Abstract
The utility model discloses an unbonded prestressed anchor cable grouting cap. A cap body of the grouting cap is of a hollow cylinder with an opening at one end, a grouting hole penetrating through a grouting pipe is arranged on the end surface at the sealed end of the cap body, an exhaust pipe is arranged in the position, which is close to the sealed end of the cap body, on the body wall of the cap body, and a valve is arranged on the exhaust pipe. When the unbonded prestressed anchor cable grouting cap is applied, the open end of the grouting cap disclosed by the utility model is mounted on a steel padding plate, when grouting is started, the valve is opened, and when grout flows out of the pipe orifice of the exhaust pipe, the valve is closed, and high pressure is kept for continuing grouting so as to enable an anchor cable hole to perform circulating grouting under the design pressure till the design requirements are achieved; and after the end of grouting, the grouting cap is further dismantled after the grout is solidified. The unbonded prestressed anchor cable grouting cap disclosed by the utility model can be used for enabling the grouting in the anchor cable hole to be saturated, reducing the waste of the grout, eliminating the need of secondary grout supplement construction, effectively reducing engineering cost and realizing long-term repeated use.
Description
Technical field
The utility model relates to a kind of binding prestress anchor cable slip casting auxiliary equipment, relates in particular to a kind ofly can make the full non-bonding prestress tendon slip casting cap of slip casting in the anchor cable hole.
Background technology
Non-bonding prestress tendon is often used in the slope retaining construction; Non-bonding prestress tendon is exactly to adopt the steel strand that have sheath to be compiled into the anchor cable bundle according to designing requirement, and the anchor cable bundle is put into boring, first grout injection; Make steel strand and country rock form an integral body through the perfusion neat slurry; But neat slurry has shrinkage, and cavity can appear in the aperture behind the certain hour, generally after anchorage cable stretching is accomplished, carries out second pulp feeding.The second pulp feeding construction, the slurries waste is many, and the grouting plumpness also can't guarantee.
Summary of the invention
The purpose of the utility model just is that providing a kind of in order to address the above problem can make the full non-bonding prestress tendon slip casting cap of slip casting in the anchor cable hole.
The utility model is realized above-mentioned purpose through following technical scheme:
The cap body of the said slip casting cap of the utility model is the hollow circular cylinder of an end opening; The end face that said cap body seals an end is provided with the injected hole that is used to pass grout pipe; The position of sealing an end near said cap body on the said cap body body wall is provided with stack, and said stack is provided with valve.
Further, said cap body opening one end stretches out and forms the cap seat, and said cap seat is provided with installing hole.
During application; The utility model is installed on the billet through installing hole, and beginning is opened valve during slip casting, treats slurries valve-off when the stack mouth of pipe flows out; Keep high pressure to continue slip casting, make the anchor cable hole under design pressure, carry out cycle grouting until reaching designing requirement; Removing the slip casting cap again after grouting finishes to wait to coagulate gets final product.
Particularly, said injected hole is two and is symmetricly set in said cap body and seals on the end face of an end.
Said installing hole is four and evenly is arranged on the circumference of said cap seat.
The beneficial effect of the utility model is:
The utility model can make in the anchor cable hole slip casting full and reduced the slurries waste, does not need the second pulp feeding construction, has reduced engineering cost effectively; The utility model processing is simple, easy to use, and can reuse for a long time, and cost is low.

Fig. 3 is the main TV structure sketch map in the use of the utility model non-bonding prestress tendon slip casting cap;
Fig. 4 is that the structure for amplifying sketch map is looked on the right side in the use of the utility model non-bonding prestress tendon slip casting cap.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As depicted in figs. 1 and 2; The cap body 7 of the utility model non-bonding prestress tendon slip casting cap is the hollow circular cylinder of an end opening; The end face that cap body 7 seals an end is provided with the injected hole 12 that is used to pass grout pipe; The position of sealing an end near cap body 7 on the body wall of cap body 7 is provided with stack 8, and stack 8 is provided with valve 9; One end of cap body 7 openings stretches out and forms cap seat 11, and cap seat 11 is provided with installing hole 13.
As depicted in figs. 1 and 2, injected hole 12 is two and is symmetricly set in cap body 7 and seals on the end face of an end; Installing hole 13 is four and evenly is arranged on the circumference of cap seat 11.
Like Fig. 3 and shown in Figure 4, during application, the injected hole 12 of the utility model, stack 8, valve 9, cap seat 11, installing hole 13 and cap body 7 are processed into an integral body in advance, are installed on the billet 3 through installing hole 13.Billet 3 is installed on the anchor pier 2.Before the utility model is installed; Screw rod 5 is welded on the billet 3 according to the position that designs in advance, and cap body 7 is placed on the billet 3, and screw rod 5 passes through 4 installing holes 13 of cap body 7; Increase one deck rubber washer 15 between cap body 7 and the billet 3; Through nut 4 cap body 7 and billet 3 are fixed then, two Grouting Pipe 10 of anchor cable bundle 6 pass through two injected holes 12 respectively, and Grouting Pipe 10 is connected on the grouting equipment and seals.Open valve 9 during beginning slip casting, when treating that slurries begin to flow out in stack 8, valve-off 9 makes anchor cable hole 1 under design pressure, carry out cycle grouting until reaching designing requirement, so promptly reaches the full problem of slip casting in the hole.Removing the utility model again after grouting finishes to wait to coagulate gets final product.
