Abstract
The present invention provides a kind of Seasonal freezing areas Freeway draining means of defence, along roadbed length direction, in the side slope of both sides, at spacing intervals, builds a main sewer along slope aspect, and the main sewer is connected to the french drain bottom of trench of bottom of slope；Between two main sewers, several points are selected along the direction parallel with main sewer, two branch sewers are built from each point, two branch sewers are downward-sloping, and be connected with the main sewer of both sides respectively；Dry-laid rubble is filled in main sewer and branch sewer, surrounding is wrapped up with infiltration geotextiles, and top surface is covered with fill stratum.
Description
Technical field
The present invention relates to highway construction technical field, and in particular to a kind of Seasonal freezing areas Freeway row
Water means of defence.
Background technology
High and cold seasonal freezing region, the spring melts the prosperity of phase massif intermediary water, and expressway slope is domatic to have seepage point, holds
It is also easy to produce large area slump.In order to ensure slope stability, it is necessary to carry out draining protection to cutting during highway construction.
The content of the invention
It is an object of the invention to provide a kind of Seasonal freezing areas Freeway draining means of defence, prevent season from freezing
, there is landslide phenomenon in area's slope instability.
Technical scheme is as follows：
A kind of Seasonal freezing areas Freeway draining means of defence, it is characterised in that：Along roadbed length direction,
In the side slope of both sides, at spacing intervals, a main sewer along slope aspect is built, the main sewer is connected to the french drain bottom of trench of bottom of slope；
Between two main sewers, several points are selected along the direction parallel with main sewer, two branch sewers, two are built from each point
Branch sewer is downward-sloping, and is connected with the main sewer of both sides respectively；Dry-laid rubble, surrounding are filled in main sewer and branch sewer
Wrapped up with infiltration geotextiles, top surface is covered with fill stratum.
The Supporting sewer construction that the present invention is used is convenient, and waterproof effect substantially, in seasonal frost region freeze thawing area, can be prevented effectively
There is slump phenomenon in slope instability.Supporting sewer intercepts slope runoff by ribbed skeleton, and it is directly imported gutter, weakens ground
Table runoff washes away to domatic, reduces surface water and is penetrated into in slopes；The branch sewer of embedment slopes can be intercepted effectively, drainage side slope
Interlayer infiltration in the soil body, main sewer is converged at by water, is arranged in roadbed gutter by main sewer.Supporting sewer is main by block slabstone
Constitute, masonry forms frame structure in total, slopes are divided into some fritters, and each skeleton is respectively subjected to certain limit
Interior soil body gravity, increasing stability prevents unstability from slump phenomenon occurring.
The Supporting sewer surface that the present invention is used is banketed covering, weakens artificial trace, reaches landscape effect.
Brief description of the drawings
Fig. 1 is main sewer of the invention and branch sewer floor map；
Fig. 2 is the cross-sectional view of main sewer；
Fig. 3 is the cross-sectional view of branch sewer；
Fig. 4 is the Longitudinal cross section schematic of main sewer.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, along roadbed length direction, in the side slope of both sides, at spacing intervals, one is built
Bar along slope aspect main sewer 1, the main sewer 1 is connected to the bottom of trench of french drain 2 of bottom of slope；Between two main sewers 1, along and main sewer
The selected several points in parallel direction, two branch sewers 3 are built from each point, and two branch sewers 3 are downward-sloping, and respectively with
The main sewer 1 of both sides is connected；Dry-laid rubble 4 is filled in main sewer 1 and branch sewer 3, surrounding infiltration geotextiles 5 are wrapped up, pushed up
Face fill stratum 6 is covered.
It is in a certain angle between main sewer 1 and branch sewer 2；During present invention specific implementation, the folder between branch sewer and main sewer
Angle is preferably 135 °.
Main sewer 1 and branch sewer 3 collectively form Supporting sewer, and Supporting sewer intercepts slope runoff by ribbed skeleton, will
It directly imports gutter, weakens rainwash and domatic is washed away, and reduces surface water and is penetrated into in slopes；The branch for imbedding slopes is oozed
Ditch can be intercepted effectively, the interlayer infiltration in drainage slope soil, and water is converged at into main sewer, be arranged in roadbed side by main sewer
Ditch.Supporting sewer is mainly made up of block slabstone, and masonry forms frame structure in total, slopes is divided into some small
Block, each skeleton is respectively subjected to a range of soil body gravity, and increasing stability prevents unstability from slump phenomenon occurring.
As shown in figure 4, during present invention specific implementation, main sewer defers to side slope ratio of slope in itself when building, and along length of grade
Direction sets the anti-skidding platform of two-stage.In the anti-skidding platform of two-stage, first order platform 7 is located at bottom of slope, and width 4m, second level platform 8 is located at
In slope, width 2m.
As a kind of specific embodiment of the invention, the spacing 3m between two adjacent main sewers of left and right；Neighbouring branch
The spacing of sewer is 3m.The deep 1m of main sewer, 0.8m wide；Branch sewer depth 0.6m, 0.4m wide；Banketing on main sewer and branch sewer
Overburden cover 0.15m.
