Description

Technical Field

[0001] The utility model relates to a cast-in-place pile reinforcement structure, belonging to the technical field of building construction. Background Art

[0002] A bored pile is a type of pile made by drilling a hole in place and pouring concrete or reinforced concrete. During the construction process, a casing must first be inserted into the soil layer, followed by excavation. Because the soil quality varies at different construction sites, the casing can easily sink during construction when the soil is soft. This can affect the operation of drilling equipment, and the drilled hole can easily collapse due to the casing sinking, posing a certain risk to construction. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a cast-in-place pile reinforcement structure, which solves the problem in the prior art that the casing is prone to sinking when constructed in a site with soft soil. When a drilling device is used to drill a hole in the ground, the sinking of the casing will affect the operation of the drilling device, and the drilled hole is prone to collapse due to the sinking of the casing, which makes the construction risky.

[0004] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: A cast-in-place pile reinforcement structure includes a ground and a casing, one end of the casing is vertically inserted into the casing, and the other end of the casing is located outside the ground, and also includes an auxiliary support plate, a fixed support block, a sliding groove and a movable support block, the auxiliary support plate is sleeved on the end of the casing located outside the ground, the fixed support block is fixedly arranged on the outer curved surface of the casing close to the end away from the ground, two fixed support blocks are arranged side by side and there is a gap between the two fixed support blocks, the two fixed support blocks arranged side by side form a support structure, four support structures are arranged in an equiangular array in the circumferential direction of the casing, the sliding groove is opened on the side of the auxiliary support plate away from the ground, and the opening is vertically aligned with each fixed support block, the movable support block extends vertically and one end extends into the sliding groove, the movable support block is horizontally slidable with the sliding groove, a plug connector is fixed to the end of the movable support block away from the auxiliary support plate, and a plug slot is opened on the end of the fixed support block facing the auxiliary support plate, and the plug connector and the plug slot are plugged together along the sliding direction of the movable support block.

[0005] By adopting the above technical solution, after the casing is inserted into the ground, a certain length is left above the ground. At this time, the auxiliary support plate is inserted into the casing, and the fixed support block is vertically aligned with the movable support block, the end of the plug connector is aligned with the opening of the plug slot, and then the movable support block is pushed toward the casing. At this time, the plug connector gradually slides into the plug slot to plug the fixed support block into the movable support block. When the casing tends to sink, the casing applies downward pressure on the movable support block through the fixed support block. At this time, the movable support block transfers the downward pressure to the auxiliary support plate. Since the contact area between the auxiliary support plate and the ground is large, it is not easy to sink and has a supporting effect on the casing. At this time, it can be ensured that the casing does not sink during construction, which is conducive to improving construction safety.

[0006] The utility model is further configured as follows: a winding wheel is rotatably arranged between two adjacent movable support blocks located at the same group of support structures, an circumscribed shaft is coaxially fixedly arranged on the end of the winding wheel, an end of the circumscribed shaft away from the winding wheel passes through the movable support block and extends to the outside of the movable support block, a connecting rope is wound around the winding wheel, and an end of the connecting rope away from the winding wheel extends to the inside of the casing.

[0007] By adopting the above technical solution, the end of the circumscribed shaft away from the winding wheel can be connected to the external driving element, and the external driving element controls the rotation and stopping of the winding wheel through the circumscribed shaft, thereby controlling the length of the connecting rope wound on the winding wheel. The end of the connecting rope away from the winding wheel can be tied to the end of the steel cage of the bored pile away from the ground. At this time, the connecting rope can keep the steel cage stationary, and then the other end of the steel cage can be welded and fixed to the end of the bundled steel cage to complete the extension of the steel cage. The vertical position of the bundled steel cage can be adjusted according to the actual working conditions through the driving element, which is conducive to the rapid welding operation of the steel cage.

[0008] The utility model is further configured as follows: a lifting groove is provided on the inner wall of the casing along the axial direction of the casing, an inner receiving groove is provided on the side of the lifting groove close to the ground and inserted into the casing, an inclined surface is transitionally set between the inner receiving groove and the end wall of the lifting groove on the side away from the opening, a lifting block is provided in the lifting groove along the axial sliding of the casing, a movable abutment block is inserted in the lifting block, the movable abutment block slides radially along the casing in the lifting block, an elastic cavity is provided in the lifting block, a connecting block is fixed to the part of the movable abutment block located in the elastic cavity, the connecting block extends into the elastic cavity and slidably abuts against the inner wall of the elastic cavity, a tension spring is provided in the elastic cavity with the same elastic force direction as the sliding direction of the movable abutment block, and the two ends of the tension spring are respectively fixed to the connecting block and the inner wall of the elastic cavity.

[0009] By adopting the above technical solution, when the steel cage is lowered into the casing, the end of the steel cage can abut against the movable abutment block. At this time, the gravity of the steel cage is supported by the movable abutment block, and the connecting rope resists the load on the lifting block and the movable abutment block through tension, thereby maintaining the stability of the steel cage. As the driving element is driven, the extended length of the connecting rope inside the casing can be controlled, thereby controlling the position of the lifting block and the movable abutment block, and then controlling the position of the steel cage, so that the lower end of the steel cage can be stabilized during the process of the steel cage being hoisted, so that the steel cage as a whole is in a stable motion state, avoiding the steel cage When the lifting block is in a stable condition, it collides with the casing and damages the casing. When the lifting block moves to the position of the inner groove, the end of the movable abutment block away from the steel cage is aligned with the opening of the inner groove. At this time, the elastic action of the tension spring pulls the connecting block and the movable abutment block toward the inner groove. At this time, the abutting end of the movable abutment block and the steel cage retracts into the lifting block. At this time, the steel cage can continue to fall, and the lifting block can be pulled up by the connecting rope. During the pulling up process, the movable abutment block is pressed into the lifting block under the abutment of the end wall of the inner groove away from the opening, and then moves to the lifting groove and gradually returns to the starting position.

[0012] By adopting the above technical solution, during the movement of the connecting rope, the rotating shaft is rotated by holding the handle and turning the handle, thereby controlling the rotation of the clamping rotating wheel. When the outer convex end of the clamping rotating wheel moves away from the fixed block, the connecting rope can pass normally between the fixed block and the clamping rotating wheel. When the outer convex end of the clamping rotating wheel moves toward the fixed block, the anti-slip layer of the outer convex end of the fixed block and the extrusion effect formed between the outer convex end of the clamping rotating wheel and the fixed block work together to limit the movement of the connecting rope, thereby achieving the purpose of emergency braking of the connecting rope when the connecting rope moves too fast.

[0013] The utility model is further configured as follows: a pressure spring is provided on the side of the movable support block located in the sliding groove away from the casing, the elastic direction of the pressure spring is the same as the sliding direction of the movable support block, and the two ends of the pressure spring are respectively fixed to the movable support block and the inner wall of the sliding groove.

[0014] By adopting the above technical solution, the movable support block can maintain the connection with the fixed support block under the elastic action of the pressure spring, avoiding the movable support block and the fixed support block from being disconnected during use, thereby improving the stability of the reinforcement structure.

[0015] The beneficial effect of the utility model is that when the casing tends to sink, the casing applies downward pressure to the movable support block through the fixed support block. At this time, the movable support block transfers the downward pressure to the auxiliary support plate. Since the contact area between the auxiliary support plate and the ground is large, it is not easy to sink and has a supporting effect on the casing. At this time, it can ensure that the casing does not sink during the construction process, which is conducive to improving construction safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0024] like Figure 1-3 As shown, a cast-in-place pile reinforcement structure includes a ground 10 and a casing 11, one end of the casing 11 is vertically inserted into the casing 11, and the other end of the casing 11 is located outside the ground 10, wherein the direction of inserting the casing 11 into the ground 10 is downward, and the direction away from the ground 10 is upward. It also includes an auxiliary support plate 12, a fixed support block 13, a sliding groove 21 and a movable support block 20, the auxiliary support plate 12 is sleeved on the end of the casing 11 located outside the ground 10, the fixed support block 13 is fixedly arranged on the outer curved surface of the casing 11 close to the end away from the ground 10, two fixed support blocks 13 are arranged side by side, and there is a gap between the two fixed support blocks 13, and the two fixed support blocks 13 arranged side by side are spaced apart. The support block 13 forms a support structure, and four support structures are arranged in an equiangular array in the circumferential direction of the casing 11. The sliding groove 21 is opened on the side of the auxiliary support plate 12 away from the ground 10 and the opening is vertically aligned with each fixed support block 13. The extension direction of the sliding groove 21 is the same as the radial direction of the casing 11. The movable support block 20 extends vertically and one end extends into the sliding groove 21. The movable support block 20 and the sliding groove 21 are arranged to slide horizontally. A plug connector 22 is fixed to the end of the movable support block 20 away from the auxiliary support plate 12, and a plug connector 23 is opened on the end of the fixed support block 13 facing the auxiliary support plate 12. The plug connector 22 and the plug connector 23 are plugged in along the sliding direction of the movable support block 20. A winding wheel 24 is rotatably arranged between two adjacent movable support blocks 20 located at the same group of support structures. An circumscribed shaft 25 is coaxially fixed to the end of the winding wheel 24. The end of the circumscribed shaft 25 away from the winding wheel 24 passes through the movable support block 20 and extends to the outside of the movable support block 20. A connecting rope 34 is wound around the winding wheel 24. The end of the connecting rope 34 away from the winding wheel 24 extends to the inside of the protective tube 11.

[0025] like Figure 4-5As shown, a lifting groove 35 is provided on the inner wall of the casing 11 along the axial direction of the casing 11, and an inner groove 38 is provided on the side of the lifting groove 35 that is close to the ground 10 and inserted into the casing 11. An inclined surface is set between the inner groove 38 and the end wall of the lifting groove 35 on the side away from the opening. A lifting block 36 is provided in the lifting groove 35 for sliding along the axial direction of the casing 11. A movable abutment block 37 is inserted into the lifting block 36. The movable abutment block 37 slides radially along the casing 11 in the lifting block 36. An elastic cavity 40 is provided in the lifting block 36. A connecting block 41 is fixed to the part of the movable abutment block 37 located in the elastic cavity 40. The connecting block 41 extends into the elastic cavity 40 and slides in abutment with the inner wall of the elastic cavity 40. A tension spring 42 is provided in the elastic cavity 40 with the same elastic force direction as the sliding direction of the movable abutment block 37. The two ends of the tension spring 42 are respectively fixed to the connecting block 41 and the inner wall of the elastic cavity 40. When the movable abutting block 37 abuts against the inner wall of the lifting groove 35 , the tension spring 42 is stretched. When the movable abutting block 37 abuts against the inner wall of the retracting groove 38 , the tension spring 42 has no tension.

[0026] like Figure 2-3 As shown, a clamping rotating wheel 30 and a fixed block 33 are provided in the interval between two fixed support blocks 13 of the same support structure. The fixed block 33 is fixedly provided at the end of the fixed support block 13 away from the casing 11, and the clamping rotating wheel 30 is rotatably provided on the side of the fixed support block 13 closer to the casing 11. The extension path of the connecting rope 34 passes through the space between the clamping rotating wheel 30 and the fixed block 33. A rotating shaft 31 is coaxially fixedly provided at the rotating shaft end of the clamping rotating wheel 30. The rotating shaft 31 axially extends through the fixed support block 13 to the outside of the support structure, and a handle 32 is fixed to the end of the rotating shaft 31 away from the clamping rotating wheel 30. The outer curved surface of the clamping rotating wheel 30 facing the fixed block 33 is a convex structure. The convex end of the clamping rotating wheel 30 rotates with the clamping rotating wheel 30, narrowing the space between the clamping rotating wheel 30 and the fixed block 33. The outer curved surface of the convex end of the clamping rotating wheel 30 is fixed with an anti-slip layer. When the outer convex end is not provided, the clamping rotating wheel 30 can rotate itself when the connecting rope 34 moves, thereby reducing friction with the connecting rope 34 and increasing the service life of the connecting rope 34.

[0027] like Figure 6 As shown, a pressure spring 44 is provided on the side of the movable support block 20 located in the sliding groove 21, away from the casing 11. The direction of the elastic force of the pressure spring 44 is the same as the sliding direction of the movable support block 20. The two ends of the pressure spring 44 are respectively fixed to the movable support block 20 and the inner wall of the sliding groove 21. Under the elastic action of the pressure spring 44, the movable support block 20 can maintain its connection with the fixed support block 13, preventing the movable support block 20 from becoming disconnected from the fixed support block 13 during use, thereby improving the stability of the reinforced structure.

[0028] After the casing 11 is inserted into the ground 10, a certain length is left above the ground 10, and the auxiliary support plate 12 is inserted into the casing 11, and the fixed support block 13 is vertically aligned with the movable support block 20, and the end of the plug joint 22 is aligned with the opening of the plug groove 23, and then the movable support block 20 is pushed toward the casing 11. At this time, the plug joint 22 gradually slides into the plug groove 23 to plug the fixed support block 13 into the movable support block 20. When the casing 11 tends to sink, the casing 11 applies downward pressure on the movable support block 20 through the fixed support block 13. At this time, the movable support block 20 transfers the downward pressure to the auxiliary support plate 12. Since the contact area between the auxiliary support plate 12 and the ground 10 is large, it is not easy to sink and has a supporting effect on the casing 11. At this time, it can ensure that the casing 11 does not sink during the construction process, which is conducive to improving construction safety. By adopting the above technical solution, the end of the circumscribed shaft 25 away from the winding wheel 24 can be connected to the external driving element, and the external driving element controls the rotation and stopping of the winding wheel 24 through the circumscribed shaft 25, thereby controlling the length of the connecting rope 34 wound on the winding wheel 24. The end of the connecting rope 34 away from the winding wheel 24 can be tied to the end of the steel cage 43 of the bored pile away from the ground 10. At this time, the connecting rope 34 can keep the steel cage 43 stationary, and then the end of the other steel cage 43 can be welded and fixed to the end of the bundled steel cage 43 to complete the extension of the steel cage 43. The vertical position of the bundled steel cage 43 can be adjusted according to the actual working conditions through the driving element, which is conducive to the rapid welding operation of the steel cage 43.

[0029] When the steel cage 43 is lowered into the casing 11, the end of the steel cage 43 can abut against the movable abutment block 37. At this time, the gravity of the steel cage 43 is supported by the movable abutment block 37, and the connecting rope 34 resists the load on the lifting block 36 and the movable abutment block 37 through tension, thereby maintaining the stability of the steel cage 43. As the driving element is driven, the extension length of the connecting rope 34 inside the casing 11 can be controlled, thereby controlling the position of the lifting block 36 and the movable abutment block 37, and then controlling the position of the steel cage 43, so that the lower end of the steel cage 43 can be stabilized during the process of the steel cage 43 being hoisted, so that the steel cage 43 as a whole is in a stable motion state, avoiding poor stability of the steel cage 43 during hoisting. The movable abutment block 37 is pressed into the lifting block 36 by the abutment action of the end wall of the inner groove 38 away from the opening, and then moves into the lifting groove 35 and gradually returns to the starting position.

[0030] During the movement of the connecting rope 34, the rotating shaft 31 is rotated by holding the handle 32 and turning the handle 32, thereby controlling the rotation of the clamping rotating wheel 30. When the outer protruding end of the clamping rotating wheel 30 moves away from the fixed block 33, the connecting rope 34 can pass normally between the fixed block 33 and the clamping rotating wheel 30. When the outer protruding end of the clamping rotating wheel 30 moves toward the fixed block 33, the anti-slip layer of the outer protruding end of the fixed block 33 and the extrusion effect formed between the outer protruding end of the clamping rotating wheel 30 and the fixed block 33 work together to limit the movement of the connecting rope 34, thereby achieving the purpose of emergency braking of the connecting rope 34 when the movement speed of the connecting rope 34 is too fast.

[0031] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art will appreciate that the present invention is not limited to the above embodiments and that various modifications and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
