Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building pile engineering technology, and specifically relates to a building pile reinforcement device. Background Technology
[0002] After drilling a hole at the construction site, a steel reinforcement cage is inserted, and then concrete is poured to form the pile body of the cast-in-place pile. Cast-in-place piles are widely used in bridge engineering. Part of the pile body is located below the river surface, thus providing stable support for the bridge on the water surface.
[0003] When the pile body is immersed in water for a long time, physical corrosion and chemical corrosion will occur. Physical corrosion is the phenomenon that certain components of concrete physically dissolve or expand, thereby causing structural damage and reduced strength. Common forms of physical corrosion include hydraulic erosion, freeze-thaw cycle damage, and wet-dry cycle damage. Chemical corrosion refers to the phenomenon that water molecules react with the chemical components in concrete, leading to a decrease in concrete performance and durability.
[0004] Under the influence of physical and chemical corrosion, the concrete surface of the pile body may develop problems such as detachment, honeycombing, cracks, and exposed reinforcement. These problems significantly reduce the service life of the pile body and, in severe cases, can even cause bridge collapse, posing a significant safety hazard.
[0005] Currently, the treatment methods for damaged concrete parts of underwater piles are as follows: remove debris from the concrete surface, roughen the damaged area, remove rust from exposed steel bars, clean the area to be repaired, and then repair it with epoxy mortar. However, after treatment, the pile body is still prone to the same problems recurring, which is not conducive to improving the service life of the pile body. Utility Model Content
[0006] The purpose of this invention is to provide a building pile reinforcement device that can provide stable and effective protection for the pile body, thereby extending the service life of the pile body.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a building pile reinforcement device, comprising a pile body, wherein a plurality of rubber rings are wrapped around the pile body at a position below the water surface, the plurality of rubber rings are evenly distributed in the vertical direction, the interior of the rubber rings is hollow, and a polytetrafluoroethylene plastic sleeve is fitted around the outside of the pile body and wrapped around the plurality of rubber rings, a connecting ring is provided on the lower periphery of the polytetrafluoroethylene plastic sleeve, and a plurality of fixed inserts embedded in the riverbed soil layer are provided on the lower side of the connecting ring.
[0008] A further feature of this invention is that the plurality of fixed pins are evenly spaced along the periphery of the connecting ring.
[0009] A further feature of this invention is that a clamping ring is fitted on the main body of the pile for pressing against the upper side of multiple rubber rings, and multiple threaded holes are opened on the periphery of the clamping ring, with locking bolts for abutting against the outer wall of the main body of the pile threaded holes.
[0010] A further feature of this invention is that the clamping ring includes a first clamping ring located on one side of the pile body and a second clamping ring located on the other side of the pile body. One end of the second clamping ring is hinged to the end of the first clamping ring. A connecting plate is provided at the end of the first and second clamping rings away from the hinged end. A through hole is provided on the connecting plate. A connecting bolt is provided between the first and second clamping rings, passing through the through hole of the two connecting plates and then threadedly connected by a nut.
[0011] A further feature of this invention is that the outer periphery of the main body of the pile is coated with epoxy asphalt paint.
[0012] A further feature of this invention is that the rubber ring is made of butyl rubber, which has excellent corrosion resistance at low temperatures and good oil and water resistance.
[0013] In summary, this utility model has the following beneficial effects:
[0014] 1. First, a polytetrafluoroethylene (PTFE) plastic sleeve is wrapped around the outside of the pile body. The PTFE plastic sleeve is embedded in the riverbed soil layer using multiple fixing pins on the lower side of the connecting ring. This completes the fixation of the PTFE plastic sleeve on the outside of the pile body. Then, the river water in the space between the PTFE plastic sleeve and the pile body is drained. Next, multiple rubber rings are wrapped around the pile body, evenly distributed vertically. Because the PTFE plastic sleeve has good corrosion resistance, it can effectively protect the pile body inside. At the same time, the rubber rings not only protect the pile body but also act as a buffer, reducing the impact of river water on the pile body. Ultimately, this helps to provide stable and effective protection for the pile body, thereby extending its service life.
[0015] Meanwhile, because the coefficient of friction of the polytetrafluoroethylene plastic sleeve is extremely low, it can further reduce the impact of river water on the main body of the pile, thus helping to protect the main body of the pile.
[0016] 2. By using multiple fixed posts evenly spaced along the circumference of the connecting ring, the multiple fixed posts can facilitate the stable fixation of the polytetrafluoroethylene plastic sleeve in the riverbed soil layer;
[0017] 3. When the inner side of the polytetrafluoroethylene plastic sleeve enters the river water and generates buoyancy on the rubber ring, the clamping ring is fitted onto the main body of the pile, and the rear end of the locking bolt is threaded into the threaded hole and pressed against the outer wall of the main body of the pile. At this time, the clamping ring can stably press on the upper side of multiple rubber rings, thereby positioning the position of multiple rubber rings.
[0018] 4. When it is necessary to put the clamping ring on the main body of the pile, one end of the second clamping ring is hinged to the end of the first clamping ring. At this time, the first and second clamping rings can be opened so that the first and second clamping rings wrap around both sides of the main body of the pile. Then, the first and second clamping rings are tightened so that the two connecting plates are in contact. Then, the connecting bolts are passed through the through holes on the two connecting plates and connected by the threaded nuts. At this time, the clamping ring can be conveniently put on the main body of the pile.
[0019] 5. The epoxy asphalt paint applied to the outer perimeter of the pile body provides stable and effective protection for the pile body due to its good corrosion resistance, thereby extending the service life of the pile body.
[0020] 6. The rubber ring is made of butyl rubber. Due to the corrosion resistance and water resistance of butyl rubber, it can further stabilize and effectively protect the pile body, thereby extending the service life of the pile body. Attached Figure Description

[0026] A building pile reinforcement device, referring to Figure 1 The pile reinforcement device includes a pile body 1, wherein multiple rubber rings 2 are wrapped around the pile body 1 at a position below the water surface. The rubber rings 2 are made of butyl rubber and are evenly distributed in the vertical direction. The interior of the rubber rings 2 is hollow. The outer wall of the pile body 1 is also coated with epoxy asphalt paint (not shown in the figure).
[0027] Reference Figure 1 , Figure 2 The main body 1 of the pile is also fitted with a polytetrafluoroethylene (PTFE) plastic sleeve 3, which wraps around multiple rubber rings 2. The PTFE plastic sleeve 3 is made of PTFE material. A connecting ring 31 is integrally provided on the lower circumference of the PTFE plastic sleeve 3. Multiple fixing posts 32 embedded in the riverbed soil are fixed to the lower side of the connecting ring 31 by bolts. The multiple fixing posts 32 are evenly spaced along the circumference of the connecting ring 31. At the same time, a clamping ring 4 is fitted on the main body 1 of the pile for pressing on the upper side of the multiple rubber rings 2. The clamping ring 4 has an L-shaped cross section, and multiple threaded holes 401 are opened on the circumference of the clamping ring 4. 401 is internally threaded with a locking bolt 402 for abutting against the outer wall of the pile body 1; and the compression ring 4 includes a first compression ring 41 located on one side of the pile body 1 and a second compression ring 42 located on the other side of the pile body 1. At the same time, one end of the second compression ring 42 is hinged to the end of the first compression ring 41, and a connecting plate 403 is bonded and fixed at the ends of the first compression ring 41 and the second compression ring 42 away from the hinge end. A through hole 4031 is provided on the connecting plate 403, and a connecting bolt 4032 is provided between the first compression ring 41 and the second compression ring 42, which passes through the through hole 4031 of the two connecting plates 403 and is connected by a nut thread.
[0028] Principle: First, a polytetrafluoroethylene (PTFE) plastic sleeve 3 is wrapped around the outside of the pile body 1. The PTFE plastic sleeve 3 is embedded in the riverbed soil layer using multiple fixing pins 32 on the lower side of the connecting ring 31. This completes the fixation of the PTFE plastic sleeve 3 to the outside of the pile body 1. Then, the river water in the space between the PTFE plastic sleeve 3 and the pile body 1 is drained. Next, multiple rubber rings 2 are wrapped around the pile body 1, and the multiple rubber rings 2 are evenly distributed in the vertical direction. Finally, a clamping ring 4 is fitted onto the pile body 1, and the locking bolts 402 are used for threaded fastening. The rear end of the ring 4, connected to the threaded hole 401, abuts against the outer wall of the pile body 1. At this time, the clamping ring 4 can stably press against the upper side of multiple rubber rings 2, thereby positioning the multiple rubber rings 2. Since the polytetrafluoroethylene plastic sleeve 3 has good corrosion resistance, it can effectively protect the pile body 1 inside. At the same time, the rubber rings 2 can also act as a buffer while protecting the pile body 1, reducing the impact of river water on the pile body 1. Ultimately, this can help to provide stable and effective protection for the pile body, thereby extending the service life of the pile body.
[0029] Meanwhile, since the coefficient of friction of the polytetrafluoroethylene plastic sleeve 3 is extremely low, it can further reduce the impact of river water on the main body of the pile 1, thus helping to protect the main body of the pile 1.
