Construction method for hanging elevator shaft

The invention discloses a construction method for a suspension elevator shaft. The construction method comprises the following steps: 1, constructing a suspension framework; secondly, an elevator shaft bottom plate is constructed; 3, constructing a third-layer prefabricated wallboard; 4, constructing a second layer of prefabricated wallboards; 5, constructing a first layer of prefabricated wallboards; sixthly, a suspension framework deformation monitor is pre-buried; and 7, performing waterproof and anti-seepage treatment. According to the construction method, the simulated construction suspension framework is adopted from top to bottom, a mounting foundation is provided for the prefabricated wall plates of the suspension elevator shaft, it is avoided that a supporting foundation layer is laid in a basement elevator descending plate, then the prefabricated wall plates are sequentially assembled from bottom to top, construction is in order, the construction procedure that the supporting foundation layer is dis
