A road structure with a road section containing structures and its construction method

Abstract

The invention provides a road structure of a structure-containing road section and a construction method of the road structure. The structure is that a first filling body, a second filling body, a third filling body and a fourth filling body are sequentially arranged at the upper part of a roadbed soil body on the outer side of a road culvert pipe; a fifth filling body is arranged at the lower part of the road culvert pipe; bearing pier bodies are hit in the roadbed soil body from the first filling body; the second filling body, the fourth filling body and the fifth filling body are respectively internally provided with a first deformation control pipe, a second deformation control pipe and a settlement control bag; a pipe side connecting body and a deformation coordination plate are respectively arranged at the intersections between the road culvert pipe and the third filling body and between the road culvert pipe and the fourth filling body; a pipe side inclined strut is arranged between the road culvert pipe and the deformation coordination plate, and a force cell is arranged on the pipe side inclined strut. By adopting the road structure and the construction method of the roadstructure provided by the invention, not only is the bearing capacity of a road improved, but also the differential settlement of the road surface is controlled.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a road structure and a construction method for a road section containing structures that can effectively coordinate difference variables of road sections containing structures, improve the driving environment of road vehicles, and save road maintenance costs. Background technique [0002] With the rapid development of our country's economy, the construction of road engineering has expanded rapidly. Road sections containing structures are often encountered in the process of road engineering construction. In the road sections containing structures, due to the small weight of the structures themselves, under the action of vehicle loads in the later stage, differential deformations are likely to occur at the back of the abutment, which seriously affects driving.

AI Technical Summary

Problems solved by technology

Road sections containing structures are often encountered in the process of road engineering construction. In the road sections containing structures, due to the small weight of the structures themselves, under the action of vehicle loads in the later stage, differential deformations are likely to occur at the back of the abutment, which seriously affects driving. Safety

[0003] At present, for the construction method of the differential deformation of the abutment back, the grouting of the abutment back section or the use of pavement materials is usually used as a substitute. Although this method can restore the smoothness of the road surface to a certain extent, it does not effectively reduce the The additional stress of the foundation, on the contrary, increases the additional stress of the foundation; at the same time, the road section of the structure has not been effectively dealt with, and its own gravity is still smaller than that of the general road section, and the difference between it and the general road section is increased

After these methods restore the flatness of the road section behind the platform, the differential deformation still exists in the later stage, and the problem has not been effectively solved

[0004] To sum up, although some existing construction methods of controlling differential deformation can improve the smoothness of the road surface to a certain extent, there are still room for improvement in issues such as differential deformation and deformation coordination control.
