The absorbing connector of a ground settlement or heave for ground movement measuring pipe

摘要

The present invention relates to a joint of the ground displacement measurement pipe, the configuration is formed in the longitudinal direction on the inner circumferential surface, the fitting groove to be inserted and guided by the fitting jaw of the pipe; and located in the inner circumferential surface, the fitting groove An annular locking jaw limiting the insertion length of the pipe inserted into the pipe; and extending in a vertical direction by a predetermined length, and the pipe extends a predetermined length into upper and lower portions of a joint of the ground displacement measuring pipe. When inserted, the lower end of the pipe inserted into the upper portion and the upper end of the pipe inserted into the lower portion to be separated from each other by a predetermined distance with respect to the locking jaw; And, the pipe inserted into the upper and lower parts on the outer peripheral surface and the ground displacement Characterized in that a plurality of bolt guide holes are formed to facilitate the bolt coupling to securely connect the joint of the measuring pipe; As,;By extending the upper and lower portions of the joint of the ground displacement measuring pipe in the longitudinal direction, the pipes inserted into the upper and lower portions of the joint of the ground displacement measuring pipe by a predetermined length are separated by a predetermined distance from the locking jaw. In the event of a strong force caused by excessive ground settling or uplift, the pipe does not counteract the force exerted, but is conveyed upwards or downwards in a direction that conforms to the force, thereby exerting the force exerted by the ground settling or uplift. Easily eliminated there is an effect that can prevent damage or destruction of the joints of the pipe and the pipe for the ground displacement measurement.
