Mass concrete cooling device and process

Abstract

The invention discloses a mass concrete cooling device and process. The mass concrete cooling device comprises a thin-wall steel pipe pre-buried before mass concrete is poured, wherein after the mass concrete is poured, the top of the thin-wall steel pipe exposes the mass concrete; temperature conducting liquid is poured into the thin-wall steel pipe; the top, exposed out of the mass concrete, of the thin-wall steel pipe is connected with a finned pipe; the temperature conducting liquid at the bottom in the thin-wall steel pipe is sealed in a closed cavity formed by the thin-wall steel pipe and the finned pipe; the temperature conducting liquid is a material which is used for cooling the mass concrete after the concrete is poured into a mold and heated to reach a boiling point, vaporizes to absorb heat, rises into the finned pipe, is in contact with the environment temperature in the finned pipe, is cooled to be lower than the boiling point, becomes liquid and flows back into the thin-wall steel tube, and the cycle is repeated. The purpose of effectively cooling mass concrete is achieved, the construction cost is low, operation is convenient and fast, and the method is suitable for popularization.

Description

technical field [0001] The invention relates to a device and process for cooling large-volume concrete, and belongs to the technical field of cooling large-volume concrete. Background technique [0002] At present, mass concrete construction is often involved in building construction. The temperature stress in mass concrete is one of the common reasons for the cracking of concrete itself, especially during the construction of mass concrete, the hydration of concrete will generate a lot of heat, if the heat cannot be effectively and uniformly dissipated, a large temperature stress will be formed , thus causing the concrete to crack and reduce the construction quality. It can be seen that temperature control of mass concrete can directly affect the quality of mass concrete construction. At present, the common practice in the industry is to pre-embed cooling water pipes for heat dissipation inside the large-volume concrete. This existing practice requires on-site equipment su...

Problems solved by technology

At present, the common practice in the industry is to pre-embed cooling water pipes for heat dissipation inside the large-volume concrete. This existing practice requires on-site equipment such as water pumps and water tanks, and requires constant pumping and changing of water, which is very cumbersome and time-consuming. , higher construction cost
