Description
Technical field
The utility model relates to a kind of ground tackle and the job practices thereof of pressing the anchoring slight slope, a kind of holding type pressure slight slope anchor specifically held.
Background technology
At present, slight slope often adopts methods such as soil nailing wall, bar shotcrete with steel bar nets, stone-laying to come bank protection, because all adopting materials such as reinforcing bar, cement concrete to form rigid structures, those methods come the support fixation slight slope, and being the graininess grogs, slight slope consists of loose media, in case the effect of the water pressure of being subjected to, soil pressure, upper load, and erosion such as rainwater, frost heave, distortion such as the soil of slight slope still can become flexible, saturated yielding, the protective slope structure of those rigidity can't be worked in coordination with the distortion reinforced soil slopes of soil, has often influenced the effect of slight slope monolithic stability.
The utility model content
Deficiency at existing slight slope bank protecting method, the utility model proposes a kind of holding type pressure slight slope anchor, adopt the elasticity anchor pole to implement precompressed and come reinforced soil slopes, it is not loose to make the soil particle of slight slope keep bearing pressure, support and fixing slight slope from the inside configuration of slight slope soil, improved the slight slope resistance to overturning.
The utility model technical solution problem adopts following technical scheme:
A kind of holding type pressure slight slope anchor, comprised river levee, the slight slope of embankment or deep foundation ditch, be furnished with quincuncial anchor point at described slight slope, be mounted with anchor plate on each anchor point, in slight slope, get out the anchor hole vertical with the slight slope face by the anchor plate centre bore, be provided with an elasticity anchor pole in each anchor plate and the anchor hole, be combined with anchor pressing plate and nut on the revealed section of elasticity anchor pole respectively, fastening nut is pulled outwardly the elasticity anchor pole with the anchor pressing plate against the slight slope face, until the elasticity anchor pole being fallen falling of anchor head must pricking in the soil of anchor hole bottom to be lived by anchor, flatten the anchor pressing plate and prop up anchor plate, the elastic tube generation lengthening deformation of elasticity anchor pole.
Described anchor plate is the tubular rivet shape, and the backing plate of anchor plate is circular, and edge curves inwardly, and there is the through hole with the pillar uniform internal diameter at the center, and the pillar of anchor plate is the equal diameter pipe.
Described anchor pressing plate is vaulted " " shape, there is circular panel seat at anchor pressing plate center, there is round tube hole at the center of panel seat, equidistantly be distributed with radial several pieces pressing plates on the panel seat side, pressing plate is "～" shape, the width of pressing plate is broadened by narrow to the end from root, the thickness of pressing plate from root to the end by thick attenuation, all have tie-rod to connect in the middle of adjacent two pressing plates.
Described elasticity anchor pole is made of elastic tube and the palpus anchor head bolt that falls, elastic tube with fall must anchor head centre bore be linked as through hole, described elastic tube is isodiametric pipe, there is screw thread in the tube wall outside at slight slope face revealed section, there is the hexagon brake hole tube wall inboard, with fall must anchor head bolt section the tube wall inboard screw thread is arranged, staggered ellipse hole spaced apart is arranged on the elastic tube interlude pipe shaft, and the long axis of ellipse hole is vertical with elasticity anchor pole center line, all fill up foam resin in each ellipse hole, described must anchor head be cylindrical shape, fall several grooves that have suitable elasticity anchor pole centerline direction to be equally spaced on must the lateral surface of anchor head, there is a fixing card both sides in every groove, by these two fixedly card block a root jointly and fall the palpus that must anchor head bottom section be connected.
Holding type pressure slight slope anchorage in the utility model is in following operating principle: be subjected to the effect of loads such as water pressure, soil pressure, vehicle etc., and sleet, freezing erosion, unstability situations such as slippage can take place in the slight slope of river levee, embankment, foundation ditch etc., the utility model is little according to adhesion stress between the crumb structure of soil, particle, easy characteristic such as loose, quincuncial arrangement is set and the elasticity anchor pole of certain-length is arranged at slight slope, utilize the elastical retraction power of elasticity anchor pole and anchor pressing plate, make whole slight slope be in pressured state all the time and can not become flexible, improved the resistance to overturning of slight slope.Staggered elliptical hole spaced apart is set on the described elasticity anchor pole elastic tube pipe shaft, has elasticity, rigidity and intensity preferably, again the elasticity anchor pole fall must anchor head to be provided with down must, open must be under the pulling of elastic tube, can prick automatically in the soil bottom the anchor hole becomes anchor head.When turning nut when being pulled outwardly the dynamic elasticity anchor pole, with elasticity anchor pole elastic tube generation lengthening deformation, the retraction force by the elliptical hole of elasticity anchor pole elastic tube produces makes the soil of the slight slope that anchor is lived keep bearing pressure.By the force analysis of elasticity anchor pole, the stiffness factor of elasticity anchor pole elastic tube is K, and the elongation of elastic tube is Δ, and then the retraction force of elastic tube is the P=K Δ; The frictional resistance of elastic tube and anchor hole border soil is F, and the bounce that the anchor pressing plate is crushed is W, and the pressure that acts on slight slope soil is N, and slight slope soil average area by compression is S.According to force system in equilibrium: P=F+W+NS, then: pressure N:N=(P-F-W)/S=that slight slope soil bears (the K Δ-F-W)/S.Because P＞F+W, so the pressure that the maintenance of slight slope soil is born.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model proposes a kind of holding type pressure slight slope anchor, be the characteristic of bulk materials according to soil, utilize anchor pressing plate, anchor plate and elasticity anchor pole to form the structure that can bounce back, soil to slight slope applies precompression, the soil particle that makes slight slope keeps bearing pressure and not loose, support and fixing slight slope from the inside configuration of slight slope soil, improved the resistance to overturning of slight slope.Having characteristics such as the slight slope, easy construction, the cost that adapt to different soil properties are low, repeated use, life-span length, is a kind of new-type slight slope reinforced ground tackle and job practices.
