Problems solved by technology

[0002] At present, in the process of forming holes in cast-in-situ piles, taking and unloading soil is the key in the construction process. Commonly used methods of taking and unloading soil are: 1. The mud retaining wall is punched (drilled) and the mud circulation is used to realize the discharge of soil slag from the hole. A large amount of mud needs to be prepared, and there is mud pollution; 2. Long helical drilling, although the mud wall is not used to form the hole, but when the soil rises in the helical blades and is discharged to the ground, part of the soil sticks between the helical blades, and the blades must be lifted out of the hole for special purpose. Cleaning has low work efficiency, and the diameter of conventional piles is small, so it is impossible to realize large-diamete

Embodiment Construction

[0023] A construction method of loose-leaf soil picking and unloading by improving the high-frequency vibratory hammer of the present invention will be further described below in conjunction with the accompanying drawings and specific examples.

[0024] First, by improving the structure of the high-frequency vibratory hammer, the soil-absorbing pipe and the soil-absorbing bin are designed as an integral structure;

[0025] Then, use the high-frequency vibrating hammer (1) to first sink the outer steel casing into the ground, and the working range of the integral structure of the soil-taking pipe and the soil-borrowing bin is set inside the outer steel casing, and the high-frequency vibrating hammer (1) passes through the The holder (2) clamps the soil-absorbing pipe (5), and tightens the wire rope (4) of the soil-absorbing pipe (5) through the hoist (3), so that the loose-leaf piece of the soil-absorbing pipe (5) is tightened upwards and close to the soil-absorbing pipe (5) ) inn

Abstract

The invention relates to a construction method adopting loose-leaf type soil taking and unloading by improving a high-frequency vibrating hammer. The technical core lies in that through improving the structure of the high-frequency vibration hammer, a soil taking pipe and a soil taking bin are designed into an integral structure; the soil taking bin is provided with a plurality of movable bin doors and the doors can move; and the opening and closing of the bin doors is controlled through steel wire ropes. On one hand, the situation that a bolt is adopted to limit the bin doors is avoided; and on the other hand, the soil is unloaded from the bin doors of the soil taking bin, the situation that the soil is left on the soil taking bin is avoided, and the soil unloading is thorough. The operation is semi-automatic and the efficiency is extremely high.
