The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of note of the anchor for soft-rock tunnel jacking of floor anchor cable, comprises anchor cable 1 and Grouting Pipe; Anchor cable 1 top movable is provided with anchor cable lock and anchor cable pallet; Anchor cable 1 is movably set in Grouting Pipe; Grouting Pipe is comprised of main Grouting Pipe 3 and segmenting slip casting pipe 4, is respectively equipped with plural slurry outlet 8 on the tube wall of main Grouting Pipe 3 and segmenting slip casting pipe 4; Main Grouting Pipe 3 one end that are positioned at segmenting slip casting pipe 4 tops are connected with segmenting slip casting pipe 4 movable whorls by sleeve 5, the cylindrical tube that sleeve 5 is hollow; Main Grouting Pipe 3 other ends are fixedly connected with Grouting Pipe pallet 6; Grouting Pipe pallet 6 belows are disposed with the stop grouting plug 7 being movably set on main Grouting Pipe 3 tube walls and are welded on the card of first on main Grouting Pipe 3 tube walls silk 11; Main Grouting Pipe 3 is flexibly connected with slip casting flexible pipe by Grouting Pipe connector 9, what Grouting Pipe connector 9 one end were hollow is cylindrical, be threaded with main Grouting Pipe 3, what Grouting Pipe connector 9 other ends were hollow is square, described both sides, end are provided with pin-and-hole 10, by U-shaped pin, are flexibly connected with slip casting flexible pipe; Anchor cable 1 bottom is movably set with lockset 2 and is welded on the card of second on lockset 2 silk 12.First card silk the 11 and second card silk 12 is for being bent into the reinforcing bar of certain angle, described respectively along the tube wall interval welding around of main Grouting Pipe 3 and lockset 2, be used for improving the anchoring property between main Grouting Pipe and anchor cable afterbody and drill hole wall, in case in slip casting process Grouting Pipe go out boring and during anchor cable pretension cable body be pulled out.
As shown in Figure 3,4, the cylindrical tube that main Grouting Pipe 3 and segmenting slip casting pipe 4 are hollow, on the tube wall of main Grouting Pipe 3 and segmenting slip casting pipe 4, be respectively equipped with two above slurry outlets 8, segmenting slip casting pipe 3 is connected to form by the cylindrical tube movable whorl of one section or one section above hollow, to adapt to deep hole grouting, reinforces anchor cable needs.
As shown in Figure 5, what Grouting Pipe connector 9 one end were hollow is cylindrical, be threaded with main Grouting Pipe 3, what Grouting Pipe connector 9 other ends were hollow is square, both sides, described end are provided with pin-and-hole 10, by U-shaped pin, be flexibly connected with slip casting flexible pipe, slip casting flexible pipe is flexibly connected the injection that realizes slurries with grouting pump.
Now in conjunction with Fig. 1,2,3,4,5, concrete using method of the present utility model is described:
(1) when install down-hole, subdrilling floor grouting hole;
(2) total length anchor cable 1 is installed in boring;
