Description

Technical Field

[0001] This utility model relates to the field of settling instruments, specifically to the installation structure of a telescopic settling protection pipe for vertical tension lines. Background Technology

[0002] In dam safety monitoring design, most monitoring items, including dam settlement and deformation monitoring, still rely primarily on traditional methods and techniques. The Shuangjiangkou Hydropower Station project employs various monitoring instruments, including water-tube settlement meters, electromagnetic settlement meters, and beam settlement meters, to monitor the corresponding vertical displacements within the core wall dam body. Dam settlement and internal stress are crucial control indicators affecting the construction quality and operational safety of earth-rock dams. For high rockfill dams, under high stress, their deformation and stress changes are not only greater than other rockfill dams, but they may also experience some abnormal problems.

[0003] The inventors discovered that at least the following problems remain unresolved in the existing technology: Due to the large confining pressure inside the core wall of a rockfill dam, the deformation of traditionally welded pipe connections is not well-suited to this characteristic. While buried pipes are connected using a sleeve connection method, during installation, smaller pipes are prone to sliding within larger pipes, affecting the stability of the installation. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an installation structure for a vertical tension line telescopic settlement protection pipe, so as to solve the technical problem that small pipes are prone to sliding inside large pipes during the current pipeline laying process, which affects the stability of pipeline installation.

[0005] To achieve the purpose of this utility model, the technical solution adopted is as follows: The installation structure of the vertical tension line telescopic settlement protection pipe is designed, including a large pipe and a small pipe, which are movably connected; the installation mechanism is used to improve the installation stability of the large and small pipes, and includes a balance plate, a support plate, an observation platform, and a rock base. The lower part of the large pipe vertically penetrates the middle of the balance plate and is welded to it. The upper end of the small pipe vertically penetrates the middle of the support plate and is welded to it. The middle of both ends of the upper surface of the balance plate is vertically... The support column is welded, and the tops of the two sets of support columns are welded to the middle of both sides of the lower surface of the observation platform. The outer side of the support plate has a first positioning hole that runs horizontally from top to bottom, and the outer side of the left support column has a second positioning hole that runs horizontally. The support column and the support plate are fixedly connected by positioning screws that pass through the first and second positioning holes. Sealing mechanism: used for sealing the insertion ends of the large and small pipes. The sealing mechanism includes a bellows. The bottom end of the bellows is fixedly connected to the top end of the large pipe, and the top end of the bellows is fixedly connected to the bottom side of the support plate.

[0006] Preferably, fixing holes are evenly provided on the outer side of the bottom end of the large pipe, and the rock base is fixedly connected to the large pipe by fixing bolts passing through the fixing holes.

[0007] Preferably, a second guide groove is provided through the lower end of the large pipe, and a first guide groove is provided through the middle of the upper surface of the observation platform, with the first guide groove aligned with the top end of the small pipe.

[0008] Preferably, the second positioning holes are evenly distributed from top to bottom on the upper end of the support column, and the first positioning holes and the second positioning holes correspond to each other.

[0009] Preferably, the corrugated pipe is sleeved on the outside of the small pipe, and the size of the corrugated pipe matches that of the small pipe.

[0010] Preferably, a rubber ring is bonded to the outer side of the bottom end of the small pipe, and the rubber ring is in contact with the inner wall of the large pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model inserts a small pipe into a large pipe for a certain length, creating a deformation space between the two pipes to accommodate deformation under high confining pressure. A balance plate horizontally welded to the lower part of the large pipe allows the soil's own weight to correct any deviation from the vertical direction under uneven confining pressure. Two sets of support columns fix the balance plate to the observation platform, enabling simultaneous installation of the protective pipe and the observation platform for convenience and speed. Positioning screws passing through the first and second positioning holes position the small pipe in the middle of the support plate, improving stability during installation. After installation, the positioning screws are removed, and the support plate supports the small pipe, preventing it from slipping into the large pipe.

[0013] 2. This utility model improves the sealing performance of the connection between the small pipe and the inner wall of the large pipe by using a rubber ring on the outer side of the bottom end of the small pipe, thus achieving water-blocking sealing. By fixing the two ends of the corrugated pipe to the top of the large pipe and the bottom side of the support plate respectively, it can effectively protect the splice ends of the small pipe and the large pipe.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] For the installation structure of the vertical tension line expansion joint settlement protection pipe, please refer to [reference needed]. Figures 1 to 3 The system includes a large pipe 1 and a small pipe 11, which are movably connected. The installation mechanism, used to improve the installation stability of the large and small pipes 11, includes a balance plate 12, a support plate 16, an observation platform 13, and a rock base 23. The lower part of the large pipe 1 vertically penetrates the middle of the balance plate 12 and is welded to it. The upper end of the small pipe 11 vertically penetrates the middle of the support plate 16 and is welded to it. Support columns 1 are vertically welded to the middle of both ends of the upper surface of the balance plate 12. 4. The tops of the two sets of support columns 14 are welded to the middle of the two sides of the lower surface of the observation platform 13 respectively. The outer side of the support plate 16 is provided with a first positioning hole 17 horizontally through from top to bottom. The outer side of the left support column 14 is provided with a second positioning hole 18 horizontally through from top to bottom. The second positioning holes 18 are evenly distributed at the upper end of the support column 14 from top to bottom. The first positioning hole 17 and the second positioning hole 18 correspond to each other. The support column 14 and the support plate 16 are fixedly connected by positioning screws 19 through the first positioning hole 17 and the second positioning hole 18.

[0020] The small pipe 11 is movably connected to the large pipe 1, and the bottom end of the small pipe 11 is inserted into the large pipe 1 for a certain length, so that there is a certain deformation space between the two pipes, which can adapt to a certain deformation under high confining pressure. The balance plate 12 horizontally welded to the lower part of the large pipe 1 allows the pipe to be corrected by the weight of the soil under the action of unbalanced confining pressure. The balance plate 12 is fixedly connected to the observation platform 13 by two sets of support columns 14. The observation platform 13 is installed at the same time as the protective pipe is installed, which is convenient and quick. The positioning screw 19 passes through the first positioning hole 17 and the second positioning hole 18 to position the small pipe 11 in the middle of the support plate 16, which improves the stability of the small pipe 11 and the large pipe 1 during the installation process. After the installation is completed, the positioning screw 19 is removed to release the fixation of the small pipe 11. The support plate 16 can support the small pipe 11 and prevent the small pipe 11 from sliding into the large pipe 1.

[0021] For details, see Figures 1 to 3Fixing holes 22 are evenly provided on the outer side of the bottom end of the large pipe 1. The rock base 23 is fixedly connected to the large pipe 1 through the fixing holes 22 by fixing bolts 24. A second guide groove 25 is provided through the lower end of the large pipe 1. A first guide groove 15 is provided through the middle of the upper surface of the observation platform 13. The first guide groove 15 is aligned with the top end of the small pipe 11.

[0022] Insert the bottom end of the large pipe 1 into the rock base 23, and then fix the bottom end of the large pipe 1 to the rock base 23 by passing the fixing bolt 24 through the fixing hole 22. The indium steel wire for fixing the settlement anchor plate passes through the second guide groove 25 at the lower end of the large pipe 1. After the indium steel wire enters the interior of the large pipe 1, it passes through the small pipe 11 and connects to the corresponding measuring component through the first guide groove 15 in the middle of the observation platform 13.

[0023] Further, see Figures 1 to 3 Sealing mechanism: used for sealing the joint ends of the large pipe 1 and the small pipe 11. The sealing mechanism includes a bellows 2. The bottom end of the bellows 2 is fixedly connected to the top end of the large pipe 1. The top end of the bellows 2 is fixedly connected to the bottom side of the support plate 16. The bellows 2 is sleeved on the outside of the small pipe 11, and the size of the bellows 2 matches that of the small pipe 11. A rubber ring 21 is bonded to the outside of the bottom end of the small pipe 11. The rubber ring 21 is in contact with the inner wall of the large pipe 1.

[0024] The rubber ring 21 on the outer side of the bottom end of the small pipe 11 can improve the sealing performance of the connection between the small pipe 11 and the inner wall of the large pipe 1, achieving a water-blocking seal. The two ends of the corrugated pipe 2 are fixedly connected to the top end of the large pipe 1 and the bottom side of the support plate 16, respectively, which can effectively protect the insertion end of the small pipe 11 and the large pipe 1. It should be noted that the corrugated pipe 2 can be made of rubber material and does not affect the connection between the large pipe 1 and the small pipe 11.
