Embodiment 1

[0022] like figure 1 and figure 2 As shown, a bridge pier deviation correction and reinforcement system includes a bored pile 3 at a certain distance from the bridge pier 2 and a first steel plate 9 arranged on the top tie beam of the bridge pier. In this embodiment, the drill There are two rows of cast-in-place piles 3, arranged in the direction perpendicular to the crossed road 1, 3.5m outside the existing pier 2, with a pile diameter of 1.2m, a pile spacing of 3m, and a pile length of 30m. Wherein, the top of the pile foundation of the bored pile 3 is provided with a cap 4, and the cap 4 is away from the preset reinforcement on the side of the pier 2, and the preset reinforcement corresponds to the first steel plate 9; the cap 4 A concrete prefabricated block 5 is arranged near the side of the bridge pier 2, a second steel plate 10 is arranged on the other side of the concrete prefabricated block 5, and a hydraulic jack 6 is installed between the second steel plate 10 and...

Abstract

The invention relates to a system for deviation rectifying and reinforcing of a pier. The system comprises a bored pile and a first steel plate, wherein a certain gap is formed between the bored pile and the pier; the first steel plate is arranged on the pile top collar beam of the pier; a bearing table is arranged at the top of the pile base of the bored pile; steel bars are prearranged on the bearing table on the side far away from the pier, and correspond to the first steel plate; a concrete pre-cast block is arranged on the bearing table on the side near the pier; a second steel plate is arranged on the other side of the concrete pre-cast block; a hydraulic jack is mounted between the first and the second steel plates; and the resultant center of the hydraulic jack is superposed with the axial line of the bored pile. Through the adoption of the system provided by the invention, the deviation of the pier is solved effectively, the permanent reinforcing is realized, the construction safety and the engineering quality are ensured, the application steps are definite and feasible, and the operability is very high.

Description

technical field [0001] The invention relates to a bridge maintenance and construction system, in particular to a bridge pier deviation correction and reinforcement system. Background technique [0002] At present, in the construction of roads and bridges, the foundations of highways and railway bridges mostly use pile foundations. When the bridge pile foundation is set on the side of the road to be crossed, and the road to be crossed is a soft soil foundation, during the construction of the road and bridge, due to reasons such as unreasonable construction sequence and improper handling of the soft soil foundation, the phenomenon of bridge pier deflection often occurs. For bridges that have been put into use, due to changes in boundary conditions, overloading, etc., there are also many piers that are out of position. Bridges are different from other buildings in that their pier structures are large in size, high in cost, poor in construction conditions, and difficult. When t...
