Anchor rod pile reinforcing bearing platform structure used for reinforcing deformed bridge pile and construction method thereof

Abstract

The invention provides an anchor rod pile bridge pile reinforcing structure. The anchor rod pile reinforcing bearing platform structure used for reinforcing a deformed bridge pile comprises a reinforcing bearing platform fixed on the periphery of the bottom of the bridge pile and a plurality of anchor rod static-pressure reinforcing piles, wherein press pile holes are formed in the reinforcing bearing platform, the number of the press pile holes is the same with the number of the anchor rod static-pressure reinforcing piles, the bottom pile end of each anchor rod static-pressure reinforcing pile is embedded into the soil layer under the reinforcing bearing platform by a designed depth through the corresponding press pile hole, the top pile head of each anchor rod static-pressure reinforcing pile is embedded into the reinforcing bearing platform, the top surface of the pile head of each anchor rod static-pressure reinforcing pile is lower than the upper surface of the reinforcing bearing platform, a pile sealing structure is arranged on the top of each pile head, and a plurality of reinforcing rebars are arranged in a fixing bearing platform in a horizontally and longitudinally cross mode. According to the anchor rod pile reinforcing bearing platform structure used for reinforcing the deformed bridge pile, the structure is simple, a bridge can be reinforced and maintained on the premise that an original bridge pile and an original deck are not changed, the deformed bridge can be rehabilitated, the bearing capacity of the bridge is guaranteed, construction is convenient and can be conducted on the premise that a passageway on the deck is not blocked, and normal traffic on the bridge is not influenced during maintenance.

Description

technical field [0001] The invention relates to a bridge pile reinforcement structure, in particular to an anchor pile reinforcement cap structure for reinforcing deformed bridge piles. Background technique [0002] With the continuous development of traffic, in order to reduce traffic congestion, many overpasses and viaducts have appeared on urban roads. Due to the rapid increase in traffic volume, more and more large-tonnage vehicles, coupled with some traffic accidents and natural factors, the bridge piles of some viaducts and overpasses have been damaged and deformed, resulting in uneven bridge decks, thereby reducing the overall bridge structure. The ductility and bearing capacity have seriously affected the durability of the structure, and there are hidden dangers of engineering accidents. For the above situation, it is necessary to repair the bridge piles and adjust the bridge deck. The existing bridge pile maintenance generally involves digging out the pile caps of ...

Problems solved by technology

Due to the rapid increase in traffic volume, more and more large-tonnage vehicles, coupled with some traffic accidents and natural factors, the bridge piles of some viaducts and overpasses have been damaged and deformed, resulting in uneven bridge decks, thereby reducing the overall bridge structure. The ductility and bearing capacity have seriously affected the durability of the structure, and there are hidden dangers of engineering accidents

For the above situation, it is necessary to repair the bridge piles and adjust the bridge deck. The existing bridge pile maintenance generally involves digging out the pile caps of the original bridge piles, and repairing and repairing the broken or damaged bridge piles. Or new piles are built around the excavated pile foundation. During the maintenance process, the pile foundation cap of the bridge pile is excavated, its bearing capacity is reduced, and there are potential safety hazards. The bridge body must be closed and repaired. The procedures are cumbersome and require a lot of manpower and material resources. The construction time is relatively long, and the long-term road closure will affect the normal traffic.
