Abstract
The invention provides a filling roadbed structure which comprises a roadbed, wherein a stone square cushion layer is laid at the bottom of the outer side of a roadbed side slope, soil and stone mixed fillers are filled above the stone square cushion layer and the roadbed side slope to form a filling side slope, the slope ratio of the filling side slope is less than or equal to 1:4.0, and the stone square cushion layer and the soil and stone mixed fillers on the outer side of the roadbed jointly form a protection system to protect a conventional roadbed and serve as a foundation of slope soil. The method solves the problems of high protection cost, no environmental protection, large accident loss, high cost for building and abandoning the slag yard and the like of the traditional filling roadbed. The invention belongs to the technical field of roadbed construction.
Description
Technical field
The present invention relates to a kind of road structures, belong to roadbed and construct technical field.
Background technology
In highway engineering construction, especially in mountain area place, subgrade engineering generally has excavation section and embankment section.
In filled-up ground, height of embankment is in 20m or less, by 1:1.3~1:1.75 slope ratio fills the cubic metre of earth and stone.Then on the outside of side slope
Using dry stone pitching or use frame gird type slope protection.
Traditional filled-up ground design is only from the angle for considering subgrade stability, safety of the roadbed side slope in code requirement
It can keep stablizing under coefficient.In this case the Slope obtained is bigger, and usually 1:1.5, while to prevent water and soil
Be lost in, the safeguard procedures such as sash beam or loose stone need to be sets in slope surface, these safeguard procedures it is costly and not environmentally, lack and give birth to
Machine.Accident occurs for vehicle when going out guardrail, since grade of side slope is big, and does not have secondary protection measure, suffers heavy losses, usually vehicle is ruined
People dies.
In addition in roadbed earthwork, especially mountain area place, the cubic metre of earth and stone are often difficult to balance, and digging soil is more, needs
Dumping Sites are built in additional expropriation of land, and cinder field protection is costly.
Invention content
It is an object of the invention to：A kind of filled-up ground structure and its construction method are provided, to solve traditional filled-up ground
Protect that costly, not environmentally protective, causality loss is big, builds the problems such as Dumping Sites are costly.
To solve the above problems, quasi- use such a filled-up ground structure, including roadbed, the bottom on the outside of roadbed side slope
Cubic meter of stone bed course is equipped with, filled with earth-rock mixture object to form embankment side slope, embankment side above the side slope of cubic meter of stone bed course and roadbed
The slope ratio on slope is less than or equal to 1:4.0, embankment cubic meter of stone bed course, earth-rock mixture object collectively constitute guard system on the outside of roadbed, and protection is normal
Roadbed is advised, while as the basis of Soil Slope.
In aforementioned filled-up ground structure, the side slope top of the slope of roadbed is provided with guardrail；
In aforementioned filled-up ground structure, Soil Slope is equipped on earth-rock mixture object, being planted on Soil Slope there are trees, sets
Wood is ascended a height plantation, and green coverage is increased, and is conducive to build environment-friendly type highway；Top of the slope guardrail, very slow embankment side slope and tree
The collective effect of wood, can substantially reduce the loss that traffic accident is brought；
In aforementioned filled-up ground structure, cubic meter of stone bed course and earth-rock mixture object are the digging soil excavated section and generated, cubic meter of stone bed course
It is required that being compacted by particular requirement according to certain grading, native stone mixture is stacked by waste requirement, can be turned waste into wealth, and is reduced cinder field and is held
Amount even can avoid setting cinder field, to investment reduction；
In aforementioned filled-up ground structure, Soil Slope derives from the clear table of roadbed, is not required to additionally fetch earth.
The construction method of above-mentioned filled-up ground structure is as follows：
A. satisfy the need the clear table of base face progress, and clear table soil is concentrated and is stacked, so that the later stage uses as Soil Slope；
B. when ground horizontal slope is larger, geology step is excavated by code requirement, to ensure the stabilization of conventional roadbed；
C. according to compaction requirement routinely roadbed side slope slope than placement in layers routine roadbed, while construct cubic meter of stone bed course and
Earth-rock mixture object, cubic meter of stone bed course are compacted by the requirement not less than conventional roadbed, earth-rock mixture object routinely waste mode with routine
Roadbed gradually raising；
D. subgrade and pavement has filled, timely construction subgrade guardrail, after earth-rock mixture object tends towards stability, according to embankment side slope
Slope is than construction Soil Slope；
E. after Soil Slope stabilization, contour cultivation slope surface trees.
Compared with prior art, the present invention with digging soil on the outside of existing roadbed by thickening roadbed filling to Slope than small
In 1:4.0 structure, while improving safety, it is possible to reduce subgrade protection project amount, while can reach reduction cinder field capacity
The purpose that expense is taken over the land for use and protected to reduce cinder field, has higher economic benefit.It is calculated by 10m filled-up ground height, unilateral side is filled out
Fang Bianpo can reduce dry-laid rubble 9m3/m.Reduce cinder field capacity 125m3/m.Due to having spread certain thickness soil in slope surface,
Trees are planted above, it is possible to reduce soil erosion, beautification highway environment reduce driver and conductor's fatigue, have higher environmental protection
Benefit.Simultaneously because grade of side slope becomes smaller significantly, and still there are trees to block outside conventional roadbed guardrail, traffic thing can be greatly reduced
Therefore the harm brought, there is higher economic and social benefit.
The configuration of the present invention is simple, easy for construction, securely and reliably, remarkable in economical benefits can be wide in filled-up ground technical field
General popularization and application.
