Pipe segment connection method

Abstract

This invention discloses a method for segmented pipe connection. It involves inserting an extended outer casing (significantly longer than the standard casing) and a standard pipe or extended inner casing into a continuous connection point. Even after stretching the standard or normal connection distance or length at the joint, the connection remains securely attached, preventing slippage. This extended stretch connection or extended combination connection fully utilizes the length difference between the extended outer casing and inner casing combination and the standard outer casing and inner casing combination, preventing slippage while ensuring convenient connection. This method is suitable for segmented pipe connection between floors, and is particularly suitable for the replacement and maintenance of partial pipe sections, making pipe connection more convenient and flexible.

Description

Technical Field

[0001] This invention relates to the field of pipeline anti-seepage interface engineering technology, and in particular to a partial pipeline replacement and repair or segmented connection technology. Background Technology

[0002] For a long time, connecting pipe sections or replacing and repairing parts of pipes has been extremely difficult, involving high construction difficulty, high costs, and time and labor. Furthermore, when pipes pass through walls, especially floor slabs, the difficulty of preventing seepage between the pipes and the walls or floors is even greater, making construction and repair challenging, and ensuring quality control of the waterproofing project during construction is also difficult.

[0003] Therefore, how to provide a pipe segment connection method or device that is simple in structure, easy to install, and has good anti-seepage effect has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a method for connecting pipe segments. The system has a simple structure, is easy to install, and has good waterproofing and drainage effects.

[0005] The present invention provides a method for connecting pipe segments, which uses an extended outer sleeve interface with a significantly longer outer sleeve or an extended outer sleeve interface on a standard pipe as the extended outer sleeve connection interface, and uses an interface of standard pipe or inner sleeve with a length significantly longer than the normal inner sleeve as the extended inner sleeve interface; making full use of the length difference between the extended outer sleeve and inner sleeve combination and the standard outer sleeve and inner sleeve combination, both preventing interface slippage and facilitating connection. During installation, first insert the extended inner tube of the extended inner tube into the extended outer tube of the extended outer tube connection interface to form an anti-slip extended stretch interface or extended combination connection interface that does not slip off even after stretching the joint distance or length of the standard or normal interface; then align the port of the extended combination connection interface with the port of the preceding pipe; finally, stretch the extended inner tube or extended outer tube interface of the extended combination connection interface outwards, tightly fitting the standard outer tube of the extended inner tube interface onto the preceding pipe, or inserting the standard inner tube interface of the extended outer tube interface into the standard interface or standard outer tube interface of the preceding pipe, so that the extended inner tube portion of the extended combination connection interface moves outwards within the extended outer tube, but cannot be completely pulled out. Preferably, it fully utilizes the length difference between the extended outer tube and inner tube combination and the standard outer tube and inner tube combination, preventing interface slippage while facilitating connection. This method is suitable for segmented pipe connections between floors, and is particularly suitable for the replacement and maintenance of partial pipes, making pipe connections more convenient and flexible.

[0006] Preferably, it involves processing and manufacturing an outer sleeve interface with a significantly longer outer sleeve joint, or setting a significantly longer outer sleeve interface on a standard pipe for use as an extended outer sleeve connection.

[0007] Preferably, it is a process that manufactures an interface for an extended internal insertion tube, with the length of the internal insertion tube being significantly longer than that of a normal internal insertion tube.

[0008] Preferably, it is a connection method in which the inner interface of the upper pipe is directly inserted into the outer sleeve interface of the lower pipe or interface.

[0009] Preferably, a sleeve

[32] is installed in the existing vertically installed pipe interface, the upper end of the sleeve

[0010] Preferably, the pipe interface or extended combination connection interface is provided with two non-wetting annular or cylindrical surfaces that can tightly overlap or fit together. Alternatively, a flexible non-wetting surface ring or non-wetting surface material that densely fills the interface gap is provided between the non-wetting surfaces of the overlapping part of the pipe interface; or a flexible non-wetting surface ring that can deform laterally and fit tightly against the inner and outer walls of the interface is provided between the annular gaskets or steps that fasten or abut the two pipe walls at the interface.

[0011] Preferably, a pipe interface locking mechanism is installed at the pipe interface to prevent the two pipes from moving or slipping off each other.

[0012] Preferably, the locking mechanism includes: setting a limiting device of just the right length at the corresponding displacement between the two outer tubes of the extended inner insertion interface and the extended outer tube interface after extraction, and fixing and restricting the movement of the interface to prevent the extended inner insertion interface and the extended outer tube interface from continuing to move relative to each other; or setting one or more openings along the longitudinal direction of the pipe wall at the end of the outer layer interface of the pipe, setting an anti-slip device on the pipe interface, and locking the opening of the pipe interface with fasteners or devices on the outer wall of the outer layer interface of the pipe; or setting a flexible ring or gasket between the locking mechanisms of the pipe interface; or setting a threaded end at the complete circular pipe interface, setting an anti-slip gasket at the port between the interfaces, and the locking nut with a retaining ring, the retaining ring being able to prevent the anti-slip gasket from moving outward.

[0013] Preferably, the anti-slip device is a locking combination of one or more interlocking or meshing annular protrusions, retaining rings, or steps and annular concave rings fixedly provided on the inner and outer walls between the pipe interfaces; or a combination of one or more mutually unidirectionally locking combinations composed of pairs of annular protrusions, retaining rings, or steps; or a recessed annular fastening concave ring is provided at the corresponding position on the inner and outer walls of the pipe interface, and an annular fastening ring matching the fastening concave ring is provided in the fastening concave ring; or annular wedge-shaped openings or annular patterns that can interlock are transversely machined on the inner and outer walls of the interface locking point; or the inner and outer walls of the interface locking point are directly machined into a rough surface, or an uneven rough surface, or anti-loosening or anti-slip barbs that interlock with each other; or annular anti-slip pads or rigid anti-slip pieces or anti-slip pads with sharp protrusions that can be rolled up are provided between the surfaces of the interface locking point.

[0014] Preferably, the limiting device may be a circular ring retaining ring, or an open-ring circular ring retaining ring, or a pipe wall longitudinally broken, or a rolled plate, or one or more straight rods or blocks.

[0015] Preferably, at least two surfaces of the pipe interface that fit together or overlap each other are provided with annular non-wetting surfaces that can fit tightly together.

[0016] The pipe segment connection method is a connection method in which the inner interface of the upper pipe is directly inserted into the outer sleeve interface of the lower pipe or the outer sleeve interface of the interface.

[0017] The method of segmented pipe connection is to set a flexible non-wetting surface ring [3] or non-wetting surface material that fills the gap between the non-wetting surfaces of the overlapping parts of the pipe interface; or to set a non-wetting surface sealing gasket

[11] between the non-wetting surface circular ring

[10] outside the hole [2] port and the locking non-wetting surface of the pipe or pipe interface [4] step

[13] or fastening cover

[14] pressure plate

[15] ; or to set a flexible non-wetting surface ring [3] that can deform laterally and fit tightly against the inner and outer walls of the interface between the annular gasket or step that is fastened or close to each other at the interface.

[0018] The method of segmented connection of the pipe is to process the surface of the pipe or pipe interface below the outlet side of the pipe interface overlap into a hydrophilic surface [5] or add a layer of hydrophilic material, and process the lower surface of the hole [2] or the outer sleeve interface into an annular non-wetting surface. The hydrophilic surface [5] or the hydrophilic material will absorb the leaking water flow and let it flow downward along the outer wall of the pipe or pipe interface, preventing the leaking water flow from wetting the pipe arbitrarily.

[0019] A slope with a suitable gradient is set on the pipe wall below the interface, with one or more hydrophilic surfaces or materials alternating with non-wetting surfaces and all overlapping or superimposing with the pipe wall. A drainage band

[22] is set at the lowest point of the hydrophilic slope, separated from the pipe wall and hanging down. A water flow collection and discharge system is set below the end of the drainage band

[22] .

[0020] A flexible hydrophilic ring

[24] that can fully contact the inner and outer walls of the interface is sandwiched in the middle of the non-wetting surface ring, or a strip or ring-shaped hydrophilic drainage band [8] is filled with a flexible hydrophilic material and led out. The drainage band [8] extends upward from the non-wetting surface ring [3] and the pipe or pipe interface [4] to the upper edge of the non-wetting surface ring [3] or waterproof ring [7] on the upper surface of the floor slab [1] or the outer sleeve wall.

[0021] The pipe segment connection method involves setting a pipe interface locking mechanism at the pipe interface to prevent the two pipes between the interfaces from moving or slipping off each other.

[0022] The locking mechanism is to provide one or more openings

[31] along the longitudinal direction of the pipe wall at the end of the outer layer interface [4] of the pipe, and to provide an anti-slip device for the pipe interface, and to lock and close the openings

[31] of the pipe interface on the outer wall of the outer layer interface [4] with fasteners or devices.

[0023] The anti-slip device is a combination of one or more mutually matching or interlocking annular protrusions

[30] , retaining rings or steps and annular concave rings fixedly installed on the inner and outer walls between the pipe interfaces, or a combination of one or more mutually unidirectional locking composed of annular protrusions, retaining rings or steps.

[0024] Alternatively, a recessed annular fastening recess can be installed at the corresponding position on the inner and outer walls of the pipe interface, and an annular fastening ring matching the fastening recess can be installed in the fastening recess.

[0025] Alternatively, the inner and outer walls of the interface locking point can be transversely machined with interlocking annular wedge-shaped openings or annular patterns, or the inner and outer walls of the interface locking point can be directly machined into a rough surface, or an uneven rough surface, or anti-loosening or anti-slip barbs that interlock with each other.

[0026] Alternatively, an annular anti-slip pad or a rigid anti-slip sheet or anti-slip pad with sharp protrusions that can be rolled up can be provided between the surfaces of the interface locking point;

[0027] Flexible rings or gaskets are installed between the pipe interface locking mechanisms.

[0028] A threaded joint is installed at the complete circular pipe interface, and an anti-slip washer is installed at the port between the interfaces. The locking nut has a retaining ring, which can prevent the anti-slip washer from moving outward.

[0029] The segmented connection method of the pipeline is to combine the extended outer tube of the extended outer tube interface with the extended inner tube of the extended inner tube interface to form an anti-detachment stretching interface that does not slip off after the interface is stretched to the standard or normal interface joint distance or length. A limiting device is set at the stretching point of the anti-detachment stretching interface and fixed to restrict the movement of the interface. The limiting device is a circular retaining ring, or an open standard pipe, or a flexible plate.

[0030] A sleeve

[32] is installed in the existing vertically installed pipe interface. The upper end of the sleeve

[32] is tightly fitted or sealed to the interface step above the existing pipe interface, and the lower end of the sleeve

[32] can extend into the pipe

[18] in the lower interface.

[0031] The method of segmented connection of the pipeline is to set a step

[13] larger than the hole [2] or the outer sleeve hole diameter on the outer wall of one end of the non-wetting surface ring [3], or to set a protruding step

[13] or a retaining ring on the wall between the interfaces to prevent the non-wetting surface ring [3] or the densely filled non-wetting surface material from sliding arbitrarily.

[0032] Alternatively, a step

[13] and a fastening cap

[14] can be installed on the wall between the pipe interfaces, and a flexible non-wetting surface ring[3] can be installed between the fastening cap

[14] and the step

[13] . The fastening cap

[14] and the step

[13] will cause the non-wetting surface ring[3] to be squeezed from both ends to the middle and expand laterally.

[0033] The method of segmented connection of the pipeline is to set a pressure ring

[16] or material that can expand by absorbing water in a non-wetting surface ring [3] or sealing gasket

[11] with partial annular defects or annular water permeability, or to directly process a continuous non-wetting surface on part of the surface of the pressure ring

[16] that is easy to expand by absorbing water.

[0034] A space of fixed size is set between the pipe interface, or between the pressure plate

[15] of the pipe step or fastening cover

[14] and the floor slab [1] to place the pressure ring

[16] . The space of fixed size is the upper and lower fixed retaining rings [9] or steps set on the pipe or pipe interface [4], or a retaining ring set on the outer ring of the pressure plate

[15]

[17] , or a non-wetting surface pit set between the pipe interfaces, or an I-shaped ring fixing frame with a non-wetting surface on the inner surface of the interface.

[0035] The method of segmented pipe connection is to set a non-wetting surface sealing sleeve

[29] on the inlet side of the non-wetting surface ring [3] or sealing gasket

[11] that is integral with or can be tightly connected to the non-wetting surface ring [3] or sealing gasket

[11] and can be tightly fitted to the outer wall of the inner pipe or the inner cavity of the outer pipe; the sealing sleeve

[29] is elastic; the sealing sleeve

[29] is wedge-shaped in the whole, which can be tightly fitted to the pipe wall at the far end of the non-wetting surface ring [3] or sealing gasket

[11] ; an elastic or rigid fastening ring is added at the far end of the sealing sleeve so that the sealing sleeve

[29] can fit more tightly to the pipe wall; a leakage hole is set on the non-wetting surface ring [3] on the sealing side of the non-wetting surface ring [3] with the non-wetting surface ring [3] or the non-wetting surface ring [3] on the sealing side of the pipe wall is not tightly in contact with the pipe wall, so as to prevent the water flow that seeps into the sealing sleeve

[29] and the pipe wall from generating pressure.

[0036] The method of segmented connection of the pipeline is to extend the upper end of the pipeline or pipeline interface [4] directly out of the floor to a certain height to prevent water from flowing into the pipeline or pipeline interface [4], and to pass the sealed pipeline network

[18] through the pipeline or pipeline interface [4].

[0037] In addition, the pipe segment connection method provided by this invention also has the following beneficial effects:

[0038] 1. It has overcome the technical difficulties of existing pipe interfaces, enabling pipe connection engineering to evolve from the past strictly closed system to a direct assembly method, which greatly reduces the difficulty of engineering construction and production costs.

[0039] 2. This pipe connection method is simple and convenient to assemble and maintain, and does not require high technical skills from construction personnel.

[0040] 3. This pipe connection method completely solves the problem of connecting segmented pipes in buildings or reconnecting damaged pipes. Attached Figure Description

[0070] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0071] The embodiments of this invention are written in a progressive manner.

[0072] The non-wetting surface in this invention includes hydrophobic surfaces, hydrophilic surfaces without surface wetting, and neutral surfaces without surface wetting, but hydrophobic surfaces are preferred; the non-wetting material, component, or strip includes hydrophobic material, hydrophilic material without surface wetting, and neutral material without surface wetting, but hydrophobic material is preferred.

[0073] In this invention, hydrophilicity refers to a hydrophilic surface that has surface wetting, adsorption and siphoning effects; hydrophilic materials or hydrophilic strips, hydrophilic guiding strips or components, etc., are preferably hydrophilic materials that have surface wetting, adsorption and siphoning effects.

[0074] The pipe segment connection method provided by the present invention is to process the surface of the overlapping area of ​​the pipe interface with a continuous non-wetting surface to solve the current problem of difficult seepage prevention at pipe interfaces. In the overlapping area of ​​the pipe interface, a deformable non-wetting surface or material, preferably flexible, can also be set. In the non-wetting surface functional area, a water diversion facility can also be set to divert and discharge a small amount of water from the non-wetting surface waterproof functional area.

[0075] In this invention, the inlet side is the side where water may seep into the pipe interface, and the outlet side is the side where the water seeps out of the pipe interface.

[0076] Combination Figure 1 , Figure 2 A suitable-sized hole [2] is set at the pipe interface of the floor slab [1] with good waterproof performance, and at least a continuous annular non-wetting surface ring

[26] is processed on the annular surface of the hole [2]. It is preferable that the non-wetting surface ring is set at the upper part of the hole [2]. The non-wetting surface ring should be as flat as possible. Alternatively, more or all of the surfaces in the hole [2] can be processed into non-wetting surfaces. The outer surface of the pipe or pipe interface [4] at least where it overlaps with the non-wetting surface ring in the hole [2] is processed into a continuous non-wetting surface. Alternatively, more of the outer surfaces of the pipe or pipe interface [4] can be processed into non-wetting surfaces, such as Figure 2 As shown. Insert the pipe or pipe interface [4] into the hole [2], and tightly fit the non-wetting surface of the pipe or pipe interface [4] with the non-wetting surface ring in the hole [2]. The non-wetting surface of the pipe or pipe interface [4] tightly fitting with the hole [2] prevents water from the floor slab [1] from seeping into the interface between the pipe or pipe interface [4] and the floor slab [1]. When the pipe or pipe interface [4] is a standard pipe, its length should be greater than the thickness of the floor slab [1] to facilitate the connection between the upper and lower pipes and the pipe or pipe interface [4]. This connection method is also applicable to various pipes, especially sewer connections with low pipe pressure. When connecting, simply fit the non-wetting surfaces of the overlapping parts of each interface tightly. However, it is always advisable to use a pipe-to-sleeve connection. That is, use a standard pipe for the upper interface and a standard pipe-outer sleeve for the lower interface. Always insert the upper interface directly into the lower sleeve interface so that the water can flow smoothly into the lower pipe. The non-wetting surfaces of the pipe interface [4] tightly fit together prevent the water in the pipe from seeping into the pipe interface.

[0077] Furthermore, in combination Figure 3Non-wetting surface rings [3] can be set between the non-wetting surfaces of the overlapping parts of the pipe interface to make the non-wetting surfaces of the overlapping parts of the interface fit more tightly and improve the seepage prevention effect; the non-wetting surface rings [3] should be flexible, easily deformable and have suitable elasticity, and the non-wetting surface rings [3] can be cylindrical, annular or other suitable shapes.

[0078] Furthermore, in combination Figure 24 It involves setting a step

[13] larger than the diameter of the hole [2] or the outer sleeve on the outer wall of one end of the non-wetting surface ring [3]. The step

[13] prevents the non-wetting surface ring [3] from being pulled away from the installation position when installing pipes to pipes or pipe interfaces [4], thus improving the accuracy of installation. For aesthetic purposes, a recess of the same size as the step

[13] can also be set on the outer ring of the hole [2] in the floor slab [1]. Similarly, the step

[13] can also be set on the inner wall of the hole [2] or the outer sleeve.

[0079] Furthermore, in combination Figure 11 , Figure 25 A step is provided on one side of the pipe wall in the middle of the pipe or pipe joint [4]

[13] , and an external thread is provided on the other side of the pipe wall in the middle

[12] , such as Figure 11 As shown; settings are as follows Figure 25 The fastening cap

[14] with internal thread

[25] shown is used to install a flexible non-wetting surface ring [3] between the step

[13] and the external thread

[12] . The fastening cap

[14] is then used to press the flexible non-wetting surface ring [3] tightly between the fastening cap

[14] and the step

[13] , so that the flexible non-wetting surface ring [3] is squeezed and expanded from both ends to the middle, so that the non-wetting surface ring [3] can fit better with the inner and outer pipe walls and the hole wall, thereby improving the seepage prevention effect. At this time, the outer diameter of the step

[13] and the fastening cap

[14] should preferably not be greater than the diameter of the hole [2] or the interface outer sleeve, so that the step

[13] and the fastening cap

[14] can enter the hole [2] or the interface outer sleeve to compact the flexible non-wetting surface ring [3]. Similarly, the step

[13] and the thread

[12] can also be set on the inner wall of the hole [2] or the outer sleeve, and the fastening cap

[14] can be changed to an external thread

[25] .

[0080] Furthermore, in combination Figure 4At least the surface of the pipe or pipe interface below the outlet side of the pipe interface overlap is processed into a hydrophilic surface [5], or at least a layer of hydrophilic material is added to the pipe or pipe interface below the outlet side of the pipe interface overlap. All pipes or pipe interfaces below the outlet side of the pipe interface overlap can be added with hydrophilic material or processed into a hydrophilic surface; the lower surface of the hole [2] or the outer sleeve interface is processed into an annular non-wetting surface, the width of the annular non-wetting surface is not less than the width of the hydrophilic material on the pipe in contact with the lower surface of the outer sleeve interface, or more surfaces of the lower surface of the hole [2] or the outer sleeve interface can be processed into a non-wetting surface. When a small amount of water leaks at the pipe joint, the hydrophilic surface [5] or hydrophilic material on the pipe will adsorb the leaking water onto the pipe or the outer wall of the pipe joint below the joint, and the water will flow downward along the pipe or the outer wall of the pipe joint, preventing the leaking water from flowing into the hole [2] or the non-wetting surface of the outer surface of the outer joint, thus preventing the leaking water from corroding the lower surface of the floor slab [1].

[0081] Furthermore, in combination Figure 23 The hydrophilic surface [5] or the lower part of the hydrophilic material on the pipe below the interface can be set as a slope with a suitable gradient

[21] . At least the pipe wall at the edge of the slope

[21] should be processed with a continuous non-wetting surface, and a drainage band

[22] should be set at the lowest point of the slope

[21] . One end of the drainage band

[22] is connected to the lowest point of the slope

[21] , and the other end of the drainage band

[22] leaves the pipe wall and hangs down. A water flow collection and drainage system

[23] should be set at or below the hanging end of the drainage band

[22] . The leakage water flow on the pipe wall is guided by the drainage band

[22] to the end and drips into the water flow collection and drainage system

[23] . The leakage water flow is then discharged by the water flow collection and drainage system

[23] , thus completing the seepage prevention and drainage task.

[0082] Furthermore, the drainage strip

[22] that leaves the pipe wall is wrapped with a waterproof membrane to improve the seepage prevention and drainage effect.

[0083] Furthermore, one or more drainage strips

[22] with hydrophilic slopes

[21] can be set at intervals below the hydrophilic slopes

[21] and extend into the drainage system

[23] or the pipe to improve the seepage prevention and drainage effect. There must be a non-wetting surface or material separating the two hydrophilic slopes

[21] , or a waterproof membrane can be covered on the outside of the lower hydrophilic slope

[21] between the two hydrophilic slopes

[21] , and the upper edge of the waterproof membrane can be inserted between the lower edge of the upper hydrophilic slope

[21] and the pipe wall, so that the connection between the two hydrophilic slopes

[21] is separated by the waterproof membrane, but the upper edge of each hydrophilic slope

[21] can contact the pipe wall. In this way, one or more sets of hydrophilic slopes

[21] and waterproof membranes can be set alternately to improve the seepage prevention and drainage effect.

[0084] Furthermore, in combination Figure 5A flexible hydrophilic ring

[24] that can fully contact the inner and outer walls of the interface is provided below the non-wetting surface ring [3], or a flexible hydrophilic material is filled between the interfaces below the non-wetting surface ring [3]. The hydrophilic ring

[24] or the filled hydrophilic material adsorbs the leakage water flow on the hole [2] or the outer sleeve wall and guides it to the inner hydrophilic pipe wall or material, and then flows downward or is guided to the collection and drainage system

[23] . At this time, the lower edge of the hydrophilic ring

[24] or the hydrophilic material should preferably be an inclined surface of the hole [2] or the outer sleeve wall towards the inner pipe wall, which is conducive to the leakage water flow from the hole [2] or the outer sleeve wall to the inner pipe wall.

[0085] Furthermore, in combination Figure 6 Below the hydrophilic ring

[24] , a non-wetting surface ring [6] is provided that can make close contact with the inner and outer walls of the interface. Above the non-wetting surface ring [3], an integral raised non-wetting surface waterproof ring [7] is added. The waterproof ring [7] and the non-wetting surface ring [3] can also be separated and tightly set between the non-wetting surface ring [3] and the inner pipe wall. A hydrophilic drainage band [8] is set inside the waterproof ring [7] and the non-wetting surface ring [3]. The lower end of the drainage band [8] is connected to the hydrophilic ring

[24] , and the upper end extends a suitable distance beyond the upper edge of the waterproof ring [7]. The drainage band [8] absorbs the leakage water that seeps into the interface and leads it upward to the upper edge of the waterproof ring [7] before it evaporates freely. The upper edge of the waterproof ring [7] is higher than the upper surface of the floor slab [1] to prevent the water flow on the floor slab [1] from directly contacting the drainage band [8]. Alternatively, the drainage strip [8] at the upper edge of the waterproof ring [7] can be folded downwards but not in contact with the floor slab [1], so that the water flowing up can drip back onto the floor slab [1]. The waterproof ring [7] can also be replaced directly by an extended or heightened non-wetting surface ring [3].

[0086] Furthermore, in combination Figure 7 The hydrophilic drainage strip [8] is set into a ring shape to increase the expansion area of ​​the drainage strip [8], enhance the evaporation capacity of the drainage strip [8], and improve the drainage and seepage prevention effect.

[0087] Furthermore, in combination Figure 8A ring [9] is installed in the lower middle part between the pipe or pipe interface [4] and the hole [2] or the outer interface sleeve as a retaining ring. The ring [9] can also be connected to the wall of the pipe or pipe interface [4], or the hole [2] or the outer interface sleeve. The ring [9] should be able to fit tightly against the pipe wall of the pipe or pipe interface [4] and the hole [2] or the outer interface sleeve. The material should be a flexible non-wetting surface. Then, the non-wetting surface material is densely filled between the pipe or pipe interface [4] and the hole [2] or the outer interface sleeve above the ring [9]. The densely filled non-wetting surface material fits tightly against the non-wetting surface of the pipe wall or hole wall between the interface to prevent water leakage. A hydrophilic ring

[24] and a drainage band [8] can also be installed between the non-wetting surface material and the ring [9] and the inner pipe wall to improve the drainage and seepage prevention effect.

[0088] Furthermore, in combination Figure 9 , Figure 10 , Figure 11 , Figure 12 It involves machining a non-wetting circular annular surface

[10] on the outer surface (or lower surface) of the hole [2] of the floor slab [1]. The circular annular surface

[10] should preferably be flat, such as... Figure 9 As shown; mounted on a circular toroidal surface

[10] . Figure 10 The non-wetting surface sealing gasket

[11] shown is preferably made of a soft and easily deformable elastic material; a step

[13] not smaller than the hole [2] or the diameter of the interface sleeve is provided at one end of the pipe or pipe joint [4], and an external thread

[12] is provided on the pipe wall at the other end, such as Figure 11 As shown; settings are as follows Figure 12 The fastening cap

[14] with pressure plate

[15] and internal thread

[25] shown is a non-wetting surface, i.e., the pressing surface of pressure plate

[15] . During installation, the sealing gasket

[11] is attached to the circular annular surface

[10] of the floor slab [1]. The non-step end of the pipe or pipe interface [4] with step

[13] is passed through the hole [2] and sealing gasket

[11] from the other side, and the step

[13] is made to be close to the bottom of the floor slab [1]. Then, the fastening cap

[14] with pressure plate

[15] is tightened to the external thread

[12] on the pipe or pipe interface [4], so that the pressure plate

[15] , sealing gasket

[11] and circular annular surface

[10] are tightly attached together. The tightly attached pressure plate

[15] , sealing gasket

[11] and circular annular surface

[10] prevent water leakage. Alternatively, the step

[13] on the pipe or pipe joint [4] can be replaced with a pressure plate

[15] , thus eliminating the need for the pressure plate

[15] on the fastening cover

[14] . Then, the installation direction can be adjusted according to the actual situation. Similarly, other suitable methods can be used to replace the fastening method of the screw hole.

[0089] Furthermore, in combination Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 It is a pressure ring

[16] that expands upon absorbing water, placed in the non-wetting surface ring [3] or sealing gasket

[11] . When water leaks through the interface, the pressure ring

[16] expands after absorbing water, allowing the non-wetting surface ring [3] or sealing gasket

[11] to better fit with the non-wetting surface between the interfaces, thus better preventing water leakage. The pressure ring

[16] can be partially exposed while wrapped with a non-wetting membrane. The external part can be placed in the middle part of the inner and outer walls of the non-wetting surface ring [3], such as... Figure 13 As shown, it can also be set at the upper or lower end; it can also be set in the inner wall of the sealing gasket

[11] , such as Figure 14 As shown, or disposed in the outer wall of the sealing gasket

[11] , such as Figure 15 As shown, or disposed on the inner or outer ring of the upper or lower surface of the sealing gasket

[11] , such as Figure 16 As shown, or disposed on the middle ring of the upper and lower surfaces of the sealing gasket

[11] , such as Figure 17 As shown.

[0090] Furthermore, the booster ring

[16] can be made by wrapping water-absorbing and easily swellable powder or particulate matter (such as sodium polyacrylate, sodium methylsilicate, water-absorbing resin, etc.) with hydrophilic fabric or water-permeable membrane to form a ring-shaped booster ring

[16] . Then, the main body of the booster ring

[16] is wrapped with a non-wetting membrane (preferably soft and stretchable) while exposing a small part of the booster ring

[16] to the outside, so that the main surface of the booster ring

[16] is as non-wetting as possible. The exposed part should be able to contact the non-wetting surfaces on both sides of the interface. The position of the booster ring

[16] exposed can be freely selected, but the middle part of the booster ring

[16] or the outlet side is preferred. The pressure ring

[16] can also be made by wrapping water-absorbing and easily swellable powder or particulate material with a non-wetting membrane with water-permeable pores or micropores in the area that needs to be permeable; or the hydrophilic fabric or part of the water-permeable membrane of the pressure ring

[16] can be directly processed into a non-wetting surface that is impermeable; or the water-absorbing and easily swellable material can be directly processed into strips with a stable shape and appropriate size to replace the pressure ring

[16] , and then wrapped with a non-wetting membrane of appropriate size or specification; or a part of the surface of the pressure ring

[16] made of water-absorbing and easily swellable material can be directly processed into a non-wetting surface to save the non-wetting membrane.

[0091] Furthermore, in combination Figure 18 , Figure 19 In order to maintain a high pressure after water absorption, the pressure ring

[16] can be placed in a space of fixed size. It can be installed on the pipe wall of the pipe or pipe interface [4] in the hole [2] or the outer interface sleeve. Figure 18The two fixed retaining rings [9] shown above are used to install a non-wetting surface ring [3] with a pressure-boosting ring

[16] between the two fixed retaining rings [9], so that the non-wetting surface ring [3] can only expand between the interface between the two fixed retaining rings [9], resulting in a better pressure boosting effect. Similarly, a similar design can also be provided on the outer ring of the pressure plate

[15] . Figure 19 The retaining ring

[17] shown is used to install the sealing gasket

[11] with the pressure boosting ring

[16] inside the retaining ring

[17] , so that the sealing gasket

[11] can only expand between the interfaces inside the retaining ring

[17] , resulting in a better pressure boosting effect. Similarly, a non-wetting surface recess of appropriate size with an outward opening can also be provided on the inner wall of the hole [2] or the outer interface sleeve (the recess can be a regular geometric shape or a shape that is easy to install and process). The recess

[14] can be set in one or both of the two non-wetting surfaces between the interfaces. The pressure boosting ring

[16] is installed in the recess, so that the pressure boosting ring

[16] can only expand in the space formed by the recess after absorbing water, resulting in faster and higher pressure boosting.

[0092] Furthermore, an I-shaped ring-shaped fixing frame with good mechanical properties can be processed. The inner surface of the I-shaped fixing frame is preferably a non-wetting surface. Pressure rings

[16] are tightly installed on both sides of the fixing frame. The fixing frame with pressure rings

[16] installed on both sides is tightly installed between the two non-wetting surfaces at the interface. This allows the pressure rings

[16] to expand only in the limited or restricted space formed between the fixing frame and the non-wetting surface after absorbing water, resulting in faster and higher pressure increase and better waterproofing effect.

[0093] Furthermore, in combination Figure 20 By setting the upper end of the pipe or pipe interface [4] higher than the upper surface of the floor slab [1] and extending it directly to a certain or appropriate height above the upper surface of the floor slab, water flow on the floor slab [1] can be effectively prevented from entering the pipe or pipe interface [4], and the pipe or pipe interface [4] completes the anti-seepage task; then, an effective sealed pipe network

[18] with a smaller diameter is passed through the pipe or pipe interface [4], making the installation and connection of the pipe network

[18] more convenient. The pipe network

[18] and the pipe or pipe interface [4] can be fixedly connected, or a material can be filled between the pipe network

[18] and the pipe or pipe interface [4] for sealing.

[0094] Furthermore, in combination Figure 21 , Figure 22It is an extended outer sleeve interface

[19] where the length of the outer sleeve interface at the processing interface is significantly longer than the normal length

[20] , or an extended outer sleeve interface

[19] is directly set on the standard pipe. An extended inner insertion interface

[28] where the length of the standard pipe or inner insertion pipe at the processing interface is significantly longer than the normal length

[27] , and the length of the outer sleeve of the extended inner insertion interface

[28] is the normal standard length. The extended outer sleeve interface

[19] and the extended inner insertion interface

[27] are used together. The extended outer tube

[20] and the extended inner tube

[27] are combined to form an anti-slip extended stretching interface that does not slip off after stretching the joint distance or length of the standard or normal interface at the interface; during installation and connection, first insert the extended inner tube

[27] of the extended inner tube interface

[28] completely into the extended outer tube

[20] of the extended outer tube interface

[19] , and then connect the outer tube of the extended inner tube interface

[28] (or the inner tube of the extended outer tube interface

[19] ) to the front pipe. After aligning the ports (or interfaces), move the extended inner connector

[28] (or extended outer connector

[19] ) forward or outward, and tightly fit the standard outer connector of the extended inner connector

[28] onto the pipe in front (or insert the standard inner connector of the extended outer connector

[19] into the standard interface or standard outer connector of the pipe in front), so that the inner connector portion of the extended inner connector

[28] moves outward in the extended outer connector of the extended outer connector

[19] , but cannot... After all the pipes are pulled out, a limiting device of just the right length is set at the corresponding displacement between the extended inner insertion interface

[28] and the extended outer sleeve interface

[19] after the extended inner insertion interface

[28] is pulled out, and the interface movement is fixed to prevent the extended inner insertion interface

[28] and the extended outer sleeve interface

[19] from moving back to each other. The limiting device can be a circular retaining ring, which can be an open ring, or the pipe wall can be longitudinally broken with a standard pipe and then wrapped around the displacement point, or a flexible plate can be used to wrap around and stretch the displacement point. It makes full use of the length difference between the extended outer sleeve and inner insertion pipe combination and the standard outer sleeve and inner insertion pipe combination, which prevents the interface from slipping but is also convenient to connect. This method is suitable for the segmented connection of pipes between different floors, and is especially suitable for the replacement and maintenance of some pipes, making the connection of pipes more convenient and flexible.

[0095] Furthermore, in combination Figure 26It is a sealing sleeve

[29] integral with the non-wetting surface ring [3] or sealing gasket

[11] on the inlet side of the non-wetting surface ring [3] or sealing gasket

[11] , forming a sleeved non-wetting surface ring [3]. The sealing sleeve

[29] is preferably made of a flexible non-wetting surface material, and the circumference of the inner cavity of the sleeve is preferably not greater than the circumference of the outer wall of the inner pipe, so that the inner wall of the sealing sleeve

[29] can be tightly attached to the outer wall of the pipe. When the water in the pipe enters the gap of the pipe interface, the water pressure makes the sealing sleeve

[29] tightly wrap around the outer wall of the inner pipe, increasing the sealing distance or area and improving the sealing effect. In this embodiment, the non-wetting surface ring [3] and the sealing sleeve

[29] can also be set as separate parts. During installation, the sealing sleeve

[29] is first placed on the inner wall of the outer pipe of the pipe interface, and then the outer end of the sealing sleeve

[29] is pressed against the inner wall of the outer pipe by the non-wetting surface ring [3]. After the non-wetting surface ring [3] is inserted into the inner pipe, the sealing sleeve

[29] is pressed tightly against the inner wall of the pipe interface. At this time, the separate sealing sleeve

[29] and the non-wetting surface ring [3] can produce the same effect as the whole sleeved non-wetting surface ring [3]. In this embodiment, the sealing sleeve

[29] is preferably wedge-shaped as a whole, that is, the end closer to the non-wetting surface ring [3] is large and the end farther away from the non-wetting surface ring [3] is small, so that the sealing sleeve

[29] can better wrap tightly around the outer wall of the pipe. An elastic tightening ring can also be added to the outer periphery of the far end of the sealing sleeve, so that the sealing sleeve

[29] can fit more tightly against the outer wall of the pipe. In this embodiment, the inner wall of the sealing sleeve

[29] and the outer wall of the inner pipe can be processed with a continuous hydrophobic surface, making it more difficult for water to leak from the inner wall of the sealing sleeve

[29] and the outer wall of the pipe, thereby improving the sealing effect. Similarly, the sealing sleeve

[29] can be processed to have a circumference not less than the circumference of the inner cavity of the outer pipe, so that the outer wall of the sealing sleeve

[29] can fit tightly against the inner wall of the outer pipe. In this case, the sealing sleeve

[29] should preferably be in the shape of an inverted wedge, that is, the end closer to the non-wetting surface ring [3] is small and the end farther away from the non-wetting surface ring [3] is large, so that the sealing sleeve

[29] can fit tightly against the inner wall of the outer pipe better. An elastic expansion ring can also be added to the inner circumference of the far end of the sealing sleeve, so that the sealing sleeve

[29] can fit more tightly against the inner wall of the outer pipe. The hardness of the far end of the sealing sleeve

[29] can also be increased, or a rigid hard ring of appropriate size can be set in the flexible sealing sleeve, so that the sealing sleeve

[29] can fit tightly against the inner wall of the outer pipe better. Sealing sleeves

[29] can also be set on both the inner and outer sides of the non-wetting surface ring [3] so that both the inner and outer walls of the pipe interface have sealing sleeves

[29] , thereby improving the anti-seepage performance.

[0096] Furthermore, leakage holes can be provided on the sealing sleeve

[29] with a non-wetting surface ring [3] on the sealing side of the pipe wall to relieve pressure, or the non-wetting surface ring [3] on the sealing side of the pipe wall can be made not to be in close contact with the pipe wall in order to relieve pressure, so that the water flow that seeps into the sealing sleeve

[29] and the pipe wall cannot generate pressure, so that the sealing sleeve

[29] can be tightly attached to the pipe wall and improve the sealing effect.

[0097] Furthermore, a thickened flexible non-wetting surface ring [3] can be combined with a rigid gasket to replace the sleeved flexible non-wetting surface ring [3]. The flexible non-wetting surface ring [3] should be easily deformable under pressure and its size should be able to make close contact with the inner and outer walls of the water pipe interface. The rigid gasket is installed in the retaining ring or step inside the interface. When it is difficult to install the rigid gasket as a whole in the retaining ring or step, two half-circles of rigid gaskets can be spliced ​​together and installed in the retaining ring or step. After installation, when the water pressure in the water pipe is large, the water pressure first squeezes the flexible non-wetting surface ring [3] and has a pushing effect on the interface. However, it cannot move outward under the joint obstruction of the rigid gasket and the retaining ring or step. Since the fluid pressure between the outer side of the interface and the inner and outer rings of the flexible non-wetting surface ring [3] and the inner and outer walls of the water pipe interface is almost zero, the flexible non-wetting surface ring [3] undergoes lateral deformation under the action of fluid pressure and makes the inner and outer rings contact and fit more tightly with the inner and outer walls of the water pipe interface. The rigid gasket should have a small gap with the retaining ring, step, or pipe wall at the interface, but the flexible non-wetting surface ring [3] should not be damaged under fluid pressure, so that the fluid pressure between the inner and outer rings of the flexible non-wetting surface ring [3] and the inner and outer walls of the water pipe interface can always be kept at the lowest range. When the gap between the retaining ring or step and the other pipe wall at the interface is small and can act as a rigid gasket, the rigid gasket can be omitted.

[0098] Furthermore, in combination Figure 28 It involves installing a sleeve

[32] in an existing vertically installed pipe interface. The upper end of the sleeve

[32] is tightly fitted or sealed to the interface step above the existing pipe interface to prevent water leakage between the sleeve

[32] and the existing pipe interface. To improve the sealing performance between the upper end of the sleeve

[32] and the upper interface step of the existing pipe interface, an annular ring that fits to the upper interface step of the existing pipe interface can be installed at the upper end of the sleeve

[32] . The lower end of the sleeve

[32] can extend into the pipe

[18] inside the lower interface, allowing water to directly enter the pipe

[18] inside the lower interface, thus improving the bonding between the surface energy interface and the existing interface. The sleeve

[32] can also be replaced by a flexible tubular membrane, and it is advisable to install an annular ring at the upper end that can fit tightly or seal to the interface step above the existing pipe interface. The surface of the sleeve

[32] , especially the surface at the upper interface, should preferably be a non-wetting surface.

[0099] Furthermore, in combination Figure 27It is to set one or more openings

[31] along the pipe wall longitudinally at the end of the outer layer interface [4] of the pipe, so that the end of the outer layer interface [4] of the pipe opens naturally. At the inner wall port of the outer layer interface [4] of the pipe, one or more annular protrusions

[30] are processed or fixed. At the outer wall port of the inner layer interface [4] of the pipe, an indented annular concave ring, retaining ring or step corresponding to and matching the annular protrusions

[30] is processed or fixed. During installation, the annular protrusions

[30] and the concave ring are engaged together. Then, fasteners or devices (such as tie wire, fixing ring, locking ring, etc.) are used on the outer wall of the end of the outer layer interface [4] of the pipe to lock the end of the pipe (that is, to close the opening

[31] as much as possible) as the pipe interface locking mechanism to prevent the inner layer pipe from easily slipping out of the outer layer interface [4] of the pipe and improve the pressure bearing capacity of the interface. Similarly, annular protrusions

[30] can be machined or fixed on the outer wall of the inner pipe, and annular concave rings, retaining rings or steps can be machined or fixed at the inner wall port of the outer pipe interface [4].

[0100] Furthermore, it sets recessed annular fastening recesses on the inner and outer walls at the corresponding positions of the pipe interface, and then sets an annular fastening ring that matches the fastening recesses in the fastening recesses. The fastening recesses and the annular fastening rings prevent the inner pipe from easily slipping out of the outer pipe interface [4].

[0101] Furthermore, it involves using two whole or open annular rigid fastening rings to sandwich a flexible ring to form a combined flexible fastening ring; or using two semi-annular rigid fastening rings to sandwich a half-annular flexible ring to form a semi-annular combined flexible fastening ring, or using two sets of semi-annular flexible fastening rings to form a combined flexible fastening ring; or using two sets of two semi-annular rigid fastening rings to sandwich an annular flexible ring to form a combined flexible fastening ring, so that the combined fastening ring has both rigidity and flexibility, and the rigid fastening rings on both sides of the flexible ring can also be used in combination, either whole, open, or semi-annular.

[0102] Furthermore, interlocking annular wedge-shaped openings or annular patterns can be directly machined laterally on the inner and outer walls of the interface locking point. After the interface is locked, the interlocking of the annular wedge-shaped openings or annular patterns directly prevents the interface from slipping. Similarly, the inner and outer walls of the interface locking point can be machined into rough surfaces to increase the longitudinal sliding friction coefficient and prevent the locked interface from slipping. The rough surface can be an uneven rough surface, or the pipe wall at the interface can have interlocking anti-slip or anti-detachment barbs.

[0103] Furthermore, annular anti-slip pads can be added between the inner and outer walls of the locking joint with annular wedge-shaped openings or annular patterns, or between rough surfaces with a high coefficient of friction. Alternatively, rigid cylindrical annular anti-slip washers with sharp protrusions and longitudinal openings can be added directly to the surface of a normal pipe joint or to surfaces treated with anti-slip measures (such as annular wedge-shaped openings, annular patterns, rough surfaces, etc.) to further improve the anti-slip and locking effects. Annular anti-slip pads and rigid cylindrical annular anti-slip washers can also be made by rolling appropriately sized anti-slip sheets or rigid anti-slip pads around the water pipe.

[0104] Furthermore, in this embodiment, protruding fixed rings, steps, or ridges that can block or lock each other can be fixedly connected or provided on the inner and outer walls of the pipe interface, and the locking mechanism is formed by the mutual locking of the fixed rings, steps, or ridges.

[0105] Furthermore, in this embodiment, a flexible ring or gasket can be provided between the locking mechanisms of the pipe interface to provide a certain buffer space between the locking mechanisms. The flexible ring or gasket should preferably be elastic to improve the shock resistance and tensile strength of the interface.

[0106] Furthermore, in this embodiment, an external thread can be provided at the pipe interface, and an anti-slip washer can be provided between the interfaces. The interface can be locked with a locking nut that engages with the external thread. The anti-slip washer is preferably wedge-shaped with a thinner inner side and a thicker outer side, and the locking nut is preferably equipped with a retaining ring that can prevent the anti-slip washer from moving outward.

[0107] Furthermore, a rigid ring with numerous barbs or sharp wedge-shaped rings on its inner wall can be installed inside the water pipe interface. This rigid ring can move in and out within the water pipe interface, perfectly fitting the inner wall of the water pipe. The barbs or sharp wedge-shaped rings face the inner end of the water pipe interface, preventing the water pipe from being pulled out after insertion. During installation, first insert the water pipe into the rigid ring inside the water pipe interface, then forcefully pull the water pipe outward to cause lateral deformation of the sealing ring, ensuring tight contact with both the inner and outer walls of the water pipe interface. Finally, a locking or fastening mechanism is used to fix or lock the inner wall or port of the sealing ring to the outer wall of the water pipe, further improving the sealing performance of the water pipe interface. The sealing ring can be fixed or locked by machining or fastening screw holes on the water pipe or water pipe interface and then tightening it with screws; alternatively, a rigid ring with numerous barbs or sharp wedge-shaped rings on its inner wall can be placed opposite the rigid ring in the water pipe interface on the outer water pipe, ensuring a tight contact between the outer rigid ring and the port of the water pipe interface. For ease of installation, an opening can be provided in the rigid ring to allow it to fit into the water pipe, and finally, a suitable fastener can be used to tighten it on the open rigid ring; other suitable fastening methods can also be used to fasten the outer wall of the water pipe to the water pipe interface outside the sealing ring. Additionally, a flexible or elastic washer can be placed between the fastener on the outer wall of the water pipe and the port of the water pipe interface. The flexible washer should ideally be elastic; the tightening effect can be judged by observing the deformation of the flexible washer at the port of the water pipe interface during tightening. This provides a buffer space between the locking mechanisms, and the flexible ring or washer should ideally be elastic to improve the shock resistance and tensile strength of the interface.

[0108] In this invention, the inlet side is the side where water may seep into the pipe interface, and the outlet side is the side where the water seeps out of the pipe interface.

[0109] In this implementation scheme, when the pipe, especially the inner pipe, is not rigid and is prone to deformation, a rigid hard ring that fits tightly against the inner pipe wall can be installed in the inner pipe to improve the stability of the interface.

[0110] Furthermore, each hydrophilic drainage component, non-wetting strip, non-wetting gasket or washer in this implementation scheme can be processed individually or combined with corresponding accessories and attachments, non-wetting sheets, fasteners to form a combined accessory; adjacent structures or components can also be processed together to form a combined accessory, which facilitates construction and installation.

[0111] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
