[0033] In this embodiment, when the drainage pipe 1 is waterproofed and installed through the wall, the asphalt cloth waterproof layer 13 can be wrapped and attached to the outer surface of the drainage pipe 1, and then the two waterproof pipe sleeves 2 are combined so that the interiors of the two waterproof pipe sleeves 2 and the drainage pipe 1 are tightly fitted together and fixed together by fasteners 9, and then the fixed waterproof pipe sleeves 2 are installed into the reserved holes of the wall. The square water stop rings 7 on the two waterproof pipe sleeves 2 will perform a preliminary blocking and water stop effect on the reserved holes in the wall, and then the expansion screws 6 on the two water retaining plates 4 are fixed. , the two water retaining plates 4 are firmly fixed on the wall, and then the expansion cement slurry is injected into the reserved hole in the wall through the grouting pipes 10 on both sides of the two water retaining plates 4. By arranging a square water stop ring 7 between the reserved hole in the wall and the drain pipe 1 when the drain pipe 1 is installed, the waterproof effect of the wall can be greatly increased, so that the subsequent drain pipe 1 will have insufficient waterproof effect when in use. Moreover, the device fills the space between the drain pipe 1 and the reserved hole in the wall immediately after the water retaining plates 4 are installed, which greatly shortens the construction time of the waterproof work of the drain pipe 1.
[0034] Embodiment 2, as Figure 1 - Figure 4As shown, both sides of one side of the outer surface of the two waterproof pipe sleeves 2 are fixedly connected with a No. 1 fixing plate 3, and both sides of the other side of the outer surface of the two waterproof pipe sleeves 2 are fixedly connected with a No. 2 fixing plate 11. Fixing holes 14 are opened on both sides of the four No. 1 fixing plates 3. No. 2 sealing pads 12 are arranged on both sides of the two waterproof pipe sleeves 2. Fasteners 9 are threadedly connected inside the four fixing holes 14. Expansion screws 6 are threadedly connected on both sides of the two water retaining plates 4. A waterproof material layer 8 is arranged on the outer surface of the drain pipe 1, and a No. 1 sealing pad 5 is arranged on one side of the two water retaining plates 4.
[0035] In this embodiment, by providing a waterproof material layer 8 on the outside of the water retaining plate 4, the drainage pipe 1 can be installed to block and fill the gaps between the water retaining plate 4, the wall and the drainage pipe 1, so that the waterproof effect of the device during use is better, and the waterproof material layer 8 is in a truncated cone shape, and the waterproof material layer 8 wraps the outer surface of the drainage pipe 1. Through this method, the waterproof effect of the drainage pipe 1 can be further optimized.
[0036] Working principle: When waterproofing the drain pipe 1, first wrap its asphalt cloth waterproof layer 13 around the outer surface of the drain pipe 1. After the two are tightly fitted, merge the two waterproof pipe sleeves 2 so that the insides of the two waterproof pipe sleeves 2 are tightly fitted with the drain pipe 1 and fixed together by fasteners 9. Then install the fixed waterproof pipe sleeves 2 into the reserved holes in the wall. The square water stop rings 7 on the two waterproof pipe sleeves 2 will perform a preliminary blocking and water-stopping effect on the reserved holes in the wall. Then, fix the two water baffles 4 with expansion screws 6, and firmly fix the two water baffles 4 on the wall. Then, inject the expanded cement slurry into the reserved holes in the wall through the grouting pipes 10 on both sides of the two water baffles 4, so that the expanded cement slurry fills the gaps in the reserved holes in the wall. Then, use the waterproof material layer 8 to fill and block the water baffles 4, the wall and the outside of the drain pipe 1. The shape of the waterproof material layer 8 is truncated cone.
