Description
Technical field
The present invention relates to the design field of fixing instrument of constructing.
Background technology
In at present construction, usually adopt excavation type earth anchor, to imbed after earth anchor backfill again.This construction method destroys the soil property of sedendary soil, reduces mud soil classifiction; Also have a kind of existing earth anchor when being subject to the oblique pulling of anchor line, the direction with power rotates by drilling rod, is obliquely inserted into earth, makes soil layer loose, reduces load ability.
Summary of the invention
The object of the invention is for above problem, provides a kind of anti-oblique pull simple to operate, applied widely, that load ability is strong antitorque rotating group's anchor.
The present invention includes at least one press disc type earth anchor, at least one flange plate type earth anchor, connect respectively by same connecting plate between the top of each described press disc type earth anchor and the top of each flange plate type earth anchor, described press disc type earth anchor is successively set on the front end of connecting plate respectively along the length direction of connecting plate, described flange plate type earth anchor is successively set on the rear end of connecting plate respectively along the length direction of connecting plate; Each described press disc type earth anchor comprises the first ground anchor pole respectively, disjunctor is arranged on the first taper earth anchor point bottom the first ground anchor pole, be arranged on the spiral first ground anchors of the first ground anchor trend, be arranged at the first torsion ring of the first anchor pole upper end, ground; Be fixedly installed cross section in described first side, anchor pole top, ground for the platen of " L " shape, described cross section be the platen of " L " shape angle outwardly and one of them free end arrange straight down; Each described flange plate type earth anchor comprises the second ground anchor pole, disjunctor is arranged on the second taper earth anchor point bottom the second ground anchor pole, be arranged on the spiral second ground anchors of the second ground anchor trend, be arranged at the second torsion ring of the second anchor pole upper end, ground; The second ground anchor rod body between the second ground anchors and the second torsion ring arranges overhead gage, lower baffle plate, the second ground anchor pole between described overhead gage and lower baffle plate can slide up and down formula by pipe box wing plate is set.
Rod member of the present invention all adopts steel pipe as antitorque body, improves the Torsion Section modulus of the body of rod.When ensureing that weight is constant, greatly improve the anti-twisting property of rotating earth anchor.Wherein spiral fashion earth anchor with pressure is generally used for guy anchor, and bracing wire angle is generally about 45 °, and ground anchor pole is easily along stayguy direction bending.At anchor pole top, ground dress lastblock platen.When bracing wire imposes oblique pulling force to earth anchor, ground anchor pole is by the curved trend having side to fall, and pressing plate also falls for there is side, and upper plane earth blocks the rollover power of pressing plate opposing anchor pole, thus has resisted the horizontal component of bracing wire.Improve the antitorque anti-oblique pull ability of rotating ground anchor pole; Though the earth anchor with wing plate has rotating tendency under the effect of oblique pulling, wing plate prevents the rotation of drilling rod, keeps and expands original stressed stress cone, can bear larger anchor power.The earth anchor of spiral fashion earth anchor with pressure and band wing plate is linked to be an overall formation rotating earth anchor group by the present invention, earth ground has also been linked to be a larger soil property shearing stress cone, to resist the oblique pulling force of bracing wire, play the effect that 1+1 is greater than 2, be specially adapted to the soil property that other earth anchors such as rice terrace are difficult to be competent at.
Cross section of the present invention is the angle of the platen of " L " shape is 75 ~ 105 °.
The lower end of wing plate of the present invention is taper type.
Ground of the present invention anchor pole is hollow steel pipe, can improve the Torsion Section modulus of the body of rod.When ensureing that weight is constant, greatly improving the anti-twisting property of rotating earth anchor, the bending resistance of earth anchor is also increased to some extent.
