[0004] The existing rigid waterproof casing leakage plugging equipment will cause leakage problems in the casing that has been sealed and is usually watertight, and even damage the original plugging, causing groundwater ingress problems when the groundwater pressure on the outer wall is too high. Summary of the invention

[0005] The purpose of the present invention is to solve the following shortcomings in the prior art: the existing rigid waterproof casing leakage sealing equipment, when the groundwater pressure on the outer wall is too high, the sealed casing that is usually watertight will leak at this time, and even destroy the original seal, causing groundwater ingress problems, and a rigid waterproof casing leakage sealing device and construction method are proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A rigid waterproof casing leakage plugging device comprises a wall and a second screw rod, a plurality of the second screw rods are arranged in a ring array on the wall, and the second screw rods are slidably connected to the wall;

[0008] The wall is provided with a mounting hole, a pipe is slidably connected in the mounting hole, a closing component is installed on the wall, and the closing component includes a water-stop rubber ring, a water-stop pressure plate, a waterproof sleeve, a gasket, and a nut. The water-stop rubber ring is sleeved on the pipe, the water-stop pressure plate is slidably connected to the second screw rod, a plurality of gaskets are respectively slidably connected to the second screw rod, the nut is threadedly connected to the second screw rod and is located on one side of the gasket, and the waterproof sleeve is sleeved on the pipe and is located on the side of the wall away from the water-stop rubber ring;

[0009] A fixing component is provided between the two water-stop pressure plates, and the fixing component includes an auxiliary pressure plate, a first screw rod, a through hole, a limit plate, and an extrusion block. The auxiliary pressure plate is arranged on one side of the water-stop pressure plate, the first screw rod is slidably connected to the auxiliary pressure plate, the limit plate is slidably connected to the auxiliary pressure plate, and the two extrusion blocks are both slidably connected to the auxiliary pressure plate.

[0010] Preferably, the closing component further comprises a groove, and the groove is arranged in an annular shape on the inner side wall of the water stop pressure plate.

[0011] Preferably, the fixing component further comprises a through hole, a plurality of limiting holes in an equidistant array are formed on the auxiliary pressing plate, and the through holes are arranged on the limiting plate.

[0012] Preferably, two sleeves are fixedly connected to the water-stop pressure plate, and a piston is slidably connected inside the sleeve.

[0013] Preferably, a push rod is slidably connected to one side wall of the sleeve, and one end of the push rod is fixedly connected to the piston.

[0014] Preferably, a spring is provided at one end of the push rod away from the piston, and one end of the spring away from the push rod is fixedly connected to the sleeve.

[0015] Preferably, an airbag is fixedly connected in the groove, and an air pipe is fixedly connected between the airbag and the sleeve.

[0016] Preferably, one end of the waterproof sleeve is fixedly connected to the wall and is arranged between the plurality of second screw rods, and a sealing filler is provided in the waterproof sleeve.

[0017] A construction method for a rigid waterproof casing leakage plugging device comprises the following steps:

[0018] S1: Place the water stop pressure plate close to the wall and around the pipe, set eight threaded holes, mark the wall according to the positions of the bolt holes, remove the water stop pressure plate after marking and drill holes on the wall, then clean the holes and place the second screw;

[0019] S2: Place the waterproof rubber ring along the circumference of the pipe, ensuring that the waterproof rubber ring is close to the outer surface of the pipe and slightly wider than the waterproof casing. Since the waterproof rubber ring is divided into two layers, the openings of the two layers of waterproof rubber rings should be placed facing each other and must not be located at the junction of the waterproof pressure plate. The two layers of waterproof rubber rings and the openings of the rubber rings are bonded with special rubber glue to ensure that there is no leakage at the junction. After the bonding is completed, the next step can be carried out;

Place the gasket and tighten the nut to completely press the waterstop rubber ring onto the wall to complete the installation of the device. If multiple pipelines are installed, attention should be paid to the pipeline spacing to meet the installation space requirements of the waterstop pressure plate. When the space is insufficient and the spacing is close, the waterstop pressure plate can be partially cut. If it meets the wall drilling and fixing requirements after cutting, it can be fixed directly. Otherwise, use an auxiliary pressure plate to cooperate with the waterstop pressure plate to fix it to the wall through the first screw.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The sealing rubber ring is pressed tightly between the pipe and the waterproof casing mainly through the water stop pressure plate to block the leakage position and achieve the blocking of leakage.

[0023] 2. When the sleeve continues to move through the water stop pressure plate, the push rod is limited by the wall, causing the piston to slide in the sleeve and squeeze the gas in the sleeve to be transmitted to the airbag through the air pipe. As the gas in the airbag increases, the size of the airbag becomes larger, so that the inner wall of the airbag fits with the outer surface of the pipe, thereby increasing the sealing degree of the pipe by using the airbag.

[0024] 3. When the water stop pressure plate cannot be effectively fixed in some confined spaces, auxiliary pressure plates can be used for auxiliary fixation. The type of auxiliary pressure plates can be adjusted according to needs.

[0025] 4. When the limit plate moves, the two extrusion blocks can be squeezed away from each other, so that the extrusion blocks can fit the surface of the pipe, which can have a limiting effect on the pipe, thereby preventing the pipe from shifting. Then, the external pin is inserted into the limiting hole on the auxiliary pressure plate through the through hole to fix the limit plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] A mounting hole is provided on the wall 1, in which a pipe 14 is slidably connected. A closing component is installed on the wall 1, and the closing component includes a water-stop rubber ring 15, a water-stop pressure plate 2, a waterproof sleeve 13, a gasket 7, and a nut 4. The water-stop rubber ring 15 is sleeved on the pipe 14, the water-stop pressure plate 2 is slidably connected to the second screw rod 12, and a plurality of gaskets 7 are respectively slidably connected to the second screw rod 12. The nut 4 is threadedly connected to the second screw rod 12 and is located on one side of the gasket 7. The waterproof sleeve 13 is sleeved on the pipe 14 and is located on the side of the wall 1 away from the water-stop rubber ring 15. One end of the waterproof sleeve 13 is fixedly connected to the wall 1 and is arranged on a plurality of second Between the screw rods 12, a sealing filler is provided in the waterproof sleeve 13, and the water-stop rubber ring 15 is divided into two halves. The water-stop rubber ring 15 is composed of two flange gaskets (the size specifications refer to the national standard flange gasket) that match the specifications of the pipe 14. For easy installation, the two flange gaskets are respectively cut with a fracture. After the flange gaskets are installed on the pipe 14, glue is used to bond the flange gaskets and the fracture positions. The closing component also includes a groove 6, which is arranged in a ring shape on the inner wall of the water-stop pressure plate 2. The water-stop rubber ring 15 is mainly pressed tightly between the pipe 14 and the waterproof sleeve 13 through the water-stop pressure plate 2 to seal the leakage position and achieve sealing of the leakage.

[0037] Two sleeves 10 are fixedly connected to the waterstop pressure plate 2, and a piston 9 is slidably connected inside the sleeve 10. A push rod 8 is slidably connected to one side wall of the sleeve 10, and one end of the push rod 8 is fixedly connected to the piston 9. A spring is provided at the end of the push rod 8 away from the piston 9, and the end of the spring away from the push rod 8 is fixedly connected to the sleeve 10. An air bag 16 is fixedly connected in the groove 6, and an air pipe 11 is fixedly connected between the air bag 16 and the sleeve 10. When the sleeve 10 continues to move driven by the waterstop pressure plate 2, the push rod 8 is limited by the wall 1, causing the piston 9 to slide in the sleeve 10 and squeeze the gas in the sleeve 10 to be transmitted to the air bag 16 through the air pipe 11. As the gas in the air bag 16 increases, the size of the air bag 16 becomes larger, so that the inner wall of the air bag 16 fits with the outer surface of the pipe 14, thereby using the air bag 16 to increase the sealing degree with the pipe 14.

[0038] A fixing component is provided between the two water-stop pressure plates 2, and the fixing component includes an auxiliary pressure plate 3, a first screw rod 5, a through hole 17, a limit plate 18, and an extrusion block 19. The auxiliary pressure plate 3 is arranged on one side of the water-stop pressure plate 2, the first screw rod 5 is slidably connected to the auxiliary pressure plate 3, the limit plate 18 is slidably connected to the auxiliary pressure plate 3, and the two extrusion blocks 19 are both slidably connected to the auxiliary pressure plate 3. The fixing component also includes a through hole 17. A plurality of limit holes in an equidistant array are opened on the auxiliary pressure plate 3, and the through hole 17 is arranged on the limit plate 18. When the water-stop pressure plate 2 cannot be effectively fixed in a partially confined space, the auxiliary pressure plate 3 can be used for auxiliary fixation, and the type of the auxiliary pressure plate 3 can be adjusted according to demand.

[0039] A construction method for a rigid waterproof casing leakage plugging device comprises the following steps:

[0040] S1: Place the water stop pressure plate 2 close to the wall 1 and around the pipe 14, set eight threaded holes, mark the wall 1 according to the positions of the bolt holes, remove the water stop pressure plate 2 after marking and drill holes on the wall 1, then clean the holes and place the second screw rod 12;

[0041] S2: Place the waterproof rubber ring 15 around the pipe 14 to ensure that the waterproof rubber ring 15 is close to the outer surface of the pipe 14 and is slightly wider than the waterproof sleeve 13. Since the waterproof rubber ring 15 is divided into two layers, the opening positions of the two layers of waterproof rubber rings 15 should be placed facing each other and must not be located at the joint position of the waterproof pressure plate 2. The two layers of waterproof rubber rings 15 and the opening positions of the rubber rings are bonded with special rubber glue to ensure that there is no leakage at the joint position. After the bonding is completed, the next step can be carried out;

[0042] S3: Align the water-stop pressure plate 2 matching the pipe 14 with the bolt hole and press it against the pipe 14. Place the gasket 7 and tighten the nut 4 to completely press the water-stop rubber ring 15 onto the wall 1 to complete the installation of the device. If multiple pipes 14 are installed, it should be noted that the spacing between the pipes 14 can meet the installation space requirements of the water-stop pressure plate 2. When the space is insufficient and the spacing is close, the water-stop pressure plate 2 can be partially cut. If it meets the requirements of wall 1 drilling and fixing after cutting, it can be fixed directly. Otherwise, use the auxiliary pressure plate 3 to cooperate with the water-stop pressure plate 2 to fix it to the wall 1 through the first screw 5.

[0043] In the present invention, the water stop pressure plate 2 is placed close to the wall 1 and around the pipe 14, eight threaded holes are set, and the wall 1 is marked according to the positions of the bolt holes. After marking, the water stop pressure plate 2 is removed and holes are punched on the wall 1, and then the holes are cleaned and the second screw 12 is placed. When the water stop pressure plate 2 is close to the wall 1, the push rod 8 first contacts the wall 1, and then the sleeve 10 is driven to continue to move by the water stop pressure plate 2. The push rod 8 is limited by the wall 1, causing the piston 9 to slide in the sleeve 10 and squeeze the gas in the sleeve 10 to be transmitted to the air bag 1 through the air pipe 11. 6, the size of the airbag 16 increases as the gas increases, so that the inner wall of the airbag 16 fits with the outer surface of the pipe 14, thereby utilizing the airbag 16 to increase the sealing degree with the pipe 14, and placing the waterproof rubber ring 15 along the circumference of the pipe 14 to ensure that the waterproof rubber ring 15 is close to the outer surface of the pipe 14 and is slightly wider than the waterproof sleeve 13. Since the waterproof rubber ring 15 is divided into two, the opening positions of the two layers of waterproof rubber rings 15 should be placed facing each other and must not be located at the combined position of the waterproof pressure plate 2. The two layers of waterproof rubber rings 15 and the opening positions of the rubber rings are bonded with special rubber glue to ensure that there is no leakage at the combined position.

[0044] Align the water-stop pressure plate 2 matched with the pipe 14 with the bolt hole and press it against the pipe 14, place the gasket 7 and tighten the nut 4, completely press the water-stop rubber ring 15 onto the wall 1, and complete the installation of the device. If multiple pipes 14 are installed, it should be noted that the spacing between the pipes 14 can meet the installation space requirements of the water-stop pressure plate 2. When the space is insufficient and the spacing is close, the water-stop pressure plate 2 can be partially cut. If it meets the requirements of drilling and fixing the wall 1 after cutting, it can be fixed directly. Otherwise, use the auxiliary pressure plate 3 to cooperate with the water-stop pressure plate 2 through the first A wire rod 5 is fixed to the wall 1, and then the limit plate 18 is pushed to move. Since the end of the limit plate 18 close to the extrusion block 19 is arranged in a triangular shape, the two extrusion blocks 19 can be squeezed away from each other when the limit plate 18 moves, so that the extrusion block 19 can fit with the surface of the pipe 14, and can have a limiting effect on the pipe 14, thereby preventing the pipe 14 from deviating. Then the external pin is inserted into the limiting hole on the auxiliary pressure plate 3 through the through hole 17 to achieve the fixing effect of the limit plate 18.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
