Description
Technical Field
[0001] The utility model relates to the field of reinforcement, in particular to an underwater pile foundation reinforcement device. Background Art
[0002] The pile foundation is used to support the bridge, with one part placed inside the water body and the other part exposed outside the water body. With the scouring of water flow and other reasons, the pile foundation will gradually become damaged and exposed, and the exposed steel bars will also be corroded, and even further cause the main bars to corrode, which will have a great impact on the durability and safety of the bridge structure. In order to prevent the pile foundation from further rusting, the pile foundation is reinforced. The existing method is to wrap the pile with a sleeve to play a role in reinforcement and rust prevention.
[0003] During the construction and reinforcement process, the sleeve is first put on the outside of the pile body, and after the position of the sleeve is fixed, grouting is then poured into the gap between the sleeve and the pile body to make the two bond together. However, the sleeve is relatively large, and the gaps between the reinforcement sleeve and the pile body may be of different sizes during construction operations. In addition, it is difficult for construction workers to measure the size of each gap, and it is impossible to ensure that the gaps are the same or close in size, resulting in uneven grouting and uneven force when the pile foundation is subjected to external forces, affecting the reinforcement effect. Therefore, how to make the gaps between the reinforcement sleeve and the pile body the same size is an urgent problem to be solved.
[0004] In addition, if the height of the sleeve is greater than 5 meters, it is difficult to operate the construction. As mentioned above, a sleeve generally does not exceed 5 meters. Therefore, some pile foundations need to be equipped with 2 or more sleeves to meet the needs of reinforcement. At present, the two sleeves are connected by bite overlap bonding, but this connection method is not convenient for grouting, easy to leak grout, and even cannot ensure that each sleeve is grouted evenly, affecting the quality of reinforcement.
