Description
Technical field
The present invention relates to side slope protection technical field.
Background technology
Small-sized loose ground (stone) body side slope or landslide is all little using which kind of means of defence problem.But if
Especially come down for large-scale or huge side slope, it is always one, Geotechnical Engineering field difficulties that it, which is protected,.Why be
Difficulties are because of following 2 points：First, traditional method is often difficult to effectively solve this problem, it is very big to run into rainfall
Situation, timeliness is often protected, cause the loss of personnel, property, second, traditional method can solve but cost is too high and basic
It can not realize.How to efficiently solve these problems is Geotechnical Engineering field urgent problem to be solved.
The content of the invention
Technical problem solved by the invention is to provide a kind of large-scale loose ground, Shi Ti for the loose large-scale side slope of quality
Slope protection structure and method.
The technical solution adopted by the present invention is large-scale loose ground, stone body slope protection structure, including one group of friction pile, is resisted
Below the basement face of sliding pile lower end, being piled up around friction pile has block stone net cage masonry, and block stone net cage masonry is wrapped up by net cage
Stone is made.
The side of block stone net cage masonry is side slope to be protected, opposite side is provided with rubble filter layer, and rubble filter layer is laid in
The side of block stone net cage masonry.
Deep filter guiding gutter and antiskid toe of wall are offered under basal surface, deep filter guiding gutter and antiskid toe of wall are horizontally through
Rubble filter layer, friction pile, block stone net cage masonry, and extend to the opposite side of block stone net cage masonry.
Include at least three layers of rubble on the rubble filter layer, ballast grain sizes it is maximum be located at innermost layer, ballast grain sizes by
It is up to lower to increase.
Include three layers of rubble on the rubble filter layer, the particle diameter of three layers of rubble be respectively from top to bottom 5~10mm, 10~
20mm, 20~50mm.
It is the tank being opened under basalis that guiding gutter and antiskid toe of wall are filtered in deep, and rubble or stone are filled with tank.
Block stone net cage masonry connects into a cuboid by six net cage pieces, and is filled with stone wherein.
The beneficial effects of the invention are as follows can be quickly and effectively by the water in slopes by block stone net cage masonry and rubble filter layer
Discharge, avoid landslide from occurring, the protection body of mutually soft phase Ji is collectively constituted by the block stone net cage masonry of rigid friction pile and flexibility
System, can be reasonably resistant to the effect of external force, the sliding force of slide mass, Er Qierou can be dissipated and be absorbed to the deformation of flexible protective body
Property masonry deformation range it is larger, more sufficient pre-warning time can be provided, substrate filter guiding gutter and antiskid toe of wall both
The ponding of slopes depth bottom can be discharged rapidly, while is also the important setting of protection body resistant slide.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, large-scale loose ground of the invention, stone body slope protection structure, it is first determined basal surface, substrate
It is fixed with one group of friction pile 2 on face, below the basement face of friction pile 2, being piled up around friction pile 2 has block stone net cage masonry 1,
Block stone net cage masonry 1 is made up of the material of high seepage of water, such as connects into a cuboid by six net cage pieces, and fills out wherein
Filled with stone.Net cage piece is made up of flexible material, such as nylon material, high density polyethylene (HDPE) etc., has some strength and toughness,
There is good seepage of water simultaneously.The side of block stone net cage masonry 1 is side slope to be protected, opposite side is rubble filter layer 4.Antiskid
Stake 2 can have rigid material to be made, such as stone column, armored concrete, it is contemplated that the reliability used, preferably Reinforced Concrete Materials
Friction pile 2.
Due to the high seepage of water of metalling and quick net cage masonry, the water of heavy rain situation slope aggregation is filtered by rubble
Layer 4 and block stone net cage masonry 1, can quickly and effectively discharge the water in slopes, make its do not turn into cause side slope or landslide failure or
The external factor of slip.Friction pile 2 therein is the core friction skidding device in whole protection system, because block stone net cage masonry 1
It is flexible structure, friction pile 2 is rigid structure, and the two collectively constitutes hard and soft protection system, the structure of friction pile 2 and is buried
(rock) depth can be depending on the sliding force and basement lithology of side slope or slip mass.Metalling filter layer includes three layers of particle diameter and distinguished
5~10mm, 10~20mm, 20~50mm rubble, as shown in figure 3, metalling can protect block stone net cage masonry 1, prevent
Block, while it also possesses good seepage of water, can assist draining.
Deep filter guiding gutter and antiskid toe of wall 3 are offered under basal surface, deep filter guiding gutter and antiskid toe of wall 3 are laterally worn
Rubble filter layer 4, friction pile 2, block stone net cage masonry 1 are crossed, and extends to the opposite side of block stone net cage masonry 1.Filter water guide in deep
Groove and antiskid toe of wall 3 are the tank being opened under basalis, and rubble is filled with tank.It quickly and effectively can be discharged in slopes
Ponding, while be also the important setting of protection system resistant slide, it also can locally be set with elongated setting, depending on concrete condition
It is fixed.
Large-scale loose ground, stone body side slope because loose easily absorb water and store water, due to the effect of water make it is loose
Native (stone) body is looser, and intensity is greatly lowered, and is more prone to unstability or slip, so a kind of side slope or landslide are particularly easy to
Unstability or slip in rainy season especially prolonged rainfall；Meanwhile because loosely, its cohesive force very little or go to zero, also
Say that the intensity of native (stone) body itself is very low, so under external force, such as easily unstability or cunning under the conditions of earthquake or artificial destruction
It is dynamic.
The present invention quickly and effectively can be discharged the water in slopes by block stone net cage masonry 1 and rubble filter layer 4.Substrate
Filter guiding gutter and antiskid toe of wall can discharge the ponding of slopes depth bottom rapidly, can reduce native stone water content in time, avoid out
The objective condition now to come down.Meanwhile each block stone net cage masonry forms a junior unit with some strength and toughness, it becomes
Shape can dissipate and absorb the sliding force of slide mass, can resist the effect of external force within the specific limits.Mixed by rigid reinforcing bar
The block stone net cage masonry 1 for coagulating native friction pile 2 and flexibility collectively constitutes the protection system that mutually soft phase is helped, the deformation range of flexible masonry
It is larger, then to need to last the deformation failure of one " long period " when destroying completely under external force, this is just dam body
" dam break " provides the early warning of one " long period ", can thus make its destroy and it is caused loss be reduced to minimum.Its
Medium and deep filters guiding gutter and antiskid toe of wall 3 intersects with masonry, not only excludes the moisture of masonry, and protection body resistant slide in time
Important setting.
Large-scale loose ground, stone body method, comprise the following steps：
A. reported according to side slope or Landslide, determine basal surface absolute altitude；
B. according to exploration report, calculate soil pressure, determine the physical dimension of reinforced concrete anti-slide pile, arrangement of reinforcement, bury or
Enter rock depth etc., determine the physical dimension of block stone net cage masonry；
C. according to the resistant slide on side slope or landslide calculate, determine deep filter guiding gutter and antiskid toe of wall physical dimension and
Whether elongated still part of laying is laid.
Specific calculate may be referred to form of construction work《Code for design of concrete structures》With《Technical code for building pile foundation》.
