Above-mentioned seal is a sealant tape; The steel strand surface that the utility model is positioned at described free section is provided with corrosion-inhibiting coating, is with protection tube outside being provided with the steel strand of corrosion-inhibiting coating, and seize with described seal shutoff in the gap between this protection tube lower port and the described steel strand; Described grout pipe is positioned at the center of whole anchor cable; Described shading ring center is provided with circular opening, and described grout pipe penetrates from the anchor cable end, through guide head behind free section, seal, shading ring central circular hole.
The utility model is owing to the cantilever segment at described pile body is provided with prestress anchorage cable, the lower end of this prestress anchorage cable is anchored in the following good ground of described slide plane, the upper end is connected with the cantilever segment of described pile body, and with the described pile body θ that has angle, like this, the thrust that the oblique pulling of build-in force in the good ground at the bottom of just can relying on below slide plane and stake top prestress anchorage cable comes the balance landslide, fundamentally changed the irrational stress of existing cantilevered antislide pile, make it to become the upper end elastomeric bearing, the freely-supported shape stress of lower end elastic embedding, thereby reduced the internal force of pile body, the cross sectional dimensions of pile body, the building-in depth of stake, reduce the reinforcing bar and the concrete consumption of pile body, fundamentally reduced the construction costs of landslide control; Simultaneously, also strengthened the pile body anti-slide performance widely.When the thrust that comes down is big, a plurality of anchor cable preformed holes and prestress anchorage cable correspondingly can be set at the cantilever segment of described pile body.
The prestress anchorage cable that the utility model adopted is an once grouting moulding prestress anchorage cable, make original back-grouting be reduced to once grouting, ensured the compactness of free section grouting, guaranteed anchoring quality, made its pile body that bigger oblique pulling is provided to antislide pile.
To sum up, the utility model construction costs is low, anti-slide performance is strong, is specially adapted to field landslide disaster training workses such as highway, railway, water conservancy and hydropower building, urban architecture.
