Abstract
The utility model discloses an excavation slope supporting structure for sloping construction. The excavation slope supporting structure comprises a fine aggregate concrete base layer and geogrid, wherein the fine aggregate concrete base layer is sprayed on the excavation slope, and the geogrid is laid on the fine aggregate concrete base layer. The geogrid is fixed on the excavation slope. A fine aggregate concrete surface layer is sprayed on the geogrid. A reinforcing function can be achieved by the excavation slope supporting structure on the excavation slope effectively, and effects of soil body stress homogenization, excavation slope deformation restraining and the like are good. The excavation slope supporting structure has the advantages of being good in stability after molded, capable of keeping stability of the excavation slope after rain wash, easy in material obtaining, easy and convenient to construct, small in requirements of manpower and machinery, capable of improving economic benefits, safe in effects and notable in social benefits.
Description
Technical field
The utility model relates to a kind of foundation pit stope support structure, particularly relates to a kind of foundation pit stope support structure be used to putting the slope construction.
Background technology
The continuous propelling of urbanization process causes the land resources growing tension, and the swift and violent universal contention that has aggravated city parking position of the various vehicles, and the design of Underground Garage in large area becomes inexorable trend.
Foundation ditch is put slope excavation because of its economy, have a wide range of applications at the realm of building construction, but because of the difference of on-the-spot soil property situation, if do not take corresponding measure, it is very easily accidents caused that non-support is put the slope excavation, causes unnecessary loss.
The utility model content
The utility model provides a kind of foundation pit stope support structure be used to putting the slope construction for solving the technical problem that exists in known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of foundation pit stope support structure be used to putting the slope construction, comprise the pea gravel concreten bottom that is injected on described excavation slope and the geo-grid that is laid on described pea gravel concreten bottom, described geo-grid is fixed on described excavation slope, and spraying on described geo-grid has the pea gravel concreten surface layer.
Toe place at described excavation slope is provided with apron slope and coupled annular french drain, and described annular french drain is communicated with collecting well.
Be provided with apron slope and coupled gutter at the Po Dingchu of described excavation slope.
Described geo-grid is fixed on described excavation slope by fixture.
Described fixture is U-shaped that is made by reinforcing bar, and length is not less than 300mm.
Described geo-grid is formed by the synthetic fibers braiding.
Advantage and the good effect that the utlity model has are: can play effective reinforcement effect to side slope, there is good effect the aspects such as homogenizing resistance to shear of soil, constraint slope deforming.The utility model moulding rear stability is good, still can keep stability of slope after rain drop erosion, and material is easy to get, easy construction, and is artificial, the mechanical requirements amount is little, can greatly increase economic efficiency, and safe effect and social benefit are remarkable.

Fig. 3 is the structural representation of the utility model fixture.
In figure: 1, excavation slope, 2, the gutter, 3, apron slope, 4, french drain, 5, geo-grid, 6, the pea gravel concreten bottom, 7, the pea gravel concreten surface layer, 8, fixture.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1～Fig. 3, a kind of foundation pit stope support structure be used to putting the slope construction, comprise the pea gravel concreten bottom 6 that is injected on described excavation slope 1 and the geo-grid 5 that is laid on described pea gravel concreten bottom 6, described geo-grid 5 is fixed on described excavation slope 1, and spraying on described geo-grid 5 has pea gravel concreten surface layer 7.Toe place at described excavation slope 1 is provided with apron slope and coupled annular french drain 4, and described annular french drain 4 is communicated with collecting well, by submersible pump, current is discharged foundation ditch.Can prevent the landslide that toe is caused by the rainwater erosion.In order to prevent that rainwater, surface water from pouring into foundation ditch from the top, slope.Be provided with apron slope 3 and coupled gutter 2 at the Po Dingchu of described excavation slope 1.Can make surface water form functional in organized water drainage.
Before doing supporting and protection structure, reply excavation slope 1 is repaired, and requires slope leveling, and sloping coefficient meets designing requirement.Above-mentioned pea gravel concreten bottom 6 can adopt the C20 fine-stone concrete to form.After 1 finishing of described excavation slope is completed, with special tool with the C20 fine-stone concrete from bottom to top vertical foundation pit side slope 1 spray on excavation slope 1, jet thickness requires uniformity, forms pea gravel concreten bottom 6.Described geo-grid 5 is formed by the synthetic fibers braiding, and its size of mesh opening is 25.4mm * 25.4mm.After 6 injections of pea gravel concreten bottom are completed, described geo-grid 5 is laid from bottom to top along side slope 1, at the rotation angle position of side slope 1, geo-grid 5 short lap length are not less than 500mm, and all the other positions are not less than 200mm; 4 of excavation slope 1 and french drains, geo-grid 5 is all laid by slope aspect in 2, side slope 1 and gutter.Described geo-grid 5 is fixed on described excavation slope 1 by fixture 8.The desirable on-the-spot reinforcing bar waste material self-control of described fixture 8 becomes length to be not less than " U " type spare of 300mm the reinforcing bar waste-material-preparing.Geo-grid 5 is being detained grid with described fixture 8 and is being hammered into excavation slope 1 after laying and completing, and fixture 8 is rule to be arranged, can suitably encrypt at geo-grid 5 overlapping parts.Described pea gravel concreten surface layer 7 can adopt the C20 fine-stone concrete to form.Lay in geo-grid 5 and complete, and fixing with fixture 8, and after qualified by inspection, with special tool with the C20 fine-stone concrete from bottom to top vertical geo-grid 5 spray on geo-grid 5, jet thickness requires uniformity, formation pea gravel concreten surface layer 7.After pea gravel concreten surface layer 7 sprays and completes, the operation construction of lower step of must being allowed for access after being no less than maintenance in 24 hours.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, within these all belong to protection domain of the present utility model.
