2.5 The method of Construction joint
The construction joint is one of water-proof architectural weak link. The construction joint is one of water-proof architectural weak link. Should stop staying or not staying to the full equipment or props up conditional restricting of model, may then behind the agreement collecting a design organ, on the wall stipulating that lien able level of location construction joint , sort keep vertical strokes getting along in all above 200 bottom board .Adopt new handicraft expansibility in the project rubber water just brings handling the construction joint method , substituting method in common use , anxiously expecting the dyadic construction joint of mouth , at any rate dyadic construction joint , flat mouth construction joint such as and so on .Water proofing is in no lien able construction joint of perpendicularity direction like the concrete , rubber stops in having set up the construction joint irrigating belt , perpendicularity direction the day after tomorrow between the main building and the skirt building interposing expansibility in seam location water belt or steel plate stops water belt weak link of water-proof structure, respond to specially-assigned person conscientiously , handle meticulously . Ensure mass to be under construction in construction. Adopt to stop having not to miss and not soldering time water steel plate, adopt rubber water belt just should be solid without fail reliably in receiving long time will connect using special use glue to paste. When only think that concreting accepts.
2.6 Dismantling model and curing of concrete
The water-proof concreting queen maintains goodness and badness working, not only affecting the intensity arriving at a concrete, moreover the impervious function affecting to the concrete. Evidence, water-proof concrete early phase dehydration or curing process lack for water, will reduce whose impervious function by a wide margin. Water-proof concrete curing responds to the block of wood less than 14 ds.
The water-proof concrete dismantles a model demanding to be unable to compare high , dismantle model time unsuitable untimely, respond to when dismantling a model handle meticulously, prevent an iron rod from using to pry, stiffly, that the sledgehammer is knocked suddenly and forcibly pries, uses a concrete meet with destroy.
2.7 Do good well at backfill
Water-proof architectural backfill is a final working procedure, it be sometimes ignored, this is a very big faults in fact under the ground. When the water-proof structure job is over queen responds to the construction carrying out backfill immediately. Most important, we should take backfill seriously self mass; Secondly, backfill varia and ponding should clear up the pit bottom in the front, respond to densification with layers when backfill. Water-proof structure vicinity layer pounds true backfill; self is a reliable and economical as well water proofing drapery under the ground. In project basement engineering construction Shanghai, since organizing water proofing down to earth strictly with all above seven passes, the concrete is under construction, effect is comparatively ideal. The percolating water phenomenon does not appear.
3. Conclusions
Construction temperature and relation of crack in concrete the above carry on preliminary discussion of theory and practice, though the academia has different theories to origin cause of formation and computing technology of the concrete crack, but to concrete prevention and improving the measure suggestion to relatively unify , application in practice result fine too at the same time, concrete to is it observe , compare more by us to want in constructing, analyze more , summarize more after going wrong , combine many kinds of prevention and deal with the measure, the crack of the concrete can be avoided.
