Transition structure for preventing bumping at bridgehead and using method thereof

Abstract

The invention discloses a transition structure for preventing bumping at a bridgehead and a using method thereof. The transition structure comprises a fixed unit and a plurality of adjusting units, wherein the fixed unit comprises a separation groove, a slope and a settlement joint, the separation groove is located between an abutment and a road section, the slope is located in the separation groove, and the settlement joint is located between the slope and the road section; each adjusting unit comprises a stand column and a plurality of triangular building blocks, and each stand column is composed of a plurality of stand column blocks; the plurality of adjusting units are arranged in the separation groove, the lower end of the stand column of each adjusting unit penetrates through the slope, and a plurality of triangular building blocks are arranged on each stand column; and the top surfaces of the plurality of adjusting units are flush with the surface of the abutment, so the abutment and the road section are in smooth transition. According to the invention, when continuous settlement happens to the road section and the amount of settlement is large each time, only part of the triangular building blocks and the stand column blocks on each stand column need to be taken away, so the abutment and the road section can be in smooth transition again, and the phenomenon of bumping at the bridgehead is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a transitional structure for preventing vehicle jumping at the bridge head and a use method thereof. Background technique [0002] Vehicle jumping at the bridge head refers to the phenomenon that due to the different degrees of subsidence and fracture of the road surface at the backfill of the abutment, the vehicle will jump and impact when passing, thereby causing additional impact loads on the bridge culvert and the road surface. Jumping at the bridge head makes the driver and passengers feel bumpy and uncomfortable, and even causes the vehicle to slow down significantly, which can lead to serious traffic accidents, especially vehicle mechanical accidents. Therefore, the problem of vehicle jumping at the bridge head has become an important factor affecting the engineering quality and cost of high-grade highways. [0003] The main causes of vehicle jumping at the br...

AI Technical Summary

Problems solved by technology

[0004] Effectively solving the problem of vehicle jumping at the bridge head has always been one of the problems that plague management engineers and technicians. At present, soft soil foundation reinforcement, consolidation methods, support methods, and pavement methods are generally used, but it is difficult to fundamentally solve the problem. The construction period is too long, the cost is too high, etc.

[0005] Because the height of the staggered platform increases with time, the bridge head after the treatment is prone to the phenomenon of bridge head jumping again, so frequent maintenance and adjustment are required. Therefore, the existing methods for solving bridge head jumping generally have the problems of difficult implementation and frequent maintenance.
