Abstract
The invention discloses a kind of band skeleton and expand body anchor cable, it includes Grouting Pipe, head protector, clip, anchor cable and anchor cable guide pipe, front band in Grouting Pipe is mounted below a steel cylinder, the circumferential wall of steel cylinder is provided with downwards a sandwich passage, Grouting Pipe is mounted below a three-way pipe communicated with sandwich passage in front band, the ring piston that one first half cooperates with sandwich passage is installed below steel cylinder, lower end peripheral at piston is rotatably connected to guide-localization frame on corresponding with eight uniform bearing pins to side-lower respectively, one retainer ring is installed between slip casting check 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 it is connected between lower guide-localization frame.The present invention can make withdrawal resistance significantly promote, and the withdrawal resistance after anchoring can reach between 600～1200KN, is applicable not only to husky ovum stratum, is also applied for clay stratum.
Description
Technical field
The present invention is that a kind of band skeleton being applicable to use during large-scale construction engineering foundation stabilization expands body anchor cable.
Background technology
Existing expansion body anchor cable has multiple, their basic structure is to be provided with a location head protector at the front end clip of a Grouting Pipe, it is 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 the most corresponding through hole, a guide pipe it is respectively fixed with in the through hole of each upper and lower correspondence, an anchor cable has been respectively penetrated in each guide pipe, the lower end of each anchor cable is connected in head protector on the platen at injected hole, 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 body anchor cable structure that expands has bigger resistance to plucking dynamics, it is widely used at present, but has the drawback that its withdrawal resistance only has 250～600KN, it is impossible to adapt to the needs that more large pulling resistance degree engineering foundation is reinforced.
Summary of the invention
It is an object of the invention to provide a kind of withdrawal resistance that adapts to and expand body anchor cable more than the band skeleton of 600KN needs.
nullThe technical scheme is that and complete 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: the front band in Grouting Pipe is mounted below a steel cylinder，The circumferential wall of steel cylinder is provided with downwards a sandwich passage，Grouting Pipe is mounted below a three-way pipe communicated with sandwich passage in front band，The ring piston that one first half cooperates with sandwich passage is installed below steel cylinder，Lower end peripheral at piston is rotatably connected to guide-localization frame on corresponding with eight uniform bearing pins to side-lower respectively，One retainer ring is installed between slip casting check 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 it is connected between lower guide-localization frame.It is provided with one in Grouting Pipe between lower catch hoop with pistons stops and the aqueous vapor that each expanding bar and guide-localization mount in the inner is separated pouch.
The present invention is through above-mentioned improvement, compared with prior art, not only remains its advantage, withdrawal resistance also can be made significantly to promote, and the withdrawal resistance after anchoring can reach between 600～1200KN, is applicable not only to husky ovum stratum, is also applied for clay stratum.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention；Fig. 2 is the present invention structural representation 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 present invention structural representation when being provided with pouch.
Detailed description of the invention:
nullEmbodiment is described in detail in conjunction with accompanying drawing，It includes Grouting Pipe 1、Head protector 11、Clip 10、Anchor cable 2 and anchor cable guide pipe 14，Front band in Grouting Pipe is mounted below a steel cylinder 4，The circumferential wall of steel cylinder is provided with downwards a sandwich passage，Grouting Pipe is mounted below a three-way pipe communicated with sandwich passage 3 in front band，The ring piston 5 that one first half cooperates with sandwich passage 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 on corresponding to side-lower，One retainer ring 12 is installed between slip casting check 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 it is connected between lower guide-localization frame.It is provided with one in Grouting Pipe between lower catch hoop with pistons stops each expanding bar and guide-localization are mounted aqueous vapor in the inner to separate pouch 8.By the utility model by holing in feeding stratum during use, connect Grouting Pipe, first pass through in the sandwich passage that high pressure slurries are advanced copper cylinder by threeway, piston is forced to move downward, being 90 extrapolated shapings each upper and lower guide-localization frame, after slip casting reaches certain pressure, slip casting check valve is opened, start slip casting in expanding body cavity or pouch, till filling.A kind of standardized anchoring body can be become after solidification.The expanding bar promoted by piston is used to carry out expanding, ensure that the standardization of anchoring enlarged body shape, the withdrawal resistance expanding anchoring body being consequently formed is greatly improved the most therewith, it is not added with during pouch being applicable to husky ovum stratum, added with the clay stratum that is applicable to of pouch, withdrawal 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: the front band in Grouting Pipe is mounted below a steel cylinder, the circumferential wall of steel cylinder is provided with downwards a sandwich passage, Grouting Pipe is mounted below a three-way pipe communicated with sandwich passage in front band, the ring piston that one first half cooperates with sandwich passage is installed below steel cylinder, lower end peripheral at piston is rotatably connected to guide-localization frame on corresponding with eight uniform bearing pins to side-lower respectively, one retainer ring is installed between slip casting check 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 it is connected between lower guide-localization frame.
