The invention belongs to the technical field of building infrastructures, and particularly relates to a multifunctional protective well lid. The multifunctional protective well lid comprises a prefabricated well bore. A well bore cavity is formed in the prefabricated well bore. The top and the bottom of the prefabricated well bore are of an open structure. A displacement-resistant fixing barrel is arranged in the well bore cavity. The outer wall of the displacement-resistant fixing barrel is attached to the inner wall of the prefabricated well bore. A fixing barrel cavity is arranged in the displacement-resistant fixing barrel. A protrusion part protruding inwards is arranged at the bottom of the displacement-resistant fixing barrel. A falling prevention auxiliary lid body is arranged in the fixing barrel cavity. The edge of the falling prevention auxiliary lid body is located above the protrusion part. A well base is connected with the outer side of the top of the displacement-resistant fixing barrel and comprises supporting plates. The well base is located above the prefabricated well bore. A cement filling hole is formed in the upper surface of the prefabricated well bore. The supporting plates are provided with positioning holes. Fixing rebars are arranged in the positioning holes.
Description
technical field [0001] The invention belongs to the technical field of building infrastructure, and in particular relates to a multifunctional protective manhole cover. Background technique [0002] Our company has built sewers and inspection wells for more than 30 years, and found many defects in the traditional five-proof inspection manhole covers: [0003] 1. Anti-theft, 2. Anti-jumping. Generally, three methods are used: hinge type, iron chain fixed type, and self-cast iron three-point deadbolt fixed type. More than 95% of the existing three types will be damaged. Hinge, lock The tongue is cast iron, and we need to replace 30-50% of the hinges before handing over the work. The reason is that when the manhole cover is opened, the manhole cover is too heavy and the manhole cover will be broken in an instant; It will be broken in an instant, the chain type is fixed, and the fixed end is an expansion bolt, which generally cannot withstand corrosion. [0004] 3. Anti-fallin...
