摘要
本方案利用冻结壁内循环常温水以保持井壁内侧温度的思想,将冻结站冷却水循环系统同冻结壁内侧常温水循环系统相连接,以降低冷却水温度并保证井壁内侧温度在0~5℃之间,以确保混凝土正常硬化提高井壁强度和抗渗性能.
The idea of the schema is to improve the circle normal temperate water in the frozen wall To keep the temperature of the inner of the well wall. connect the circle system of cool water in the freezing, bosom with the water system of normal temperate water in the inner of the frozen wall, to reduce the temperature of the cool water to ensure the temperature of the inner of well wall is between 0 ~ 5 ℃ , to assure the concrete to be harden normally and improve system the intention and the ability of strength leak of the well wall.
