Summary:The invention relates to the technical field of foundation and foundation engineering, and discloses an anchor cable construction method for intelligently detecting the hole expanding aperture. The method comprises the following steps that 1), the anchor cable hole position is measured and determined, a striking mark is marked, and a drilling machine is installed by contrasting the mark; 2), after the drilling machine is positioned and the angle is adjusted, drilling is carried out for hole forming, and high-pressure air is used for completely removing rock powder and water in a hole out of the hole; 3), a hole expanding drill bit is replaced, water is added for hole expanding, and after hole expanding is completed, water is injected for hole washing two to three times; 4), after hole washing is completed, a cable of an ultrasonic aperture probe penetrates out through a drill rod to be connected with background measuring and reading equipment, real-time aperture detection is carried out on hole expanding thro
