Abstract

The invention discloses a grave pile construction method applicable to saturated soft soil, wherein the grave pile construction method comprises the following steps: sinking a first seamless steel sleeve into hard soil by a certain depth, and finishing pore-forming construction in the first seamless steel sleeve, sinking a second seamless steel sleeve in the hard soil; finishing the pore-forming construction in the second seamless steel sleeve, adopting a grading gravel filler to fill pile holes in the second seamless steel sleeve; adopting the grading gravel filler to fill pile holes between the first seamless steel sleeve and the second seamless steel sleeve until the pile holes being flush with a first scale plate form the bottom; sinking and placing a reinforcement cage between the first seamless steel sleeve and the second seamless steel sleeve, wherein the internal side surface of the reinforcement cage is laid with geotechnical cloth; adopting the grading filler to fill the pile holes between the first seamless steel sleeve and the second seamless steel sleeve until the pile holes being flush with a second scale plate from the bottom, repeating the steps until reaching a top layer of the saturated soft soil. By adopting the grave pile construction method provided by the invention, a pile body with small pile diameter is prevented from being slant and deforming when adopting construction of quincuncial piles distribution.

Description

technical field [0001] The invention belongs to the field of saturated soft soil foundation treatment. More specifically, the present invention relates to a construction method of gravel piles suitable for saturated soft soil. Background technique [0002] As we all know, with the rapid development of the national economy, the rapid progress of science and technology, and the acceleration of domestic urbanization, the land for construction has become increasingly scarce, and many buildings have to be built on foundations that are not suitable for building foundations. However, in my country's widely distributed coastal areas, lakes, valleys, river beaches and other large areas of soft soil, more and more are used to build various large buildings. [0003] As a typical poor foundation, saturated soft soil has physical characteristics of high void ratio, high water content, low strength, and high compressibility, and has obvious rheological properties. In pile foundation con...
