Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific embodiments.

[0021] A system for controlling cracks in large-volume concrete by using circulating water, the system includes a well pipe dewatering well, a circulating water pipe, a temperature-regulating tank, a cooling pool, large-volume concrete, and municipal drainage ditch; the waste water in the well pipe dewatering well is introduced into the cooling In the water circulation system, the temperature regulating tank, the cooling pool and the municipal drainage ditch are connected into an organic whole to form a system for circulating water to control the temperature cracks of mass concrete.

[0022] Specifically, the well pipe dewatering well is connected to the temperature-regulating tank through a circulating water pipe; the temperature-regulating tank is symmetrically distributed at both ends of the cooling pool, and the large-volume concrete is placed inside the cooling pool; M...

Abstract

The invention discloses a system and method for efficiently controlling cracks of a big cubage concrete base through circulating water and belongs to the technical field of structural engineering. The system for efficiently controlling the cracks of the big cubage concrete through circulating water is quite suitable for construction of a bottom plate of the big cubage concrete base. According to the method, a well casing dewatering well, a temperature regulating trough, a cooling tank and municipal drainage ditches are connected together through circulating water pipes, waste water in the well casing dewatering well is effectively utilized, residual heat on the surface of concrete is exchanged out through circulating water according to circulating water accumulation, the temperature difference between inside and outside of concrete is reduced, the possibility that temperature cracks of the big cubage concrete are generated is lowered greatly, and low carbon and environmental friendliness are achieved at the same time.

Description

technical field [0001] The invention relates to a system and a method for controlling cracks in large-volume concrete by using circulating water, and belongs to the technical field of construction engineering. Background technique [0002] With the development of science and technology, concrete materials have become the first choice of modern engineering building materials due to their advantages of convenient construction, large bearing capacity, and strong decoration (according to relevant data, the current annual concrete consumption in the world has exceeded 70%. billion m 3 ). In recent years, with people's pursuit of use functions, concrete structures are developing towards a comprehensive direction of bulky, complex structures, and diverse functions, especially in large-volume structures, such as concrete dams, road and bridge projects, housing construction, etc. field. But concrete is a kind of quasi-brittle material, which is mainly used to bear the load and pre...
