Description

Technical Field

[0001] This application relates to the field of bridge engineering technology, and more specifically, to a construction method for manually excavated anti-slide piles based on deep trench terrain and intelligent monitoring. Background Technology

[0002] In areas with deep ravine terrain, the significant topographic features, including steep slopes and complex rock strata, coupled with the constant erosion from rainwater, make these areas prone to geological disasters. Steep slopes are susceptible to landslides under gravity, and the complex rock structures are prone to localized collapses after rainwater infiltration. These geological hazards not only pose a serious threat to surrounding construction projects but also potentially disrupt the local ecological balance. Therefore, to ensure the smooth progress of construction projects and the long-term stability of the ecological environment, effective support measures must be implemented. Anti-slide piles, as a reliable support method, can effectively resist the sliding tendency of slopes through their unique structural form and mechanical properties, enhancing the overall stability of the soil and rock mass. This achieves the goal of reinforcing the area and ultimately ensuring the safe construction of surrounding projects and maintaining ecological security.

[0003] However, the current method of fixing anti-slide piles to the inner wall of the pile hole in engineering practice has certain limitations. Fixing is achieved by the weight of the pile itself, which is only suitable for simple working conditions with shallow support and stable geological conditions. Although the traditional anchor reinforcement technology improves the fixing effect to a certain extent, this reinforcement method has obvious technical defects. Conventional anchor reinforcement can only achieve anchoring in one direction and cannot form a multi-directional constraint system. It is difficult to adapt to the complex stress environment of the pile hole wall in deep trenches. Especially in deep foundation pits or high slope projects, when the rock and soil of the hole wall are subjected to uneven lateral pressure, the anti-slide pile is prone to horizontal displacement or tilting deformation due to the lack of an effective multi-directional constraint mechanism. The existing fixing method has poor adaptability to changes in geological conditions. When encountering adverse geological conditions such as weak interlayers or fractured zones, its support effect will be further reduced.

[0004] Therefore, a construction method based on manually excavated anti-slide piles and intelligent monitoring is proposed to address the above problems. Summary of the Invention

[0005] The purpose of this application is to provide a method for constructing manually excavated anti-slide piles based on deep trench terrain and intelligent monitoring, which can form multi-directional reinforcement and effectively improve the bonding strength between the anti-slide pile and the borehole wall.

[0006] The technical solution provided in this application for the construction method of manually excavated anti-slide piles and intelligent monitoring based on deep trench terrain is as follows: The anti-slide pile, artificially excavated based on deep trench terrain, includes an installation base, a connecting frame snapped onto the installation base, and a snap-fit ​​component connected to the connecting frame and the installation base. The connecting frames are snapped together and to the installation base via the snap-fit ​​component. The installation base and the connecting frame are provided with reinforcement components that can be driven into the inner wall of the hole where the anti-slide pile is placed. The installation base and the connecting frame are provided with fixing grooves, and connecting grooves are provided on both sides of the fixing grooves. The connecting frame is provided with snap-fit ​​grooves.

The other end of the first wedge block is provided with a first spring, and the other end of the first spring is fixedly connected to the connecting groove. The first wedge block engages with the engaging groove.

[0008] By adopting the above technical solution, the connecting frame is engaged with the mounting base, the first wedge block moves, and the first spring is compressed.

[0009] Preferably, for the reinforcing nail to move, the reinforcing assembly includes a threaded rod, a reinforcing nail, and a side nail. The threaded rod is rotatably mounted on the mounting bracket and the connecting bracket. The reinforcing nail is connected to the connecting bracket and the mounting base. The side nail is rotatably mounted on the connecting bracket and the mounting base. The reinforcing nail is provided with a second wedge block. The threaded rod is located between the second wedge blocks. A second spring is sleeved on the reinforcing nail. One end of the second spring is fixedly connected to the mounting base or the connecting bracket, and the other end of the second spring is fixedly connected to the second wedge block.

[0010] By adopting the above technical solution, the second wedge block moves, and the reinforcing nail moves.

[0011] Preferably, in order to adjust the movement of the second wedge block by moving the movable block, the movable block is threadedly connected to the threaded rod, the upper end of the movable block is conical, and the movable block is located between the second wedge blocks.

[0012] By adopting the above technical solution, the threaded rod rotates, thereby adjusting the position of the moving block.

[0013] Preferably, in order to limit the movement of the movable block, a connecting rod is hinged to the movable block, and the connecting rod is hinged to the side nail.

[0014] By adopting the above technical solution, the moving block can be limited by the connecting rod.

[0015] Preferably, in order to facilitate the rotation of the connecting rod, the moving block is provided with a hinge seat, and the moving block and the connecting rod are hinged through the hinge seat.

[0016] By adopting the above technical solution, the moving block can be moved by rotating the threaded rod and by moving the connecting rod. When the moving block moves, the connecting rod folds, thus adjusting the position of the side nail.

[0017] Preferably, in order to facilitate the connection between the connecting brackets, the upper end of the threaded rod is provided with a positioning groove, and the other end of the threaded rod is provided with a connecting block, which matches the positioning groove.

[0018] By adopting the above technical solution, the threaded rods between the reinforcing components are connected through the positioning groove and the connecting block.

[0019] Preferably, to improve stability, the mounting base and the connecting frame are provided with reinforcing rods arranged in an array.

[0020] By adopting the above technical solution, the stability of the mounting base and the connecting frame is enhanced.

[0021] Preferably, to improve slip resistance, the bottom of the mounting base is provided with an anti-slip pad.

[0022] By adopting the above technical solution, the mounting base can increase the friction with the hole.

[0023] The intelligent monitoring and construction method for manually excavated anti-slide piles based on deep trench terrain includes the following steps: S1: Determine the pile location, hole depth and pile diameter using ground-penetrating radar and total station, excavate the hole to a depth of 1m, clean the bottom of the hole, install steel formwork with a verticality deviation of ≤0.5%, and tie the reinforcing bars. Generally, the lap length of the main reinforcement is ≥30d. Pour the retaining wall concrete with a layer thickness of 20~30cm, and cure until the strength meets the standard. Repeat the above operations until the designed hole depth is reached. Mark the installation reference point, then install the base and connecting frame to arrange strain, displacement, torque and tilt sensors, connect to the intelligent terminal, input the early warning threshold, and calibrate the sensor zero point and torque. S2: Level the bottom of the deep trench, lay anti-slip mats, use jacks to level the installation base, temporarily fix the installation base with expansion bolts, and check the elevation and levelness of the top surface, where the elevation error of the top surface is ±10mm; S3: Hoist the connecting frame to the top of the mounting base. The first spring pushes the wedge block into the connecting groove. The displacement sensor monitors the clamping gap. Screw in the reinforcing nails and side nails to the hole wall and monitor the torque and anchoring force.

[0024] The technical effects and advantages of this application are as follows: Compared with existing technologies, this anti-slide pile, which is manually excavated based on deep trench terrain, uses a reinforcing component. When the threaded rod rotates, it drives the moving block to move. The conical structure of the moving block squeezes the second wedge block, causing the reinforcing nail to be driven into the hole wall. At the same time, the side nail is linked with the moving block through the connecting rod. Under the action of the moving block, the angle is adjusted and it is driven into the hole wall, forming multi-directional reinforcement, which effectively improves the bonding strength between the anti-slide pile and the hole wall.

[0025] Compared with existing technologies, this anti-slide pile based on deep trench terrain and manually excavated holes can ensure the convenience of installation through the snap-fit ​​assembly, the cooperation between the first wedge block and the snap-fit ​​groove, and the elastic effect of the first spring.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Example 1 like Figures 1 to 6The method for constructing anti-slide piles based on deep trench terrain and intelligent monitoring includes a mounting base 1, a connecting frame 2 attached to the mounting base 1, and a connecting component 3 connecting the connecting frame 2 to the mounting base 1. The connecting frames 2 are connected to each other and to the mounting base 1 by the connecting component 3, facilitating the connection between the connecting frame 2 and the mounting base 1, or between multiple connecting frames 2. The mounting base 1 and the connecting frame 2 are provided with a reinforcing component 4 that can be driven into the inner wall of the hole where the anti-slide pile is placed, which can reinforce the structure in multiple directions and further improve the connection strength between the anti-slide pile and the hole wall. The mounting base 1 and the connecting frame 2 are provided with a fixing groove 5, and the fixing groove 5 is provided with connecting grooves 6 on both sides. The connecting frame 2 is provided with a connecting groove 7.

[0030] In a preferred embodiment, the snap-fit ​​assembly 3 includes a first wedge block 301, which is slidably snapped onto the connecting groove 6. The other end of the first wedge block 301 is provided with a first spring 302, which is fixedly connected to the connecting groove 6. The first wedge block 301 is snapped into the snap-fit ​​groove 7, and the connecting frame 2 is snapped into the mounting base 1. When the first wedge block 301 moves, the first spring 302 is compressed. The connecting frame 2 is aligned with the fixing groove 5 on the mounting base 1. During the downward docking process of the connecting frame 2, the bottom of the connecting frame 2 will squeeze the first wedge block 301 in the connecting groove 6 of the mounting base 1, causing the first wedge block 301 to slide along the connecting groove 6 and compress the first spring 302. When the snap-fit ​​groove 7 on the connecting frame 2 is aligned with the connecting groove 6, the first spring 302 resets and pushes the first wedge block 301 into the snap-fit ​​groove 7, thus completing the stable snap-fit ​​between the connecting frame 2 and the mounting base 1.

[0031] In a preferred embodiment, the reinforcement component 4 includes a threaded rod 401, a reinforcing nail 402, and a side nail 404. The threaded rod 401 is rotatably mounted on the mounting bracket and the connecting bracket 2. The reinforcing nail 402 is connected to the connecting bracket 2 and the mounting base 1. The side nail 404 is rotatably mounted on the connecting bracket 2 and the mounting base 1. A second wedge block 403 is provided on the reinforcing nail 402, and the threaded rod 401 is located between the second wedge blocks 403. A second spring 405 is sleeved on the reinforcing nail 402. One end of the second spring 405 is fixedly connected to the mounting base 1 or the connecting bracket 2, and the other end of the second spring 405 is fixedly connected to the second wedge block 403. The second wedge block 403 can be moved... The reinforcing nail 402 moves, adjusting the second wedge block 403. A moving block 406 is threadedly connected to the threaded rod 401. The upper end of the moving block 406 is conical, and the moving block 406 is located between the second wedge blocks 403. The threaded rod 401 rotates, adjusting the position of the moving block 406. A connecting rod 407 is hinged to the moving block 406, and the connecting rod 407 is hinged to the side nail 404. The connecting rod 407 can limit the movement of the moving block 406. The moving block 406 is provided with a hinge seat 408, and the moving block 406 and the connecting rod 407 are hinged through the hinge seat 408. The movement of the moving block 406 facilitates the folding of the connecting rod 407 and the adjustment of the side nail. At the position of nail 404, the upper end of the threaded rod 401 is provided with a positioning groove 409, and the other end of the threaded rod 401 is provided with a connecting block 410. The connecting block 410 matches the positioning groove 409. Through the positioning groove 409 and the connecting block 410, the threaded rod 401 between the reinforcing components 4 is connected. The mounting base 1 and the connecting frame 2 are provided with reinforcing rods 8 arranged in an array to strengthen the stability of the mounting base 1 and the connecting frame 2. The bottom of the mounting base 1 is provided with an anti-slip pad 9, which can increase the friction between the mounting base 1 and the hole. When the threaded rod 401 rotates, it drives the threaded connecting moving block 406 to move axially. Since the upper end of the moving block 406 is conical and located at the first Between the two wedge blocks 403, the movement of the moving block 406 will squeeze the second wedge blocks 403 on both sides, causing the second wedge blocks 403 to move in a direction perpendicular to the threaded rod 401, thereby pushing the reinforcing nail 402 to extend towards the inner wall of the pile hole and penetrate into the rock and soil of the hole wall. At the same time, the movement of the second wedge blocks 403 will stretch the second spring 405 sleeved on the reinforcing nail 402. During the movement of the moving block 406, the connecting rod 407 on its hinge seat 408 will unfold or fold accordingly, causing the side nail 404 to rotate around the hinge point with the connecting frame 2 or the mounting base 1, so that the side nail 404 penetrates into the hole wall at an inclined angle, forming a multi-directional reinforcement structure of "vertical reinforcing nail 402 + inclined side nail 404", which further improves the connection strength between the anti-slide pile and the hole wall.

[0032] Example 2 The intelligent monitoring construction method for manually excavated anti-slide piles based on deep trench terrain includes the following steps: S1: Determine the pile location, hole depth and pile diameter using ground radar and total station, excavate the hole to a depth of 1m, clean the soil at the bottom of the hole, install steel formwork with a verticality deviation of ≤0.5%, and tie the reinforcing bars. Generally, the lap length of the main reinforcement is ≥30d. Pour the retaining wall concrete with a layer thickness of 20~30cm, and cure until the strength meets the standard. Repeat the above operations until the designed hole depth is reached. Mark the installation reference point, and then install the base 1 and connecting frame 2 to arrange strain, displacement, torque and tilt sensors. Connect the intelligent terminal, input the early warning threshold, and calibrate the sensor zero point and torque. S2: Level the bottom of the deep trench, lay anti-slip mat 9, use a jack to level the installation base 1, temporarily fix the installation base 1 with expansion bolts, and check the elevation and levelness of the top surface, where the elevation error of the top surface is ±10mm; S3: The hoisting connecting frame 2 is placed above the mounting base 1. The first spring 302 pushes the wedge block into the connecting groove 6. The displacement sensor monitors the clamping gap. The reinforcing nail 402 and side nail 404 are screwed into the hole wall to monitor the torque and anchoring force. S4: Concrete is poured through a chute, ensuring a slump of 8-10cm, controlling the burial depth of the guide pipe to 2-6m, and the initial pouring volume ≥1.2m³. S5: Drip irrigation for moisturizing and maintenance, water flow rate is 2L / h, monitor intensity for 7 days, temperature and humidity sensor monitoring, generate 7-day maintenance report, and check displacement, stress, and pile strength.

[0033] The working process of this application is as follows: Based on the specific geological conditions of the deep ditch terrain and the design requirements of the anti-slide piles, it is first necessary to accurately measure the depth and diameter parameters of the pile hole. Based on this, the required reasonable combination quantity of the mounting base 1 and connecting frame 2 is calculated. After determining the quantity, professional hoisting equipment is used to slowly lift the mounting base 1 to the bottom of the pile hole. During this process, special attention must be paid to controlling the descent speed to ensure that the mounting base 1 is stably positioned. The anti-slip pad 9 at the bottom of the mounting base 1 is made of a high-friction coefficient material. When the base contacts the bottom of the hole, the anti-slip pad 9 can effectively increase the contact friction with the soil layer at the bottom of the hole, thereby achieving initial fixation of the mounting base 1. This design is particularly suitable for situations where there may be a slight slope or loose soil layer at the bottom of the deep ditch. To effectively prevent the base from sliding due to external forces, after positioning the mounting base 1, the splicing of the connecting frame 2 begins. The first connecting frame 2 is precisely aligned with the pre-set fixing groove 5 on the mounting base 1. As the connecting frame 2 moves downwards vertically, its bottom gradually presses against the first wedge block 301 installed in the connecting groove 6 of the base. This pressing action causes the first wedge block 301 to slide smoothly along the guide track of the connecting groove 6, while simultaneously compressing the first spring 302 pre-installed in the groove. When the connecting frame 2 continues to move downwards until its locking groove 7 is completely aligned with the connecting groove 6, the compressed first spring 302 immediately releases its elastic potential energy, pushing the first wedge block 301 to quickly engage in the locking groove 7, thus forming a strong mechanical connection. The connection ensures a stable connection between the connecting frame 2 and the mounting base 1. If the pile hole depth is large and needs to be extended, simply follow the same operating procedure and use the quick connection mechanism of the snap-fit ​​component 3 to connect the subsequent connecting frame 2 units in sequence. Throughout the splicing process, the evenly distributed array of reinforcing rods 8 on the mounting base 1 and each connecting frame 2 plays a crucial role. These reinforcing rods 8 are made of high-strength steel, and their optimized arrangement significantly improves the overall structure's resistance to bending and deformation, effectively preventing damage to the main structure of the anti-slide pile that may be caused by complex soil and rock pressure in deep trench areas. After completing the splicing of the main structure of the anti-slide pile, a critical reinforcement operation is required. The operator needs to rotate the threaded rod 401 set in the reinforcement component 4. When 401 rotates, the movable block 406, which is paired with it, moves smoothly along the axial direction through the threaded drive. Because the upper end of the movable block 406 is designed with a special conical structure and is precisely positioned between the two second wedge blocks 403, its axial movement generates a radial force, continuously compressing the second wedge blocks 403 on both sides. This compression forces the second wedge blocks 403 to move outwards in a direction perpendicular to the axis of the threaded rod 401, thereby pushing the reinforcing nail 402 connected to it to extend stably towards the inner wall of the pile hole until the tip of the reinforcing nail 402 is firmly embedded in the soil and rock of the hole wall. Simultaneously, the movement of the second wedge blocks 403 also stretches the second spring 405 sleeved on the reinforcing nail 402. This spring can play a role in buffering and maintaining tension during subsequent operations.Of particular note is that during the movement of the movable block 406, the connecting rod 407 on its top hinge seat 408 will unfold or fold accordingly. This linkage mechanism drives the side nail 404 to rotate precisely around its hinge point with the connecting frame 2 or the mounting base 1, allowing the side nail 404 to penetrate the borehole wall rock layer at the optimal tilt angle. This forms a unique multi-directional three-dimensional reinforcement system combining "vertical reinforcing nail 402 and oblique side nail 404." Through the synergistic effect of anchoring forces in different directions, the overall connection strength between the anti-slide pile and the borehole wall rock and soil is significantly improved, ensuring good support performance even under complex geological conditions. The intelligent monitoring and construction method for manually excavated anti-slide piles based on deep trench terrain allows for scientific and reasonable monitoring of the construction, improving construction quality.
