The invention relates to a shaped integrated staircase for foundation pit construction. The shaped integrated staircase for the foundation pit construction is a rugged integrated shaped product composed of a staircase base body, security handrails, upper end fixing members, pit bottom fixing members and continuous connecting members, traction supporting members and step supporting members; throughthe upper fixing members and the pit bottom fixing members, the limiting fixation, the disassembly and displacement, and the recycle can be achieved according to demands; and the effective working length is extended with the help of the connecting members, and the use requirements of different depth foundation pit construction sites can be met. According to the shaped integrated staircase for thefoundation pit construction, the structure is scientific and reasonable, the arrangement is convenient, time-saving and labor-saving, and the work is safe and reliable; the shortcomings that in the prior art the frequent construction and disassembly of the foundation pit construction staircase is laborious and time-consuming, the material consumption is high, the arrangement cost is high, potential safety hazards exist and the phenomenon of wasting of resources is serious are overcome, the positive technical effects that the management is civilized and the production is safe, the constructionis efficient and the construction cost is reduced are bought to the construction industry and the positive technical effects are economical, practical and environmentally friendly, and the practicability is extremely high.
