Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water tank wall waterproofing technology, and in particular relates to a grouting waterproof sleeve for water tank walls. Background Technology
[0002] In waterworks and wastewater treatment projects, inlet pipe holes are installed in the walls of water tanks. A sleeve and a water pipe are installed inside these holes, with the sleeve fitted over the pipe. To prevent wastewater leakage through the gap between the sleeve and the pipe, this gap is typically sealed. Currently, the sealing process usually involves stuffing hemp fiber into the gap and then sealing the ends of the inlet with sealant or similar materials. However, this method primarily considers the density of the hemp fiber filling. If the hemp fiber filling is insufficiently dense, or if the gap between the pipe and the sleeve is uneven, the hemp fiber cannot achieve a tight seal, inevitably leading to a potential leakage problem. Utility Model Content
[0003] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a grouting-type waterproof sleeve for water tank walls. By setting an anti-leakage sealing layer in the annular area between the wall sleeve and the water inlet pipe, the problem of leakage due to incomplete sealing between the traditional wall sleeve and the water inlet pipe can be effectively overcome. A cover plate is set at the end of the wall sleeve, and combined with the shock-absorbing buffer layer and the grouting reinforcement layer between the wall sleeve and the water inlet pipe, the sealing between the wall sleeve and the water pipe is achieved.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a grouting waterproof sleeve for a water tank wall, including a through-wall sleeve installed in the inlet pipe hole of the water tank wall and an inlet pipe installed in the through-wall sleeve and coaxially arranged with the through-wall sleeve, and a leak-proof sealing layer is provided in the annular area between the through-wall sleeve and the inlet pipe.
[0005] The end of the through-wall sleeve installed inside the water tank is the overflow end, and the end of the through-wall sleeve installed outside the water tank is the grouting end. Both the overflow end and the grouting end are equipped with cover plates. The grouting end and the cover plate are integrally formed, and the overflow end and the cover plate are connected by bolts.
[0006] The leak-proof sealing layer includes a shock-absorbing buffer layer arranged circumferentially outside the water inlet pipe and a grouting reinforcement layer arranged circumferentially outside the shock-absorbing buffer layer. The shock-absorbing buffer layer and the grouting reinforcement layer are evenly distributed in the annular area between the wall sleeve and the water inlet pipe.
[0007] The shock-absorbing buffer layer includes a water-stopping section disposed on the outside of the water inlet pipe and located at the end of the water inlet pipe, and a shock-absorbing buffer section disposed on the outside of the water inlet pipe and located between the water-stopping sections.
[0008] The water-stopping section includes a grouting water-stopping ring and an expansion water-stopping ring, both disposed on the outside of the water inlet pipe. The grouting water-stopping ring is arranged circumferentially at the end of the water inlet pipe, and the expansion water-stopping ring is arranged circumferentially between the grouting water-stopping ring and the shock-absorbing buffer section. The outer diameter of the grouting water-stopping ring and the outer diameter of the expansion water-stopping ring are equal.
[0009] The shock-absorbing buffer section includes an asphalt-hemp rope layer disposed outside the water inlet pipe and a steel wire mesh arranged circumferentially outside the asphalt-hemp rope layer; the steel wire mesh has multiple grouting holes, which are arranged along the extension direction of the steel wire mesh.
[0010] Furthermore, the cover plate at the grouting end is provided with a grouting nozzle, and a feed funnel is connected to the grouting nozzle.
[0011] Furthermore, the cover plate of the overflow end is provided with multiple overflow observation holes.
[0012] Furthermore, a pipe clamp is provided on the outside of the cover plate at the overflow end.
[0013] Furthermore, the cover plate is provided with hooks, which are arranged in the annular area and on the side of the cover plate near the water inlet pipe.
[0014] Furthermore, the asphalt sesame oil rope layer is arranged along the circumferential direction of the water inlet pipe; the asphalt sesame oil rope layer is composed of multiple asphalt sesame oil ropes, and the multiple asphalt sesame oil ropes are arranged along the circumferential direction of the water inlet pipe; the asphalt sesame oil ropes are arranged along the extension direction of the water inlet pipe.
[0015] Furthermore, the outer diameters of the wire mesh, the grouting sealing ring, and the expansion sealing ring are all equal; one end of the wire mesh is hung on the cover plate of the grouting end by a hook, and the other end of the wire mesh is hung on the cover plate of the overflow end by a hook.
[0016] Furthermore, the outer side of the through-wall sleeve is coated with colored anti-rust paint.
[0017] This utility model has the following advantages compared with the prior art:
[0018] 1. This utility model effectively overcomes the problem of leakage caused by the non-tight sealing between the wall sleeve and the water inlet pipe in traditional water tanks by setting an anti-leakage sealing layer in the annular area between the wall sleeve and the water inlet pipe; by setting a cover plate at the end of the wall sleeve, and combining the shock-absorbing buffer layer and the grouting reinforcement layer between the wall sleeve and the water inlet pipe, the sealing between the wall sleeve and the water pipe in the water tank is achieved.
[0019] 2. In this utility model, steel wire mesh is used to limit the asphalt sesame oil rope layer, ensuring that the asphalt sesame oil rope layer is close to the outside of the water inlet pipe, so that the vibration of the water inlet pipe can be effectively buffered and weakened; thereby ensuring that long-term vibration of the water inlet pipe will not cause the small gap between the water inlet pipe and the wall sleeve to increase, and ensuring that the pool wall does not leak at this waterproof sleeve.
[0020] 3. The present invention provides multiple grouting holes in the wire mesh to ensure that the grouting material can pass through the wire mesh and enter the internal space of the asphalt hemp rope, thereby ensuring a tight grout filling and improving the waterproof performance of the waterproof sleeve.
[0021] In summary, this utility model effectively overcomes the problem of leakage caused by inadequate sealing between the wall sleeve and the inlet pipe in traditional water tanks by setting an anti-leakage sealing layer in the annular area between the wall sleeve and the inlet pipe; by setting a cover plate at the end of the wall sleeve, and combining it with the shock-absorbing buffer layer and the grouting reinforcement layer between the wall sleeve and the inlet pipe, a sealed seal between the wall sleeve and the water pipe is achieved.

A leak-proof sealing layer is provided in the annular area between the through-wall sleeve 1 and the inlet pipe 2.
[0033] The end of the through-wall sleeve 1 located inside the water tank is the overflow end, and the end of the through-wall sleeve 1 located outside the water tank is the grouting end. Both the overflow end and the grouting end are provided with a cover plate 3. The grouting end and the cover plate 3 are integrally formed, and the overflow end and the cover plate 3 are connected by bolts 5.
[0034] The leak-proof sealing layer includes a shock-absorbing buffer layer arranged circumferentially outside the water inlet pipe 2 and a grouting reinforcement layer 11 arranged circumferentially outside the shock-absorbing buffer layer. The shock-absorbing buffer layer and the grouting reinforcement layer 11 are evenly distributed in the annular area between the wall sleeve 1 and the water inlet pipe 2.
[0035] The shock-absorbing buffer layer includes a water-stopping section disposed on the outside of the water inlet pipe 2 and located at the end of the water inlet pipe 2, and a shock-absorbing buffer section disposed on the outside of the water inlet pipe 2 and located between the water-stopping sections.
[0036] The water-stopping section includes a grouting water-stopping ring 12 and an expansion water-stopping ring 13, both disposed on the outside of the water inlet pipe 2. The grouting water-stopping ring 12 is arranged circumferentially at the end of the water inlet pipe 2, and the expansion water-stopping ring 13 is arranged circumferentially between the grouting water-stopping ring 12 and the shock-absorbing buffer section. The outer diameter of the grouting water-stopping ring 12 and the outer diameter of the expansion water-stopping ring 13 are equal.
[0037] The shock-absorbing buffer section includes an asphalt-hemp rope layer 9 disposed outside the water inlet pipe 2 and a wire mesh 10 arranged circumferentially outside the asphalt-hemp rope layer 9; the wire mesh 10 has a plurality of grouting holes, which are arranged along the extension direction of the wire mesh 10.
[0038] In actual use, by setting an anti-leakage sealing layer in the annular area between the wall sleeve 1 and the water inlet pipe 2, the problem of leakage between the traditional water tank wall wall sleeve and the water inlet pipe due to incomplete sealing can be effectively overcome; by setting a cover plate 3 at the end of the wall sleeve 1, and combining the shock-absorbing buffer layer and the grouting reinforcement layer 11 between the wall sleeve 1 and the water inlet pipe 2, the sealing between the water tank wall wall sleeve and the water pipe can be achieved.
[0039] Among them, the wire mesh 10 is used to limit the asphalt sesame oil rope layer 9 to ensure that the asphalt sesame oil rope layer 9 is close to the outside of the water inlet pipe 2, so that the vibration of the water inlet pipe 2 can be effectively buffered and weakened; thereby ensuring that the vibration of the water inlet pipe 2 for a long time will not cause the small gap between the water inlet pipe 2 and the wall sleeve 1 to increase, and ensuring that the pool wall does not leak at this waterproof sleeve.
[0040] In addition, multiple grouting holes are opened on the wire mesh 10 to ensure that the grouting material can enter the internal space of the asphalt hemp rope through the wire mesh 10, ensuring that the grouting is densely filled and improving the waterproof performance of this waterproof sleeve.

[0045] In actual use, the pipe clamp 15 provided on the outside of the cover plate 3 of the overflow end must be firmly installed before grouting to ensure that the grout will not leak out in large quantities through the gaps and cause pressure loss during grouting.
[0046] like Figure 1 As shown, in this embodiment, the cover plate 3 is provided with a hook 6, which is arranged in the annular area and on the side of the cover plate 3 near the water inlet pipe 2.
