Description
Technical field
The invention belongs to highway engineering construction technical fields, and in particular to a kind of building the road based on biological enzyme soil-solidified-agent
Method.
Background technology
It is extremely wide that road construction work is related to face, almost covers farming, forestry, animal husbandry, sideline production and fishery all trades and professions.In some municipal works（Landscape
See engineering, Municipal Road Engineering etc.）, production and operation produce institute（Mining, plantation etc.）Etc. generally requiring to build all types of roads
Road, such as interim heavy-load road, permanent heavy-load road, fast simple channel, simple garden road, this kind of road is to building speed, work
Cheng Chengben, bearing capacity, ecological, environmental protective etc. it is more demanding, and traditional road building technology has that build the period long, of high cost
The shortcomings such as high, larger to periphery eco-environmental impact.The base of national standard highway is built, traditional road building technology is repaiied
The roadbase built（Such as steady layer of water, grey soil layer, two grieshoch, graded broken stone layer）It needs to expend a large amount of manpower and materials, it also can be right
Ecological environment adversely affects.
Invention content
Present invention seek to address that the above problem, provides a kind of method of constructing roadway based on biological enzyme soil-solidified-agent, it can be fast
Speed construction reduces cost and artificial, while Environmental Safety.
According to the technique and scheme of the present invention, the method for constructing roadway based on biological enzyme soil-solidified-agent, including nonstandard road
Or the build of road base layer and two steps of build of road layer,
The nonstandard road or road base layer build include the following steps：
A1, it loosens the soil：Soil 25-35cm depth is excavated, sand is added or clayed soil is adjusted to grain size in soil and is less than 75 μm
Clay is no less than 20%；
A2, sprinkling biological enzyme soil solidification agent solution：It is good to pine uniformly to spray deployed biological enzyme soil solidification agent solution
Soil layer surface is calculated by volume after compacting, and 28-32m can be built with the solution that every liter of biological enzyme soil-solidified-agent is allocated3Road
Subject to；
A3, it is stirred：The soil for spraying biological enzyme soil solidification agent solution is stirred, is sufficiently mixed；
A4, road sizing, pavement compaction；
A5, cover：Deployed biological enzyme soil stabilization agent solution is uniformly sprayed again in the road crust of A4 compactings, into walking along the street
Face closure waterproof；
A6, it is compacted again：Road Compaction is carried out again forms nonstandard road or road base layer；
The build of the road layer includes the following steps：
B1, it is laid with the aggregate grading material of 6-7cm thickness on the surface of the A6 road base layers for being compacted to be formed again；
B2, aggregate grading material and base are fully mixed and stirred, road base layer is 4-5cm by the depth of scarifying, and it is 11- to mix and stir depth
13cm；
After B3, road sizing, the amount of 10% biological enzyme soil solidification agent solution 4L is sprayed according to every square metre of road, is uniformly sprayed
It spills；
B4, compacting road surface, face layer uniformly spray biological enzyme soil solidification agent solution again, carry out face layer closing；
B5, finally it is compacted road.
Further, in the A4 steps, the dry density after pavement compaction is 1.52-1.55g/cm3。
Further, in A5 the and B4 steps, the biological enzyme soil stabilizer application amount of sprinkling is 1L/1000m2, raw
Amount of water in object enzyme soil stabilization agent solution is subject to and can uniformly be sprayed.
Further, in the B1 steps, aggregate grading material is by the wetland sandstone of 4-4.5cm and the goose of 2-2.5cm
Cobble batch mixing forms, wherein the grain size of cobblestone is 1-3cm.
The beneficial effects of the present invention are：It is short, at low cost, small to periphery eco-environmental impact to build the period；It is steady without water
The build of layer, grey soil layer, two grieshoch, graded broken stone layer etc., construction is simple greatly reduce manpower and cost；Using biological enzyme
Soil-solidified-agent stablizes the soil with various physics and chemical characteristic, increases the intensity and stability of soil, prolongs
The service life of long road；Pitch, cement in alternative traditional handicraft, more Environmental Safety.
Specific implementation mode
The present invention is further explained in the light of specific embodiments.
The present invention is the method for constructing roadway based on biological enzyme soil-solidified-agent, including road base layer is built and road layer is built
Two steps.
Wherein, nonstandard road（Such as interim heavy-load road, fast simple road, landscape garden road）Or road base layer builds packet
Include following steps：
A1, it loosens the soil：Soil 25-35cm depth is excavated to be properly added sand depending on edaphic condition or clayed soil is adjusted in soil
Clay of the grain size less than 75 μm is no less than 20%, is conveniently adapted to biological enzyme soil-solidified-agent；
A2, sprinkling biological enzyme soil solidification agent solution：It is good to pine uniformly to spray deployed biological enzyme soil solidification agent solution
Soil layer surface is calculated by volume after compacting, and 28-32m can be built with the solution that every liter of biological enzyme soil-solidified-agent is allocated3Road
Subject to, the amount of water in solution regards edaphic condition, and being subject to normally to be stirred；
