Abstract

The invention relates to the technical field of pouring guide pipe blocking, and discloses a construction method for relieving pouring guide pipe blocking. The construction method for relieving pouring guide pipe blocking is characterized by comprising the following construction steps that (1), when a pouring guide pipe is blocked, a pouring hopper is detached from the pouring guide pipe; (2), a crane is adopted to hoist a vibratory hammer to the position above a top opening of the pouring guide pipe, and a pipe joint is connected with the top of the pouring guide pipe; (3), the lifting state of the crane to the vibratory hammer is kept, and in-situ vibration of the vibratory hammer is started; and (4), the crane applies upward set lifting force to the vibratory hammer, when the pouring guide pipe is loosened, it is judged that the pipe blocking phenomenon is relieved, and when the pouring guide pipe is kept in a fixed state, the step (3) is repeatedly operated and carried out. The instant high-frequency exciting force of the vibratory hammer can directly act on the pouring guide pipe through the pipe joint, so that the pouring guide pipe and concrete are transited from a compressed state to an instant separation state, and pipe blockage is quickly relieved.

Description

technical field

[0001] The patent of the present invention relates to the technical field of perfusion catheter blockage, in particular, to a construction method for removing perfusion catheter blockage. Background technique

[0002] When pouring concrete into the bored pile to form the pile body, due to the small slump of the concrete, the blockage of the water stopper in the pouring conduit, the long waiting time for the concrete, and the deep buried pipe of the pouring conduit, etc., often occur If the perfusion catheter is blocked, if it is not dealt with in time, it will cause a perfusion accident.

[0003] When the perfusion conduit is blocked, there are generally two situations as follows: 1) The perfusion conduit can still be lifted, and the concrete in the perfusion conduit cannot be poured in normally. The method of lifting the perfusion catheter up and down by the winch is trying to use the shock force to release the blockage of the perfusion catheter; when there...
