Embodiment Construction
[0059] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0060] A SMW construction method based on two-way mixing. The process principle is to change the one-way mixing construction method in the traditional three-axis mixing construction into a two-way mixing construction method to form a new construction method. Specifically in this example, by using the concentric biaxial drill pipe, it plays the role of grouting and mixing cement and soil in the process of forward and reverse rotation, blocking the upward flow of cement slurry and ensuring the cement slurry in the pile. Evenly distributed in the body; at the same time, due to the addition of counter-rotating blades, the mixing of cement and soil is more complete, ensuring the construction quality. Such as Pic 4-1 and 4-2 As shown, the construction machine of this construction method includes a chassis 4.1, a frame 4.2, a power box 4.3, a drill...
