Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0024] The invention discloses a reinforcement structure for prevention and control of abutment vehicle jumping, such as figure 1 and figure 2 As shown, a reinforcement structure for the prevention and control of abutment vehicle jumping comprises a bridge 1, an abutment 2, a roadbed 14, an abutment 2 and a roadbed 14, and the abutment back roadbed 3 is set between the abutment 2 and the roadbed 14. It is characterized in that: the abutment back The subgrade 3 is evenly distributed step by step upward in the direction away from the abutment 2. The steps 8 extend upward step by step and connect with the bottom of the road subgrade 14. Between the steps 8 and the abutment 2, there is a back filler Area 10, the back filling area 10 includes stones and sandy soil, and includes a geogrid 9 that divides the back filling area 10 into several layers and is arranged...

Abstract
The invention discloses a reinforcing structure for preventing and treating jump of bridge abutment. The reinforcing structure comprises the bridge abutment, a bridge, and further comprises a abutmentback subgrade which is provided with a multi-layer steps and abutment back filler regions, wherein the abutment back subgrade is arranged by adopting high-strength ramming conducted on a deeper subgrade and then ground stabilization is conducted, the multi-layer abutment back filler regions are laid on the step foundation, geogrids are laid on step platforms and are horizontally extended to be connected with the bridge abutment, the geogrids can effectively prevent and treat the problems of water and soil loss, sedimentation and the like of the abutment back subgrade, a layer of rubber mat isarranged on the abutment back filler regions as a buffer and mainly used for preventing and treating uneven settlement, the effect of preventing and controlling the jump of the bridge abutment is remarkable, cast-in-place reinforced concrete butt straps are adopted as the butt straps, the sections of the butt straps are designed to be thicken, the backfill construction quality control of the abutment back subgrade is reinforced, the construction quality control of the roadbase pavement construction is reinforced, the compaction degree is guaranteed to meet the specification requirement, and the uneven settlement between a pavement and the bridge floor is reduced.
Description
technical field [0001] The present invention relates to a bridge head construction structure, more specifically it relates to a bridge head anti-jump construction structure. Background technique [0002] When you drive through many bridge heads, the phenomenon of "jumping" at the bridge head often occurs, which affects the comfort of driving and riding. The bridge head on the soft soil foundation is obvious, and the impact of "jumping" will further damage the structure of the bridge head, aggravating the occurrence of "jumping" at the bridge head. [0003] The patent publication number applied by China Metallurgical South City Construction Engineering Technology Co., Ltd. is: CN107905089A, and the publication date is: April 13, 2018. The invention patent discloses "a reinforced platform back for preventing bridge head jumping and its construction method", This patent uses multi-layer steps and steel wire mesh to prevent vehicle jumping caused by water damage, to realize bri...
