An integral bridge pier reinforcement structure and its construction method

Abstract

The invention discloses an integral type bridge pier reinforcing structure and a construction method thereof. The integral type bridge pier reinforcing structure comprises a first cushion layer and asecond cushion layer which are built on the top surface of a riverbed supporting course in sequence; splitter piers are connected to the part, close to the bridge pier, of the top surface of the second cushion layer; the splitter piers are of annular structures and surround the bridge pier; gaps between the splitter piers and the bridge pier are filled with packing layers used for reinforcing connection; row piles are arranged on one sides, close to the river bank, of the first cushion layer and the second cushion layer; each row pile comprises a plurality of drilling cast-in-place piles arranged on the river bank; the bottoms of the drilling cast-in-place piles extend into the riverbed supporting course; retaining walls are arranged on one side surfaces, far away from the river bank, of the row piles; crown beams are also fixedly connected to the top surfaces of the row piles; reinforcements are embedded in the tops of the drilling cast-in-place piles; the drilling cast-in-place pileson the river bank on one side are connected to the bottom surfaces of the crown beams through the reinforcements. According to the integral type bridge pier reinforcing structure, a problem caused byexisting supplementing foundation pile reinforcement is effectively solved, and therefore, the integral performance and the erosion prevention performance of the bridge pier and a foundation are improved.

Description

technical field [0001] The invention relates to the technical field of bridge and bridge pier reinforcement, in particular to an integral bridge pier reinforcement structure and a construction method thereof. Background technique [0002] Bridge reinforcement refers to the improvement of the bearing capacity and service performance of components and even the entire structure through certain measures to meet new requirements. The reasons for strengthening are various, such as the age of the bridge, poor design, poor construction quality or severe overloading of vehicles. After the bridge is reinforced, the service life of the bridge can be extended, and with a small amount of capital investment, the bridge can meet the demand of traffic volume, and it can also ease the concentration of bridge investment, prevent and avoid the loss of people and property caused by bridge collapse. [0003] However, bridge reinforcement has become a major problem after bridge construction. At...
