Description

Technical Field

[0001] The invention relates to the technical field of municipal engineering, and in particular to a waterproof underground pipe gallery. Background Art

[0002] In today's urban infrastructure, underground pipe corridors play a vital role. Underground pipe corridors concentrate engineering pipelines such as electricity, communications, heating, water supply and drainage, and gas, which can effectively reduce the construction and laying of various engineering pipelines. In order to facilitate the manufacture and construction of pipe corridors, prefabricated pipe corridors have emerged. This type of pipe corridor is composed of several single-section pipe corridors, and the joints of the pipe corridors need to be sealed. Most pipe corridors are filled with waterproof fillers in the joints through grouting ports to achieve a waterproof effect.

[0003] For example, the patent with the authorization announcement number CN112343084B proposes a waterproof underground pipe gallery, which injects polyurea resin glue into the rectangular channel through the grouting port and the grouting hole, and then seals the grouting port to achieve water leakage control. However, the grouting port is set vertically, and during the filling process, the waterproof filler has fluidity. During the filling process, it is difficult for the staff to judge whether the waterproof filler fills the joints, resulting in the waterproof filler being difficult to fully cover the joints, the waterproof filler is not filled tightly, and the waterproof effect is reduced. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a waterproof underground pipe gallery to solve the above-mentioned problems.

[0005] Based on the above-mentioned purpose, the present invention provides a waterproof underground pipe gallery, including: a pipe body, a connecting convex ring, a connecting groove and a sealing plug; matching connecting convex rings and connecting grooves are respectively provided at both ends of the pipe body, an annular mounting groove is provided on the inner surface of one end of the pipe body provided with the connecting groove, and a filling port that passes through to the outside of the pipe body is provided on the side wall of the annular mounting groove close to the end face of the pipe body; a first filling groove and a first annular groove are respectively provided on the end face of the pipe body provided with the filling port, the first filling groove is located on the side of the filling port close to the inner wall of the pipe body, the first annular groove is located on the side of the first filling groove close to the inner wall of the pipe body, and the first annular groove, the first filling groove and the filling port are communicated; a flow groove is provided on the other end face of the pipe body at a position opposite to the filling port, a second filling groove is provided at a position opposite to the first filling groove, and a second annular groove is provided at a position opposite to the first annular groove; a sealing plug is provided to seal the filling port on the inner wall of the annular mounting groove.

[0006] Compared with the prior art, the present invention has the following beneficial effects: the filling port is arranged horizontally, and the waterproof filler is filled through the filling port. The waterproof filler flows into the sealing cavity composed of the first annular groove and the second annular groove after passing through the filling cavity composed of the first filling slot and the second filling slot. When the waterproof filler fills the sealing cavity, it will overflow from the horizontal filling port. At this time, the waterproof filler has completely covered the joint between the two adjacent tube bodies. Therefore, it is ensured that the sealing cavity is filled with the waterproof filler and the waterproof filler is filled tightly, thereby improving the waterproof effect.

[0007] Furthermore, the device also includes a connecting plate and a bolt. The connecting plate is an L-shaped structure. The connecting plate is connected to one end of the pipe body provided with a connecting groove.

[0016] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown, a waterproof underground pipe gallery proposed by the present invention is composed of a pipe body 1, a connecting convex ring 2, a connecting groove 3, a sealing plug 4, a restraining plate 14, a limiting rod 15 and an operating rod 16. Matching connecting convex rings 2 and connecting grooves 3 are respectively provided at both ends of the pipe body 1. The connecting convex ring 2 is an annular structure protruding outward at the outer edge of one end of the pipe body 1, and the connecting groove 3 is an annular groove structure opened at the outer edge of the other end of the pipe body 1. The connecting convex ring 2 and the connecting groove 3 match each other, so that the connecting convex rings 2 and the connecting grooves 3 of adjacent pipe bodies 1 can be spliced ​​together.

[0018] An annular installation groove 5 is provided on the inner surface of one end of the tube body 1 provided with the connecting groove 3, and a filling port 6 penetrating to the outside of the tube body 1 is provided on the side wall of the annular installation groove 5 close to the end face of the tube body 1. A first filling groove 7 and a first annular groove 8 are respectively provided on the end face of the tube body 1 provided with the filling port 6, the first filling groove 7 is located on the side of the filling port 6 close to the inner wall of the tube body 1, and the first annular groove 8 is located on the side of the first filling groove 7 close to the inner wall of the tube body 1, and the first annular groove 8, the first filling groove 7 and the filling port 6 are communicated. A flow groove 9 is provided on the other end face of the tube body 1 at a position opposite to the filling port 6, and a second filling groove 10 is provided at a position opposite to the first filling groove 7, and a filling cavity is formed between the first filling groove 7 and the second filling groove 10. A second annular groove 11 is provided on the other end face of the tube body 1 at a position opposite to the first annular groove 8, and a sealing cavity is formed between the first annular groove 8 and the second annular groove 11. The first filling groove 7 has a rounded corner at one end connected to the filling port 6, and the second filling groove 10 has a rounded corner at one end connected to the circulation groove 9. Thus, the end of the filling cavity forms a funnel-shaped structure, which facilitates the waterproof filler to flow into the sealing cavity.

[0019] The filling port 6 located on the inner wall of the annular mounting groove 5 is sealed with a sealing plug 4 for sealing the filling port 6. One end of the constraint plate 14 is hinged on the top surface of the annular mounting groove 5, and the other end of the constraint plate 14 is provided with a sliding cavity, in which a limit rod 15 is slidably connected. A plug hole is provided on the connecting plate 12 opposite to the end of the limit rod 15, and the end of the limit rod 15 is plugged into the plug hole. One side of the constraint plate 14 is in contact with the sealing plug 4, and the other side of the constraint plate 14 is provided with a sliding groove, in which an operating rod 16 is slidably connected, and the operating rod 16 is connected to the limit rod 15.

[0020] The annular mounting groove 5 is connected with a number of evenly distributed connecting plates 12, and the connecting plates 12 are L-shaped structures. The connecting plate 12 is connected to one end of the pipe body 1 provided with the connecting groove 3, and the inner surface of the connecting plate 12 is respectively in contact with the side wall of the annular mounting groove 5 and the inner wall of the pipe body 1, and the end of the connecting plate 12 extends out of the pipe body 1. The connecting plate 12 ensures that the connecting convex ring 2 and the connecting groove 3 of the two adjacent pipe bodies 1 retain steam, thereby avoiding displacement and misalignment during the connection process. The bolt 13 passes through the connecting plate 12 and the side wall of the annular mounting groove 5 in sequence and extends out of the pipe body 1. A number of threaded holes are provided on the end surface of the pipe body 1 at one end provided with the connecting convex ring 2, and the positions of the threaded holes correspond to the positions of the bolts 13. The bolts 13 are used to fix the connecting plate 12 on the one hand, and to connect the two adjacent pipe bodies 1 together on the other hand. Sealing gaskets 17 are respectively connected to the two end surfaces of the pipe body 1, and the position of the sealing gasket 17 avoids the filling port 6, the circulation groove 9, the first filling groove 7, the second filling groove 10, the first annular groove 8 and the second annular groove 11.

[0021] Usage process: dock the two tube bodies 1. After docking, tighten the bolts 13 to connect the two tube bodies 1 together. After ensuring that the filling port 6 is located directly above, pass the waterproof filler through the filling port 6 (polyurea resin glue can be used). The waterproof filler flows along the filling port 6 and the circulation groove 9 into the filling cavity formed by the first filling groove 7 and the second filling groove 10, and then flows through the filling cavity into the sealed cavity formed by the first annular groove 8 and the second annular groove 11. When the waterproof filler begins to overflow from the filling port 6, it means that the waterproof filler has filled the sealed cavity. At this time, the filling port 6 can be blocked with the sealing plug 4.

[0022] Rotate the constraint plate 14 so that the constraint plate 14 is in a vertical state. When the constraint plate 14 is in a vertical state, the limit rod 15 slides downward along the sliding cavity under the action of its own gravity, so that the limit rod 15 is inserted into the plug hole, thereby realizing the rotation limit of the constraint plate 14. At this time, the constraint plate 14 blocks the sealing plug 4, effectively preventing the sealing plug 4 from falling off. When the sealing plug 4 needs to be removed, the staff can slide the operating rod 16 upward, and the operating rod 16 pulls the limit rod 15 out of the plug hole to release the rotation limit of the constraint plate 14. Rotating the constraint plate 14 releases the limit on the sealing plug 4, and the sealing plug 4 can be directly removed.

[0023] The structure proposed by the present invention is suitable for underground pipe galleries with large pipe diameters, and the waterproof filler is ensured to fully cover the joint between two adjacent pipe bodies 1 through the horizontally arranged filling port 6. Thus, it is ensured that the sealed cavity is filled with the waterproof filler and the waterproof filler is filled tightly, thereby improving the waterproof effect.

[0024] The embodiments of the present invention are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
