Square culvert jacking construction device, system and method

The invention provides a square culvert jacking construction device, system and method, and relates to the field of geotechnical engineering.The square culvert jacking construction device comprises a rectangular tubular jacking body, one end face of the jacking body is a diagonal plane forming an acute angle relative to the axis of the jacking body so as to act on an excavation position to form an inclined tunnel face, and the other end face of the jacking body is provided with a perforated baffle; a soil bin is formed between the perforated baffle and the diagonal plane; a plurality of excavation rollers which are sequentially arranged at intervals are mounted at one end, close to the diagonal plane, of the soil bin; aiming at the problem that current square culvert jacking construction easily affects ground facilities, culvert jacking construction is carried out by arranging a rectangular tubular jacking body with a diagonal plane, a rectangular culvert meeting the square culvert requirement is formed, the
