Technical Field
The utility model relates to road engineering technical field, more specifically the road bed differential settlement prevention and cure structure that road and dyke combined that says so.
Background
With the advancement of the national urbanization process and the development and utilization of the urban beaches and rivers, the construction mode of combining urban roads and dikes is gradually popularized. Embankment bonding is usually to perform treatments such as widening and heightening on the existing embankments. Under the action of traffic load, uneven settlement and even longitudinal cracks are easy to generate between the original dike and the newly-built roadbed. The generation of the above-mentioned diseases will affect the driving safety and the service life of the road. Therefore, a structure for preventing and controlling the uneven settlement of the roadbed combining the road and the dike is urgently needed.
At present, researches and reports on a road surface structure combined with an embankment and a non-uniform settlement prevention and treatment technology thereof are rare, and related technical guidance is also lacked in related road and water conservancy regulations. Therefore, it is necessary to develop a technique for overcoming the above-mentioned problems.

The utility model aims at being implemented through the following technical scheme: a road and dike combined roadbed differential settlement prevention structure comprises a proposed road, a current dike, a road surface structure, a sandy soil layer and a three-way geogrid;
the proposed road is arranged on the side of the back river, the current dike is arranged on the side close to the river, and the proposed road is in contact with the current dike;
a sandy soil layer, a pavement structure and the pavement structure of the road positioned at the top are sequentially arranged above the proposed road;
the dike steps are positioned on the side of the back river of the existing dike, and the three-way geogrids are arranged at the top of each dike step, the bottom of the sandy soil layer and the top of the sandy soil layer.
In the above technical scheme: the proposed road is positioned at the back river side of the existing dike, and the elevation of the proposed road is not lower than that of the existing dike.
In the above technical scheme: the sandy loam layer is positioned in the depth range from the bottom of the pavement structure to the position below the current embankment by 1.5 meters.
In the above technical scheme: the height of the embankment steps is 0.5 m.
In the above technical scheme: the width of the three-way geogrid arranged at the depth of 1.5 meters below the pavement structure and the existing dike is not less than the width of the pavement structure.
In the above technical scheme: the width of the three-way geogrid positioned at the upper part of the embankment step is 5 meters.
In the above technical scheme: the ultimate tensile strength of the three-way geogrid is not less than 50kN/m, and the tensile strength at 2% elongation is not less than 20 kN/m.
The utility model has the advantages of as follows: the utility model discloses can effectively coordinate the embankment and combine the inhomogeneous settlement of form road bed, avoid producing the road surface crack to influence driving comfort level and security.
