[0002] The waterproof treatment of the basement wall casing is very important. If it is not handled properly, it will cause serious water immersion inside the building, thus affecting the service life and safety of the building. At present, waterproof casings are pre-buried in the walls of basement pipelines. The waterproof casing effectively solves the leakage problem between the casing and the concrete, but leakage between the casing and the internal pipeline still occurs from time to time. At present, the internal waterproofing of the casing adopts oil hemp silk + high-strength cement + leak-proof king, but this method has a disadvantage: oil hemp silk looks simple to operate, but it actually requires a certain winding technology, otherwise it is easy to cause uneven sealing around the periphery, resulting in poor sealing.
[0003] In order to solve the problem of "uneven sealing around the internal pipeline resulting in poor sealing", the prior art discloses a waterproof treatment structure for the part where the pipeline passes through the wall, a waterproof casing is reserved on the wall, the pipeline passes through the waterproof casing, a steel plate waterstop ring is welded on the inner wall of the middle part of the waterproof casing, an expansion rubber waterstop strip is bonded between the root of the steel plate waterstop ring and the inner wall of the waterproof casing, and the gap between the pipeline and the waterproof casing is filled with cement asbestos or waterproof mortar; the diameter of the waterproof casing is 100mm larger than the diameter of the pipeline passing through the wall; the thickness of the steel plate waterstop ring is 3mm and the width is 200mm; the cross-section of the expansion rubber waterstop strip is 15×15mm.
[0004] With regard to the above-mentioned related technologies, when a leakage point appears in the internal pipeline inside the waterproof casing passing through the wall, the seeping water will flow in the gap between the waterproof casing and the internal pipeline until the leaking water infiltrates into the cement asbestos or waterproof mortar. At this time, the expansion rubber waterstop strip expands around after absorbing water, resulting in poor sealing and leak-proofing effect. The leaking water can still continue to penetrate through the gap between the rubber expansion waterstop strip and the cement asbestos and the internal pipeline, affecting the waterproof partition effect inside the waterproof casing.

[0039] The embodiments of the present application disclose a water stop ring in a casing and a method of using the water stop ring.
[0040] In a first aspect, an embodiment of the present application discloses a water stop ring in a casing.
[0041] Reference Figure 1 A water stop ring inside a casing includes a limiting ring 1 and an expansion water stop strip 2. There are two limiting rings 1, which are coaxially arranged. The size of the inner hole on the limiting ring 1 is determined according to the size of the internal pipeline 02. The outer diameter of the limiting ring 1 is determined according to the outer diameter of the waterproof casing 01. A accommodating cavity is formed between the two limiting rings 1, and the inner and outer circular sides of the accommodating cavity are both opened; the expansion water stop strip 2 is located in the accommodating cavity, and the expansion water stop strip 2 abuts against the side wall of the limiting ring 1. In the present application, the expansion water stop strip 2 can be any material that expands when exposed to water. In the present embodiment, the expansion water stop strip 2 is preferably an expansion rubber water stop strip.
[0042] Reference Figure 1 In order to control the expansion direction of the expansion waterstop strip 2 when the expansion waterstop strip 2 absorbs water and expands, and thereby achieve the sealing of the gap between the limiting ring 1 and the internal pipeline 02, and the limiting ring 1 and the waterproof casing 01, the inner waterstop ring of the casing also includes a tie fastener 3, which is arranged through the expansion waterstop strip 2, and the tie fastener 3 is connected to the limiting ring 1, which is used to fix the limiting ring 1, thereby controlling the distance between the two limiting rings 1.
[0043] Reference Figure 1 Specifically, the tie-fastening fixture 3 includes a through screw 31 and a fixing nut 32, and the number of the through screw 31 and the fixing nut 32 are both multiple. The through screw 31 is set through the expansion water stop strip 2, and the through screw 31 passes through the limiting ring 1. The axial direction of the through screw 31 is consistent with the axial direction of the limiting ring 1. The fixing nut 32 is threadedly connected to the through screw 31, and the two fixing nuts 32 realize the axial position fixation of a limiting ring 1 compared to the through screw 31; the position of the limiting ring 1 can be fixed by cooperating with the through screw 31 and the fixing nut 32, and the appropriate spacing of the limiting rings 1 can be selected according to the filling quantity of the expansion water stop strip 2, thereby ensuring that the expansion water stop strip 2 can quickly seal the water-permeable gaps after absorbing water and expanding, thereby improving the waterproof partition effect inside the waterproof casing 01.
[0044] Reference Figure 1 In order to further reduce the possibility of leakage water penetrating through the gap between the limiting ring 1 and the penetration screw 31, a sealing gasket 33 made of rubber material is arranged between the limiting ring 1 and the fixing nut 32, and the penetration screw 31 is arranged through the sealing gasket 33. By screwing the fixing nut 32, the sealing gasket 33 can be pressed into the gap between the limiting ring 1 and the penetration screw 31 to complete the sealing and plugging.
[0045] Reference Figure 2The side of the limiting ring 1 away from the expansion water stop strip 2 is filled with hemp silk, and a certain amount of hemp silk is compacted to form a leak-proof layer 4, and the leak-proof layer 4 away from the limiting ring 1 is filled with high-strength cement, and the high-strength cement is solidified to form a fixing layer 5. The leak-proof layer 4 and the fixing layer 5 are both between the waterproof casing 01 and the internal pipeline 02. First, they can serve as the peripheral supplementary reinforcement structure of the waterproof structure inside the waterproof casing 01, and secondly, they can also serve as a limiting structure for the position of the limiting ring 1 inside the waterproof casing 01.
[0046] Reference Figure 3 In order to strengthen the structural strength of the limiting ring 1 and at the same time strengthen the connection reliability with the plugging layer 4, a plurality of reinforcing ribs 6 are welded and fixed on the side of the limiting ring 1 away from the expansion water stop strip 2. The reinforcing ribs 6 are arranged vertically to the limiting ring 1, and the reinforcing ribs 6 are provided with perforations. The reinforcing ribs 6 extend into the plugging layer 4, and the oil linen fiber passes through the perforations.
[0047] The implementation principle of a water stop ring inside a casing in an embodiment of the present application is as follows: a limiting ring 1 is pre-processed according to the inner diameter of the waterproof casing 01 and the outer diameter of the internal pipeline 02, and an expansion water stop strip 2 and a tie-fastening fixture 3 are prepared for standby use; then the two limiting rings 1 are passed through the internal pipeline 02, and then the expansion water stop strip 2 is inserted into and fills the accommodating cavity formed between the two limiting rings 1, and the expansion water stop strip 2 surrounds the circumference of the internal pipeline 02; then the two limiting rings 1 are fixed by the tie-fastening fixture 3, so that the distance between the two limiting rings 1 is fixed to obtain the water stop ring body; then the internal pipeline 02 is passed through the waterproof casing 01, and the auxiliary positioning tooling 7 is used to complete the pushing of the water stop ring body along the forward direction of the internal pipeline 02 until the water stop ring body reaches the inside of the waterproof casing 01. The water-stopping position is preset, and finally, hemp silk is filled on both sides of the water-stop ring body to form a leak-proof layer 4, and then high-strength cement is filled on the side of the leak-proof layer 4 away from the water-stop ring body to form a fixing layer 5. When a leak occurs in the waterproof sleeve 01 itself or the internal pipeline 02 inside the waterproof sleeve 01 that passes through the wall, the seeping water will flow in the gap between the waterproof sleeve 01 and the internal pipeline 02, and then pass through the fixing layer 5 and the leak-proof layer 4 in turn until the leaking water infiltrates the expansion waterstop strip 2. The expansion waterstop strip 2 expands after absorbing water. Since the tie-fastening fixing 3 fixes the distance between the two limiting rings 1, the expansion waterstop strip 2 will expand along the radial direction of the internal pipeline 02, thereby sealing the gap between the waterproof sleeve 01 and the internal pipeline 02, thereby improving the waterproof partition effect inside the waterproof sleeve 01.
