Description

Technical Field

[0001] This invention belongs to the field of civil engineering tunnel construction technology, and in particular relates to a grouting pipe for civil engineering tunnels that is easy to install and disassemble. Background Technology

[0002] In civil engineering tunnel construction, grouting plays a crucial role in reinforcing the soil, filling voids, and enhancing the waterproofing performance of the tunnel structure. As a key component for grouting, the performance of the grouting pipe directly affects the quality and progress of the entire tunnel project. Currently, the traditional grouting pipe technology widely used in various civil engineering tunnel construction projects is relatively mature and can meet certain basic grouting requirements.

[0003] However, in actual construction, traditional grouting pipes for civil engineering tunnels have revealed obvious defects, especially in the installation and dismantling process. During installation, the connection method of traditional grouting pipes is complicated, usually requiring construction personnel to perform precise alignment and sealing operations. This not only consumes a lot of manpower and time, but also places high demands on the professional skills and experience of the construction personnel. If the operation is not done properly, problems such as loose connection and poor sealing can easily occur.

[0004] To address these issues, we offer easily installable and disassembled grouting pipes for civil engineering tunnels. Summary of the Invention

[0005] The purpose of this invention is to provide a grouting pipe for civil engineering tunnels that is easy to install and disassemble. By combining a snap-fit ​​mechanism and a self-locking mechanism, the problem that existing grouting pipes for civil engineering tunnels do not have the function of easy installation and disassembly is solved.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0007] This invention relates to a grouting pipe for civil engineering tunnels that is easy to install and disassemble. It includes a grouting section, a connecting section connected to one side of the grouting section, a conveying pipe provided to one side of the connecting section, a sealing mechanism between the conveying pipe and the connecting section, a snap-fit ​​mechanism on the surfaces of the conveying pipe and the connecting section, and a self-locking mechanism on one side of the snap-fit ​​mechanism. The snap-fit ​​mechanism includes an annular inclined plate and a support block. The annular inclined plate is fixedly sleeved on the surface of the conveying pipe, and the support block is fixed to the surface of the connecting section. A threaded rod is movably connected to the surface of the support block via a bearing. A movable sleeve is threadedly connected to the surface of the threaded rod. A first support plate is fixedly connected to one side of the movable sleeve, and a transmission rod is fixedly connected to the bottom of the first support plate. An inclined block is fixedly connected to the bottom of the transmission rod. The self-locking mechanism includes a housing fixed to the surface of the connecting section. A movable plate is slidably connected to the inner wall of the housing. A limit plate is fixedly connected to one side of the movable plate, and a crossbar is fixedly connected to the other side of the movable plate. A spring is fixedly connected to the bottom of the other side of the movable plate, and the end of the spring away from the movable plate is fixedly connected to the inner wall of the housing.

[0008] When connecting the delivery pipe and the connecting part, the construction personnel only need to rotate the threaded rod. The rotation of the threaded rod drives the moving sleeve to move along its axial direction. The movement of the moving sleeve is transmitted through the first support plate and the transmission rod, causing the inclined block to press against the annular inclined plate, thereby making the delivery pipe and the connecting part in tight contact. The whole process is simple to operate and does not require precise alignment. The construction personnel only need to operate the threaded rod to complete the connection, which greatly improves the installation efficiency and reduces the requirements for the professional skills and experience of the construction personnel. After the inclined block presses against the annular inclined plate to tightly connect the delivery pipe and the connecting part, the continued movement of the moving sleeve will drive the locking plate to move downward. The locking plate presses against the limiting plate, causing the limiting plate to drive the moving plate to move and compress the spring. When the locking plate moves below the limiting plate, the elastic potential energy of the spring will reset the limiting plate, thereby limiting the locking plate and locking the height of the inclined block. This self-locking function prevents the connection between the inclined block and the annular inclined plate from loosening, ensuring the stability of the connection between the delivery pipe and the connecting part. Even in the complex environment of tunnel construction, it can ensure the normal operation of the grouting pipe body and improve the reliability of the tunnel grouting project.

[0009] The invention is further configured such that a handwheel is fixedly connected to the top of the threaded rod, and the surface of the handwheel is provided with anti-slip texture. The handwheel fixed to the top of the threaded rod makes it convenient for construction personnel to rotate the threaded rod, and the anti-slip texture on the surface of the handwheel increases friction, making operation more labor-saving and convenient, and improving installation efficiency.

[0010] The present invention is further configured such that a second support plate is fixedly connected to the other side of the movable sleeve, a slide rod is fixedly connected to the surface of the second support plate, a slide sleeve is slidably connected to the surface of the slide rod, the slide sleeve is fixed to the surface of the support block, and a snap-fit ​​plate is fixedly connected to the bottom of the slide rod. The second support plate, slide rod and slide sleeve connected to the movable sleeve can limit the movable sleeve, improve the stability of the movable sleeve when it moves up and down, ensure the stable operation of the snap-fit ​​mechanism, and thus ensure the reliability of the connection between the conveying pipe and the connecting part.

[0011] The invention is further configured such that a side plate is fixedly connected to the end of the crossbar away from the moving plate, and a pull ring is fixedly connected to the end of the side plate away from the crossbar. The side plate and pull ring connected to the crossbar facilitate the construction personnel to pull the crossbar, thereby controlling the moving plate and the limiting plate, making it easier to unlock the snap-fit ​​plate, facilitating disassembly, and improving disassembly efficiency.

[0012] The present invention is further configured such that the connecting part includes a connecting pipe, the connecting pipe is connected to the grouting part, and a limiting plate is fixedly sleeved on the surface of the connecting pipe. The connecting pipe of the connecting part is connected to the grouting part, and the fixedly sleeved limiting plate can play a protective and limiting role.

[0013] The invention is further configured such that the grouting part includes a grouting pipe body, the grouting pipe body is connected to a connecting pipe, and the surface of the grouting pipe body is provided with uniformly distributed grouting holes. The uniformly distributed grouting holes on the surface of the grouting pipe body of the grouting part ensure the uniformity of grouting, improve the grouting effect, and ensure the reinforcement and waterproofing performance of the tunnel soil.

[0014] The present invention is further configured such that the sealing mechanism includes a sealing groove, the sealing groove is formed on one side of the grouting pipe body, a sealing gasket is provided in the inner cavity of the sealing groove, and one side of the sealing gasket is fixedly connected to one side of the delivery pipe. The sealing groove and sealing gasket of the sealing mechanism structurally ensure the sealing performance of the connection between the delivery pipe and the grouting pipe body. The operation is simple and avoids the problem of poor sealing caused by improper sealing operation in the traditional method.

[0015] The invention is further configured such that a through groove is provided on one side of the housing for use with a limiting plate, and a through hole is provided on the other side of the housing for use with a crossbar. The through groove and through hole provided in the housing are used in conjunction with the limiting plate and the crossbar, respectively, so that the operation of the self-locking mechanism is smoother, easier for construction personnel to operate, and improves the convenience of installation and disassembly.

[0016] The present invention has the following beneficial effects.

[0017] 1. After the delivery pipe and the connecting pipe of the present invention are connected, the sealing groove and the sealing gasket fit together tightly, which ensures the sealing of the connection part from the structure. There is no need for complicated sealing operation procedures. By turning the handwheel to drive the threaded rod, the delivery pipe and the connecting pipe can be tightly connected by using a simple mechanical transmission principle. The operation is simple, reducing the difficulty of construction and time cost, and the sealing effect of the connection is further enhanced during the connection process.

[0018] 2. The sliding rod and sliding sleeve of this invention effectively limit the moving sleeve, improve the stability of the moving sleeve during movement, ensure the stable operation of the snap-fit ​​mechanism, and make the connection more reliable. The unique self-locking design, under the interaction of the snap-fit ​​plate and the limiting plate, uses the elastic potential energy of the spring to lock the height of the inclined block, avoids the connection between the inclined block and the annular inclined plate from loosening, and ensures the stability and safety of the entire grouting pipe body during use.

[0026] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments. Example

[0027] Please see Figure 1-5 This invention relates to a grouting pipe for civil engineering tunnels that is easy to install and disassemble. It includes a grouting section 1, a connecting section 2 connected to one side of the grouting section 1, a conveying pipe 3 disposed on one side of the connecting section 2, a sealing mechanism 4 disposed between the conveying pipe 3 and the connecting section 2, a snap-fit ​​mechanism 5 disposed on the surfaces of the conveying pipe 3 and the connecting section 2, and a self-locking mechanism 6 disposed on one side of the snap-fit ​​mechanism 5. The snap-fit ​​mechanism 5 includes an annular inclined plate 501 and a support block 502. The annular inclined plate 501 is fixedly sleeved on the surface of the conveying pipe 3, and the support block 502 is fixed to the surface of the connecting section 2. A threaded rod 503 is movably connected to the surface of the support block 502 via a bearing, and a sliding contact is threaded onto the surface of the threaded rod 503. The movable sleeve 504 has a first support plate 505 fixedly connected to one side, a transmission rod 506 fixedly connected to the bottom of the first support plate 505, and an inclined block 507 fixedly connected to the bottom of the transmission rod 506; the self-locking mechanism 6 includes a housing 601, which is fixed to the surface of the connecting part 2. A movable plate 602 is slidably connected to the inner wall of the housing 601. A limit plate 603 is fixedly connected to one side of the movable plate 602, and a crossbar 604 is fixedly connected to the other side of the movable plate 602. A spring 605 is fixedly connected to the bottom of the other side of the movable plate 602, and the end of the spring 605 away from the movable plate 602 is fixedly connected to the inner wall of the housing 601.

[0028] Specifically: When connecting the conveying pipe 3 and the connecting part 2, the construction personnel only need to rotate the threaded rod 503. The rotation of the threaded rod 503 drives the moving sleeve 504 to move along its axial direction. The movement of the moving sleeve 504 is transmitted through the first support plate 505 and the transmission rod 506, causing the inclined block 507 to press against the annular inclined plate 501, thereby making the conveying pipe 3 and the connecting part 2 in close contact. The whole process is simple to operate and does not require precise alignment. The construction personnel only need to operate the threaded rod 503 to complete the connection, which greatly improves the installation efficiency and reduces the requirements for the professional skills and experience of the construction personnel. After the inclined block 507 presses against the annular inclined plate 501 to make the conveying pipe 3 and the connecting part 2 in close connection, the moving sleeve 504... The continued movement of 04 will cause the locking plate 5044 to move downward. The locking plate 5044 presses the limiting plate 603, causing the limiting plate 603 to move the moving plate 602 and compress the spring 605. When the locking plate 5044 moves below the limiting plate 603, the elastic potential energy of the spring 605 causes the limiting plate 603 to reset, thereby limiting the locking plate 5044 and locking the height of the inclined block 507. This self-locking function prevents the connection between the inclined block 507 and the annular inclined plate 501 from becoming loose, ensuring the stability of the connection between the delivery pipe 3 and the connecting part 2. Even in the complex environment of tunnel construction, it can ensure the normal operation of the grouting pipe body 101 and improve the reliability of the tunnel grouting project. Example

[0029] Please see Figure 1-5 Based on Embodiment 1, a handwheel 5031 is fixedly connected to the top of the threaded rod 503. The surface of the handwheel 5031 is provided with anti-slip texture. A second support plate 5041 is fixedly connected to the other side of the movable sleeve 504. A sliding rod 5042 is fixedly connected to the surface of the second support plate 5041. A sliding sleeve 5043 is slidably connected to the surface of the sliding rod 5042. The sliding sleeve 5043 is fixed to the surface of the support block 502. A snap-fit ​​plate 5044 is fixedly connected to the bottom of the sliding rod 5042. A side plate 6041 is fixedly connected to the end of the crossbar 604 away from the movable plate 602. A pull ring 6042 is fixedly connected to the end of the side plate 6041 away from the crossbar 604. The connecting part 2 includes a connecting pipe 20. 1. The connecting pipe 201 is connected to the grouting part 1. A limiting plate 202 is fixedly sleeved on the surface of the connecting pipe 201. The grouting part 1 includes a grouting pipe body 101, which is connected to the connecting pipe 201. The surface of the grouting pipe body 101 is provided with evenly distributed grouting holes 102. The sealing mechanism 4 includes a sealing groove 401, which is opened on one side of the grouting pipe body 101. A sealing gasket 402 is provided in the inner cavity of the sealing groove 401. One side of the sealing gasket 402 is fixedly connected to one side of the conveying pipe 3. One side of the housing 601 is provided with a through groove for use with the limiting plate 603, and the other side of the housing 601 is provided with a through hole for use with the crossbar 604.

[0030] Specifically: The handwheel 5031 fixed to the top of the threaded rod 503 facilitates the rotation of the threaded rod 503 by construction personnel. The anti-slip texture on the surface of the handwheel 5031 increases friction, making operation more labor-saving and convenient, and improving installation efficiency. The second support plate 5041, slide rod 5042, and slide sleeve 5043 connected to the movable sleeve 504 can limit the movable sleeve 504, improve the stability of the movable sleeve 504 when moving up and down, ensure the stable operation of the snap-fit ​​mechanism 5, and thus ensure the reliability of the connection between the conveying pipe 3 and the connecting part 2. The side plate 6041 and pull ring 6042 connected to the crossbar 604 facilitate the pulling of the crossbar 604 by construction personnel, thereby controlling the movable plate 602 and the limiting plate 603, facilitating the unlocking of the snap-fit ​​plate 5044, making disassembly convenient and improving disassembly efficiency. The connecting pipe 201 of the connecting part 2 is connected to the grouting part 1. The fixedly sleeved limiting plate 202 can play a protective and limiting role. The grouting pipe body 101 of the grouting part 1 has evenly distributed grouting holes 102 on its surface to ensure the uniformity of grouting, improve the grouting effect, and ensure the reinforcement and waterproofing performance of the tunnel soil. The sealing groove 401 and sealing gasket 402 of the sealing mechanism 4 ensure the sealing of the connection between the delivery pipe 3 and the grouting pipe body 101 from a structural point of view. The operation is simple and avoids the problem of poor sealing caused by improper sealing operation in the traditional method. The through groove and through hole of the shell 601 are used in conjunction with the limiting plate 603 and the crossbar 604 respectively, so that the operation of the self-locking mechanism 6 is smoother, which is convenient for construction personnel to operate and improves the convenience of installation and disassembly.

[0031] The working principle of this invention is as follows: The user connects the delivery pipe 3 to the connecting pipe 201. After connection, the sealing groove 401 and the sealing gasket 402 ensure the sealing of the connection between the delivery pipe 3 and the connecting pipe 201. Then, the user rotates the handwheel 5031, which drives the threaded rod 503 to rotate. The threaded rod 503 drives the moving sleeve 504 to move, which in turn drives the first support plate 505 to move. The first support plate 505 drives the transmission rod 506 to move, which in turn drives the inclined block 507 to press against the annular inclined plate 501. The annular inclined plate 501 is pressed, causing the delivery pipe 3 and the connecting pipe 201 to come into close contact. This achieves both the connection of the delivery pipe 3 and the connecting pipe 201 and ensures the sealing of the connection. When the moving sleeve 504 moves, it drives the second support plate 5041 to move towards the connecting pipe 201. As the second support plate 5041 moves downward, it drives the sliding rod 5042 to move downward. The sliding rod 5042, in conjunction with the sliding sleeve 5043, can limit the moving sleeve 504, improving the stability of the moving sleeve 504 when it moves up and down. The sliding rod 5042 drives the snap-fit ​​plate 5044 to move downward, pressing the limiting plate 603 and causing the limiting plate 603 to move. The movement of the limiting plate 603 drives the moving plate 602 to move. The movement of the moving plate 602 presses the spring 605. The spring 605 deforms, stores and provides elastic potential energy. When the snap-fit ​​plate 5044 moves below the limiting plate 603, the elastic potential energy of the spring 605 drives the limiting plate 603 to reset through the moving plate 602. The limiting plate 603 limits the snap-fit ​​plate 5044, thereby locking the height of the inclined block 507 and preventing the connection between the inclined block 507 and the annular inclined plate 501 from becoming loose.
