Description

Technical Field

[0001] The present application relates to the field of pipe jacking machines, and in particular to a pipe jacking machine and a construction process thereof under trenchless through-hole and blind-hole conditions. Background Art

[0002] The traditional construction techniques of pipe jacking machines include the following: 1. A single oil cylinder drives the pipe jacking into the soil, and manual entry into the pipe is required to clean up the debris, which is extremely unsafe. 2. The power machine head is used for jacking, and the machine head moves with a spiral drill rod in front of it. The debris is discharged in the receiving pit. When encountering a clay layer, it is easy to block the power machine head and blind hole construction is impossible. 3. The pipe is laid using mud water balance or earth pressure balance jacking. In the laying of small diameter pipes, the precision control is poor. 4. The pipe is pushed into the pipe by a pipe jacking machine, and then a spiral drill rod is used to assist in excavation.

[0003] After the pipe jacking machine in item 4 pushes the pipe into the formation, the jacking cylinder needs to drive the movable frame to withdraw before the next guide drill rod or spiral drill rod is pushed in; if the guide drill rod or spiral drill rod needs to be pulled out from the formation, the jacking cylinder needs to drive the movable frame to slide forward and pull out the next guide drill rod or spiral drill rod after the guide drill rod or spiral drill rod is pulled out. In actual construction, affected by the resistance during the jacking process and in order to avoid damage to the guide drill rod or spiral drill rod during the jacking process or the pulling process, the sliding speed of the movable frame is set within a certain range, but this results in the movable frame withdrawing after pushing the guide drill rod or spiral drill rod and sliding forward after pulling out the guide drill rod or spiral drill rod too slowly, making the operation time interval of the pipe jacking machine too long, which seriously reduces the construction efficiency of the pipe jacking machine. Summary of the invention

[0004] In order to shorten the operation time interval of a pipe jacking machine and improve the construction efficiency of the pipe jacking machine, the present application provides a pipe jacking machine and a construction process thereof under non-excavation through-hole and blind-hole conditions.

[0005] In the first aspect, the present application provides a pipe jacking machine, which adopts the following technical solution:

[0006] A pipe jacking machine comprises a frame, a movable frame is slidably connected to the frame, a jacking cylinder is arranged on the movable frame for driving the movable frame to slide, a rotating power part is arranged on the movable frame, a guide drill rod or a spiral drill rod is installed on the rotating power part, a hole wall steel pipe is sleeved on the spiral drill rod, the rotating power part is used to drive the guide drill rod or the spiral drill rod to rotate, and a driving component for driving the movable frame to slide is also arranged on the frame, and the speed at which the driving component drives the movable frame to slide is greater than the speed at which the jacking cylinder drives the movable frame to slide.

[0007] By adopting the above technical scheme, during the jacking operation, the guide drill rod or spiral drill rod is installed on the rotating power part, and the jacking cylinder drives the movable frame to gradually slide forward on the frame, and drives the rotating power part to move forward with the movable frame, so that the guide drill rod or spiral drill rod is slowly pushed into the formation. At this time, the driving component drives the movable frame to slide backward on the frame. Since the speed at which the driving component drives the movable frame to slide is greater than the speed at which the jacking cylinder drives the movable frame to slide, the movable frame can be quickly reset, which is convenient for jacking the next guide drill rod or spiral drill rod. When it is necessary to jack the guide drill rod or When the spiral drill rod is retracted, the driving assembly drives the movable frame to slide forward quickly on the frame, so that the rotating power part is connected to the guide drill rod or spiral drill rod in the formation, and then the jacking cylinder drives the movable frame to gradually slide backward on the frame, and slowly pulls the guide drill rod or spiral drill rod out of the formation, so that the movable frame can be slowly pushed in and quickly retracted during the jacking of the guide drill rod or spiral drill rod, and at the same time, the movable frame can be slowly retracted and quickly pushed in during the retraction of the guide drill rod or spiral drill rod, which effectively shortens the operating time interval of the pipe jacking machine and improves the construction efficiency of the pipe jacking machine.

[0008] Optionally, the driving assembly includes a chain, a sprocket and a first driving member, two sprockets are provided, and the two sprockets are respectively rotatable along the sliding direction of the movable frame and connected to two ends of the frame, the chain is provided between the two sprockets and used in conjunction with the sprockets, the chain is fixedly connected to the movable frame, the first driving member is connected to one of the sprockets, and is used to drive the sprocket connected thereto to rotate.

[0009] By adopting the above technical solution, since leakage and the like often exist in the hydraulic transmission process, and there is a large flow resistance in the flow process of the liquid in the hydraulic transmission process, more energy loss is generated in the hydraulic process, resulting in a low efficiency of the hydraulic transmission, generally between 0.6-0.7. The efficiency of the mechanical transmission system is much greater than the efficiency of the hydraulic transmission system, wherein the average efficiency of the chain transmission is 0.96. The first driving member drives the sprocket connected to it to rotate, and the chain is transmitted between the two sprockets, so that the chain drives the movable frame to slide on the frame. At this time, the sliding speed of the movable frame driven by the chain on the frame is much greater than the sliding speed of the movable frame driven by the jacking cylinder on the frame, ensuring that the movable frame is quickly retreated during the jacking process of the guide drill rod or the spiral drill rod, and the movable frame is quickly pushed in during the withdrawal of the guide drill rod or the spiral drill rod, thereby improving the construction efficiency of the pipe jacking machine.

[0010] Optionally, the driving assembly includes a winch, a hook and a hanging ring, the winch is connected to the movable frame, the winch includes a drum and a second driving member for driving the drum to rotate, a pull rope is wound around the drum, the hook is fixedly set at one end of the pull rope, two hanging rings are provided, the two hanging rings are respectively fixedly connected to two ends of the frame along the sliding direction of the movable frame, and the hook and the hanging ring are used in combination.

[0011] By adopting the above technical scheme, when the driving component drives the movable frame to slide on the frame, the hook is hung on one of the hanging rings, and then the reel is driven to rotate through the second driving member, and the pull rope is continuously wound on the reel, thereby driving the movable frame to slide on the frame toward the end close to the hook. Since the efficiency of the mechanical transmission system is much greater than the efficiency of the hydraulic transmission system, at this time, the winch drives the sliding speed of the movable frame on the frame much faster than the sliding speed of the movable frame on the frame driven by the jacking cylinder, ensuring that the movable frame can be quickly retreated during the jacking process of the guide drill rod or the spiral drill rod, and the movable frame can be quickly pushed in during the withdrawal of the guide drill rod or the spiral drill rod, thereby improving the construction efficiency of the pipe jacking machine.

[0012] Optionally, the rotating power component is a first hydraulic motor, and a plurality of bearings for bearing axial force and a plurality of bearings for bearing radial force are installed on the output shaft of the first hydraulic motor, and the plurality of bearings for bearing axial force and the plurality of bearings for bearing radial force are staggered.

[0013] By adopting the above technical scheme, during the construction process, the guide drill rod or the spiral drill rod will be installed on the output shaft of the first hydraulic motor for jacking operation. Since the bearing for bearing axial force is installed on the output shaft of the first hydraulic motor, when the output shaft of the first hydraulic motor is subjected to thrust or tension along its axial direction, the output shaft of the first hydraulic motor will transfer the thrust or tension it receives to the bearing for bearing axial force. At this time, the bearing for bearing axial force can bear the thrust or tension it receives, thereby improving the axial load-bearing capacity of the output shaft of the first hydraulic motor; similarly, a bearing for bearing radial force is installed on the output shaft of the first hydraulic motor. When the output shaft of the first hydraulic motor is subjected to an offset force at any angle along its radial direction, the output shaft of the first hydraulic motor will transfer the offset force it receives to the bearing for bearing radial force. At this time, the bearing for bearing radial force can bear the offset force it receives, thereby improving the radial load-bearing capacity of the output shaft of the first hydraulic motor. Separately installing a bearing for bearing axial force and a bearing for bearing radial force on the output shaft of the first hydraulic motor not only enables the output shaft of the first hydraulic motor to have strong load-bearing capacity in both the axial and radial directions, but also enables the axial and radial load-bearing capacity of the output shaft of the first hydraulic motor to be adjusted separately. The staggered arrangement of several bearings for bearing axial force and several bearings for bearing radial force can balance the axial load-bearing capacity and radial load-bearing capacity of the output shaft of the first hydraulic motor, making the axial load-bearing capacity and radial load-bearing capacity of the output shaft of the first hydraulic motor more uniform in the axial direction of the output shaft of the first hydraulic motor, thereby effectively improving the construction performance of the pipe jacking machine, enabling the pipe jacking machine to carry out construction operations on large-diameter pipelines and meet the construction requirements of different formation conditions.

[0014] Optionally, the rotating power member includes a reduction gear box and a plurality of second hydraulic motors installed at the input end of the reduction gear box.

[0015] By adopting the above technical solution, several second hydraulic motors are installed on the reduction box, and several second hydraulic motors provide power to the output end of the reduction box at the same time, thereby effectively improving the load-bearing capacity of the rotating power part. For the same size of load, if a single hydraulic motor is used, it is necessary to ensure that the hydraulic motor has a sufficiently large displacement, and the load of the rotating power part is distributed to several second hydraulic motors through the reduction box. Each second hydraulic motor only needs to have a smaller displacement to meet the overall load-bearing performance of the rotating power part, and the use of a small-displacement second hydraulic motor makes it easy to manufacture the rotating power part, with low cost and better economic benefits.

[0016] Optionally, the rotating power member is slidably connected to the movable frame, the sliding direction of the rotating power member is the same as the sliding direction of the movable frame, and a replacement cylinder for driving the rotating power member to slide is fixedly provided on the rotating power member.

[0017] By adopting the above technical scheme, during the construction process, the replacement cylinder can drive the rotating power part to slide on the movable frame when it is extended and retracted, thereby expanding the movable range of the rotating power part relative to the frame, making the jacking and disassembly process of the guide drill rod and the spiral drill rod more convenient. At the same time, when the guide drill rod or the spiral drill rod is stuck in the formation, the replacement cylinder can drive the rotating power part to slide and drive the guide drill rod or the spiral drill rod to move back and forth in the formation, thereby getting rid of the stuck drill rod phenomenon.

[0018] Optionally, the conveying direction of the auger rod is opposite to the jacking direction.

[0019] By adopting the above technical solution, in the traditional construction method, when the auger rod is drilling forward in the formation, the conveying direction of the auger rod is the same as the jacking direction of the auger rod. In the clay soil, the power head connected to the rear of the auger rod is prone to blockage. The conveying direction of the auger rod is opposite to the jacking direction. When the auger rod is jacking forward in the formation, the slag in the steel pipe of the hole wall will be conveyed backward along the conveying direction of the auger rod, thereby avoiding blockage and jamming during the jacking process of the auger rod, making the jacking operation of the pipe jacking machine smoother.

[0020] Optionally, a positioning frame is slidably connected to the frame, and the sliding direction of the positioning frame is the same as the sliding direction of the movable frame. Both ends of the jacking cylinder in the telescopic direction are respectively fixedly connected to the movable frame and the positioning frame. A latch cylinder is fixedly arranged on the positioning frame. A plurality of latch holes are provided on the frame along the sliding direction of the positioning frame. A latch for being inserted into one of the latch holes is fixedly arranged on the latch cylinder. An indicator groove is provided on the positioning frame, and the length direction of the indicator groove is the same as the telescopic direction of the latch cylinder. An indicator strip fixedly connected to the piston rod of the latch cylinder is slidably connected in the indicator groove, and one end of the indicator strip extends to the outside of the positioning frame.

[0021] By adopting the above technical solution, since the positioning frame is slidably connected to the frame, the positioning frame can be slid to a suitable position on the frame during the construction process, and then the piston rod of the latch cylinder is extended to insert the latch on the latch cylinder into the latch hole on the frame. At this time, the positioning frame and the frame are relatively fixed, and then the piston rod of the jacking cylinder is extended and retracted, and the movable frame is driven to slide on the positioning frame, thereby effectively extending the sliding length of the movable frame on the frame and reducing the size of the frame. Before the driving component drives the movable frame to slide on the frame, the piston rod of the latch cylinder is retracted and the latch is pulled out of the latch hole. At this time, the driving component drives the movable frame and the positioning frame to slide on the frame at the same time, avoiding the latch being located in the latch hole and affecting the sliding process of the movable frame. When the piston rod of the latch cylinder is extended or retracted, the indicator strip will be driven to slide in the indicator groove. Since one end of the indicator strip extends to the outside of the positioning frame, the construction personnel can judge whether the latch is inserted into the latch hole by observing the position of the indicator strip in the indicator groove, thereby making the indicator strip indicate the position of the latch.

[0022] In the second aspect, the present application provides a construction process of a pipe jacking machine under trenchless through-hole conditions, which adopts the following technical solution:

[0023] A construction process of a pipe jacking machine under trenchless through-hole conditions comprises the following steps:

After a guide drill rod is pushed into the formation, the driving assembly drives the movable frame to quickly slide backward on the frame and reset.

At the same time, the rotating power part drives the spiral drill rod to rotate in the formation, so that the spiral drill rod is pushed into the formation, and the slag in the hole protection wall steel pipe is discharged from the end close to the frame through the spiral drill rod. After an auger drill rod and a hole protection wall steel pipe are pushed into the formation, the driving assembly drives the movable frame to slide backward quickly on the frame and reset. At this time, the next spiral drill rod is installed on the rotating power part, and the two adjacent spiral drill rods are abutted, and then the previous operation is repeated until the front end of the hole protection wall steel pipe and spiral drill rod enter the receiving pit;

[0027] S4. Disassembly of the guide drill rod: As the spiral drill rod is pushed forward in the formation, the spiral drill rod pushes the guide drill rod forward and enters the receiving pit.

Disassembly of the auger rod: When the front end of the borehole wall steel pipe and the auger rod enter the receiving pit, the jacking cylinder drives the movable frame to slide slowly backward on the frame, and the rotating power component drives the auger rod to be pulled out of the borehole wall steel pipe, and then the auger rod is removed from the rotating power component, and the driving assembly drives the movable frame to slide quickly forward on the frame, and the rotating power component is connected to the next auger rod, and the previous operation is repeated until all the auger rods are pulled out of the borehole wall steel pipe;

[0029] S6. Pipeline laying: Place the pipeline between the movable frame and the hole wall steel pipe, so that the two ends of the pipeline are respectively in contact with the hole wall steel pipe and the movable frame. The jacking cylinder drives the movable frame to slide forward slowly on the frame, and pushes the pipeline into the formation, and at the same time recovers the pushed hole wall steel pipe in the receiving pit. Then the driving component drives the movable frame to slide backward quickly on the frame and reset. At this time, place the next pipeline between the movable frame and the hole wall steel pipe, and make the two adjacent pipelines abut, and then repeat the previous operation until the front-end pipeline enters the receiving pit; all pipelines are laid.

[0030] By adopting the above technical scheme, when constructing under non-excavation through-hole conditions, the guide drill rod or the spiral drill rod is installed on the rotating power part, and then the jacking operation is gradually carried out through the jacking cylinder, and after jacking, the movable frame is quickly retreated and reset through the driving assembly, and then the next guide drill rod or spiral drill rod is jacked; when the spiral drill rod is disassembled, the spiral drill rod is gradually pulled out through the jacking cylinder, and then the movable frame is quickly advanced through the driving assembly, and then the next spiral drill rod is pulled out, thereby effectively shortening the operating time interval of the pipe jacking machine and improving the construction efficiency of the pipe jacking machine.

[0031] In a third aspect, the present application provides a construction process of a pipe jacking machine under non-trench blind hole conditions, which adopts the following technical solution:

[0032] A construction process of a pipe jacking machine under a non-trench blind hole condition comprises the following steps:

Guide drill rod jacking: The guide drill rod is installed on the rotating power component, and the jacking cylinder drives the movable frame to slowly slide forward on the frame, and the guide drill rod is jacked into the formation. At the same time, the rotating power component drives the guide drill rod to rotate in the formation, so that the guide drill rod is jacked into the formation. After a guide drill rod is jacked into the formation, the driving component drives the movable frame to quickly slide backward on the frame and reset. At this time, the next guide drill rod is installed on the rotating power component, and the previous operation is repeated until the front end of the frontmost guide drill rod is located at the end of the pre-installed pipeline position away from the jacking pit;

[0035] S3, soil discharge by auger drill rod: install the auger drill rod on the rotating power part, and put the pipe on the outside of the auger drill rod so that the pipe abuts against the movable frame, and the jacking cylinder drives the movable frame to slide forward slowly on the frame, and the pipe and the auger drill rod are pushed into the formation, and at the same time, the rotating power part drives the auger drill rod to rotate in the formation, so that the auger drill rod is pushed into the formation, and the debris in the pipeline is discharged from the end close to the frame through the auger drill rod.

DETAILED DESCRIPTION

[0055] The following is combined with Figure 1-11 This application is described in further detail.

[0056] The embodiment of the present application discloses a pipe jacking machine.

[0057] Example 1

[0058] Reference Figure 1 A pipe jacking machine includes a frame 1, on which a movable frame 2 and a positioning frame 3 are arranged, the movable frame 2 is slidably connected to the frame 1, and a jacking cylinder 4 for driving the movable frame 2 to slide on the frame 1 is arranged between the movable frame 2 and the positioning frame 3. A driving assembly 5 for driving the movable frame 2 to slide on the frame 1 is also arranged between the frame 1 and the movable frame 2, and the speed at which the driving assembly 5 drives the movable frame 2 to slide is greater than the speed at which the jacking cylinder 4 drives the movable frame 2 to slide. Figure 1 and Figure 2 A rotating power member 6 is provided on the movable frame 2, a guide drill rod 7 or a spiral drill rod 8 is installed on the rotating power member 6, and a hole wall steel pipe 81 is sleeved on the spiral drill rod 8.

[0059] During the jacking operation, the guide drill rod 7 is first installed on the rotating power part 6, and the jacking cylinder 4 drives the movable frame 2 to slowly slide forward on the frame 1, so that the guide drill rod 7 is jacked forward in the formation. At the same time, the rotating power part 6 drives the guide drill rod 7 to rotate in the formation. When the guide drill rod 7 enters the formation, the driving assembly 5 drives the movable frame 2 to quickly withdraw and reset on the frame 1, and then the next guide drill rod 7 is jacked. When the guide drill rod 7 is jacked, the spiral drill rod 8 is installed on the rotating power part 6, and the hole wall steel pipe 81 is put on the spiral drill rod 8, and then the spiral drill rod 8 is jacked according to the same steps as the guide drill rod 7 jacking method, thereby effectively shortening the time for the movable frame 2 to withdraw during the jacking process of the guide drill rod 7 and the spiral drill rod 8, and improving the construction efficiency of the pipe jacking machine.

[0060] If it is necessary to pull out the guide drill rod 7 or the spiral drill rod 8 in the formation, the jacking cylinder 4 drives the movable frame 2 to slide slowly backward on the frame 1, and pulls the guide drill rod 7 or the spiral drill rod 8 out of the formation, and then the driving component 5 drives the movable frame 2 to slide forward quickly on the frame 1 and connect with the next guide drill rod 7 or spiral drill rod 8 in the formation, and then pulls out the next guide drill rod 7 or spiral drill rod 8, which effectively shortens the time for the movable frame 2 to slide forward during the pulling out process of the guide drill rod 7 and the spiral drill rod 8, thereby improving the construction efficiency of the pipe jacking machine.

[0061] Reference Figure 1 Guide rail beams 11 are fixedly arranged on both sides of the length direction of the top of the frame 1. The guide rail beams 11 are arranged horizontally. The length direction of the guide rail beams 11 is the same as the length direction of the frame 1. The movable frame 2 and the positioning frame 3 are arranged between the two guide rail beams 11 and are slidably connected to the guide rail beams 11. The sliding directions of the movable frame 2 and the positioning frame 3 are the same as the length direction of the guide rail beams 11.

[0062] Reference Figure 2The positioning frame 3 is located on the side of the movable frame 2 away from the jacking direction of the pipe jacking machine. The length direction of the positioning frame 3 is perpendicular to the length direction of the guide rail beam 11. Latch cylinders 31 are fixedly provided at both ends of the positioning frame 3. The telescopic direction of the latch cylinder 31 is the same as the length direction of the positioning frame 3. The piston rods of the two latch cylinders 31 are both facing the side away from each other. A latch 311 is fixedly provided on the piston rod of the latch cylinder 31. A plurality of latch holes 111 are opened along the length direction of the two guide rail beams 11 on the side where the two guide rail beams 11 are close to each other. The latches 311 on the piston rods of the two latch cylinders 31 are respectively inserted into one of the latch holes 111 on the two guide rail beams 11. Two indicator grooves 32 are provided on the positioning frame 3, and the length direction of the indicator grooves 32 is the same as the extension and retraction direction of the latch cylinder 31. Indicator bars 312 are slidably connected in the two indicator grooves 32. The two indicator bars 312 are respectively fixedly connected to the piston rods of the two latch cylinders 31, and one end of the indicator bar 312 away from the latch cylinder 31 extends to the outside of the positioning frame 3.

[0063] When the jacking cylinder 4 drives the movable frame 2 to slide on the frame 1, the positioning frame 3 is first slid to a suitable position on the guide rail beam 11, so that the piston rods of the two latch cylinders 31 are extended, and the two latches 311 are respectively inserted into one of the latch holes 111 on the two guide rail beams 11, and at the same time, the indicator bar 312 is driven to slide in the indicator groove 32, so that the positioning frame 3 and the frame 1 are relatively fixed. At this time, the jacking cylinder 4 drives the movable frame 2 to slide on the frame 1, avoiding the positioning frame 3 from affecting the process of the jacking cylinder 4 driving the movable frame 2 to slide.

[0064] When the driving component 5 drives the movable frame 2 to slide on the frame 1, the piston rods of the two latch cylinders 31 are first contracted, and the two latches 311 are respectively pulled out from the latch holes 111 on the two guide rail beams 11, and the indicator bar 312 is driven to slide in the indicator groove 32. At this time, the driving component 5 drives the movable frame 2 to slide on the frame 1, and drives the jacking cylinder 4 and the positioning frame 3 to slide accordingly, so as to avoid the positioning frame 3 affecting the process of the driving component 5 driving the movable frame 2 to slide.

[0065] Reference Figure 1 and Figure 2The movable frame 2 includes a front top plate 21, a rear vertical plate 22 and a connecting plate 23. The front top plate 21 is located on the side of the rear vertical plate 22 away from the positioning frame 3. The front top plate 21 and the rear vertical plate 22 are both arranged perpendicular to the length direction of the frame 1. Both sides of the front top plate 21 and the rear vertical plate 22 are built on two guide rail beams 11. The front top plate 21 and the rear vertical plate 22 are both slidably connected to the guide rail beam 11, and the sliding directions of the front top plate 21 and the rear vertical plate 22 are in the same direction as the length direction of the guide roller beam. Similarly, a through hole 211 for inserting the guide drill rod 7 or the spiral drill rod 8 is opened on the front top plate 21; the connecting plate 23 and the rotating power member 6 are both located between the front top plate 21 and the rear vertical plate 22, and the rotating power member 6 is located at the center in the width direction of the frame 1. Two connecting plates 23 are provided, and are symmetrically arranged on both sides of the rotating power member 6. The connecting plate 23 is vertically arranged to the front top plate 21, and the two ends of the connecting plate 23 are fixedly connected to the front top plate 21 and the rear vertical plate 22 respectively.

[0066] There are two jacking cylinders 4, which are symmetrically arranged on both sides of the rotating power member 6. The extension and retraction direction of the jacking cylinder 4 is the same as the length direction of the guide rail crossbeam 11. The jacking cylinder 4 is penetrated on the rear baffle 22 and fixedly connected to the front baffle 21. The piston rod of the jacking cylinder 4 is fixedly connected to the positioning frame 3. When the positioning frame 3 is relatively fixed to the frame 1, the piston rod of the jacking cylinder 4 is extended and retracted. At this time, the jacking cylinder 4 will drive the front baffle 21 to approach or move away from the positioning frame 3, and the front baffle 21 drives the connecting plate 23 and the rear baffle 22 to slide on the frame 1, and at the same time drives the rotating power member 6 to push forward or withdraw backward, thereby realizing the driving effect of the jacking cylinder 4 on the sliding process of the movable frame 2.

[0067] Reference Figure 2 A horizontal guide rod 222 is fixedly arranged between the front top plate 21 and the rear vertical plate 22. The length direction of the guide rod 222 is the same as the length direction of the guide rail crossbeam 11. A guide sleeve 2221 is sleeved on the guide rod 222. The guide sleeve 2221 is slidably connected to the guide rod 222. The guide sleeve 2221 is fixedly connected to the rotating power member 6. A replacement oil cylinder 221 is arranged between the rotating power member 6 and the rear vertical plate 22. The extension direction of the replacement oil cylinder 221 is the same as the length direction of the guide rod 222. The replacement oil cylinder 221 is fixedly connected to the rear vertical plate 22, and the piston rod of the replacement oil cylinder 221 is fixedly connected to the rotating power member 6.

[0068] When the guide drill rod 7 or the spiral drill rod 8 gets stuck during the jacking process, the piston rod of the compensation cylinder 221 is extended and retracted, and the compensation cylinder 221 drives the rotating power part 6 to move between the front top plate 21 and the rear vertical plate 22, and drives the guide sleeve 2221 to slide on the guide rod 222, and at the same time drives the guide drill rod 7 or the spiral drill rod 8 to move in the formation, so as to eliminate the stuck drill rod.

[0069] Reference Figure 1The driving assembly 5 includes a chain 51, a sprocket 52 and a first driving member. Two sprockets 52 are provided. The two sprockets 52 are respectively located at the two ends of one of the guide rail beams 11 in the length direction and are rotatably connected to the guide rail beam 11; the chain 51 is arranged between the two sprockets 52 and used in conjunction with the sprockets 52. The chain 51 is fixedly connected to one of the connecting plates 23; the first driving member is used to drive one of the sprockets to rotate. In this embodiment, the first driving member is a stepper motor 53, which is fixedly arranged on the frame 1, and the output shaft 612 of the stepper motor 53 is coaxially arranged and fixedly connected to one of the sprockets 52.

[0070] During the jacking process, after the jacking cylinder 4 slowly pushes the guide drill rod 7 or the spiral drill rod 8 into the formation, the stepper motor 53 drives the sprocket 52 fixed thereto to rotate on the guide rail crossbeam 11, and causes the chain 51 to transmit between the two sprockets 52, while driving the other sprocket 52 to rotate synchronously. At this time, the chain 51 will drive the movable frame 2 to slide backward quickly on the frame 1, and cause the rotating power part 6 to withdraw and reset quickly; during the process of pulling out the guide drill rod 7 or the spiral drill rod 8, after the jacking cylinder 4 slowly pulls the guide drill rod 7 or the spiral drill rod 8 out of the formation, the stepper motor 53 drives the chain 51 to transmit between the two sprockets 52, and drives the movable frame 2 and the rotating power part 6 to slide forward quickly, thereby effectively shortening the operation time interval of the pipe jacking machine and improving the construction efficiency of the pipe jacking machine.

[0071] Reference Figure 2 and Figure 3 The rotating power part 6 is a first hydraulic motor 61, referring to Figure 3 The first hydraulic motor 61 includes a motor body 611, an output shaft 612 is arranged in the motor body 611, the output shaft 612 is rotatably connected to the motor body 611, and the motor body 611 is used to drive the output shaft 612 to rotate in the motor body 611. The output shaft 612 faces the side close to the front top plate 21, and two bearings for bearing axial force and two bearings for bearing radial force are installed on the output shaft 612, and the two bearings for bearing axial force and the two bearings for bearing radial force are staggered. The two bearings for bearing axial force are thrust roller bearings 6121, and the two bearings for bearing radial force are deep groove ball bearings 6122 and cylindrical roller bearings 6123 respectively.

[0072] When in use, the guide drill rod 7 or the spiral drill rod 8 is connected to the output shaft 612, and the motor body 611 drives the output shaft 612 to rotate inside the motor body 611, and drives the guide drill rod 7 or the spiral drill rod 8 to rotate. The two thrust roller bearings 6121 on the output shaft 612 can withstand the axial force exerted on the output shaft 612, and the deep groove ball bearing 6122 and the cylindrical roller bearing 6123 can withstand the radial force exerted on the output shaft 612, thereby effectively improving the axial bearing capacity and radial bearing capacity of the hydraulic motor output shaft 612, improving the construction performance of the pipe jacking machine, enabling the pipe jacking machine to carry out construction operations on large-diameter pipelines, and meeting the construction requirements of different formation conditions.

[0073] Reference Figure 4 , an inner hole 71 is coaxially provided in the guide drill rod 7, and the inner hole 71 passes through both ends of the guide drill rod 7. A guide drill bit 712 is installed at the end of the guide drill rod 7 away from the frame 1, and a light target 711 is installed in the end of the guide drill bit 712 close to the guide drill rod 7. The light target 711 is coaxially arranged with the guide drill rod 7. An electronic laser theodolite 12 with a camera is supported between the side of the positioning frame 3 away from the movable frame 2 and the rear top plate of the frame 1 through a tripod. The electronic laser theodolite 12 is located on the axis of the guide drill rod 7 and is used to receive the laser emitted by the light target 711. A hollow hole 6124 is coaxially provided on the output shaft 612 of the first hydraulic motor 61, and the hollow hole 6124 passes through the output shaft 612 of the first hydraulic motor 61.

A center hole 33 is provided on the positioning frame 3, and the center hole 33 is coaxially arranged with the hollow hole 6124. The laser emitted by the light target 711 successively passes through the inner hole 71, the hollow hole 6124, the through-hole 223 and the center hole 33 and irradiates the electronic laser theodolite 12.

[0074] During construction, the guide drill rod 7 is installed on the output shaft 612 of the first hydraulic motor 61, and the jacking cylinder 4 will push the guide drill rod 7 forward in the formation. During the jacking process, the light target 711 in the guide drill rod 7 will emit a laser, which passes through the inner hole 71, the hollow hole 6124, the perforation hole 223 and the center hole 33 in turn and shines on the electronic laser theodolite 12, and is transmitted to the display according to the signal line of the camera on the electronic laser theodolite 12. The construction personnel can judge whether the drilling route of the guide drill rod 7 is offset by observing the laser offset position displayed on the display, so that the jacking route of the guide drill rod 7 is clearer and more visual, which is convenient for correcting the drilling direction of the guide drill rod 7 and making the drilling trajectory constructed according to the designed route.

[0075] Reference Figure 1, the conveying direction of the auger rod 8 is opposite to the jacking direction. When the jacking cylinder 4 drives the auger rod 8 and the borehole wall steel pipe 81 to push forward in the stratum, the first hydraulic motor 61 drives the auger rod 8 to rotate in the borehole wall steel pipe 81, so that the slag in the borehole wall steel pipe 81 is discharged from the end close to the frame 1 along the conveying direction of the auger rod 8 under the action of the auger rod 8, avoiding the situation in which the power head drives the auger rod to discharge soil in front of the auger in the clay soil and causes the head to be blocked.

[0076] The implementation principle of Example 1 is as follows: during the jacking operation, the guide drill rod 7 or the spiral drill rod 8 is installed on the output shaft 612 of the first hydraulic motor 61, the latch cylinder 31 drives the latch 311 to be inserted into one of the latch holes 111, and then the piston rod of the jacking cylinder 4 is extended to make the movable frame 2 slowly slide forward on the frame 1, and push the guide drill rod 7 or the spiral drill rod 8 forward in the formation. When the guide drill rod 7 or the spiral drill rod 8 enters the formation, the piston rod of the latch cylinder 31 contracts and removes the latch 311 from the latch hole 111, and then the stepping motor 53 drives the chain 51 to transmit between the two sprockets 52, thereby driving the movable frame 2 to quickly withdraw and reset on the frame 1, and then The next guide drill rod 7 or spiral drill rod 8 is pushed in; when the guide drill rod 7 or spiral drill rod 8 in the formation is pulled out, the pushing cylinder 4 drives the movable frame 2 to slide slowly backward on the frame 1, and pulls out the guide drill rod 7 or spiral drill rod 8, then the piston rod of the latch cylinder 31 contracts, so that the latch 311 is taken out from the latch hole 111, and then the stepping motor 53 drives the chain 51 to transmit between the two sprockets 52, thereby driving the movable frame 2 to slide forward quickly on the frame 1 and connect with the next guide drill rod 7 or spiral drill rod 8 in the formation, and then pull out the next guide drill rod 7 or spiral drill rod 8, thereby effectively shortening the operation time interval of the pipe jacking machine and improving the construction efficiency of the pipe jacking machine.

When the front end of the hole protection wall steel pipe 81 and the auger rod 8 enter the receiving pit, the guide drill rod is completely recovered.

[0104] S5. Disassembly of auger rod 8:
