Cement mixing pile construction method

Abstract

The invention discloses a cement mixing pile construction method, belongs to the field of building construction, and aims to improve the uniformity of cement grout and improve the strength of a pile body. The cement mixing pile construction method comprises the following steps: S100, piling coordinates are marked on an actual terrain; S200, a drilling machine is installed, and a cement mixing pile drill bit is installed on the drilling machine; S300, the drilling machine is controlled, and the cement mixing pile drill bit is driven to drill downwards to the designed depth; S400, the drilling machine is controlled, the cement mixing pile drill bit is driven to rotate reversely and ascend, and guniting is conducted through a nozzle; and S500, the drilling machine is controlled, and the cement mixing pile drill bit is driven to rotate reversely and ascend to the ground surface. By applying the cement mixing pile construction method, the uniformity of the cement grout can be improved, and the strength of the pile body is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method of a cement mixing pile. Background technique [0002] Cement mixing pile refers to an effective form of soft foundation treatment. It is a main agent that uses cement as a curing agent. The cement is sprayed into the soil by a mixing pile machine and fully stirred to make a series of physical and chemical reactions between the cement and the soil. , an effective method to harden soft soil and improve foundation strength. [0003] For cement mixing pile soft soil foundation treatment, the pile diameter of the mixing pile is mainly 50-60cm; when the pile diameter of the cement-soil mixing pile is enlarged, it is more difficult to control the strength around the pile, and the uniformity of the cement slurry is not high, and there will be Reduced diameter, high strength in the center of the pile, low strength in the periphery and other quality defects.
