Description

Technical Field

[0001] This utility model relates to civil engineering equipment, specifically to a prefabricated slope drilling and grouting system, belonging to the technical field of slope treatment equipment. Background Technology

[0002] In today's road and slope engineering field, with the continuous expansion of infrastructure construction and increasingly stringent engineering requirements, various construction stages face numerous technical challenges. Among these, slope construction issues are particularly prominent, significantly impacting the overall quality, schedule, and cost control of the project.

[0003] In existing slope drilling and grouting operations, temporary construction platforms (scaffolding) need to be erected on-site to facilitate worker operations. However, once erected, these temporary platforms are relatively fixed in position, making it difficult to quickly and conveniently move and adjust them according to the construction progress or unforeseen circumstances. Furthermore, on-site platform erection is inefficient, labor-intensive, and prone to human-caused accidents due to a lack of effective safety measures. Some temporary platforms are not designed to be closely integrated with specific construction techniques (such as drilling and grouting, shotcreting, etc.), resulting in inconvenience for workers and limitations on equipment operation during construction, thus affecting construction efficiency and overall construction quality. Utility Model Content

[0004] To address the problems of low flexibility, low efficiency, and low safety of temporary on-site construction platforms in existing technologies, this utility model provides a prefabricated slope drilling and grouting system. This system eliminates the need for extensive on-site scaffolding construction. Instead, it integrates a drilling and grouting device with a construction operation basket. The operation basket, carrying the drilling and grouting device, can be flexibly moved across the slope surface via anchor bolts, tie cables, and winches. Furthermore, the drilling and grouting device is designed to move within the operation basket within a small range. This allows for initial coarse adjustment of the device's position on the slope surface using anchor bolts, tie cables, and winches, followed by fine-tuning through its own movement to achieve precise drilling and grouting. Because the entire system is composed of multiple coupled prefabricated devices, it eliminates the need for extensive on-site installation, significantly improving construction efficiency. Moreover, compared to ordinary scaffolding, the operation basket offers better overall safety protection.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A prefabricated slope drilling and grouting system includes an operating basket, fixed anchor bolts, tie cables, winches, and drilling and grouting devices. The operating basket includes a rectangular base frame and a guardrail surrounding the rectangular base frame. The winches are installed at both ends of the rectangular base frame. Fixed anchor bolts are installed at both ends of the slope crest. The fixed anchor bolts located on the same side of the slope and the winches are connected by tie cables, thereby dragging the operating basket across the slope surface.

[0007] The drilling and grouting device includes a lifting base, a rotary drive, a drill rod, and a drill bit. The bottom end of the lifting base is mounted on the surface of a rectangular base frame, and the rotary drive is located at the top of the lifting base. One end of the drill rod is connected to the rotary drive, and the other end is equipped with the drill bit.

[0008] Preferably, the system also includes a braking protection device. The braking protection device includes a suspension plate base and sensing pulleys. A through-hole is provided in the center of the suspension plate base, and multiple sensing pulleys are installed within this through-hole. Each sensing pulley is equipped with a force sensor synchronously associated with all winches. Each traction cable must pass over the sensing pulleys on the same side before connecting to the fixed anchor and the winch respectively, ensuring that the suspension plate base is positioned above the operating basket. Preventive cables extending directly to the operating basket are also provided at both ends of the suspension plate base.

[0009] Preferably, the winch is located at the bottom of the rectangular base frame, and reversing tensioning pulleys are provided on both outer sides of the rectangular base frame. One end of the traction cable is connected to the winch, and the other end first passes around the reversing tensioning pulley on the same side as the winch and then is connected to the brake protection device and the fixed anchor in sequence.

[0010] Preferably, the reversing tensioning pulley is connected to the end of the rectangular base frame via a telescopic fixing frame, and the telescopic fixing frame is used to adjust the distance the reversing tensioning pulley extends to the outer side of the end of the rectangular base frame.

[0011] Preferably, a winch is installed at each of the four corners of the rectangular base frame, and each winch is independently connected to a fixed anchor rod via a traction cable. Each winch is covered with a protective cover.

[0012] Preferably, the system also includes wheels, which are connected to the end of the rectangular base frame near the slope via a rotary support. The direction of travel of the wheels is adjusted by the rotary support.

[0013] Preferably, the system also includes a cutting plate, which comprises a platform and a cutting rod. The platform is a rectangular plate or a rectangular frame. A slide is provided on the upper surface of the platform, and a slide rail extending along its width is provided on the lower surface of the rectangular base frame. The platform is connected to the rectangular base frame via the slide and the slide rail. The cutting rod is located at the end of the platform near the slope side and extends towards the slope surface.

[0014] Preferably, the lifting base is mounted on the rectangular base frame via a first guide wheel and a horizontal guide rail extending along the length of the rectangular base frame surface.

[0015] Preferably, a longitudinal guide rail extending along the width direction is also provided on the surface of the rectangular base frame. The longitudinal guide rail is mounted on the horizontal guide rail via a first guide wheel, and the lifting base is mounted on the longitudinal guide rail via a second guide wheel.

[0016] Preferably, the fixed anchor bolt includes a main anchor bolt, an upper auxiliary anchor bolt, and a lower auxiliary anchor bolt. The top of the upper auxiliary anchor bolt is connected to the upper part of the main anchor bolt, and its bottom end extends downwards towards the slope surface and inserts into the soil at the top of the slope. The top of the lower auxiliary anchor bolt is connected to the lower part of the main anchor bolt, and its bottom end extends downwards towards the slope surface and inserts into the soil at the top of the slope. A tie cable is connected to the main anchor bolt located between the tops of the upper and lower auxiliary anchor bolts. Both the upper and lower auxiliary anchor bolts are Y-shaped structures with forked bottoms.

[0017] In this invention, the operating basket includes a rectangular base frame (a prefabricated plate or frame structure; to reduce weight, a steel frame beam structure is generally used, and wooden or bamboo boards can be selectively laid on it) and a guardrail surrounding the rectangular base frame. The guardrail is an assembled structure, which can be installed on-site or pre-installed. The guardrail has an openable gate. Generally, the side of the rectangular base frame closest to the slope surface may not have a guardrail or may have a lower guardrail to facilitate worker operation. Winches (usually with their own independent drive motors) are fixedly installed at both ends of the rectangular base frame. The winches are connected to fixed anchor bolts at the top of the slope via pull cables (following the principle of connection on the same side, i.e., winches on the same side of the slope are connected to fixed anchor bolts via independent pull cables). By controlling the raising and lowering of the pull cables through the winches, the lifting, lowering, and translation of the rectangular base frame (i.e., movement between different areas of the slope surface) can be adjusted. It should be noted that the start-up of the winches located at both ends of the rectangular bottom frame is independently controlled (they can be integrated into a switch control box located inside the operating basket for workers to operate in real time, or they can be remotely controlled). The smooth movement of the operating basket is achieved through the combined action of the winches on both sides, thereby significantly improving construction efficiency.

[0018] Furthermore, the rotary drive, drill rod, and drill bit of the drilling and grouting device are mounted in the operating basket via a height-adjustable lifting base (such as an electric hydraulic lifting rod (similar to a jack structure) or a folding lifting frame with an independent drive motor, which can be located at the bottom or to the side). Once the operating basket has moved to the approximate height of the target drilling point, the height of the drill rod and drill bit can be further adjusted via the lifting base to achieve precise positioning of the drilling point. It should be noted that the rotary drive is used to drive the drill rod to rotate; it can have its own drive motor or share a drive motor with the lifting base, but their start and stop are operated independently.

[0019] Furthermore, to achieve more precise drilling point positioning, the lifting base is mounted on a rectangular base frame via a mechanism consisting of a first guide wheel, a horizontal guide rail, a second guide wheel, and a longitudinal guide rail. Specifically, the lifting base moves horizontally (along the length of the rectangular base frame) via the first guide wheel on the horizontal guide rail, while the horizontal guide rail moves longitudinally (along the width of the rectangular base frame) via the second guide wheel on the longitudinal guide rail, thus enabling the vertical movement of the lifting base. In other words, the rotary actuator, drill rod, and drill bit can move horizontally, vertically, and longitudinally within the operating basket, thereby achieving precise drilling point positioning and significantly improving construction efficiency.

[0020] In this invention, to further improve the stability of the operating basket as it moves along the slope, multiple independent winches are installed at both ends of the rectangular base frame. Each winch is connected to an independent fixed anchor rod via an independent traction cable. For example, one winch is installed at each of the four corners of the rectangular base frame, and two fixed anchor rods are installed at both ends of the slope crest. The four winches and four fixed anchor rods are connected correspondingly by four traction cables (connection on the same side). The installation of the four winches effectively provides a restrictive positioning for the operating basket, greatly reducing its swaying and improving its stability, thus facilitating stable operation for workers and significantly enhancing the safety of the suspended basket.

[0021] In this invention, to further improve the stability of the operating basket, a braking protection device with a special structure and function is also provided on the upper side of the operating basket. Each traction cable must first pass over the sensing pulley of the braking protection device before being connected to the fixed anchor and the winch respectively. That is to say, the suspension plate seat of the braking protection device is suspended above the operating basket by the pulling action of multiple traction cables. At this time, any traction cable will apply an external force to the sensing pulley it contacts. The force sensor installed on the sensing pulley senses this external force in real time. If the external force decreases or disappears suddenly (the traction cable breaks), the force sensor will transmit a signal to lock all the winches associated with it (so that other unbroken traction cables stop retraction or extension). Furthermore, the force sensor can also be associated with the drilling and grouting device at the same time, and the drilling and grouting device can be shut down simultaneously to avoid damage to it. The current state remains unchanged until a new traction cable is replaced and the system is restarted to continue working.

[0022] Furthermore, to prevent the tension cables at both ends of the operating basket from occupying space inside the basket when extending towards the brake protection device, a corresponding number of reversing tensioning pulleys are installed at both ends of the rectangular base frame, extending outwards from the ends of the rectangular base frame (i.e., horizontally away from the rectangular base frame). After each tension cable extends from the winch, it passes sequentially through the reversing tensioning pulley and the induction pulley on the same side before connecting to the fixed anchor rod on the same side (i.e., the tension cable is folded into a Z-shaped form). Furthermore, the tensioning pulleys are connected to the ends of the rectangular base frame via telescopic fixing frames (such as jack-like telescopic rods or folding telescopic frames similar to electric gates). In other words, the distance the reversing tensioning pulleys extend outwards from the ends of the rectangular base frame is adjustable, thereby allowing adjustment of the tension of the tension cables and facilitating rapid online replacement and repair in case of cable breakage.

[0023] In this invention, a traveling wheel is provided on the bottom side of the rectangular base frame near the slope via a rotating support. The rotating support consists of a rotating shaft and a motor. The motor drives the rotating shaft to rotate, thereby adjusting the traveling direction of the traveling wheel. The traveling wheel assists the operating basket in moving on the slope surface and also provides auxiliary support when the operating basket does not need to move.

[0024] In this invention, a cutting plate that can move towards one side of the slope is also provided at the bottom of the rectangular base frame. The cutting plate includes a platform and a cutting rod. The cutting rod is located at the end of the platform near the slope side and extends towards the slope side. When the operating basket moves to the target position on the slope, the platform of the cutting plate extends to the gap between the rectangular base frame and the slope side (where workers can stand) through the sliding seat and the slide rail extending along the width direction of the rectangular base frame, and the cutting rod is inserted into the soil of the slope side, thereby improving the stability of the rectangular base frame and the safety of the operating basket. When the operating basket needs to be moved again, simply drive the sliding seat (which can be driven by an independent motor) to move backward and pull out the cutting rod.

[0025] In this invention, the fixed anchor bolt includes a main anchor bolt, an upper auxiliary anchor bolt, and a lower auxiliary anchor bolt. Both the upper and lower auxiliary anchor bolts are Y-shaped structures with forked lower ends, and are inclinedly arranged on the side of the main anchor bolt closest to the slope surface. The connection between the tension cable and the main anchor bolt is located between the upper and lower auxiliary anchor bolts. Through the design of the main anchor bolt, upper auxiliary anchor bolt, and lower auxiliary anchor bolt, the stability of the fixed anchor bolt can be improved, thereby ensuring the safety of the system.

[0026] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0027] 1. The prefabricated slope drilling and grouting system of this utility model integrates the drilling and grouting device with the prefabricated operating basket. By utilizing the synergistic effect of specially arranged fixed anchors, traction cables, winches, etc., it can achieve rapid and stable slope drilling and grouting operations, and significantly reduce labor costs, shorten the construction period, and ensure safe production.

[0028] 2. The prefabricated slope drilling and grouting system of this utility model has the advantages of simple structure, quick and convenient use, accurate drilling and grouting positioning, low preparation and maintenance cost, high safety, strong adaptability and good practicality.

Example 10

[0060] The embodiment 9 is repeated, except that the fixed anchor 2 includes a main anchor 201, an upper auxiliary anchor 202, and a lower auxiliary anchor 203. The top end of the upper auxiliary anchor 202 is connected to the upper part of the main anchor 201, and its bottom end extends downwards towards the slope surface and is inserted into the soil at the top of the slope. The top end of the lower auxiliary anchor 203 is connected to the lower part of the main anchor 201, and its bottom end extends downwards towards the slope surface and is inserted into the soil at the top of the slope. The tension cable 3 is connected to the main anchor 201 located between the top ends of the upper auxiliary anchor 202 and the lower auxiliary anchor 203. Both the upper auxiliary anchor 202 and the lower auxiliary anchor 203 are Y-shaped structures with forked bottoms.

[0061] When using the prefabricated slope drilling and grouting system of this utility model, first fix the fixed anchor rods 2 at both ends of the slope top (two rods at each end); then connect the pull cables 3 to the winches 4 set at the bottom of the rectangular base frame 101 according to the principle of connection on the same side. The middle of all pull cables 3 must pass through the induction pulley 602 of the braking protection device 6 and the reversing tensioning fixed pulley 7 of each winch 4. Then, workers selectively drive each winch 4 to retract and extend the tension cable 3. With the assistance of the traveling wheels 103, the operating basket 1 is moved to the approximate location on the slope where drilling is required. The insert plate 9 is then pushed towards the slope side, and the insert rod 902 is deeply inserted into the slope soil. The drill bit 504 is then precisely adjusted and aligned with the drilling point using the first guide wheel 505, horizontal guide rail 506, second guide wheel 508, longitudinal guide rail 507, and lifting base 501. The rotary transmission 502 is then activated, driving the drill rod 503 to rotate, and drilling is performed using the drill bit 504. After drilling is completed, grouting can be performed. When the operating basket 1 needs to be moved again, the insert plate 9 is first returned to its original position. Simultaneously, the rotary support 104 is driven to adjust the traveling wheels 103 towards the next working area. Then, the winches 4 are selectively driven to retract and extend the tension cable 3 until the operating basket 1 reaches the target area. It should be noted that when a certain tension cable 3 suddenly breaks, the external force on the sensing pulley 602 in contact with it decreases dramatically (or even to zero) instantly. The force sensor 603 connected to the sensing pulley 602 detects this signal and feeds it back to each winch 4 and the drilling and grouting device 5, causing them to shut down immediately. After the workers replace the new tension cable 3 and drive the reversing tensioning pulley 7 through the telescopic fixed frame 8 to tension the new tension cable 3, the work can continue.
