Further, described anchor device comprises pressure-bearing steel plate, flat anchor and fixation steel plate, flat anchor clamp is connected between the two by fixation steel plate and pressure-bearing steel plate, one end and the fixation steel plate of flat anchor are fixed, the other end is vertically connected in pressure-bearing steel plate, and the existence of fixation steel plate avoids occurring during lower anchor cable the situation that intermediate plate gets loose, and flat anchor is longitudinally provided with ground tackle hole, this ground tackle hole is used for through the anchor cable body of rod, and adopts intermediate plate to lock.Same, fixation steel plate and pressure-bearing steel plate are provided with the hole passed for the anchor cable body of rod.So just anchor device is fixed on the anchor cable body of rod.
Again further, described anchor cable body of rod stream line comprises without parcel steel strand and non-bending steel cable.
In addition, described anchor cable rod end is also provided with guiding cap.Guiding cap front end is provided with tip portion, is convenient to of the present utility model laying.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model adopts the slip casting of calabash shaped canvas bag to form the alternate electric hoist structure of thickness, and thin portion structure plays good supporting role to the anchor cable body of rod, makes the anchor cable body of rod placed in the middle, does not occur eccentric phenomena.The pressure of end disperses by the alternate electric hoist structure of thickness, and stress is concentrated and produces moderate finite deformation to avoid end to occur.Adopt this structure to make pressure dissipation, make enlarged footing part uniform force, avoid occurring cracking because of stress raisers.
(2) the utility model anchor device adopts flat anchor+pressure-bearing steel plate, and welding edges fixation steel plate can ensure anchoring effect, occurs that intermediate plate gets loose situation when avoiding again producing lower anchor cable.
(3) the utility model total is based on pressurized, gives full play to the bearing capacity of the end soil body, and the loss of prestress of anchor cable later stage is very little, effectively in support system Deformation control.
(4) the utility model make and use cost lower, can increase substantially anchor cable bearing capacity, economic benefit is obvious, easy to utilize.
