Embodiment Construction

[0043] The following is attached Figure 1-6 The application is described in further detail.

[0044] The embodiment of the present application discloses a foundation structure in which surface soil is solidified in situ and combined with piles. refer to figure 1 , the foundation structure includes several piles 2 inserted in the in-situ soil layer 1 and uprights 7 for fixing the piles 2, the top of the uprights 7 is fixedly provided with a clamping mechanism for clamping uprights 7 and for connecting uprights 7 brackets 13 .

[0045] refer to figure 1 and figure 2 , in this embodiment, the number of piles 2 is three, and the three piles 2 are arranged vertically, and the three piles 2 are distributed in an equilateral triangle. The bottom end of the pile body 2 is fixedly provided with an installation block 4, and the lower surface of the installation block 4 is welded with several insertion rods 18. The lower surface of the in-situ soil layer 1 is the bearing layer 3, ...

Abstract

The invention relates to a foundation treatment method, in particular to a foundation construction method capable of achieving surface soil on-site solidification and pile combined bearing. The foundation construction method comprises the following steps that 1, a solidification material and in-situ soil are subjected to on-site stirring solidification in an in-situ soil layer to form a solidification layer; 2, three or more than three pile bodies are sequentially driven into the in-situ soil layer to enable the three or more than three pile bodies to be distributed in a polygonal shape; 3, astand column used for fixing the pile body is installed on each pile body; 4, each stand column is sleeved with a fixing ring, and the multiple fixing rings are connected together through a support; 5, a clamping mechanism used for clamping the stand column is installed at the top end of each stand column; and 6, the pile bodies and the stand columns are connected together through the clamping mechanisms. By means of the foundation treatment method, the pile bodies can be prevented from inclining under the pressure effect of a foundation.

Description

technical field [0001] The present application relates to a foundation treatment method, in particular to a foundation construction method in which surface soil is solidified in situ and combined with piles. Background technique [0002] With the rapid development of engineering construction such as coastal ports, industrial buildings, and highway transportation, especially some projects need to be built in areas with soft soil, the high porosity of soft soil in microstructure is an important factor affecting its compression deformation, resulting in Soft soil has high compressibility, low shear strength and poor permeability, so deep soft soil needs to be reinforced. [0003] The commonly used reinforcement method for soft soil foundation is composite foundation method. The composite foundation method is to drive the pile body into the in-situ soil layer to achieve a compact effect on the in-situ soil layer. During the pile driving process, the bottom end of the pile body ...
