Description
Technical field
The utility model relates to Geotechnical Engineering field, relating in particular to a kind of Stability of Earth Slopes reinforces and supporting and protection structure, (may slide at dangerous slopes, slide) region, set vertical root pile soil-baffling structure by fracture grouting, and by stake head piece and the combination of oblique soil bolt, form compound soil-baffling structure, greatly improve and reinforce and support capacity.
Background technology
Soil-baffling structure, can be described as again supporting and protection structure, and space enclosing structure is mainly used in stability of slope in geotechnical engineering field, pattern foundation pit supporting structure, cavern excavation, coastal engineering.Have multi-form according to its effect field difference: in the time being mainly used in stability of slope, have retaining wall, antislide pile, the forms such as anchored bolt retaining wall; In the time of supporting for excavation of foundation pit, there is cantilevered space enclosing structure, gravity wall, inner bearing type space enclosing structure, draws anchor formula space enclosing structure, soil nail wall space enclosing structure and gantry type, open caisson, arch formula combined enclosure, spray anchor net is gone along with sb. to guard him etc.; In coastal engineering, mainly contain sheet pile wing wall, mole etc.; In cavern excavation engineering, there is lining cutting, vertical supporting etc.
At present, stability of slope structure has a lot, and conventional have antislide pile, anchor pole, a retaining wall.Antislide pile stake footpath is large, and difficulty of construction is large, and cost is high, large to soil layer disturbance, and work plane requires high.Anchor pole is to simple soil layer, and small-sized slight slope landslide antiskid effect is obvious, unstable to major landslip effect.Rigid retaining wall earthwork excavated volume is large, and disturbance is large, need to excavate base plate, and cost is high.And to there is the region on landslide, excavation slight slope can cause the further increasing on landslide.How effectively to administer landslide and soil layer around landslide do not caused to large disturbance, avoiding further destruction, and how to improve efficiency of construction, convenient construction, cost-saving is to need to consider.
In view of traditional soil-baffling structure exists cost high, difficulty of construction is large, cost is higher and the low grade of efficiency is not enough, taking into full account the horizontal anti-slide performance of root pile and the tensile property of anchor pole, the utility model proposes the compound soil-baffling structure of a kind of anchor pole-root pile, can give full play to the self-stable ability of the landslide soil body, and cost is low, easy construction, Space is obvious.And to expansive soil slope, the root pile that fracture grouting is technical foundation can form the compound soil body, increase the anti-slide performance of root pile.In addition, root pile easy construction, establishes a position flexible, little to soil layer disturbance; Special secondary high-pressure slip-casting technology in root pile work progress, the stake Zhou Fuhe soil body forming through fracture grouting, can make pile body be anchored at reliably in the soil body and improve soil strength.
Summary of the invention
The utility model provides a kind of anchor pole-root pile compound soil-baffling structure, by double root pile is set as vertical soil-baffling structure in side slope, form compound soil-baffling structure by stake head piece and soil bolt, can give full play to soil layer self-stability, effectively solve in soil-slope generation unstability preventing land slide conventional antislide pile excavation face excessive, strong to the disturbance of side slope soil layer, the problems such as constructional difficulties, and can effectively reduce costs, raise the efficiency.
In order to address the above problem, the utility model adopts following technical scheme:
The compound soil-baffling structure of a kind of anchor pole-root pile, comprises by the double root pile as vertical soil-baffling structure with as the lateral tilt anchor pole of outer pull system, connects and along the loosening elongated layout of soil body scope in the landslide that needs regulation by stake head piece.Between crossbeam and root pile, adopt hinged connected mode, being connected between crossbeam and anchor pole is to be rigidly connected; As the soil bolt of outer pull system, its one end is connected with root pile by stake head piece, and the other end is anchoring body, and anchoring body is located in steady soil; Root pile stake top adopts cast-in-situ concrete crossbeam that root pile and anchor pole are connected as a single entity, and crossbeam physical dimension is determined according to root pile and anchor pole dimension synthesis, to ensure that stake-anchor pole forms composite construction, brings into play space and keeps off native effect.Root pile becomes two rows to be arranged in parallel, and front and back two campsheds are apart from getting 5～7 times of stake footpaths, and longitudinally pile center is apart from getting 1.0～1.2m.Result, according to landslide on-the-spot soil property and side slope physical dimension situation, is calculated in conjunction with landslide soil pressure in the long and stake footpath of the stake of root pile, adopts the long and stake footpath of piles with different according to root pile design specifications comprehensive Design, and the enough degree of depth of guarantee buried depth are to provide corresponding skid resistance.
Described root pile length is got 10～15m, root pile aperture 150mm～250mm.
Soil bolt length should be according to landslide soil property and landslide physical dimension, the comprehensive compound soil-baffling structure result of calculation of stake-beam-anchor pole, comprehensively determine with reference to soil bolt design specifications, to guarantee deeply sliding bed of anchor pole, enough bond stresss are provided, the every long 10～20m of anchor pole, aperture 100～150mm, the angle between inclination anchor pole and vertical root pile is 45 °.
The beneficial effects of the utility model are:
Root pile is as mini pile, and construction equipment is light, becomes hole dimension little, compares with general major diameter antislide pile, and easy construction, establishes a position flexible, little to soil layer disturbance, can avoid the secondary landslide causing due to construction;
Special secondary high-pressure slip-casting technology in root pile work progress, the stake Zhou Fuhe soil body forming through fracture grouting, can make pile body be anchored at reliably in the soil body and improve soil strength.Not only played the effect as antislide pile, and the compound soil body can more effectively improve landslide soil strength, thereby improve slope stability.
The vertical soil-baffling structure of double root pile and the combination of drawing anchor rod type soil-baffling structure, the more independent antislide pile of whole composite construction or the separately lateral stiffness of anchor pole significantly improve, and lateral deformation is little, and the supporting degree of depth and supporting scope all strengthen; When bearing landslide horizontal thrust, double root pile does the used time, by stake head piece, part sliding force is delivered to soil bolt, then is delivered in steady soil by soil bolt, structural entity stress condition is good, can give full play to the acting in conjunction of structure and the soil body, transfer the self-stable ability of the soil body.
