Description

A kind of flat pressure dispersing anchorage cable wall retaining structure of rock matter cut slope
Technical field
The invention belongs to Geotechnical Engineering field, and in particular to a kind of flat pressure dispersing type anchor of rock matter cut slope Rope wall retaining structure.
Background technology
It is existing for more than In A Crushed Rock cut slope using structures such as retaining wall, friction pile and anchored pile, prestress anchorage cables Supporting and retaining system protection is carried out with reference to classification slope.For In A Crushed Rock Slope, wall height is usually no more than 10m, and friction pile is no more than 12m, anchored pile is no more than 14m, and top classification slope excavated volume is big, it is more to take up an area, particularly when side slope top is close to existing structure Thing is built, slope excavating is limited, it is necessary to do particular design when retaining wall, friction pile and anchored pile combination classification slope can not be implemented, Construction is complicated.
The content of the invention
The purpose of the present invention is exactly that the deficiency existed to solve above-mentioned background technology is put down there is provided a kind of rock matter cut slope Platen pressure dispersed anchor cable wall retaining structure.
The technical solution adopted by the present invention is:A kind of flat pressure dispersing anchorage cable wall supporting and retaining system knot of rock matter cut slope Many scattered pressure anchor wires of insertion, the Slope body surface in structure, including one or more levels side slope slopes, the Slope body Steel concrete plate is laid in face, and the part on the scattered pressure anchor wire end protrusion steel concrete plate surface, which passes through, mixes Solidifying grave closes to form concrete enclosing anchor head.
Further, the steel concrete plate thickness is 0.3-0.5m.
Further, be arranged at intervals multiple spilled water holes on the steel concrete plate, multiple spilled water holes go to upper and lower, it is left, Right interlaced arrangement, the water inlet of spilled water hole is wrapped up using permeable geotextiles.
Further, expansion joint is set between adjacent reinforced concrete flat board, stretch slit width 0.02m, filling in expansion joint Deep 0.2m pitch hemp cut.
Further, the steel concrete plate bottom embedment below ground, length of embedment is more than or equal to 1m.
Further, the angle between the scattered pressure anchor wire and horizontal plane is 15-20 °.
Further, the length of the scattered pressure anchor wire is 15-50m.
Further, every grade of side slope slopes bottom sets concrete platform, and concrete platform width is more than or equal to 3m.
Further, every grade of side slope slopes are highly 10-20m.
Further, the ratio of slope of the side slope slopes is 1:0.2-1:0.5.
The present invention is combined with pressure dispersing anchorage cable using steel concrete plate and detritus matter cut slope wall is carried out Supporting file is protected, and solves In A Crushed Rock cut slope resistance to overturning and control slope excavating width, the skill for reducing earth clearance Art problem, the influence to existing buildings can be also reduced to greatest extent.Pressure dispersing anchorage cable structure has certain flexibility, energy Side slope slight deformation is enough adapted to, and anti-seismic performance is good;The height of steel concrete plate wall can be adjusted according to field condition, be fitted Should be able to power it is strong;Retaining structure construction is simple, conveniently, good integrity, save take up an area, it is handsome in appearance, and structure has certain flexibility, The common stress of coordination of rock matter cut slope and the stable safety of side slope are ensure that, can be widely popularized in roads such as railway, highways In moat slope construction operation.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the schematic cross-section of steel concrete plate of the present invention.
In figure:1- side slope slopes;2- disperses pressure anchor wire;3- steel concrete plates;4- concrete enclosing anchor heads;5- Spilled water hole;6- concrete platforms;7- strengthens arrangement of reinforcement.
Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, is easy to that this hair is well understood It is bright, but they do not constitute restriction to the present invention.
As shown in Figure 1 and Figure 2, the present invention includes many points of insertion in one or more levels side slope slopes 1, the side slope slopes 1 Pressure anchor wire 2 is dissipated, steel concrete plate 3 is laid on the surface of side slope slopes 1.The ratio of slope of side slope slopes 1 is 1:0.2-1: 0.5, every grade of bottom of side slope slopes 1 sets concrete platform 6, and the width L of concrete platform 6 is more than or equal to 3m.Every grade of side slope slopes 1 Highly it is 10-20m, slope height can be adjusted according to orographic condition.
In such scheme, the part on the scattered end of pressure anchor wire 2 protrusion steel concrete plate 3 surface passes through concrete Closing forms concrete enclosing anchor head 4.Scattered angle α between pressure anchor wire 2 and horizontal plane is 15-20 °, disperses pressure-type The length of anchor cable 2 is calculated and determined according to side slope sliding force or soil pressure inspection, generally 15-50m, and slip casting is once to note in anchor cable hole Slurry, slurry processes are returned using bottom hole, irrigate M35 cement mortar.
In such scheme, the thickness of steel concrete plate 3 is 0.3-0.5m, after its interior colligation of reinforcing bar 3.2 is good, general to use It is not less than C35 concrete casts in situs.Require to strengthen arrangement of reinforcement 7 in the position of pressure dispersing anchorage cable 2 in steel concrete plate 3. Set in expansion joint (not shown), flexible slit width 0.02m, expansion joint and clogged deeply between adjacent reinforced concrete flat board 3 0.2m pitch hemp cut.Below, length of embedment H is big for the bottom 3.1 of steel concrete plate 3 embedment ground (i.e. concrete platform 6) In equal to 1m.Steel concrete plate 3 is arranged at intervals multiple diameter 0.1m pvc pipe spilled water hole 5 from more than ground every 2.0m, Multiple spilled water holes 5 are gone to upper and lower, left and right interlaced arrangement, and the water inlet of spilled water hole is wrapped up using permeable geotextiles.
Cut slope as it is point multistage when, the pressure dispersing anchorage cable for the upper level side slope that should first construct, pour and be poured in reinforced concrete Native flat board, treats that upper slope is all constructed after the completion of construction the pressure dispersing anchorage cable and steel concrete plate of next stage again, Excavate one-level, reinforcement protection one-level.
Steel concrete plate can coordinate group anchor (anchor) structure as a kind of rigid structure, by pressure dispersing anchorage cable Prestressing force more Transmit evenly makes the overall stress of side slope, improves the resistance to overturning and pressure dispersing type of side slope to domatic The compatibility of deformation ability of anchor cable side slope.
The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
