Embodiment Construction

[0017] See attached figure 1 , 2 3. An anti-collision type curb and sidewalk slab structure, in which a new curb 2 is poured near the sidewalk on the carriageway 1 of the bridge, and a steel bar 8 is built in the new curb stone 2, and the lower end of the reinforcement bar 8 is anchored into the carriageway 1, the anchoring part of the steel bar 8 and the roadway are anchored by planting glue 10; the upper surface of the new curb 2 is provided with a pre-embedded steel plate 3 and fixed with bolts, and the pre-embedded steel plate 3 is fixedly connected with a steel pipe handrail 4. A prefabricated sidewalk slab 6 is erected between the cantilever beam 5 of the bridge and the new curb 2. The prefabricated sidewalk slab 6 has a built-in prefabricated slab steel bar 9, and the prefabricated slab steel bar 9 is bound and connected with the steel bar 8 in the new curb stone 2.

[0018] Described new curb stone is built-in reinforcing bar 8, and the transverse structure of this re...

Abstract

The invention discloses a crash-proof type curb stone and footpath structure, which is that: new curb stones are cast near footpaths on vehicle paths on a bridge; the new curb stones are embedded with steel bars; bottom ends of the steel bars are implanted into the vehicle paths; the steel bars are implanted between the parts and the vehicle paths, and anchored with anchoring adhesive; top face of the new curb stones is arranged with pre-buried steel sheets and secured with bolts; the pre-buried steel sheets are fixed to connect with steel tube handles; precast slabs are positioned between the bridge erection beams and the new curb stones; the precast slabs are embedded with precast slab steel bars; the precast slab steel bars are bond with the steel bars inside the new curb stones. The invention also discloses a construction method for the structure. Therefore, the invention has the advantages of practical design, simple and convenient execution and easy expansion; the invention has novel bridge protection structure.

Description

technical field [0001] The invention relates to bridge protection technology, in particular to an anti-collision curb and sidewalk slab structure and a construction method thereof. Background technique [0002] In recent years, with the improvement of road conditions, the phenomenon of speeding vehicles falling out of bridges and causing mass deaths and injuries has occurred from time to time. Therefore, it is imperative to strengthen the bridge protection system. The industry recommended standard of the People's Republic of China, "Design Rules for Highway Traffic Safety Facilities" (JTG / TD81-2006), clearly stipulates the construction of new bridge safety facilities. However, there are no regulations on how to strengthen the safety facilities of existing bridges. Therefore, the strengthening technology proposed for the protection system of the built bridge has broad application prospects. Contents of the invention [0003] The purpose of the present invention is to prov...
