Technical field
It the utility model is related to highway construction technical field, more particularly to a kind of Anti-settling device of highway subgrade.
Background technology
Subgrade settlement is phenomenon of the highway using a kind of common harm traffic safety of process, higher due to bearing for a long time
Load acts on, and causes roadbed integral sinking, formation is uneven, and vehicle on this up-and-down road surface when travelling, really
It is that driving is big to avoid.And existing anti-settling facility is only that one layer of process layer is laid between the basic unit of roadbed and roadbed stake,
Excessively simple structural measure is difficult to thoroughly solve the problems, such as roadbed subsidence, is especially built in the poor location of geological conditions
Road, carries out that anti-settling measure is particularly important, and in existing pavement structure, the change between each functional layer for load does not have
There is the coordination ability, and because differential settlement occurs in the influence of underground and surface water, thus early damage occurs respectively,
The service life reduction of pavement structure can be caused.
Utility model content
The purpose of this utility model is for overcome the deficiencies in the prior art, there is provided a kind of highway subgrade anti-settling is set
Apply, enhance subgrade rating and resistance capacity to deformation, further improve the anti-settling effect and stability of roadbed, and roadbed
With water proofing property, Road Service Life is extended, improves travel safety.
The utility model is achieved through the following technical solutions：A kind of Anti-settling device of highway subgrade, including supercrust, coagulation
Soil layer, base course, the upper surface laying supercrust of the concrete layer, the bottom of concrete layer sets base course, the roadbed
Layer includes top rammed earth layer, middle part rammed earth layer, bottom rammed earth layer, and some support posts are set in the base course, described
The surface of support post sets resistance to compression bar, and support matrix is set in the bottom of base course.
Further, the surface of the base course is provided with membrane waterproofing.
Further, the bottom rammed earth layer, middle part rammed earth layer, top rammed earth layer stack successively from top to bottom, and the bottom of at
Geogrids layer is provided between portion's rammed earth layer and middle part rammed earth layer between middle part rammed earth layer and top rammed earth layer.
Further, the upper end support concrete layer of the support post, the lower end of support post is connected to bottom rammed earth
The lower surface of layer.
Further, the resistance to compression bar is the obliquity rod arranged obliquely, and resistance to compression bar is symmetricly set on support post
Both sides.
Further, the support matrix has been evenly arranged several in the bottom surfaces of base course, and every piece of support matrix
For isosceles trapezoid.
Compared with prior art, the beneficial effects of the utility model are：Roadbed layer surface of the present utility model is wrapped up
Membrane waterproofing, roadbed has water resistance, while base course is made up of multilayer rammed earth layer, and geotechnological lattice are arranged between rammed earth layer
Gate layer, the geogrids layer of arrangement add base course entire firmness, improve roadbed resistance capacity to deformation, prominent be
More support posts, and the upper end support concrete layer of support post are provided with base course, lower end is connected to bottom rammed earth layer
Lower surface, support post adds the anti-bearing capacity of base course, while is arranged symmetrically in the surface both sides of support post oblique
On resistance to compression bar, the ability that there is resistance to sink to base course, further improve the anti-settling effect of roadbed, while also on road
The bottom of basic unit has been evenly arranged the support matrix of several isosceles trapezoids, and support matrix can be by the load from base course point
It is scattered on broader underlayment, further enhancing subgrade rating, subgrade stability is good, extends Road Service Life, carries
High travel safety.
