Description
Technical field
It the utility model is related to building structure technology field, more particularly to a kind of filling roadbed road surface knot of argillaceous siltstoue
Structure.
Background technology
Argillaceous siltstoue is met water and is easily softened, so that easy collapse phenomenon.Traditional pavement structure is set on roadbed
Asphalt base course, pitch middle level and asphalt surface course, roadbed do not do waterproofing protection, and water is easily entered in roadbed, have shale powder
The roadbed of sandstone easily causes road surface to form collapse phenomenon after water is met, and not fine for argillaceous siltstoue roadbed at present
Treatment measures, effectively to prevent collapse phenomenon.
Utility model content
The purpose of this utility model is to provide a kind of filling roadbed pavement structure of argillaceous siltstoue, can improve pavement structure
Stability, effectively solve the problems, such as that road surface collapses.
To achieve the above object, the utility model provides a kind of filling roadbed pavement structure of argillaceous siltstoue, including roadbed
With positioned at the ditch of roadbed both sides, it is characterised in that：The top of the roadbed is sequentially equipped with impervious barrier, bed course, steady from the bottom to top
Given layer, asphalt base course, pitch middle level, asphalt surface course, ditch bottom is in roadbed side down at 70cm, in impervious barrier to ditch bottom
Ditch inner wall, outer wall and bottom wall are equipped with impervious concrete, and guide system is collected in the infiltration that impervious barrier includes from top to bottom sequentially arranging
System, geotextiles, HDPE film and GLC pads, bed course are collected above guide system positioned at infiltration, and GLC pads above roadbed, receive by infiltration
The pipeline of vertical and horizontal distribution is embedded with collection guide system, the pipeline of lateral arrangement is stretched into the ditch of both sides, in both sides water
Planting area is respectively equipped with the inside of ditch, the bottom of planting area extends to stabilized zone, and top and the asphalt surface course of planting area are put down
Together.
As further improvement of the utility model, the infiltration is collected guide system and is made of impermeable clay, longitudinal direction
It is embedded in the pipeline of cross direction profiles in impermeable clay.
As further improvement of the utility model, the bed course is made of sandstone powder and cement mixing, the stabilized zone
It is made of rubble and cement mixing.
Emulsified asphalt oil is equipped with as further improvement of the utility model, between the pitch middle level and asphalt base course,
Antiseepage emulsified asphalt is equipped between asphalt surface course and pitch middle level.
Compared with prior art, the argillaceous siltstoue of the utility model filling roadbed pavement structure has the beneficial effect that：
(1) using the above structure, avoid water to penetrate into roadbed, meet water softening so as to avoid silty rock mass, prevent
Road surface collapses.
It will be become more fully apparent by following description and with reference to attached drawing, the utility model, these attached drawings are used to explain this
The embodiment of utility model.
Brief description of the drawings
Fig. 1 is the schematic diagram of the filling roadbed pavement structure of argillaceous siltstoue.
Embodiment
The embodiment of the utility model described referring now to attached drawing, similar element numbers represent similar member in attached drawing
Part.
Please refer to Fig.1, the filling roadbed pavement structure of the argillaceous siltstoue includes roadbed 1 and positioned at 1 both sides of roadbed
Ditch 2, the top of the roadbed 1 are sequentially equipped with impervious barrier 3, bed course 4, stabilized zone 5, asphalt base course 6, pitch middle level from the bottom to top
7th, asphalt surface course 8,2 bottom of ditch in 1 side of roadbed down at 70cm, impervious barrier 3 to the ditch inner wall at 2 bottom of ditch, outer wall and
Bottom wall is equipped with impervious concrete 9, avoids water from being penetrated at ditch in roadbed 1, prevents road surface from collapsing.In the inner side of both sides ditch 2
Planting area 10 is respectively equipped with, the bottom of planting area 10 extends to stabilized zone 5, top and the asphalt surface course 8 of planting area 10
Concordantly, trees or other plant, aesthetic road can be planted.
Guide system 31, geotextiles 32, HDPE film 33 are collected in the infiltration that the impervious barrier 3 includes from top to bottom sequentially arranging
With GLC pads 34, bed course 4 collects the top of guide system 31 positioned at infiltration, and GLC pads 34 are located at the top of roadbed 1, and guide system is collected in infiltration
The pipeline 311 of vertical and horizontal distribution is embedded with system 31, the pipeline 311 of lateral arrangement is stretched into both sides ditch 2.The infiltration
Collect guide system 31 to be made of impermeable clay, the pipeline 311 of vertical and horizontal distribution is embedded in impermeable clay.HDPE film
33 be high density polyethylene (HDPE) antiseepage film, with barrier properties are good, chemical stability is good, mechanical strength is higher, climate adaptability is strong, make
The features such as with long lifespan.GLC pads 34 are geosynthetics bentonite pads, are to press from both sides bentonite in powder between two layers of geosynthetics
Last (or other low permeability materials), are mainly used for sealing and antiseepage.The design of guide system 31 is collected by seeping water so that water
Infiltration collection guide system 31 will not be passed through and penetrate into geotextiles 32, geotextiles 32 are penetrated on a small quantity even if having, also due to geotechnological
