Problems solved by technology
The strength of the cement-soil pile decreases with the increase of the comprehensive water content in the cement slurry and foundation soil, and also decreases with the increase of the fine particle content in the foundation soil. Therefore, to obtain higher cement-soil strength, the cement-soil pile should be controlled The comprehensive water content in the ground and the increase of the coarse particle content in the foundation soil, while the pure spraying or powder spraying deep mixer cannot adjust the water spraying amount according to the water content of the formation, and at the same time cannot adjust the coarse particle content in the foundation soil

Embodiment Construction
[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0015] The working principle of the pile driver of the present invention is the same as that of the prior art, so it is no longer described. The difference between the present invention and the prior art is that a new three-channel water joint, three-channel drill pipe and three-channel drill bit have been recombined and designed, and Combining the powder spraying device on the powder spraying pile machine, the spraying device of the deep stirring pile machine realizes simultaneous water spraying, powder spraying and sandblasting.
[0016] Such as figure 1 , 2 As shown, the mortar pile mixer for weak foundation reinforcement of the present invention includes a deep pile mixer 16, a water joint 18, a sand conveying device 23, a slurry pump 22, a powder conveying device 21, a bottom drill bit 20 and a drill rod 19, The water joint 18 is a three-...

The invention discloses a mortar pile stirrer for stabilizing a soft ground. The mortar pile stirrer comprises a deep mixing pile driver, a water joint, an air pump, a mortar delivery pump, a powder delivery device, a bottom drill bit and a drill rod, wherein the water joint is a three-channel water joint; an upper connecting disk of the water joint is connected with a pile driver connecting disk, and a lower connecting disk of the water joint is connected with a drill rod connecting disk; a shaft is provided with three delivery channels which are communicated with a sand delivery pipe, a powder delivery pipe and a water delivery pipe respectively; the powder delivery pipe, the sand delivery pipe and the water delivery pipe are also connected with the powder delivery device, a sand delivery device and the mortar delivery pump respectively; the drill rod is a three-channel drill rod; the bottom drill bit is a three-channel drill bit; and the corresponding channels of the three-channel water joint, the three-channel drill rod and the three-channel drill bit are interconnected. The mortar pile stirrer realizes respective ejecting of water, powder and sand, pre-stirring of water and other two media or pre-stirring and ejecting of three media together so as to achieve the function of simultaneous spraying of water, powder and sand and improve the piling quality.
Description
technical field [0001] The invention relates to a mixer, in particular to a mortar pile mixer used for weak ground reinforcement. Background technique [0002] In the construction of mixing piles in railway, highway, construction, municipal, water conservancy and port projects, deep mixers with simple grouting (wet spraying) or powder spraying (dry spraying) are usually used. The water-cement ratio of cement slurry, the water content of the foundation soil and the content of coarse particles in the foundation soil have a great relationship. The strength of the cement-soil pile decreases with the increase of the comprehensive water content in the cement slurry and foundation soil, and also decreases with the increase of the fine particle content in the foundation soil. Therefore, to obtain a higher cement-soil strength, the cement-soil pile should be controlled The comprehensive water content in the soil and the increase of the coarse particle content in the foundation soil,...
