Abstract

The invention relates to a reamable rotatable grabbing bucket device and a using method thereof. The device mainly comprises a grabbing bucket bracket, a correcting device, a hydraulic rotary motor, ajacking oil cylinder, a connecting rod, square buckets, square bucket pins, plate tooth pin shafts, plate teeth and plate tooth sleeves. The correcting device is arranged on the grabbing bucket bracket; the hydraulic rotary motor is mounted in the central position of the grabbing bucket bracket; the jacking oil cylinder is connected with the hydraulic rotary motor; one end of the connecting rod is connected with the jacking oil cylinder; the other end of the connecting rod is connected with each of the square buckets and the plate tooth sleeves; and the plate teeth are embedded into the platetooth sleeves. The reamable rotatable grabbing bucket device can realize integrated soil grabbing and reaming; a continuous wall forms bosses to increase the bearing capacity; the depth of a wall body is reduced effectively; and the cost is reduced.

Description

technical field [0001] The invention relates to underground construction machinery, in particular to a reamable and rotatable grab device of an underground continuous wall groove forming machine. Background technique [0002] Diaphragm wall is a commonly used construction technology in the field of underground engineering. It is often used for ultra-deep underground space enclosure construction, and also for underground space construction in complex environments or key protection areas. It mainly has the functions of water interception, seepage prevention, and soil retaining. . The underground diaphragm wall uses ultra-deep wall widths to fall to the bottom of the hard bearing layer to solve the problem of load-bearing and settlement, which increases the cost of the project. During ultra-deep construction, the traditional grab is prone to burial, jamming, and the verticality of the wall cannot be controlled. Shortcomings. Contents of the invention [0003] The purpose of...
