Underground pipe network inspection well concrete component and rapid well sinking method thereof

The invention discloses an underground pipe network inspection well concrete component and a rapid well sinking method of the component. The underground pipe network inspection well concrete component comprises a concrete upper neck cylinder part, a concrete middle segment part and a concrete base component. A cylinder opening of the concrete upper neck cylinder part is matched with a concrete well cover; the concrete middle segment part is arranged between the concrete upper neck cylinder part and the concrete base component and is inserted and connected with the concrete upper neck cylinder part and the concrete base component through sealing parts and wedge openings to form an inspection well. The rapid well sinking method of the component comprises the steps of performing excavation, taking soil, sinking well, assembling parts, and connecting the inspection well with a pipeline. Inspection well assembling parts are prefabricated in a manufacturing site, concrete casting or well building through bricking is not required to be carried out in the construction site, and the field construction time is greatly shortened; the assembled type well sinking method is adopted by the inspection well, soil taking and well sinking are carried out at the same time, soil taking is carried out in the well, and the ground foundation disturbance is reduced; enclosure of steel plate piles or timber piles is not needed, the construction speed is high, the working efficiency is high, and the cost is low. The leakage and corrosion prevention performance of the inspection well is improved through a corrosion-prevention lining of the component.
