[0002] A bridge is a structure built over water or in the air for traffic. It is generally composed of a bridge body and bridge piles. The bridge piles are used to support the bridge body. Most modern bridges are viaducts built in the air to relieve urban congestion. Their bridge piles are usually buried underground, such as Figure 1 As shown, a bridge pile includes a base 90 and a pile body 91, wherein the base 90 is arranged at the bottom of the pile body 91, and the bridge is arranged at the upper end of the pile body, and a part of the base 90 and the pile body 91 are buried underground.
[0003] With the development of science and technology and economy, the number of motor vehicles in cities has gradually increased, and traffic congestion is prone to occur. Therefore, some viaducts with traffic congestion need to widen the bridge deck, which leads to the need to reinforce and widen the bridge piles. At the same time, some early-built viaducts also need to reinforce and maintain the bridge piles. The existing reinforcement method is usually to directly weave steel bars and pour cement on the outside of the bridge frame.

DETAILED DESCRIPTION
[0021] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp. Embodiment 1:
[0022] A bridge pile foundation reinforcement device, including a reinforcement cage 1 arranged outside a pile body 91, the reinforcement cage 1 includes a cage 1 2 and a cage 2 3, both cage 1 2 and cage 2 3 are provided with vertical support rods 4 and horizontal support rods 5, cage 1 2 is arranged at the lowest side and fits with a base 90, a vertical hole 6 is provided in a circular shape on the base 90, the vertical support rod 4 in cage 1 2 is relatively long, one end of which is installed in the vertical hole 6 and inserted into the rock layer at the bottom of the base 90, and the other end is flush with the upper end surface of cage 1 2, and two guide sleeves are provided on the vertical support rod 4 7, a guide hole 8 is provided in the middle of the guide sleeve 7, and the transverse support rod 5 is arranged in the guide hole 8. Before installing the transverse support rod 5, a plug hole 9 needs to be provided on the pile body 91, and the transverse support rod 5 is knocked into the plug hole 9. When the transverse support rod 5 is inserted into the plug hole 9, the vertical support rod 4 can be fixed to the pile body 91. The cage 1 2 and the cage 2 3 are both provided with a through hole 10. After the cage 1 2 and the cage 2 3 are manufactured, the transverse support rod 5 is arranged in the through hole 10, so that the cage 1 2 and the cage 2 3 are positioned by the transverse support rod 5 When the reinforced cage 1 is used as a temporary support, the guide hole 8 can be used as a threaded hole, and a thread can be opened on the transverse support rod 5, so that the transverse support rod 5 can be rotated and inserted into the insertion hole 9 and tightened. At this time, the transverse support rod 5 is fixed to the vertical support rod 4, and the tail of the transverse support rod 5 can be directly fixed to the cage 1 and the cage 2 3. When the transverse support rod 5 and the vertical support rod 4 are used as temporary reinforcement, the reinforced cage 1 is set to protect the internal vertical support rod 4 and the transverse support rod 5, reduce external corrosion thereto, and at the same time, prevent the exposed part of the support rod from being sharp while ensuring the aesthetics, thereby protecting the support rod and protecting pedestrians.
[0023] When it is necessary to pour cement, there is no need to open threads on the transverse support rod 5 and the guide hole 8. When the cement solidifies, the cage 1 2 and the cage 2 3 need to be removed. Therefore, after the installation of the cage 1 2 and the cage 2 3 is completed, the transverse support rod 5 needs to be knocked inward along the axis. When the transverse support rod 5 is separated from the through hole 10, the through hole 10 needs to be sealed by the sealing screw 29 to ensure that the cement does not leak out and the steel bar does not expose the cement surface after the pouring is completed. At the same time, before pouring cement, the inner surface of the cage 1 2 and the cage 2 3 is sprayed with a release agent. The recycled cage 1 2 and the cage 2 3 can be assembled with new transverse support rods 5 and vertical support rods 4 and can be reused. Regardless of whether the reinforced cage 1 is used as a temporary support or as a reinforced cement mold, it can save on-site construction time and reduce construction costs by producing it in advance and sending it out in matching sets.
[0024] There are four cages 2, which are wrapped around the bottom layer outside the pile body 91. A bottom mounting frame 27 is fixed on the base 90 by screws. A positioning groove 28 is provided on the bottom mounting frame 27. The bottom of the cage 2 is inserted into the positioning groove 28. The cage 2 3 is arranged at the upper end of the cage 2. Four cages 2 3 form a layer. The number of layers of the cage 2 3 is related to the height of the pile body 91. The horizontal support rod 5 of the cage 2 3 has the same structure as the horizontal support rod 5 of the cage 2. The vertical support rod 4 of the cage 2 3 is the same as the vertical support rod 4 of the cage 2. The vertical support rod 4 is different. Both ends of the vertical support rod 4 in the cage 2 3 are exposed by 30MM of the cage 2. The tops of the vertical support rods 4 in the cage 1 2 and the cage 2 3 are provided with positioning holes 11. The bottoms of the vertical support rods 4 in the cage 1 2 are inserted into the vertical holes 6. The bottoms of the vertical support rods 4 in the cage 2 3 are provided with positioning columns 12. When the positioning columns 12 are plugged into the positioning holes 11, because the length of the vertical support rod 4 is greater than that of the cage 2 3, horizontal welding avoidance grooves 13 are formed at the upper and lower ends of the cage 2 3.
[0025] Both cage 1 2 and cage 2 3 are provided with enclosure rods 14, which are welded to the upper and lower ends of the vertical support rod 4. When cage 2 3 is being installed, the junction of the two cages 2 3 is at the position of welding avoidance groove 1 13, and the enclosure rods 14 in the two cages can be welded together by a welding gun, thereby increasing the connection strength of the upper and lower cages 2 3.
[0026] An annular sealing plate 15 is provided on the welding avoidance groove 13, and two annular sealing plates 15 are provided on each layer. The annular sealing plate 15 seals the welding avoidance groove 13. Both the cage 1 2 and the cage 2 3 are provided with a mounting hole 18. The annular sealing plate 15 is fixed through the mounting hole 18 and screws. The cage 1 2, the cage 2 3 and the annular sealing plate 15 form a mold cavity 16, so that there will be no leakage problem after pouring cement.
[0027] A vertical welding avoidance groove 2 17 is also provided between the enclosure 1 2 and the enclosure 2 3, and the enclosure rod 14 of each layer can be connected through the welding avoidance groove. A vertical sealing plate 19 is provided on the welding avoidance groove 27. Both the enclosure 1 2 and the enclosure 2 3 are provided with mounting holes 20, and the vertical sealing plate 19 is fixed with screws through the mounting holes 20. The four enclosures 1 2 or the enclosure 2 3 of each layer are connected through the vertical sealing plate 19, thereby increasing the connection strength of the enclosure 1 2 and the enclosure 2 3 of each layer, and at the same time, it is convenient to plug and weld the enclosure rods 14 in the four enclosures 1 2 and the enclosure 2 3, so that the enclosure rods 14 are integrated, and the structural strength between each enclosure is increased. The structural strength between the enclosure 1 2 and the enclosure 2 3 can be ensured by the vertical sealing plate 19 and the annular sealing plate 15 to prevent collapse.
[0028] The installation process of the above-mentioned bridge pile foundation reinforcement device is as follows: A hole 6 is opened on the base 90, and a socket 9 is opened on the pile body 91. When opening the hole 6 and the socket 9, it is necessary to avoid the steel bars originally in the base 90 and the pile body 91, and then the surface of the pile body 91 is roughened. Then the reinforcing cage 1 is installed. First, the cage 1 2 is transported to the installation position by a crane, and the vertical support rod 4 in the cage 1 2 is inserted into the vertical hole 6. The vertical support rod 4 is inserted into the rock layer by a pile driver, and the transverse support rod 5 is pushed into the socket 9. After all the cages 1 2 are installed in turn, the enclosure rod 14 in the cage 1 2 is welded by a welding machine, and then the vertical sealing plate 19 at the cage 1 2 is installed, and then the cage 2 3 is installed by a crane. After the transverse support rod 5 in the cage 2 3 is inserted, the enclosure rod 14 in the welding avoidance groove 1 13 is welded by a welding machine, so that the cage 2 3 is fixed to the cage 1 2, and the installation of the cage 2 3 is completed in turn. Embodiment 2:
[0029] The difference between the second embodiment and the first embodiment is that: a flow channel air hole 21 is opened inside the enclosure rod, and a joint 22 is provided at one end of the enclosure rod. The joint 22 in one enclosure 2 3 is plugged into the enclosure rod 14 in its adjacent enclosure, and a sealing rubber 23 is provided in the joint 22, so that the flow channel air hole 21 is in a sealed state. A pair of insert pipes 24 are also provided on the vertical sealing plate 19 arranged at the rear end of the enclosure, and the two insert pipes 24 are respectively provided with an air inlet hole 25 and an air outlet hole 26. The two insert pipes 24 are respectively inserted into the two ends of the flow channel air hole 21. When cement is input into the mold cavity 16, hot air is input into the flow channel air hole 21, thereby accelerating the solidification of the cement and shortening the construction period.
[0030] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
