Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0035] see figure 1 As shown, the embodiment of the present invention provides a construction method for removing fillings on the arch of a double-curved arch bridge, comprising the following steps:

[0036] Step 1: Divide the area of ​​the bridge deck between two adjacent piers 1 into the first construction area 2, divide the longitudinal transport area 5 extending along the longitudinal direction of the bridge in the center of the bridge deck, and divide the longitudinal transport area 5 into the first construction area 2. The construction area 2 is equally divided into two second construction areas 3, and the second construction area 3 is divided into several third construction areas 4 extending along the longitudinal bridge direction along the horizontal bridge direction, see figure 2 and to image 3 As shown, the quantity of the third ...

Abstract

The invention discloses a construction method for dismantling padding on an arch of a two-way curved arch bridge. The construction method for dismantling the padding on the arch of the two-way curvedarch bridge comprises the following steps that areas, located between every two adjacent bridge piers, of the bridge surfaces are divided into first construction areas, longitudinal transportation areas extending in the longitudinal bridge direction are marked out at the centers of the bridge surfaces, each first construction area is divided into two second construction areas by the longitudinal transportation areas, and each second construction area is divided into a plurality of third construction areas in the horizontal bridge direction, wherein the third construction areas extend in the longitudinal bridge direction. The padding of the third construction areas is dismantling symmetrically and shipped out through the longitudinal transportation areas; and the padding of the longitudinaltransportation areas is dismantling symmetrically and shipped out. The construction method for dismantling the padding on the arch of the two-way curved arch bridge overcomes the defects of high safety risk and low work efficiency existing in traditional construction.

Description

technical field [0001] The invention relates to the field of reconstruction and construction of existing double-curved arch bridges, in particular to a construction method for removing fillers on the arches of double-curved arch bridges. Background technique [0002] The double-curved arch bridge is a light arch bridge type first created in 1964 by bridge builders in Wuxi County, Jiangsu Province. As of 1979, a total of 4,085 double-curved arch bridges had been built nationwide, with a total length of 350,000 meters, accounting for 25.7% of the total length of large and medium-sized highway bridges in the country during the same period. After entering the 1980s, double-curved arch bridges began to expose many problems, mainly (1) low load standard; (2) poor lateral connection; (3) sensitive to soft soil foundation settlement; (4) insufficient navigation clearance Wait. The most important problem is the insufficient bearing capacity of the arch ribs. [0003] In recent yea...
