Large-volume concrete self-circulation temperature control maintenance system and method

Abstract

The invention relates to a large-volume concrete self-circulation temperature control maintenance system and method. The large-volume concrete self-circulation temperature control maintenance system comprises a water storage frame, a cooling water pipe, a water pump, a cooling water temperature monitoring mechanism, a concrete temperature gradient monitoring mechanism and a water storage temperature sensor; the water storage frame is arranged at the top of large-volume concrete and used for forming a water storage pool; the cooling water pipe is pre-embedded into the large-volume concrete, and a water inlet and a water outlet communicate with the water storage pool through a connection pipe to form a circulation water route; the water pump is arranged on the circulation water route; the cooling water temperature monitoring mechanism is used for monitoring the temperature of cooling water; the concrete temperature gradient monitoring mechanism is used for monitoring temperature gradient distribution of the large-volume concrete; and the water storage temperature sensor is arranged in the water storage pool and used for monitoring the water storage temperature. Compared with the prior art, through water resource cyclic utilization, water is not required to be supplemented additionally in the process of maintenance temperature control, maintenance water is heated by hydration heat of binding materials, energy recycling is realized, and the temperature control cost is saved.

[0001] The invention relates to the technical field of large-volume concrete engineering construction, in particular to a large-volume concrete self-circulation temperature control maintenance system and a maintenance method. Background technique

[0002] Temperature stress is a key factor that cannot be ignored in the construction process of mass concrete. The large volume of concrete makes it difficult to dissipate the heat generated by cement hydration, which causes the internal temperature of the concrete to be too high and forms temperature stress, which leads to cracking of the concrete structure and seriously affects the safety of the structure. and functionality. Embedded cooling water pipe cooling is currently the most effective way to reduce the internal temperature of mass concrete. Cooling water temperature control is the key to affect the cooling effect of water pipes. If the cooling water temperature is too low, a temperature gradient will be f...
