Abstract

The utility model discloses a blind drainage arched girder used for reinforcing a side slope, which comprises an arch waterspout and a macadam blind drain arranged in a sloping surface. The blind drain is connected with a slope base drainage trench; rainwater on the sloping surface and a slope body can be collected to the blind drain to realize quick drainage, thereby shortening the sluggish flow time of the rainwater on the sloping surface, preventing rainwater from collecting on the area of the sloping surface, and leading the arched girder and blind drain protection to serve the drainage function fully. Especially, the anti-sliding effect and the drainage effect of the blind drainage arched girder are better when being used on high-steep side slopes in a pluvial region.

Description

The blind drainage arched girder that is used for reinforcing side slope
Technical field
The present invention relates to a kind of means of defence of soil mass consolidation side slope, belong to the geotechnical engineering field.
Background technology
In the majority with engineering bank protection form in side slope protection method early, as clay Bao Po, hexagon hollow piece bank protection, mortar rubble masonry pavement, retaining structure protection etc.These schemes can play the effect of reinforcing side slope to a certain extent, but speedway is more and more filled out to height and is deep-cut direction and develop, natural environment is subjected to heavy damage around the highway, engineering protection no doubt can satisfy the highway safety designing requirement, for side slope provides a retaining reinforcement measure, make it to accomplish that deep layer and shallow-layer are stable, yet its weak point is to lack ecological effect.Though yet can plant green vegetation as rhombus framework bank protection etc., on the one hand because rain drop erosion, the extension of vegetation root system makes the soil body produce the crack, and the growth in the big space of the soil body forms the hole, causes upper side slope stability to have hidden danger; On the other hand, sloping top ponding can not in time be discharged, and alluvial draining or rainwater wash away domatic large tracts of land, make upper side slope stability be subjected to very big threat.
Current most important be exactly to strengthen side slope waterproof and draining, in order to avoid, cause side slope slump accident because of the problem of water.We have tested a kind of method of reinforcing side slope in the open air---the blind drainage arched girder, both play the effect of engineering bank protection, improved original natural landscape again, especially can solve the slope drainage problem well, design, simple, the easy row of construction, the slope reinforcement effect is remarkable.
Summary of the invention
But the objective of the invention is a kind of reinforcing side slope and blind drainage arched girder than the forced-ventilated water function is arranged, this arched girder is reinforcing side slope effectively, stablizes geotechnical body, and the plantation vegetation can greening environment in the arched girder.Especially the domatic following french drain that is provided with can compile rainwater in domatic and the sloping body, and effectively eliminating, and the backwater that reduces to deposit is to the washing away of side slope, and drain function is powerful, helps stability of slope, is a kind of method for reinforcing side slope efficiently.
The object of the present invention is achieved like this: a kind of blind drainage arched girder that is used for reinforcing side slope, as shown in Figure 1, agent structure is made up of the concrete arch beam, is used for reinforcing side slope, prevents the side slope slump, by the semicircular arch rhone, domatic rainwater is got rid of smoothly.The plantation vegetation is slowed down rain drop erosion and anchoring topsoil in the beam, in the middle of two arch beams french drain is set, and is used to compile domatic and sloping body rainwater and eliminating.
Fig. 1 is the front view of blind drainage arched girder, is used for side slope protection.
Fig. 2 is the sectional drawing of 1-1, is the arched girder rhone, is used for slope drainage.
Fig. 3 is the sectional drawing of 2-2, is french drain and spill rhone, is used to stablize sloping body and slope drainage.
Fig. 4 is the sectional drawing of 3-3, is domatic french drain down, is used for top, slope, the concentrated charge for remittance of domatic, sloping body and draining.
Backfill planting soil in the arched girder can be planted the vegetation of suitable local climate.
The present invention is applicable to various soil-slopes.
Advantage of the present invention is: one, reinforce function efficiently: based on engineering protection, arch beam is an open system, allows the soil body that certain breathing and stress release are arranged, and can play the purpose of integral protection, is easy to stability of slope; Two, greening environment: with vegetative protection is auxilliary, and plantation vegetation in the beam, but both greening environments can be tackled rainwater again, be slowed down runoff and consolidated soil; Three, drain function is powerful: establish french drain in domatic, can compile rainwater and effectively eliminating fast, shorten the viscous flow time of rainwater in domatic and sloping body, avoid rainwater to compile in domatic zone, the high gradient slope that is particularly useful for the area of heavy rainfull, its antiskid, drainage effect are better.
The blind drainage arched girder has powerful drain function, the design philosophy that adopts vegetative protection to combine with engineering protection, brought into play the advantage separately of the two, efficiently solve the contradiction of slope project protection and environmental destruction, both guaranteed the stable of side slope, realize the fast quick-recovery of slope vegetation again, reached the harmonious coexistence of mankind's activity and natural environment.

The specific embodiment
One, construction lofting, brush slope are to design attitude, and all loosen the soil on the removing side slope;
Two, excavation french drain, bottom is built by laying bricks or stones with slabstone, lays rubble above, and top layer is built by laying bricks or stones with slabstone;
Three, gutter, the end, excavation slope makes the french drain infiltration get rid of smoothly by the gutter;
Four, excavation arched girder groove, concreting is provided with the arch form rhone, domatic reservation deformation joint;
Five, landfill planting soil in the arch, the hydraulic pressure grass-seed of sowing grass seeds by duster, the watering back covers nonwoven, guarantees that vegetation survives.

Claims (1)

1, the blind drainage arched girder that is used for reinforcing side slope is characterized in that slope protection is circular-arc arched girder design, and is domatic by the concreting arch beam, lay rhone between beam by slabstone, the rubble french drain is set in domatic, and the shop is to the end, slope, and the rubble french drain is communicated with gutter, the end, slope.
