Abstract
A liftable multi-ring manhole cover comprises a big L-shaped fixed ring, a medium L-shaped fixed ring, a small L-shaped fixed ring, a manhole cover holder, a manhole cover, a supporting rib and supporting bolts; the inner wall of the manhole cover holder is provided with the supporting rib, the L-shaped fixed rings are sequentially nested together, and are jointly mounted on the supporting rib, the manhole cover is mounted on the small L-shaped fixed ring, the annular surface of the supporting rib is provided with evenly distributed bolt holes, the bolt holes are not equipped with the supporting bolts normally unless the pavement is risen, so that rusting can be prevented, and the supporting bolts respectively support and adjust the bottoms of the big L-shaped fixed ring, the medium L-shaped fixed ring and the small L-shaped fixed ring when the pavement is risen. The liftable multi-ring manhole cover has the advantages that: the principle and the structure are simple, and the liftable multi-ring manhole cover is convenient to fabricate and mount; during construction, the lifting of the manhole cover cannot lead to destructive operation, consequently, the construction period can be shortened, and a series of complex construction procedures in the process of pavement construction, such as dismounting of the conventional manhole cover, sporadic construction, plastering, maintenance, material organization and surplus soil removal, are thoroughly changed.
Description
Technical field
The utility model relates to
Background technology
In urban road construction and residential quarters construction, various pipe networks are embedded in underground, therefore various manholes need be set.Like sewage conduct well, feedwater piping well, fire protection pipeline well, heat distribution pipeline well, storm sewer well, gas flue well, communication conduit well or the like.The setting of these wells spreads all in the various roads and community courtyard in city, and its well lid upper surface is concordant with ground, and well lid is retainer plate and concrete surface and asphalt floor is bordered on and fixing dead all round.Municipal administration road surface and garden road surface all will be keeped in repair, overhaul every year, and the road surface that has wants whole thickening to lay.If the road surface does not have the obstacle of various well lids, it will be to accelerate greatly that the integral body on road surface is laid fltting speed.Through the investigation of road pavement laying construction, various pipe wells reorientate construction, account for 2/3rds of total duration of engineering construction, and can't adopt mechanized.
Traditional way is: the piping shaft isolation guardrail is set, the piping shaft removable cover is taken off, remove or the destructive well lid base of removing, owing to all round the fixing difficulty of removing is big, efficiency of construction is very low; According to new pavement design absolute altitude, mend building well wall again to design elevation, reinstall fixing complete well lid base, the maintenance health is to design strength, again road surface pavement.
The construction period of whole engineering is all shared, consuming time by the construction of slight well lid, consumption power, consumptive material.The biggest obstacle that road is repaired again is the dismounting again of well lid, and it has hindered the development of urban construction, and therefore traditional job practices must obtain changing.
The utility model content
The purpose of the utility model is in road repair process again, simplifies the hoisting way of well lid, and the spy provides a kind of lift-type to encircle well lid more.
The utility model provides a kind of lift-type to encircle well lid more, it is characterized in that: described lift-type encircles well lid more and comprises big L type retainer ring 1, middle L type retainer ring 2, little L type retainer ring 3, well lid holder 4, well lid 5, ribs 6, carrying bolt 7;
Wherein: well lid holder 4 is installed in the top of the borehole wall 8 through concrete; Have ribs 6 on the inwall of well lid holder 4, big L type retainer ring 1, middle L type retainer ring 2 and little L type retainer ring 3 are nested together successively, are installed in jointly on the ribs 6; Well lid 5 is installed on the little L type retainer ring 3; On the ring surface of ribs 6, have the bolt hole that is uniformly distributed with, carrying bolt 7 supports big L type retainer ring 1, middle L type retainer ring 2 and little L type retainer ring 3 bottoms respectively.
Described big L type retainer ring 1, middle L type retainer ring 2, total number of little L type retainer ring 3 is 1-5, size is successively decreased successively.
The bolt hole that is uniformly distributed with on the described ribs 6 is 8-40.
When road surfacing, with the 7 adjustment height of the carrying bolt on the ribs 6, jack-up L type retainer ring can rise well lid, simultaneously the height space that rises is tamped with high strength mortar 9, plays firm effect.
The advantage of the utility model:
The described lift-type of the utility model encircles well lid more, and theory structure is simple, and fabrication and installation are convenient, and cost is low; Can not bring destructive operation because of the lifting of well lid during construction, pollution-free, no waste material uses manpower and material resources sparingly, the reduction of erection time, promote efficient, and reduce the road traffic duration of congestion of paving the way and bringing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 encircles well lid road surface scheme of installation first for lift-type more;
Fig. 2 encircles four road surface scheme of installations of well lid for lift-type more;
Among the figure, 10 are road surface first, and 11 is the secondary road surface, and 12 is three road surfaces, and 13 is four road surfaces;
Fig. 3 installs local enlarged diagram for lift-type encircles four road surfaces of well lid more.
