The front tire assembly (341) touches the ground; the rear lift cylinder (332) shrinks to lift the rear tire assembly (342) off the ground; (5) The whole machine continues to walk, and stops walking when the pouring mold (4) coincides with the position of the steel skeleton. This position is the pouring position of the comprehensive pipe gallery. The oil cylinder (332) is stretched out so that the rear tire assembly (342) touches the ground, the front lifting oil cylinder (331) remains unchanged, and the front tire assembly (341) remains on the ground; (6) remotely operate the oil cylinders of all pouring molds (4), so that all oil cylinders stretch out, the pouring molds (4) are in place, and the profiling is completed; (7) Pouring concrete to complete the pouring construction of the comprehensive pipe gallery; (8) Carry out steam curing to the poured concrete; (9) Remotely operate all pouring mold oil cylinders to make all oil cylinders shrink, wherein the shrinkage sequence of each oil cylinder of the inner mold (41) is the same as step (2), so far, complete the demoulding; (10) The whole machine walks back, and when the front tire assembly (341) walks to the comprehensive pipe gallery that has just been poured, it stops walking. At this time, the lifting cylinder (33) is operated remotely, and the front lifting cylinder (331) continues to extend. out, the front tire assembly (341) is landed, the rear lift cylinder (332) shrinks, and the rear tire assembly (342) remains on the ground; (11) The whole machine continues to walk and withdraws to the position of the next construction process. So far, the construction of a section of comprehensive pipe gallery is completed. 7. A construction method using comprehensive pipe gallery construction equipment according to claim 6, characterized in that, in the step (2), the shrinkage sequence of each oil cylinder of the inner mold (41) is: shrink the left and right mold cylinders first (416), shrink angle mold oil cylinder (417) again, shrink upper and lower mold oil cylinder (415) at last, the shrinkage of side mold oil cylinder (423) and end mold oil cylinder (433) are in no particular order. 8. A construction method using comprehensive pipe gallery construction equipment according to claim 6, characterized in that, in said step (4), when the rear tire assembly (342) travels to 0.5 meters away from the steel frame, it stops walk. 9. A construction method using comprehensive pipe gallery construction equipment according to claim 6, characterized in that, in the step (6), the extension sequence of the oil cylinders of the inner mold (41) is: first extend up and down Die oil cylinder (415), stretch out angle mold oil cylinder (417) again, stretch out left and right sides mold oil cylinder (416) at last, and the stretching out of side mold oil cylinder (423) and end mold oil cylinder (433) are in no particular order.
