[0013] The present invention is further described below in conjunction with specific implementation methods. The specific implementation methods are further descriptions of the principles of the present invention and do not limit the present invention in any way. Technologies that are the same or similar to the present invention do not exceed the scope of protection of the present invention.
[0014] See attached Figure 1-3 , a detachable pre-buried pipe sealing device includes a pipe cap 1 and an annular groove 5; the annular groove 5 is arranged on the pipe cap 1; the geometric shape of the annular groove 5 matches the geometric shape of the pre-buried pipe 4 to be blocked; the pre-buried pipe 4 to be blocked includes an internal cavity; the end of the pre-buried pipe 4 can be embedded in the annular groove 5; the annular groove 5 includes a groove inner wall 502 and a groove outer wall 501; the radial distance between the groove inner wall 502 and the groove outer wall 501 is greater than the thickness of the pipe wall 401 of the pre-buried pipe 4 to be blocked; when the end of the pre-buried pipe 4 is embedded in the annular groove 5, the groove inner wall 502 can extend into the internal cavity of the pre-buried pipe 4, and the groove outer wall 501 can be sleeved on the outer wall of the pre-buried pipe 4.
[0015] Before concrete pouring, the end of the pre-buried pipe 4 is embedded in the annular groove 5 of the pipe cap 1, wherein the inner wall 502 of the groove extends into the internal cavity of the pre-buried pipe 4, and the outer wall 501 of the groove is sleeved on the outside of the pipe wall 401 of the pre-buried pipe 4, thereby achieving the sealing of the end of the pre-buried pipe 4 by the pipe cap 1. For pre-buried pipes 4 of different shapes, the geometric shape and size of the annular groove 5 are adapted to the geometric shape and size of the pre-buried pipe 4. The inner diameter of the inner wall 502 of the groove and the outer dimensions of the outer wall 501 of the groove meet the geometric size requirements of the pre-buried pipe 4, so that the end of the pre-buried pipe 4 can be embedded in the annular groove 5, meeting the sealing requirements of the pipe cap 1 on the end of the pre-buried pipe 4.
[0016] In a preferred embodiment, under the construction premise that the pre-buried pipe 4 is a hollow pipe with a cylindrical shape, the horizontal cross-section of the annular groove 5 is designed to be annular; within a horizontal cross-section, the radius of the circle containing the inner wall 502 of the groove is smaller than the radius of the internal cavity of the pre-buried pipe 4; the radial distance between the inner wall 502 of the groove and the outer wall 501 of the groove is greater than the thickness of the pipe wall 401 of the pre-buried pipe 4 to be blocked, and the outer wall 501 of the groove can be sleeved on the outer wall of the pre-buried pipe 4, so that the radius of the circle containing the horizontal cross-section of the outer wall 501 of the groove is greater than the radius of the outer diameter of the pre-buried pipe 4. Further preferably, the pipe cap 1 is a metal pipe cap made of metal.
[0017] Preferably, the pre-buried pipe plugging device includes a handle 2, which is arranged on the pipe cap 1 of the pre-buried pipe plugging device. When the pipe cap 1 is used to plug the end of the pre-buried pipe 4, the handle 2 is held and the annular groove 5 is aligned with the end of the pre-buried pipe 4, so that the end of the pre-buried pipe 4 can be embedded in the annular groove 5, thereby improving construction efficiency. Optionally, the handle 2 is designed to be cylindrical; the cylindrical handle facilitates the installation and removal of the pipe cap 1, further improving the efficiency of workers.
[0018] Preferably, the pre-buried pipe plugging device includes a threaded rod 3, which is used to pass through the annular groove 5 to firmly fix the pipe cap 1 to the end of the pre-buried pipe 4. A threaded hole (not shown in the figure) is arranged on the annular groove 5 of the pre-buried pipe plugging device; the thread on the threaded hole matches the thread on the threaded rod 3; the threaded hole penetrates the outer wall 501 of the groove of the annular groove 5. When in use, after the end of the pre-buried pipe 4 is embedded in the annular groove 5 of the pipe cap 1, the threaded rod 3 is rotated into the threaded hole through its threaded fit, reaches the inside of the annular groove 5, and contacts the outer wall of the pre-buried pipe 4; tighten the threaded rod 3, so that the pipe cap 1 and the end of the pre-buried pipe 4 are firmly fixed by the friction between the threaded rod 3 and the outer wall of the pre-buried pipe 4. Furthermore, the threaded rod can be an L-shaped threaded rod to facilitate construction operations.
[0019] In practice, the threaded hole can also penetrate the outer wall and inner wall of the annular groove at the same time, and an appropriate hole is arranged on the end of the embedded pipe, so that the threaded rod can be screwed in from the outer wall of the groove at the same time, and penetrate the corresponding hole on the embedded pipe to reach the threaded hole on the inner wall of the groove, thereby fixing the pipe cap more firmly and achieving the purpose of sealing.
