Abstract

The invention discloses a connection structure of a well base and a pitshaft of an inspection well. The connection structure comprises the well base, the pitshaft and an electric melt arranged at the connection part between the well base and the pitshaft; and the electric melt comprises an electric fuse, plastic wrapped at the outer side of the electric fuse and a wiring terminal connected with the electric melt, the upper side of the well base is provided with an open hole which is matched with the pitshaft, the inner side surface of the electric melt is in contact with the outer side surface of the pitshaft, and the outer side surface of the electric melt is in contact with the hole wall of the open hole of the well base. The connection structure disclosed by the invention is welded without using a welding gun and preparing a welding rod welding gun and is convenient to carry.

Description

technical field [0001] The invention relates to a connection structure between an inspection well base and a shaft. Background technique [0002] The inspection well is used in the outlets, turns, branches, drops and other places of pipelines such as sewage, drainage or wiring, for inspection and maintenance or dredging and cleaning. The inspection well is composed of a well base, a shaft, a well cover or a protective cover seat and inspection well accessories. In the prior art, the shaft of the inspection well is generally connected to the base of the well by welding, but the disadvantage is that it is inconvenient to carry because welding rods and torches are required. [0003] Therefore, it is necessary to provide a connection structure between the inspection well base and the wellbore to solve the above technical problems. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a convenient and fast connection stru...
