Technical Field
[0001] The present application relates to the field of pipe jacking, and in particular to a pipe section, a pipe curtain jacking device and a pipe curtain jacking measurement method. Background Art
[0002] The pipe curtain method is a common construction method for large-section underground excavation tunnels at present. Pipe curtain steel pipes are jacked into the perimeter or arch of the planned underground space, and the pipes are connected to each other by locking joints (generally T-shaped locking joints), which not only increases the support strength of the overall structure but also plays a role in water stoppage.
[0003] The main pipe curtain construction methods include the root pipe drilling method, the pipe jacking method, the horizontal directional spiral jacking method, etc. During the jacking process of pipe curtain steel pipes, especially small-diameter long-distance pipe curtain steel pipes, due to factors such as formation geology and the length of the pipe curtain steel pipes, it is difficult to control the jacking trajectory of the steel pipes, resulting in cracks or deformation and bending at the splicing position of two pipe sections, thus causing the jacking path of the pipe sections to be skewed. Summary of the Invention
[0004] In order to reduce the skewing of pipe sections during jacking, the present application provides a pipe section, a pipe curtain jacking device and a pipe curtain jacking measurement method.
[0005] In a first aspect, the present application provides a pipe section, adopting the following technical solution: A pipe section includes a pipe section body, and a connection assembly for connecting two adjacent pipe section bodies is provided on the pipe section body. The connection assembly includes a left connection block, a right connection block, a positioning block and a reset member. The left connection block is installed on the inner wall of one end of the pipe section body. One end of the right connection block is sleeved on the left connection block, and the other end of the right connection block extends away from the left connection block. The positioning block is installed in the left connection block and is also connected to the right connection block, and the positioning block is located at the end position of the pipe section body. The right connection block is used for being inserted into an adjacent pipe section body and pushing the positioning block to abut against the joint part of the two pipe sections. The reset member is installed in the right connection block and is also connected to the left connection block.
[0006] By adopting the above technical solution, by splicing two pipe section bodies along the same straight line, the right connection block on one pipe section body is inserted into the end of the other pipe section body, so as to facilitate keeping the two pipe section bodies coaxial. At the same time, the right connection block is also used to drive the positioning block to extend out, so that the positioning block abuts against the splicing position of the two pipe section bodies, thus facilitating the welding work in the subsequent process of the two pipe section bodies, facilitating the support of the welding position of the two pipe section bodies, and thus facilitating the reduction of the skewing of the pipe section body during the jacking process.
[0007] In a specific feasible implementation, a limiting ring is further installed on the inner wall of the end of the pipe section away from the left connection block, and the limiting ring is used to abut against the end of the right connection block in the adjacent pipe section.

[0009] In a specific feasible implementation, the reset member includes a reset spring, the reset spring is installed in the right connection block, and the reset spring also abuts against one end of the left connection block located in the right connection block.
[0010] By adopting the above technical solution, when the two pipe section bodies are in a separated state, the right connection block is reset under the action of the reset spring, so as to facilitate keeping the positioning block in a retracted state.
[0011] In a specific feasible implementation, a jacking rod is installed on the positioning block, the jacking rod passes through the side wall of the left connection block and extends to the inner side wall of the right connection block, a jacking groove for the end of the jacking rod to slide is formed on the inner side wall of the right connection block, one end of the jacking groove is located at the end of the right connection block close to the left connection block, and the other end of the jacking groove extends obliquely upward in a direction away from the left connection block.
[0012] By adopting the above technical solution, when the two pipe section bodies are spliced, the positioning block is driven to move in a direction away from the splicing position of the two pipe section bodies through the jacking groove on the right connection block, so as to facilitate the positioning block to support the splicing position of the pipe section bodies.
[0013] In a second aspect, the present application provides a pipe curtain jacking device, adopting the following scheme: A pipe curtain jacking device includes a jacking frame and a jacking mechanism. The jacking mechanism includes a jacking component, a mud discharging component and a clamping component. The jacking component is installed on the jacking frame, the mud discharging component and the clamping component are both installed on the jacking component. The clamping component is used to clamp the end of the pipe section body, and the mud discharging component is used to discharge the muddy water in the pipe section body during jacking.

[0015] In a specific feasible implementation, the jacking assembly includes a support plate, a jacking hydraulic cylinder, a slider, a positioning member, and a linkage member. The support plate and the slider are both slidably mounted on the jacking frame. The jacking hydraulic cylinder is mounted on the support plate, and the piston rod of the jacking hydraulic cylinder is connected to the slider. The support plate is used to push the pipe joint body. Positioning members are mounted on both the support plate and the slider, and the positioning members are used to position the support plate or the slider on the jacking frame. The linkage member connects the positioning member on the support plate and the positioning member on the slider.
[0016] By adopting the above technical solution, the slider is positioned on the jacking frame through the positioning member, and then the support plate is pushed by the jacking hydraulic cylinder to slide in a direction away from the slider, so that the support plate jacks the pipe joint body into the soil layer, thereby facilitating the jacking of the pipe joint body.
[0017] In a specific feasible implementation, the positioning member includes a positioning pin, a positioning spring, an insertion block, and an insertion spring. The positioning pin is mounted on the slider and passes downward through the slider. A positioning hole for inserting the positioning pin is formed on the jacking frame. A baffle is mounted on the side wall of the positioning pin, and the baffle is also connected to the linkage member. The positioning spring is mounted on the positioning pin, and one end of the positioning spring is connected to the baffle, and the other end is connected to the slider. The insertion block is mounted on the support plate. A limiting groove for inserting the insertion block is formed on the side wall of the jacking frame at the position of the positioning hole. The insertion spring is also mounted on the support plate and is also connected to the insertion block.
[0018] By adopting the above technical solution, when it is necessary to position the slider, the positioning pin is inserted into the positioning hole, and at the same time, the insertion block is separated from the jacking frame through the linkage member, so that when the jacking hydraulic cylinder acts, the support plate can be pushed to slide in a direction away from the slider, thereby jacking the pipe joint body. And when it is necessary to further jack the pipe joint body, the linkage member is separated from the insertion block, so that the insertion block is inserted into the limiting groove, thereby limiting the support plate. At the same time, after the piston rod of the jacking hydraulic cylinder extends, it also drives the positioning pin to move upward through the linkage member to be separated from the positioning hole, thereby releasing the positioning of the slider. At this time, the piston rod of the jacking hydraulic cylinder is contracted, so that the slider can move in a direction close to the support plate, and the above actions are repeated to gradually jack the pipe joint body into the soil.
[0019] In a specific feasible implementation scheme, the linkage part includes a left lifting plate, a sleeve, a right push plate and a linkage spring, one end of the left lifting plate is installed on the slider, and the other end of the left lifting plate passes through the side wall of the slider and extends in the direction of the support plate, and a left lifting block is installed at the end of the left lifting plate close to the slider, the cross-section of the left lifting block is a right triangle, and the hypotenuse of the left lifting block is used to contact the bottom wall of the baffle, the sleeve is installed on the side wall of the support plate, and one end of the sleeve is sleeved on the left lifting plate, the right push plate and the linkage spring are both installed on the sleeve, and the linkage spring is also connected to the right push plate, the right push plate is used to contact the slider, and the right push plate is also used to drive the insert block to separate from the limit slot.
[0020] By adopting the above technical solution, during the process of jacking the pipe segment body, when the piston rod of the jacking hydraulic cylinder is extended to the maximum stroke, the left lifting plate moves relative to the slider toward the support plate under the restriction of the sleeve, so that the left lifting plate drives the left lifting block to lift the positioning pin, thereby facilitating the unlocking of the slider. When the jacking hydraulic cylinder retracts the piston rod to move the slider toward the support plate, the positioning pin moves downward under the action of the positioning spring to abut against the jacking frame and slides along the jacking frame until the positioning pin slides to the next positioning hole and is inserted into the positioning hole. At this time, the slider pushes the right push plate, so that the right push plate pushes the push rod to separate the insert block from the limit groove, thereby releasing the positioning of the support plate, thereby facilitating further jacking of the pipe segment body into the soil, thereby facilitating the jacking assembly to continuously jack the pipe segment body into the soil, thereby facilitating improving the jacking efficiency.
[0021] In a specific feasible implementation scheme, the mud discharge assembly includes a driving member and a mud discharge rod, the driving member is installed on the jacking assembly, the mud discharge rod is used to be inserted into the pipe section body, and one end of the mud discharge rod is connected to the driving member, and the other end of the mud discharge rod is used to dig into the soil.

Measurement using a total station in stages: S21. Measurement before jacking: Before the jacking equipment jacks the pipe joint body, the center point of the pipe curtain hole position is lofted on the retaining wall according to the design position. After the mud discharging rod in the mud discharging component of the jacking equipment is installed and debugged in place, the total station is used to accurately position the axis and elevation position of the mud discharging pipe.

[0037] Referring to Figure 2 and Figure 3, six groups of connecting components 2 are arranged inside one end of each pipe joint body 1 except the first pipe joint body 1. The six groups of connecting components 2 inside each pipe joint body 1 are arranged on the inner wall of one end of the pipe joint body 1 along the circumferential direction of the pipe joint. A limiting ring 11 is fixedly installed on the inner wall of the other end of each pipe joint body 1. The connecting component 2 includes a left connecting block 21, a right connecting block 22, a positioning block 23 and a resetting member. One end of the left connecting block 21 is fixedly installed on the inner wall of the end of the pipe joint body 1 away from the limiting ring 11, and the other end of the left connecting block 21 extends towards the end of the pipe joint body 1 away from the limiting ring 11, and there is a gap between the side wall of the end of the left connecting block 21 away from the limiting ring 11 and the inner wall of the pipe joint body 1. One end of the right connecting block 22 is slidably sleeved on the end of the left connecting block 21 away from the limiting ring 11, the other end of the right connecting block 22 extends away from the left connecting block 21, and the end of the right connecting block 22 away from the left connecting block 21 is used for being inserted into the adjacent pipe joint body 1, and the side wall of the right connecting block 22 is in contact with the inner wall of the pipe joint body 1, and the end of the right connecting block 22 away from the left connecting block 21 is used for abutting against the limiting ring 11 inside the adjacent pipe joint body 1.
[0038] Refer to Figure 3 and Figure 4 , the positioning block 23 is slidably installed inside the left connecting block 21, and the sliding path of the positioning block 23 is perpendicular to the axis of the pipe joint body 1, and one end of the positioning block 23 extends towards the direction away from the axis of the pipe joint body 1, and the end of the positioning block 23 away from the axis of the pipe joint body 1 is used for passing through the side wall of the left connecting block 21 and abutting against the inner wall of the end of the pipe joint body 1. Lifting rods 25 are fixedly installed at both ends of the positioning block 23, the ends of the lifting rods 25 extend to the inner wall of the right connecting block 22, and lifting grooves 221 for the lifting rods 25 to slide are formed on the inner wall of the right connecting block 22. One end of the lifting groove 221 is located at the end of the right connecting block 22 close to the left connecting block 21, and the other end extends away from the left connecting block 21 and inclines towards the direction away from the axis of the pipe joint body 1. An avoidance groove for avoiding the positioning block 23 is formed at one end of the right connecting block 22 close to the inner wall of the pipe joint body 1.

In the initial state, the reset spring 24 is in a relaxed state, and at this time, the distance between the limiting ring 11 and the end of the pipe joint body 1 is less than the distance between the end of the right connecting block 22 and the end of the pipe joint body 1.
[0039] The working principle of the embodiment of the present application is as follows: When splicing two pipe body 1s, by keeping the two pipe body 1s coaxial and inserting the right connection block 22 on one of the pipe body 1s into the other pipe body 1, the right connection block 22 slides along the inner wall of the pipe body 1 until it abuts against the limit ring 11 and stops moving under the action of the limit ring 11. When the right connection block 22 starts to abut against the limit ring 11 until it stops moving, the ends of the two pipe body 1s abut against each other, thus realizing the splicing. At the same time, the right connection block 22 moves towards the left connection block 21 under the action of the limit ring 11, so that the right connection block 22 drives the jacking groove 221 to move towards the left connection block 21, thereby lifting the positioning block 23, and the end of the jacking block sequentially passes through the side walls of the left connection block 21 and the right connection block 22 and abuts at the splicing position of the two pipe body 1s, which is convenient for keeping the two pipe body 1s coaxial, reducing the misalignment between the two pipe body 1s, facilitating subsequent welding of the splicing position of the two pipe body 1s, splicing the two pipe body 1s into a longer pipe section, maintaining the coaxiality between the two pipe body 1s through the positioning block 23, protecting the welding position of the two pipe body 1s, reducing cracks at the welding position, and facilitating keeping a straight line when jacking the pipe body 1 and reducing deviation.

The column 4131 is also located in the chute 4182, and the column 4131 is used to abut against the inner wall of the end of the chute 4182 away from the left lifting block 4181.
[0045] Referring to Figure 6 and Figure 7, the sleeve 419 is fixedly installed on the side wall of the support plate 411 near the slider 413 along the axial direction of the guide rail 31, and one end of the sleeve 419 extends towards the slider 413 and is sleeved on one end of the left lifting plate 418 away from the slider 413, and the sleeve 419 is slidably connected to the left lifting plate 418. The right push plate 4110 is slidably installed on one end of the left lifting plate 418 near the sleeve 419 along the axial direction of the guide rail 31.

Then, the piston rod of the jacking hydraulic cylinder 412 extends, so that the jacking hydraulic cylinder 412 pushes the support plate 411 to move away from the slider 413 to the next limiting groove 312, so that the support plate 411 pushes the pipe joint body 1 into the soil layer, thus realizing the jacking of the pipe joint body 1. During the process of the support plate 411 moving to the new limiting groove 312, the left lifting plate 418 gradually slides out of the sleeve 419, and the slider 413 gradually moves away from the support plate 411, so that the slider 413 is separated from the right push plate 4110. Thus, the right push plate 4110 moves away from the support plate 411 under the action of the linkage spring 4130, driving the push rod 4120 to be gradually separated from the insert block 416, so that the insert block 416 is reset under the action of the insertion spring 417, and the end of the insert block 416 abuts against the side wall of the guide rail 31. And as the support plate 411 gradually slides towards the limiting groove 312, and as the piston rod of the jacking hydraulic cylinder 412 gradually extends to the limit position, the left lifting plate 418 gradually extends from the sleeve 419 to the maximum distance and is pulled by the sleeve 419, so that the left lifting plate 418 drives the left lifting block 4181 to move towards the slider 413, so that the inclined side on the left lifting block 4181 abuts against the baffle plate 4141 and pushes the baffle plate 4141 upward and compresses the positioning spring 415, separating the positioning pin 414 from the positioning hole 311, thus releasing the positioning of the slider 413. At the same time, the insert block 416 also slides to the limiting groove 312 with the support plate 411 and is inserted into the limiting groove 312, so that the support plate 411 is positioned at the current position.
[0048] Refer to Figure 6 and Figure 7, then the piston rod is driven to contract by the jacking hydraulic cylinder 412, so that the piston rod drives the slider 413 to move towards the support plate 411, shortening the distance between the slider 413 and the support plate 411. When the slider 413 slides to a positioning hole 311 near the support plate 411, the left lifting plate 418 is inserted to the deepest part in the sleeve 419. Then, as the slider 413 continues to move, the slider 413 drives the positioning pin 414 to move relative to the left lifting block 4181 in a direction away from the left lifting block 4181, causing the left lifting block 4181 to gradually separate from the baffle 4141 on the positioning pin 414, so that the positioning pin 414 moves downward under the drive of the positioning spring 415, until the lower end of the positioning pin 414 abuts against the top wall of the guide rail 31. Until the slider 413 slides under the drive of the jacking hydraulic cylinder 412 to align the positioning pin 414 with the positioning hole 311, so that the positioning pin 414 is inserted into the positioning hole 311 under the action of the positioning spring 415, thereby positioning the slider 413 at the current position. At the same time, the slider 413 abuts against the right push plate 4110, so that the right push plate 4110 drives the push rod 4120 to be inserted into the insert block 416, and separates the insert block 416 from the guide rail 31 again, thereby releasing the limit of the support plate 411. Then repeat the above steps to further realize the action of jacking the pipe joint body 1 into the soil layer.
[0049] Refer to Figure 6 and Figure 7 , when the jacking assembly 41 moves to the position closest to the soil layer and the piston rod of the jacking hydraulic cylinder 412 is in a contracted state, the insert block 416 on the support plate 411 separates from the limit groove 312, then the positioning pin 414 is lifted upward to release the limit of the slider 413 by the positioning pin 414, and then the slider 413 and the support plate 411 are pushed in the direction away from the soil layer to the initial position, so as to facilitate continuous jacking of the pipe joint body 1.

The driving shaft 423 is rotatably installed on the speed reducer 422, and the driving shaft 423 is connected to the output end of the speed reducer 422. The driving shaft 423 is parallel to the axis of the guide rail 31, and one end of the driving shaft 423 passes through the side wall of the support plate 411 and extends away from the slider 413. The mud discharging rod 424 is used for being inserted into the pipe section, and one end of the mud discharging rod 424 is sleeved on the end of the driving shaft 423 away from the slider 413. The other end of the mud discharging rod 424 is used for abutting against the side wall of the soil layer and for tunneling into the soil layer. A spiral blade 425 is also fixedly installed on the peripheral side wall of the mud discharging rod 424. The spiral blade 425 is used for conveying the silt during the tunneling process of the mud discharging rod 424 towards the support plate 411, and a mud discharging hole for discharging the silt is formed on the support plate 411. The operations of the speed reducer 422 and the tunneling of the mud discharging rod 424 are prior arts in the field and will not be elaborated here.
[0051] Referring to Figure 8 , the clamping assembly 43 includes a clamping collar 431.

[0052] The working principle of the embodiment of the present application is as follows: By sleeving one end of the mud discharging pipe on the rotating shaft, then sleeving one end of the pipe section body 1 on the clamping collar 431 on the support plate 411, and then gradually pushing the pipe section body 1 into the soil through the jacking assembly 41. After one pipe section body 1 is pushed into a suitable position, the jacking assembly 41 is reset, and then a new pipe section body 1 is spliced to the original pipe section. The connecting assembly 2 is used to position the connecting part of the two pipe section bodies 1 and weld the two pipe section bodies 1. At the same time, a new mud discharging pipe is spliced to the original mud discharging pipe to facilitate continuous tunneling into the soil, so as to facilitate the jacking of the pipe section.
