initial material slurry, blending the initial material slurry with a powdery curing agent to form curing agent slurry, and mixing the curing agent slurry with soil to form on-site blended solidified soil; (2) downward drilling to form a hole; firstly drilling downwards to a designed depth, and arranging a soil sampling device on a drill rod; (3) lifting a bit, pressing and filling solidified soil; and pressing and pouring the solidified soil in the step (1) into a pile hole to form the solidified soil pile. According to the solidified soil pile constructed through the method, the air hardening inorganic cementing material is added, the solidification time of solidified soil is adjusted, and the acid-base property of the solidified soil is adjusted; and the slag is doped to reduce the cement consumption, the cost is greatly saved, the pile body strength is high, the bearing capacity is high, the construction process is simple, and the construction efficiency is high.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a pile construction method with solidified soil. Background technique [0002] In the field of civil engineering, the traditional rigid pile construction mainly includes the hammering method and the static pressure method. Both of these two methods have problems such as large pile sinking resistance, slow speed, and serious soil extrusion. During the construction of rigid piles, the surrounding Hazards to buildings, pipelines and structures. Although taking some stress relief measures can alleviate the harm of soil compaction, practice has proved that the harm of soil compaction is difficult to eliminate. In addition, the greater the formation resistance, the greater the pressure to sink the pile, resulting in greater damage to the pile during the pile sinking process. In order to protect the pile body from damage during the construction process, it is necessary to us...

Problems solved by technology

Another method is to reduce the resistance of the pilot hole, which not only increases the construction cost, but also reduces the lateral friction of the foundation soil, resulting in a reduction in the bearing capacity of the pile foundation, thereby increasing the construction cost.

[0003] In the weak soil layer of silt, due to the low frictional resistance of the soil, the lateral bearing capacity of the pile body is small, so that the strength of the pile body material cannot play a role and cannot be fully used, resulting in a large waste

[0004] Most of the existing composite piles are cement-soil mixing piles with a core pile structure, but cement-soil mixing piles will produce a large amount of mud, causing environmental pollution and waste of materials
