地下室剪力墙混凝土浇筑技术交底(国外英文资料) Cooperate with each other in a timely manner. Mouth leveling: 9. The wall concrete vibratory finished, will be flowing out of steel and arrange them, wood float line according to the elevation control (1 or 2 cm higher than the bottom of the roof), the surface leveling. Pay attention to the sealing of the site of the construction. Do the construction of concrete insulation and test block. Wall concrete block as required field should take a set of standard curing test block, spare piece of a group (such as concrete volume is big, should be in accordance with the requirements of test), 1 ~ 4 groups with the condition maintenance test specimen: 1 set to test intensity of 7.5 MPa, a set of testing strength of 1.2 MPa. Winter: concrete should be increased 2 set of block 1 set of critical strength, frost resistance measurement about 27 d, should be combined with temperature, the temperature dropped to antifreeze in structure temperature before testing, determine whether more than antifreeze critical strength 4 mpa, such as short of 4 mpa, continue to cool, it could freeze, should increase heat preservation, heat curing measures, such as strength of cold noodles more than 4 mpa; The other group measured the intensity of the temperature in winter, and then maintained the 28d after winter. 11. On the same terms and conditions of concrete test report data provided by the good control of time to dismantle (with conditions block intensity reached 1.2 MPa), when the split mould wall non-stick mold, no corner, no cracks, no coagulation + quality defects, to achieve smooth level off, the quality requirements to achieve the requirement of the specification, maintenance according to the actual conditions with different methods. The demolition module must be approved by the technical director of the project department, otherwise it will not be removed. Wall concrete curing: the concrete of the wall should be patted by special people. Water spray curing should
