Description

Technical Field

[0001] The invention relates to the technical field of square piles, in particular to an oblique-mouth pile-wrapping hoop for repairing square piles. Background Art

[0002] Square piles are common precast concrete or steel piles with a square cross-section. They are widely used in foundation construction for buildings, bridges, docks, and other projects, primarily to support vertical and horizontal loads. They are typically made of concrete, reinforced concrete, or steel and are installed into the foundation by driving, pressing, or drilling to improve the foundation's bearing capacity and stability.

[0003] In the early days, a large number of concrete square piles were used as the pile foundation of the wharf. As time went by, the carbonization of the concrete deepened, and various concrete cracks or steel bar corrosion gradually appeared in these square piles, seriously affecting the durability and bearing capacity of the pile foundation. Pile foundation defects are usually prone to occur in the area from 5m below the mud to the pile top. Therefore, pile wrapping is used to reinforce and repair the defective positions. The existing pile wrapping clamp device for repairing square piles lacks a structure that is convenient for preventing water leakage during concrete pouring, which leads to an increase in the moisture content in the concrete, affecting the coagulation and hardening process of the concrete, thereby reducing the strength of the concrete. Based on the shortcomings of the existing technology, the present invention designs an oblique pile wrapping clamp for square pile repair. Summary of the Invention

[0006] As a preferred technical solution of the present invention, a drainage structure is fixedly installed on the outer surfaces of the two clamps, and the two drainage structures include a second sealing tube and a second inner tube.

[0007] As a preferred technical solution of the present invention, the two second inner tubes are arranged on the inner wall of the clamp, and first drainage holes are opened on both sides of the outer surface of the two second inner tubes.

[0008] As a preferred technical solution of the present invention, first protruding blocks are fixedly mounted on both sides of the outer surfaces of the two second sealing tubes, and second springs are fixedly mounted on the outer surfaces of the two first protruding blocks.

[0009] As a preferred technical solution of the present invention, a second protruding block is fixedly installed on one end of the two second springs, and a third inner tube is fixedly installed between the two second protruding blocks.

[0010] As a preferred technical solution of the present invention, the two third inner tubes are slidably connected to the second sealing tube, and second drain pipes are provided on both sides of the outer surfaces of the two third inner tubes.

[0011] As a preferred technical solution of the present invention, two fixing seats are fixedly installed on the top of the two clamps, connecting blocks are fixedly installed inside the two fixing seats, two fixing holes are opened inside the two connecting blocks, and a fixing structure is arranged above the four connecting blocks.

[0012] As a preferred technical solution of the present invention, the fixing structure includes two fixing rods and four threaded blocks, the internal threads of the two fixing rods are installed with threaded rods, one end of the two threaded rods is fixedly installed with a first turning handle, the other end of the two first turning handles is fixedly installed with a top plate, and two fastening bolts are provided inside the four threaded blocks.

[0013] As a preferred technical solution of the present invention, two groups of hooks are fixed between the two fixing rods by bolts, and a bidirectional screw rod is rotatably installed between one group of hooks, and a second handle is fixedly installed inside the bidirectional screw rod.

[0014] As a preferred technical solution of the present invention, a limiting rod is fixedly installed between another group of hooks, the bidirectional screw rod is threadedly connected to two threaded blocks, and the limiting rod is movably connected to the other two threaded blocks.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The oblique-mouth pile clamp for square pile repair has an anti-seepage structure. When the two clamps are fixed to the two sides of the square pile by steel bars and concrete needs to be poured in the gap between the clamp and the square pile, the hinged cover is opened, and then one end of the conduit for conveying concrete is inserted into the first inner tube and pressed downward. At this time, the sliding cover drives the side blocks on both sides to slide inside the side groove, thereby separating the sliding cover from the first inner tube. At this time, the interior of the clamp is connected to the conduit, and pouring can begin. After pouring is completed, the conduit is pulled out. At this time, the two first springs are released and reset, bringing the sliding cover back into the first inner tube. At this time, the hinged cover is quickly closed to prevent water seepage, thereby achieving the purpose of preventing water seepage when pouring concrete and improving the repair strength of the device.

[0017] 2. This oblique-mouth pile clamp for square pile repair has a drainage structure. When the two clamps are fixed to the surface of the square pile by steel bars, water exists inside the two clamps. At this time, by inserting the water pump conduit into the third inner tube and pressing it inward, the second spring is compressed, driving the third inner tube to slide inside the second sealed tube. When the second drainage pipe coincides with the first drainage hole, the water inside the clamp enters the water pump conduit through the first drainage hole. At this time, the water inside the clamp can be pumped out by starting the water pump. After the water is pumped out, the third inner tube is reset by releasing the force of the spring. By pouring concrete into the clamp and waiting for it to solidify, water leakage can be prevented from occurring in the gap between the third inner tube and the second sealed tube.

[0018] 3. This oblique-mouth pile clamp for square pile repair has a fixing structure. When the two clamps are butt-jointed and installed, the two fixing rods are fixed above the repair site by bolts. Then, the slots of the fastening bolts are aligned with the fixing holes and connected by bolts. The butt-jointing work can be carried out. By turning the second handle, the bidirectional screw rod can be rotated. Due to the limitation of the limiting rod on the other side, the four threaded blocks can be moved in opposite directions at the same time, so that the two clamps can be moved toward the inside of the square pile at the same time. A sealing strip is provided at the connection of the two clamps. When the two clamps are in contact, they are fixed to the outer surface of the square pile by steel bars. Then the fixing structure is removed to complete the pile fixing. The symmetrical arrangement on the left and right sides can ensure the pile fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] See also Figure 6-7 A drainage structure 3 is fixedly mounted on the outer surface of the two clamps 1, and the two drainage structures 3 include a second sealing tube 31 and a second inner tube 32. The two second inner tubes 32 are arranged on the inner wall of the clamp 1, and first drainage holes 33 are opened on both sides of the outer surface of the two second inner tubes 32. First protrusions 34 are fixedly mounted on both sides of the outer surface of the two second sealing tubes 31, and second springs 35 are fixedly mounted on the outer surfaces of the two first protrusions 34. A second protrusion 36 is fixedly mounted on one end of the two second springs 35, and a third inner tube 37 is fixedly mounted between the two second protrusions 36. The two third inner tubes 37 are slidably connected to the second sealing tube 31, and second drainage pipes 38 are opened on both sides of the outer surface of the two third inner tubes 37.

[0031] By inserting the water pump conduit into the third inner tube 37 and pressing it inward, the second spring 35 is compressed, driving the third inner tube 37 to slide inside the second sealing tube 31. When the second drain pipe 38 coincides with the first drain hole 33, the water inside the clamp 1 enters the water pump conduit through the first drain hole 33. At this time, the water inside the clamp 1 can be pumped out by starting the water pump. After the pumping is completed, the third inner tube 37 is reset by releasing the force of the spring. By pouring concrete into the inside of the clamp 1 and waiting for it to solidify, water leakage can be avoided in the gap between the third inner tube 37 and the second sealing tube 31.

[0032] See also Figure 3 and Figure 8 Two fixing seats 5 are fixedly installed on the top of the two clamps 1, and connecting blocks 6 are fixedly installed inside the two fixing seats 5. Two fixing holes 7 are provided inside the two connecting blocks 6, and a fixing structure 4 is provided above the four connecting blocks 6. The fixing structure 4 includes two fixing rods 41 and four threaded blocks 48. The threaded rods 42 are threadedly installed inside the two fixing rods 41, and the first turning handles 43 are fixedly installed on one end of the two threaded rods 42.

[0033] Fix the two fixing rods 41 above the repair area with bolts, then align the slots of the fastening bolts 49 with the fixing holes 7 and connect them with bolts to carry out the docking work. By turning the second handle 47, the bidirectional screw rod 46 can be rotated. Due to the limitation of the limiting rod 410 on the other side, the four threaded blocks 48 can move in the opposite direction at the same time, so that the two hoops 1 can move toward the inside of the square pile at the same time. A sealing strip is provided at the connection between the two hoops 1. When the two hoops 1 are in contact, they are fixed to the outer surface of the square pile by steel bars, and then the fixing structure 4 is removed to complete the pile wrapping and fixation.

[0034] Working principle: when an oblique-mouth pile clamp for square pile repair is used, first fix the two fixing rods 41 above the repair site with bolts, then align the slots of the fastening bolts 49 with the fixing holes 7, and connect them with bolts to carry out docking work. By turning the second turning handle 47, the bidirectional screw rod 46 can be rotated. Due to the limitation of the limiting rod 410 on the other side, the four threaded blocks 48 can move in opposite directions at the same time, so that the two clamps 1 can move toward the inside of the square pile at the same time. A sealing strip is provided at the connection between the two clamps 1. When the two clamps 1 are in contact, they are fixed to the outer surface of the square pile by steel bars. Then the fixing structure 4 is removed to complete the pile fixing. Then, the water pump conduit is inserted into the third inner tube 37 and pressed inward. At this time, the second spring 35 is compressed, driving the third inner tube 37 to slide inside the second sealing tube 31. When the second When the drainage pipe 38 coincides with the first drainage hole 33, the water inside the clamp 1 enters the water pump conduit through the first drainage hole 33. At this time, the water inside the clamp 1 can be pumped out by starting the water pump. After the water is pumped out, the third inner tube 37 is reset by the spring release, and finally the hinged cover 22 is opened. Then, one end of the conduit for conveying concrete is inserted into the first inner tube 23 and pressed downward. At this time, the sliding cover 25 drives the side blocks 26 on both sides to slide inside the side groove 24, thereby allowing the sliding cover 25 to detach from the first inner tube 23. At this time, the interior of the clamp 1 is connected with the conduit, and pouring can be started. After the pouring is completed, by pulling out the conduit, the two first springs 210 are released and reset, bringing the sliding cover 25 back to the first inner tube 23. At this time, the hinged cover 22 is quickly closed to prevent water seepage. After the concrete solidifies, the outer surface of the clamp 1 is covered with geotextile to stop water.
