Highway bridge reinforced flexible anti-collision wall and construction method thereof

Abstract

The invention provides a highway bridge reinforced flexible anti-collision wall and a construction method thereof. The highway bridge reinforced flexible anti-collision wall comprises an anti-collision wall body, a steering wheel, a plurality of prestressed steel strands, a signal transmitting device and a strain sensor. A tensioned prestressed steel strand is arranged on one side of the anti-collision wall body in the longitudinal direction, a steering wheel is rotationally arranged on the prestressed steel strand in a penetrating mode, and a strain sensor is arranged on the prestressed steel strand. The strain sensor is used for acquiring a strain value of the prestressed steel strand and transmitting the strain value to the signal transmitting device; the signal transmitting device transmits the strain value of the prestressed steel strand to a receiving terminal of a traffic management center, and when the strain value of the prestressed steel strand is larger than a preset threshold value, the receiving terminal triggers an alarm mechanism. When the anti-collision wall is collided by a vehicle, the strain value of the steel beam suddenly changes, and an early warning mechanism is excited, so that the emergency disposal efficiency of a traffic management center on road traffic accidents is improved, the accident rescue capability can be remarkably improved, and the intelligent management level of a road can be improved.

Description

technical field [0001] The invention belongs to the field of bridge engineering, and in particular relates to a reinforced flexible anti-collision wall for highway bridges and a construction method thereof; the invention is suitable for high-pier bridges on high-grade highways that span deep water, deep valleys, and have a relatively large clearance under the bridge. Background technique [0002] In recent years, with the continuous advancement of my country's infrastructure construction, high-pier bridges spanning deep valleys, reservoir areas, rivers, and oceans continue to emerge. Bridge traffic safety facilities should also keep pace with the times to cope with complex and heavy traffic conditions. As the most important bridge traffic safety facility, the bridge anti-collision wall has become particularly necessary to improve its function and protection level. In order to prevent vehicles that deviate from the driving route from rushing out of the bridge deck when an acc...
