Abstract

The invention provides a test device and method for the whole process of concrete water cooling. The main testing machine includes a concrete specimen accommodation device, a loading system connected to the movable chuck on the concrete specimen accommodation device, and a concrete specimen accommodation space. The water cooling simulation system is set in the center, which includes a water pipe, and the water inlet and outlet pipes pass through the accommodation space to connect with the water supply device as a circuit. There are two actuators on the circuit: a cooling device and a circulating power device; Flow meter and water temperature sensor. The invention can test the development process of the concrete's own temperature stress from pouring to hardening under the conditions of various temperature control measures, and can also simulate the real meteorological environment to simulate the temperature stress and cracking mechanism. The device can be set with different temperature and constraint conditions as required. Through the simulation test of the whole process of concrete cracking, the crack resistance performance of concrete is evaluated.

Description

Technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and relates to a real environment-based simulation test method for the whole process of concrete water cooling and a test device adopting the method, more specifically, it relates to a simulation test of the whole process of water cooling of mass concrete Method and device. Background technique [0002] For a long time, "no dam, no crack" has been an unsolved world problem. The appearance of cracks affects the appearance, performance and safety of dam structures, and ultimately affects people's lives and properties. How to reduce or even prevent the occurrence of cracks has become a problem that engineering builders must consider. With the progress of theoretical and technical research in related fields, the research work on dam concrete cracks has made obvious progress, especially the work of mass concrete temperature control and crack prevention, which has forme...
