10. A method of installing a manhole perimeter reinforcement and protection device using the manhole perimeter reinforcement and protection device of claim 1, wherein: it comprises the following steps:
step 1: constructing an inspection well shaft, covering the well mouth of the inspection well by adopting a steel plate when the second masonry brick wall shaft (7) is constructed to the top surface of the roadbed (16), and positioning the center of the inspection well by coordinates;
step 2: constructing a cement stabilized macadam lower base layer (15), locating an inspection well through a total station coordinate after the construction of the cement stabilized macadam lower base layer (15) is completed, finding the inspection well in a reverse excavation mode, breaking a pavement structure layer in the construction range of a shaft of the inspection well, lengthening the pavement structure layer to a second masonry brick wall shaft (7) until the top surface of the cement stabilized macadam lower base layer (15), covering a shaft mouth of the inspection well by adopting a steel plate until maintenance and acceptance are qualified, and starting to prepare for the construction of a cement stabilized macadam upper base layer (14);
step 3: constructing a cement stabilized macadam upper base layer (14), immediately reversely excavating an extension shaft to a position 1cm below the top surface of a coarse-grained asphalt surface layer (13) after the cement stabilized macadam upper base layer (14) is paved and rolled, placing a reinforcement cage at the top of a second masonry brick wall shaft (7), embedding integral high-strength bolts (5) in the reinforcement cage, erecting a template, pouring concrete, curing and forming to complete the forming of a ring beam (4), and after the ring beam (4) is formed, completing the construction of a first masonry brick wall shaft (6) at the top of the ring beam (4), installing a shaft protection device (3) at the moment, immediately paving and flattening the cement stabilized macadam upper base layer (14) in the construction range of the shaft protection device (3) outside the inspection shaft after the installation is completed, covering the well mouth of the inspection shaft, and completing the static pressure compaction and water spraying and curing of the periphery of the shaft;
step 4: after the construction of the cement stabilized macadam upper base layer (14) is completed, curing is finished, penetrating oil is sprayed, coarse-grain asphalt surface layer (13) paving is started, when the temperature of the coarse-grain asphalt surface layer (13) is reduced to below 50 ℃, the adhesive oil is sprayed to perform middle-grain asphalt surface layer (12) paving, after rolling is completed, the middle-grain asphalt surface layer (12) in the range of the well cover support (1) is broken and cleaned in a reverse excavation mode, a screw cap (10) is screwed after the manhole cover support (1) is installed, and finally the paving of the middle-grain asphalt surface layer (12) and the whole fine-grain asphalt surface layer (11) in the range of the well cover support (1) is completed.
