Prefabricated jacking box culvert provided with steel blade corners

Abstract

The invention discloses a prefabricated jacking box culvert provided with steel blade corners. The prefabricated jacking box culvert comprises a box culvert main body structure, the steel blade corners and a prefabricated bottom plate flange plate, wherein the box culvert main body structure comprises a bottom plate, a top plate and a web plate and is connected with the steel blade corners and the prefabricated bottom plate flange plate by using high-strength bolts. The box culvert main body structure, the steel blade corners and the prefabricated bottom plate flange plate are all prefabricated by a factory and are assembled on site, so the construction progress can be quickened and the construction period can be shortened. Meanwhile, the contact area of the box culvert main body structure and a soil body is increased, pressure stressed by the soil body is reduced, the settlement of the box culvert main body structure is effectively reduced, and head embedding in a jacking process of the box culvert main body structure is avoided. Besides, the jacking direction can be adjusted by changing the soil cutting direction of the steel blade corners to guarantee correct positioning of the box culvert main body structure. Thus, a new technological choice with superior performance is provided for the box culvert jacking construction, the box culvert is to be widely applied with the prosperous development of traffic engineering, and obvious social and economic benefits are produced.

Description

Technical field [0001] The present invention belongs to the construction field of the flat intersection. Background technique [0002] In recent years, my country's modernization construction has developed rapidly, and the size of the city has also expanded.However, at the same time, the construction of most urban infrastructure failed to keep up with the development of the city in a timely manner. The crowded traffic and the blockage of traffic have become one of the iconic phenomena of most cities. As a result, urban economic development has also been seriously affected and restricted.Among them, a large number of railways and highways existing in many cities have become the "bottlenecks" one by one, which is an important reason for urban traffic jams.At the same time, due to the sharp increase in driving density after the speed of the train, it caused a large number of hidden safety hazards in highway and railway crossing.Therefore, the three -dimensional transformation of h...

Problems solved by technology

[0006] technical problem: In order to overcome the problems of subsidence, "head-stuck" phenomenon and jacking direction control problems that often occur in the case of weak foundation bearing capacity of existing jacking box culverts, the present invention provides a box culvert that can greatly reduce the settlement and Prefabricated jacking box culverts with steel edge angles can effectively avoid the phenomenon of box culverts being “stuck” and control the jacking direction of the box culverts to ensure that the box culverts are finally positioned accurately.
