Description

Technical Field

[0001] The present invention relates to the technical field of slope construction, and more specifically, to a high and steep slope construction device and a construction method thereof. Background Art

[0002] An inverted siphon is a special water conservancy facility. Its main function is to divert water from one water body through another water body or obstacle so that the water can continue to flow along the original river channel. It is often used in the construction of infrastructure such as bridges, roads, and railways. When these infrastructures cross rivers or other waterways, in order to maintain the continuity of the water flow, it is necessary to build an inverted siphon to maintain the continuity of the water flow. The working principle of the inverted siphon is based on the siphon effect in fluid mechanics. When the water flows through one end of the pipe and rises to a certain height, it will overcome the effect of gravity, pass the highest point, and then fall to the other end and flow out. This process requires a certain height difference in the water levels at both ends of the pipe, and the sealing of the entire system must be good to ensure sufficient pressure for the water to pass through.

[0003] Among them, in large-scale water diversion projects, due to the large span of the waterway, it is inevitable to pass through areas with complex terrain and environment, especially when crossing mountainous areas, the waterway needs to be built in a parallel manner with tunnels and pipelines. Among them, due to the uneven mountain terrain, it is necessary to set up a lot of inverted siphon facilities, and due to terrain restrictions, the inverted siphon pipelines cannot be set up underground. Therefore, some inverted siphon pipelines need to be set up on the ground, especially when encountering hillsides, it is necessary to carry out slope construction on the corresponding hillside according to the waterway route to form slope protection, and then carry out the inverted siphon pipeline construction while ensuring the safety of this section of the slope.

[0004] The construction of the slope mainly includes processes such as excavation construction and slope protection construction. Among them, the slope protection construction requires anchoring construction on the slope, and the construction of corresponding frame beams and other fixed structures in conjunction with the anchoring points, ultimately forming a safe and stable slope structure to facilitate the construction and installation of the inverted siphon pipe.

[0005] In the process of water conservancy project planning, in order to facilitate construction, we will try our best to select a more constructible route, and choose a relatively gentle slope with a small height difference as the construction route. For the above-mentioned type of slope construction, traditional slope anchoring construction can be used, that is, scaffolding is set up at the construction site, and a construction platform is gradually built layer by layer. The anchor drill is used on the construction platform to perform anchoring processes such as drilling and grouting. However, when planning water conservancy projects, in addition to considering the convenience of construction, other factors such as other terrain and water supply demand need to be considered. Therefore, in actual construction, it is inevitable to encounter steeper slopes with higher height differences. At this time, the construction scope is wide and the environment is severe, making it difficult to fully build scaffolding and construction platforms. At this time, you can choose the form of a tower crane, cooperate with a mobile construction platform, drive the construction platform close to the slope with a tower crane, and cooperate with multi-directional pulling equipment to fix the construction platform, thereby making the construction more convenient. The tower crane system can also hoist the inverted siphon pipeline after the slope construction is completed, which is more practical.

[0006] Due to the complex geological environment of the mountains, the soil of some mountain slopes is relatively soft, and the anchor drilling process is relatively smooth. However, the geological composition of some slopes is complex, and hard rock layers are prone to appear in the deep of the slope. At this time, although a drill bit with higher hardness can be selected for continued drilling, the tower crane construction platform needs to ensure the flexible transfer of the construction platform during actual drilling, so the construction platform cannot be completely fixed on the slope. The construction platform mainly relies on its own gravity to stay close to the slope. When the drill rod and drill bit encounter an environment that is difficult to drill, the gradual advancement of the drill rod by the drill rig is easily affected by the reaction of the slope soil layer, resulting in a reaction force that deviates from the slope on the drill rig and the construction platform. Although this force is not enough to cause a large tilt of the construction platform, it will cause the actual drilling accuracy to be affected, and then affect the actual construction quality, especially in a construction environment with a large drilling depth. As the length of the drill rod continues to increase, the drill rod itself is easily affected by the above-mentioned unstable factors, causing the drill rod to vibrate or even bend, which can easily cause drill jamming or other phenomena that affect construction, thereby reducing the construction speed. Summary of the invention

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Refer to the instruction manual 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 (such as a winch), wherein the tower crane 1 is arranged 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 height of the slope a is relatively high, the tower crane 1 can also be provided with multiple groups of tower cranes 1 at other positions on the slope a for coordinated construction. As the tower crane 1 is a common technology in the engineering field, it will not be explained in detail in this embodiment. At the same time, this embodiment uses a hanging basket structure as the construction platform 2 for explanation (other frame structures can also be used).

[0034] The top of the construction platform 2 is connected to the lifting structure of the tower crane 1 through a sling. The position and height of the construction platform 2 are controlled by the jib, trolley and luffing mechanism of the tower crane 1. At the same time, in order to improve the stability of the construction of the construction platform 2, refer to the attached manual. Figure 1 At least two groups of tractors 3 are provided, and the two groups of tractors 3 need to be respectively provided on both sides of the area to be constructed on the slope a. A concrete platform can be built at a designated position on the slope a in advance, and the tractor 3 can be installed. Alternatively, a vehicle with sufficient weight can be provided at the bottom of the slope a or on the construction access road to carry the tractor 3. The tractor 3 is connected to the construction platform 2 through a cable, thereby forming a pulling force in three directions on the construction platform 2, making the construction platform 2 more stable. The slings at the top of the construction platform 2 and the cables at the bottom of the construction platform 2 are both inclined toward the surface of the slope a. Refer to the attached manual for details. 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 arranged in an obliquely pulled configuration, and the obliquely pulled configuration enables the slings and cables to provide a pulling force for the construction platform 2 to approach the surface of the slope a.

[0035] A drilling rig assembly 4 is installed on the construction platform 2. At the same time, in order to facilitate construction, the construction platform 2 can be designed to be larger and equipped with other equipment such as anchor rods and grouting systems. However, this embodiment mainly describes the drilling solution, so other equipment is not explained. The drilling rig assembly 4 includes a guide frame 41, a drilling rig body 42 is provided on the guide frame 41, a drill rod 43 is installed on the drilling rig body 42, and a propulsion system for propelling 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 the drilling rig assembly 4 in the prior art, other general structures are not described in detail in this embodiment. However, since the drilling rig assembly 4 in the prior art is mostly directly connected to the drill rig body 42 through a bracket The drill assembly 4 is fixedly installed on the ground, or fixedly supported by structures such as scaffolding, so the drill assembly 4 itself has sufficient fixing force. When drilling, the drill bit feed of the drill rod 43 can be effectively controlled through the propulsion system. However, in this embodiment, the construction platform 2 is basically in a suspended state, and the slings and cables are relatively long and have a certain degree of mobility, that is, the construction platform 2 does not have sufficient fixing force like the ground support platform. Therefore, in order to ensure that the drill rod 43 can be effectively fed when the drill assembly 4 is drilling, and no reverse thrust is provided to the construction platform 2, refer to Appendix 3 of the specification, and an inverted support fixing assembly 5 is also provided at the end of the guide frame 41. The inverted support fixing assembly 5 includes an inverted support propulsion frame 51, and an inverted support propulsion frame 52. The supporting frame 51 is slidably arranged on the guide frame 41, and a linear driver 511 for driving the inverted supporting frame 51 to move along the guide frame 41 is fixedly installed on the guide frame 41. An expansion structure 52 is arranged on the inverted supporting frame 51, and the expansion structure 52 is arranged corresponding to the anchor hole 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 driver 511 drives the inverted supporting frame 51 to move forward, inserts the expansion structure 52 into the drilled anchor hole, and the expansion structure 52 is fixed by expanding and squeezing the inner wall of the anchor hole, so that the drilling rig assembly 4 can directly establish a connection with the slope a. When the drill bit of the drill rod 43 encounters a soil layer structure that is difficult to feed, the expansion structure 52 is inserted into the anchor hole drilled by the drill bit. The drill body 42 is directly fixed to the anchor hole, which can effectively provide a relative fixing force for the guide frame 41, thereby offsetting the reverse thrust of the drill rod 43, so that the expansion structure 52 forms an effective inverted support structure, further improving the drilling efficiency, avoiding the disturbance of the drill rod 43 on the fixation of the drill assembly 4, and improving the drilling accuracy. At the same time, since the inverted support propulsion frame 51 and the expansion structure 52 are directly connected to the guide frame 41, and the feeding accuracy of the drill rod 43 is provided by the guide frame 41, therefore, under the condition that the expansion structure 52 can form support, the drilling of the drill rod 43 is smoother and more accurate, and will not cause bending and deformation of the drill rod 43, effectively avoiding the occurrence of unexpected phenomena such as drill sticking, and improving construction efficiency.

[0036] Referring to the drilling rig assembly 4 in the attached figure of the specification, this embodiment provides a simple expansion structure 52, that is, the expansion structure 52 includes at least two expansion arc plates 521, and correspondingly, movable blocks 512 corresponding to the number of expansion arc plates 521 are slidably installed in the inverted support propulsion frame 51, and the expansion arc plates 521 are fixedly connected to the movable blocks 512, and the expansion arc plates 521 are distributed along the circumferential direction of the outer circumference of the drill rod 43. In simple terms, the expansion arc plates 521 can be a plurality of circular arc plate structures formed by dividing a circular tube structure sleeved on the outside of the drill rod 43 according to the number, and a hydraulic drive structure (such as a hydraulic cylinder) for driving the movable block 512 to move is provided in the inverted support propulsion frame 51, and then when the expansion arc plate 521 is inserted into the drilled anchor hole part, the movable block 512 is driven to move by the hydraulic drive structure, so that the expansion arc plate 521 expands outward, squeezes the inner wall of the anchor hole, and forms an inverted support structure.

[0037] In the above embodiment, the expansion arc plate 521 is directly used for moving and expanding, which is more suitable for the structure with hard soil around the cat hole. If the soil on the surface of the slope a is soft, the expansion and fixing effect is poor. For this reason, this embodiment also provides another expansion structure 52. For details, refer to the attached manual. Figure 5 and Figure 6 The expansion support structure 52 includes an expansion support sleeve 522, which is fixedly mounted on the inverted support propulsion frame 51, and the drill rod 43 passes through the expansion support sleeve 522. The outer diameter of the expansion support sleeve 522 is larger than the diameter of the drill bit on the drill rod 43, and the end of the expansion support sleeve 522 is set to be conical (wherein, the inner diameter of the expansion support sleeve 522 can be larger than the diameter of the drill bit to facilitate the penetration of the drill bit, and the inner diameter of the expansion support sleeve 522 does not need to be larger than the diameter of the drill bit, but the drill rod needs to be passed through the expansion support sleeve 522 before assembly). When the expansion support sleeve 522 is inserted into the anchor hole, the outer diameter of the expansion support sleeve 522 is larger than the diameter of the drill bit. The inner diameter of the anchor hole is such that the inner wall of the outer part of the anchor hole can be initially compressed and compacted through the action of the tapered end. 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 pressurizing structure (for example, a hydraulic pressurizing structure formed by a combination of hydraulic oil and a hydraulic pump). The fluid pressurizing structure transports fluid to the expansion bladder 53 through the fluid channel 523 to expand the expansion bladder 53, thereby enabling the expansion bladder 53 to form a secondary expansion and extrusion on the inner wall of the anchor hole, thereby forming a more stable inverted support structure.

[0038] Furthermore, in order to improve the inverted support effect of the expansion bladder 53, the expansion bladder 53 is arranged around the expansion sleeve 522, and multiple groups of the expansion bladder 53 are arranged at intervals in the length direction of the expansion sleeve 522. Figure 6 , which can form multi-stage expansion support and improve the strength of inverted support.

[0039] For further information, please refer to the attached manual. Figures 7 to 9 In order to improve the inverted support strength of the expansion sleeve 522, the present embodiment can also be equipped with a barb assembly on the expansion sleeve 522. Specifically, a barb frame 54 is provided in the side wall of the expansion sleeve 522. The barb frame 54 is rotatably installed in the side wall of the expansion sleeve 522. One end of the barb frame 54 away from the conical end of the expansion sleeve 522 extends to the expansion bladder 53. When the expansion bladder 53 expands, the barb frame 54 can be pushed outward to form a barb structure. The stability of the expansion sleeve 522 in the anchor hole is further increased. When the expansion sleeve 522 needs to be pulled out, the expansion bladder 53 can be controlled to shrink first, and then the expansion sleeve 522 can be driven forward, and the barb frame 54 can shrink under the reverse extrusion of the inner wall of the anchor hole. In addition, an elastic member, such as a torsion spring, can be arranged between the barb frame 54 and the expansion sleeve 522. The elastic member is used to drive the barb frame 54 to shrink inward when the expansion bladder 53 expands, so as to facilitate the extraction of the expansion sleeve 522.

[0040] The barb frame 54 is provided with an arc piece 541 at the position close to the expansion bladder 53, and the arc piece 541 is used to fit with the expansion bladder 53, and the end of the barb frame 54 away from the expansion bladder 53 extends to the inside of the expansion sleeve 522, and is fixedly installed with a drill rod positioner 542, which is an arc-shaped rod structure, and the cross-sectional shape of the drill rod positioner 542 is circular. When the expansion bladder 53 is expanded, the expansion bladder 53 can improve the squeezing effect on the barb frame 54 with the help of the arc piece 541, so that the drill rod positioner 542 can be compressed inwardly and contact 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 frame 54 is turned up and the drill rod positioner 542 contacts the drill rod 43, the continued expansion of the expansion bladder 53 will be blocked by 451, resulting in backward expansion. Figure 7 , thereby providing a slight extrusion to the expansion sleeve 522 to move toward the inside of the anchor hole, thereby improving the inverted support effect of the expansion sleeve 522.

[0041] It should be noted that the above-mentioned expansion bladder 53 is not limited to being used in combination with the expansion sleeve 522 , but can also be used in combination with the expansion arc plate 521 .

[0042] In the actual construction process, it is also possible to encounter a situation where the soil in some areas of the slope a surface is relatively soft, especially when the synchronous grouting drilling is carried out, or the soil near the outer periphery of the anchor hole is relatively moist due to other conditions, which is also prone to external soil collapse, thereby affecting the stability of the expansion support structure 52. For this reason, refer to the attached manual Fig.10In 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 the annular sandbag 63 is sleeved on the periphery of the expansion structure 52. The counterweight plate 64 is an annular structure, and the counterweight plate 64 is also sleeved on the periphery of the expansion 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 annular sandbag 63 is pressed by the downward pressure of the counterweight plate 64, so that the annular sandbag 63 can be stably laid on the surface of the soil layer outside the anchor hole, forming static pressure, reducing the occurrence of collapse, and improving the fixing strength of the expansion structure 52.

[0043] Furthermore, the static pressure assembly 6 also includes a support frame 61, which is fixedly mounted on the end of the guide frame 41, and a plurality of positioning nail rods 62 are slidably mounted on the support frame 61, and the plurality of positioning nail rods 62 are arranged around the expansion structure 52, and the annular sandbags 63 are arranged on the inner sides of the plurality of support frames 61, and the counterweight plate 64 is slidably matched with the positioning nail rods 62, and the counterweight plate 64 is also provided with a pulling structure 65. By adopting the above scheme, before the actual drilling, the end of the guide frame 41 can be driven close to the surface of the slope a, so that each positioning nail rod 62 can slide freely according to its own situation and contact with the surface of the slope a, forming The circular sandbag 63 is formed into a positioning support. At this time, the annular sandbag 63 is naturally attached to the surface of the slope a, and the counterweight plate 64 is controlled to move upward by the pulling structure 65 (the pulling structure 65 can adopt a pull rope structure, which is manually operated to lift, or a mechanical structure can be used to control the lifting), and then released to make the counterweight plate 64 impact downward to tamp the annular sandbag 63. With the help of the transmission of the annular sandbag 63, the soil on the surface of the slope a to be drilled is compacted and is less likely to collapse. In addition, under the positioning support of the positioning nail rod 62 on the annular sandbag 63, under the static pressure state, the pressure applied by the counterweight plate 64 and the annular sandbag 63 is also more stable.

[0044] In the above embodiment, in order to improve the stability of the construction platform 2, a platform positioning component 21 can also be set on the construction platform 2. Figure 2 and Figure 3 The platform positioning assembly 21 includes a positioner 211 (such as a nail or a pressure plate structure, etc.), and the positioner 211 is installed on the construction platform 2 through a telescopic controller 212, and the platform positioning assembly 21 is provided with at least two groups, upper and lower, and each group is provided with two left and right. Then, in actual use, according to the actual situation, the positioner 211 is adjusted to extend forward, contact and fix with the surface of the slope a, so as to adjust the posture of the construction platform 2 and make the construction platform 2 more stable.

[0045] For further information, please refer to the attached manual. Figure 3The drilling assembly 4 is installed in the construction platform 2 through a flip support platform 22. The flip support platform 22 includes a fixed frame 221 and a flip frame 222. The flip frame 222 is rotatably installed on the fixed frame 221, and a flip controller 223 is arranged between the flip frame 222 and the fixed frame 221. The flip controller 223 is used to drive the flip frame 222 to flip. The guide frame 41 is installed on the flip frame 222, so that the drilling angle of the drilling assembly 4 can be freely adjusted in actual use.

[0046] It should be noted that the telescopic controller 212, the flip controller 223 and the linear drive 511 used in this embodiment are all commonly used linear drive equipment. Among them, in order to ensure the driving force, a hydraulic cylinder structure is preferred. At the same time, the constructed 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 cooperating with square opening in the square opening process, and hoisting the inverted siphon pipe during the subsequent laying of the inverted siphon pipe, etc., achieving multiple uses in one go.

[0047] Based on the above implementation mode, refer to the attached Fig.12 This embodiment also provides a high and steep slope construction method, which specifically includes the following steps: Step 1: Build a tower crane 1 at the corresponding position on the top of slope a according to construction requirements; Step 2: Using the tower crane 1 and the square-cutting machine to square (i.e., excavate) and level the slope a to form the slope required by the construction; Step 3: Assemble the construction platform 2 and the tower crane 1, and set 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; Step 4, start the drilling assembly 4, enter and exit the preliminary drilling, and stop drilling after drilling to the required length of the expansion support structure 52; Step 5: Control the inverted support propulsion frame 51 to move forward, so that the expansion support structure 52 is inserted into the drilled hole, and then control the expansion support structure 52 to expand, contact and press against the inner wall of the hole, thereby forming an inverted support structure that can provide a stable support for the drill rod 43; Step 6: Start the drilling rig assembly 4 to continue drilling until an anchor hole that meets the requirements is drilled, then put in the anchor rod, perform grouting, and complete the anchoring operation; Step 7: Adjust construction platform 2 to the next construction area until all anchor points are constructed.

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
