分步浇筑大体积混凝土冷却水管一体化布置控裂技术.

In order to solve the problem of high temperature gradient near the construction joints in the step-by-step construction process of concrete engineering, an integrated cooling water pipe crack control technology based on step-by-step casting was proposed based on the traditional cooling water pipe, and the influence of the technology on the internal temperature of concrete was studied by embedding temperature measuring points. The results show that in the process of "twostep" concrete temperature rising, the temperature of "one-step" concrete can be raised evenly and synchronously with the integrated cooling water pipe crack control technology, which strengthens the uniformity of temperature change of step-by-step casting of concrete. It can significantly reduce the temperature difference on both sides of the of construction joints, improve the uniformity of temperature, and significantly reduce the number, width and length of cracks.
