Mass concrete cooling water circulation and construction method

Abstract

The invention discloses a mass concrete cooling water circulation and construction method, and belongs to the field of mass concrete construction in constructional engineering. The mass concrete cooling water circulation comprises a water circulation module and a water storage module, the water circulation module comprises a conveying pipeline, the conveying pipeline is laid in a pouring pit, anda waterproof wall is arranged along the upper surface of the pouring pit. The waterproof wall is suitable for storing water and curing concrete, the water storage module comprises a flow dividing branch pipe and a control part, and an inlet of the flow dividing branch pipe is formed between a water storage tank and a cooling tower. The flow dividing branch pipe is suitable for guiding water into the waterproof wall, and the control part is located at the port, close to one end of the water storage tank, of the flow dividing branch pipe and suitable for controlling the flow direction of water of the flow dividing branch pipe. The surface, located in the pouring pit, of the conveying pipeline is a protruding part, and the protruding part is suitable for conveying water of the waterproof wallinto the conveying pipeline in the concrete in the water flow direction. The problems are solved that large temperature difference is generated and rapidly reduced when an existing drainage pond stores water for curing the surface of the concrete and water circulation is conducted in the concrete, and cracks are generated due to sudden temperature change.

Description

technical field [0001] The invention belongs to the field of large-volume concrete construction in construction engineering, and in particular relates to a large-volume concrete cooling water circulation and a construction method. Background technique [0002] Concrete pouring is an indispensable link in construction engineering, and its quality is directly related to the overall quality of construction engineering. As far as the present stage is concerned, the most common problem is mass concrete cracks, which will not only affect the appearance quality of the structure, but also affect the stability and integrity of the structure. [0003] The traditional pre-embedded circulating water pipe in concrete is formed by inlet water, outlet drainage, and brick drainage pool water storage. Due to the long curing time and the high internal temperature of the concrete, it is impossible to control the temperature of the circulating water for a long time and target the internal tempe...
