Description
Technical field
The present invention relates to field of detecting, be specifically related to build inspection field.
Background technology
The leakage of buildings problem is comparatively general common quality defect, many buildingss are in use found the phenomenons such as roof leakage, wall infiltration, rendering layer come off, day by day, roof, interior metope can peel off because large tracts of land appears in seepage, and because long-time seepage, humidity cause going mouldy, directly affect housing quality.The work such as office, machine room, workshop produce institute as for a long time seepage will badly damaged office facility, the operation of exact instrument, machine tool etc., even cause electrical short-circuit.Seepage not only upsets people's normal life, work, the production order, and directly has influence on the serviceable life of whole solitary building.
Seepage in the face of the roofing appearance, the normal way that adopts of people is: the new mortar surface layer of making again after whole roofing screed is removed, or the waterproof roll of whole roofing is all reformed, this way has certain blindness, and a large amount of man power and material of cost is carried out water-proofing treatment.
When disease that larger area causes due to infiltration appears in roof or body of wall, as scaling, watermark, heave and even leak etc., represent that namely more serious infiltration disease has appearred in this roofing, conventional way is to roofing making waterproof roll or renovate screed again comprehensively comprehensively.Hardly realize, the real seepage part that exposes may only have a single point, and may be namely that position, negative and positive angle is processed not in place or roofing is combined with parapet have occurred breakage somewhere, referred to herein as " water source point ".The crack that the water that infiltrates from here will exist in roof construction layer or wall body structure begins continuous injection, spreads and spreads.Infiltrate the water of body of wall or roofing, in case run into the position of through crack, will leak out from the inside surface of body of wall or roofing, present so-called drainage, cause the affiliated facility on surface to produce functional damage, and the leakage point of this moment or dried up source point is far away.
Permeation pathway how accurately to orient the water that enters from " water source point " is building structure slabbing seam, is key problem in technology of the present invention.
