Abstract
A kind of abrupt slope rockfall structure of blocking including the reinforcing pile being arranged at intervals on abrupt slope further includes gear slabstone and buffer layer, and gear slabstone is arranged between adjacent reinforcing pile, and buffer layer setting is in gear slabstone upper side.The utility model has the advantage that can effectively solve abrupt slope rockfall blocks difficulty, and it is easy for construction, investment is low, environmentally friendly, have broad application prospects and be worth.
Description
Technical field
The utility model relates to geotechnical engineering, in particular to a kind of abrupt slope rockfall is blocked structure.
Background technique
Rockfall is largely distributed in mountain area, and the common rockfall protection measure of blocking has stone cut off wall and passive protection
Net, both measures are applied when on abrupt slope, and the measure effect of blocking of setting is bad；The setting height of stone cut off wall and protective net has
Limit, thus it is difficult to stone of endangering of effectively blocking.Also there is setting piling wall stone cut off wall structure in engineering, although the height of stake is adjustable,
But meet effect of blocking, the pile body structure of setting needs very big sectional dimension and setting depth, thus construction investment is very high.
Therefore it is badly in need of a kind of new abrupt slope rockfall and blocks structure, and there is easy for construction, good economy performance, environmental protection and application value
The features such as.
Utility model content
The purpose of this utility model is just to provide a kind of abrupt slope rockfall and blocks structure, can effectively solve abrupt slope crag
Falling rocks is blocked difficulty, and invests low, is furthermore had broad application prospects and is worth.
The purpose of this utility model is achieved in that a kind of abrupt slope rockfall is blocked structure, including is arranged at intervals on
Reinforcing pile on abrupt slope further includes gear slabstone and buffer layer, and gear slabstone is arranged between adjacent reinforcing pile, and buffer layer setting is being kept off
Slabstone upper side.
In the present invention, using reinforcing pile as the force structure of stone falling rocks of endangering of blocking, setting height is adjustable, blocks
Keep off large carrying capacity；Using the gear slabstone being arranged between reinforcing pile as stone structure is blocked, avoid rockfall from reinforcing pile it
Between roll out；Buffer layer is set between rockfall and reinforcing pile and gear slabstone, weakens rockfall to reinforcing pile and gear slabstone
Unfavorable percussion, substitute traditional buffer layer that bankets, so that reinforcing pile stress is smaller, therefore depth minus is arranged in reinforcing pile
It is small, save construction investment；The structure solves the problems, such as that abrupt slope rockfall is blocked difficult and high investment, and have,
The features such as good economy performance, environmental protection and application value.
By adopting the above-described technical solution, the utility model has the advantage that can effectively solve abrupt slope crag falls
Stone is blocked difficulty, and it is easy for construction, investment is low, environmentally friendly, have broad application prospects and be worth.
Detailed description of the invention
The Detailed description of the invention of the utility model is as follows:
Fig. 1 is that the utility model abrupt slope rockfall is blocked a kind of sectional schematic diagram of structure；
Fig. 2 is that the utility model abrupt slope rockfall is blocked another sectional schematic diagram of structure.
In figure: 1. reinforcing piles；2. keeping off slabstone；3. buffer layer；4. anchor cable；5. abrupt slope；6. free end.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As depicted in figs. 1 and 2, a kind of abrupt slope rockfall is blocked structure, including the reinforcing pile being arranged at intervals on abrupt slope 5
1, it further include gear slabstone 2 and buffer layer 3, gear slabstone 2 is arranged between adjacent reinforcing pile 1, and the setting of buffer layer 3 is on gear slabstone 2
Square side.
In the present invention, using reinforcing pile 1 as the force structure of stone falling rocks of endangering of blocking, setting height is adjustable,
It blocks large carrying capacity；Using the gear slabstone 2 being arranged between reinforcing pile 1 as stone structure is blocked, avoid rockfall from reinforcing
It is rolled out between stake 1；Buffer layer is set between rockfall and reinforcing pile 1 and gear slabstone 2, weakens rockfall to reinforcing pile 1
With the unfavorable percussion of gear slabstone 2, traditional buffer layer that bankets is substituted, so that 1 stress of reinforcing pile is smaller, therefore reinforcing pile 1
Depth is arranged to reduce, saves construction investment；The structure efficiently solves 5 rockfall of abrupt slope and blocks difficult and high investment ask
Topic, and have the characteristics that easy for construction, good economy performance, environmental protection and application value.
Further, as shown in Fig. 2, being additionally provided with the anchor cable 4 connecting with reinforcing pile 1；The free end 6 of anchor cable 4 and reinforcing pile 1
Top is affixed, and the other end is arranged in 5 slopes of abrupt slope.By the way that prestress anchorage cable 4 is arranged in 1 stake top of reinforcing pile, it can improve and add
Gu the stress of stake 1, the embedded depth so as to greatly increase the setting height of reinforcing pile 1, without increasing reinforcing pile 1
Degree, therefore 1 construction investment of reinforcing pile reduces, protection height is adjustable, and protection effect is good.
Further, buffer layer 3 is waste tire.The utilization of waste tire can save while reaching environment protecting
About cost.
Further, the spacing between adjacent reinforcing pile 1 is 6~8m, and buried depth is greater than or equal to 4m.The spacing of 6~8m can
To have better support to gear slabstone 2, and buried depth can greatly enhance the bearing capacity of reinforcing pile 1 more than or equal to 4m.
Further, gear slabstone 2 is fixedly connected with reinforcing pile 1, is additionally provided with drainage gallery in gear 2 bottom of slabstone.Keep off slabstone 2
The ability of stone falling rocks of endangering of blocking that gear slabstone 2 can be enhanced is fixedly connected with reinforcing pile 1, and the setting of drainage gallery can make
Rainwater etc. passes through, and reduces rainwater etc. to the impact force of gear slabstone 2, and makes overall structure more firm.
Further, reinforcing pile 1 is cylindrical body, cube or other shapes.
Further, reinforcing pile 1 is powder-spray pile, mixing pile or broken stone pile.Powder-spray pile is deep mixing method consolidated subsoil side
A kind of form of method is the method using powder shaped curing agent to carry out soft base stir process.It is suitable for reinforcing the various origin causes of formation
Saturated soft clay, China are usually used in reinforcing mud, muck soil, silt and the higher cohesive soil of water content；Mixing pile is to be used for
A kind of method of saturation soft clay low land base is reinforced, it is using cement as curing agent, by special Mixing Machine, in ground
Weak soil and curing agent action of forced stirring are chemically reacted using a series of physical generated between curing agent and weak soil, are made by depths
Weak soil hardens into the high-quality ground with globality, water stability and some strength；It is main that broken stone pile, which is with rubble (cobble),
Composite foundation stabilization stake made of material.
