Description

Technical Field

[0001] This application relates to the technical fields of geotechnical engineering and geological disaster prevention, and in particular to a drilling device and construction method for complex steep slopes. Background Technology

[0002] In the natural environment, there are a large number of unstable slopes, especially the steep slopes on both sides of mountain roads and railways, which pose hazards such as slope instability, landslides and collapses. In order to ensure traffic safety and the safety of people's lives, it is necessary to take geotechnical engineering measures to reinforce slopes with high geological disaster risks.

[0003] In related technologies, before slope reinforcement, it is often necessary to drill holes in the slope, and then insert reinforcement structures and lay reinforcement nets or other reinforcement structures. Currently, anchor drilling is mostly used for slope drilling. The operator holds the anchor drilling tool and starts the machine. While the drill bit of the anchor drilling tool is rotating, the operator continuously presses down and lifts up to complete the drilling operation.

[0004] As can be seen from the above technical solutions, in the existing technology, the drilling principle of the anchor drilling tool is continuous manual drilling. For general slope conditions, this drilling method is perfectly capable. However, when encountering complex conditions such as soft soil, uneven slope surface and many shrubs, soil and surrounding debris will continuously enter the hole during drilling, resulting in low drilling efficiency and the hole being easily filled with debris, thus leading to poor drilling quality. Summary of the Invention

[0005] This application provides a drilling device and construction method for complex steep slopes, which has the advantages of improving drilling efficiency and drilling quality.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] On one hand, this application provides a drilling device for complex steep slopes, including a fixing component for fixing to the slope surface, a support plate installed on the surface of the fixing component, and a drilling assembly installed on the support plate and slidingly engaging with the support plate. The fixing component includes a fixing plate for fixing to the slope surface and a drilling positioning plate fixed to the fixing plate. The drilling positioning plate has a hollow soil discharge cavity with its opening facing the bottom of the slope. A soil cleaning component is installed inside the soil discharge cavity. A transmission component is linked between the drilling assembly and the soil cleaning component so that when the drilling assembly is lifted, the soil cleaning component discharges the soil brought up by the lifting of the drilling assembly into the soil discharge cavity.

[0008] Optionally, the drilling positioning plate has a drilling hole on its surface, and the drilling assembly includes a lifting plate and an anchor drilling machine. The lifting plate and the support plate slide together in the vertical direction, and the anchor drilling machine is fixed to the bottom of the lifting plate, with the spiral drill bit of the anchor drilling machine facing the drilling hole.

[0009] Optionally, the support plate has at least one vertically extending sliding hole on its surface, and the lifting plate is fixedly provided with a sliding strip, which passes through the sliding hole and slides in cooperation with it.

[0010] Optionally, the soil cleaning component includes an installation strip, a soil cleaning plate, and a soil cleaning brush. There are two installation strips that slide in conjunction with the drilling positioning plate. The sliding direction of the installation strip is consistent with the slope inclination direction. The two installation strips are respectively located on both sides of the anchor drilling machine. There are multiple sets of soil cleaning plates, and multiple sets of soil cleaning plates are installed at the bottom position of the installation strip. The soil cleaning brush is fixedly installed at the bottom position of the soil cleaning plate.

[0011] Optionally, the soil clearing plate is hinged to the installation strip, the hinge axis of the soil clearing plate and the installation strip is perpendicular to the slope inclination direction, and the hinge axis of the two is located on the side of the soil clearing plate near the top of the slope, and the rotation angle range of the soil clearing plate is limited to rotating from the vertical state to the bottom of the slope to the horizontal state.

[0012] Optionally, the drilling positioning plate has cleaning sliding holes extending along the slope direction on both sides. Each mounting strip has a cleaning slider that slides with the cleaning sliding hole at its end. The transmission component is provided in two sets, which are used to drive the two mounting strips to slide along the cleaning sliding hole respectively.

[0013] Optionally, the transmission component includes a threaded rod, a transmission gear, a rack, and a connecting rod. The threaded rod is fixed to the side of the lifting plate and faces vertically downward. A mounting seat for installing the transmission gear is fixedly provided on the drilling positioning plate. The transmission gear has a threaded hole in the center that is threaded to engage with the threaded rod. The rack meshes with the transmission gear. The bottom of the rack is fixedly connected to the cleaning slider through a connecting rod. When the lifting plate rises, the transmission gear meshes with the rack to drive the rack to move towards the bottom of the slope.

[0014] Optionally, a vertical support rod is fixedly provided on the side wall of the drilling positioning plate, and a limiting sleeve for limiting the sliding direction of the rack is fixedly provided on the top of the support rod.

[0015] Optionally, the fixing plate is provided with anchor screws for insertion into the slope.

[0016] On the other hand, this application provides a drilling method for complex steep slopes, comprising the following steps:

[0017] S1. Determine the location of the hole to be drilled on the slope, install the fixing parts, and make the drilling hole face the drilling location;

[0018] S2. Locate the drilling position and drive the fixing plate in using anchor bolts to fix the fastener to the slope.

[0019] S3. Start the anchor bolt drilling machine. The operator holds the handle of the sliding bar and starts to press down, which drives the anchor bolt drilling machine to press down and drill a hole. After drilling to a certain depth, the anchor bolt drilling machine is lifted up. This action is repeated continuously.

[0020] By adopting the above technical solution, the drilling location on the slope is determined in advance before drilling. The entire fixing component is fixed to the slope using anchor bolts. The fixing component can uniquely determine the drilling location and avoid the influence of the surrounding environment on the drilling operation. At the same time, the fixing component can isolate the soil around the drilling location from the drilling area, thereby avoiding problems such as borehole wall collapse and surrounding soil collapse interference during the drilling process. During the drilling process, the operator presses down the anchor bolt drilling machine to adjust the drilling depth. When the anchor bolt drilling machine is raised, the auger bit of the anchor bolt drilling machine carries out the soil. At the same time, the threaded engagement between the threaded rod and the transmission gear drives the transmission gear to rotate. The transmission gear then drives the rack to move horizontally, so that the transmission gear, through the connecting rod, drives the installation strip and the soil clearing plate to move towards the bottom of the slope. Therefore, the soil brought out by the drilling can be discharged from the soil discharge cavity in time, further reducing the amount of soil brought out by the drilling to re-enter the borehole, greatly improving drilling efficiency and borehole quality.

[0021] In summary, this application has the following technical effects:

[0022] By installing fixing components in the drilling area, the positioning and isolation functions of the fixing components can keep the drilling area independent, reduce the impact of the surrounding environment on the drilling operation, and improve the drilling quality.

[0023] Through the transmission of the transmission components, during the drilling operation, the hoisting machine can be lifted to drive the soil removal component to remove the soil from the soil discharge cavity, which further reduces the interference of the surrounding soil on the drilling operation and indirectly improves the drilling quality.

[0024] By setting a set of transmission components and a set of soil cleaning components on each side of the anchor bolt drilling machine, the soil cleaning components can perform soil cleaning operations simultaneously on both sides of the auger drill bit of the anchor bolt drilling machine. This not only avoids interference from the soil cleaning components to the drilling operation, but also improves the soil discharge efficiency inside the soil discharge cavity, thereby improving the drilling quality.

Implementation

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] Reference Figures 1-3 This application provides a drilling device and construction method for complex steep slopes, including a fixing component 1. The fixing component 1 is used to install at the drilling position on the slope surface to locate, reinforce and guide the drilling operation. A drilling component 3 for drilling is installed on the fixing component 1. A soil cleaning component 4 is set inside the fixing component 1. A transmission component 5 is set between the soil cleaning component 4 and the drilling component 3. While the drilling component 3 is drilling, the transmission component 5 drives the soil cleaning component 4 to work synchronously, thereby preventing the soil produced by drilling from re-entering the hole and improving drilling efficiency and hole quality.

[0034] like Figure 2As shown, the fixing component 1 includes a fixing plate 11 and a drilling positioning plate 12. The fixing plate 11 is fixedly connected to the drilling positioning plate 12. The fixing plate 11 is fixed to the slope surface by two anchor bolts 111. The drilling positioning plate 12 is hollow inside to form a soil discharge cavity 121, and the bottom and the side surface facing the bottom of the slope are both through. A drilling hole 122 is opened at the position of the upper surface of the drilling positioning plate 12. The drilling assembly 3 is installed on the surface of the drilling positioning plate 12 with the drill bit vertically facing the drilling hole 122, thereby guiding the drilling operation and ensuring that the position of the slope to be drilled can be covered and surrounded, avoiding landslides and hole collapses caused by soft soil during drilling, thus improving the drilling accuracy and hole quality.

[0035] like Figure 2 As shown, a support plate 2 is fixedly mounted on the upper surface of the drilling positioning plate 12. The support plate 2 is located on the side of the drill hole 122 facing the bottom of the slope. The support plate 2 includes a horizontal plate 21 and a vertical plate 22 fixedly connected to the horizontal plate 21. The horizontal plate 21 is fixed to the drilling positioning plate 12 by bolts, and the vertical plate 22 is vertically arranged. Two vertically arranged sliding holes 221 are opened on the vertical plate 22, and a return spring 222 is installed in each sliding hole 221.

[0036] The drilling assembly 3 includes a lifting plate 31 and an anchor drilling machine 32. Two sliding bars 311 are fixedly installed on one end of the lifting plate 31 facing the vertical plate 22. The sliding bars 311 pass through the sliding hole 221 and slide in the vertical direction with the sliding hole 221. The bottom end of the return spring 222 is fixed to the bottom of the sliding hole 221, and the top end of the return spring 222 is fixedly connected to the sliding bar 311. A handle is fixed to the end of the sliding bar 311. The anchor drilling machine 32 is fixed to the bottom of the lifting plate 31, and the drill bit is vertically downward and facing the drilling hole 122. After determining the drilling location on the slope, the fixing component 1 is fixed to the slope. Then, the operator presses down the lifting plate 31 and starts the anchor bolt drilling machine 32 at the same time. This allows the anchor bolt drilling machine 32 to move downward through the drilling hole 122 to achieve drilling. During the drilling process, the drilling position can be accurately determined to achieve efficient drilling. In addition, the drilling positioning plate 12 can isolate the drilling area from other external areas, avoiding the influence of the external environment on the drilling and indirectly improving the drilling quality.

[0037] Combination Figure 3 and Figure 6The soil cleaning component 4 is installed inside the soil discharge cavity 121. The soil cleaning component 4 includes an installation strip 41, a soil cleaning plate 42, and a soil cleaning brush 43. A cleaning sliding hole 123 is opened on each of the opposite sides of the drilling positioning plate 12, and the extension direction of the cleaning sliding hole 123 is consistent with the slope inclination direction. There are two installation strips 41, which are respectively set on both sides of the drill bit of the anchor drilling machine 32. A cleaning slider 411 is fixedly set at the end of the installation strip 41 facing the cleaning sliding hole 123. The cleaning slider 411 is embedded in the cleaning sliding hole 123 and slides in cooperation with the cleaning sliding hole 123. There are multiple soil cleaning plates 42, which are arranged in sequence at the bottom of the installation strip 41. The soil cleaning plate 42 is hinged to the installation strip 41. The hinge axis of the two is set horizontally and perpendicular to the slope inclination extension direction. The hinge axis is located at the edge of the installation strip 41 away from the bottom of the slope. A soil cleaning brush 43 is set at the bottom of each soil cleaning plate 42.

[0038] Combination Figure 2 , Figure 4 and Figure 5 Two sets of transmission components 5 are provided and are respectively located on both sides of the drilling hole 122. Specifically, each set of transmission components 5 includes a threaded rod 51, a transmission gear 52, a rack 53, and a connecting rod 54. A set of vertical mounting seats 6 is fixedly provided on the surface of the drilling positioning plate 12 at opposite positions on both sides of the drilling hole 122. A through hole 63 is opened at the center of the mounting seat 6. An extension plate 3111 is fixed on each opposite side of the lifting plate 31. The threaded rod 51 is rotatably connected to the bottom of the extension plate 3111 and is vertically arranged. The bottom of the threaded rod 51 extends into the through hole 63. A lower chuck 62 is fixedly provided on the top of the mounting seat 6. An upper chuck 61 is provided directly above the lower chuck 62. The upper chuck 61 and the lower chuck are fixedly connected by a connecting side ring 64. The connecting side ring 64 is located on the side close to the drilling hole 122. The drive gear 52 is installed between the upper chuck 61 and the lower chuck 62, and the transmission gear 52 is rotatably connected to both the upper chuck 61 and the lower chuck 62. A threaded hole corresponding to the through hole 63 is opened at the center of the transmission gear 52. The threaded rod 51 passes through the threaded hole and is threadedly engaged with the threaded hole. The rack 53 is located on the side of the transmission gear 52 away from the drill hole 122. The rack 53 is parallel to the upper surface of the drilling positioning plate 12 and is in the same direction as the slope. Two vertically arranged support rods 7 are fixedly installed on the side wall of the drilling positioning plate 12. A limiting sleeve 71 that nests the rack 53 and slides with the rack 53 is fixedly installed on the top of the support rod 7. The bottom center of the rack 53 is fixed to the connecting rod 54. The bottom of the connecting rod 54 is fixed to the cleaning slider 411, and the connecting rod 54 is located between the two limiting sleeves 71.

[0039] The implementation principle of this application embodiment is as follows: After determining the drilling location on the slope, the drilling location is first cleaned in advance. Then, the fixing member 1 is fixed to the slope, specifically, the drill hole 122 is aligned with the drilling location. Then, the fixing plate 11 is fixed to the slope using anchor bolts 111. Next, the operator starts the anchor bolt drilling machine 32 and holds the handle of the sliding bar 311 to press down the anchor bolt drilling machine 32 to start drilling. The drilling operation requires continuous pressing down and lifting of the anchor bolt drilling machine 32, so that the soil generated during the drilling process is carried out by the auger drill bit of the anchor bolt drilling machine 32. During the process of pressing down the anchor bolt drilling machine 32, the threaded rod 51 drives the transmission gear 52 to rotate, and the transmission gear 52 drives the rack 53 to move towards the top of the slope, thereby making The connecting rod 54, fixed to the bottom of the rack 53, drives the mounting strip 41 and the soil cleaning plate 42 to move obliquely upward in the soil discharge cavity 121. This causes the soil cleaning plate 42 and the cleaning brush to move to the position of the drilled hole 122 on one side of the slope top. Then, under the action of the return spring 222 and the lifting force of the operator, the anchor drilling machine 32 moves upward. The internal thread of the threaded rod 51 and the transmission gear 52 engages, causing the transmission gear 52 to rotate. This, in turn, drives the rack 53 to move obliquely downward along the slope top. Therefore, the rack 53 moves downward along the slope via the connecting rod 54 and the mounting strip 41, allowing the soil cleaning plate 42 and the soil cleaning brush 43 to discharge the soil generated by the drilling from the soil discharge cavity 121, preventing the soil generated by the drilling from backfilling the hole. The specific size of the drilling positioning plate 12 and the moving distance of the soil cleaning component 4 in the soil discharge cavity 121 can be customized according to the drilling depth. In summary, during drilling operations, the drilling positioning plate 12 can locate the drilling position to achieve efficient drilling. The drilling positioning plate 12 can also isolate the drilling position from the external environment, reducing the impact of the surrounding complex environment on the drilling position. In addition, the soil generated during the drilling process can be simultaneously swept away by the soil cleaning component 4 in the first instance. Furthermore, due to the hinged position between the soil cleaning plate 42 and the mounting strip 41, the soil cleaning plate 42 can rotate when it encounters soil while moving upward, avoiding the re-placement of a large amount of soil back to the top of the borehole. When the soil cleaning plate 42 moves downward, its rotation is restricted, ensuring the soil cleaning effect and greatly improving the drilling quality.

[0040] On the other hand, this application provides a drilling construction method for complex steep slopes, including the following steps:

[0041] S1. Determine the location of the borehole on the slope and mark the location. Remove any objects that may affect the location of the borehole, such as rocks and shrubs.

[0042] S11. Install the fixing component 1, so that the drill hole 122 is aligned with the marked drill hole position;

[0043] S2. Position the drilling hole and drive the fixing plate 11 into the anchor screw 111, thereby fixing the fixing part 1 and the drilling positioning part to the slope.

[0044] S21. Position the anchor drilling machine 32 directly opposite the drilling hole 122;

[0045] S3. Start the anchor bolt drilling machine 32. The operator holds the handle of the sliding bar 311 and starts to press down, which drives the anchor bolt drilling machine 32 to press down and drill. After drilling to a certain depth, the anchor bolt drilling machine 32 is lifted up. This action is repeated continuously to realize the drilling operation.
