Specific embodiment
The present invention will be described in detail With reference to embodiment.
The present invention relates to a kind of Debris Flow on Slope Surface control structures, and the shilong dam 1 of multiple tracks transverse direction is arranged from top to bottom in slope surface,
Arch form skeleton 6 is set between shilong dam 1, and array opens up skeleton hole window 3, the arch form bone of 3 outer rim of skeleton hole window on arch form skeleton 6
It is provided with the edge 7 that intercepts water of protrusion on frame 6, forms gutter channel 8 between the edge 7 that intercepts water between adjacent bone frame aperture window 3, gutter channel 8 is certainly
It is interconnected under above.
Shilong dam 1 is laterally closely assembled by gabion layering, and bottom gabion volume is greater than upper layer gabion volume, is formed and is expanded
Big 1 basis of shilong dam.Gabion includes rockfilling for gabion skeleton, steel mesh and inside, and gabion skeleton seamed edge is galvanizing steel, iron
Silk screen is galvanized wire mesh.It helps to prick connection by galvanized wire between adjacent gabion.
One of horizontal flap side 4 is provided with above upper layer shilong dam 1, lower section connects with arch form skeleton 6；Bottom shilong dam 1
Top is provided with one of horizontal flap side 4, connects with arch form skeleton 6, and lower section is provided with one of horizontal fringing 5.
Arch form skeleton 6 uses slabstone or concrete masonry, concrete cast-in-situ；The edge 7 that intercepts water is built using concrete precast block
It builds or concrete cast-in-situ.It is laid in skeleton hole window 3 and builds slabstone, concrete block, hollow brick or plantation sowing.
Water-blocking bank or clint 9 is arranged in 8 face of gutter channel.
The expansion joint 2 that arch form skeleton 6 is horizontally arranged at interval longitudinal, expansion joint 2 is through longitudinal gutter channel 8.
Pitch hemp cut is completely filled in stitching in expansion joint 2.
Work progress of the invention are as follows:
1, gabion is bound
Gabion specification has 2 kinds: I types (2m x 2m x 1m) and II type (2m x 1.5m x 0.5m).Gabion is by skeleton reinforcing steel bar
It is constituted with iron wire mesh sheet.Skeleton reinforcing steel bar uses 8 galvanizing steels.Wire netting is assembled by the mesh sheet that special-purpose machinery is woven into, double
Knot braiding, cellular mesh (having a size of 80 × 100mm), iron wire diameter are not less than 4mm.
2, shilong dam is constructed
(1) surveying and locating.From bottom to top by slope surface, one of shilong dam of every 30 meters or so arrangements, per pass shilong dam is substantially same
On contour, and spreads lime and mark position.
(2) for safety, from top to bottom by road construction shilong dam.
(3) foundation trench is excavated, smooth, compacting foundation fills leveling when necessary with cobble or rubble.
(4) building stones dress cage answer code to build, plug it is tight, two layers of gabion contact surface is answered smooth, prevents building stones corner angle from pounding the damage of suspension lattice
Gabion.Close to the stone of mesh outer layer application larger size, careful code is built and goes out the extension cornicult of stone other than mesh, plays guarantor
Protect the effect of gabion.
(5) it after the completion of building stones dress cage, should be connected firmly using Binding material between cage lid and cage body.The middle part of multilayer gabion
Bottom uncovered point can be used or have and cover bottomless gabion, it, should be every 20cm or so with tying up between cage lid and cage body and adjacent gabion
Material is pricked to be connected and fixed.
(6) it should be tied up, be connected integral using iron wire between each gabion.
3, skeleton is constructed
(1) slope surface surface dust is cleaned with water before constructing, and fills up pit, slope surface is substantially flat.
(2) frame position is laid by slope surface width.Skeleton or master, branch skeleton tie point are started setting up from shilong dam, successively
Arrangement upwards.
(3) hand excavation's skeleton groove, depth should meet skeleton buried depth requirement.
(4) it should be first constructed at skeleton node when skeleton is poured or built, then other positions of constructing, two skeleton nodes should be at
Sustained height.
(5) skeleton, which is poured or is built, to carry out from bottom to top, and should be closely connected with slope surface, and skeleton flowing water face should be smooth.
(6) skeleton channel bottom should ram clap it is closely knit, skeleton periphery gap is answered backfill and is rammed closely knit.
(7) water blocking edge should be poured or be built together with skeleton.
(8) after the completion of skeleton construction, protection works in sky window are come into effect.
It 4, is security consideration, shilong dam and skeleton should all construct from the road treatment range Shang Erxiazhu.
5, skeleton slope protection is destroyed to avoid shilong dam from digging base, can constructed therebetween after the completion of construction per adjacent 2 shilong dam
Skeleton slope protection and its correlation engineering.
The contents of the present invention are not limited to cited by embodiment, and those of ordinary skill in the art are by reading description of the invention
And to any equivalent transformation that technical solution of the present invention is taken, all are covered by the claims of the invention.
