The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe in detail, but this embodiment should not be construed as the restriction to the utility model.
Referring to Fig. 1 to Fig. 2, the recyclable anchor cable of the utility model slip casting bag formula comprises slip casing by pressure pipe 1, anchor cable master muscle 2, slip casting bag 3, ends slurry cover 5, stack 10 and Grouting Pipe 11.
Slip casing by pressure pipe 1 is nonmetal Grouting Pipe, and in the present embodiment, slip casing by pressure pipe 1 is the hard PVC pipe.The front end of slip casing by pressure pipe 1 is provided with enclosed nonmetallic slip casting bag 3; Said slip casting bag 3 comprises front end-plate 6, elasticity external capsule 7 and end plate 8; Said front end-plate 6 is positioned at elasticity external capsule 7 with end plate 8 and is connected with the sealing of elasticity external capsule 7 front and back ends, and front end-plate 6 all is connected with 1 sealing of slip casing by pressure pipe with end plate 8.In optimum embodiment, front end-plate 6 is rigid plastics with end plate 8 and makes, and adopts thermal weld or extruding to connect between front end-plate 6, end plate 8 and the elasticity external capsule 7, and elasticity external capsule 7 should guarantee good sealing property; Slip casing by pressure pipe 1 adopts screw thread or Type of Welding to be connected with end plate 8 with front end-plate 6, and guarantees the sealing performance at interface position; Elasticity external capsule 7 employing rubber etc. have the material of favorable elasticity and expansiveness; Under the effect of certain grouting pressure, can expand gradually and become big; Ground forms the supporting body that termination as shown in Figure 2 enlarges around the extruding, simultaneously, and through parameters such as preset its shape, thickness; Can be so that carry out that slip casting bag 3 after the slip casing by pressure forms as Fig. 7 arrives shapes such as cylindrical, turbination shown in Figure 10, taper shape and spindle, thus the supporting capacity of the recyclable anchor cable of slip casting bag formula effectively increased.Present embodiment makes slip casting bag 3 external surfaces have certain roughness through some construction measures, to improve slip casting bag 3 outer walls and the frictional resistance between ground on every side.According to the setting time characteristic of duration length and slurries, select slurries type such as cement paste, cement mortar and water glass slurries etc. in the slip casting bag 3.When slip casting bag 3 is carried out slip casing by pressure, should be with grouting pressure, grouting amount as the control index, concrete numerical value can be confirmed through field trial.
Referring to Fig. 3, slip casing by pressure pipe 1 sidewall that is positioned at slip casting bag 3 is provided with injected hole 4, and said injected hole 4 outsides are enclosed with the nonmetallic slurry cover 5 that ends, and in the present embodiment, ends slurry cover 5 and ends the slurry cover for rubber.When with 1 slip casting of slip casing by pressure pipe, because slip casing by pressure pipe 1 is managed the interior bigger grouting pressure that exists, make slurries end slurry and overlap 5 that only producing the slit between slurry cover 5 and the slip casing by pressure pipe 1, slurries flow into slip casting bag 3 along the slit to external compression; After stopping slip casting, because slip casting bag 3 internal pressures are bigger, only slurry cover 5 is squeezed and is close to slip casing by pressure pipe 1, has stoped slurries in slip casing by pressure pipe 1 pipe, to reflux.
Referring to Fig. 1 to Fig. 2; Said anchor cable master muscle 2 is no cementability steel strand, and said no cementability steel strand are in the steel strand outside and wrap up one deck lubricant grease layer and one deck non-metallic layer successively, in the present embodiment; Said non-metallic layer can be a rubber layer, also can be plastic layer.Like this, being convenient to steel strand extracts out.Anchor cable master muscle 2 is vertically around slip casting bag 3 outsides.
Referring to Fig. 4 to Fig. 6, said front end-plate 6 is half-cylindrical, and its cylindrical surface is provided with groove 9 towards the front end of slip casing by pressure pipe 1 at front end-plate 6 half-cylindrical wall upper edge circumferencial directions, and anchor cable master muscle 2 is enclosed within on the groove 9.Groove 9 preferably equates with anchor cable master muscle 2 numbers.
Said stack 10 is a non-metallic pipe, communicates in stack 10 and the slip casting bag 3 and is connected with slip casting bag 3 sealings.In this city embodiment, stack 10 is the hard PVC pipe, and stack 10 adopts screw thread or Type of Welding to be connected with end plate 8, and guarantees the sealing performance at interface position.
Said Grouting Pipe 11 is for being located at the non-metallic pipe outside the slip casting bag 3, and Grouting Pipe 11 is to boring 12 other position slip castings except that slip casting bag 3, and in the present embodiment, Grouting Pipe 11 is the hard PVC pipe.For guaranteeing the position of slip casing by pressure pipe 1, anchor cable master muscle 2, stack 10 and Grouting Pipe 11, can be provided with the medium-height trestle (not shown) by 2～3m spacing, or other can guarantee the measure of slip casing by pressure pipe 1, anchor cable master muscle 2, stack 10 and Grouting Pipe 11 positions.
After the recyclable anchor cable of the described slip casting bag formula of the utility model treats that the slurries maintenance in the slip casting bag 3 reaches design strength; Can carry out 2 stretch-draw of prestress anchorage cable master muscle; Anchor platform 13 is set; And with ground tackle 14 anchoring anchor cable master muscle 2, the type of anchor platform 13 and ground tackle 14 can be identical with common anchor cable, but should be convenient to the installation and removal of ground tackle 14.
The concrete realization of the utility model can be made up of following steps:
(1) in rock soil medium, offers boring 12.
(2) with the recyclable anchor cable of slip casting bag formula connect on request closely, colligation is firm, and anchor cable master muscle 2 vertically around slip casting bag 3 outsides and be enclosed within on the groove 9 of front end-plate 6, slowly is positioned in the boring 12 then, makes slip casting bag 3 be positioned at the bottom of boring 12.
(3) through slip casing by pressure pipe 1 slowly slip casting in slip casting bag 3, after stack 10 has stable slurries to flow out, stack 10 mouths of pipe are blocked; Increase grouting pressure gradually, carry out slip casing by pressure, after grouting pressure and grouting amount reach designing requirement, 1 sealing of slip casing by pressure pipe.
(4), carry out slip casting to other positions of boring 12 through Grouting Pipe 11.
(5) after slurries solidified and reach design strength, stretch-draw prestressing force anchor cable master muscle 2 promptly formed by " the recyclable anchor cable of slip casting bag formula ".
(6) possess anchor cable master muscle 2 dismounting conditions after, discharge prestressing force, extract the recycling that non-bending steel cable can be realized anchor cable master muscle 2 out.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
The content of not doing in this manual to describe in detail belongs to this area professional and technical personnel's known prior art.
