Equipment and Method for On-site Testing of Water Resistance Performance of Exterior Walls of High-rise Buildings Technical Field
[0001] This invention relates to the field of external wall impermeability testing technology, specifically to an on-site testing equipment and method for the impermeability of external walls of high-rise buildings. Background Technology
[0002] Building exterior walls, which are made of concrete, must have the basic function of preventing rainwater and snowmelt from penetrating the wall. They should also have properties such as freeze-thaw resistance, high and low temperature resistance, and wind load resistance. Concrete is a porous material with pore sizes of varying sizes (10~500μm). When there is a pressure difference (or concentration difference, temperature difference, or potential difference) in the surrounding medium, there will be medium migration that follows fluid mechanics, i.e., permeation. The impermeability of concrete is a basic property of concrete and an important characteristic of concrete durability. The impermeability of concrete not only characterizes the ability of concrete to resist water flow, but also affects the concrete's resistance to carbonation and chloride ion penetration.
[0003] The waterproofing strength of the exterior walls of high-rise buildings varies, and it is often necessary to determine the impermeability of the exterior walls. Existing testing methods often require high-altitude testing, which is relatively difficult to perform, involves high-altitude operations, and is too complicated to test the impermeability.
