+ Do not misrepresent the position, location of the planking and the thickness of reinforced protective layer.+ Do not use intermittent punching to horizontal shift in the concrete planking.+ Concrete must be poured repeatedly until the completion of a certain structure as required by the design.+ Avoiding stratification, free fall height of concrete when poured should not exceed 1, 5 m.+ When pouring concrete have free fall height > 1.5 m to use tilt chutes or tubes of Heliotrope. If height > 10 m must use the tube shock devices have Heliotrope.+ Closely monitor the current state of educational support and reinforcement steel planking in the construction process.+ The level of the thick concrete poured on the planking must match the calculated metric rigidity of horizontal planking pressure due to new concrete mix pour cause.+ When the rain must have shielding measures not for rain water falling on the concrete.+ The thickness of each layer of concrete poured must base on the capacity mix, transport, the ability, the nature and weather conditions to the decision, but must follow the rules.+ Pour concrete foundations: make sure the regulations on foundations and concrete just pour on the clean cushion on hard ground.+ When pouring concrete company continue on old grade sanitary measures required surface, use brushes for cleaning, water and cement concrete pouring heavily.
