Method for processing soft soil foundation with environment-friendly light pile

Abstract

The invention provides a method for processing a soft soil foundation with an environment-friendly light pile. The method comprises the following steps: 1) preparing materials for the environment-friendly light pile; 2) preparing pile forming equipment for the environment-friendly light pile; 3) preparing a piling machine, and starting a vibration hammer for piling a guide hole pile pipe to a design depth; 4) upwardly pulling the guide hole pile pipe to guarantee that a movable bottom door pile tip is completely opened; 5) feeding a prepared environment-friendly light mixture to a feeding hole of the guide hole pile pipe for the first time; 6) starting an impact heavy hammer for continuously impacting the environment-friendly light mixture in the guide hole pile pipe for 2-6 times to form a dense expanded pile body; 7) feeding for the second time and tamping a pile top for 2-5 times by the impact heavy hammer; 8) continuously lifting the guide hole pile pipe until the distance from the bottom of the guide hole pile pipe to the ground is 30-50 cm, shifting the piling machine, filling up the pile top with soil and tamping or rolling the pile top; and 9) repeating the steps 3) to 8) until the reinforcement treatment of the soft soil foundation is finished. The method has the benefits as follows: the reinforcement effect is good, waste materials are turned into wealth, the cost is low, and the environment is protected.

Description

technical field [0001] The invention belongs to the field of reinforcement treatment of shallow layers of deep soft soil in civil engineering construction, and in particular relates to a method for treating soft soil foundations with environment-friendly lightweight material piles. Background technique [0002] my country has a vast territory and a wide range of soft soil distribution. No matter in the coastal areas, inland plains, or in the western mountainous areas, the problem of soft soil foundation treatment is often encountered in engineering construction. Although the causes, structures and forms of soft soil are different, there are It has the characteristics of high water content, high compressibility, low strength and poor water permeability. [0003] For the deep sedimentary soft soil and wetland soft soil along rivers, rivers, lakes and other areas, when using traditional technology for foundation treatment, the cost is often high, the construction technology is c...

Problems solved by technology

[0002] Our country has a vast territory and a wide range of soft soils. No matter in the coastal areas, inland plains, or in the western mountainous areas, we often encounter problems in the treatment of soft soil foundations in engineering construction. Although the causes, structures and forms of soft soils are different, they all have Features of high water content, high compressibility, low strength and poor water permeability

[0003] For the deep sedimentary soft soil and wetland soft soil along rivers, rivers, lakes and other areas, when using traditional technology for foundation treatment, the cost is often high, the construction technology is complicated, and it is easy to damage the original ecological environment outside the building
