Description

Technical Field

[0001] This invention relates to the field of slope construction technology, and more specifically, to a construction equipment and method for steep slopes. Background Technology

[0002] An inverted siphon is a special type of hydraulic facility whose main function is to allow water to flow from one body of water under another or through an obstacle, enabling the water to continue flowing along the original channel. It is commonly used in the construction of infrastructure such as bridges, highways, and railways. When these infrastructures cross rivers or other waterways, inverted siphons are needed to maintain the continuity of the water flow. The working principle of an inverted siphon is based on the siphon effect in fluid mechanics. When water rises to a certain height through one end of the pipe, it overcomes gravity, passes the highest point, and then descends to the other end to flow out. This process requires a certain height difference between the two ends of the pipe, and the entire system must be well-sealed to ensure sufficient pressure for the water to flow through.

[0003] In large-scale water diversion projects, due to the large span of the waterway, it is inevitable to pass through areas with complex terrain, especially when crossing mountainous areas. The waterway needs to be constructed in parallel with tunnels and pipelines. Due to the uneven terrain, many inverted siphon facilities are required. However, due to terrain limitations, not all inverted siphon pipes can be laid underground. Therefore, some inverted siphon pipes need to be laid on the ground. Especially when encountering hillsides, slope protection needs to be constructed on the corresponding hillsides according to the waterway route. The construction of inverted siphon pipes can only proceed after ensuring the safety of the slope.

[0004] The construction of slopes mainly includes squaring and slope protection. The slope protection construction requires anchoring on the slope and the construction of corresponding frame beams and other fixed structures at the anchoring points to form a safe and stable slope structure, which facilitates the construction and installation of the inverted siphon pipe.

[0005] In the planning process of water conservancy projects, to facilitate construction, the most convenient construction routes are selected, preferably those with gentle slopes and small elevation differences. For such slope construction, traditional slope anchoring construction can be used, which involves erecting scaffolding on the construction site and gradually building construction platforms. On these platforms, anchor drilling rigs are used for drilling, grouting, and other anchoring processes. However, in water conservancy project planning, in addition to considering construction convenience, other factors such as terrain and water supply needs must also be considered. Therefore, in actual construction, steep slopes with large elevation differences are inevitable. In such cases, the construction area is large, the environment is harsh, and it is difficult to fully erect scaffolding and construction platforms. In these situations, tower cranes can be used in conjunction with mobile construction platforms. The tower cranes drive the construction platforms close to the slope, and multi-directional traction equipment is used to fix the construction platforms, making construction more convenient. Furthermore, the tower crane system can also be used to hoist inverted siphon pipes after the slope construction is completed, making it more practical.

[0006] Due to the complex geological environment of mountainous areas, the soil on some slopes is relatively soft, making anchor drilling relatively smooth. However, some slopes have complex geological compositions, with hard rock layers easily appearing deep within. In such cases, although a harder drill bit can be used to continue drilling, the tower crane-type construction platform needs to be able to move flexibly during actual drilling. Therefore, it cannot be completely fixed to the slope. The platform mainly relies on its own weight to stay close to the slope. When the drill rod and drill bit encounter difficult drilling conditions, the gradual advancement of the drill rod by the drilling rig is easily affected by the reaction force of the slope soil, resulting in a reaction force that deviates from the slope on the drilling rig and the construction platform. Although this force is not enough to cause a large tilt of the construction platform, it will affect the actual drilling accuracy and thus the actual construction quality. Especially in construction environments with large drilling depths, as the length of the drill rod increases, the drill rod itself is easily affected by the aforementioned unstable factors, causing the drill rod to vibrate or even bend, which can easily lead to stuck drills or other phenomena that affect construction and reduce the construction speed. Summary of the Invention

[0007] The present invention provides a construction equipment and method for high and steep slopes, which aims to solve the problem that the construction platform cannot be completely fixed in the existing tower crane construction of high and steep slopes. When the drill rod and drill bit encounter an environment that is difficult to drill into, a reaction force will be generated on the construction platform that deviates from the slope, thereby affecting the actual construction quality.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a high and steep slope construction equipment, including a tower crane, a construction platform, and a traction machine. The top of the construction platform is connected to the lifting structure of the tower crane via slings. At least two sets of traction machines are provided, with the two sets of traction machines respectively located on both sides of the construction area on the slope. The traction machines are connected to the construction platform via cables. The slings at the top of the construction platform and the cables at the bottom of the construction platform are configured in an oblique tension configuration, which provides a tension force on the construction platform that is close to the slope surface.

[0009] A drilling rig assembly is installed on the construction platform. The drilling rig assembly includes a guide frame, on which the drilling rig body is mounted, and on which the drill rod is mounted.

[0010] The end of the guide frame is also provided with a back brace fixing assembly, which includes a back brace pusher frame. The back brace pusher frame is slidably mounted on the guide frame, and a linear drive for driving the back brace pusher frame to move along the guide frame is fixedly installed on the guide frame. The back brace pusher frame is provided with an expansion structure, which is fixed by expanding and pressing against the inner wall of the anchor hole.

[0011] In a preferred embodiment, the expansion structure includes at least two expansion arc plates, and movable blocks corresponding to the number of expansion arc plates are slidably installed in the inverted support propulsion frame. The expansion arc plates are fixedly connected to the movable blocks, and the expansion arc plates are distributed along the circumferential direction of the outer circumference of the drill rod. The inverted support propulsion frame is provided with a hydraulic drive structure for driving the movable blocks to move.

[0012] In a preferred embodiment, the expansion structure includes an expansion sleeve, which is fixedly installed on the inverted support propulsion frame. The drill rod passes through the expansion sleeve, the outer diameter of the expansion sleeve is larger than the diameter of the drill bit on the drill rod, and the end of the expansion sleeve is tapered. An expansion bladder is fixedly installed on the surface of the expansion sleeve, and a fluid channel is provided in the inner wall of the expansion sleeve. The fluid channel is connected to a fluid pressurization structure, which delivers fluid to the expansion bladder through the fluid channel, causing the expansion bladder to expand and compress the inner wall of the anchor hole. Multiple sets of expansion bladders are spaced apart along the length of the expansion sleeve.

[0013] In a preferred embodiment, a barb bracket is provided in the side wall of the expansion sleeve. The barb bracket is rotatably mounted in the side wall of the expansion sleeve, and one end of the barb bracket away from the conical end of the expansion sleeve extends to the expansion bladder.

[0014] In a preferred embodiment, an arc-shaped piece is provided near the expansion bladder of the barb frame, which is used to fit the expansion bladder. The end of the barb frame away from the expansion bladder extends into the interior of the expansion sleeve and is fixedly installed with a drill rod locator. The drill rod locator is an arc-shaped rod structure and has a circular cross-sectional shape.

[0015] In a preferred embodiment, a static pressure assembly is provided at the end of the guide frame. The static pressure assembly includes an annular sandbag and a counterweight plate. The annular sandbag has an annular bag structure and is fitted around the expansion support structure. The counterweight plate has an annular structure and is fitted around the expansion support structure. The counterweight plate is located on the side of the annular sandbag away from the slope.

[0016] In a preferred embodiment, the static pressure assembly further includes a support frame, which is fixedly installed at the end of the guide frame. Multiple positioning pins are slidably installed on the support frame and arranged around the expansion structure. An annular sandbag is arranged inside the multiple positioning pins. A counterweight plate is slidably engaged with the positioning pins. A traction structure is also provided on the counterweight plate.

[0017] In a preferred embodiment, a platform positioning component is provided on the construction platform. The platform positioning component includes a locator, which is installed on the construction platform via a telescopic controller. The telescopic controller is used to control the movement of the locator. The platform positioning component is provided with at least two sets, one above and one below, and two sets, one on the left and one on the right, in each set.

[0018] In a preferred embodiment, the drilling rig assembly is installed in the construction platform via a tilting support platform. The tilting support platform includes a fixed frame and a tilting frame. The tilting frame is rotatably mounted on the fixed frame, and a tilting controller is provided between the tilting frame and the fixed frame. The tilting controller is used to drive the tilting frame to tilt. A guide frame is mounted on the tilting frame.

[0019] A method for constructing steep slopes includes the following steps:

[0020] Step 1: Erect a tower crane at the appropriate location on the top of the slope according to the construction requirements;

[0021] Step 2: Use a tower crane and squaring machinery to square and level the slope to create the slope conditions required for construction.

[0022] Step 3: Assemble the construction platform with the tower crane, and set up a traction machine at the corresponding position to pull the construction platform from both sides, and control the construction platform to move to the corresponding construction position through the tower crane;

[0023] Step 4: Start the drilling rig assembly to perform preliminary drilling. Once the required length for the expansion structure has been reached, stop drilling.

[0024] Step 5: Control the inverted support propulsion frame to move forward, so that the expansion support structure is inserted into the drilled hole, and control the expansion support structure to expand, contact the inner wall of the hole and form a tight pressure;

[0025] Step 6: Start the drilling rig assembly to continue drilling until a suitable anchor hole is drilled. Then, insert the anchor rod, perform grouting, and complete the anchoring operation.

[0026] Step 7: Adjust the construction platform to the next construction area until all anchor points are completed.

[0027] The beneficial effects of this invention are as follows: This invention inserts the expansion structure into the drilled anchor hole through the inverted propulsion frame, so that the expansion structure is fixed by expanding and pressing against the inner wall of the anchor hole, thereby enabling the drilling rig assembly to directly connect with the slope a. This effectively provides relative fixing force to the guide frame, thereby counteracting the reverse thrust of the drill rod, further improving drilling efficiency, avoiding disturbance to the fixing of the drilling rig assembly by the drill rod, and improving drilling accuracy. At the same time, since the inverted propulsion frame and the expansion structure are directly connected to the guide frame, the drilling of the drill rod is more stable and precise, and will not cause bending deformation of the drill rod, effectively avoiding accidents such as stuck drill, and improving construction efficiency.

[0041] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0042] Refer to the instruction manual appendix Figures 1 to 11 A high and steep slope construction equipment includes a tower crane 1, a construction platform 2, and a traction machine 3 (e.g., a winch). The tower crane 1 is set at the top of the slope a according to the design requirements and corresponds to the construction area of ​​the inverted siphon pipe laying area. If the slope a is high, multiple sets of tower cranes 1 can be set at other locations on the slope a for coordinated construction. As the tower crane 1 is a commonly used technology in the engineering field, it will not be explained in detail in this embodiment. At the same time, this embodiment uses a suspended basket structure as the construction platform 2 for explanation (other frame structures can also be used).

[0043] The top of construction platform 2 is connected to the lifting structure of tower crane 1 via slings. The position and height of construction platform 2 are controlled by the boom, trolley, and luffing mechanism of tower crane 1. To improve the stability of construction platform 2 during operation, please refer to the attached instruction manual. Figure 1 At least two sets of traction machines 3 shall be provided, and the two sets of traction machines 3 shall be respectively set on both sides of the construction area on slope a. A concrete platform can be pre-constructed at a designated location on slope a and the traction machines 3 installed thereon. Alternatively, a vehicle with sufficient weight can be placed at the bottom of slope a or on a construction access road to carry the traction machines 3. The traction machines 3 are connected to the construction platform 2 via cables, thereby generating tension in three directions on the construction platform 2, making the construction platform 2 more stable. The slings at the top and bottom of the construction platform 2 shall be inclined towards the surface of slope a. (Refer to the attached instruction manual.) Figure 3That is, the slings at the top of the construction platform 2 and the cables at the bottom of the construction platform 2 are set in an oblique configuration, which makes the slings and cables provide a tension force on the construction platform 2 that is close to the surface of the slope a.

[0044] A drilling rig assembly 4 is installed on the construction platform 2. To facilitate construction, the construction platform 2 can be designed to be larger and can also accommodate other equipment such as anchor bolts and grouting systems. However, this embodiment mainly describes the drilling scheme, so other equipment will not be explained. The drilling rig assembly 4 includes a guide frame 41, on which a drilling rig body 42 is mounted. A drill rod 43 is installed on the drilling rig body 42. A corresponding propulsion system for advancing the drilling rig body 42 is also provided on the guide frame 41. Since the drilling rig assembly 4 used in this embodiment is basically the same as that in the prior art, other common structures will not be described in detail in this embodiment. In existing technologies, drilling rig components 4 are mostly directly fixed to the ground via brackets or supported by scaffolding or other structures. Therefore, the drilling rig component 4 itself possesses sufficient fixing force, and during drilling, the feed of the drill bit 43 can be effectively controlled through the propulsion system. However, in this embodiment, the construction platform 2 is essentially suspended in mid-air, with relatively long slings and cables, exhibiting a degree of mobility. That is, the construction platform 2 does not possess sufficient fixing force like a ground-supported platform. Therefore, to ensure that the drill bit 43 can effectively feed during drilling without providing a reverse thrust to the construction platform 2, refer to the appendix to the instruction manual. Figure 3The end of the guide frame 41 is also provided with a back brace fixing assembly 5. The back brace fixing assembly 5 includes a back brace pusher 51, which is slidably mounted on the guide frame 41. A linear actuator 511 for driving the back brace pusher 51 to move along the guide frame 41 is fixedly installed on the guide frame 41. An expansion structure 52 is provided on the back brace pusher 51. The expansion structure 52 is set corresponding to the anchor hole already drilled by the drill bit on the drill rod 43, and the drill rod 43 passes through the expansion structure 52. During the initial drilling, the linear actuator 511 drives the back brace pusher 51 forward, inserting the expansion structure 52 into the already drilled anchor hole. The expansion structure 52 is fixed by expanding and pressing against the inner wall of the anchor hole, thereby enabling the drilling rig assembly 4 to directly establish a connection with the slope a. When the drill rod When the drill bit 43 encounters a difficult-to-feed soil structure, the drill body 42 is directly fixed to the anchor hole, which can effectively provide relative fixing force to the guide frame 41, thereby offsetting the reverse thrust of the drill rod 43 during drilling. This allows the expansion support structure 52 to form an effective inverted support structure, further improving drilling efficiency and preventing the drill rod 43 from disturbing the fixing of the drill assembly 4, thus improving drilling accuracy. At the same time, since the inverted support propulsion frame 51 and the expansion support structure 52 are directly connected to the guide frame 41, and the feed accuracy of the drill rod 43 is provided by the guide frame 41, under the condition that the expansion support structure 52 can form support, the drilling of the drill rod 43 is more stable and precise, and will not cause bending deformation of the drill rod 43, effectively avoiding the occurrence of unexpected phenomena such as stuck drill, and improving construction efficiency.

[0045] Refer to the instruction manual appendix Figure 4 This embodiment provides a simple expansion support structure 52, which includes at least two expansion support arc plates 521. Correspondingly, movable blocks 512 corresponding to the number of expansion support arc plates 521 are slidably installed in the inverted support push frame 51. The expansion support arc plates 521 and the movable blocks 512 are fixedly connected. The expansion support arc plates 521 are distributed along the circumferential direction of the outer circumference of the drill rod 43. Simply put, the expansion support arc plates 521 can be multiple arc plate structures formed by dividing a circular tube structure sleeved on the outside of the drill rod 43 according to the number of segments. The inverted support push frame 51 is provided with a hydraulic drive structure (e.g., a hydraulic cylinder) for driving the movable blocks 512 to move. When the expansion support arc plates 521 are inserted into the drilled anchor hole, the movable blocks 512 are driven to move by the hydraulic drive structure, causing the expansion support arc plates 521 to expand outward and squeeze the inner wall of the anchor hole to form an inverted support structure.

[0046] In the above embodiments, the direct use of the expanding arc plate 521 for movement and expansion is more suitable for structures with relatively hard soil around the anchor hole. If the soil on the surface of slope a is relatively soft, the expansion and fixing effect is poor. Therefore, this embodiment also provides another expansion structure 52. For details, please refer to the appendix of the specification. Figure 5 and Figure 6The expansion structure 52 includes an expansion sleeve 522, which is fixedly mounted on the inverted support pusher 51. The drill rod 43 passes through the expansion sleeve 522. The outer diameter of the expansion sleeve 522 is larger than the diameter of the drill bit on the drill rod 43, and the end of the expansion sleeve 522 is tapered (the inner diameter of the expansion sleeve 522 can be larger than the diameter of the drill bit to facilitate the drill bit's passage; alternatively, the inner diameter of the expansion sleeve 522 may not be larger than the diameter of the drill bit, but the drill rod needs to be passed through the expansion sleeve 522 before assembly). When the expansion sleeve 522 is inserted into the anchor hole, the outer diameter of the expansion sleeve 522 is larger than... The inner diameter of the anchor hole, through the action of the tapered end, allows the inner wall of the outer part of the anchor hole to be initially compressed and compacted. An expansion bladder 53 is fixedly installed on the surface of the expansion sleeve 522. A fluid channel 523 is provided in the inner wall of the expansion sleeve 522. The fluid channel 523 is connected to a fluid pressurization structure (such as a hydraulic pressurization structure formed by the combination of hydraulic oil and hydraulic pump). The fluid pressurization structure delivers fluid to the expansion bladder 53 through the fluid channel 523, causing the expansion bladder 53 to expand. This allows the expansion bladder 53 to form a secondary expansion and compression on the inner wall of the anchor hole, forming a more stable inverted support structure.

[0047] Furthermore, to improve the inverted support effect of the expansion bladder 53, the expansion bladder 53 is arranged around the expansion sleeve 522, and multiple sets of expansion bladders 53 are spaced apart along the length of the expansion sleeve 522. Thus, after the expansion bladder 53 expands, refer to the appendix of the instruction manual. Figure 6 It can form multi-stage expansion support and improve the strength of the inverted support.

[0048] Further, please refer to the appendix to the instruction manual. Figures 7 to 9 To enhance the support strength of the expansion sleeve 522, this embodiment can further include a barb assembly on the expansion sleeve 522. Specifically, a barb bracket 54 is provided in the side wall of the expansion sleeve 522. The barb bracket 54 is rotatably mounted in the side wall of the expansion sleeve 522. One end of the barb bracket 54, away from the conical end of the expansion sleeve 522, extends to the expansion bladder 53. Furthermore, when the expansion bladder 53 expands, the barb bracket 54 can be pushed outwards to form a barb structure. To further enhance the stability of the expansion sleeve 522 in the anchor hole, when it is necessary to pull out the expansion sleeve 522, the expansion bladder 53 can be controlled to contract first, and then the expansion sleeve 522 can be driven forward. The barb bracket 54 can then contract under the reverse compression of the inner wall of the anchor hole. In addition, an elastic element, such as a torsion spring, can be provided between the barb bracket 54 and the expansion sleeve 522. This elastic element is used to drive the barb bracket 54 to contract inward when the expansion bladder 53 expands, so that the expansion sleeve 522 can be pulled out.

[0049] The barb bracket 54 has an arc-shaped piece 541 near the expansion bladder 53. The arc-shaped piece 541 is used to fit against the expansion bladder 53. The end of the barb bracket 54 away from the expansion bladder 53 extends into the expansion sleeve 522 and is fixedly installed with a drill rod locator 542. The drill rod locator 542 has an arc-shaped rod structure and a circular cross-section. When the expansion bladder 53 expands, the arc-shaped piece 541 can enhance the compression effect of the expansion bladder 53 on the barb bracket 54, thereby compressing the drill rod locator 542 inward and making contact with the surface of the drill rod 43, providing guiding support for the drill rod 43 and further improving the stability of the drill rod 43. At the same time, when the barb bracket 54 flips up and the drill rod locator 542 contacts the drill rod 43, the continued expansion of the expansion bladder 53 will be blocked by the arc-shaped piece 541, resulting in a backward expansion. (Refer to the appendix of the instruction manual.) Figure 7 This allows for a slight compression that moves the expansion sleeve 522 into the anchor hole, thereby improving the back support effect of the expansion sleeve 522.

[0050] It should be noted that the above-mentioned expansion bladder 53 is not limited to use in conjunction with the expansion sleeve 522, but can also be used in conjunction with the expansion arc plate 521.

[0051] In actual construction, situations may arise where the soil on some areas of slope a is relatively loose, especially when drilling with synchronous grouting, or where the soil around the anchor holes is relatively moist due to other reasons. This can easily lead to external soil collapse, thereby affecting the stability of the expansion support structure 52. Therefore, please refer to the appendix of the instruction manual. Figure 10 In this embodiment, a static pressure component 6 is also provided at the end of the guide frame 41. The static pressure component 6 includes an annular sandbag 63 and a counterweight plate 64. The annular sandbag 63 is an annular bag structure and is fitted around the expansion support structure 52. The counterweight plate 64 is an annular structure and is also fitted around the expansion support structure 52. The counterweight plate 64 is located on the side of the annular sandbag 63 away from the slope a. In actual use, the downward pressure of the counterweight plate 64 applies pressure to the annular sandbag 63, so that the annular sandbag 63 can be laid stably on the soil surface around the anchor hole, forming static pressure, reducing the occurrence of collapse, and improving the fixing strength of the expansion support structure 52.

[0052] Furthermore, the static pressure assembly 6 also includes a support frame 61, which is fixedly installed at the end of the guide frame 41. Multiple positioning pins 62 are slidably mounted on the support frame 61, and these positioning pins 62 are arranged around the expansion structure 52. An annular sandbag 63 is disposed inside the multiple positioning pins 62. A counterweight plate 64 is slidably engaged with the positioning pins 62, and a traction structure 65 is also provided on the counterweight plate 64. By adopting the above scheme, before actual drilling, the end of the guide frame 41 can be driven to approach the surface of slope a, allowing each positioning pin 62 to slide freely according to its own condition and contact the surface of slope a, forming a... The positioning support is established. At this time, the annular sandbag 63 naturally adheres to the surface of slope a. The counterweight plate 64 is tilted and moved upward by the traction structure 65 (the traction structure 65 can be a rope structure, manually operated for lifting, or a mechanical structure can be used to control the lifting). Then it is released, causing the counterweight plate 64 to impact downward, forming a tamping effect on the annular sandbag 63. With the help of the annular sandbag 63, the soil on the surface of the slope a to be drilled is compacted, making it less prone to collapse. Moreover, under the positioning support of the positioning nail rod 62 on the annular sandbag 63, the pressure applied by the counterweight plate 64 and the annular sandbag 63 is more stable under static pressure.

[0053] In the above embodiments, to improve the stability of the construction platform 2, a platform positioning component 21 can also be installed on the construction platform 2, as shown in the appendix to the instruction manual. Figure 2 and Figure 3 The platform positioning component 21 includes a locator 211 (such as a pin or pressure plate structure). The locator 211 is installed on the construction platform 2 via a telescopic controller 212. The platform positioning component 21 is provided with at least two sets, one above and one below, and two sets on the left and one on the right in each set. In actual use, the locator 211 is adjusted to extend forward and contact and fix with the surface of the slope a according to the actual situation, thereby adjusting the posture of the construction platform 2 and making the construction platform 2 more stable.

[0054] Further, please refer to the appendix to the instruction manual. Figure 3 The drilling rig assembly 4 is installed in the construction platform 2 via a tilting support platform 22. The tilting support platform 22 includes a fixed frame 221 and a tilting frame 222. The tilting frame 222 is rotatably mounted on the fixed frame 221, and a tilting controller 223 is provided between the tilting frame 222 and the fixed frame 221. The tilting controller 223 is used to drive the tilting frame 222 to tilt. The guide frame 41 is installed on the tilting frame 222, so that the drilling angle of the drilling rig assembly 4 can be freely adjusted during actual use.

[0055] It should be noted that the telescopic controller 212, the tilt controller 223, and the linear actuator 511 used in this embodiment are all commonly used linear drive devices. In order to ensure the driving force, a hydraulic cylinder structure is preferred. At the same time, the tower crane 1, in addition to being used as a hoisting drive for the construction platform 2 during anchoring construction, can also be used simultaneously in other construction processes, such as assisting in squaring in the squaring process, and hoisting the inverted siphon pipe during the subsequent laying of the inverted siphon pipe, etc., thus serving multiple purposes.

[0056] Based on the above implementation methods, please refer to the appendix to the instruction manual. Figure 12 This embodiment also provides a construction method for steep slopes, specifically including the following steps:

[0057] Step 1: Construct tower crane 1 at the appropriate location on the top of slope a according to construction requirements;

[0058] Step 2: Using tower crane 1 and excavation machinery, slope a is excavated (i.e., the earth is excavated) and leveled to form the slope condition required for construction.

[0059] Step 3: Assemble the construction platform 2 with the tower crane 1, and set up the traction machine 3 at the corresponding position to pull the construction platform 2 from both sides, and control the construction platform 2 to move to the corresponding construction position through the tower crane 1;

[0060] Step 4: Start drilling assembly 4 to perform preliminary drilling. After drilling to the required length of the expansion structure 52, pause drilling.

[0061] Step 5: Control the backward propulsion frame 51 to move forward, so that the expansion structure 52 is inserted into the drilled hole.
