Abstract

The invention discloses a lock device for a pressure dispersive type detachable anchor cable. The lock device is characterized by comprising a lock body, wherein a conical hole through which an anchor cable penetrates is formed in the lock body; a locking block is embedded in the conical hole; and an unlocking cross beam connected with a driving device is arranged at the lower end of the lock body, and is clamped with a tail fin extended on the locking block. The lock device for the pressure dispersive type detachable anchor cable has a reasonable structural design, can achieve a good fixing effect, can ensure design pull force required by construction and can take a non-bonded anchor cable left in a soil body out smoothly after an anchor rod fails. The locking block can be unlocked from the unlocking cross beam conveniently and quickly, and the lock device has low using cost.

Description

technical field [0001] The invention belongs to the construction technique and equipment device of the anchor rod engineering in building foundation construction, and in particular relates to a detachable pressure dispersion type detachable anchor cable lock device. Background technique [0002] In the prior art, in the deep foundation pit support engineering of buildings, bolt construction is an indispensable engineering construction part. The method used in the traditional anchor rod or anchor cable construction technology is: the engineering drilling rig drills a hole with a depth of about 20 meters to 50 meters at a horizontal inclination angle of 5° to 30° between the foundation pit surrounding protection piles, and then puts the bare steel hinge harness , and then inject cement slurry. After the cement slurry solidifies and reaches a certain age to produce strength, the steel strand and cement condense into a structural column. The structural column tensions and locks ...
