DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0022] Please refer to Figures 1 to 3 The utility model provides a technical scheme: a prefabricated municipal comprehensive pipe gallery, including pipe gallery section 1, the pipe gallery connecting sleeve 2 is connected between adjacent pipe gallery section 1, and the both ends of pipe gallery connecting sleeve 2 are provided with the insertion slot 21 of one end insertion joint connection with pipe gallery section 1, when laying, pipe gallery connecting sleeve 2 acts as two pipe gallery section 1 connecting components, pipe gallery connecting sleeve 2 and pipe gallery section 1 all adopt the structure of inner-embedded square tube outside pouring concrete, under the guidance of insertion slot 21, the assembly of two pipe gallery section 1 is more smooth and fast, and waterproof rubber mat 3 is nested in insertion slot 21, and the role of waterproof rubber mat 3 is water stop, so that the connecting place between pipe gallery connecting sleeve 2 and pipe gallery section 1 is waterproof, and a plurality of connecting parts 4 are connected in pipe gallery connecting sleeve 2, the connecting part 4 and the pipe gallery section 1 of both sides of pipe gallery connecting sleeve 2 are detachably connected, the connecting part 4 is evenly distributed on the inner peripheral wall of pipe gallery connecting sleeve 2, and the role of connecting part 4 is to make pipe gallery section 1 and pipe gallery connecting sleeve 2 be in fastening connection state, wherein, a recess 12 is formed in the both ends of pipe gallery section 1, and waterproof rubber mat 3 is filled in recess 12 after being extruded and deformed.

[0023] Specifically, connecting part 4 includes lead screw 41, lead sleeve 42 and pull plate 43, lead screw 41 is connected on the inner wall of pipe gallery connecting sleeve 2, one end of pull plate 43 is fixedly connected with the inner wall of pipe gallery section 1, and the guide hole 431 of insertion joint with lead screw 41 is formed in pull plate 43, after the one end of lead screw 41 is inserted into guide hole 431, lead sleeve 42 is screwed on the lead screw 41, and then pipe gallery section 1 and pipe gallery connecting sleeve 2 are fastened and connected when lead sleeve 42 extrudes pull plate 43, at this time, waterproof rubber mat 3 in insertion slot 21 is extruded and deformed, and then fills the whole insertion slot 21.

[0024] Further, the inner wall of the pipe gallery connecting sleeve 2 is fixedly connected with a support plate 22, which is welded with the middle part of the support rod 41. This arrangement facilitates the fastening connection of the pipe gallery connecting sleeve 2 and the single pipe gallery section 1.

[0025] In this embodiment, the inner peripheral wall of the pipe gallery section 1 is provided with a clamping groove 11 close to the pipe gallery connecting sleeve 2, and the clamping groove 11 is nested with a sealing rubber strip 5. After the sealing rubber strip 5 is installed, the waterproof performance of the connection between the pipe gallery section 1 and the pipe gallery connecting sleeve 2 is better.

[0026] Further, the inner peripheral wall of the pipe gallery connecting sleeve 2 is provided with a pouring opening 23 close to the top and communicating with the clamping groove 11. After the pipe gallery section 1 and the pipe gallery connecting sleeve 2 are connected, waterproof concrete is injected into the clamping groove 11 through the pouring opening 23 using a pouring gun. Thus, the connection between the pipe gallery section 1 and the pipe gallery connecting sleeve 2 is more stable and reliable, and the waterproof performance is better.

[0027] In this embodiment, the outer wall of the pipe gallery connecting sleeve 2 is fixedly connected with an annular positioning plate 6, and the two sides of the annular positioning plate 6 are welded with positioning plates, and the positioning plates are inserted with anchor rods 61. In specific implementation, positioning holes matched with the anchor rods 61 can be formed in the positioning plates. After the pipe gallery connecting sleeve 2 is laid in the pit, the anchor rods 61 can be used to fix the pipe gallery connecting sleeve 2 in the pit, which has the function of preventing dislocation and movement, thereby ensuring the stable connection of the pipe gallery connecting sleeve 2 and the pipe gallery section 1.

[0028] Working principle: when laying, first place the pipe gallery connecting sleeve 2 in the pit, then insert one end of one pipe gallery section 1 into the insertion slot 21 at one end of the pipe gallery connecting sleeve 2, then manually enter the pipe gallery connecting sleeve 2, use a tool to process a thread sleeve 42 screwed on one end of a lead screw 41, and then tighten them one by one. At this time, the pipe gallery connecting sleeve 2 and the pipe gallery section 1 are fastened and connected. Then, waterproof concrete is poured into the pouring opening 23 using a pouring gun. The waterproof concrete will not leak out due to the blocking action of the sealing rubber strip 5, and will also fill the entire clamping groove 11. After pouring is completed, one pipe gallery connecting sleeve 2 is inserted at the other end of the current pipe gallery section 1, and then the pipe gallery connecting sleeve 2 and the pipe gallery section 1 are fastened and connected in the above manner.
