Technical Field

The invention relates to the technical field of foundation treatment devices, in particular to a cement soil stirring drill rod and a pile machine thereof.

Background

Soft clay, also called soft soil, is mostly distributed in coastal areas, downstream in rivers or areas near lakes, and common soft and weakly sticky soils are silt and mucky soil.

The soft clay is mostly dark grey, dark green, odorous, contains organic matters, has high water content, generally more than 40 percent, and the sludge is also more than 80 percent. The porosity ratio is generally 1.0-2.0, wherein a porosity ratio of 1.0-1.5 is called silty clay, and a porosity ratio greater than 1.5 is called silt. Because of high viscosity grain content, high water content and large porosity ratio, the mechanical property of the material also presents the corresponding characteristics: low strength, high compressibility, low permeability, high sensitivity.

The soft clay foundation has low bearing capacity and slow strength increase; the product is easy to deform and uneven after being loaded; the deformation rate is high and the stabilization time is long; has the characteristics of small permeability, thixotropy and rheological property. The common foundation treatment methods include a prepressing method, a replacement method, a stirring method and the like. The stirring method uses cement as a curing agent, forcibly stirs the soft soil and the curing agent in the deep part of the foundation through a special stirring machine, and hardens the soft soil into a high-quality foundation with integrity, water stability and certain strength by using a series of physical and chemical reactions generated between the curing agent and the soft soil. And by adopting a direct pouring method, the formed cement-soil mixing pile has poor quality and low strength and cannot meet the design requirement.

Disclosure of Invention

The invention provides a cement soil mixing drill rod and a pile machine thereof to overcome the defects of the prior art.

The technical scheme of the invention is as follows:

the utility model provides a soil cement stirring drilling rod, includes the hollow pile pipe, the hollow pile intraduct articulates through the bolt has the drill bit, the drill bit with hollow pile intraductal chamber is sealed, the drill bit becomes conical step, the drill bit bottom is formed with cross recess or cross rib, the welding of hollow pile pipe side has the blast pipe that feeds through to hollow pile intraduct chamber, and the intercommunication position of blast pipe and hollow pile pipe is located the bottom of hollow pile pipe, hollow pile pipe side is equipped with the hopper that feeds through to hollow pile intraduct chamber.

The invention is preferably as follows: the exhaust pipe is a steel pipe.

A cement mixing pile machine comprises the cement mixing drill rod.

In the invention: the cement mixing pile machine also comprises a pile hammer, wherein the pile hammer is a drop hammer, a steam hammer, a diesel hammer or a hydraulic hammer.

The cement mixing pile machine also comprises a winch, a pile frame, accessory equipment, a guide frame and a guide rod.

Compared with the prior art, the invention has the beneficial effects that: when the cement soil mixing pile machine with the cement soil mixing drill rod is used for piling, the cement soil mixing pile with good quality and high strength and capable of meeting the design requirement can be obtained, the strength of the cement soil mixing pile after 28 days is improved by more than 1 time compared with that of the cement soil mixing pile in the prior art, cement can be saved, the transportation cost can be saved due to the fact that the soil adopted by the cement soil mixing pile machine is convenient to obtain, and the problems of low pile body strength and poor quality caused by direct mixing of the cement and silt or organic soil in the cement soil mixing pile in the prior art are solved.
