The control method of Bailey cracks

　　All the things in use after a period of time or less there will be some cracks, Bailey is no exception, then we need to control the Hunan Bailey rift
　　General strengthening early curing of concrete, concrete pouring Hunan Bailey after exposure of timely straw, straw bags or plastic film cover, and the water spray wet curing. In high temperature, low humidity and climate wind speed should enclothe, spraying water conservation, and maintenance of appropriate delay time. Avoid concrete internal restraint caused by the general situation of temperature cracks, generally take control concrete general and external or internal temperature difference of preparation, make it less than 25 degrees centigrade.
　　Often use the control method is: the components of heat conservation, should be taken to slow landing temperature, the temperature is not landing on New Year's Eve at the temperature of 10 /h, and hope to uncover, slow release, avoid the situation of temperature stress of steel bridge is too large; large volume concrete and layout, when the outside temperature is high, should Hunan Bailey take the appropriate heat preservation, director of the temperature control in the stripping time, 25 DEG C
