Abstract
The invention discloses a cable-stayed anchor rod reinforced mixed double-substrate drain groove. The drain groove comprises anchor rods, a substrate water guide groove, a soil base bottom surface, a rigid substrate and a water permeating hole. All anchor rods are arranged on a roadbed slope of the substrate water guide groove, and are parallel to each other; and cement mortar layers are sprayed on the roadbed slope of the substrate water guide groove, the groove bottom and the surface of a highway slope. The rigid substrate is arranged between the bottom of the substrate water guide groove and the soil base bottom surface; and the water permeating hole is formed in one side of the roadbed slope near the substrate water guide groove. The substrate drain groove exerts functions to the greatest extent by using anchoring of inclined anchor rods and double-layer protection of the cement mortar layers and the rigid substrate, and reduces the influence of water permeation and unstable roadbed on the substrate drain groove; and meanwhile, the structure is simple in construction and excellent in practicability.
Description
Technical field
The present invention is the mixing double-basis layer drainage groove of a kind of oblique pull bolt anchorage, belongs to Highway Slope bank protection technical field of drainage.
Background technology
In the work progress of the infrastructure such as highway, railway, water conservancy, mine, the destruction of original place looks vegetation is inevitable, spoir, abandons stone, excavation etc. and can leave substantial amounts of bare side sloping to harmonious natural environment.These side slopes have plenty of rock side slope, have plenty of soil-slope, steep or flat.According to recovering ecological principle, under conditions of getting rid of environmental disturbances, soil-slope has the ability of self-regeneration, recovery, but this is a very long process, along with the change of environment has a lot of uncertainty, it is impossible to reach protection and the effect of greening in time.The condition of rock side slope for want of vegetation growth, it more difficult in self-recovery.In consideration of it, only by manually accelerating its recovery process.Utilize vegetation stable side slope, improving the ecological environment is referred to as protecting slope ecology on ecology.During the nearly last ten years, it has been developed that and multiple can play good side slope protection effect, again can betterment works environment, embody the Way for Slope Plant Protection new technique that natural environment is beautiful.The engineering protection measure that it is different from the past; slope project plant protection system can be collectively forming with traditional slope engineering safeguard procedures; by domatic steady in a long-term for the purpose of; with protection local Natural plant community structure, restored ecosystem, prevent erosion, alleviate management workload as objective, reach the purpose of reinforcing side slope mainly by being mutually wound around between the adhesive force between root system of plant and soil and root system.Protecting slope ecology can be with water conservation, minimizing soil erosion, it is also possible to effectively purifies air, protecting ecology, beautify the environment, has ecological benefits.
Effect and the form of slope protection are as follows:
1, slope protection includes plant protection and engineering protection, and construction must be in good time, stable, prevents water, temperature, eolian action from destroying the domatic of side slope.
2, plant protection typically uses and litters, plant grass and plant shrub (trees) form, should select be prone to survive, be easy to the plant kind of maintenance and economy according to factors such as local climate, soil property, water content.
3, turfing protection: be applicable to various soil-slope.Preferably selecting banding or block turf, specification is neglected greatly condition of construction and is determined, sod thickness is directly 10CM.During laying, should be followed closely to upper berth by toe, be fixed on soil-slope with point wood (or bamboo) stake.The forms such as tiling, lay-up or checkering paving can be selected as the case may be.When domatic be provided with dirty work skeleton turfing within it time, skeleton should embed domatic, and surface should be connected with turf.
4, grass protection is planted: be applicable to the slight embankment of stability of slope, slope wash and cut slope.Grass seed should be spread in uniform in the soil property cleared up domatic on, carry out protective measure simultaneously.To the soil property being unfavorable for that grass class grows, should be at domatic first a layer 10～the planting soil of 15CM of paving.Cut slope steeper or higher time, can by test use grass seed mix with the organic mud containing fertilizer, spray in domatic.
5, shrub (trees) protection: be applicable to soil side slope.Method for planting is by design requirement construction, but it should be noted that plants season.Highway, Class I highway side slope on, forbid plant arbor.
6, engineering protection is applicable to be unsuitable for the sty of vegetative growth.General employing is wiped one's face, beats face, is whitewashed, hooks the forms such as (filling) seam, domatic revetment.Before construction, should domatic impurity, surface dust, loosening stone and top layer air slaking and fragmented rock body be removed clean；When there being diving to expose, diversion or process of damming should be made.
Summary of the invention
It is an object of the invention to solve saturated yielding that existing Highway Slope produces when running into soft soil roadbed, subside, the disease such as local instability, to stablizing during realizing construction of the highway, using, promote use quality and the service life of highway.
For achieving the above object, the technical solution used in the present invention is the mixing double-basis layer drainage groove of oblique pull bolt anchorage, and this drainage groove includes anchor pole (1), basic unit's guiding gutter (2), soil matrix bottom surface (3), rigid base (4), water seepage hole (5).
Specifically, the roadbed slope of basic unit's guiding gutter (2) is provided with each anchor pole (1), and each anchor pole (1) is parallel to each other；The roadbed slope of basic unit's guiding gutter (2), bottom land, Highway Slope surface are coated with cement sand bed.
It is provided with rigid base (4) between bottom and soil matrix bottom surface (3) of basic unit's guiding gutter (2)；Water seepage hole (5) is positioned close to the roadbed slope side of basic unit's guiding gutter (2), and water seepage hole (5) connects basic unit's guiding gutter (2) and soil matrix bottom surface (3).
Described anchor pole (1) oblique cutting enters the roadbed slope of basic unit's guiding gutter (2), and the angle of cut between anchor pole (1) and horizontal plane is 8 °-20 °.
The material of described rigid base (4) is cement concrete pellet or cement concrete rubble or cement stabilized soil or two ash concrete pellets or two ash concrete crushed stone or lime-sand-clay mixture, and the thickness of rigid base (4) is 50-100mm.
The roadbed slope toe of water seepage hole (5) distance basic unit's guiding gutter (2) is 1:2-1:3.5 with the ratio of the Highway Slope toe of water seepage hole (5) distance basic unit's guiding gutter (2).
Compared with prior art, the present invention has the advantages that.
1, this structure is provided with cement mortar protective course by, bottom of trench domatic at each of basic unit's guiding gutter, in order to stop outer flowing water to penetrate into roadbed, it is ensured that service life of roadbed and use quality.
2, the roadbed slope of basic unit's guiding gutter of this structure is provided with each anchor pole, and oblique being evenly arranged of anchor pole anchors at the roadbed slope of basic unit's guiding gutter；Effectively increase the roadbed slope stability of basic unit's guiding gutter.
3, the rigid base of this structure arranges position and thickness can effectively ensure that the stability under loading between the bottom of basic unit's guiding gutter and soil matrix bottom surface, prevents because of impact on basic unit's guiding gutter of infiltration or the saturated yielding of subgrade soils.
