Description
Technical Field
[0001] The present invention relates to the field of anchor pile structure construction, and more specifically, to a scaffolding type anchor pile structure construction device. Background Art
[0002] During the construction of expressways, high slopes or high fills are inevitably formed. These engineering activities are likely to induce or aggravate the occurrence of geological disasters along the highway. In terms of operating expressways, due to frequent extreme weather, dynamic loads from vehicles, and increased service life, the properties of rock and soil along the highway are showing a trend of continuous deterioration, and anti-sliding retaining structures are also aging, damaged, and deformed, resulting in a decrease in slope protection and frequent slope disasters. Traditional retaining structures such as anti-sliding piles and retaining walls have problems such as large retaining volume, large land area, high cost, large construction site occupation, and long construction period, resulting in long traffic control period, when preventing and controlling highway slope disasters. In recent years, micro piles have been used to treat small and medium-sized shallow landslides. However, the sliding depth that can be treated by existing commonly used micro pile structures such as steel pipe piles and steel piles is generally no more than 20m. When the length of steel pipe piles, tree root piles, and steel piles exceeds 20m, their force bearing performance is poor, and it is difficult to place the piles during construction.

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.
[0017] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0018] like Figures 1 to 4As shown, the present invention provides a scaffolding type anchor pile structure construction device, including a down-the-hole drill, the down-the-hole drill includes a propulsion beam 1, a propulsion mechanism and a slewing mechanism 3 arranged on the propulsion beam, the propulsion mechanism is used to push the slewing mechanism 3 to move along the propulsion beam 1, the output end of the slewing mechanism 3 is connected to the drill rod through the drill rod joint, and also includes a pile storage barrel 9, a pile taking mechanism and a hole positioning seat; the pile storage barrel 9 is fixedly arranged on one side of the propulsion beam 1 to store the anchor bar bundle segment 5; the top of the anchor bar bundle segment 5 is provided with a docking device 4; The pile taking mechanism is rotatably connected to the propulsion beam 1, and is used to take out the anchor beam segment 5 from the pile storage barrel 9 and send it to the bottom of the slewing mechanism 3. The output end of the slewing mechanism 3 is detachably connected to the anchor beam segment 5 through the pile joint 2; the hole mouth positioning seat includes a base 10 fixedly arranged on the pile hole and a clamp arranged on the base 10. The center of the base 10 is provided with a center hole with a diameter larger than the pile hole. The clamp is used to clamp the anchor beam segment 5; two adjacent anchor beam segments 5 are connected by the docking device 4.
[0019] In this technical solution, the down-the-hole drill can adopt a conventional down-the-hole drill available on the market, as long as the drilling conditions such as the pile hole diameter and depth are met. The propulsion beam 1, the propulsion mechanism, the slewing mechanism 3, the drill rod joint and the drill rod are all existing structures of the existing down-the-hole drill. On the basis of the conventional down-the-hole drill, the present invention further adds the pile storage barrel 9, the pile retrieval mechanism and the hole mouth positioning seat to meet the construction requirements of long anchor piles. Specifically, the pile storage barrel 9 is arranged on one side of the propulsion beam 1, and when one section of the anchor beam segment 5 is lowered into the pile hole, the next section of the anchor beam segment 5 can be placed in the pile storage barrel 9 simultaneously, and multiple anchor beam segments 5 are connected in sequence to form an anchor beam, and then grouting is performed in the pile hole to form the pile body of the anchor pile. The pile-taking mechanism takes out the anchor beam segment 5 from the pile storage barrel 9 and sends it to the bottom of the slewing mechanism 3, and then connects it to the pile joint. The propulsion mechanism drives the anchor beam segment 5 to be lowered into the pile hole until the upper end of the anchor beam segment 5 can be clamped and fixed by the clamp of the hole positioning seat, and then the propulsion mechanism drives the slewing mechanism 3 to reset, and the pile-taking mechanism takes the second anchor beam segment 5. After the propulsion mechanism drives the second anchor beam segment 5 to move down to the top of the first anchor beam segment 5, the two are connected by the docking device 4, and then the clamp is released to continue the anchor beam segment 5 below. Repeat the above process until the installation of all anchor beam segments is completed. The down-the-hole drill does not need to be shifted after drilling is completed, and only needs to be moved in the vertical direction to cooperate with the lifting of the anchor beam segment, eliminating the centering operation when using new lifting equipment. Moreover, a single anchor bar segment can be transported and moved using small equipment and is not restricted by the on-site construction environment.

The pile storage barrel 9 keeps the anchor beam segment 5 in an upright state to facilitate the taking operation of the pile taking mechanism. The pile storage barrel 9 can be fixedly arranged on the ground on one side of the propulsion beam 1 separately, or it can be detachably connected to the propulsion beam 1 through a connecting rod.
[0021] In another technical solution, Figure 2 As shown, the anchor bar segment includes four main bars 51 arranged in a field shape; a gap is left between two adjacent main bars 51, and a plurality of guide locating bars 52 are arranged at intervals along the vertical direction, and the guide locating bars 52 are fixedly connected to the main bars 51 on both sides. The four main bars 51 are connected as a whole by the guide locating bars 52 to form an anchor bar segment. The guide locating bars 52 are not arranged along the entire length of the main bars 51 to reduce the weight of the entire anchor bar segment 5. The gap between two adjacent main bars 51 is used to install the docking device 4.
[0022] In another technical solution, Figure 3 As shown, the extension device includes a reinforcement plate 43, and the top and bottom surfaces of the reinforcement plate 43 are rotatably connected with a plurality of sleeves 41, respectively. The sleeves 41 and the main bars 51 are arranged one by one and are threadedly connected with the corresponding main bars 51. Each sleeve 41 on the top surface of the reinforcement plate 43 is threadedly connected with each main bar 51 of the upper anchor bar segment 5, and each sleeve 41 on the bottom surface is threadedly connected with each main bar 51 of the lower anchor bar segment 5. The upper and lower anchor bar segments are kept stationary, and the two are connected by rotating each sleeve 41. In order to further improve the construction efficiency, except for the top anchor bar segment, the other anchor bar segments 5 are installed with the docking device 4 on the top before being transported to the construction site. When docking, it is only necessary to connect the upper anchor bar segment 5 with the docking device 4 on the top of the lower anchor bar segment 5.
[0023] In another technical solution, a reinforcement ring 42 is fixedly provided at one end of the sleeve 41, and a plurality of L-shaped limit blocks 44 are provided on the top and bottom surfaces of the reinforcement disk 43 corresponding to each sleeve. The vertical end of the limit block 44 is fixedly connected to the reinforcement disk 43, and the horizontal end thereof is in contact with the reinforcement ring 42 to limit the displacement of the sleeve 41 in the vertical direction and allow the sleeve 41 to rotate horizontally. The plurality of limit blocks 44 are symmetrically arranged about the center of the sleeve 41, and the distance between the horizontal end of the limit block 44 and the top or bottom surface of the reinforcement disk 43 is exactly the thickness of the reinforcement ring 42, so that the sleeve 41 can only rotate horizontally within the space enclosed by the limit blocks 44.
[0024] In another technical solution, Figure 4 As shown, the pile joint 2 includes a screw rod 21, a fixed disk 24 fixedly arranged at the bottom of the screw rod 21, and a plurality of connecting rods 23; the top end of the screw rod 21 is detachably connected to the output end of the rotary mechanism 3; a movable sleeve 22 is threadedly connected to the screw rod 21; the fixed disk 24 is symmetrically provided with a plurality of slideways that penetrate up and down about its center, and the slideways are arranged one by one with the connecting rods 23, one end of the connecting rod 23 is rotatably connected to the side wall of the movable sleeve 22, and the other end is rotatably connected to a slider, and the two sides of the slider are slidably connected to the slideway; the bottom of the slider is provided with an L-shaped block 25, the vertical part of the block 25 is fixedly connected to the slider, and the horizontal part extends toward the center of the fixed disk 24. After the anchor beam segment 5 is sent to the bottom of the rotary mechanism 2 by the pile taking mechanism, the rotary mechanism 2 is lowered by the propulsion mechanism to the two sides of the reinforcement disk 43 of the docking device 4 where each of the blocks 25 is located at the top of the anchor beam segment 5. Then, the rotating mechanism 3 rotates to drive the movable sleeve 22 to move upward, and the connecting rod 23 drives each of the clamping blocks 25 to move synchronously toward the center of the fixed plate 24, thereby clamping the reinforcement plate 43.
[0025] In another technical solution, Figure 2 As shown, the clamp includes two support plates symmetrically arranged on the base 10 about the center of the base 10 and two horizontally arranged driving cylinders 11; the fixed end of the driving cylinder 11 is fixedly connected to the support plate, and the movable end thereof is fixedly connected to a first gripper 12; the two driving cylinders 11 are arranged in opposite directions of extension and contraction, and the two first grippers 12 are arranged in an up-and-down staggered manner. The anchor bar segment 5 is clamped together by the two first grippers 12.
[0026] In another technical solution, Figure 1As shown, the pile-taking mechanism includes a support arm 6, a slewing arm, a slewing drive device 7 and a second gripper 8; one end of the support arm 6 is fixedly connected to the propulsion beam 1, and the other end is fixedly connected to the slewing drive device 7; the output end of the slewing drive device 7 is fixedly connected to one end of the slewing arm, and the other end of the slewing arm is fixedly connected to the second gripper 8. The slewing drive device 7 drives the slewing arm to rotate toward the pile storage barrel 9, and then the second gripper 8 grabs the anchor bar segment 5 from the pile storage barrel 9, and then the slewing arm rotates to deliver the anchor bar segment 5 to the bottom of the slewing mechanism 2. The slewing drive device 7 can be a rotary motor or a hydraulic rotary cylinder. Both the first gripper 12 and the second gripper 8 can be conventional mechanical grippers that meet the grabbing force.
[0027] The present invention also provides a construction method using the scaffolding type anchor pile structure construction device, comprising the following steps: S1, after drilling a pile hole in the soil using the down-the-hole drill, disassemble the drill rod and the drill rod joint, and connect the pile joint 2 to the slewing mechanism 3; at the same time, place the first anchor beam segment into the pile storage barrel 9; S2, locate the seat at the top of the pile hole, then take the first anchor beam segment in the pile storage barrel 9 to the bottom of the slewing mechanism 3 through the pile taking mechanism, and then connect the pile joint 2 with the first anchor beam segment; at the same time, place the second anchor beam segment in the pile storage barrel 9; S3, lowering the first anchor beam segment into the pile hole by the down-the-hole drill until the upper end of the first anchor beam segment is located in the hole opening positioning seat and is clamped and fixed by the clamp; after releasing the connection between the pile joint 2 and the first anchor beam segment, reset it; S4, take the second anchor beam segment in the pile storage barrel 9 to the bottom of the slewing mechanism 3 through the pile taking mechanism, and then connect the pile joint 2 with the second anchor beam segment; at the same time, place the third anchor beam segment in the pile storage barrel 9; S5, lowering the second anchor beam segment by the down-the-hole drilling rig until the bottom of the second anchor beam segment is respectively inserted into the docking device 4 at the top of the first anchor beam segment, connecting the first anchor beam segment with the second anchor beam segment; loosening the clamp, and continuing to lower the first two anchor beam segments until the upper end of the second anchor beam segment is located in the hole positioning seat and is clamped and fixed by the clamp; after releasing the connection between the pile joint 3 and the second anchor beam segment, reset it; S6, repeating steps S4-S5 until all the reinforcement tendon segments are installed and the last anchor tendon tendon segment extends out of the pile hole; S7, burying a grouting pipe in the pile hole, fixing the grouting pipe with the anchor bar segment, and injecting grout into the pile hole through the grouting pipe to complete the construction of an anchor bar pile; S8. Repeat the above steps, and after completing the construction of each anchor pile in turn, construct a connecting beam on the top of each anchor pile, and the top of the last section of the anchor bundle extends into the connecting beam.
[0028] In the above process, the resetting in step S3 and step S5 refers to driving the slewing mechanism 3 to rise to the initial position by the propulsion mechanism. The connecting beam connects the anchor piles into a whole to form a scaffolding anchor pile structure. The force of the anchor pile is transmitted through the connecting beam to form a pile-rock composite effect, thereby improving the shear and bending resistance of the scaffolding anchor pile structure. The connecting beam is a reinforced concrete structure, and the anchor beam segment extending out of the pile hole is fixedly connected to the steel cage in the connecting beam.
