Description

Technical Field

[0002] With the development of economic construction, bridge pile foundations, as the most important foundation type in bridge engineering, are widely used. Bridge pile foundations are the lowest part of the bridge structure directly in contact with the foundation and an important part of the lower structure of the bridge. After being subjected to various loads, stress and deformation will be generated. Therefore, in order to ensure the normal use and safety of the bridge, bridge pile foundations must have sufficient strength and stability, and the deformation should also be within the allowable range. After long-term use of highway bridges, the pile foundations will decline or tilt under the action of various loads, and the columns or pile foundations may also crack or break, so regular inspection and reinforcement are required.

[0003] In order to improve the strength of bridge pile foundations, many improvements have been made to the reinforcement structures of bridge devices in the prior art.

A first annular frame 5 is provided on the new bearing platform 4, and the first annular frame 5 is arranged with the bearing column 2 as the axis. A second annular frame 6 is provided on the side of the bearing column 2. A number of first sliding seats 7 are slidably connected in the first annular frame 5, and a number of second sliding seats 8 are slidably connected in the second annular frame 6. Installation ears 9 are fixedly installed on the sides of the number of first sliding seats 7 and second sliding seats 8. A support steel member 10 is provided between the installation ear 9 on the first sliding seat 7 and the installation ear 9 on the second sliding seat 8. The first sliding seat 7 and the second sliding seat 8 can both be fixed in position.

[0030] The specific implementation manner in this embodiment: The above-mentioned first annular frame 5, second annular frame 6, first sliding seat 7, second sliding seat 8, installation ear 9 and support steel member 10 are all made of high-strength steel products. When it is necessary to reinforce the pile foundation of the bridge body 3, a new bearing platform 4 is cast on the side of the original bearing platform 1. After the concrete of the new bearing platform 4 has passed the maintenance period, the first annular frame 5 is fixedly installed on the new bearing platform 4, and the support steel member 10 is installed between the first sliding seat 7 and the second sliding seat 8 through the cooperation of the installation parts and the installation ear 9 for reinforcing and supporting the bearing column 2. By the above method, the pile foundation of the bridge body 3 is reinforced, saving a large amount of time and labor, and thus reducing the cost of reinforcing the pile foundation of the bridge body 3.

[0031] It should be noted that since the bearing column 2 will generate a lateral force in the situation, causing the bearing column 2 to tilt towards one side, the above-mentioned first sliding seat 7 and second sliding seat 8 can move within the first annular frame 5 and the second annular frame 6 respectively. By moving the first sliding seat 7 and the second sliding seat 8, the position of the support steel member 10 can be adjusted according to the actual tilting situation of the bearing column 2.
