青岛贵都大厦地下室片筏及挡土墙施工中 ,为避免因干缩、冷缩引起的开裂、渗漏 ,采取了减小混凝土入模温度 ,控制片筏混凝土内外温差 ,设立降水井降水兼抗浮及堵井等措施 ,保证了施工质量 ,并起到了抗裂防渗作用。 In the construction of the basement and retaining walls in the basement of Guidu Building, Qingdao, in order to avoid cracking and leakage due to shrinkage and shrinkage, the temperature of the concrete entering the mold was reduced, and the temperature difference between the inside and outside of the concrete was controlled, and the precipitation well was established. Measures such as anti-floating and plugging wells ensure the construction quality and play a role in anti-cracking and anti-seepage.
