Description

Technical Field

[0001] The present application relates to the technical field of building structures, and specifically discloses a pile foundation detection acoustic detection tube expansion and contraction compensation device. Background Art

[0002] The pile foundation acoustic detection tube is a pile foundation acoustic detection tube bound to the pile foundation steel cage of the cast-in-place pile. It is also called the pile foundation acoustic detection tube for pile foundation detection. The function of the pile foundation acoustic detection tube is to detect the position of the pile in the foundation. When the pile foundation is driven into the foundation, the pile foundation acoustic detection tube will make a sound. By analyzing the sound, the position of the pile can be determined.

[0003] The method of using the pile foundation acoustic detection tube is to install it on the ground and then guide it to the pile to be driven into the foundation. When the pile is driven into the foundation, the sound will be transmitted through the pile foundation acoustic detection tube.

[0004] In the prior art, pile foundation acoustic detection pipes are divided into connection forms such as clamping type, spiral type and sleeve type. For the clamping type acoustic detection pipe, including the bottom pipe, middle pipe, top pipe and double joint, the bottom of the bottom pipe is closed with a cover, the pipes are connected through the double joint, and the pipes and the double joints are pressed together by external pressure. A rubber cap is also installed on the top of the top pipe for sealing.

[0005] During the on-site construction process, the actual construction pile length is generally greater than the designed pile length, and the pile foundation acoustic detection tubes are pre-clamped and then installed, and their lengths are fixed. Therefore, during the actual construction process, the pile foundation acoustic detection tubes may not be buried to the bottom of the pile.

[0006] Therefore, in view of this, the inventor provides a pile foundation detection acoustic detection tube expansion and contraction compensation device to solve the above-mentioned problem. Utility Model Content

[0007] The utility model aims to solve the problem that the traditional pile foundation acoustic detection pipe may not be able to be buried to the bottom of the pile due to the non-adjustable length during the actual construction process.

[0008] In order to achieve the above purpose, the basic scheme of the utility model provides a pile foundation detection acoustic detection pipe expansion and contraction compensation device, including a connecting pipe with one end fixedly connected to an adjacent pipeline and a compensation pipe threadedly connected to the other end of the connecting pipe and fixedly connected to the adjacent pipeline.

[0009] Furthermore, an inner wall of one end of the connecting pipe connected to the compensating pipe is provided with an internal thread, and an outer wall of one end of the compensating pipe connected to the connecting pipe is provided with an external thread meshing with the internal thread.

[0010] Furthermore, an end portion of the connecting pipe connected to the compensating pipe also extends outward to form an extension portion that wraps around the compensating pipe.

[0011] Furthermore, the inner wall of the extension portion is also provided with an internal thread engaged with the external thread.

[0012] Furthermore, a sealing ring is provided at the bottom end of the extension portion and fits the outer wall of the compensation tube.

[0013] Furthermore, a compression groove which does not penetrate the outer wall of the connecting pipe is formed on the connecting pipe.

[0014] The principle and effect of this scheme are:

[0015] Compared with the prior art, the utility model extends the bottom end of the compensation pipe into the bottom pipe and clamps it after determining the length of the pile to be installed, and then connects the connecting pipe and the compensation pipe through the engagement of the external thread and the internal thread. The overall pipe length can be controlled by the depth of the thread engagement. After determining that the overall length of the subsequent installation will exceed the length of the pile, that is, a certain length is reserved for the acoustic detection pipe, the middle pipe and the top pipe are fixed in turn by clamping, which solves the problem that the traditional pile foundation acoustic detection pipe cannot be buried to the bottom of the pile due to the non-adjustable length during the actual construction process.
