Description

Technical Field

[0001] This invention relates to the field of flood control dike construction technology, specifically to a compaction grouting device and method for flood control dike reinforcement. Background Technology

[0002] Some (earth-rock structure) flood control dikes require reinforcement (e.g., where tunnels penetrate the dike).

[0003] Compaction grouting is a common reinforcement method that requires vertically inserting drill rods into the soil of flood control dikes (after which pressure grouting is performed directly using the drill rods or additional grouting pipes inserted into the drill rods). Multiple drill rods can be vertically joined together to allow for deeper insertion into the soil.

[0004] In traditional technologies, drilling rigs can only insert and pull drill rods, requiring manual installation and unloading (of adjacent drill rods). Some emerging technologies (such as the Chinese patent "A Grouting Device and Method for Road and Bridge Construction," publication number CN118481011A) utilize mechanical equipment to automate the loading and unloading of adjacent drill rods; however, (when inserting drill rods) manual labor is still required to remove, rotate, and move the drill rods originally stored horizontally in the storage chamber to a vertical position above the drilling rig's (insertion and extraction structure), and (when extracting drill rods) manual labor is required to rotate the drill rods vertically extracted from the soil to a horizontal position before inserting them into the storage chamber. Summary of the Invention

[0005] In order to overcome the problem of "low automation in the removal, rotation and storage of drill rods in traditional technologies" in the above-mentioned background technology, the present invention provides a compaction grouting device and a compaction grouting method for reinforcing flood control dikes.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: A compaction grouting device for reinforcing flood control dikes includes a vehicle body with a plug-in module installed at the front end. The plug-in module is used to clamp and vertically plug in and out a drill rod. An upper extension platform is provided on the upper surface of the vehicle body, and a tilting wheel is installed at the front end of the upper extension platform. A first insertion hole is provided in the tilting wheel. The tilting wheel can drive the drill rod inserted into the first insertion hole to switch between a horizontal setting state and a vertical setting state. A storage tank with a rectangular cross-section is provided on the top surface of the upper extension platform, and a discharge chute communicating with the storage tank is provided on one side edge of the front end face of the upper extension platform. The discharge chute points towards the tilting wheel.

[0007] As a further optimization of the present invention, when the drill rod to be inserted extends partially from the storage tank along the lateral direction and is inserted into the first insertion hole, the flipping wheel can rotate to drive the drill rod to be inserted to rotate to a vertical setting state and be located directly above the insertion / removal module; when the drill rod that has been pulled out rises to be located directly above the insertion / removal module and is inserted into the first insertion hole, the flipping wheel can rotate to drive the drill rod that has been pulled out to rotate to a lateral setting state with its middle part placed in the discharge trough and one end placed in the storage tank.

[0008] As a further optimization of the present invention, the bottom edge of the storage tank is provided with an upper protrusion pointing towards the flipping wheel, the top surface of the upper protrusion is provided with a lower extension groove, and a plurality of conveying rollers are provided in the lower extension groove; the conveying rollers can rotate and drive the drill rod to enter and exit the storage tank through the discharge groove; an electromagnet is also provided in the lower extension groove, the electromagnet is used to magnetically attract the drill rod, and to increase the friction between the conveying rollers and the drill rod pressed against their upper surfaces; a first gap is provided between the top surface of the electromagnet and the bottom surface of the drill rod.

[0009] As a further optimization of the present invention, the conveying roller has an annular groove in the middle of its circumferential surface, and the cross-section of the annular groove is U-shaped or V-shaped and adapted to the drill rod.

[0010] As a further optimization of the present invention, a first horizontal plate is rotatably connected to the top of the outer side wall of the upper protrusion; the first horizontal plate can be rotated to an inclined state, so as to make the drill rod pressed against the top surface of the first horizontal plate roll toward or away from the conveying roller.

[0011] As a further optimization of the present invention, a slanted push rod is inserted into the side wall of the upper extension platform. When the slanted push rod extends, it is used to push the drill rod to roll from above the conveying roller to above the first horizontal plate.

[0012] As a further optimization of the present invention, the bottom end of the lower extension groove is connected to the lower part of the storage tank through a guide inclined hole, the bottom end of the storage tank is connected to a water storage tank, and the bottom surface of the water storage tank is covered with a replaceable sponge pad; the bottom end of the side wall of the storage tank is connected to a wastewater pipe, and a first valve body is installed at the end of the wastewater pipe.

[0013] As a further optimization of the present invention, it also includes a grouting module, which includes a grouting hose. One end of the grouting hose can be detachably connected to the top of the first drill rod at the top via a rotary joint, and the other end is connected to a fluid container via a first liquid pump. The tilting wheel includes a support part and a clamping part rotatably connected to the support part. Two clamping parts are provided and are respectively located on both sides of the first insertion hole. The inner sidewall of the clamping part is provided with a first notch for forming the first insertion hole. The clamping part can rotate outward to make way for the vertically moving rotary joint.

[0014] As a further optimization of the present invention, the outer wall of the support portion is provided with a first extension arm, and the outer wall of the clamping portion is provided with a second extension arm. The end of the first extension arm away from the support portion is connected to the second extension arm by a second linear actuator or a first compression spring.

[0015] A compaction grouting method for reinforcing flood control dikes involves using compaction grouting equipment for flood control dike reinforcement. The steps include: S1, removing the drill rod from the storage tank and inserting it downwards into the soil; S2, pulling the drill rod inserted into the soil upwards while simultaneously performing grouting; during the process, the drill rod pulled out of the soil is collected and stored in the storage tank.

[0016] Step S1 further includes the following steps: S11, the end of the first horizontal plate away from the conveying roller is inclined upward, driving the drill rod to press obliquely against the edge of the storage tank near the conveying roller, and the drill rod pressed against the conveying roller is used as the drill rod to be inserted; S12, the tilting wheel rotates until the first insertion hole is coaxial with the discharge trough; S13, the electromagnet begins to magnetically attract the drill rod to be inserted, and at the same time the conveying roller rotates and drives the drill rod to be inserted forward, so that the front end of the drill rod to be inserted passes through the discharge trough and is inserted into the first insertion hole; S14, the electromagnet stops magnetically attracting the drill rod to be inserted, and then the construction personnel install the rotary joint on the rear end of the drill rod to be inserted; then the tilting wheel rotates, so that the drill rod inserted into the first insertion hole rotates to stand above the insertion and extraction module; S15, the drill rod to be inserted is connected to the clamped drill rod, and then the insertion and extraction module inserts the drill rod to be inserted into the soil.

[0017] Step S2 further includes the following steps: S21, the end of the first horizontal plate away from the conveying roller is inclined downward; S22, the tilting wheel rotates until the first insertion hole is erected above the insertion module; then the insertion module pulls the drill rod upward until the pulled-out drill rod is above the insertion module and inserted into the first insertion hole; S23, the pulled-out drill rod is disengaged from the clamped drill rod; then the tilting wheel rotates until the pulled-out drill rod rotates to a horizontal position and is partially placed in the discharge trough and partially pressed against the conveying roller; S24, the electromagnet magnetically attracts the pulled-out drill rod downward, while the conveying roller rotates, driving the pulled-out drill rod to be fully inserted into the storage trough; S25, the electromagnet stops magnetically attracting the pulled-out drill rod; then, the pulled-out drill rod is pushed by the inclined push rod to the top of the first horizontal plate and rolls away from the conveying roller.

[0018] In summary, the present invention has at least one of the following advantages: (1) In this invention, the plug-in module, the flipping wheel, the discharge trough, the storage trough, the conveying roller and the electromagnet are adapted to each other, and can drive the drill rod to be plugged in to partially discharge, fully discharge, rotate, stand above the clamped drill rod, automatically align with the clamped drill rod below, and drive the pulled-out drill rod to rotate, partially enter the storage trough and fully enter the storage trough, thereby realizing the automated operation of drill rod removal, rotation and storage, and the whole has a relatively simple structure and low cost (compared to the robotic arm in the traditional technology).

[0019] (2) When the end of the first horizontal plate away from the conveying roller is inclined upward, it can realize continuous sequential feeding. It is connected with the automatic discharge process and does not require construction personnel to manually control the discharge sequence of the drill rod, thus having a higher degree of automation. When the end of the first horizontal plate away from the conveying roller is inclined downward, it can realize continuous sequential discharge. It is adapted to the automatic receiving process and does not require construction personnel to manually stack, thus having a higher degree of automation.

[0020] (3) Unlike the traditional technology of using the friction force to be transmitted (as driving force) by clamping from both sides (from top and bottom or left and right), the present invention sets both the electromagnet and the conveying roller below the drill rod. The friction force is applied in one direction by using the magnetic attraction and gravity with the same direction, thereby overcoming the resistance friction force on both sides of the drill rod. On the one hand, the drill rod entering the storage cavity from top to bottom will not be obstructed. On the other hand, the function of the drill rod on the first horizontal plate on the side to roll diagonally downward to replenish material will not be obstructed. This ensures the basic function of material conveying and improves the continuity and efficiency of operation.

[0021] (4) When the two clamping parts of the tilting wheel are engaged, the two first notches form the first insertion hole; the clamping parts can rotate outward to make way for the rotary joint (and grouting hose) installed at the end of the drill pipe. The clamping parts and the support parts can be connected by a first compression spring, so that the wedge-shaped rotary joint can forcefully push the clamping parts to drive them to open outward (passively), which has a lower cost. The clamping parts and the support parts can be connected by a second linear actuator, which drives the clamping parts to open outward (actively) to avoid contact and wear with the rotary joint, and can be adapted to the clamping roller to realize the automatic rotation of the drill pipe.

[0022] (5) When the present invention is in transit, the turning wheel rotates to the point where the first insertion hole and the discharge trough are not coaxial, which can stop the drill rod that accidentally extends out of the discharge trough and improve transportation safety.

[0023] (6) The flushing ring can flush the mud and slurry adhering to the outer surface of the drill rod (including the first ring groove), thereby preventing it from jamming the rotating chuck and the overturning wheel, realizing automatic cleaning of the outer side, and improving the reliability of the invention.

[0024] (7) When the drill rod is placed horizontally between the turning wheel and the storage tank, the construction personnel use a water spray gun to rinse the inner cavity of the drill rod: the wastewater with a relatively low concentration is collected in the water storage tank for sedimentation and reuse, while the wastewater with a relatively high concentration flows into the water bucket on the side of the vehicle body in a parabolic shape (in order to avoid dripping onto the plug-in module). (This wastewater with a high concentration will not flow into the storage tank because it has problems such as easily clogging the guide hole, adhering to the conveying roller, and being difficult to clean). Moreover, the construction personnel holding the water spray gun can achieve the two cleanings by standing on the side of the vehicle body without having to walk back and forth between the two ends of the drill rod, which simplifies the operation steps.

[0025] (8) Construction workers can perform the loading and unloading of rotary joints and drill rods by standing (i.e. stepping) on ​​the soil surface, which has high convenience and safety (traditional technology requires the installation of a ladder on the vehicle body, and then construction workers need to climb to the top of the drill rod to perform the loading and unloading of the drill rod).

[0028] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows: Reference Figures 1-2 This embodiment provides a compaction grouting device for reinforcing flood control dikes, including a vehicle body 1, a plug-in module 2, a drill rod 3, a grouting module 4, and a tilting wheel 6. A tracked walking structure is installed at the bottom of the vehicle body 1, used to press against the surface of the soil 5 and drive the vehicle body 1 forward. The plug-in module 2 is fixedly installed at the front end of the vehicle body 1, and is used to clamp and vertically plug and pull the drill rod 3 (including vertically inserting the drill rod 3 into the soil 5, or pulling the drill rod 3 upwards from the soil 5).

[0029] Reference Figures 1-2 Multiple drill rods 3 are provided, and the multiple drill rods 3 are connected vertically in a straight line to insert into the soil 5 at a deeper position, thereby injecting grout (such as concrete mortar) into the deeper position of the soil 5. The drill rods 3 have a hollow rod structure; adjacent drill rods 3 are detachably connected by threads; the bottom end of the drill rod 3 located at the deepest point of the soil 5 is provided with an insertion tip 31 to reduce the resistance of the drill rod 3 during insertion.

[0030] Reference Figures 2-3The drill rod 3 has a grouting hole 32 on its side wall, through which the grout in the inner cavity of the drill rod 3 can flow into the soil 5. This invention can either use an additional grouting pipe (which is paired with the drill rod 3) for grouting operations, or it can use the drill rod 3 directly for grouting operations (i.e., without the need for an additional grouting pipe).

[0031] When additional grouting pipes are installed for compaction grouting: all drill rods 3 have grouting holes 32 on their side walls, and the vertical spacing of adjacent grouting holes 32 is equal (i.e., evenly distributed). The grouting pipes (also provided in multiples and vertically spliced ​​in a straight line) penetrate the inner cavity of all drill rods 3, and only the bottom end of the side wall of the bottom grouting pipe has a grout outlet hole. The construction personnel inject grout into the grouting pipe and simultaneously slowly pull the grouting pipe upward (the grout first penetrates the grout outlet hole and then penetrates the grouting hole 32, and finally seeps into the soil 5), which can achieve compaction grouting from bottom to top, and obtain a complete and continuous cast-in-place pile (after which the drill rods 3 can either be pulled out of the soil 5, or the drill rods 3 can be left in the soil 5 to form a cast-in-place pile together with the hardened grout). Furthermore, a sealing ring is fixedly installed on the middle of the outer wall of the bottommost grouting pipe. The sealing ring is located above the grout outlet and is used to seal between the inner wall of the drill rod 3 and the outer wall of the grouting pipe to prevent pressure loss (grout leakage).

[0032] When directly using drill rod 3 for compaction grouting: a grouting hole 32 is provided on the (secondary) bottom side wall of drill rod 3, which is located at the deepest point (i.e., the bottommost) of the soil 5. The grouting hole 32 is located above the insertion tip 31. The construction personnel connect the grouting module 4 to the top of the top drill rod 3, which allows grout to be directly injected into the borehole cavity. The grout can penetrate the grouting hole 32 and flow into the soil 5. While grouting, the drill rod 3 is slowly pulled up. (After the grout has hardened) a complete and continuous cast-in-place pile can be obtained.

[0033] Reference Figure 2 and Figure 3 The drill rods 3 (except for the lowest drill rod 3) have a first external thread 34 at the bottom and a first internal thread 33 (adapted to the first external thread 34) at the top. The lowest drill rod 3 has a first internal thread 33 (adapted to the first external thread 34) at the top and a plug-in front end at the bottom. Adjacent drill rods 3 are detachably connected via threads, allowing for convenient loading and unloading. Rubber sealing rings can be installed at the threaded connection points to prevent grout leakage. The outer wall of the drill rod 3 can have several first sliding grooves. When the plug-in module 2 is adapted to the first sliding groove position on the outer wall of the drill rod 3, it has higher stability and reliability (i.e., the snap-fit ​​connection makes it easier to apply downward pressure and upward tension, reducing slippage and improving the reliability of the connection function). The vertical spacing between two adjacent first sliding grooves is equal to accommodate the drive stroke of the plug-in module 2.

[0034] Reference Figure 1 , Figure 4 and Figure 5 The front end of the vehicle body 1 is fixedly mounted with a first extension platform 11 (e.g., fixedly connected by bolts / welding); the plug-in module 2 includes a lifting platform 21 disposed above the first extension platform 11, a first linear actuator 23 for driving the vertical movement of the lifting platform 21, and a rotary chuck 22 installed in the lifting platform 21 (the jaws of the rotary chuck 22 can clamp or release the drill rod 3. The rotary chuck 22 can rotate around its own axis to drive the drill rod 3 to rotate: when the drill rod 3 is inserted into the soil 5, its rotation can reduce friction; when the drill rod 3 is pulled out, its rotation can agitate the slurry, preventing the drill rod 3 and the soil 5 from solidifying into a whole after the slurry hardens, making it difficult to pull out the drill rod 3. The rotary chuck 22 is, for example, a manual chuck, an electric chuck, a pneumatic chuck, or a hydraulic chuck, usually a three-jaw or four-jaw structure, which are all conventional existing technologies in the industry and will not be described in detail). When the rotary chuck 22 clamps the outer wall of the drill rod 3 (e.g., the first annular groove 35), the lifting platform 21 drives the rotary chuck 22 to rise and fall, enabling rod extraction and insertion operations. After the lifting platform 21 drives the rotary chuck 22, which is clamped at a certain position of the first annular groove 35, to rise / fall, the rotary chuck 22 releases from that first annular groove 35. Then, the lifting platform 21 drives the rotary chuck 22 to rise / fall and clamp at another position of the first annular groove 35. This process is repeated to achieve continuous rod extraction / insertion operations. The rear end of the lifting platform 21 is connected to the vehicle body 1 via a first linear actuator 23. The first linear actuator 23 is vertically positioned, and its housing is inserted and fixed inside the vehicle body 1 (e.g., by bolts). The output shaft (top) of the first linear actuator 23 is vertically and fixedly connected to the lifting platform 21 (e.g., by bolts). A vertically positioned first guide post 24 (e.g., fixedly connected by bolts) is fixedly installed at the front end of the bottom of the lifting platform 21. A vertically positioned first guide sleeve 25 (e.g., fixedly connected by bolts) is fixedly installed inside the first extension platform 11. The first guide post 24 is adapted to be inserted into the first guide sleeve 25 and vertically slidably connected to reduce the off-center load on the first linear actuator 23 and improve the driving smoothness of the plug-in module 2. There are at least two first guide posts 24 and at least two first guide sleeves 25, which are respectively sleeved on the outer periphery of the two first guide posts 24. The two first guide posts 24 are respectively located at the left and right edges of the front end of the bottom of the lifting platform 21, and the two first guide sleeves 25 are respectively located at the left and right edges of the front end of the first extension platform 11, which is used to further reduce the off-center load and improve the operating stability of the plug-in module 2.

[0035] Reference Figure 4 and Figure 5The lifting platform 21 has a first vertical hole 211 in the middle. The rotating chuck 22 is coaxially arranged with the first vertical hole 211, and the central through hole of the rotating chuck 22 is adapted to communicate with the first vertical hole 211. The first extension platform 11 has a second vertical hole, and a guide sleeve 111 is installed in the second vertical hole. The inner cavity of the guide sleeve 111 is coaxially arranged with the first vertical hole 211. The drill rod 3 penetrates the first vertical hole 211, the rotating chuck 22 and the guide sleeve 111 and is inserted into the soil 5.

[0036] Reference Figure 6 , Figure 7 and Figure 8 The upper surface of the vehicle body 1 is provided with an upper extension platform 12 (e.g., fixed by bolts). A rotatable tilting wheel 6 is mounted at the front end of the upper extension platform 12, and a first insertion hole 60 (in the shape of a straight circular hole) is provided inside the tilting wheel 6. The top surface of the upper extension platform 12 is provided with a rectangular storage groove 121, in which the drill rod 3 can be placed horizontally and stored. A discharge groove 122 communicating with the storage groove 121 is provided on one edge of the front end face of the upper extension platform 12; the discharge groove 122 points towards the tilting wheel 6. The tilting wheel 6 is erected diagonally above the insertion module 2, and the tilting wheel 6 and the first insertion hole 60 can rotate synchronously, so that the first insertion hole 60 is erected above the insertion module 2 and coaxially arranged with the first vertical hole 211 (adapter) (see reference). Figure 7 (for use with a vertically mounted drill rod 3), or to place the first insertion hole 60 horizontally beside the storage tank 121 and coaxially with the discharge tank 122 (adapter) (see reference). Figure 6 (For use with a horizontally positioned drill rod 3). The tilting wheel 6 can drive the drill rod 3, which is inserted into the first insertion hole 60, to switch between a horizontally positioned state and a vertically positioned state (see reference). Figure 8 ).

[0037] The drill rod 3 comprises several parts, including but not limited to the drill rod 3a to be inserted, the drill rod 3b to be clamped, and the drill rod 3c to be pulled out. During the insertion (i.e., drilling) operation: the drill rod 3 partially extending from the discharge chute 122 is the drill rod 3a to be inserted. This invention requires driving it to rotate to a vertical position, directly above the drill rod 3b to be clamped (i.e., directly above the first vertical hole 211 of the insertion / pull-out module 2 and coaxially positioned). Then, the construction worker / equipment rotates the drill rod 3a to be inserted, connecting its bottom end to the top end of the drill rod 3b to be clamped. The insertion / pull-out module 2 can then be used to insert the drill rod 3a into the soil 5. The drill rod 3 clamped by the insertion / pull-out module 2 is the drill rod 3b to be clamped. When performing the rod extraction (i.e. grouting) operation: the drill rod 3 that is pulled out is raised from the soil 5 by the insertion and extraction module 2 and whose bottom height is higher than the top surface of the insertion and extraction module 2 (the lifting platform 21); the present invention needs to drive it to rotate to the horizontal setting state and partially place it in the storage tank 121, so as to facilitate its complete and quick insertion (storage) into the storage tank 121.

[0038] When the drill rod 3a to be inserted extends partially from the storage groove 121 laterally and is inserted into the first insertion hole 60 (refer to...) Figure 6 The rotating wheel 6 can rotate to drive the drill rod 3a to be inserted to rotate to a vertical position and be positioned directly above the insertion / removal module 2 (see reference). Figure 7 (and coaxially set with the first vertical hole 211 / the clamped drill rod 3b); then connect the drill rod 3a to be inserted with the clamped drill rod 3b, and use the insertion and extraction module 2 to vertically insert the drill rod 3a to be inserted into the soil 5.

[0039] When the pulled-out drill rod 3c rises to a position directly above the insertion / removal module 2 and is inserted into the first insertion hole 60 (refer to...) Figure 7 After the drill rod 3c that has been pulled out and the drill rod 3b that has been clamped are separated, the tilting wheel 6 can rotate to drive the drill rod 3c that has been pulled out to a horizontal position with its middle part placed in the discharge trough 122 and one end placed in the storage trough 121 (see reference). Figure 8 Then, the pull-out drill rods 3c are pulled into the storage tank 121 by the conveying rollers 123, and the multiple drill rods 3 are arranged in sequence by the swingable first horizontal plate 126.

[0040] Reference Figure 1 The grouting module 4 includes a grouting hose 41. One end of the grouting hose 41 can be detachably connected to the top of the (first) drill rod 3 via a rotary joint 42 (the rotary joint 42 is, for example, the joint in the national standard "Nomenclature and Terminology of Rotary Joint 42", with standard number GB / T 41069-2021). The other end is connected to a fluid container 44 (e.g., a concrete transport vehicle) via a first liquid pump 43. The fluid container 44 stores water (e.g., clean water) / grout. The first liquid pump 43 is used to pressurize the water / grout into the drill rod 3 (during drilling operations, water can be continuously injected into the drill rod 3, so that water continuously flows out of the grouting hole 32, and it will not be blocked by the soil in the soil 5 during the downward movement of the grouting hole 32. During grouting operations, grout needs to be continuously injected into the drill rod 3). Since the diameter of the rotary joint 42 is typically larger than the outer diameter of the drill rod 3, it will be larger than the diameter of the first insertion hole 60 (because the diameter of the first insertion hole 60 is adapted to the outer diameter of the drill rod 3). Furthermore, due to the obstruction of the grouting hose 41, the drill rod 3 cannot completely penetrate the first insertion hole 60 (see reference). Figure 6 If the drill rod 3a to be inserted needs to be lowered after rotating to the vertical setting position, the rotary joint 42 / grouting hose 41 will be stopped by the tilting wheel 6 and cannot continue to lower; refer to Figure 8 During the lifting process of the removed drill rod 3c by the insertion / removal module 2, the rotary joint 42 / grouting hose 41 at the top of the removed drill rod 3c will be stopped by the tilting wheel 6 and will not be able to rise. To avoid this problem, refer to... Figure 9, Figure 10 and Figure 11 The tilting wheel 6 includes a support part 61 and a clamping part 62 rotatably connected to the support part 61. The support part 61 has a D-shaped cross-section and an outer edge with a superior arc shape. The clamping part 62 has a D-shaped cross-section and an outer edge with a inferior arc shape. There are two clamping parts 62, which are respectively located on both sides of the first insertion hole 60. The inner sidewall of the clamping part 62 is provided with a first notch 621 for forming the first insertion hole 60 (compared to the conventional mechanical claw, the present invention can clamp a longer power arm on the drill rod 3, thus making it easier to drive its rotation). The clamping part 62 can rotate outward to make way for the vertically moving rotary joint 42 (and grouting hose 41), that is, it can allow the rotary joint 42 (and grouting hose 41) to pass through the position of the tilting wheel 6.

[0041] Reference Figure 9 , Figure 10 and Figure 11 The outer wall of the support portion 61 is provided with a first extension arm (e.g., fixedly connected by bolts), and the outer wall of the clamping portion 62 is provided with a second extension arm (e.g., fixedly connected by bolts). The end of the first extension arm away from the support portion 61 is connected to the second extension arm by a second linear actuator 63 or a first compression spring. The flipping wheel 6, the second extension arm, and the second linear actuator 63 / first compression spring form a triangular (or quadrilateral) structure, thereby reducing the probability of jamming.

[0042] When the outer surface of the rotary joint 42 is cylindrical, a solution using a second linear actuator 63 can be employed. This involves the second linear actuator 63 actively pulling the two clamping parts 62 (externally rotating) to open them into a V-shape, allowing the rotary joint 42 (and the grouting hose 41) to pass the position of the tilting wheel 6 without being stopped. This solution eliminates the need for the tilting wheel 6 to contact the rotary joint 42 / grouting hose 41, resulting in lower friction and wear rate. One end of the second linear actuator 63 is rotatably connected to the first extension arm (e.g., via a shaft, bearing, and bearing housing), and the other end is rotatably connected to the second extension arm (e.g., via a shaft, bearing, and bearing housing).

[0043] When the outer surface of the rotary joint 42 is spindle-shaped, a first compression spring can be used. When one end of the rotary joint 42 is inserted into the first insertion hole 60, it can forcefully push the clamping part 62, causing the two clamping parts 62 (externally rotated) to open into a V-shape, allowing the rotary joint 42 (and the grouting hose 41) to pass the position of the tilting wheel 6 without being stopped. This solution has a lower cost and can reduce expenses. To guide the first compression spring, a telescopic rod (comprising multiple sequentially nested pipe sections capable of telescopic movement) can be inserted inside it. One end of the telescopic rod is rotatably connected to the first extension arm (e.g., via a shaft, bearing, and bearing seat), and the other end is rotatably connected to the second extension arm (e.g., via a shaft, bearing, and bearing seat).

[0044] Reference Figure 9 and Figure 10 The inner wall of the clamping block is provided with a second notch 622 adapted to the drill rod 3 and the rotary joint 42. When the clamping block rotates outward, the second notch 622 is used to make way for the rotary joint 42 (and the grouting hose 41). This design allows the clamping part 62 to have a smaller required rotation angle, thereby avoiding jamming. The second extension platform 13 (located away from the outer wall of the vehicle body 1) is equipped with a first motor 68 for driving the rotation of the tilting wheel 6. The housing of the first motor 68 is fixedly connected to the support cross plate 66 (e.g., by bolts). The output shaft of the first motor 68 is connected to the transmission shaft at the center of the tilting wheel 6 (support part) through a first reducer 67. The housing of the first reducer 67 is fixedly connected to the support cross plate 66 (e.g., by bolts). The support cross plate 66 is fixedly connected to the outer wall of the second extension platform 13 (e.g., by bolts). A reinforcing rib is welded to the bottom surface of the support cross plate 66 at the position where it is perpendicular to the outer wall of the second extension platform 13.

[0045] Reference Figure 11 and Figure 12 As the flipping wheel 6 rotates, the second linear actuator 63 / first compression spring can rotate to the underside or front side of the second extension platform 13, thereby avoiding interference. The support part 61 and the clamping part 62 are connected by a first rotating shaft 620, and the first rotating shaft 620 (axial direction) is arranged parallel to the first insertion hole 60 (axial direction).

[0046] Reference Figure 13 and Figure 14 The storage tank 121 has an upper protrusion 1211 (e.g., fixedly connected by bolts / integral fastening) pointing towards the tilting wheel 6 at the bottom edge of the storage tank 121. The top surface of the upper protrusion 1211 has a lower extension groove 1212, within which a conveying roller 123 is provided. Several conveying rollers 123 are arranged in a linear array with equal spacing along the axial direction of the discharge chute 122. The axial direction of the conveying rollers 123 is parallel to the axial direction of the tilting wheel 6. The relative height between the top surface of the conveying rollers 123 and the lower extension groove 1212 is adapted to each other. The outer diameter of the drill rod 3 is adapted to the width of the lower extension groove 1212 and the width of the conveying rollers 123, ensuring that only one drill rod 3 can extend partially from the storage tank 121 through the discharge chute 122 at a time. The conveying rollers 123 can rotate and (using friction) drive the drill rod 3 (along the axis of the drill rod 3) into and out of the storage tank 121 via the discharge chute 122. A second motor 124 for driving the conveyor roller 123 to rotate is installed on the outer wall of the upper extension stage 12. The housing of the second motor 124 is fixedly connected to the outer wall of the upper extension stage 12 (e.g., by bolts). The output shaft of the second motor 124 is inserted into the center hole of the conveyor roller 123 and fixedly connected (e.g., by bolts).

[0047] Reference Figure 13 and Figure 14 An electromagnet 125 is also provided in the lower extension groove 1212. The base of the electromagnet 125 is fixedly connected to the bottom surface of the lower extension groove 1212 by bolts. The electromagnet 125 is set between two adjacent conveying rollers 123. When the electromagnet 125 is energized, it can magnetically attract the drill rod 3 to increase the friction between the conveying roller 123 and the drill rod 3 pressed on its upper surface. (For the drill rod 3 pressed on the conveying roller 123, one side of the drill rod 3 contacts the inner wall of the upper extension platform 12 and generates a resistance friction, and the other side contacts the drill rod 3 on the side and generates a resistance friction. Therefore, the dynamic friction applied by the conveying roller 123 needs to overcome the above two resistance frictions, which is difficult to achieve by the weight of the drill rod 3 itself. Also, the drill rod 3 on the side has a tendency to roll downwards at an angle, which has a tendency to lift the drill rod 3 upwards. Therefore, it is necessary to set up the electromagnet 125 to increase the pressure and friction between the conveying roller 123 and the drill rod 3 located above it.) A first gap is provided between the top surface of the electromagnet 125 and the bottom surface of the drill rod 3 (to avoid contact friction between the two); the height of the first gap is not zero. Another solution is: the drill rod 3 located above the conveying roller 123 bears the oblique pushing force from the first horizontal plate 126 and contacts the inner wall of the upper extension platform 12, generating a resistance friction force (at this time, the drill rod 3 is obliquely stuck in the annular groove on the circumference of the conveying roller 123). Then, the electromagnet 125 magnetically attracts the drill rod 3, so that the drill rod 3 (overcoming the oblique pushing force) is reset and adapted to be stuck in the middle of the annular groove on the circumference of the conveying roller 123. This allows the drill rod 3 to be disengaged from the inner wall of the upper extension platform 12, which is used to accurately align the discharge chute 122 and reduce the wear area.

[0048] In conventional technology, the conveyor rollers 123 are usually arranged in pairs, with the pairs of conveyor rollers 123 clamping the drill rod 3 on the left and right sides or the top and bottom sides. However, this type of arrangement cannot be used in this invention. Figure 14 Taking the shown perspective as an example, for the drill rod 3 pressed against the conveyor roller 123, its left end abuts against several diagonally arranged drill rods 3, making it impossible to install the conveyor roller 123, thus preventing clamping from both sides. (Refer to...) Figure 8When the rotating wheel 6 drives the drill rod 3 to enter the storage cavity from top to bottom, the top opening of the storage cavity (vertical projection of the lower extension groove 1212) cannot be equipped with the conveying roller 123, thus making it impossible to clamp the upper and lower sides. In this invention, the mutually compatible conveying roller 123 and electromagnet 125 are both set below the discharge groove 122, that is, below the drill rod 3, realizing the unidirectional application of dynamic friction. On the one hand, the drill rod 3 entering the storage cavity from top to bottom is not obstructed. On the other hand, the drill rod 3 on the side first horizontal plate 126 still has the tendency to roll downwards (to the conveying roller 123), which can realize the replenishment of the drill rod 3, so as to realize continuous rod insertion operation and improve the continuity and efficiency of operation.

[0049] Reference Figure 14 The conveying roller 123 has an annular groove in the middle of its circumference. The cross-section of the annular groove is U-shaped or V-shaped and is adapted to fit the drill rod 3. The surface of the annular groove is provided with friction texture or rubber layer to increase the friction between it and the drill rod 3.

[0050] Reference Figure 14 and Figure 15 A first horizontal plate 126 (e.g., via a hinge) is rotatably connected to the top of the outer wall of the upper protrusion 1211; the first horizontal plate 126 can rotate to an inclined state to cause the drill rod 3, which is pressed against the top surface of the first horizontal plate 126, to roll toward or away from the feed roller 123. (See reference...) Figure 14 During drilling operations, the first horizontal plate 126 is inclined, and its edge away from the conveying roller 123 is angled upwards. Several drill rods 3 (rolling under their own weight) can then sequentially press obliquely against the edge of the storage tank 121 near the conveying roller 123. After the drill rods 3 on the conveying roller are completely removed from the storage tank 121, the drill rods 3 on the first horizontal plate 126 can roll (under their own weight) towards the conveying roller 123, and the bottommost drill rod 3 can press against the conveying roller 123, thus replenishing the drill rods 3 for continuous operation. (Refer to...) Figure 15 During the drilling operation, the first horizontal plate 126 is inclined, and its edge away from the conveying roller 123 is angled downwards. The drill rod 3 located above the first horizontal plate 126 can roll away from the conveying roller 123 (under its own weight) and sequentially press obliquely against the side edge of the storage tank 121 away from the conveying roller 123. Furthermore, after entering the storage tank 121 from top to bottom and pressing against the conveying roller 123, it is pushed by the inclined push rod 128 and can press against the top of the first horizontal plate 126, subsequently rolling away from the conveying roller 123 until it is obliquely pressed against other drill rods 3. Therefore, this invention enables continuous discharge and return of drill rods 3, has a high degree of automation and operational continuity, and can also achieve sequential arrangement of drill rods 3.

[0051] Reference Figure 16 An inclined push rod 128 is inserted into the side wall of the upper extension platform 12. When the inclined push rod 128 extends, it pushes the drill rod 3 to roll from above the conveyor roller 123 to above the first horizontal plate 126. The extension line of the axis of the inclined push rod 128 points to the center of the circle containing the top edge of the conveyor roller 123. An inclined sleeve 1281 is inserted and fixed inside the side wall of the upper extension platform 12 (e.g., by bolts). The inclined push rod 128 is adapted to be inserted into the inner cavity of the inclined sleeve 1281 and is slidably connected. The inclined push rod 128 and the inclined sleeve 1281 are coaxially arranged. A fourth linear actuator 1282 for driving the extension and retraction of the inclined push rod 128 is installed at the bottom end of the inclined sleeve 1281. The housing of the fourth linear actuator 1282 is fixedly connected to the bottom surface of the inclined sleeve 1281 (e.g., by bolts). The output shaft of the fourth linear actuator 1282 is coaxially arranged with the inclined push rod 128 and fixedly connected (e.g., by bolts). The upper extension platform 12 has an oblique hole in its side wall that is adapted to accommodate the oblique insertion sleeve 1281. A sealing ring is fixedly installed at the top of the inner side wall of the oblique insertion sleeve 1281 (for example, by bolt fixing). The sealing ring is used to achieve a sealed connection between the oblique push rod 128 and the oblique insertion sleeve 1281, thereby preventing water and slurry from flowing in and causing jamming.

[0052] Reference Figure 7 and Figure 17 A flushing ring 7 is installed at the front end of the vehicle body 1. The flushing ring 7 is located below the insert plate module and is coaxially arranged with the first vertical hole 211 of the insert plate module. When the insert module 2 pulls the drill rod 3 upward, the flushing ring 7 can spray flushing water to clean the outer surface of the drill rod 3 (including the surface of the first annular groove 35), avoiding the problem of mud / slurry adhering to the outer surface of the drill rod 3 getting stuck in the rotating chuck 22 / turning wheel 6. One end of the support pipe 71 is fixedly connected to the flushing ring 7 (e.g., by welding) and the other end is fixedly connected to the vehicle body 1 (e.g., by bolts). The flushing ring 7 is provided with a fluid channel 70, which includes an annular main channel and a radial branch channel. One end of the radial branch channel is connected to the annular main channel and the other end points to the center of the flushing ring 7. The bottom surface of the support pipe 71 is provided with a water injection hole. One end of the water injection pipe is connected to the water injection hole through a connecting fitting, and the other end is connected to the water tank through a water pump. The water pump is used to pressurize the water in the water tank into the flushing ring 7, and then spray it on the surface of the drill rod 3. The water pump and water tank are installed inside the vehicle body 1. (Refer to...) Figure 17 and Figure 18 A first sealing ring 72 is installed on the top of the inner outer surface of the flushing ring 7 (e.g., by bolt fixing). The first sealing ring 72 is used to seal the top of the flushing ring 7 and the outer wall of the drill pipe 3, thereby preventing water carrying mud / slurry from splashing upwards into the inner cavity of the guide sleeve 111 (in conjunction with...). Figure 4This avoids the problem of the guide sleeve 111 getting stuck between itself and the drill pipe 3 located inside it. The inner outer surface of the flushing ring 7 is frustoconical, allowing the wastewater generated during flushing to flow downwards.

[0053] Reference Figure 5 When the pulled-out drill rod 3c is separated from the clamped drill rod 3b, the slurry originally located in the inner cavity of the pulled-out drill rod 3c will flow downwards and overflow onto the top surface of the lifting platform 21. Subsequently, the slurry can easily flow into the first vertical hole 211, causing the first vertical hole 211 to jam with the clamped drill rod 3b and the rotating chuck 22 to jam. To avoid such problems, the top surface of the lifting platform 21 is provided with a rubber block 212 (e.g., fixed by bolts). The rubber block 212 has a connecting vertical hole adapted to the first vertical hole 211. This connecting vertical hole is used to laterally compress the outer wall of the drill rod 3, thereby sealing the gap between the drill rod 3 and the first vertical hole 211 and preventing the slurry from flowing in. The top surface of the rubber block 212 is inclined, and the side away from the body is inclined downwards to guide the slurry (flowing out of the inner cavity of the pulled-out drill rod 3c) to the side of the invention, rather than flowing and dripping onto the vehicle body 1.

[0054] Reference Figure 8 and Figure 13 During the rod extraction operation, the tilting wheel 6 drives the top of the extracted drill rod 3c and the rotary joint 42 installed at that position to enter the storage tank 121 from top to bottom. Then, at the moment the worker disconnects the extracted drill rod 3c from the rotary joint 42 (because the rotary joint 42 needs to be installed on the top of the clamped drill rod 3b to achieve continuous rod extraction), slurry will flow out. The amount of slurry is relatively small (because most of the slurry has already flowed out at the moment the extracted drill rod 3c is disconnected from the clamped drill rod 3b), but it will drip onto structures such as the conveying roller 123, the lower groove 1212, the inclined push rod 128, and the electromagnet 125. Therefore, the worker needs to use a handheld water gun (e.g., a high-pressure water gun) to wash these structures and the drill rod 3c. Therefore, in conjunction with... Figure 15The bottom end of the lower extension groove 1212 is connected to the lower part of the storage tank 121 through a guide inclined hole 12111 (the guide inclined hole 12111 is set in the upper protrusion 1211). The bottom end of the storage tank 121 is connected to a water storage tank 1210. The bottom surface of the water storage tank 1210 is covered with a replaceable sponge pad 12100 (the sponge pad 12100 is pressed against the bottom surface of the water storage tank 1210 by stones). The bottom end of the side wall of the storage tank 121 is connected to a wastewater pipe 12101. A first valve body 12102 is installed at the end of the wastewater pipe 12101 (the first valve body 12102 is located at the bottom end of the storage tank 121). Outside the outer wall of the upper extension platform 12), the mixture of water and slurry generated after the water gun is rinsed flows into the water storage tank 1210 along the guide inclined hole 12111 and is stored; after the mixture (i.e. the diluted slurry) settles, the upper clear water can be extracted and reused (it needs to be extracted by an additional water pump instead of being discharged directly by the wastewater pipe 12101), thus achieving the function of water conservation; the lower sediment (mostly concrete particles) is deposited on the sponge pad 12100, and the construction personnel can replace the sponge pad 12100 regularly to remove the sediment. After rinsing the storage tank 121 and the lower extension tank 1212 with a water spray gun, the construction workers insert the nozzle of the water spray gun into one end of the inner cavity of the pulled-out drill rod 3c within the storage tank 121. Water then flows through and rinses the inner cavity of the pulled-out drill rod 3c. The wastewater from the rinsing flows out in a parabolic shape (to avoid dripping onto the insertion / removal module 2) from the end of the pulled-out drill rod 3c away from the vehicle body 1, and then flows into a water bucket 30 (which is pre-placed on the soil surface 5 on the side of the tilting wheel 6 facing away from the vehicle body 1 and is adapted to handle the wastewater flowing from the end of the drill rod 3c). This wastewater can then be filtered and reused. The construction workers only need to stand beside the vehicle body 1 to perform the above two cleaning processes, without having to walk back and forth between the two ends of the pulled-out drill rod 3c, which greatly simplifies the manual operation.

[0055] After cleaning, the extracted drill rod 3c is completely pulled into the storage tank 121 by the conveying roller 123 for storage. Since the drill rod 3 has been cleaned before being stored in the storage tank 121, it will be clean and free of mortar on its surface when the next insertion operation is performed. Therefore, it can directly contact the turning wheel 6 and the insertion module 2 without needing to be cleaned again.

[0056] To achieve waterproofing, dustproofing, and slurry resistance, telescopic sleeves are respectively installed around the outer periphery of the output shaft of the first linear actuator 23, the first guide post 24, the second linear actuator 63, and the third linear actuator 127; protective covers are installed around the outer periphery of the first motor 68 and the first reducer 67; a protective cover is installed around the outer periphery of the second motor 124; and a protective film is installed around the outer periphery of the electromagnet 125. (Refer to...) Figure 15The first horizontal plate 126 is provided with several drainage holes to allow water, slurry or their mixture to flow quickly downward into the water storage tank 1210 instead of accumulating on the first horizontal plate 126.

[0057] Reference Figure 10 A first rubber layer 6211 (e.g., fixedly connected by bolts) is fixedly installed on the inner wall of the first notch 621 to increase the friction between the tilting wheel 6 and the drill rod 3, preventing slippage when tilting the drill rod 3. The pressure between the first rubber layer 6211 and the drill rod 3 is controlled by the second linear actuator 63. For example, after the drill rod 3a to be inserted is connected to the clamped drill rod 3b and is pressed down by the insertion / removal module 2, the second linear actuator 63 can control the clamping part 62 to open, so that the first rubber layer 6211 is disengaged from the drill rod 3, avoiding unnecessary wear.

[0058] The loading and unloading of adjacent drill pipes 3 can be done manually or (semi-)automatically. The loading and unloading of drill pipe 3 directly with the rotary joint 42 can also be done manually or (semi-)automatically. (Refer to...) Figure 2 The outer surface of the drill pipe 3 is provided with a locking surface 36, which is located beside the first internal thread 33 / first external thread 34; see reference Figure 19The rotary joint 42 includes a first cylinder 421 and a second cylinder 422 coaxially arranged and rotatable relative to each other (the two are rotatably connected by a bearing and sealed with sealing graphite and a spring). It is used to prevent the grouting hose 41 from getting tangled on the drill rod 3. The side wall of the first cylinder 421 is connected to and communicates with a connecting inclined pipe 423 (for communication with the grouting hose 41). The inner side wall end of the second cylinder 422 is provided with a second external thread 4211 adapted to the first internal thread 33 (for detachable connection with the drill rod 3). The outer side wall of the second cylinder 422 is provided with a meshing surface 4212. Both the locking surface 36 and the meshing surface 4212 are hexagonal prisms, facilitating engagement with a wrench. Construction personnel can manually disassemble the threads by using two wrenches to clamp the locking surfaces 36 of two adjacent drill rods 3 and rotating them relative to each other. Construction workers use two wrenches to clamp the locking surface 36 of the drill rod 3 and the meshing surface 4212 of the second cylinder 422 respectively, and then rotate them relative to each other to achieve manual disassembly of the threads. Each clamping part 62 is equipped with two clamping rollers. When the first notch 621 of the clamping part 62 is engaged with the outer circumference of the drill rod 3, the circumferential surface of the clamping roller is pressed against the outer wall of the drill rod 3. When the clamping roller rotates, it can drive the drill rod 3 to rotate (the extension of the second linear actuator 63 can increase the friction and pressure between the clamping roller and the drill rod 3; the circumferential surface of the clamping roller is provided with friction texture). After the drill rod 3a to be inserted is vertically positioned above the insertion / removal module 2, the clamping part 62 releases the drill rod 3a to be inserted, causing it to descend and abut against the clamped drill rod 3b. The clamped drill rod 3b is then held and fixed by the insertion / removal module 2 (and cannot rotate). Afterwards, the clamping part 62 re-clamps the drill rod 3a to be inserted and drives its rotation using the clamping rollers, enabling automatic threading of the first internal thread 33 and the first external thread 34 (during thread threading, the drill rod 3a to be inserted is pulled axially relative to the clamping rollers, causing relative axial movement). Similarly, the insertion / removal module 2 clamps and fixes the clamped drill rod 3b, and the clamping part 62 clamps the drill rod 3a to be inserted and drives its rotation using the clamping rollers, enabling automatic thread unwinding (during thread threading, the drill rod 3a to be inserted is pushed axially relative to the clamping rollers, causing relative axial movement). (Refer to...) Figure 6 When the pulled-out drill rod 3c is placed horizontally, the construction personnel can manually clamp the meshing surface 4212 with a wrench, and then the clamping part 62 clamps the pulled-out drill rod 3c and drives it to rotate with the clamping roller, which can realize semi-automatic loading and unloading of the thread.

[0059] Reference Figure 14 and Figure 15 A stop post 1261 (e.g., fixed by bolts) is erected on the upper surface of the first horizontal plate 126 to stop the drill rod 3 pressed against the first horizontal plate 126, thereby preventing the drill rod 3 from hitting the third linear actuator 127 and causing damage / jamming.

[0060] Since this invention needs to be used repeatedly and thus needs to be transported to different construction sites, the journeys are usually bumpy. Therefore, a rope 1262 is used, positioned in an S-shape (viewed from above) above the drill rod 3. The straight portion of the rope 1262 is perpendicular to the drill rod 3 in the storage tank 121. This allows the rope 1262 to stop the drill rod 3 from bouncing upwards, preventing it from popping out from the top opening of the storage tank 121. Hooks for hanging the rope 1262 are bolted to the top of the stop column 1261 and the top of the outer wall of the upper extension platform 12. At this time, the turning wheel 6 rotates until the first insertion hole 60 and the discharge trough 122 are in a non-coaxial state, for example, so that the arc surface of the support part 61 points towards the discharge trough 122. This can stop the drill rod 3 from accidentally extending out of the discharge trough 122, improving transportation safety.

[0061] Reference Figure 20 A sealing block 623 is fixedly provided on the circumferential surface of the clamping part 62 (e.g., through an integral fixed internal connection); the turning wheel 6 can rotate until the sealing block 623 is adapted to be locked in the discharge trough 122 (at this time, both clamping parts 62 are in a snap-fit ​​state, and the turning wheel 6 as a whole is in a disc shape, so that both sealing blocks 623 are adapted to be locked in the discharge trough 122), thereby sealing the discharge trough 122 and preventing the drill rod 3 in the storage tank 121 from passing through the discharge trough 122 and falling off during the turnover and travel of the present invention. Since the sealing block 623 is located on the circumferential surface of the clamping part 62, it does not affect its normal clamping function.

[0062] The drill pipe 3 is made of ferrous metal (e.g., steel) and has a rust-proof layer (e.g., titanium alloy layer) on its surface.

[0063] The first linear actuator 23, the second linear actuator 63, the third linear actuator 127, and the fourth linear actuator 1282 can be electric actuators, pneumatic actuators, hydraulic actuators, or combinations thereof (e.g., electro-hydraulic actuators). The first motor 68 and the second motor 124 are controllable motors (e.g., servo motors or stepper motors). By inputting electrical signals to the controllable motors through an external controller, the speed, number of revolutions per rotation, angle of rotation per rotation, and start / stop timing of the controllable motors can be controlled.

[0064] The present invention also includes an electrical cabinet, which is fixedly installed inside the vehicle body 1 by bolts; the first linear driver 23, the second linear driver 63, the third linear driver 127, the fourth linear driver 1282, the first motor 68, and the second motor 124 are respectively connected to the electrical cabinet by wires and signal lines; the electrical cabinet is connected to an external power supply and an external controller (such as a computer or a PLC programmable logic controller) by wires and signal lines, and the external controller controls the start-stop and other working states of the first linear driver 23, the second linear driver 63, the third linear driver 127, the fourth linear driver 1282, the first motor 68, and the second motor 124 in the present invention through the electrical cabinet.

[0065] A compaction grouting method for reinforcing flood control dikes involves using compaction grouting equipment for flood control dike reinforcement. The steps include: S1, removing the drill rod 3 from the storage tank 121 and inserting it downwards into the soil 5; S2, pulling the drill rod 3 inserted into the soil 5 upwards while simultaneously performing grouting; during the process, the drill rod 3 pulled out of the soil 5 is collected and stored in the storage tank 121.

[0066] Step S1 further includes the following steps: S11, the end of the first horizontal plate 126 away from the conveying roller 123 is inclined upward, and the drill rods 3 are driven to press obliquely against the edge of the storage tank 121 near the conveying roller 123, and the drill rods 3 pressed above the conveying roller 123 serve as the drill rods 3a to be inserted. S12, the flipping wheel 6 rotates until the first insertion hole 60 is coaxially aligned with the discharge trough 122. S13, the electromagnet 125 begins to magnetically attract the drill rods 3a to be inserted, while the conveying roller 123 rotates and drives the drill rods 3a to be inserted forward, so that the front end of the drill rods 3a to be inserted passes through the discharge trough 122 and is inserted into the first insertion hole 60. S14. The electromagnet 125 stops magnetically attracting the drill rod 3a to be inserted. Then, the construction worker installs the rotary joint 42 on the rear end of the drill rod 3a to be inserted (i.e., the end placed in the storage tank 121). Then, the rotating wheel 6 rotates, causing the drill rod 3 inserted in the first insertion hole 60 to rotate and stand upright above the insertion module 2. S15. The drill rod 3a to be inserted is connected to the clamped drill rod 3b. Then, the insertion module 2 inserts the drill rod 3a to be inserted into the soil 5. S16. When the rotary chuck 22 is engaged at the first annular groove 35 at the top of the drill rod 3a to be inserted and is at the bottom dead center, the drill rod 3a to be inserted is disconnected from the rotary joint 42. S17. Repeating steps S11 to S16 allows for continuous operation.

[0067] Step S2 further includes the following steps: S21, the end of the first horizontal plate 126 away from the conveying roller 123 is inclined downward. S22, the flipping wheel 6 rotates until the first insertion hole 60 is erected above the insertion module 2; then the insertion module 2 pulls the drill rod 3 upward until the pulled-out drill rod 3c is above the insertion module 2 and inserted into the first insertion hole 60. S23, the pulled-out drill rod 3c is separated from the clamped drill rod 3b; then the flipping wheel 6 rotates until the pulled-out drill rod 3c rotates to a horizontal position and is partially placed in the discharge trough 122 and partially pressed against the conveying roller 123. S24, the rear end of the pulled-out drill rod 3c (i.e., the end located in the storage tank 121) is separated from the rotary joint 42, then the electromagnet 125 magnetically attracts the pulled-out drill rod 3c downward, while the conveying roller 123 rotates, driving the pulled-out drill rod 3c to be fully inserted into the storage tank 121. S25, the electromagnet 125 stops the pull-out drill rod 3c; then, the pull-out drill rod 3c is pushed by the inclined push rod 128 to the top of the first horizontal plate 126 and rolls away from the conveying roller 123.

[0068] In this invention, the insertion / removal module 2, the flipping wheel 6, the discharge trough 122, the storage trough 121, the conveying roller 123, and the electromagnet 125 are mutually adapted to drive the drill rod 3a to be inserted to partially discharge, fully discharge, rotate, and stand upright above the clamped drill rod 3b, as well as drive the pulled-out drill rod 3c to rotate, partially and fully enter the storage trough 121, thereby realizing the automated operation of taking out, rotating, and storing the drill rod 3. The whole has a relatively simple structure and low cost (compared to the robotic arm in traditional technology).
