Abstract
The invention discloses an anchor cable anchor cable with a framework expanding body. The anchor cable comprises a grouting pipe, a head guard, an upper clamp, a lower clamp, anchor cable parts and an anchor cable guide pipe, wherein a steel cylinder is mounted at the lower surface of the upper clamp of the grouting pipe; an interlayer channel is formed downwards in the periphery wall of the steel cylinder; a three-way pipe communicated with the interlayer channel is mounted on the grouting pipe and at the lower surface of the upper clamp; a cylindrical piston of which the upper half part is mutually matched with the interlayer channel is mounted below the steel cylinder; upper guide positioning racks are correspondingly and rotationally connected with eight uniformly distributed pin shafts towards the lower sides, at the periphery of the lower end of the piston; a fixed ring is mounted between a grouting one-way valve and the lower clamp; eight uniformly distributed lower guide positioning racks are mounted on the fixed ring with the pin shafts respectively; and an expanding rod is connected between every two corresponding upper guide positioning rack and lower guide positioning rack. With the adoption of the anchor cable, the pulling resistance can be improved greatly; the pulling resistance can reach 600-1200KN after anchorage; and the anchor cable is applicable to both sand-gravel stratums and clay stratums.
Description
Technical field:
The present invention is that a kind of band skeleton used when being applicable to large-scale construction engineering ground stabilization expands body anchor cable.
Background technology:
Existing expansion body anchor cable has multiple, their basic structure is provided with a location head protector at the front end clip of a Grouting Pipe, be fixed with an anchor cable in the rear end of Grouting Pipe and clip is installed, the peripheral wall of each clip is respectively equipped with through hole corresponding up and down, a guide pipe is fixed with respectively in the through hole of each upper and lower correspondence, an anchor cable has been penetrated respectively in each guide pipe, the lower end of each anchor cable is connected on the platen at injected hole place in head protector, the upper end of each anchor cable is drawn respectively in the guide pipe of top, in order to increase resistance to plucking dynamics, Grouting Pipe is fixed with at least one by crimp and expands somatocyst bag.Though this traditional expansion body anchor cable structure has larger resistance to plucking dynamics, be widely used at present, the shortcoming existed is that its uplift resistance only has 250 ~ 600KN, can not adapt to the needs that more large pulling resistance degree engineering foundation is reinforced.
Summary of the invention:
The object of this invention is to provide a kind of band skeleton expansion body anchor cable that can adapt to uplift resistance and be greater than 600KN needs.
Technical scheme of the present invention completes as follows, a kind of band skeleton expands body anchor cable, it includes Grouting Pipe, head protector, clip, anchor cable and anchor cable guide pipe, it is characterized in that: a steel cylinder is installed below the clip of Grouting Pipe, the circumferential wall of steel cylinder is provided with downwards a sandwich passage, Grouting Pipe is provided with a tee piece communicated with sandwich passage below front band, the ring piston that a first half and sandwich passage cooperatively interact is installed below steel cylinder, the bearing pin uniform with eight respectively at the lower end peripheral of piston is rotatably connected to guide-localization frame accordingly to side-lower, a retainer ring is installed between slip casting one way valve and lower catch hoop, retainer ring is provided with eight uniform lower guide-localization framves with bearing pin respectively, upper in each correspondence, an expanding bar is connected between lower guide-localization frame.Grouting Pipe between lower catch hoop with pistons stops is provided with one and the aqueous vapor that each expanding bar and guide-localization mount in the inner is separated pouch.
The present invention, through above-mentioned improvement, compared with prior art, not only remains its advantage, and uplift resistance also can be made significantly to promote, and the uplift resistance after anchoring can reach between 600 ~ 1200KN, is not only applicable to husky ovum stratum, is also applicable to clay stratum.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention; Fig. 2 is the structural representation of the present invention when expanding frame opens; Fig. 3 is the A-A sectional view of Fig. 1; Fig. 4 is the B-B sectional view of Fig. 1; Fig. 5 is the structural representation of the present invention when being provided with pouch.
Detailed description of the invention:
Describe embodiment in detail by reference to the accompanying drawings, it includes Grouting Pipe 1, head protector 11, clip 10, anchor cable 2 and anchor cable guide pipe 14, a steel cylinder 4 is installed below the clip of Grouting Pipe, the circumferential wall of steel cylinder is provided with downwards a sandwich passage, Grouting Pipe is provided with a tee piece communicated with sandwich passage 3 below front band, the ring piston 5 that a first half and sandwich passage cooperatively interact is installed below steel cylinder, the bearing pin 6 uniform with eight respectively at the lower end peripheral of piston is rotatably connected to guide-localization frame 7 accordingly to side-lower, a retainer ring 12 is installed between slip casting one way valve 9 and lower catch hoop, retainer ring is provided with eight uniform lower guide-localization framves 13 with bearing pin respectively, upper in each correspondence, an expanding bar 15 is connected between lower guide-localization frame.Grouting Pipe between lower catch hoop with pistons stops is provided with one and each expanding bar is separated pouch 8 with the guide-localization aqueous vapor mounted in the inner.During use, the present invention is sent in stratum by holing, connect Grouting Pipe, first by threeway, high pressure slurries are advanced in the sandwich passage of copper cylinder, piston is forced to move downward, be that 90o is extrapolated shaping each upper and lower guide-localization frame, after slip casting reaches certain pressure, slip casting one-way valve opens, start slip casting in expansion body cavity or pouch, till filling.A kind of standardized anchoring body can be become after solidifying.The expanding bar promoted by piston is adopted to carry out expanding, ensure that the standardization of anchoring enlarged body shape, the uplift resistance of the expansion anchoring body formed thus is also greatly improved thereupon, husky ovum stratum is applicable to when not adding pouch, what be added with pouch is applicable to clay stratum, and uplift resistance is between 600 ~ 1200KN.
Claims (2)
1. a band skeleton expands body anchor cable, it includes Grouting Pipe, head protector, clip, anchor cable and anchor cable guide pipe, it is characterized in that: a steel cylinder is installed below the clip of Grouting Pipe, the circumferential wall of steel cylinder is provided with downwards a sandwich passage, Grouting Pipe is provided with a tee piece communicated with sandwich passage below front band, the ring piston that a first half and sandwich passage cooperatively interact is installed below steel cylinder, the bearing pin uniform with eight respectively at the lower end peripheral of piston is rotatably connected to guide-localization frame accordingly to side-lower, a retainer ring is installed between slip casting one way valve and lower catch hoop, retainer ring is provided with eight uniform lower guide-localization framves with bearing pin respectively, upper in each correspondence, an expanding bar is connected between lower guide-localization frame.
