Dense pipeline type tube well plate component

The invention discloses a dense pipeline type tube well plate component, and belongs to the technical field of pipeline shafts, the dense pipeline type tube well plate component comprises a tube well prefabricated plate arranged at the top of a tube well reserved hole, and a plurality of positioning through holes are formed in the top surface of the tube well prefabricated plate; the device further comprises a supporting screw rod, a supporting screw sleeve, a floor drain butt joint pipe, an extrusion positioning mechanism, a rotating rod, a synchronous rotating mechanism, a positioning block and an insertion positioning mechanism. Through mutual cooperation of an extrusion positioning mechanism, a synchronous rotating mechanism, a transmission part and a pulling part, the bottom face of the tube well prefabricated slab is automatically subjected to movable limiting of a limiting block, rotary limiting of a rotating rod and precise positioning operation of a supporting screw rod and a supporting thread sleeve
