AI Technical Summary
Existing highway structures are prone to subsidence in geologically unstable areas, which means that repairs can only be carried out after subsidence, making it impossible to effectively guarantee normal use.
A mesh groove is provided on the foundation, in which a dense reinforcement component is laid. A crushed stone cushion layer and a leveling layer are laid on top of it to form a tightly connected structure, thereby enhancing the connection between the foundation and the crushed stone cushion layer.
By laying dense reinforcement components, the overall integrity of the highway structure is improved, the damage of geological settlement to the highway is reduced or avoided, and the service life is extended.

Description
Technical Field
[0001] This utility model relates to the field of highway technology, and in particular to a highway structure for preventing settlement. Background Technology
[0002] Highways refer to public roads between cities, between urban and rural areas, and between rural areas that are accessible to automobiles and have been inspected and approved by the transportation authorities. This includes highways that have already been built and have been certified by the transportation authorities; it also includes highways that are designed in accordance with national highway engineering technical standards and have been approved by the relevant national administrative departments and are under construction by the transportation authorities. As of the end of 2022, the total length of highways in China reached 5.28 million kilometers, of which expressways reached 169,000 kilometers and rural roads reached 4.466 million kilometers.
[0003] my country has a vast territory, and many areas have unstable geology, making highways prone to settlement. Currently, highway settlement prevention technology mainly relies on monitoring, and it is difficult to add settlement prevention measures to the highway structure. As a result, highways can only be repaired after settlement, which cannot effectively guarantee the normal use of highways.
[0004] Therefore, there is an urgent need for a road structure that can prevent settlement and solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a road structure that prevents settlement, so as to solve the problems existing in the prior art.
[0006] To achieve the above objectives, this utility model provides the following solution:
[0007] This utility model provides a road structure for preventing settlement, including a foundation, a mesh groove provided on the foundation, a grid compaction reinforcement component laid in the mesh groove, the top of the grid compaction reinforcement component being higher than the top of the foundation, a crushed stone cushion layer laid on top of the foundation, a leveling layer laid on top of the crushed stone cushion layer, and a surface layer laid on top of the leveling layer.
[0008] Preferably, the compaction coefficient of the foundation is greater than 0.97.
[0009] Preferably, geotextile is laid between the foundation, the grid compaction reinforcement component, and the crushed stone cushion layer.
[0010] Preferably, the grid compaction reinforcement component includes an outer frame, with baffles inside the outer frame and compaction filler between the baffles.
[0011] Preferably, the top of the grid compaction reinforcement component is 10-20cm higher than the top of the foundation.
[0012] Preferably, the thickness of the crushed stone cushion layer is 40-80cm.
[0013] Preferably, drainage channels are provided on both sides of the surface layer.
[0014] The present invention achieves the following beneficial technical effects compared to the prior art:
[0015] This utility model provides an anti-settlement highway structure, including a foundation with a mesh groove. A grid-reinforced component is laid within the mesh groove, with its top higher than the top of the foundation. A crushed stone cushion layer is laid above the foundation, followed by a leveling layer, and then a surface layer. By laying the grid-reinforced component within the mesh groove, a tight connection between the foundation and the crushed stone cushion layer is formed, thereby improving the overall integrity of the highway structure, reducing or preventing damage from geological settlement, and effectively extending the highway's service life.
