The utility model discloses reduce the settling amount of road bed, improved the security that the highway was driven a vehicle.
Description
Technical field
The utility model relates to highway construction field, specifically a kind of Anti-settling device of highway subgrade.
Background technology
Develop rapidly along with socioeconomic, speedway obtains great development at home, define the freeway net radiation whole nation interweaved in length and breadth gradually, subgrade settlement is a kind of phenomenon endangering traffic safety common in highway use procedure, highway is owing to bearing higher load effect for a long time, cause roadbed integral sinking, road surface is uneven, when vehicle travels on such road surface, there is higher safety problem, and existing anti-settling measure is lay waterproofing course between roadbed and roadbed stake mostly, this measure is difficult to the problem solving roadbed subsidence thoroughly, especially in the location that geologic condition is poor.
Utility model content
The purpose of this utility model is to provide a kind of Anti-settling device of highway subgrade, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of Anti-settling device of highway subgrade, comprise supercrust, water barrier, base course, geogrids layer, roadbed stake, medium-sand seam, geo membrane layers, reinforced pipe, clamping plate and pretension bolt, the below of described supercrust is provided with water barrier, the middle position of water barrier is provided with geo membrane layers, the water barrier of the top of described geo membrane layers and the water barrier of below are all filled with medium-sand seam, the below of described water barrier is provided with base course, three layers of geogrids layer are provided with in base course, and be provided with reinforced pipe between adjacent geogrids layer, the two ends of described reinforced pipe are fixed on clamping plate by pretension bolt, the below of described base course is fixed with roadbed stake.
Preferably, the length of described reinforced pipe is greater than the width of base course.
Preferably, described reinforced pipe has three layers, arranges in inverted right-angled triangle.
Preferably, the bottom of described roadbed stake is curved.
Compared with prior art, the beneficial effects of the utility model are: this Anti-settling device of highway subgrade, prevent the ponding of supercrust from infiltrating base course by the geo membrane layers in water barrier and medium-sand seam, reduce the settling amount of roadbed, in base course, geogrids layer is set, the supporting capacity of base course can be improved, thus reduce the settling amount of roadbed, reinforced pipe is provided with between adjacent geogrids layer, and reinforced pipe has three layers, arrange in inverted right-angled triangle, the side of base course is reinforced to the lateral sliding preventing base course, thus reduce the sedimentation of base course, be fixed with roadbed stake in the below of base course simultaneously, the bottom of roadbed stake is curved, the load of base course is shared by roadbed stake, thus reduction subgrade settlement, improve the safety of highway driving.
