Description

A kind of Gang Qiao

Technical field

The utility model relates to a kind of basic means of transportation, is specifically related to a kind of Gang Qiao that can be used for flyover crossing as the upper strata road.

Background technology

Along with Chinese economic development, the various vehicles rapidly increase, and thus, have brought great pressure to urban traffic.For improving this situation, various places are strengthened the input that traffic infrastructure is built one after another, be used for newly-built road, original road is carried out reorganization and expansion etc., wherein, a most outstanding variation is no more than being flyover crossing with a large amount of level crossing reconstructions on the urban traffic trunk line.

Flyover crossing can make the wagon flow of each main travel direction be independent of each other, and can alleviate traffic pressure to a great extent.But existing flyover crossing is in process of construction, and bridge pier need adopt on-the-spot pouring, and bridge plate, crossbeam etc. are also many to water construction at the scene with bridge pier.Therefore, there is following weak point in existing flyover crossing, needs to be resolved hurrily.One, because each main member needs on-the-spot pouring, existing overpass bridge not only want closure construction, and construction period is longer when building.During this period, all contact vehicles all need detour, and make nervous more with regard to obstructed traffic originally.Two, this long-time, large-scale site operation, the huge and expensive costliness of engineering is unfavorable for extensive popularization, is restricting the improvement as early as possible of urban traffic conditions.

Summary of the invention

At the deficiency of prior art scheme, technical problem underlying to be solved in the utility model is that a kind of Gang Qiao that can shorten the flyover crossing site operation cycle is provided.

The technical solution adopted in the utility model is, Gang Qiao comprises bridge pier, bridge plate, crossbeam and guardrail, this Gang Qiao is a fabricated structure, is equipped with location structure between each individual member, and each individual member is provided with corresponding fixed connection structure respectively at itself and other individual member place of linking.

The bridge pier of this Gang Qiao can segmentation form several individual members, and its epimere and crossbeam are one-body molded, is an individual member.

Can be between each individual member of this Gang Qiao by projection and groove location.

The fixed connection structure of described Gang Qiao can be the embedded iron of being located on each individual member, is coupled to each other together by the embedded iron welding between each individual member.

Compare with traditional flyover crossing, each individual member of Gang Qiao described in the utility model can prefabricatedly be processed, split transportation, assembled on site, and easily realizes standardization and seriation, is convenient to construction and management.This Gang Qiao can directly be assembled in the road bed after strong processing, can shorten the engineering construction cycle of flyover crossing greatly, saves engineering cost.
