Described coupler is provided with one way valve.
Described extension is aluminum material, is carved with cannelure above.
Described needle point is steel material, and front end is coniform or trapezoidal shape.
The restorative procedure that adopts the above-mentioned equipment of repairing for in-service concurrent minute crack grouting, specifically comprises:
(1) pour into repair liquid, repair liquid is injected to the cartridge of high pressure manual grout pump;
(2) cutter injected hole, the rower of going forward side by side shows;
(3) filling cracks: Water slop injector is inserted to the injected hole indicating, press action bars, and note observing manometric reading in slip casting process, make slurries evenly inject crack and can not destroy fissured structure, until repair sheets plane surpasses inlet height.
In described step (2), concrete grammar is: first with chisel or electric drill, from the upper end in crack, to ，Yan crack, lower end, every 200～300mm, with chisel, digging out diameter is 10mm, the injected hole of the degree of depth 10～20mm; With wire brush, near the weathered layer of concrete surface crack is removed, then removed the floating ash on injected hole and surface with hairbrush and ear washing bulb, with adhesive tape, seal the crack between each injected hole and injected hole;
The concrete steps of described step (3) are:
(i) indicate injected hole to be mended a split: the crack that selection will be repaired, to wanting the injected hole of slip casting to indicate;
(ii) carry out slip casting; Water slop injector is inserted to the injected hole indicating, when crack is that tilt or vertical, injection should be from the injected hole of minimum point, carry out slip casting, in slip casting process, note observing manometric reading, make slurries evenly inject crack and can not destroy fissured structure, until repair sheets plane surpasses inlet height; Then seal up this injected hole, so repeatedly until all injected holes are completely populated;
(iii) shutoff slurry outlet; When this crack of repairing injected hole bottom starts to flow out repair sheets, with adhesive tape, seal slurry outlet; Grouting reparation to this crack completes;
(iv) completing crack repairs; Repeat (i)-(iii), with same method, successively slip casting is carried out in other cracks, until all noted.
Described step (ii) in, if crack is horizontal joint, injection process is carried out to another section successively from the one end in crack, additive method is with vertical or dipping fracture is consistent.
Beneficial effect of the present invention is:
1, with high pressure manual grouting pump, replace artificial smear crack and can significantly increasing work efficiency, simple in structure, swift to operate;
2, improved Water slop injector, caliber is less, and grout nipple front end is taper or trapezoidal shape, and import department is provided with non retern valve; To dwindle the fluid column area of perfusion, increase syringe needle and can go deep into degree, and strengthened the pressure while spraying, when repairing minute crack, repair sheets are injected to darker position, reach the object that deep layer is repaired;
3, Water slop injector can reuse, and saves capital.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, 1, action bars, 2, cartridge, 3, pressure meter, 4, Water slop injector, 5, coupler, 6, extension, 7, needle point; 8, grout pipe.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
