Building bridge pile foundation strengthening device

Abstract

The invention discloses a building bridge pile foundation strengthening device. A pile foundation is included. A transverse supporting column is arranged on the upper surface of the pile foundation. Fixing bases are connected to the two sides of the surface of the middle portion of the pile foundation. Fixing holes are drilled in the two sides in the fixing bases on the two sides. Connecting columns are connected to the surfaces of the middle portions of the fixing bases on the two sides. Steel bars are wound around the surfaces of the connecting columns. A triangular support is arranged at the bottom of the pile foundation. Buffering blocks are arranged on the surfaces of the four corners of the pile foundation. Fixing devices are arranged above and below the connecting columns on the twosides through screws. Protection plates are arranged between the upper portions of the connecting columns on the two sides and the fixing devices and between the lower portions of the connecting columns on the two sides and the fixing devices. Strengthening columns are arranged at the middle portions in the fixing devices, buffering columns are arranged on the surfaces of the top ends in the strengthening columns through screws, the fixing bases can be effectively fixed and installed by installing the fixing bases and the fixing holes to the two sides of the pile foundation, and through the arranged connecting columns, the middle portion of the pile foundation can be protected through the fixing bases.

Description

technical field [0001] The invention relates to a reinforcement device, in particular to a construction bridge pile foundation reinforcement device, which belongs to the technical field of construction. Background technique [0002] The bridge foundation is the lowest part of the bridge structure directly in contact with the foundation, and is an important part of the bridge substructure. The part of the formation that bears the load from the foundation is called the foundation. After the foundation and foundation are subjected to various loads, they will produce stress and deformation. In order to ensure the normal use and safety of the bridge, the foundation and foundation must have sufficient strength and stability, and the deformation should also be within the allowable range. The bridge foundation The function is to bear all the loads from the superstructure and transfer them and the load of the substructure to the foundation. Therefore, for the safety and normal use ...

AI Technical Summary

Problems solved by technology

Therefore, for the safety and normal use of the whole bridge, the foundation and foundation are required to have sufficient strength, stiffness and overall stability so that it does not produce excessive horizontal displacement or uneven settlement. During construction, the bridge pile foundation needs to be reinforced. After a long time of use, the existing reinforcement device is difficult to play its due role. At least the bridge pile foundation is damaged, which increases property loss and has certain safety hazards.
