Description
Technical field
The invention belongs to construction engineering technical field, be specifically related to that a kind of building masonry wall crack is convenient fills up device and construction method thereof.
Background technology
Wall body slit is the cracking phenomena of the wall part generation of building structure, according to the difference of material self material, it is possible to be divided into following four kinds. One is concrete wall crack. Two is brick setting wall body slit. Three is Novel partition plate crack, such as GRC plate, plasterboard crack etc. Four is the crack that unlike material body of wall produces, and such as the cracking between concrete and brick setting, this type of crack often occurs, such as construction crack, hole.
The grouting method of a kind of penetrability distress in concrete disclosed in the Chinese invention patent application of notification number CN103174112A, it is characterised in that comprise the following steps:
Boring: including inclined hole, roulette, described inclined hole is arranged in homonymy or the both sides in crack, described roulette carries over crack to Slit bottom;
Pipe laying: adopt Binder Materials to bury underground;
Joint seal: include raggle method, surface joint seal method, when adopting raggle method, the filler in its groove can adopt epoxy resin mortar or polyurethane sealant or acrylamide sand grout or cement mortar or pre contract mortar; When sealing is for wet sealing, adopting surface joint seal method, filler can be selected for accelerated cement or cement-silicate or leak stopping spirit;
Grouting: during the grouting of the Vertical Cracks of facade, R-joining, from one grout hole of bottommost, hole-specifically go up decant(-ation) slurry from bottom to top, progress along with filling process, serosity gradually rises in seam face, when one grout hole pulp of topmost, it was shown that seam is filled, then close grout pipe valve, when reaching ending standard, terminate grouting;
The horizontal fracture of facade or close to horizontal crack owing to the discrepancy in elevation is little, vent ratio Vertical Cracks is poor, all grout holes should be opened before grouting, grouting make after starting serosity from inner outwards, flow to the other end from one end, in the process during adjacent holes pulp, go out one and close one, until after last grout hole pulp, it is turned off, when reaching ending standard, terminates grouting;
Crack in plane is chosen best one grout hole of patency and is started grouting, then executes filling to both sides simultaneously;
By above-mentioned steps, complete distress in concrete grouting.
The device that and for example present invention uses disclosed in the Chinese invention patent application of notification number CN101109231A includes packer and slurry can.
