The invention discloses a hanging basket for constructional engineering high-altitude construction. A single side of a suspending platform in the structure is provided with an extension part extending to the outer side of a guard bar. The guard bar corresponding to the extension part is provided with a gap for constructors to get in and out. An electric control box is fixed on the guard bar of the side of the suspending platform. A base plate is above the suspending platform. A pair of conductive contacts which are connected in series with a power circuit of an elevator in an Ohmic manner, and a first spiral spring are between the base plate and the suspending platform. The first spiral spring is between the conductive contacts and separates the conductive contacts, and is made of an insulating material. When an adult steps on the base plate which is close to the extension part of the suspending platform by both feet, the first spiral spring on a pair of threaded guiding posts are compressed, and the pair of conductive contacts corresponding to each first spiral spring are absorbed with each other. The hanging basket solves a technical problem of improving use security of hanging basket for constructional engineering high-altitude construction, and can effectively reduce high-altitude construction risks of constructors.
