Description

The method increasing Stability of Soil of High Side Slopes
Technical field
The present invention relates to a kind of method increasing Stability of Soil of High Side Slopes, particularly one is applied to the realm of building construction Soil increase Stability of Soil of High Side Slopes method.
Background technology
Soil quality dam structure refers to the soil body thickness edge slope structure more than 25 meters, when soil body thickness is more than 25 meters, its Highly big, there is batholith in soil body bottom, under heavy rain, earthquake operating mode, slope instability easily occurs, and building and engineering cause weight When affecting greatly.In the prior art to the biggest soil-slope, in order to ensure its stable type, typically take to cut side slope slow (typically can delay in 1:2.5) or a large amount of excavation slope, the method increasing slope retaining measure.But it is of the prior art several In solution, unfavorable to construction investment, the duration is had an impact simultaneously, be also unfavorable for construction.Therefore prior art does not also have One can greatly reduce excavated volume, it is simple to construction, and safety is high, simple to operate, it is possible to effectively protects preventing soil quality dam from existing The method increasing Stability of Soil of High Side Slopes of slope instability is easily there is under heavy rain, earthquake operating mode.
Summary of the invention
The technical problem to be solved is to provide one can greatly reduce excavated volume, it is simple to construction, safety Height, simple to operate, it is possible to effectively to protect the increase soil property preventing soil quality dam from slope instability easily occurring under heavy rain, earthquake operating mode The method of Stability for High Slope.
For solving above-mentioned technical problem, the method increasing Stability of Soil of High Side Slopes that the present invention uses, including following step Rapid:
A, the soil body is cut slope process, 3.9 meters to 4.1 meters scopes bottom side slope, excavate into 1:0.749 to 1 temporarily: The abrupt slope of 0.51, and set up porous draining steel pipe in this range, steel pipe Nei Neisai scupper hose;
B, in the range of 2 meters to 3 meters from toe, set up concrete guard wall, between concrete guard wall and slope body, first place steel Muscle gabion, then backfill in space with rock ballast, concrete guard wall height flushes with reinforced gabion.When concrete guard wall reaches age After, pour into neat slurry at gabion or rock ballast top, to orrhorrhea top so that it is form entirety.
Further, concrete guard wall basis dowel is connected with basement rock.
Further, at concrete guard wall, PVC drain pipe is buried underground.
Further, pouring into the ratio of mud of neat slurry at gabion or rock ballast top is 0.7:1.
Further, described concrete guard wall uses the concrete of label C15.
Further, at side slope, geotextiles is laid.
The invention has the beneficial effects as follows: the present invention side slope top is suitably cut slope process, set up concrete guard wall with And reinforced gabion, and backfill space with rock ballast, its excavated volume is few, easy construction, and safety is high, simple to operate, processes cost low, The drag at toe can be increased, dramatically increase the stability of soil-slope.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Parts, position and numbering in figure: side slope 1, gradual sloped portion 2, reinforced gabion 3, concrete guard wall 4, rock ballast backfill Layer 5, draining steel pipe 6, geotextiles 7, dowel 8, PVC drain pipe 9, abrupt slope part 10.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
For solving above-mentioned technical problem, the method increasing soil quality dam 1 stability that the present invention uses, including following step Rapid:
A, the soil body is cut slope process, bottom side slope 1,3.9 meters to 4.1 meters scopes, excavate into 1:0.749 extremely temporarily The abrupt slope of 1:0.51, and set up porous draining steel pipe 6 in this range, steel pipe Nei Neisai scupper hose;
B, in the range of 2 meters to 3 meters from toe, set up concrete guard wall 4, first place between concrete guard wall 4 and slope body Reinforced gabion 3, then backfill in space with rock ballast, form the rock ballast backfill layer 5 in figure, concrete guard wall 4 height and reinforced gabion 3 Flush.After concrete guard wall 4 reaches age, pour into neat slurry at gabion or rock ballast top, to orrhorrhea top so that it is Form entirety.The method increasing soil quality dam 1 stability using the application only suitably carries out part side slope and cuts slope process, shape Become gradual sloped portion 2 in Fig. 1, retain a part of abrupt slope part 10 and make slope ratio be maintained at the scope of 1:0.749 to 1:0.51, and entering Row is cut the place of slope process and is arranged porous draining steel pipe 6, steel pipe Nei Neisai scupper hose, can be greatly saved compared to existing technology Excavation workload, and get rid of the hydrops that heavy rain causes in time, improve side slope 1 stability.Coagulation is set up in toe certain limit Soil barricade 4, and backfill with reinforced gabion 3 and rock ballast so that it is side slope 1 is formed effectively protection.
Concrete guard wall 4 basis dowel 8 is connected with basement rock.Concrete guard wall 4 is connected by dowel 8 with batholith, Newly-increased structure can be made to form entirety with batholith, thus improve structural stability.
PVC drain pipe 9 is buried underground at concrete guard wall 4.PVC drain pipe 9 is set in concrete guard wall 4, can be timely Get rid of the rainwater assembled inside concrete guard wall 4.
Gabion or rock ballast for ensureing backfill can be effectively formed an entirety and pour into striaght cement at gabion or rock ballast top The ratio of mud of slurry is 0.7:1.
For ensureing concrete guard wall 4 mass, described concrete guard wall 4 uses the concrete of label C15.
At side slope, lay geotextiles 7 can play waterproof effect.
Side slope 1 top is suitably cut slope and is processed by the present invention, sets up concrete guard wall 4 and reinforced gabion 3, and uses stone Slag backfill space, its excavated volume is few, easy construction, and safety is high, simple to operate, processes cost low, it is possible to increase resisting at toe Power, significantly increases the stability of soil-slope 1.
