Embodiment

[0022] Such as figure 1 As shown, a casing capable of jetting, spraying (liquid), and stirring and its use method, the casing mainly includes stirring teeth 1 on the inner wall, air injection holes 2, spraying (liquid) holes 3, cutting and stirring at the end Teeth 4, end spray port 5, the air spray hole 2 is set above the stirring tooth 1 on the inner wall, the spray (liquid) hole 3 is set below the stirring tooth 1 on the inner wall, and the end spray port 5 is set on The outer wall of the casing end.

[0023] The present invention designs a casing pipe capable of spraying air, spraying grout (liquid), and stirring and using method thereof, and its construction steps are as follows:

[0024] A. When the casing sinks, the end cutting and stirring teeth 4 assist in cutting the soil, and the air injection hole 2 can spray air to assist soil fetching or the spray (liquid) hole 3 can spray water to assist cutting;

[0025] B. The casing sinks to the design depth;

[0026] C. A...

Abstract

The invention relates to a casing pipe capable of spraying air, spraying slurry (liquid) and stirring. The casing pipe mainly comprises inner wall stirring teeth, air spraying holes, slurry (liquid) spraying holes, end cutting stirring teeth and end slurry spraying openings, wherein the air spraying holes are formed above the inner wall stirring teeth, the slurry (liquid) spraying holes are formedbelow the inner wall stirring teeth, and the end slurry spraying openings are formed in the outer wall of the end of the casing pipe. According to the casing pipe capable of spraying the air, spraying the slurry (liquid) and stirring, the problems that poured slurry, concrete and other materials cannot be vibrated and stirred during mechanical construction of the casing pipe are solved, soil taking or cutting and the like can be assisted, deep slurry spraying and stirring are conducted to improve the bearing capacity, and therefore the casing pipe is a multifunctional and efficient casing pipe.

Description

technical field [0001] The invention relates to underground construction machinery, in particular to a multifunctional high-efficiency casing. Background technique [0002] The casing is used in the hole-forming process in underground engineering construction, which can effectively prevent the hole from collapsing. For cast-in-situ piles, casing mechanical construction can reduce the number of cleaning holes and ensure the quality of piles; for occlusal piles, casing mechanical construction can ensure the verticality and construction quality of occlusal piles, and achieve effective occlusion. But at the same time, casing construction also has disadvantages. Some materials with poor fluidity cannot be stirred, so that dense piles cannot be formed, and the bearing capacity cannot be guaranteed. Contents of the invention [0003] The purpose of the present invention is to provide a bushing capable of spraying air, spraying grout (liquid), and stirring, aiming at solving the ...
