The two rails 11 are symmetrically arranged on both sides of the folding component 12. When folding the support frame, one rail 11 is translated toward the other rail 11. The two connecting rods 15 included in each folding component 12 are folded in half and finally placed side by side. The distance between the two rails 11 is greatly shortened, so that the support frame is in a folded state; the entire support frame is a foldable integral structure. When in use, the support frame is directly hoisted into the construction well at one time, and then the support frame is unfolded and laid at the bottom of the construction well, avoiding the problem of multiple hoisting of steel frame parts and on-site assembly when using a general support frame, making the laying of the support frame in the pipe jacking method pipeline project simple and efficient.
