Abstract
The anti-skidding method of three-dimensional slope protection is carried out using bamboo plant the present invention relates to a kind of, utilize bamboo plant well developed root system, fast growing, root system network can be quickly formed in soil horizon in a Growing season, while the tractive force of bamboo plant root system and torsion carry all bigger characteristic.The present invention consolidates that the anti-skidding effect in slope is obvious, and the tensile strength and shear strength of stero of the invention all obtain the promotion of several times and more than ten times.
Description
Technical field
The invention belongs to slope protection anti-slip technology field more particularly to a kind of using bamboo plant to carry out three-dimensional slope protection anti-skidding
Method.
Background technique
Traditional flood land consolidates slope non-skid feature, such as pneumatically placed concrete, mortar flag stone revetment, shotcrete slope protection, anchor and spray net shield
Slope etc., to mitigating, effect in terms of slope surface is built the unstable of initial stage and corroded is fine, effect highly significant, but is detrimental to environment
The recovery of protection and ecological environment, over time, the corrosion of atmospheric disintegration of rocks, the aging of concrete, reinforcing bar makes intensity
It reduces, effect also can worse and worse, and maintenance cost also increases, and is difficult to ensure work in heavy rainfall, eugeogenous rock soil area
Journey material is mutually compatible with slope ground body, and engineering structure is easily maked somebody a mere figurehead, and easily leads to the generation of landslide accident.And ecological protection technology
It exactly comes into being under these conditions, it can overcome the disadvantages that the deficiency of traditional defense project post-evaluation, and can satisfy people to ring
The requirement of border protection, the presence of root system of plant make soil have the construction similar to " armored concrete ".
Summary of the invention
The purpose of the present invention is utilizing bamboo plant well developed root system, fast growing, can quickly exist in a Growing season
Root system network is formed in soil horizon, while the tractive force of bamboo plant root system and torsion carry all bigger characteristic, obtain one
Kind carries out the anti-skidding method of three-dimensional slope protection using bamboo plant, to solve disadvantage existing in the prior art.
It is a kind of anti-skidding using the three-dimensional slope protection of bamboo plant progress the purpose of the present invention is what is be achieved through the following technical solutions
Method, comprising the following specific steps
Using red Sinobambusa, Japan's Sinobambusa, Indocalamus Nakai, yin-yang Sinobambusa and bitter bamboo belong to the bamboo kind of a part of mixed type root whip system into
The solid slope of row 0-20cm soil horizon is anti-skidding；
Using bitter bamboo category, Phyllostachys, arrow Sinobambusa, square Sinobambusa, a kind of bamboo Sinobambusa, Bashania, sour Sinobambusa and Indosasa one
Part subterranean stem single-shaft variant or multiple spindle-type, have underground it is horizontal walk a part of bamboo kind of bamboo whip carry out the Joint of Line and Dot of plane space
It is anti-skidding to carry out slope protection, simultaneously because the root whip of these bamboo kinds more deep layer in soil horizon, reaches 40-60cm, while can rise
It is anti-skidding to the solid slope of vertical space.
Compared with prior art, the present invention by adopting the above technical scheme, in the short time (in a growth period), surface layer (0-
20cm) increment of root system is significantly bigger than general draft digitaria ciliaris, the flood land of Horseweed Herb group in soil.With other data
Compare with bibliography, the accumulative speed of root biomass also than tree and shrubs it is fast very much, can be set the goal with rapid anchor
Engineering soil.In short time, Gu slope it is anti-skidding effect it is obvious, the tensile strength and shear strength of stero of the invention
All obtain the promotion of several times and more than ten times.Gu the slope anti-skidding effect time is long, general surface layer by bamboo after the growth period of 3-5
Community competition can be exited, i.e., the effect of earlier surface layer anchoring soil can be replaced by Scattered bamboos.Different Root System Growth Characteristics mix
It is cooperated by bamboo and single-shaft variant Scattered bamboos to raw type, no longer individually pays the utmost attention to the solid slope antiskid effect of topsoil, but
Comprehensively consider its vertical space and chronergy.
Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book is understood other advantages and efficacy of the present invention easily.
In the flood land of 10-20 gradient, by cultivation in 1 year, in the case where 11-18% soil moisture content, 0-20cm
The root system average tensile strength 39.55Mpa of topsoil, the mostly ground of mixed type root whip system are accounted for by bamboo root system, root system fresh weight
The 2.01% of soil fresh weight；The root system average tensile strength 26.42Mpa of 20-40cm, mostly single-shaft variant Scattered bamboos, root system fresh weight
Account for the 1.63% of soil fresh weight；The root system average tensile strength 16.06Mpa of 40-60cm, mostly single-shaft variant Scattered bamboos, root system are fresh
The 0.41% of soil fresh weight is accounted for again.
The small root tensile strength of diameter grade is big: digitaria ciliaris that this test is grown naturally with adjacent place, Horseweed Herb root system phase
Compare, the bamboo kind average fiber cellulose content and tensile strength of this test are respectively in 19.80-24.07% and 30.71-44.60MPa
(0-20cm), and digitaria ciliaris, Horseweed Herb root system content of cellulose and tensile strength that adjacent place is grown naturally exist respectively
20.11-23.63% and 11.55-16.79MPa (0-20cm), shows although average fiber cellulose content is not much different, but tension is strong
It spends widely different.Show that the system that we test has apparent slope antiskid effect admittedly.
Slope antiskid system, soil shear strength enhancement value are mixedly consolidated by the solid space of bamboo and Scattered bamboos in test
It is positively correlated with soil root content, i.e., with the increase of soil root content, the enhancing of soil shear strength.With identical place
River shoal bare area is compared, bare area 0-20cm topsoil shear strength average out to 15.33kPa, 20-40cm topsoil
Shear strength average out to 30.91kPa, 40-60cm topsoil shear strength average out to 51.71kPa；And mixedly by bamboo
Consolidate slope antiskid system 0-20cm topsoil shear strength average out to 28.51kPa, 20-40cm with the solid space of Scattered bamboos
Topsoil shear strength average out to 55.74kPa, 40-60cm topsoil shear strength average out to 57.00kPa.It is each
Soil horizon is obviously improved.
The river shoal soil shear strength of this test compared with the digitaria ciliaris of adjacent river shoal, Horseweed Herb root system, 0-20cm,
Tri- layers of 20-40cm, 40-60cm have increased separately 20.53,49.51 and 46.08kPa, significantly increase shear strength；Root is fresh
It focuses on tri- layers of 0-20cm, 20-40cm, 40-60cm and has increased separately 200.56%, 269.04% and 945.26%.Meanwhile root system
Distribution only embodies in point unlike digitaria ciliaris, Horseweed Herb group, dotted line of this test in vertical structure and topsoil
The spatial network system of root system is preferably built in the structure of face.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should be covered by the claims of the present invention.
