the admeasurement concrete at the regular intervals collapsing in the process being under construction , construction is middle if Yu rains or other cause, respond to the ratio determining whose water ratio, and adjusting the position being under construction in time when change happened in sandstone moisture content. (4) project uses the modity concrete , has boundary have raised a concrete stirring mass and of all kinds effect apposition agent adulterating falls when amounts , the water ash having controlled a concrete strictly collapsing. (5) concretes concrete adopt a pump to have given handicraft , effective avoiding a concrete producing the phenomenon isolating Mi Shui and leaving out thick fluid in the process of transportation. Matters needing attention in being under construction (1) construction school assignment soft and floury is divided . (2)Achieve strictly fixed point determines the amounts of the ponents of a substance material down According to the vehicle capacities stratifying concrete altitude and the means of transport, the quantify carrying out fixed point strictly is able to go down one important ring expecting that this is to improve waterproof concreting mass. (3) insist that you go down material opening the door or use string to expect that under barrel (chute)Be to prevent a cement paste from parting from aggregate for , to expect that liberty should not exceed ms now and then highly under waterproof concrete. (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 ponents 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 ing 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. The method of Construction joint The construction joint is one of waterproof architectural weak link. The construction joint is one of waterproof 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 an, 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 mon 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 link of waterproof structure, respond to speciallyassigned 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
