Technical field
The invention belongs to subgrade engineering side slope protection technical field, it is related to a kind of ecological skeleton bank protection of roadbed side slope and makes dress
Put.
Background technology
In recent years, investment steady growth of the country to railway, highway, traffic base construction has welcome peak period, a plurality of new
Circuit is built to give an written reply in succession and open-minded.Roadbed directly affects road as carrying top static load and the direct organization of dynamic load, its quality
The service life on road, and the side slope protection for strengthening roadbed is the important step for ensureing roadbed quality, if slope protection measures are not
When, under rain drop erosion and eolian erosion, the destruction of side slope will be accelerated, and then cause a series of subgrade defect, influence is gone
The safety and comfort level of car, while increasing the maintenance management expense of road.Therefore, the side slope protection for strengthening roadbed is significant.
Roadbed side slope protection is broadly divided into engineering protection and the major class of plant protection two.Engineering protection is that traditional protection is arranged
Apply, mainly include sash protection, front cover, facing wall, dry-laid rubble bank protection, mortar rubble masonry pavement, grout prefabricated section bank protection, anchor pole
Steel wire whitewashing, gunite concrete bank protection etc., have the advantages that the good, instant effect of protection effect at initial stage, short time limit, but to natural ring
The destructiveness in border is big, ecological environment benefit extreme difference.Plant protection is also referred to as ecological protection, is a kind of novel protective measure, mainly
Including kind of a grass, turfing, tree planting etc., generally as the ancillary method of engineering protection, with protection cycle length, coordination of landscape, culvert
The features such as supporting water source, but with limitation, early stage needs continuous maintenance.
In recent years, concrete hollow hexagonal bank protection skeleton is due to having the advantages that easy construction, instant effect are widely used
In roadbed side slope protection, but it is uncoordinated with surrounding landscape and environment, has not both met the energy-saving and emission-reduction policy of country's promotion, also not
Meet the living environment for the ecological, environmental protective that the modern common people pursue, therefore, the similar ecological revetment skeleton of development becomes one kind and become
Gesture.
The content of the invention
It is an object of the invention to provide a kind of ecological skeleton bank protection producing device of roadbed side slope, it can make and surrounding landscape
And environmental harmony, both meet energy-saving and emission-reduction policy, and also comply with the biological hexagonal for the ecological, environmental protective living environment that the modern common people pursue
Bank protection skeleton.
To achieve the above object, the technical solution adopted in the present invention is：A kind of ecological skeleton bank protection of roadbed side slope makes
Device, including base, inner cylinder, outer barrel, crossbeam, screw mandrel, gland and two pull bars；
Described base includes the limited block for the spacing collar, two pulling seats and two " L " shapes that annular is connected with bottom plate, bottom plate,
Two limited blocks and two pulling seats are symmetrical arranged both with respect to spacing collar, and limited block is located between spacing collar and pulling seat；Limited block
There is space between spacing collar；Outer barrel is tubular, and the inner and outer wall of outer barrel is positive six prismsby；When using：Inner cylinder is enclosed on limit
On the circle of position, then, outer barrel is coaxially disposed with inner cylinder, outer barrel is located between limited block and inner cylinder, has between outer barrel and inner cylinder
Cavity, by bearing pin cylinder lever connecting rod and pulling seat, two pull bars are connected by crossbeam, and crossbeam is connected with wire rod thread, on screw mandrel
Pressure head penetrate in gland.
Ecological hollow hexagonal block the nutrient matrix mixed and stirred can be made in producing device of the present invention.When ecological hollow hexagonal block
Meet after design strength, be placed in side slope, early stage stable side slope, after providing Nutrient medium after later stage plant survival for it
Matter.
