Abstract
A construction method of a rectangular working well includes steps of: (I) designing functional requirements for the rectangular working well; (II) constructing a caisson of an enclosing structure of the rectangular working well; (III) constructing an edge protector; (IV) excavating earthwork of the rectangular working well; (V) forming a bottom cover for the rectangular working well, and pre-embedding a sliding track, a pull ring and a back wall anchor; (VI) installing a ladder for entering the rectangular working well; (VII) preventing joint leakage; (VIII) installing a water-proof pressure plate at an entrance of the preset pipe jacking hole; (IX) constructing the sliding back wall; (X) lifting the sandwich concrete slab wall at a top of the preset pipe jacking hole; and (XI) performing pipe jacking. The structure system constructed by the present invention has many advantages such as clear function, safety, quickness, and flexible design.
