Abstract

The invention relates to a construction method of mass concrete temperature decrease and crack prevention by utilizing a thin-walled corrugated pipe circulating water system, which comprises the following steps: (1) selecting circulating water pipes: selecting thin-walled iron-sheet corrugated pipes as the pipeline materials for arranging circulating water pipes; (2) arranging a circulating waterpipe system: in the process of binding a reinforcing cage, installing and fixing the corrugated pipes to the reinforcing cage in a spiral or laminated way according to the structure form of a mass concrete, wherein, the distance between layers is from 500 mm to 2000 mm, the distance between rows in the layers is also from 500 mm to 2000 mm, and providing a water inlet pipe and a water outlet piperespectively connected with the corrugated pipes on the upper part of the mass concrete; (3) arranging temperature measuring points; (4) pouring the concrete; and (5) keeping maintenance. The construction method has the advantages of obvious effect on the temperature decrease and crack prevention of the mass concrete, low cost, simple operation, convenient and quick construction and convenience in the connection of the corrugated pipes.

Description

Construction method of cooling and anti-cracking large-volume concrete using thin-wall corrugated pipe circulating water system technical field The invention relates to the field of building engineering construction, in particular to a construction method using a thin-walled corrugated pipe circulating water system for cooling and cracking of large-volume concrete. Background technique Mass concrete construction is very common in modern construction projects, and the construction technology for cooling and cracking of mass concrete is more and more commonly used in construction sites. However, how to effectively cool down and resist cracking of large-volume concrete, ensure construction quality, reduce construction difficulty, and reduce construction cost has become a practical problem that needs to be solved urgently. In order to effectively control the surface cracks and through-cracks of mass concrete caused by temperature stress, the temperature shrinkage stress is us...
