Orifice construction device for grouting construction

The utility model relates to the technical field of engineering construction, and discloses an orifice construction device for grouting construction, which comprises a supporting seat, and a fixing pipe is fixedly mounted on the upper surface of the supporting seat. According to the orifice construction device for grouting construction, through cooperative arrangement of a first hand wheel, a rotating rod, a bevel gear, a transmission gear ring, a gear, a threaded rod, a cross folding rod and a fixing plate, a supporting seat base orifice pipe is inserted into an orifice during use, and then a spiral supporting rod is screwed into soil to be fixed by rotating a rotary knob; then, a first hand wheel is shaken to drive a rotating rod and a bevel gear to rotate, and meanwhile, a first threaded rod is driven to rotate through a transmission gear ring and a gear which are meshed, so that a crossed folding rod can be driven to slide along the surface of the first threaded rod, and meanwhile, a fixing plate is pushe
