Embodiment 1

[0032] Such as figure 1 As shown, the mixing pile can be used with a five-axis mixing pile that can be converted up and down with a grouting device.

[0033] Install the device on the drill pipe as shown in the figure. The movable hoop blade 1 is inserted into the drill pipe 5 and the direction is checked. The fixed sleeve 2 is welded on the drill pipe. The oar mouth 6.7 is aligned, and the movable hoop blade is guaranteed to rotate freely from 1° to 90°. The blades are welded on the drill pipe according to the drawing size.

[0034] The following is the use of the device on the five-axis stirring pile machine.

[0035] Specifically include the following steps:

[0036] (1) Stake out, release the real sample according to the construction drawing;

[0037] (2) Groove, and groove according to the drawing requirements;

[0038] (3) The device is in place, and the five-axis cement-soil mixing pile device is moved to the position to be constructed;

[0039] (4) Start the back...

Abstract

The invention relates to a cement soil mixing pile device capable of switching up and down to spray slurry and a construction method. The device is improved and optimized on the basis of an original cement soil mixing pile machine. The device comprises movable hoop vanes, fixing sleeves, mixing vanes, a drill rod and slurry spraying opening groups. Upper and lower slurry spraying openings are automatically closed or opened under the action of the mechanical force of the movable hoop vanes according to different mixing directions, the lower slurry spraying opening sprays slurry when the drill rod drills downwards, and the upper slurry spraying opening sprays slurry when the drill rod is lifted. Compared with cement soil mixing pile devices and construction methods in the prior art, the cement soil mixing pile device capable of switching up and down to spray slurry and the construction method have the advantages that the mixing is uniform, the mixing efficiency is high, costs are low, the efficiency is high, the construction period is shortened, and the like.

Description

technical field [0001] The invention relates to a cement-soil mixing pile device and a construction method that can be converted up and down for grouting, and is mainly used in foundation pit enclosure and water stop and foundation reinforcement in civil and industrial infrastructure construction. Background technique [0002] At present, two-axis mixing piles, three-axis mixing piles, SMW construction method, FCW five-axis mixing piles, and six-axis mixing piles are mostly used for foundation pit enclosure waterstop and foundation reinforcement. [0003] Cement-soil mixing pile is a method used to reinforce saturated and soft clay foundations. It uses cement as a curing agent, and through a special mixing machine, the soft soil and curing agent are forced to mix deep in the foundation. Using the curing agent and soft soil A series of physical and chemical reactions between them make the soft soil harden into a high-quality foundation with integrity, water stability and cert...
