Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] refer to figure 1 with figure 2 , the present invention is a high-steep embankment reinforcement structure to prevent uneven settlement, including embankment fill 5 on both side slopes with large topographical undulations. Reinforcing piles 4 are arranged longitudinally and laterally at intervals in the embankment filling 5, and the lower parts of each reinforcing pile 4 are anchored in the embankment filling 5 to reinforce the embankment filling, so that the filling forms an overall force and avoids the loss of the overall lateral stiffness of the embankment. difference. A rigid structure layer 3 is arranged on the top surface of the embankment filling 5, and the rigid structure layer 3 is consolidated with the pile tops of the reinforcement piles 4 to effectively control the displacement of the pile tops of the reinforcement piles 4 and impr...

Abstract

The invention relates to a high and steep embankment reinforcing structure preventing differential settlement, and a base reinforcing structure suitable for high and steep embankments with large hypsography on two sides. A reliable retaining structure is provided for high and steep embankments for mountain areas, large differential settlement is effectively avoided, and the operation comfortability of highways or high-speed railways is improved, so that safety accidents are avoided. The high and steep embankment reinforcing structure comprises an embankment fill to be filled and constructed to slops with large hypsography on two sides, reinforcing piles are longitudinally and laterally arranged at intervals in the embankment fill, and the lower parts of the reinforcing piles are anchored in the embankment fill. A rigid structural layer is arranged on the top surface of the embankment fill, and is consolidated with the pile tops of the reinforcing piles. A bed layer is filled above the rigid structural layer, and a pavement structure is built on the bed layer.

Description

technical field [0001] The invention relates to a reinforcement structure for railway and highway subgrades, in particular to a reinforcement for high and steep embankments that reduces uneven settlement. Background technique [0002] In recent years, infrastructure construction has entered a period of rapid development, and large-scale construction of railways and highways. Railways and highways located in mountainous areas, due to the dramatic ups and downs of the terrain, inevitably require embankment filling on steep slopes. In low-lying landforms, due to long-term water catchment or farmland planting needs, weak foundations are often formed, and their settlement is much greater than that of embankments on the higher side. [0003] At present, the design speed of railways and highways has been greatly improved. The higher design speed not only needs to control the overall settlement of the embankment, but also the uneven settlement of the embankment is also a factor that...
