Description
Technical field
The utility model is related to cut slope composite supporting construction, belongs to side slope protection technical field.
Background technology
As the economy of China is developed rapidly, public (iron) road turns the task of the most important thing, incident cutting into
Slope project is more and more.In slope excavating and Bracing Process, different degrees of breaking often is caused to domatic original vegetation
It is bad, a large amount of exposed slight slopes and rock slope are caused, cause serious soil erosion and ecological environment unbalance.At present, environment is asked
Inscribe oneself and move towards global from region, receive significant attention.Slope project implement as cause environmental disruption key factor it
One, how while slope project is implemented, do not destroy domatic original vegetation as far as possible, preserve the ecological environment, as urgently to be resolved hurrily
Problem.
At present in slope project, traditional supporting construction mainly has:Friction pile, retaining wall, prestressed anchor cable frame, anchor
Spray supporting and slope etc..Friction pile or retaining wall construction need large-scale construction equipment, are only used for cut slope bottom of slope supporting and retaining system,
The domatic construction of dense vegetation, is easily destroyed vegetation.Because prestressed anchor cable frame needs the construction reinforced bar concrete on domatic
Vierendeel girder, bolt-spary supports needs the gunite concrete on domatic, and slope can increase excavation scope, therefore above-mentioned three kinds of supporting construction is not
Suitable for the domatic situation that there is dense vegetation.Certainly, also many ecological slope protection structures, but these structures are all mostly destructions
After original vegetation, constructed, finally by manual reversion slope vegetation, deficiency in economic performance.
The technical scheme of prior art one, existing slope retaining structure invention such as expansive soil cut slope support structure and its
Construction method (application number:, including rigid support system, flexible protection systems and waterproof and water drainage system three 201310349461.5)
Point, the rigid support system includes being arranged on the crippled retaining wall of Cut Slopes of Expansive Soil and retaining wall foundation;The flexible support
System include be arranged on Cut Slopes of Expansive Soil sash beam, anchor pole, the flexible netted GSZ being laid on domatic and
It is planted in the vegetation on domatic;The waterproof and water drainage system include be arranged on slope top intercepting ditch or gutter, retaining wall after it is saturating
Draining sewer under water layer, gutter and gutter.
The flexible protection systems of the technology need to set sash beam, anchor pole, laying flexible netted GSZ on domatic
With plantation vegetation, the domatic slope engineering that there is vegetation is not suitable for, especially the domatic feelings that there are dense trees
Condition, the construction of Vierendeel girder can destroy domatic existing vegetation, if the technology is constructed, it is necessary to first destroy existing plant in the case
Quilt, it is to be onstructed finish after, then manual reversion vegetation is unfavorable for saving cost.
The technical scheme of prior art two, existing slope retaining structure invention such as a kind of side slope Anti-sliding stopping structure, (application
Number:201610025414.9), including:Multiple friction piles, multiple friction piles squeeze into the bottom of side slope, and the antiskid side by side
The stable region and unstable region of the embedded side slope of stake;Multiple injected holes, are respectively arranged in side slope, and the injected hole includes outer reaming slip casting
Section and the middle slip casting section connected with the outer reaming slip casting section, the outer reaming slip casting section are located at the unstable region, institute
State middle slip casting section stable connection area and unstable region;And dowel, it is located at the outer reaming slip casting section and the middle note
Between slurry section;Wherein, toward slip casting in the injected hole, make slurries in the outer reaming slip casting section and the middle slip casting section with
The dowel condenses into the anchor pole of fixed slope.
The technology sets anchor pole, and reaming slip casting on domatic, but is not connected each other between anchor pole, when side slope is led
When drawing formula displacement, i.e., the land movement of side slope bottom is big, and the land movement of side slope top is small, easily produces drawing crack at domatic middle part
Seam, rainwater enters gap, produces water pressure, is unfavorable for stability of slope.
