It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] Reference Figures 1 to 6 As shown, the present invention provides an anti-leakage precise positioning device for a drainage pipe, comprising: a supporting sleeve 1, a positioning sleeve 2, and a sealing paste 3.

[0037] Before installing the drain pipe, a hole is first opened on the floor slab according to the installation position of the drain pipe. The size of the hole is larger than the outer diameter of the drain pipe and larger than the outer diameter of the support sleeve. Among them, the inner diameter of the support sleeve 1 is larger than the outer diameter of the positioning sleeve.

[0038] The support sleeve 1 is vertically arranged in the hole of the floor 6. The upper pipe opening of the support sleeve 1 extends outward to form a waterproof flange 11. The floor 6 is supported by the waterproof flange 11. Specifically, the outer edge of the waterproof flange overlaps the floor. The waterproof flange 11 is arranged in a circle along the circumferential direction of the support sleeve 1. The middle part of the waterproof flange 11 is arched upward to form an anti-ridge 10.

[0043] The lower pipe opening of the supporting sleeve 1 extends inward to form a blocking flange 12. The blocking flange 12 is connected to the upper pipe opening of the positioning sleeve 2. An accommodating annular groove is formed between the blocking flange 12 and the inner wall of the supporting sleeve 1.

[0044] The sealing paste 3 is filled in the accommodating ring groove and is used to seal between the drain pipe 7 and the upper end of the positioning sleeve 2 .

[0045] The leakage-proof precise positioning device for a drainage pipe of the present invention further comprises a plurality of tension plates 4 .

[0046] Specifically, in this embodiment, an enlarged diameter hole is formed at the upper part of the hole. The hole diameter of the upper half of the hole gradually changes, that is, the enlarged diameter hole. The inner diameter of the enlarged diameter hole gradually increases from bottom to top. The lower hole opening of the enlarged diameter hole is adapted to the inner diameter of the hole. The tension plate is wedge-shaped. The width of the tension plate gradually increases from bottom to top.

[0047] In this embodiment, the tension plate 4 is embedded between the hole wall of the expanded hole and the support sleeve 1. The tension plate has a vertical side portion and an inclined side portion opposite to each other. The inclination of the inclined side portion of the tension plate is adapted to the inclination of the hole wall of the expanded hole. The inclined side portion is pressed against the hole wall of the expanded hole, and the vertical side portion is pressed against the outer wall of the support sleeve.

[0048] See also Figure 6 As shown, a plurality of tension plates 4 are connected with connecting rods 41. The connecting rods are arc-shaped. The tension plates 4 are detachably mounted with sealing templates 5 for sealing the lower openings of the holes through suspension rods 42.

[0049] Continue reading Figure 6 As shown, a notch 40 is provided on one side of the tension plate 4 facing the support sleeve 1. The outer wall of the support sleeve 1 forms a plug-in block. The plug-in block is detachably inserted into the notch 40.

[0050] Combination Figure 2 As shown, the upper end of the suspension rod 42 is connected to the tension plate 4. The sealing template 5 is provided with a through hole. The lower end of the suspension rod 42 can be movably inserted into the through hole. The lower end of the suspension rod 42 is detachably connected to a support member 43. The support member 43 is supported at the bottom of the sealing template 5.

[0051] In this embodiment, the support member is formed with a threaded hole, the lower end of the suspension rod is formed with an external thread, and the threaded hole of the support frame is screwed to the lower end of the suspension rod.

[0056] S2. Install the sealing template 5 at the lower opening of the hole of the floor slab 6.

[0057] The tension plate is set in the aperture hole so that the suspension rod extends below the lower hole of the hole. The sealing template is attached to the bottom of the floor slab so that the floor slab is sealed at the lower hole of the hole. The lower end of the suspension rod is passed through the perforation of the sealing module and the support is installed so that the sealing template is stably set at the bottom of the floor slab.

[0058] S3, insert the drain pipe 7 into the hole.

[0062] Install the drain pipe at the location of the hole and add the cement mortar prepared in advance to hang the hole. While filling the cement mortar, put the anti-leakage precision positioning device for the drain pipe on the outside of the drain pipe to ensure that the positioning base is sunk into the hole and the bottom surface of the waterproof anti-slope is flush with the upper surface of the floor slab.

[0063] The pre-filled cement mortar is fully filled between the anti-leakage precise positioning device for the drain pipe, the hole wall, and the outer wall of the drain pipe.

[0064] After inserting the drain pipe, fine-tune the four stiffening plates left and right according to the laid lines to accurately position the drain pipe. After positioning, leave it alone and wait for the cement mortar to solidify.

[0065] S7. Fill the sealing paste 3 between the outer wall of the drain pipe 7 and the inner wall of the supporting sleeve 1 and the sealing flange 12 to form an accommodating ring groove, so that the sealing paste 3 is sealed between the drain pipe 7 and the upper end of the positioning sleeve 2.

[0066] After the cement mortar solidifies, apply a layer of sealant evenly on the surface of the drain pipe and the sealing flange to ensure that the sealant can fully cover the drain pipe and the positioning sleeve.

[0067] S8. After the sealing paste 3 solidifies, spray waterproof coating on the outer wall of the waterproof flange 11, the sealing paste 3 and the drain pipe 7 to form a waterproof layer.

[0068] After the sealing paste solidifies, apply polyurethane waterproofing to the surface of the drainage pipe anti-leakage positioning device at the same time.

[0069] After the drainage pipe is installed, conduct a water-tightness test to check for leakage. If leakage is found, handle it in time until it is qualified.

The anti-ridge is formed by the waterproof flange of the supporting sleeve, and the water-retaining and water-collecting sealing structure formed between the drain pipes with the sealing paste can effectively prevent the occurrence of leakage and ensure the normal operation of the building drainage system.

[0072] Since the anti-leakage precise positioning device for the drainage pipe of the present invention can effectively prevent leakage, the maintenance cost caused by the leakage problem is reduced.
