Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a sliding sleeve device and installation method for pressure pipeline anti-settlement wells. Background Technology

[0002] Currently, building construction projects refer to the physical structures of buildings and their supporting electrical, piping, and other ancillary facilities. Qualified and effective building projects all rely on these ancillary electromechanical facilities. In the early stages of construction, when municipal pipelines for water supply, drainage, gas, and heating are connected to the building, wall sleeves play a crucial role as the primary connection channels. However, over time, with the differential settlement of the building's internal and external foundations, the municipal pipelines outside the wall sleeves frequently experience breakage, deformation, and pull-out under the shear force generated by this differential settlement, severely impacting the normal operation of the infrastructure system.

[0003] Outdoor pipe penetration sleeves, which connect indoor and outdoor pipelines, are crucial nodes in infrastructure systems. During the design and construction of general building projects, various soft soil treatment measures are implemented based on geological surveys to effectively ensure the safety and stability of the main structure. Buildings, structures, and heavy-duty driveways supported by pile foundations will not experience settlement.

[0004] However, due to the constraints of the construction environment, the excavation and backfilling work for the main structure foundation is difficult to achieve the same anti-settlement requirements as the main building in some areas. In particular, coastal and riverside areas are subject to water erosion all year round, and are characterized by poor gradation, rich and saturated water content, loose silty gravel, clay and silt. Due to the special environment, differential settlement is more severe in these areas, resulting in serious quality problems in the pipe connections at the external wall sleeves of the building.

Detailed Implementation

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] Reference Figures 1 to 6 as well as Figures 10 to 12This invention discloses a sliding sleeve device 1 for a pressure pipeline anti-settlement well, comprising a sliding component 10 and two pre-embedded tracks 20 arranged opposite each other. The two pre-embedded tracks 20 are pre-embedded in the wall 2 of the anti-settlement well, and the wall 2 has a reserved hole 21. The two pre-embedded tracks 20 are arranged opposite each other on both sides of the reserved hole 21. One end of the sliding component 10 is inserted into the two pre-embedded tracks 20 on opposite sides, and the sliding component 10 can slide along the pre-embedded tracks 20. The other end of the sliding component 10 is inserted into the reserved hole 21. 0 is used to connect to one end of pipe 3, and the other end of pipe 3 is used to connect to metal hose 4. The sliding component 10 can slide with the settlement of pipe 3. By setting the sliding component 10 to slide downward with the settlement of pipe 3, the pressure relief protection is provided for pipe 3 which is at risk of settlement, thereby solving the problems of pipe 3 interface pull-out, pipe body deformation, tearing and other problems caused by differential settlement. It greatly protects the quality of the interface between pipe 3 and metal hose 4, improves the safety and stability of pipe 3 when passing through differential settlement zone, and ensures the safe operation of pipe 3.

[0037] During use, one end of pipe 3 is inserted into sliding assembly 10, and the other end of pipe 3 is connected to metal hose 4 through flange.

[0038] It should be noted that the reserved hole 21 is a rectangular hole with dimensions of 660mm × 290mm.

[0039] The sliding sleeve device 1 provided in this embodiment is used as follows: when the pipe 3 sinks downward, the sliding component 10 slides downward along with the pipe 3 to avoid the pipe 3 from being pulled apart, deformed, or torn at the connection between the pipe 3 and the metal hose 4, which greatly improves the quality of the interface between the pipe 3 and the metal hose 4.

[0040] Furthermore, in this embodiment, the pre-embedded track 20 includes a slide rail 201 and at least one pre-embedded rod 202. One end of the pre-embedded rod 202 is connected to the back of the slide rail 201, and the other end of the pre-embedded rod 202 is used to be embedded in the wall 2. One end of the sliding component 10 is inserted into the side of the slide rail 201 away from the pre-embedded rod 202, and the sliding component 10 can slide along the slide rail 201.

[0041] Specifically, the extension direction of the embedded rod 202 is set perpendicular to the extension direction of the slide rail 201.

[0042] To improve the stability of the connection between the embedded track 20 and the wall 2, the embedded track 20 includes a slide rail 201 and two embedded rods 202. The two embedded rods 202 are both set on the back of the slide rail 201 and are spaced apart along the length of the slide rail 201.

[0043] For example, the embedded rod 202 can be made of steel bars, or of course, iron rods can also be used.

[0044] For example, slide rail 201 can be made of C-shaped steel, or of course, slide rail 201 can also be made of I-shaped steel.

[0045] Continue to refer to Figures 7 to 12 In this embodiment, the sliding assembly 10 includes a sliding unit 101 and a mounting unit 102. The sliding unit 101 has a mounting hole adapted to the mounting unit 102. One end of the mounting unit 102 abuts against the end of the mounting hole. The mounting unit 102 and the sliding unit 101 are detachably connected. The end of the mounting unit 102 facing away from the sliding unit 101 is used to be inserted into the reserved hole 21. The opposite sides of one end of the sliding unit 101 are respectively inserted into two pre-embedded tracks 20. The sliding unit 101 can slide along the pre-embedded tracks 20. The end of the pipe 3 facing away from the metal flexible hose 4 is used to be inserted into the mounting unit 102.

[0046] Specifically, the two opposite sides of one end of the sliding unit 101 are respectively inserted into the two slide rails 201. During use, the pipe 3 sinks downward, the pipe 3 drives the installation unit 102 to move downward, and the installation unit 102 drives the sliding unit 101 to slide downward along the slide rail 201 to the preset position.

[0047] Furthermore, in this embodiment, the mounting unit 102 includes a sleeve 1021 and a plurality of mounting bolts 1022.

[0048] During use, the center line of the sleeve 1021 is set parallel to the center line of the mounting hole. In some feasible ways, the center line of the sleeve 1021 is set collinear with the center line of the mounting hole.

[0049] One end of the sleeve 1021 abuts against the end of the mounting hole, the sleeve 1021 is connected to the sliding unit 101 by the mounting bolt 1022, and the other end of the sleeve 1021 is used to be inserted into the reserved hole 21.

[0050] During use, one end of pipe 3 is inserted into sleeve 1021, and the other end of pipe 3 is connected to metal flexible hose 4 through flange.

[0051] For example, the mounting unit 102 includes a sleeve 1021 and eight M12 mounting bolts 1022, all of which are welded to the end of the sleeve 1021.

The multiple bolt holes surround the outside of the mounting hole, and the bolt holes and mounting bolts 1022 are arranged one-to-one. The sleeve 1021 is welded with one end of the mounting bolt 1022 abutting against the end of the mounting hole. The mounting bolt 1022 is inserted into the bolt hole, and the sleeve 1021 is connected to the sliding plate 1011 through the mounting bolt 1022.

[0053] It should be noted that the number of bolt holes is basically the same as the number of mounting bolts 1022.

[0054] Specifically, the slide plate 1011 is set parallel to the wall 2. During use, one side of the slide plate 1011 is attached to the wall 2, one end of the sleeve 1021 is abutted in the mounting hole, and the other end of the sleeve 1021 is inserted into the reserved hole 21. Multiple mounting bolts 1022 are respectively inserted into multiple bolt holes.

[0055] For example, the mounting hole can be made at the geometric center of the skateboard 1011, but of course, the mounting hole can also be made at other locations on the skateboard 1011.

[0056] The two connecting groups are respectively set at opposite ends on one side of the slide plate 1011. The ends of the two connecting groups away from the slide plate 1011 are respectively inserted into the two pre-embedded slide rails 201, and the connecting groups can slide along the slide rails 201.

[0057] Furthermore, in this embodiment, the connecting assembly includes a plurality of sliding bolts 1012, one end of each of the plurality of sliding bolts 1012 being disposed on one side of the slide plate 1011, and the plurality of sliding bolts 1012 being spaced apart along the length direction of the slide plate 1011. During use, the ends of the plurality of sliding bolts 1012 facing away from the slide plate 1011 are all inserted into the corresponding slide rails 201.

[0058] In this embodiment, the connecting group includes five sliding bolts 1012, one end of each of the five sliding bolts 1012 is disposed on one side of the slide plate 1011, and the five sliding bolts 1012 are spaced apart along the length of the slide plate 1011.

[0059] For example, the sliding bolt 1012 can be of type M12, but of course, other types of sliding bolts 1012 can also be used.

[0060] Specifically, five [unclear] are installed at each end of one side of the skateboard 1011. The holes were drilled, and five M12 sliding bolts 1012 were respectively inserted into the five holes. Inside the hole.

[0061] For example, skateboard 1011 can be made of steel plate, or of course, skateboard 1011 can be made of iron plate.

[0062] Continue to refer to Figures 6 to 13 Another embodiment provides an installation method for a sliding sleeve device 1 for a pressure pipeline anti-settlement well, comprising the following steps:

[0063] S101, Fabricate and install unit 102.

[0064] Specifically, S101, fabricating the installation unit 102, includes: welding eight M12 mounting bolts 1022 evenly onto the outer peripheral wall of the end of the sleeve 1021.

[0065] S102, Make sliding unit 101.

[0066] Specifically, S102, manufacturing the sliding unit 101, includes: drilling 5 holes at each of the opposite ends of one side of the skateboard 1011. The holes will be used to insert five M12 sliding bolts 1012 into the five holes respectively. Inside the hole.

[0067] S103. Mount the mounting unit 102 onto the sliding unit 101.

[0068] Specifically, a mounting hole and eight equally spaced bolt holes are made at the geometric center of the slide plate 1011, and one end of the sleeve 1021 is abutted against the end of the mounting hole. Eight mounting bolts 1022 are respectively inserted into the eight bolt holes. The sleeve 1021 is connected to the slide plate 1011 through the mounting bolts 1022. The size of the mounting hole is based on the inner diameter of the sleeve 1021.

[0069] S104. Insert the two opposite ends of the sliding unit 101 into the two pre-embedded tracks 20 respectively.

[0070] Specifically, the sliding bolt 1012 is installed inside the slide rail 201 and temporarily tightened for later use.

[0071] During the pouring of wall 2, the pre-embedded track 20 is embedded in advance, and the sliding bolt 1012 is loosened after the installation and backfilling of the pipe 3 in the outdoor area prone to settlement is completed.

[0072] The sliding sleeve device 1 for pressure pipeline anti-settlement wells provided in this application includes a sliding component 10 and two pre-embedded tracks 20 arranged opposite each other. The two pre-embedded tracks 20 are pre-embedded in the wall 2 of the anti-settlement well. The wall 2 has a reserved hole 21.
