Tool for assisted construction of anti-subsidence manhole cover asphalt reinforcement layer

Abstract

The invention discloses a tool for assisted construction of an anti-subsidence manhole cover asphalt reinforcement layer, and belongs to the field of municipal construction tools. The tool comprises a hollow cylinder part (3) and a hollow round table part (2), wherein the outer diameter of the bottom surface of the hollow round table part (2) is equal to the outer diameter of the top surface of the hollow cylinder part (3), the bottom surface of the hollow round table part (2) is connected to the top surface of the hollow cylinder part (3), the outer diameter of the top surface of the hollow cylinder part (3) is equal to the inner diameter of a pitshaft, and a handle (1) is fixedly arranged on the hollow round table part (2). According to the present invention, before the asphalt layer is paved, the bottom portion of the hollow cylinder part (3) is placed on the shaft mouth and then the asphalt is paved around the tool and compacted, the tool is pulled out after the asphalt is cooled to the temperature of about 60 DEG C and molded, and the lower portion of the manhole cover is inserted into the pitshaft to perform vibration rolling so as to make the manhole cover and the asphalt reinforcement layer tightly contact, such that the construction process for reinforcing the manhole cover through the asphalt is completed.

Description

technical field [0001] The invention relates to the field of municipal construction tools, in particular to a tool for assisting the construction of an anti-settling manhole cover asphalt reinforcement layer. Background technique [0002] The existing anti-settling inspection well flexible installation mold utilizes the existing anti-settling inspection well seat to remove the outer edge and only the shaft remains. The advantage of this mold is that it can match the inspection well cover and the anti-settling part provided by the manhole cover manufacturer. The disadvantage is that there is a staggered platform between the anti-subsidence well circle part and the lower anti-subsidence part, and it cannot be rolled and compacted during the backfill compaction of coarse and medium-grained asphalt. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides an auxiliary anti-settling manhole cover asphalt reinforcement lay...
