Method for controlling temperature difference between inside and outside of mass concrete

Abstract

The invention discloses a method for controlling the temperature difference between the inside and the outside of mass concrete. Cooling pipes are embedded in the mass concrete, the multiple layers ofcooling pipes are arranged along the mass concrete, each layer of cooling pipe is arranged in a serpentine bending mode, the cooling pipes are connected with an air inlet pipe, the air inlet pipe isconnected with an air pump, a plurality of temperature control tanks are connected with the cooling pipes on the outside of the mass concrete in series, the cooling pipes are arranged in the temperature control tanks in a multi-stage bending mode, an air outlet pipe is arranged at the tail ends of the cooling pipes, compressed air is introduced into the cooling pipes by the air pump, a cooling medium is arranged in the temperature control tanks, and the technical problems of low water flow cooling flow speed, low cooling efficiency and waste of water resources in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a method for controlling the temperature difference between inside and outside of mass concrete. Background technique [0002] Although water is a renewable resource, due to people's weak awareness of environmental protection, they squander water resources recklessly and over-exploit resources, deteriorating the natural environment. As a building construction industry that consumes a lot of water, there is still a lot of waste and low efficiency in the use of water resources. [0003] The strength level of mass concrete is relatively high, and the amount of cement per unit is relatively large. The heat of hydration and shrinkage can easily cause structural cracking. It is necessary to pre-control concrete cracking by optimizing the mix ratio. Because the heat of hydration of mass concrete is not easy to lose quickly, the heat is stored inside, which makes the te...
