Abstract

The invention provides an ecological recovery method with combination application of vegetation concrete and high-molecular aggregates, and is applied to fields of riverway slope protection engineering, ecological recovery engineering, garden greening engineering and the like. The ecological recovery method comprises the following steps: first, vegetation concrete is prepared; second, high-molecular aggregates are prepared; third, a riverway or a slope is cleaned to meet construction requirements, a layer of nutrition earthwork cloth is laid on a construction surface first, then the vegetation concrete and high-molecular aggregates are mixed and stirred for half hour completely, and then subjected to pouring on the earthwork cloth, and the pouring thickness is 10-15 cm; fourth, after the vegetation concrete is poured for 4h, watering curing is started, according to local climate change, the curing state with water every day is kept until plants sprout, and then curing is continued for half month to a month. The problems that plants cannot survive because of too high dosage of vegetation concrete cement and the anti-scouring property of vegetation concrete is not enough because of too low dosage of cement are solved.

Description

A kind of plant cover concrete be combined with polymer granule application ecological recovery method

Technical field

Be applied to the fields such as river course slope protection engineering, Ecological Restoration Works, landscape engineering.

Background technology

Plant cover concrete is to adopt specific concrete formulation and mixing to plant green seed, a kind of nascent state guard technology that rock slope is protected and afforested.Polymer granule is as a kind of artificial soil technology that is widely used in engineering practice, firm side slope, repaired exposed massif, and recover the original ecological balance is worked it out to contribution.

The matrix of plant cover concrete has certain mechanical strength after solidifying, and does not chap, and does not wash away, and does not run off.But in this technological method, added cement, if cement consumption is few, deficiency is so that matrix reaches enough intensity.If for construction intensity adds cement in a large number, grass can not have been survived again.In construction in the past, all to increase matrix fertilizer and reduce concrete alkalescence by the method for adding plant cover concrete green additive, so that plant cover concrete adapts to plant-growth more, but whether carry out in this way excessive reduction cement alkalescence, otherwise concrete mechanical strength does not reach requirement, also can produce crack performance, in the situation that both sides reach balance, plant variety that can Adaptable growth is limited.So want that in the situation that cement adding is appropriate solving matrix is not washed the difficult problem not running off, we have selected polymer granule, after its distinctive honeycomb structure and injection, can be adsorbed in rapidly the characteristic on massif surface, can both supply the shortcoming of plant cover concrete, and for plant-growth provides the sufficient nutrient of sending out, the slightly acidic of polymer own, has certain neutralization to the weakly alkaline of plant cover concrete, and more plant can be planted in this new ecological recovery method.

Summary of the invention

The invention provides a kind of plant cover concrete be combined with polymer granule application ecological recovery method, be applied to the fields such as river course slope protection engineering, Ecological Restoration Works, landscape engineering, it is characterized in that: comprise the following steps:

1., prepare plant cover concrete, by sandy loam 10 ~ 12 weight parts, cement 2 ~ 3 weight parts, Pericarppium arachidis hypogaeae 1 ~ 2 weight part, green additive 1 ~ 2 weight part, plant seed (by Bamboo resource and the planting density requirement interpolation of weighing), mixing water 12 ~ 15 weight parts stir;

2., prepare polymer granule, by silicon breeze 10 ~ 12 weight parts, rice husk 2 ~ 3 weight parts, chicken manure 1 ~ 2 weight part, turfy soil 2 ~ 3 weight parts, scrap steel 1 ~ 2 weight part, water-holding agent 1 ~ 2 weight part, stablizer 1 ~ 2 weight part, agent 1 ~ 2 weight part, mixing water 15 ~ 20 weight parts stir;

3., level river course or the domatic construction requirement that reaches, in construction surface, first lay one deck nutrition geotextile, then by described plant cover concrete and the abundant mix and blend of polymer granule after-pouring half an hour in geotextile, building thickness is 10 ~ 15cm;

4., plant cover concrete builds after 4 hours, starts water seasoning, according to local climate, changes, and keeps having every day the state of water curing until after plant germination, adheres to continuing maintenance two weeks to month, specifically looks plant-growth situation fixed.

As preferably, the sandy loam of described plant cover concrete is the ground surface soil after air-dry pulverizing and sieving, and sand grain content is no more than 5%, and maximum particle diameter is less than 8mm, and water content is no more than 20%; Described cement is 52.5 grades of silicate cements of P II.

As preferably, the silicon breeze of described polymer granule is 40 ~ 60 orders, it is Harbin that described turfy soil is selected the place of production, organic content 70%-80%, humic acid 40%-50%, pH value is 5.0-5.5, described scrap steel is the waste and old steel that the longest edge footpath of pulverizing is no more than 2 ~ 3cm, described water-holding agent is sodium polyacrylate High hydrophilous resin, and described stablizer is Vinyl Acetate Copolymer, and described agent is the agent of polypropylene-base granule.

As preferably, described green additive is CBS plant cover concrete green additive, and described plant seed will have necessarily alkali-proof, and selects according to construction ground and local climate.

By the enforcement of above method, 1, solved the too high plant of plant cover concrete cement consumption and cannot survive, the inadequate difficult problem of the too low plant cover concrete self of cement consumption scour resistance;

2, solved and in growing process, lacked enough nutrition and the technical barrier of moisture content.
