4) concretes vibrating beat one important ring being to ensure that the concrete is closely knit , defend against to seep with a stick. Also, should adopt fixed point vibrating , handle meticulously on basis expecting that under determining the amounts of the components of a substance homogeneously in fixed point .Pay attention to high and low tier of linking up
Now that needing to prevent from miss and vibrating , not vibrating enough , being going to prevent a fault from vibrating again, Need to forbid using prying the method coming to aid to vibrate moving a reinforced bar or shaking a reinforced bar especially, such separates to making the front already concrete the reinforced bar and concrete shaking the reality part , causes serious consequences.
5) being ready for the assured source of life degree taking over thick fluid measure , adjusting in time to collapse seriously .Average water-proof concrete structure construction, the construction joint being under construction respectively , composing namely on erecting wall sells be bottom board and vertical wall at reduced prices.Should irrigate thick a layer of 5 cm ~ 10 cms surname indicia cement mortars in seam place first linking up closely knitting tier, in order to ensuring that the seam place vibrates when concrete vertical wall.Simultaneous , improve step by step with concrete an altitude'.Should fall off step by step with the water yield , diminish collapsing to fall degree prevent from concrete insist to be short but the cement paste is partial to much phenomenon to aggregate appearing on upper part.
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 lienable 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 lienable construction joint of perpendicularity direction like the concrete , rubber stops in having set up the construction joint irrigating belt , perpendicularity directionthe day afer 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
