Description
Technical field
The present invention relates to a kind of rivers, indoor simulation device and the test of library bank ecological safeguard structure stabilization and working property
Method field, in particular to river library bank slope ecological safeguard structure working performance simulator and method.
Background technique
River, library bank ecological safeguard structure be related to the stabilization of river library bank slope and the ecological problem in river, reservoir.So
And at this stage largely using materials such as the chain brick of open-cell concrete, steel wire (TGXG) gabion gauze pad, eco-concretes
River library bank slope protection technology is considered as " ecological vestige " although meeting the requirement of protection.But actually their ecology
Effect is poor.From the ecological of material, the artificial materials such as concrete, earth working material in use there may be
Some pairs of water quality of river have the substance of pollution, and material itself is not ecological enough；From price and safety, these materials
Price is generally higher, intensity easily decays at any time, the reasons such as aging and corrosion occur, these technologies there is also project cost compared with
Disadvantage high, long-term safety performance is poor；From using energy source, produces these artificial materials and usually require to consume more energy
Source, or even more serious ground contamination environment, do not meet the theory of sustainable development.
With the enhancing of Public environmental attitude, river is improved, the ecological of bank slopes maintenance technology is increasingly becoming mainstream.How
The natural materials such as plant, natural block stone are applied to actual river, is increasingly becoming in bank slopes maintenance engineering and is engaged in shore protection neck
Scholar the problem of extremely paying close attention to of domain research, because these natural materials are inherently ecological first, the compatibility with environment
It is good, good ecological effect, which is generated, for slope protection works has established important basis；Secondly, extensive, engineering is made with material source

Firmly, the strong rock of weatherability can not consider the factor of building stones strength retrogression in the engineering services time limit, moreover,
Plant haulm, which grows thicker and plant division effect, further enhance plant can to the restriction effect that block stone is displaced, and cause slope surface anti-
The general safety stability of watch box system increases.
Optimal protection effect can be played for how the materials such as the natural block stone of research, plant combine, is generallyd use
It is field test method, field test generally has the shortcomings that the test period is long, test input is high, and by natural environment
The influence of the external force such as wind load, freeze thawing is big, it is difficult to obtain live data.In order to overcome the shortcomings of that field test method, the present invention mention

Embodiment 3:
The present embodiment discloses a kind of experimental method based on 1 described device of embodiment, which is characterized in that including following step
It is rapid:
1) assembled device is plugged the plant stake physical model for needing quantity in plant stake physical model fixing pipe, plants
The selection of object stake physical model need to have certain rigidity, can bear the sliding force of bulk solid physical model, and do not deform, such as
Select galvanized wire.Moving trolley is driven by adjusting lead screw, so that shot block stone physical model installing system is horizontal.By shot
The uniform spreading of block stone physical model is into the rectangle frame of shot block stone physical model installing system.It is worth noting that can not touch
