Be labeled as in figure: 1-block stone net cage masonry, 2-antislide pile, 3-deep filter guiding gutter and antiskid toe of wall, 4-rubble filtration beds, 41-5-10mm Stone filtration beds, 42-10-20mm Stone filtration beds, 43-20-50mm Stone filtration beds, 7 basal surfaces.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1 and Figure 2, large-scale loose ground of the present invention, stone body slope protection structure, first basal surface is determined, basal surface is fixed with one group of antislide pile 2, below antislide pile 2 basement face, pile up and have block stone net cage masonry 1 around antislide pile 2, block stone net cage masonry 1 is that the material of high seepage of water is made, such as connect into a cuboid by six net cage sheets, and be filled with stone wherein.Net cage sheet is that flexible material is made, and such as nylon material, high density polyethylene (HDPE) etc., have some strength and toughness, has good seepage of water simultaneously.The side of block stone net cage masonry 1 for treating protection side slope, opposite side is rubble filtration beds 4.Antislide pile 2 can have rigid material to make, such as stone column, and the reliability of use considered by steel concrete, the antislide pile 2 of preferred Reinforced Concrete Materials.
Due to the high seepage of water of macadam and quick net cage masonry, the water that heavy rain situation slope is assembled is by rubble filtration beds 4 and block stone net cage masonry 1, the water in the body of slope can be discharged quickly and effectively, make it not become the external factor causing side slope or landslide failure or slip.Antislide pile 2 is wherein the core friction skidding devices in whole protection system, because block stone net cage masonry 1 is flexible structure, antislide pile 2 is rigid structures, the two common composition hard and soft protection system, the structure of antislide pile 2 and (rock) degree of depth of burying can depending on the sliding force of side slope or sliding mass and basement lithologies.Macadam filtration beds comprises three layers of particle diameter respectively at the rubble of 5 ~ 10mm, 10 ~ 20mm, 20 ~ 50mm, and as shown in Figure 3, macadam can protect block stone net cage masonry 1, prevents blocking, and it also possesses good seepage of water simultaneously, can assist draining.
Under basal surface, offer deep filter guiding gutter and antiskid toe of wall 3, deep filter guiding gutter and antiskid toe of wall 3 are horizontally through rubble filtration beds 4, antislide pile 2, block stone net cage masonry 1, and extend to the opposite side of block stone net cage masonry 1.Deep filter guiding gutter and antiskid toe of wall 3, for being opened in the tank under basalis, are filled with rubble in tank.It can discharge the ponding in the body of slope quickly and effectively, and be also the important setting of protection system resistant slide, it can also can locally be arranged in elongated setting, is determined on a case-by-case basis simultaneously.
Large-scale loose ground, stone body side slope, because loose so very easily absorb water and store water, effect due to water makes loose soil (stone) body looser, and intensity greatly reduces, be more prone to unstability or slip, thus a class side slope or landslide easy especially rainy season especially for a long time rainfall time unstability or slip; Meanwhile, because loose, its cohesive strength is very little or go to zero, and also just says that the intensity of soil (stone) body self is very low, so under external force, as very easily unstability or slip under earthquake or artificial destruction condition.
Water in the body of slope can be discharged by block stone net cage masonry 1 and rubble filtration beds 4 by the present invention quickly and effectively.The filter guiding gutter of substrate and antiskid toe of wall can discharge rapidly the ponding of the dark bottom of slope body, can reduce native stone water content in time, avoid the objective condition occurring landslide.Meanwhile, each piece of stone net cage masonry forms the junior unit that has some strength and toughness, and the sliding force of slide mass can be dissipated and absorb to its distortion, can resist the effect of external force within the specific limits.Jointly the mutually soft protection system helped mutually is formed with flexible block stone net cage masonry 1 by the reinforced concrete anti-slide pile 2 of rigidity, the deformation range of flexible masonry is larger, the deformation failure lasting one " long period " is needed when destroying completely so under external force, this just provides the early warning of " long period " for " dam break " of dam body, it so just can be made to destroy and the loss that produces reduces to minimum.Its medium and deep filter guiding gutter and antiskid toe of wall 3 intersect with masonry, and not only getting rid of the moisture of masonry in time, is also the important setting of protection body resistant slide.
Large-scale loose ground, stone body method, comprise the following steps:
A. according to side slope or Landslide report, basal surface absolute altitude is determined;
B. according to exploration report, calculate soil pressure, determine the physical dimension of reinforced concrete anti-slide pile, arrangement of reinforcement, bury or enter the rock degree of depth etc., determine the physical dimension of block stone net cage masonry;
C. calculate according to the resistant slide on side slope or landslide, determine that the physical dimension of guiding gutter and antiskid toe of wall is filtered in deep and whether elongated laying is still laid local.
Concrete calculating and form of construction work can with reference to " Code for design of concrete structures " and " technical code for building pile foundation ".
