Description

Technical Field

[0001] The present invention relates to the technical field of pipeline construction, and in particular to a waterproof structure for a through-wall pipeline and a construction method thereof. Background Art

[0002] Urban utility corridors integrate various engineering pipelines, including power, communications, gas, heating, and water supply and drainage. Heat pipes and gas pipelines, among others, must pass through the walls between the corridors to pass from one corridor to another. Because walls contain moisture, the joints between the pipes and the walls must be sealed and waterproofed to ensure the safe operation of urban utility corridors. Conventional technology typically involves installing waterproof casings between the pipes and the walls to waterproof the gaps.

[0003] When the waterproof sleeve in the prior art is used, the pipe is simply passed through the inside of the waterproof sleeve so that the outer wall of the pipe contacts the inner wall of the waterproof sleeve. For example, when high-temperature liquid is transported inside the pipe, the pipe will transport heat to the waterproof sleeve, causing the temperature of the waterproof sleeve to rise. When low-temperature liquid is transported in the pipe, the temperature of the waterproof sleeve will also drop. The long-term thermal expansion and contraction of the waterproof sleeve will cause the length of the waterproof sleeve to change, thereby affecting the waterproof performance of the waterproof sleeve, and the pipe cannot be effectively waterproofed subsequently. Summary of the Invention

[0004] In view of the defects in the prior art, the present invention provides a waterproof structure for wall-penetrating pipes and a construction method thereof.

[0005] A waterproof structure for through-wall pipes comprises a wall and a waterproof sleeve, wherein a mounting hole is opened inside the wall, the waterproof sleeve is connected to the wall via a provided mounting mechanism, a pipe body is inserted into the waterproof sleeve, two movable sleeves are slidably installed inside the waterproof sleeve, an auxiliary supporting mechanism for limiting support of the pipe body is installed at the ends of the two movable sleeves that are away from each other, and a protective mechanism for protecting the interior of the waterproof sleeve is installed at the ends of the two movable sleeves that are close to each other.

[0006] Optionally, the installation mechanism includes two fixing blocks, which are installed at one end of the waterproof sleeve, and one side outer wall of the wall is provided with grooves adapted to the two fixing blocks.

[0009] Optionally, two fixing rods are installed at both ends of the waterproof sleeve, and a sliding groove is provided on the outer wall of the side where the two fixing rods are close to the inner wall of the waterproof sleeve. Two sliders that can slide back and forth in the sliding groove are installed on the outer walls of the two movable sleeves.

[0010] Optionally, the protection mechanism includes an airbag installed at one end of the two movable sleeves, a plurality of one-way valves are installed on the side of the two airbags, and a cavity connected to the airbag is opened inside the two movable sleeves.

[0011] Optionally, pistons are slidably installed inside the two cavities, semicircular movable plates are installed at the ends of the two pistons that are away from each other, connecting plates are rotatably installed at the ends of the two movable plates that are away from each other, connecting blocks are installed on the outer walls of the two movable sleeves, and the two connecting plates are threadedly connected to the connecting blocks through second bolts.

[0012] Optionally, the support mechanism includes a screw, the screw thread is installed on the end of the movable plate away from the movable sleeve, the top end of the screw is installed with an arc-shaped support plate, and the bottom end of the screw is installed with a rotating part.

[0013] Optionally, the top of the arc-shaped support plate is adapted to the outer wall of the pipe body, a wavy protrusion is provided on the top of the arc-shaped support plate, and two scrapers are installed on the outer wall of the arc-shaped support plate away from the movable plate.

[0014] A construction method for a wall-penetrating pipe waterproof structure, the use method includes the above-mentioned waterproof structure, and the construction method further includes the following steps:

[0015] Step 1: Rotate the two rotating blocks toward each other, then pass the end of the waterproof casing with the rotating block through the mounting hole so that the two fixed blocks can smoothly enter the interior of the groove. Finally, rotate the two rotating blocks back to their original position and then thread them to the wall with the first bolt.

[0016] Step 2: In order to improve the stability of the connection between the waterproof sleeve and the mounting hole and the waterproof performance of the waterproof sleeve to the pipeline body, after the waterproof sleeve is installed, a hose filled with adhesive or waterproof coating is inserted into the guide groove, and the adhesive or waterproof coating inside the hose is transported into the guide groove by an external conveying mechanism, and flows into the interior of the multiple arc grooves. After the adhesive or waterproof coating is dried and solidified, an obstacle is formed between the inner wall of the mounting hole and the waterproof sleeve, and the connection between the waterproof sleeve and the mounting hole is more stable.

[0017] Step 3: After the waterproof sleeve is installed, the linear motors inside the two slides are controlled to start, driving the two sliders inside the two slides to move away from each other, driving the two movable sleeves to slide out from the inside of the waterproof sleeve, making it easier for the staff to clean the debris on the inner wall of the movable sleeve, thereby facilitating the subsequent use of the movable sleeve and the pipeline body;

[0018] Step 4: After the debris inside the movable casing is cleaned, the pipe body needs to be laid through the interior of the movable casing, and one of the movable plates is controlled to rotate with the movable casing as the center, driving the arc support plate and other components to rotate upward, so that the arc support plates at the left and right ends are in an up and down dislocation state. At this time, when one end of the pipe body is transported from the left end to the right end of the waterproof casing, the two arc support plates can respectively abut against the outer wall of the pipe body from the upper and lower ends, so that the pipe body is in the center position when passing through the interior of the waterproof casing, ensuring that the distance between the pipe body and the inner wall of the movable casing is the same, avoiding the pipe body being too close to the movable casing during use, which is easy to bring adverse effects to the movable casing.

[0019] The beneficial effects of the present invention are embodied in:

[0020] 1. In this invention, the auxiliary support mechanism is provided, so that the pipe body can always be in the center position during the process of passing through the waterproof casing, ensuring that the distance between the pipe body and the inner wall of the movable casing is the same, avoiding the pipe body being too close to the movable casing during use, which may easily bring adverse effects to the movable casing, and can also improve the aesthetics between the pipe body and the waterproof casing, indirectly improving the applicability of the waterproof casing; after the pipe body passes through the interior of the two movable casings, the two arc-shaped support plates remain in an upper and lower staggered state, so that the two arc-shaped support plates clamp and fix the pipe body, avoiding the pipe body being easily affected by the settlement of the wall itself or other factors during use, resulting in the problem of poor working stability of the pipe body.

[0021] 2. In this invention, the protective mechanism is set up to seal the gap in the movable sleeve, preventing animals such as mice from moving back and forth indoors through the gap inside the movable sleeve; and when the pipe body passes through the interior of the waterproof sleeve, the air bags inside the two movable sleeves are in an inflated state. When the pipe body passes through the circular hole inside the air bag, the dust and other debris on the surface of the pipe body can be automatically cleaned off, making it convenient for subsequent staff to identify the markings sprayed on the surface of the pipe body, and avoiding the problem that after the pipe body is installed, the sprayed markings are blocked by dust and other debris on the surface, affecting the staff's ability to identify the function of the pipe body.

[0022] 3. In this invention, when the pipe body and the waterproof sleeve are in normal use, after small animals such as mice enter the interior of the movable sleeve, the movable sleeve is driven to move back and forth repeatedly inside the waterproof sleeve by the slider to drive the mice inside the movable sleeve. In the process of the mobile sleeve moving back and forth, the arc-shaped support plate is driven to move back and forth together, so that friction and noise are generated between the raised portion on the top of the arc-shaped support plate and the pipe body, further improving the efficiency of driving away mice and preventing mice from having an adverse effect on the use of the pipe body.

[0023] 4. In the present invention, if welding maintenance is required for the position of the pipe body near the waterproof casing, in order to avoid the sparks generated by the welding of the pipe body from continuously falling downward, which may easily cause a safety hazard, during the welding of the pipe body, the slider can be moved in the slide groove to drive the movable casing to the end of the waterproof casing, and the movable plate can be pulled out of the cavity, so that the movable plate located below the welding part of the pipe body can block the sparks falling from the welding pipe body, thereby reducing the chance of sparks falling to the surface of flammable materials below and causing fire.

DETAILED DESCRIPTION

[0033] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0034] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0035] Reference Figure 1-Figure 7 A wall-penetrating pipe waterproof structure includes a wall 1 and a waterproof sleeve 3. A mounting hole 9 is opened inside the wall 1. The waterproof sleeve 3 is connected to the wall 1 through a set mounting mechanism. The pipe body 2 is inserted into the waterproof sleeve 3. Two movable sleeves 15 are slidably installed inside the waterproof sleeve 3. The ends of the two movable sleeves 15 that are away from each other are each installed with an auxiliary supporting mechanism for limiting the support of the pipe body 2. The ends of the two movable sleeves 15 that are close to each other are each installed with a protective mechanism for protecting the inside of the waterproof sleeve 3.

[0036] As a technical optimization solution of the present invention, the installation mechanism includes two fixing blocks 7, which are installed at one end of the waterproof sleeve 3, and a groove 10 adapted to the two fixing blocks 7 is opened on the outer wall of one side of the wall 1.

[0037] As a technical optimization solution of the present invention, two rotating blocks 5 are rotatably mounted on the other end of the waterproof sleeve 3. Both rotating blocks 5 are threadedly connected to the outer wall of the other side of the wall 1 via a first bolt 6. When installing the waterproof sleeve 3 in a pre-opened mounting hole 9 inside the wall 1, the two rotating blocks 5 can be rotated toward each other. After the end of the waterproof sleeve 3 with the rotating blocks 5 is passed through the mounting hole 9, the two fixing blocks 7 can be smoothly inserted into the interior of the groove 10. Finally, the two rotating blocks 5 are rotated back to their original position and connected to the wall 1 via the first bolt 6.

[0038] As a technical optimization solution of the present invention, the outer wall of the waterproof sleeve 3 is provided with a plurality of guide grooves 8, and the outer wall of the waterproof sleeve 3 is also provided with a plurality of arc grooves 11 connected to the guide grooves 8. After the waterproof sleeve 3 is installed inside the mounting hole 9, in order to improve the stability and tightness of the connection between the waterproof sleeve 3 and the mounting hole 9 and improve the waterproof effect of the waterproof sleeve 3, a hose containing an adhesive or waterproof coating can be inserted into the guide groove 8, and the adhesive or waterproof coating inside the hose is transported into the guide groove 8 by an external conveying mechanism, and flows into the interior of the plurality of arc grooves 11, so as to facilitate the adhesive or waterproof coating to fill the gap between the mounting hole 9 and the waterproof sleeve 3.

[0039] As a technical optimization solution of the present invention, two fixed rods 4 are installed at both ends of the waterproof sleeve 3. The outer wall of the two fixed rods 4 on the side close to each other and the inner wall of the waterproof sleeve 3 jointly define a slide groove 12. The outer walls of the two movable sleeves 15 are each equipped with two sliders 13 that can slide back and forth within the slide grooves 12. Linear motors are pre-installed inside each slide groove 12. When activated, the linear motors can drive the two sliders 13 to move back and forth within the slide grooves 12, thereby driving the movable sleeves 15 to move back and forth synchronously within the waterproof sleeve 3.

[0040] As a technical optimization solution of the present invention, the protective mechanism includes airbags 25 installed at the adjacent ends of the two movable sleeves 15. Multiple one-way valves 24 are installed on the adjacent side of each airbag 25. Each movable sleeve 15 has a cavity 18 inside that communicates with the airbags 25. A wear-resistant layer is bonded to the outer walls of each airbag 25 to enhance its strength and service life.

[0041] As a technical optimization solution of the present invention, pistons 26 are slidably mounted inside the two cavities 18. A semicircular movable plate 16 is mounted on the distal ends of the two pistons 26. A connecting plate 17 is rotatably mounted on the distal ends of the two movable plates 16. A connecting block 14 is mounted on the outer walls of the two movable sleeves 15. Both connecting plates 17 are threadedly connected to the connecting block 14 via second bolts 19. Pushing the movable plate 16 within the cavity 18 can drive the piston 26 to move within the cavity 18, thereby injecting the air within the cavity 18 into the airbag 25, causing the airbag 25 to expand within the movable sleeve 15 and tightly abut the outer wall of the pipe body 2, thereby blocking the gap within the movable sleeve 15 and preventing animals such as mice from moving back and forth indoors through the gap within the movable sleeve 15.

[0042] As a technical optimization solution of the present invention, the support mechanism includes a screw 23, which is threadedly mounted on the end of the movable plate 16 away from the movable sleeve 15. The top end of the screw 23 is mounted with an arc-shaped support plate 20, and the bottom end of the screw 23 is mounted with a rotating portion. The screw 23 is rotated by rotating the rotating portion, and the arc-shaped support plate 20 is driven to move toward the pipe body 2 until the top end of the arc-shaped support plate 20 is tightly abutted against the outer wall of the pipe body 2. This allows the arc-shaped support plate 20 to support the pipe body 2 inside the waterproof sleeve 3, preventing the outer wall of the pipe body 2 from abutting against the inner wall of the movable sleeve 15, which would cause the pipe body 2 to affect the movable sleeve 15 itself during use.

[0043] As a technical optimization solution of the present invention, the top of the arc-shaped support plate 20 is adapted to the outer wall of the pipe body 2. A wavy protrusion 22 is provided on the top of the arc-shaped support plate 20. Two scrapers 21 are installed on the outer wall of the arc-shaped support plate 20 away from the movable plate 16. After the second bolts 19 between the two connecting plates 17 and the connecting block 14 on the outer wall of the movable plate 16 are removed, the movable plate 16 can move back and forth and rotate within the cavity 18. During the process of manually rotating the movable plate 16, the outer wall of the arc-shaped support plate 20 with the protrusion 22 rubs against the outer wall of the pipe body 2, thereby cleaning impurities such as welding slag on the outer wall of the pipe body 2, preventing corrosion of the pipe body 2 by impurities such as welding slag and extending the service life of the pipe body 2.

[0044] A construction method for a wall-penetrating pipe waterproof structure, the use method includes the above-mentioned waterproof structure, and the construction method further includes the following steps:

[0045] Step 1: Rotate the two rotating blocks 5 toward each other, then pass the end of the waterproof sleeve 3 with the rotating block 5 through the mounting hole 9, so that the two fixing blocks 7 can smoothly enter the interior of the groove 10, and finally rotate the two rotating blocks 5 back to their original position, and then screw them to the wall 1 through the first bolt 6;

[0046] Step 2: In order to improve the stability of the connection between the waterproof sleeve 3 and the mounting hole 9 and the waterproof performance of the waterproof sleeve 3 on the pipe body 2, after the waterproof sleeve 3 is installed, a hose filled with adhesive or waterproof coating is inserted into the guide groove 8. The adhesive or waterproof coating inside the hose is transported into the guide groove 8 by an external transport mechanism and flows into the interior of the multiple arc grooves 11. After the adhesive or waterproof coating is dried and solidified, an obstacle is formed between the inner wall of the mounting hole 9 and the waterproof sleeve 3, and the connection between the waterproof sleeve 3 and the mounting hole 9 is more stable.

[0047] Step 3: After the waterproof sleeve 3 is installed, the linear motors inside the two slide grooves 12 are controlled to start, driving the two sliders 13 inside the two slide grooves 12 to move away from each other, driving the two movable sleeves 15 to slide out from the inside of the waterproof sleeve 3, making it convenient for the staff to clean the debris on the inner wall of the movable sleeve 15, thereby facilitating the subsequent use of the movable sleeve 15 and the pipe body 2;

[0048] Step 4: After the debris inside the movable sleeve 15 is cleaned, the pipe body 2 needs to be laid through the inside of the movable sleeve 15, and one of the movable plates 16 is controlled to rotate with the movable sleeve 15 as the center, driving the arc-shaped support plate 20 and other components to rotate upward, so that the arc-shaped support plates 20 at the left and right ends are in an up and down staggered state. At this time, in the process of transporting one end of the pipe body 2 from the left end to the right end of the waterproof sleeve 3, the two arc-shaped support plates 20 can respectively abut the outer wall of the pipe body 2 from the upper and lower ends, so that the pipe body 2 is in a centered position when passing through the interior of the waterproof sleeve 3, ensuring that the distance between the pipe body 2 and the inner wall of the movable sleeve 15 is the same, avoiding the pipe body 2 being too close to the movable sleeve 15 during use, which is easy to have an adverse effect on the movable sleeve 15.

[0049] In the present invention, when the user uses the device, a mounting hole 9 is pre-opened inside the wall 1, and then the two rotating blocks 5 are rotated in the direction of approaching each other, and the end of the waterproof sleeve 3 with the rotating block 5 is passed through the mounting hole 9, so that the two fixed blocks 7 can enter the interior of the groove 10. Finally, after the two rotating blocks 5 are rotated and reset, they are threadedly connected to the wall 1 through the first bolt 6. If the waterproof sleeve 3 needs to be replaced later, the two first bolts 6 can be directly removed, and the waterproof sleeve 3 can be taken out from the mounting hole 9, which is convenient and quick.

[0050] If the waterproof sleeve 3 does not need to be disassembled later, in order to further improve the stability of the connection between the waterproof sleeve 3 and the mounting hole 9 and the waterproof performance of the waterproof sleeve 3 to the pipe body 2, a hose filled with adhesive or waterproof coating can be inserted into the guide groove 8 after the waterproof sleeve 3 is installed. The adhesive or waterproof coating inside the hose is transported to the guide groove 8 through an external conveying mechanism, and flows into the interior of the multiple arc grooves 11. After the adhesive or waterproof coating dries and solidifies, there is an obstacle between the inner wall of the mounting hole 9 and the waterproof sleeve 3, and the connection between the waterproof sleeve 3 and the mounting hole 9 is more stable, further improving the protective effect of the waterproof sleeve 3 on the pipe body 2.

[0051] After the waterproof sleeve 3 is installed, dust, concrete blocks or other debris will inevitably exist on the inner wall of the movable sleeve 15. These debris will affect the use effect of the movable sleeve 15 and will also affect the daily use of the pipeline body 2. The linear motors inside the two slide grooves 12 can be controlled to start, driving the two sliders 13 inside the two slide grooves 12 to move away from each other, driving the two movable sleeves 15 to slide out from the inside of the waterproof sleeve 3, making it convenient for the staff to clean the debris on the inner wall of the movable sleeve 15, thereby facilitating the subsequent use of the movable sleeve 15 and the pipeline body 2.

[0052] After the debris inside the movable sleeve 15 is cleaned, the pipe body 2 needs to be passed through the interior of the movable sleeve 15 for laying. Before passing the pipe body 2 through the movable sleeve 15, please refer to Figure 4 and Figure 5 As shown, the second bolts 19 between the connecting plates 17 and the connecting block 14 at both ends of the movable plate 16 at the right end are removed, and the connecting plates 17 at both ends of the movable plate 16 at the right end are rotated toward each other. Then, the movable plate 16 can be rotated 180 degrees with the movable sleeve 15 as the center inside the right end cavity 18, driving the arc-shaped support plate 20 and other components to rotate upward, so that the arc-shaped support plates 20 at the left and right ends are in an upper and lower staggered state. At this time, when one end of the pipe body 2 is transported from the left end to the right end of the waterproof sleeve 3, the two arc-shaped support plates 20 can respectively abut against the outer wall of the pipe body 2 from the upper and lower ends, so that the pipe body 2 is in a central position when passing through the interior of the waterproof sleeve 3, ensuring that the pipe body 2 and the movable sleeve 15 are in a stable state. The spacing between the inner walls is the same, which prevents the pipe body 2 from being too close to the movable sleeve 15 during use, which may easily bring adverse effects to the movable sleeve 15, and can improve the aesthetics between the pipe body 2 and the waterproof sleeve 3, indirectly improving the applicability of the waterproof sleeve 3; after the pipe body 2 passes through the interior of the two movable sleeves 15, the two arc-shaped support plates 20 are kept in an up and down dislocation state, and the two rotating parts are twisted to drive the two screws 23 and the arc-shaped support plates 20 to move in the direction close to the pipe body 2, so that the two arc-shaped support plates 20 clamp and fix the pipe body 2, avoiding the pipe body 2 being easily affected by the settlement of the wall 1 itself or other factors during use, resulting in the problem of poor working stability of the pipe body 2.

[0053] Moreover, when the above-mentioned pipe body 2 passes through the interior of the waterproof sleeve 3, the air bags 25 located inside the two movable sleeves 15 are in an inflated state. When the pipe body 2 passes through the circular hole inside the air bags 25, the dust and other debris on the surface of the pipe body 2 can be automatically cleaned off, which is convenient for subsequent staff to identify the logo sprayed on the surface of the pipe body 2, and avoids the problem that after the pipe body 2 is installed, the sprayed logo is blocked by dust and other debris on the surface, which affects the staff's ability to identify the function of the pipe body 2.

[0054] When the pipe body 2 and the waterproof sleeve 3 are in normal use, due to the large gap between the interior of the movable sleeve 15 and the pipe body 2, although small animals such as mice in the outside cannot move to other locations through the waterproof sleeve 3, mice and other small animals will stay and rest in this space. During the process of staying and resting in the movable sleeve 15, mice and other small animals will produce feces, which will corrode the inner wall of the movable sleeve 15 and the outer wall of the pipe body 2, affecting the use of the pipe body 2. After the small animals such as mice enter the interior of the movable sleeve 15, the slider 13 can drive the movable sleeve 15 to move back and forth repeatedly inside the waterproof sleeve 3 to drive away the mice inside the movable sleeve 15. In the process of the mobile sleeve 15 moving back and forth, the arc-shaped support plate 20 is driven back and forth together, so that the raised portion 22 on the top of the arc-shaped support plate 20 and the pipe body 2 generate friction and noise, further improving the efficiency of driving away mice and preventing mice from having an adverse effect on the use of the pipe body 2.

[0055] If welding maintenance is required at a position near the waterproof sleeve 3 of the pipe body 2, in order to avoid the sparks generated by welding the pipe body 2 from constantly falling downward, which may easily cause a safety hazard, during the welding of the pipe body 2, the slider 13 can be moved in the slide groove 12 to drive the movable sleeve 15 to move to the end of the waterproof sleeve 3, and the second bolt 19 between the connecting plate 17 at both ends of the movable plate 16 and the connecting block 14 is removed. At this time, the movable plate 16 can be pulled out of the cavity 18 to move and extend, so that the movable plate 16 located below the welding part of the pipe body 2 can block the sparks falling from the welding pipe body 2, thereby reducing the chance of sparks falling to the surface of the flammable items below and causing a fire.

[0056] After the welding of the pipe body 2 is completed, welding slag will inevitably adhere to the vicinity of the welding part of the pipe body 2. In order to prevent the welding slag from corroding the surface of the pipe body 2, the movable plate 16 can be pushed to rotate in the cavity 18, driving the outer wall of one side of the arc-shaped support plate 20 with the protrusion 22 to rub against the outer wall of the pipe body 2, so that the welding slag on the surface of the pipe body 2 can be cleaned; if the welding part is the connection part of the two pipe bodies 2, the scraper 21 on the outer wall of one side of the arc-shaped support plate 20 and the welding part of the connector higher than the pipe body 2 can be used to clean the welding slag on the outer wall of the connector, thereby improving the service life of the pipe body 2.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.

A waterproof structure for wall-penetrating pipes according to claim 2, characterized in that: Two rotating blocks (5) are rotatably mounted on the other end of the waterproof sleeve (3), and both rotating blocks (5) are threadedly connected to the outer wall of the other side of the wall (1) via a first bolt (6).

4. A waterproof structure for wall-penetrating pipes according to claim 3, characterized in that: The outer wall of the waterproof sleeve (3) is provided with a plurality of guide grooves (8), and the outer wall of the waterproof sleeve (3) is also provided with a plurality of arc grooves (11) connected with the guide grooves (8).

5. A waterproof structure for wall-penetrating pipes according to claim 4, characterized in that: Two fixing rods (4) are installed at both ends of the waterproof sleeve (3); the outer walls of the two fixing rods (4) on the side close to each other and the inner wall of the waterproof sleeve (3) are provided with a sliding groove (12); the outer walls of the two movable sleeves (15) are installed with two sliders (13) that can slide back and forth in the sliding groove (12).

6. A construction method for a wall-penetrating pipe waterproof structure, characterized in that: The construction method includes the waterproof structure of claim 5, and further includes the following steps: Step 1: Rotate the two rotating blocks (5) toward each other, then pass one end of the waterproof sleeve (3) with the rotating block (5) through the mounting hole (9), so that the two fixed blocks (7) can enter the interior of the groove (10), and finally rotate the two rotating blocks (5) back to their original positions, and then connect them to the wall (1) through the first bolt (6) through a threaded connection; Step 2: In order to improve the stability of the connection between the waterproof sleeve (3) and the mounting hole (9) and the waterproof performance of the waterproof sleeve (3) to the pipe body (2), after the waterproof sleeve (3) is installed, a hose filled with adhesive or waterproof coating is inserted into the guide groove (8), and the adhesive or waterproof coating inside the hose is transported into the guide groove (8) by an external transport mechanism, and flows into the interior of the plurality of arc grooves (11). After the adhesive or waterproof coating is dried and solidified, an obstacle is formed between the inner wall of the mounting hole (9) and the waterproof sleeve (3), and the connection between the waterproof sleeve (3) and the mounting hole (9) is more stable. Step 3: After the waterproof sleeve (3) is installed, the linear motors inside the two slide grooves (12) are controlled to start, driving the two sliders (13) inside the two slide grooves (12) to move away from each other, driving the two movable sleeves (15) to slide out from the inside of the waterproof sleeve (3), making it convenient for the staff to clean the debris on the inner wall of the movable sleeve (15), thereby facilitating the subsequent use of the movable sleeve (15) and the pipeline body (2); Step 4: After the debris inside the movable sleeve (15) is cleaned, the pipe body (2) needs to be laid through the inside of the movable sleeve (15), and one of the movable plates (16) is controlled to rotate with the movable sleeve (15) as the center, driving the arc support plate (20) and other components to rotate upward, so that the arc support plates (20) at the left and right ends are in an up-down misaligned state. At this time, when one end of the pipe body (2) is transported from the left end to the right end of the waterproof sleeve (3), the two arc support plates (20) can respectively contact the outer wall of the pipe body (2) from the upper and lower ends, so that the pipe body (2) is in a central position when passing through the inside of the waterproof sleeve (3), ensuring that the distance between the pipe body (2) and the inner wall of the movable sleeve (15) is the same, and avoiding the pipe body (2) being too close to the movable sleeve (15) during use, which is easy to bring adverse effects to the movable sleeve (15).
