The specific embodiment
Below introduce specific embodiment of the utility model in detail.
A kind of self-pressing crack treating device, it is characterized in that comprising slurry storing tank 5 cylindraceous, one end of slurry storing tank 5 is closed, there is the connector 8 of band through hole the centre, the piston 3 of band guide rod 4 is housed in the slurry storing tank 5, mounting spring 2 contacts with the counter-force lid 1 that is fixed on slurry storing tank 5 other ends on the guide rod 4, constitutes the piston spring propulsive mechanism; One end of guide rod 4 passes the hole that counter-force is covered 1 center, and there is limiting tooth 7 at the edge of guide rod 4, and the bore edges that counter-force is covered 1 center has the notch 6 that matches with limiting tooth 7, and with the grout nipple 10 that connector is spirally connected and links to each other, the plug 9 that can screw in grout nipple constitutes.
Annex comprises the grout nipple 10 that can be spirally connected and link to each other with connector, can screw in the plug 9 of grout nipple.
Outside connector 8, the plug 9 pin thread is arranged, in the grout nipple 10 negative thread is arranged.
Can be spirally connected with connector has excessive glue hole 11 around the grout nipple that links to each other 10, can show the perfusion situation.
A plurality of grout nipples to the grouting process flow process that distress in concrete carries out chemical grout are simultaneously: the fracture faces cleaning---paste grout nipple and sealing crack---configuration of grouting glue and check---, and porous is in the milk synchronously.
1, fracture faces cleaning
Remove distress in concrete surface plastering layer, laitance, foreign material, greasy dirt etc., expose clean concrete surface;
2, paste grout nipple and sealing crack
Grout nipple is by the fracture strike setting, spacing 200～500mm, be located at crosspoint, crack, crack broad place and the position apart from about the 100mm of end in principle, the grout nipple spacing can be bigger when crack width was big, a crack width hour grout nipple spacing should reduce, every lacinia is stitched to two grout nipples is set less, as advancing slurry, exhaust or slurry outlet nozzle, and standby each other.To the grouting of cast-in-place plank split, grout nipple can be located at the bottom of the plate or the plate top, and the grout nipple position of concrete beam can be located at beam sides and bottom surface, and all the other surface of positions of crack all should use joint seal glue to be sealed.
After the joint seal adhesive curing, the joint seal obturation effect is checked in the leak test of should calming the anger test, observes connection situation between the grout nipple.If still stuffiness of grout nipple illustrated that then this position is not communicated with other grout nipples when air pressure reached 0.2MPa in the grout nipple, should bury grout nipple again underground, and reduce the spacing of grout nipple;
3, configuration of grouting glue and inspection
Grouting glue should dispose behind the grouting conditions being possessed, and checks the viscosity of grouting agent before the grouting, and the heating that do not have, the phenomenon that is clamminess should be able to guarantee to pour in the seam smoothly;
4, grouting
4.1 connector is extended in the grouting liquid, pull out piston guide rod, suck grouting glue, the rotary-piston guide rod makes limiting tooth be stuck in counter-force and covers, and blocks spring.
4.2 self-pressing crack treating device is in place and grouting should be by principle in place in proper order from top to bottom.The self-pressing crack treating device connector is screwed in the grout nipple, and the screw-in dynamics is moderate, in conjunction with closely being advisable, base is come off to guarantee both, and too Song Zeyi makes grouting liquid overflow from grout nipple.
4.3 the rotary-piston guide rod makes limiting tooth smoothly by counter-force lid notch, begins grouting.
Occur one of following sign person in the filling process, show that all the crack fills with slurries in this position, place, can change next grout nipple over to,, also can adopt a plurality of self-pressing crack treating devices to pour into simultaneously until filling complete strips crack;
A, under grouting pressure if the top grout nipple has slurries to flow out, the timely grout nipple of jam-pack top spillage, keep former operating pressure 1～2min after;
Do not see in b, the slurries in remaining in slurry casting machine (these slurries must not generate heat, the retrogradation) 5min to pour into, or inhale the slurry rate less than 0.05L/min.
Quality control: use plug and block offside, should check before each encapsulating whether tightness and glueing channel be unobstructed, advances glue speed from fast to slow, if spillage, the rotary-piston guide rod makes limiting tooth be stuck in counter-force and covers immediately, to reduce the pressure in the crack.
It is 55g that self-pressing crack treating device once can be adorned amount of resin, and effectively injection rate 45g can continue to replenish when once injecting deficiency.
4.4 after this position grouting finished, the rotary-piston guide rod made limiting tooth be stuck in counter-force and covers, and screws off self-pressing crack treating device.
4.5 carry out the operation of next grout nipple.
4.6 finishing the back, grouting cleans self-pressing crack treating device.
