Problems solved by technology

[0003] At present, bridges erected on rivers or lakes often install some guardrails in order to prevent motor vehicles and non-motorized vehicles from falling off the bridge deck. Most of the existing guardrails are low fences. For motor vehicles such as buses, the protection is not enough

Embodiment 1

[0035] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device provided at the support of the abutment.

Embodiment 2

[0050] The embodiment of the present invention is further limited on the basis of embodiment 1.

[0051] see figure 2 and image 3 A reinforcing plate structure 32 is installed on the guardrail 3 outside the lifting rod 23 , and the lower end of the reinforcing plate structure 32 is connected to the lifting rod 23 .

[0052] Furthermore, when the reinforcing plate structure 32 rises with the lifting rod 23, it can provide secondary protection to avoid the problem that the lifting rod 23 is not sufficiently protected due to excessive impact force.

[0053] The guardrail 3 is provided with a receiving groove 33 in conjunction with the reinforcing plate structure 32 , and the reinforcing plate structure 32 is stored inside the receiving groove 33 , and the lower end of the receiving groove 33 communicates with the cavity 31 .

[0054] The reinforcing plate structure 32 is provided with a reinforcing plate 35 , and a connecting rod 36 is fixed at the bottom of the reinforcing pla...

Abstract

The invention belongs to the field of bridges, and particularly relates to a rising type bridge protection wall based on impact, which comprises two mounting walls reinforced on a bridge subgrade anddistributed on two sides of the bridge subgrade respectively, and further comprises a protection fence fixed at the upper ends of the mounting walls, wherein a plurality of lifting rod structures distributed at equal intervals are arranged on the protection fence, an extrusion structure matched with the lifting rod structures is installed on the surface, close to one side of a bridge roadbed, of the protection fence, a push block with the cross section in a right trapezoid shape is arranged on the extrusion structure, and an outer impact plate is fixed to the outer portion of the push block through an inner push rod. When the outer impact plate is impacted, the pushing block is pushed inwards through the inner pushing rod, the pushing block with the right-angled trapezoidal cross section pushes the lifting rod structure upwards through the inclined face of the pushing block, the lifting rod structures extend out of the protection fence, rising of the wall during impact is achieved, strong protection can be conducted on motor vehicles such as some tall buses, and the safety coefficient is high.
