Description
Technical field
The utility model relates to a kind of slope retaining structure, belongs to the side slope support technology fields such as Hydraulic and Hydro-Power Engineering, mine engineering, highway engineering.
Background technology
In current slope support engineering, for preventing slope failure, generally many anchor poles, dowel bundle etc. are set in side slope, and at anchor pole, fill up cement mortar between dowel bundle and bolthole, guarantee that the rock mass that anchor pole, dowel bundle and periphery are discrete or native stone consolidation are chained together, meanwhile, steel fibre reinforced concrete is sprayed to reach the object of stability of slope at side slope surface.But, for rock slope, the general crack of slope body, joint aspect even mature fault, supporting is carried out according to anchor pole, dowel bundle and spray steel fibre reinforced concrete, the rock mass series winding of the crack that it only can pass by anchor pole, dowel bundle, tomography, rock mass between anchor pole and anchor pole is still in discrete state, taking domatic spray steel fibre reinforced concrete to guarantee, discrete rock does not slide drops, but steel fibre reinforced concrete construction technology is numerous and diverse, construction period is long, drop into more human and material resources resource, increase construction investment; In addition, for soil-slope, because the soil body is soft, easily slip unstability, mud-rock flow phenomenon is produced after meeting rainwater, take anchor pole, dowel bundle and spray steel fibre reinforced concrete to be difficult to stop domatic slip, if arrange retaining wall at side slope toe, only can guarantee that Slope foot bottom does not slide, top still cannot be stoped to produce landslide phenomenon, have a strong impact on slope project safe operation.In sum, current slope retaining is passive protecting pattern.
Utility model content
The purpose of this utility model is to provide the slope retaining structure that a kind of working procedure is simple, construction speed is fast, supporting effect is good.
The utility model is a kind of slope retaining structure, comprise side slope, described side slope is rock side slope or soil-slope, comprise the insufflate concrete being arranged on side slope surface, insufflate concrete is generally the dry-mix concrete being not less than C20 tension, compressive strength index, insufflate concrete thickness is generally 5 ~ 15cm, insufflate concrete thickness is generally 5 ~ 15cm, insufflate concrete is too thin easily produces cracking, damaged or punch-through under the effect of consolidation grouting pressure, make grouting slurries ooze out domatic, consolidation grouting construction quality is difficult to ensure.Otherwise, insufflate concrete too thick increase engineering construction difficulty, and cause engineering material to waste, increase construction investment.
In side slope, arrange several consolidation grouting holes, consolidation grouting pitch of holes and hole depth are generally determined by the degree of crushing of side slope or soil property loosening degree, and spacing is generally 1.5 ~ 3.0m, the general 3.0 ~ 9.0m of hole depth.In each consolidation grouting hole, bury a mesh steel pipe underground, the body of described mesh steel pipe is provided with multiple netted hole to ensure that grouting slurries can enter in side slope through mesh.Mesh steel pipe possesses certain rigidity, body is provided with multiple in netted hole, slurries of can guaranteeing effectively to be like this in the milk can be spread in cavity in side slope, crack, joint aspect and interlayer, tomography equably, between loose block of stone in the body of slope or be mutually bonded together after backfilling cement slurries in the soil body, cohesion improves and improves, and reaches the object of stability of slope supporting.Because mesh steel pipe possesses certain rigidity, the extruding of periphery rock and the soil body can not only be born and indeformable, guarantee carrying out smoothly of grouting construction, simultaneously, the mesh steel pipe later stage can substitute the effect of anchor pole, the rock block mutually departed from side slope and soil body anchoring are concatenated, stability of slope supporting effect is better, the powerful guarantee safe operation of side slope.
The beneficial effects of the utility model are:
Compared with prior art, the utility model can meet slope retaining requirement preferably, first take to arrange insufflate concrete at side slope surface, insufflate concrete can bond firmly with side slope surface, play good sealing effect, heavy rain and flood can not infiltrate slope body and produce the phenomenons such as landslide and mud-rock flow.When carrying out consolidation grouting by the mesh steel pipe be embedded in consolidation grouting hole to slope body, insufflate concrete possesses comparatively high tensile, compressive strength, can not ftracture under the effect of certain consolidation grouting pressure, damaged or puncture, grouting slurries in the body of slope from domatic outflow, can not save the input of engineering material.The utility model slope retaining structure construction technology is simple, and construction speed is fast, and reduced investment, also reaches good supporting effect, can in side slope support technology field wide popularization and application such as Hydraulic and Hydro-Power Engineering, mine engineering, highway engineerings.

Description of reference numerals: 1-side slope, 2-insufflate concrete, 3-consolidation grouting hole, 4-mesh steel pipe.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, slope retaining structure of the present utility model comprises the insufflate concrete 2 being arranged on side slope 1 surface, arranges consolidation grouting hole 3 in side slope 1, is embedded with mesh steel pipe in consolidation grouting hole 3.In the technical program, because insufflate concrete 2 is arranged at side slope 1 surface, bonds firmly with side slope 1, play good sealing effect after insufflate concrete 2 solidifies, heavy rain and flood can not infiltrate generation in side slope 1 and come down and the phenomenon such as mud-rock flow.And insufflate concrete 2 possesses certain tension, compressive strength index, when can not pressurized and produce cracking, damaged or punch-through to insufflate concrete 2 when carrying out consolidation grouting in side slope 1.
In addition, owing to arranging consolidation grouting hole 3 and bury mesh steel pipe 4 underground in side slope 1 in consolidation grouting hole 3, mesh steel pipe 4 is provided with multiple netted hole, slurries of can guaranteeing effectively to be in the milk can be spread in cavity in side slope 1, crack, joint aspect and interlayer, tomography equably, between loose block of stone in side slope 1 or be mutually bonded together after backfilling cement slurries in the soil body, cohesion improves and improves, and reaches the object that side slope 1 stablizes supporting.
In addition, because mesh steel pipe 4 possesses certain rigidity, the extruding of periphery rock and the soil body can not only be born and indeformable, guarantee carrying out smoothly of grouting construction, meanwhile, mesh steel pipe 4 later stage can substitute the effect of anchor pole, the rock block mutually departed from and soil body anchoring is concatenated in side slope 1, it is better that side slope 1 stablizes supporting effect, the powerful guarantee safe operation of side slope 1.
The utility model slope retaining structure progress is fast, reduced investment, and working procedure is simple, also reaches good supporting effect, can in side slope technical field wide popularization and application such as Hydraulic and Hydro-Power Engineering, mine engineering, highway engineerings.
Certainly, more than just embody rule example of the present utility model, the technical scheme that the utility model also has other embodiment, all employings to be equal to replacement or equivalent transformation to be formed, all drops within the protection domain required by the utility model.
