Diving power head for producing pile with nonlinear section

Abstract

The invention relates to a diving power head for producing a pile with a nonlinear section. The diving power head comprises a driver system capable of providing circumferential rotating power, and is characterized in that the driver system is connected with a drill rod mechanism consisting of driving drill rods and driven drill rods; the center lines of the driving drill rods and the driven drill rods which form the drill rod mechanism are not in the same plane; the driving drill rods and the driven drill rods in the drill rod mechanism are mutually connected through a transmission system, so that a plurality of driving drill rods and a plurality of driven drill rods can rotate at the same time. In the working process of the diving power head, a nonlinear cement-soil mixing pile is directly formed; the production process is fast and high in efficiency; the nonlinear cement-soil mixing pile is high in strength.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, in particular to a submersible power head for making non-linear piles in section. Background technique [0002] Pile driver is a kind of pile machinery used for piling. There are many kinds of pile machinery. Manufacture of solid mixing piles, cement-soil mixing piles are a method for reinforcing saturated soft clay low foundations, which use cement as a curing agent, and use a special mixing machine to forcefully mix the soft soil and curing agent deep in the foundation. Using a series of physical and chemical reactions between the curing agent and the soft soil, the soft soil can be hardened into a high-quality foundation with integrity, water stability and certain strength. Common pile drivers for cement-soil mixing piles usually use multiple drill pipes to work at the same time to drill holes. Most of the existing drill pipes are driven by one or more drivers to rotate in the ...

Problems solved by technology

[0004] Although the above-mentioned scheme solves the problem that the drill pipes of the existing cement-soil mixing pile machine can only rotate in the same direction to a certain extent, because the cement-soil mixing pile produced by this scheme is in a straight line, the strength of the cement-soil mixing pile is not high. , in addition, the main drill pipe and the auxiliary drill pipe of this scheme need to be lengthened during the drilling operation, and the rotation of the main drill pipe and the auxiliary drill pipe needs to be stopped during the lengthening process, which affects the work efficiency, and the main drill pipe and the auxiliary drill pipe The longer the length, the greater the resistance of the soil and the less likely it is to rotate
