Description

technical field

Background technique

For extra-high arch dams, the focus of anti-cracking during the construction period is concrete temperature control. The temperature problem of arch dam concrete should be solved mainly from two aspects: controlling temperature and improving restraint. From the perspective of temperature control, the concrete pouring temperature, the maximum concrete temperature and the final stable temperature are three characteristic temperatures, and the maximum temperature is equal to the pouring temperature plus the temperature rise of the heat of hydration. The final stable temperature depends on the local climate conditions and the structural form of the dam body, so the main control in engineering is the pouring temperature and the temperature rise of the heat of hydration.

At present, the pouring temperature control in the construction of high arch dams is mainly controlled through the coordinated control of the flow temperature valve and the control center. However, the existing flow temperature valves are usually arranged in a scattered manner, and the wiring is chaotic, and there is no control cabinet, which is not conducive to on-site installation and debugging.
