Description

Technical Field

[0001] This invention relates to the field of slope or incline stabilization technology, and in particular to slope repair equipment and its application method for deep foundation pit dewatering projects. Background Technology

[0002] The stability of foundation pit slopes directly affects project safety. Currently, slope compaction mainly relies on repeated pressing of the slope with excavator buckets. This method involves small working areas per operation, is time-consuming and labor-intensive, and places high demands on workers. The pressing pressure is difficult to control, easily causing pits on the slope surface, which weakens the soil structure. Furthermore, slope repair and vegetation protection are implemented in separate steps: after slope repair, seeds need to be manually scattered, but exposed seeds are easily washed away by rainwater and have difficulty taking root and stabilizing the soil. This separate operation leads to two problems: first, if vegetation is not promptly applied after soil compaction, topsoil erosion is exacerbated by rainfall; second, seeds cannot effectively embed themselves in the soil, reducing the soil's moisture retention capacity, which contradicts the soil stabilization and moisture retention requirements of water-conserving mining. To address these problems, this invention proposes a slope repair device for foundation pit dewatering projects and its application method. Summary of the Invention

[0003] This invention addresses the problems of low compaction efficiency, easy formation of pits and depressions, and seed separation and easy loss in existing slope repair methods. Combining the needs of water-conserving mining for slope stabilization and moisture retention, it proposes a slope repair device and its application method for deep foundation pit dewatering projects.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The slope stability repair equipment for deep foundation pit dewatering projects includes an upper base, a lower base, and a movable base. The movable base is located between the upper base and the lower base. Multiple sliding rods slide through the movable base, and one end of each sliding rod is provided with the same pressing plate for slope repair.

[0006] In order to enable the movable seat to reciprocate between the upper base and the lower base for slope trimming, a drive structure is provided between the upper base and the lower base. The drive structure includes two rotating shafts, a reciprocating lead screw between the upper base and the lower base, and two limiting slide rods.

[0007] The driving structure also includes a pressing structure for driving the pressing plate to reciprocate linearly to press the soil. The pressing structure includes a rotating cylinder rotating inside the moving seat and a transmission shaft rotating on the top of the moving seat. Both ends of the transmission shaft are fixed with rotating discs.

[0008] In one possible design, the drive structure further includes two bases, which are respectively bolted to the bottom of an upper base and a lower base for supporting the upper and lower bases. Two rotating shafts are rotatably connected within the upper and lower bases, respectively. Two first connecting sleeves are fixedly fitted onto the outer walls of each of the two rotating shafts. The two ends of the limiting slide rods extend slidably into the corresponding two first connecting sleeves, and one end of each limiting slide rod slides through a movable seat to limit its movement. First bolts are threaded onto each of the four first connecting sleeves, with one end of each bolt extending into the limiting slide rod to fix the limiting slide rod to the first connecting sleeve. Second connecting sleeves are fixedly fitted onto the outer walls of both rotating shafts, located between two first connecting sleeves on the same rotating shaft, with the two second connecting sleeves abutting against each other. Each of the two rotating cylinders is rotatably connected to one side of the reciprocating screw. Both ends of the reciprocating screw slide into the corresponding rotating cylinders. One end of the reciprocating screw is threaded through the moving seat. The rotating cylinder drives the reciprocating screw to rotate and move the moving seat. This is used for later pressing the plate to trim different positions of the slope. Both rotating cylinders are threaded with second bolts. One end of the second bolt extends into the reciprocating screw and is used to fix the rotating cylinder and the reciprocating screw together. The upper base and the lower base are placed at the top and bottom of the slope, respectively. The two ends of the limiting slide rod and the reciprocating screw are inserted into the corresponding first connecting sleeve and rotating cylinder, respectively. Then, the limiting slide rod and the reciprocating screw are fixed by the first bolt and the second bolt. Later, the motor in the second connecting sleeve drives the rotating cylinder and the reciprocating screw to rotate, which can drive the moving seat to move back and forth along the axis of the reciprocating screw to trim different positions of the slope.

[0009] In one possible design, the pressing structure further includes a rectangular groove within a movable seat. The rotating cylinder rotates within this groove and is slidably mounted on the outer wall of a reciprocating screw via a sliding block. A first gear is fixedly mounted on the outer wall of the rotating cylinder, and the reciprocating screw drives the first gear to rotate via the rotating cylinder. Two U-shaped frames are welded to the top of the movable seat, and one end of a drive shaft rotatably passes through both U-shaped frames. A second gear, meshing with the first gear, is fixedly mounted on the outer wall of the drive shaft and is located between the two U-shaped frames. The engagement of the first and second gear drives the drive shaft and the rotating disk to rotate. A single pressure plate is fixed to the top of multiple sliding rods, and a clearance groove is provided within the pressure plate. The top of the rotating disk extends into the clearance groove, and pins are fixed to the opposite sides of the two rotating disks. The inner walls of the two mutually spaced relief grooves are provided with sliding grooves. The sliding grooves cooperate with the pins to drive the pressure plate to move up and down reciprocally. In order to scatter seeds while the pressing plate is trimming the slope, two sets of sowing structures are provided in the moving seat. The sowing structure includes a storage cavity set in the moving seat and a connecting rod fixed to the top of the pressing plate. The rotating cylinder drives the reciprocating screw to rotate. The reciprocating screw drives the moving seat to move back and forth along the axis of the limiting slide rod. In addition, when the reciprocating screw rotates, the reciprocating screw drives the first gear to rotate through the rotating cylinder. The first gear drives the two rotating disks to rotate through the second gear and the transmission shaft. The rotating disks drive the pin to rotate. The cooperation between the pin and the sliding groove drives the pressure plate to move back and forth linearly. The pressure plate continuously presses the slope through the cooperation of the sliding rod, the round rod and the spring, compacting the soil and completing the slope trimming.

[0010] In one possible design, the sowing structure further includes a piston plate that slides and seals within the storage cavity. The top end of the connecting rod extends and seals into the storage cavity and is fixedly connected to the bottom of the piston plate. A pressing plate drives the piston plate to reciprocate via the connecting rod. Multiple discharge ports are provided on one side of the storage cavity, cooperating with the piston plate. The piston plate moves below the discharge ports to discharge seeds to the outside. A placement plate is fixed on one side of the movable seat to hold the seeds discharged from the discharge ports. Multiple air vents are provided on one side of the inner wall of the storage cavity. When the piston plate moves down and closes the discharge ports, air in the storage cavity is blown through the air vents onto the seeds placed on the placement plate. The storage cavity is equipped with a sealing mechanism for sealing the storage cavity. The cover; the pressing plate pushes the piston plate to move synchronously through the connecting rod. When the piston plate moves down, the seeds above the piston plate fall onto the placement plate through the discharge port. When the piston plate moves up, the seed discharge is released, and the piston plate draws outside air into the storage chamber through the one-way valve. When the piston plate moves down again and the discharge port is blocked, the piston plate releases the gas in the storage chamber to the outside through the air outlet. The released gas can blow the seeds on the placement plate to one side, thus enabling the seeds to be scattered during the slope trimming process. In addition, when the pressing plate presses the soil later, it can press the seeds into the soil, preventing the seeds from easily rolling off the slope. When the pressing plate compacts the soil, it presses the seeds in simultaneously, forming a water-retaining layer to meet the soil stabilization requirements for water-retaining mining.

[0011] In one possible design, the bottom inner wall of the storage cavity is provided with a through hole, and a one-way valve is fixed in the through hole. When the piston plate moves back and forth, it draws outside air into the storage cavity and discharges it through the air outlet for scattering the seeds.

[0012] In one possible design, multiple air outlets correspond to and are located below multiple material outlets, for use to allow air gushing from the air outlets to scatter the seeds on the placement plate.

[0013] In one possible design, the top of the pressing plate is fixed with multiple round rods, the top ends of which slide into corresponding sliding rods. The top ends of the multiple round rods are fixed with springs, and the top ends of the multiple springs are fixedly connected to the inner wall of the top of the sliding rods. When the sliding rods drive the pressing plate to move back and forth to trim the slope, the cooperation between the round rods and the springs can make way for the movement of the sliding rods.

[0014] In one possible design, the base has multiple storage slots at its bottom, each of which is slidably connected to a lifting plate. Each of the storage slots has an electric push rod fixed to its top inner wall. The output shaft of the electric push rod is fixedly connected to the top of the lifting plate to drive the lifting plate to move up and down. Each of the lifting plates has multiple casters fixed to its bottom to drive the base to move as a whole when the casters move out of the storage slots, making it easy to move the base to the appropriate position for slope trimming.

[0015] In one possible design, the bottom of the pressing plate is fixed with multiple trapezoidal templates to form ditches on the slope when the pressing plate is used for slope trimming, so as to facilitate drainage of the slope in the later stage.

[0016] The method of using slope repair equipment for deep foundation pit dewatering projects includes the following steps:

[0017] S1. Place the upper base and the lower base at the top and bottom of the slope respectively, insert the limiting slide rod and the reciprocating screw into the corresponding first connecting sleeve and rotating sleeve, and fix them by the first bolt and the second bolt.

[0018] S2. Start the motor in the second connecting sleeve to drive the rotating cylinder, which in turn drives the reciprocating screw to rotate and drives the moving seat to move back and forth along the limit slide rod. At the same time, the reciprocating screw drives the rotating disk to rotate through the rotating cylinder, the first gear, the second gear, and the transmission shaft. The pin and the sliding groove work together to push the pressure plate to move back and forth in a linear motion, which works with the sliding rod, the round rod, and the spring to compact the soil. The trapezoidal template forms grooves during the pressing process. After continuous trimming, the grooves are connected to form a ditch.

[0019] S3. When the pressing plate moves back and forth, it pushes the piston plate to move synchronously through the connecting rod; when it moves down, the seeds fall onto the placement plate through the discharge port; when it moves up, the one-way valve draws in air into the storage chamber; when it moves down again, the gas blows the seeds through the air outlet, and with the subsequent pressing, embeds the seeds into the soil to prevent them from rolling off.

[0020] S4. After the repair is completed, the electric push rod pushes the lifting plate and the moving wheels to move down, lifting the base and realizing the overall movement of the equipment. No manual operation is required, which improves efficiency and avoids slope potholes.

[0021] Beneficial effects: In this invention, the rotating cylinder is slidably sleeved on the outer wall of the reciprocating screw, the outer wall of the rotating cylinder is fixedly sleeved with a first gear, the outer wall of the transmission shaft is fixedly sleeved with a second gear, both ends of the transmission shaft are fixed with rotating disks, and pins are fixed on the opposite sides of the two rotating disks. The inner walls of the opposite sides of the clearance groove are provided with sliding grooves. The reciprocating screw drives the first gear to rotate through the rotating cylinder, and the first gear drives the rotating disk to rotate through the second gear. The cooperation between the pin and the sliding groove drives the pressure plate to move reciprocally in a linear fashion. The pressure plate continuously presses the slope through the cooperation of the sliding rod, the round rod, and the spring, automatically completing the slope trimming operation, and maintaining a consistent pressure on the slope to avoid the formation of potholes.

[0022] In this invention, a piston plate is sealed and slidably installed inside the storage cavity. The top end of the connecting rod is fixedly connected to the bottom of the piston plate. Multiple discharge ports are provided on one side of the storage cavity, and a placement plate is fixed on one side of the movable seat. Multiple air outlets are provided on the inner wall of one side of the storage cavity. When the piston plate moves down, the seeds fall onto the placement plate through the discharge ports. When the piston plate moves up, it draws outside air into the storage cavity. When the piston plate moves down again, the gas in the storage cavity is discharged to the outside through the air outlets. The discharged gas can blow the seeds on the placement plate to one side, thereby enabling the seeds to be scattered during the slope trimming process. Furthermore, when the pressing plate presses the soil later, it can press the seeds into the soil, preventing the seeds from easily rolling off the slope.

[0023] In this invention, two first connecting sleeves are fixedly fitted on the outer walls of the two rotating shafts. The two ends of the limiting slide rod slide into the corresponding two first connecting sleeves respectively. A second connecting sleeve is fixedly fitted on the outer walls of the two rotating shafts. A rotating sleeve is rotatably connected to one side of the two second connecting sleeves that are close to each other. The two ends of the reciprocating screw slide into the corresponding rotating sleeve respectively. The rotating sleeve and the reciprocating screw are driven to rotate by the motor in the second connecting sleeve, which can drive the moving seat to move back and forth along the axis of the reciprocating screw. The rotation of the reciprocating screw can also drive the pressing plate to press the slope back and forth, thereby automatically trimming the slope.

[0024] In this invention, the moving seat is driven to move back and forth by the reciprocating screw rotation. When the moving seat moves, it can not only trim the slope by pressing the plate, but also automatically scatter the seeds. The scattered seeds are then pressed into the soil by the pressing plate to prevent the seeds from rolling off the slope, which facilitates the later germination of the seeds and reinforces the slope.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Example 1: Refer to Figure 1 , Figure 2 and Figure 6 This slope-repairing equipment relates to the field of building construction technology. It is a slope-repairing device for deep foundation pit dewatering projects, mainly composed of an upper base 1 (45 steel quenched (HRC45-50)), a lower base 2 (45 steel quenched (HRC45-50)), and a movable base 16 located between the upper base 1 and the lower base 2. Multiple sliding rods 17 slide through the movable base 16, and one end of each sliding rod 17 is connected to a pressing plate 21 for slope adjustment. A drive structure is provided to enable the reciprocating movement of the movable base 16 between the upper base 1 and the lower base 2.

[0040] Reference Figure 1 and Figure 2 The drive structure includes two bases 3, which are bolted to the bottom of the upper base 1 and the lower base 2 respectively, for supporting the upper base 1 and the lower base 2. Two rotating shafts 8 are rotatably connected inside the upper base 1 and the lower base 2 respectively, and two first connecting sleeves 9 are fixedly sleeved on the outer walls of the two rotating shafts 8. The two ends of the two limiting slide rods 11 slide into the corresponding two first connecting sleeves 9 respectively, and one end of the two limiting slide rods 11 slides through the moving seat 16 to limit the movement of the moving seat 16. The four first connecting sleeves 9 are each threaded with a first bolt 13, one end of the first bolt 13 extends into the limiting slide rod 11, for fixing the limiting slide rod 11 to the first connecting sleeve 9.

[0041] Reference Figure 1 , Figure 2 and Figure 5 Each of the two rotating shafts 8 has a second connecting sleeve 10 fixedly fitted on its outer wall. The second connecting sleeve 10 is located between two first connecting sleeves 9 on the same rotating shaft 8. A rotating sleeve 14 is rotatably connected to the side of each of the two second connecting sleeves 10 that is close to each other. The two ends of a reciprocating screw 12 (nitrided with 38CrMoAlA (HV≥800)) slide into the corresponding rotating sleeve 14. One end of the reciprocating screw 12 passes through a movable seat 16 and is screwed into the movable seat 16. The rotating sleeve 14 drives the reciprocating screw 12 to rotate, which in turn drives the movable seat 16 to move, for later use by pressing the pressure plate 21 to trim different positions of the slope. A second bolt 15 is threaded into each of the two rotating sleeves 14. One end of the second bolt 15 extends into the reciprocating screw 12, for fixing the rotating sleeve 14 to the reciprocating screw 12.

[0042] Specifically, the upper base 1 and lower base 2 are placed at the top and bottom of the slope, respectively. The ends of the limiting slide rod 11 and the reciprocating screw 12 are inserted into the corresponding first connecting sleeve 9 and rotating cylinder 14, respectively. Then, the limiting slide rod 11 and the reciprocating screw 12 are fixed using the first bolt 13 and the second bolt 15. The motor inside the second connecting sleeve 10 is started (the specific installation position and driving method of the motor can be designed according to actual conditions, such as driving the rotating cylinder 14 through a chain, belt, or other transmission method, and it can be a worm gear reducer motor), driving the rotating cylinder 14 and the reciprocating screw 12 to rotate. The rotation of the reciprocating screw 12 drives the moving seat 16 to move back and forth along the axis of the reciprocating screw 12, adjusting different positions on the slope.

[0043] In addition, the drive structure includes a pressing structure for driving the pressing plate 21 to reciprocate linearly to press the soil. Simultaneously, to allow for seed dispersal while the pressing plate 21 is shaping the slope, the equipment also includes two sets of sowing structures.

[0044] Reference Figures 6-9The pressing structure includes a rotating cylinder 23 that rotates within a rectangular groove 22 in the movable seat 16. The rotating cylinder 23 is slidably mounted on the outer wall of the reciprocating screw 12 via a sliding block. A first gear 24 is fixedly mounted on the outer wall of the rotating cylinder 23, and the reciprocating screw 12 drives the first gear 24 to rotate via the rotating cylinder 23. Two U-shaped frames 25 are welded and fixed to the top of the movable seat 16. One end of a drive shaft 26 rotatably passes through the two U-shaped frames 25. A second gear 27 that meshes with the first gear 24 is fixedly mounted on the outer wall of the drive shaft 26, and the second gear 27 is located between the two U-shaped frames 25. The engagement of the first gear 24 and the second gear 27 drives the drive shaft 26 and the rotating disk 29 to rotate. The tops of multiple sliding rods 17 are fixed to the same pressure plate 18, which has a clearance groove 28. The top of the rotating disk 29 extends into the clearance groove 28. Pins 30 are fixed on the opposite sides of the two rotating disks 29. Sliding grooves 31 are provided on the inner walls of the opposite sides of the clearance grooves 28. The sliding grooves 31 cooperate with the pins 30 to drive the pressure plate 18 to move up and down reciprocally.

[0045] Specifically, when the reciprocating screw 12 rotates, it drives the first gear 24 to rotate via the rotating cylinder 23. The first gear 24, through the second gear 27 and the transmission shaft 26, drives the two rotating disks 29 to rotate. The rotating disks 29 drive the pin 30 to rotate, and the engagement of the pin 30 with the sliding groove 31 drives the pressure plate 18 to move reciprocally in a linear motion. The pressure plate 18, through the engagement of the sliding rod 17, the round rod 19, and the spring 20, drives the pressing plate 21 to continuously press the slope, compacting the soil and completing the slope trimming.

[0046] Reference Figure 10 and Figure 11The seeding structure is an important component of slope stabilization equipment in deep foundation pit dewatering projects, and it includes a storage chamber 32. The storage chamber 32 serves as the seed storage space, and a piston plate 34 is slidably and sealed within it. A U-shaped polytetrafluoroethylene (PTFE) sealing strip (compression rate 18%) is installed on the edge of the piston plate 34. The piston plate 34 can reciprocate up and down within the storage chamber 32. A connecting rod 35 is fixed to the top of a pressing plate 21. The top of the connecting rod 35 extends slidably into the storage chamber 32 and is fixedly connected to the bottom of the piston plate 34. When the pressing plate 21 is subjected to external force, it drives the piston plate 34 to reciprocate via the connecting rod 35. This connection method allows the operation of the pressing plate 21 to be directly converted into the movement of the piston plate 34 within the storage chamber 32, providing the power basis for subsequent seed discharge and airflow. Multiple discharge ports 36 are provided on one side of the storage chamber 32, and these discharge ports 36 cooperate with the piston plate 34. When the piston plate 34 moves below the discharge port 36, the seeds in the storage chamber 32 can be discharged to the outside through the discharge port 36. This design cleverly utilizes the positional change of the piston plate 34 to control the discharge of seeds, achieving effective control over the amount of seeds discharged.

[0047] Reference Figure 10 and Figure 11 A placement plate 37 is fixedly installed on one side of the movable seat 16. The main function of the placement plate 37 is to place the seeds discharged from the discharge port 36. When the seeds are discharged from the storage chamber 32 through the discharge port 36, they will fall directly onto the placement plate 37, providing a temporary storage location for subsequent seed scattering.

[0048] Reference Figure 11 The storage chamber 32 has multiple air outlets 40 on one inner wall, and these outlets 40 correspond to and are located below multiple discharge outlets 36. When the piston plate 34 moves down and closes the discharge outlets 36, the air in the storage chamber 32 is blown through the air outlets 40 onto the seeds placed on the placement plate 37. This design allows the air in the storage chamber 32 to be used to scatter the seeds while the piston plate 34 moves down to close the discharge outlets 36, thus improving the seed sowing efficiency.

[0049] Reference Figure 10 A cover 33 is provided inside the storage cavity 32 for sealing the storage cavity 32. The function of the cover 33 is to prevent the seeds from leaking out of the storage cavity 32 during storage and transportation, and also to prevent external impurities from entering the storage cavity 32 and affecting the quality of the seeds.

[0050] Specifically, the pressing plate 21 pushes the piston plate 34 to move synchronously via the connecting rod 35. When the piston plate 34 moves downward, the seeds above it fall onto the placement plate 37 through the discharge port 36, thus discharging the seeds. When the piston plate 34 moves upward, it releases the seeds, and simultaneously draws outside air into the storage chamber 32 through the one-way valve 39. This design ensures that during the reciprocating movement of the piston plate 34, both seed discharge and the necessary air supply for subsequent airflow are achieved.

[0051] Reference Figure 10 and Figure 11 The bottom inner wall of the storage cavity 32 is provided with a through hole 38, and a one-way valve 39 is fixed in the through hole 38.

[0052] Specifically, as the piston plate 34 reciprocates, outside air is drawn into the storage chamber 32 through the one-way valve 39 and discharged through the air outlet 40. When the piston plate 34 moves downward again, during the process of sealing the discharge port 36, the piston plate 34 will discharge the gas in the storage chamber 32 to the outside through the air outlet 40. Since the multiple air outlets 40 correspond to and are located below the multiple discharge ports 36, the air gushing out from the air outlets 40 can blow the seeds on the placement plate 37 to one side, thereby enabling the seeds to be scattered during the slope trimming process.

[0053] Later, when the pressing plate 21 presses down on the soil, since the seeds have already been scattered on the slope and some seeds may have already made contact with the soil, the pressing action of the pressing plate 21 can further press the seeds into the soil, preventing the seeds from easily rolling off the slope. This design improves the seed survival rate and the stability of the slope.

[0054] Through the above description of specific implementation methods, it can be clearly seen how the seeding structure of the slope stability repair equipment for this deep foundation pit dewatering project achieves the functions of seed storage, release, scattering, and pressing into the soil. This design has the advantages of simple structure, convenient operation, and high seeding efficiency, and can effectively improve slope stability and ecological restoration effects. It is feasible and operable.

[0055] Reference Figure 6 Multiple round rods 19 are fixed to the top of the pressing plate 21. The number of round rods 19 can be set according to actual needs, for example, four round rods 19 are evenly distributed around the top of the pressing plate 21. The number of sliding rods 17 corresponds to the number of round rods 19, and the top of each round rod 19 slides into the corresponding sliding rod 17. A spring 20 is fixed to the top of each of the multiple round rods 19. The number of springs 20 is the same as the number of round rods 19, and the top of each of the multiple springs 20 is fixedly connected to the top inner wall of the sliding rod 17.

[0056] Specifically, when the sliding rod 17 drives the pressing plate 21 to reciprocate and perform slope trimming operations, if the slope surface is uneven or there are obstacles, the round rod 19 will slide inside the sliding rod 17. Since the two ends of the spring 20 are fixedly connected to the top of the round rod 19 and the inner wall of the top of the sliding rod 17, the round rod 19 will compress the spring 20 when it slides. The elastic deformation of the spring 20 can make way for the movement of the sliding rod 17, avoiding damage to the sliding rod 17 or the pressing plate 21 due to the condition of the slope surface, while ensuring that the trimming operation can continue.

[0057] The combination of the round rod 19 and the spring 20 enables the slope repair equipment to adapt flexibly to complex slope surfaces, reducing the risk of equipment damage and improving the stability and continuity of the repair operation.

[0058] Reference Figure 2 and Figure 3 The base 3 has multiple storage slots 4 at its bottom. The number of storage slots 4 can be determined according to the overall size of the equipment and the need for movement. For example, four storage slots 4 can be set, located at the four corners of the bottom of the base 3. A lifting plate 5 is slidably connected inside each of the multiple storage slots 4. An electric push rod 6 is fixed to the top inner wall of each of the multiple storage slots 4. The output shaft of the electric push rod 6 is fixedly connected to the top of the lifting plate 5 to drive the lifting plate 5 to rise and fall. Multiple casters 7 are fixed to the bottom of each of the multiple lifting plates 5, for example, four casters 7 are fixed to the bottom of each lifting plate 5.

[0059] Specifically, when the movable base 16 needs to be moved to the appropriate position for slope trimming, the electric push rod 6 is activated. The output shaft of the electric push rod 6 extends, pushing the lifting plate 5 to slide downwards within the storage groove 4, causing the moving wheels 7 to move out of the storage groove 4. After the moving wheels 7 contact the ground, the rolling motion of the moving wheels 7 drives the entire base 3 to move. When the equipment moves to the designated position, the output shaft of the electric push rod 6 retracts, causing the lifting plate 5 to slide upwards within the storage groove 4, retracting the moving wheels 7 back into the storage groove 4, ensuring stable contact between the bottom of the base 3 and the ground, thus guaranteeing the stability of the equipment during the trimming operation.

[0060] By setting up adjustable casters 7, the equipment can be moved to a designated location quickly and easily when it needs to be moved; during maintenance work, the casters 7 can be retracted to ensure stable placement of the equipment, thereby improving the quality and safety of the maintenance work.

[0061] Example 2: Reference Figure 12 Improvements based on Example 1: Multiple trapezoidal templates 41 are detachably fixed to the bottom of the pressing plate 21. Trapezoidal templates 41 of different heights can be selected as needed. The number and shape of trapezoidal templates 41 can be designed according to the drainage requirements of the slope. For example, multiple trapezoidal templates 41 are arranged at equal intervals. The size and spacing of the trapezoidal templates 41 can be determined according to the actual drainage requirements.

[0062] Specifically, during slope trimming using the pressing plate 21, as the pressing plate 21 compresses and trims the slope soil, the trapezoidal template 41 moves along with the pressing plate 21, forming a ditch on the slope. The shape and size of the trapezoidal template 41 determine the shape and depth of the ditch. By rationally designing the trapezoidal template 41, the formed ditch can meet the slope drainage requirements.

[0063] By setting a trapezoidal template 41 at the bottom of the pressing plate 21, a ditch can be easily and quickly formed on the slope while trimming the slope, which facilitates drainage of the slope in the later stage and improves the stability and safety of the slope.

[0064] In summary, the slope stabilization repair equipment for the deep foundation pit dewatering project, through the specific implementation methods described above, effectively repairs the slope while ensuring the stability and operability of the equipment under different working conditions, thus possessing high practical value.

[0065] The method for using slope repair equipment for deep foundation pit dewatering projects includes the following steps:

[0066] S1. Place the upper base 1 and the lower base 2 at the top and bottom of the slope respectively. Insert the two ends of the limiting slide rod 11 and the reciprocating screw 12 into the corresponding first connecting sleeve 9 and rotating sleeve 14 respectively. Then fix the limiting slide rod 11 and the reciprocating screw 12 with the first bolt 13 and the second bolt 15.

[0067] S2. During slope trimming, the motor inside the second connecting sleeve 10 drives the rotating cylinder 14 to rotate. The rotating cylinder 14 drives the reciprocating screw 12 to rotate. The reciprocating screw 12 drives the moving seat 16 to reciprocate along the axis of the limiting slide rod 11. In addition, when the reciprocating screw 12 rotates, it drives the first gear 24 to rotate through the rotating cylinder 23. The first gear 24 drives the two rotating disks 29 to rotate through the second gear 27 and the transmission shaft 26. The rotating disks 29 drive the pin 30 to rotate. The pin 30 and the slide rod 26 rotate together. The moving groove 31 drives the pressure plate 18 to move back and forth in a straight line. The pressure plate 18 continuously presses the slope through the cooperation of the sliding rod 17, the round rod 19 and the spring 20, compacting the soil and completing the slope trimming. In addition, when the pressing plate 21 presses the slope back and forth, the trapezoidal template 41 can form grooves on the slope. When the pressing plate 21 completes the slope trimming, the grooves formed by the trapezoidal template 41 each time they are pressed connect to form a ditch. Concrete can be poured into the ditch later to facilitate drainage during the rainy season.

[0068] S3. Additionally, when the pressing plate 21 reciprocates to trim the slope, the pressing plate 21 pushes the piston plate 34 to move synchronously through the connecting rod 35. When the piston plate 34 moves down, the seeds above the piston plate 34 fall onto the placement plate 37 through the discharge port 36. When the piston plate 34 moves up, the seeds are released, and the piston plate 34 draws outside air into the storage chamber 32 through the one-way valve 39. When the piston plate 34 moves down again and blocks the discharge port 36, the piston plate 34 releases the gas in the storage chamber 32 to the outside through the air outlet 40. The released gas can blow the seeds on the placement plate 37 to one side, thus completing the seed scattering during the slope trimming process. Furthermore, when the pressing plate 21 presses the soil later, it can press the seeds into the soil, preventing the seeds from easily rolling off the slope.

[0069] S4. When the pressing plate 21 completes the slope trimming, the electric push rod 6 pushes the lifting plate 5 and the moving wheel 7 down until the moving wheel 7 lifts the base 3. At this time, the upper base 1, lower base 2 and moving seat 16 can be moved to one side through the base 3 to continue trimming the slope. No manual operation is required during the trimming process, which saves time and effort and avoids the occurrence of potholes on the slope during the trimming process.

[0070] However, as is well known to those skilled in the art, the working principle and wiring method of the electric actuator 6 are commonplace and are all conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0071] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
