Description

A kind of gutter and french drain integration drainage system
Technical field
This utility model belongs to highway drainage field of engineering technology, it particularly relates to a kind of gutter and french drain Integration drainage system.
Background technology
Water damages, damaged or destroyed by flood occupies the biggest proportion in highway subgrade disease, increasingly payes attention to highway drainage in Road Design System perfect.Such as, Chinese patent (CN 201220119214) discloses a kind of highway pavement and dredges weeper drain, bag Including and dig out longitudinal strip ditch in runway and footpath junction along road direction, pad laid the most successively by this longitudinal strip ditch Layer, stone layer, middle husky loaded filter, the steady layer of water, coarse grain formula bitumen concrete layer, particulate formula bitumen concrete layer are to concordant with road surface;Have and stone Lateral drainage passage that sublayer communicates or lead to passage above.This utility model uses in highway pavement mending course, Current can be guided to flow out road surface by the french drain technology of dredging, it is ensured that highway pavement intensity, effect a radical cure surface gathered water crux, resistance Sealing stream damages road surface, solves the technical barrier in pavement patching, it is to avoid situation bad after repairing before road surface occurs, and ensures road Road unimpeded, decreases maintenance cost.But highway french drain mostly is simple infiltration rubble column structure at present, uses masonry method to execute Work, its major defect or deficiency be mainly manifested in: existing blind ditch construction difficult quality controls;Execavated rockmass soil internal water is the most saturating Cross french drain metalling to enter inside roadbed.
Summary of the invention
For solving above-mentioned technical problem, this utility model provides a kind of gutter and french drain integration drainage system, On the basis of simple and practical, execavated rockmass soil internal water can be stoped to enter roadbed, get rid of execavated rockmass soil to a greater extent Internal water, it is to avoid subsurface flow washes away roadbed and forms cavity.
A kind of gutter described in the utility model and french drain integration drainage system, described drainage system includes gutter Main body 1, french drain main body 2, anti-seepage geotextile 3, PVC soakaway trench 4 with holes, metalling 5 and infiltration geotextiles 6;Described gutter main body 1 The gutter projection 8 of bottom matches with the french drain groove 7 at french drain main body 2 top, is assembled into integral type drainage system;Described antiseepage Geotextiles 3 is located at bottom french drain and side;Described PVC soakaway trench 4 with holes longitudinally spreads above the anti-seepage geotextile 3 bottom french drain If;Described metalling 5 backfills inside french drain;Described infiltration geotextiles 6 is laid on outside metalling.
A kind of gutter described in the utility model and french drain integration drainage system, described gutter main body 1 is prominent in band The concave shape risen, french drain main body 2 is in groove up-narrow and down-wide I-shaped.
A kind of gutter described in the utility model and french drain integration drainage system, described gutter main body 1 and french drain Main body 2 is made up of cement concrete material.
A kind of gutter described in the utility model and french drain integration drainage system, for introversion 8-bottom described french drain The inclined-plane of 12%.
A kind of gutter described in the utility model and french drain integration drainage system, described gutter main body 1 and french drain Main body 2 is prefabricated section and is formed by connecting, and each prefabricated segment length is 2.0m-2.5m.
Compared with prior art, gutter described in the utility model and french drain integration drainage system have the most excellent Point: french drain is along roadbed laterally for closing water-stop structure, and in preventing side slope, moisture penetrates into inside roadbed;Use precast construction, gutter Bottom is prominent to be placed in french drain groove so that gutter is connected firmly with french drain;Use precast construction, it is easy to mass processing, and And compare tradition french drain and gutter, construction quality is easily guaranteed that, and is easily installed, the reduction of erection time.
