Description
Technical field
Particularly a kind of the invention belongs to road engineering technical field, runoff pollution treatment effect is good, and ecological close friend
For environmental combination bank protection and the construction method of the punishment of road runoff pollution.
Background technology
While road and the various vehicles bring enormous benefits for human society, they are to natural landscape and ecology
The various negative effects such as segmentation, interference, destruction and the pollution of system are also constantly being deepened and are being expanded.At present, environmental road is built
The theory on road is more ripe, and permeable pavement is the important step in its construction.Restoring vegetation concrete have regulate and store, it is biological suitable raw,
Various functions such as noise reduction, there is certain filtration, purification ability, but flourishing with transportation, road runoff to sewage
In pollutant kind it is more complicated, pollutional load is further serious, and common restoring vegetation concrete can not meet present road footpath
The requirement of stream pollution punishment.
At present, road slope protection form is mostly completely spread or simple grass planting protection using hardening.Protection side slope hardening
Degree is too high so that landscape effect is poor.And simple grass planting protective slope acts on smaller, rain drop erosion easily causes side slope soil loss.
In a word, the problem of prior art presence is：Road slope protection runoff pollution punishment effect is poor.
The content of the invention
It is an object of the invention to provide a kind of environmental combination bank protection for the punishment of road runoff pollution, runoff pollution
Regulation effect is good, and ecological friendly.
Another object of the present invention is to provide a kind of applying for environmental combination bank protection for the punishment of road runoff pollution
Work method.
The technical solution for realizing the object of the invention is：
A kind of environmental combination bank protection for the punishment of road runoff pollution, including primary protection slope, banket and two grades
Protective slope, the primary protection slope is assembled into sash and completely spreads using prefabricated regeneration concrete bar, each prefabricated regeneration concrete bar
The reserved octagon duct in longitudinal direction, cast-in-place vegetation type diatomite regeneration concrete in sash；The banket uses vegetation type again
Growing concrete completely spreads protection；Two grades of protective slopes completely spread protection using prefabricated hexagon regeneration concrete block.
The technical solution for realizing another object of the present invention is：
A kind of construction method of environmental combination bank protection for the punishment of road runoff pollution, comprises the following steps：
(10) domatic finishing：According to design slope than surveying setting-out, carry out cutting slope and finishing is domatic, by design altitude, width
And depth, hand excavation bears down on one, pin groove, sash groove；
(20) sash assembling：After domatic finishing acceptance(check), prefabricated regeneration concrete bar is assembled into sash；
(30) spread concrete：The even vegetation type diatomite regeneration concrete that paves in rhombus sash；
(40) vegetation plantation：Soil is spread on the vegetation type diatomite regeneration concrete of hardening consolidation, grass seeds is broadcasted sowing, earthing,
Maintenance；
(50) banket is completely spread concrete：Vegetation type regeneration concrete is completely spread in banket；
(60) two grades of protective slopes are spread concrete block：Hexagon regeneration concrete block is completely spread in two grades of protective slopes.
Compared with prior art, its remarkable advantage is the present invention：
(1) using vegetation type diatomite regeneration concrete as side slope protection form, concrete regenerating is used in engineering
Aggregate, had both saved the processing cost of a large amount of building castoffs, and the consumption of natural resources is reduced again, and economic and environmental benefit is bright
It is aobvious；
(2) will be combined with recycled concrete mixed with diatomaceous restoring vegetation concrete, can not only reach side slope
The purpose of protection, while enhancing treatment effect of the side slope material to road runoff pollution.Result of the test shows, vegetation type diatom
Native regeneration concrete has different degrees of raising to the clearance of every pollutant compared with common porous concrete, particularly to ammonia nitrogen
And the clean-up effect of heavy metal is substantially, meets the demand for development of Eco-friendly road.
The present invention is described in further detail with reference to the accompanying drawings and detailed description.

(30) the spread concrete step includes：
(31) concrete-agitating：By the proportioning of cast-in-place vegetation type diatomite regeneration concrete, regeneration aggregate, water are put into successively
Mud, diatomite, after stir about makes its preliminary mixing for 30 seconds, then divide 2- by the water of ormal weight and concrete for plant growth additive mixed liquor
3 additions, continue stir about 1.5-2 minutes；
Diatomite porous regeneration concrete mixture reclaimed water mud fluidity is small and consumption is few, to ensure cement mortar equably
Package aggregate, using forced mixer, mixer is put into during stirring in the regulation ratio and feeding sequence of material by material, first
Cementitious matter, rubble stir about are made into its preliminary mixing for 30 seconds, then the moisture of ormal weight is added into continuation stir about 1.5-2 for 2-3 times
Minute.Depending on the degree of stirring, can the proper extension churned mechanically time, it is but unsuitable long.
(32) concrete speading：Transport vegetation type diatomite regenerated concrete mixture time control within 10 minutes,
Roadbed is moistened with water before pouring, diatomite regenerated concrete mixture is paved in rhombus sash even, it is smooth using flat board
And pat closely knit, cast is continuously sprinkled water after 1 day and is conserved one week.
Diatomite porous regeneration concrete belongs to dryness concrete material, and initial set is fast, and according to weather conditions, haulage time is typically controlled
Within 10 minutes, haulage time is 5 minutes to system during heat, to ensure the moisture in celluar concrete material.
Before pouring, roadbed first is moistened with water, between the otherwise diatomite porous quick dehydration of regeneration concrete will weaken aggregate
Adhesion strength.Diatomite porous regenerated concrete mixture is paved in rhombus sash even, typically adopted in casting process
It is smooth with flat board and pat closely knit, should not strongly vibrate or tamp.Cast starts watering maintenance after 1 day, pressure should not be used during water drenching
Power water column flings concrete surface, preferably directly waters from the top down under normal conditions, and curing time is no less than 7 days.
