A Quantitative Detection and Treatment Method for Vehicle Jumping Disease at Bridge Head

Abstract

The invention discloses a quantitative detection and treatment method of bridge-head bumping defects. The method comprises a detection stage and a treatment stage. Firstly, the practical results of elevation measurement are used as the basis for judging whether the bridge-head bumping defects exist or not; then, through the setting of measures of reverse slope lines, secondary pull slope lines, circular arc connection lines, variable slope point two-side slope difference limitation and the like, the smooth connection of the design ground line is ensured. The detection method is simple and scientific; the real states of the bridge-head bumping can be quantificationally described; in addition, the bridge-head bumping defects are scientifically treated according to the detection results; theconditions of bridge-head bumping of highway bridges can be well avoided; the vehicle driving comfort and safety are ensured. The judgment on whether the bridge-head bumping exists or not is more scientific, the occurrence of secondary bumping phenomenon near an expansion joint due to further compaction of newly laid asphalt mixture is reduced to the maximum degree; the stability and the durability of the bridge head pavement structure are ensured; the method can be widely applied to the judgement and treatment of the high-grade highway bridge bridge-head bumping.

Description

technical field [0001] The invention relates to the technical field of highway maintenance, in particular to a method for quantitative detection and treatment of vehicle jumping diseases at bridgeheads. Background technique [0002] In recent years, my country's transportation industry has developed rapidly, and the mileage of expressways has increased day by day. With the improvement of highway grades, structures such as culverts, passages, and bridges account for an increasing proportion of highway mileage, with an average of 2-3 structures per kilometer. A series of problems associated with expressways have also caused widespread concern Pay attention, the phenomenon of jumping at the bridge head is one of them. The bridge head jumping phenomenon refers to the uneven settlement of structures such as bridges and culverts and the back of the abutment under the action of continuous traffic load and self-weight, resulting in bridge head steps appearing on the road surface at...
