Description
Technical field
The present invention relates to a kind of anchorage holding pressure anchoring slight slope and construction method, a kind of holding type pressure slight slope anchor and construction method thereof.
Background technology
At present, slight slope carrys out bank protection frequently with methods such as soil nail wall, bar shotcrete with steel bar nets, stone-layings, owing to those methods all use the material such as reinforcing bar, cement concrete to form rigid structure to support fixing slight slope, and slight slope is graininess grogs consists of loose media, once acted on by water pressure, soil pressure, upper load, and rainwater, frost heave etc. corrode, the deformation such as the soil of slight slope still can loosen, saturated yielding, the protective slope structure of those rigidity cannot work in coordination with the deformation reinforcement slight slope of soil, often have impact on the effect of slight slope monolithic stability.
Summary of the invention
Deficiency for existing slight slope bank protecting method, the present invention proposes a kind of holding type pressure slight slope anchor and construction method thereof, use elastic anchor pole to implement precompressed and carry out reinforced soil slopes, it is the loosest that the soil particle making slight slope keeps bearing pressure, support from the inside configuration of slight slope soil and fix slight slope, improve slight slope resistance to overturning.
The present invention solves technical problem and adopts the following technical scheme that
A kind of holding type pressure slight slope anchor, include river levee, embankment or the slight slope of deep basal pit, described slight slope is disposed with quincuncial anchor point, it is mounted with anchor plate on each anchor point, in slight slope, the anchor hole vertical with slight slope face is got out by anchor plate centre bore, it is provided with an elastic anchor pole in each anchor plate and anchor hole, anchor pressing plate and nut have been respectively cooperating with it on the revealed section of elastic anchor pole, anchor pressing plate is faced out against slight slope and draws elastic anchor pole by fastening nut, until pricking to be lived by anchor in the soil bottom anchor hole by the inverted beard of elastic anchor pole inverted beard anchor head, flatten anchor pressing plate and prop up anchor plate, the elastic tube generation lengthening deformation of elastic anchor pole.
Described anchor plate is tubular rivet shape, and the backing plate of anchor plate is circular, and edge curves inwardly, and center has and the through hole of pillar uniform internal diameter, and the pillar of anchor plate is equal diameter pipe.
Described anchor pressing plate is vaulted " " shape, there is the panel seat of circle at anchor pressing plate center, there is round tube hole at the center of panel seat, radial several pieces pressing plates are equidistantly distributed on panel seat side, pressing plate in "～" shape, the width of pressing plate broadens by narrow from root to end, and the thickness of pressing plate is thinning by thickness from root to end, all has tie-rod to connect in the middle of adjacent two panels pressing plate.
Described elastic anchor pole is made up of with inverted beard anchor head bolt elastic tube, elastic tube is linked as through hole with the centre bore of inverted beard anchor head, described elastic tube is isodiametric pipe, screw thread is had outside the tube wall of slight slope face revealed section, hexagon brake hole is had inside tube wall, screw thread is had with inside the tube wall of inverted beard anchor head bolt section, staggered ellipse hole spaced apart is had on elastic tube interlude pipe shaft, and the long axis of ellipse hole and elastic anchor pole central axis, foam resin is all filled up in each ellipse hole, described inverted beard anchor head is cylindrical shape, several grooves being equally spaced along elastic anchor pole centerline direction are had on the lateral surface of inverted beard anchor head, both sides in every groove are respectively arranged with a fixing card, the inverted beard that a root is connected jointly is blocked with inverted beard anchor head bottom section by these two fixing cards.
The construction method of a kind of holding type pressure slight slope anchor, sequentially includes the following steps: successively
(1), after measuring the position of all anchor points on slight slope, the slight slope face boring of each anchor point disposes anchor plate；
(2) by the centre bore of anchor plate, in slight slope, the anchor hole vertical with slight slope face is got out；
(3) by the requirement of slight slope soil property Yu design length, select suitable inverted beard anchor head and elastic tube, after elastic tube is bolted into inverted beard anchor head elastic anchor pole, with instrument, fluted for inverted beard anchor head institute interior fixing chuck plate is broken, allow all inverted beards choose in the groove of inverted beard anchor head；
(4) elastic anchor pole inserts in the anchor hole of slight slope from anchor plate centre bore；
