Embodiment Construction
[0060] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the advantages of the present invention are clearer and easier to understand through the description.
[0061] Considering the limitations of the subgrade pavement structure and the corresponding reinforcement measures on the embankment-crossing pipeline, the patent of the invention is based on different working conditions, and comprehensively considers the equivalent load effect of the current embankment-crossing pipeline before and after road construction, and proposes a For the subgrade pavement structure above the embankment pipeline, reasonable load reduction and reinforcement measures are adopted for the existing pipeline to reduce the probability of damage to the embankment pipeline and roadbed pavement disease, improve the service life...

The invention discloses a roadbed and pavement structure located on an embankment penetrating pipeline, and relates to the field of road engineering. The structure comprises a roadbed pavement structure and an embankment penetrating pipeline; the roadbed pavement structure is located on the embankment penetrating pipeline and has four working conditions. Based on different working conditions, the roadbed and pavement structure located above the embankment penetrating pipeline is provided according to the principle that the embankment penetrating pipeline structure has the same load effect before and after a newly-built road, and a basis is provided for load shedding and reinforcing design of an existing embankment penetrating pipeline. The invention further relates to a construction method of the roadbed pavement structure located on the embankment penetrating pipeline.
Description
technical field [0001] The invention relates to the field of road engineering, more specifically, it relates to a subgrade pavement structure located on a pipeline crossing an embankment. The invention also relates to the construction method of the subgrade pavement structure on the embankment crossing pipeline. Background technique [0002] During the construction of the Binjiang road, it is inevitable that the proposed road will intersect with the embankment pipeline. Since most of the current embankment pipelines have not considered the high-frequency heavy-duty vehicle conditions in the design process, the road construction and later operation During the process, under the action of vehicle loads (especially high-frequency heavy loads), the uneven settlement of the filled embankment will lead to frequent occurrence of road surface diseases and damage to the pipelines passing through the embankment, which will affect the normal use of the pipelines. There are hidden dang...
