Cooling system for construction of mass concrete structure

Abstract

The invention relates to the technical field of bridge building construction, in particular to a cooling system for construction of a mass concrete structure. The cooling system comprises a plurality of cooling pipes arranged in concrete, wherein a water inlet is formed in one end of each cooling pipe; a water outlet is formed in the other end of each cooling pipe; the water inlet communicates with a water source; and the cooling system further comprises a pumping device which is used for pumping water from the water source into the cooling pipes. According to the scheme, during the casting process of the mass concrete structure, the cooling pipes are arranged in the concrete, the pumping device is started, cooling water from the water source enters the cooling pipes via the water inlets and then are drained via the water outlets, and the cooling water takes away heat of hydration in the concrete, so that the temperature difference between different parts of the mass concrete structure is reduced, and then the thermal stress in the mass concrete structure, the residual stress after hardening of the concrete construction and the risk of cracking of the concrete construction are reduced. Therefore, the structural quality of the mass concrete structure is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bridge building construction, in particular to a cooling system for the construction of large-volume concrete structures. Background technique [0002] As a common structure spanning complex terrain, bridges are important transportation infrastructure for modern construction. During the construction of bridges, a large number of concrete pouring processes will be involved. For large concrete structures such as bridge caps, how to Ensuring the pouring quality of concrete is an unavoidable problem in bridge construction at present. [0003] At present, the usual solution includes two aspects. One is the improvement of the material components of the concrete itself. By using different proportions of components and different additives, the performance of the concrete itself is improved to ensure this type of large volume. The performance of the concrete structure; on the other hand, it is to improve the curi...
