Research on the Causes of Cracks in Reinforced Concrete Vertical Overflow Weirs and Construction Techniques for Crack Treatment
Reinforced concrete vertical overflow weir often produces crack structure,which will affect the overall safety and stability of the building.In this paper,the causes of cracks and treatment construction technology are studied,and the causes of cracks in reinforced concrete vertical overflow weir are obtained.It includes improper design of concrete mix ratio,unreasonable construction technology,poor operating conditions and so on.On this basis,combined with the frost heave crack treatment of vertical overflow weir,increasing the thickness of outer concrete,strengthening concrete drainage and electrothermal moisturizing of overflow weir surface,a new crack treatment construction technology is proposed.The results show that the application of the new construction technology can effectively reduce the number of cracks on the overflow weir,and control the length,width and depth of the cracks within the specified requirements,so as to ensure the overall stability of the structure.
