Embodiment Construction

[0021] Such as figure 1 , 2 Shown, a kind of new-style road bridge buttress structure, it comprises pylon 1, buttress 2, connecting cable 3, waterproof and drainage facility 4; Said pylon is arranged on both sides of abutment 5, and is connected with abutment consolidation, One end of the steel cable is connected to the tower column through anchorage, and one end is connected to the preset threaded steel pipe holes 6 on both sides of the strapping plate through bolts 7 through the rope hole. , the two sides of the other end of the board are connected with the steel cable 3 by bolts through the reserved hole 6, and the upper end of the steel cable is connected with the tower column by anchoring. The waterproof and drainage facilities 4 are arranged below the board.

[0022] Further, the two sides of the said board are provided with side-standing channel-shaped steel 9, and the longitudinal sides and upper and lower sides of the channel-shaped steel are provided with openings,...

Abstract

The invention belongs to the technical field of bridge construction and assembling and specifically relates to a novel road and bridge approach slab and a construction method thereof. The invention discloses a bridge abutment approach slab to fundamentally solve a problem of bumping at bridge-head. The novel road and bridge approach slab comprises tower columns, an approach slab, a connecting cable and a waterproof and drainage facility; the tower columns are arranged on the two sides of a bridge abutment and fixedly connected with the bridge abutment; one end of the connecting cable is connected with the tower columns through anchors; the other end of the connecting cable is connected with bolts on the two sides of the approach slab; one end of the approach slab is erected on the bridge abutment and connected with a beam body; two sides of the other end of the approach slab are connected with the connecting cable; and the waterproof and drainage facility is arranged under the approachslab. By changing the longitudinal connection position of the connecting cable and the approach slab, the elevation adjustability of the approach slab is realized and the adaptability to foundation settlement deformation is improved. The novel road and bridge approach slab has the advantages of long integral service life, high safety, small deformation, self-adaptive adjustable height differenceand easy construction and maintenance.

Description

technical field [0001] The invention belongs to the technical field of bridge construction and assembly, and in particular relates to a novel road bridge board structure and a construction method thereof. Background technique [0002] With the vigorous development of high-grade highway construction, safety, comfort and speed in the process of highway use and service are important indicators for evaluating highway quality. However, in the soft soil foundation area in the south and the loess area in the central and western regions, the bridge head jumping phenomenon is a relatively common phenomenon. [0003] Jumping at the bridge head will cause the driver and passengers in the car to bump and feel uncomfortable, which seriously affects the safety and comfort of the vehicle. At the same time, due to the sudden acceleration or deceleration of the vehicle bridgehead, it will increase traffic risks, cause traffic accidents, interrupt traffic, threaten people's life safety, and ...
