Description
Technical field
The utility model relates to a kind of pit shaft that is quick, reliable in quality of constructing, and particularly relates to the precast concrete pit shaft used in a kind of urban road manhole construction operation.
Background technology
At present, along with the development of urban road construction, urban road underground utilities are more, existing serious at the breakage of manhole well head, sinking, walling crib, well lid Loss, more for driving, pedestrains safety hidden danger.Thus make manhole construction quality more and more important in urban road construction.Once cannot complete at urban road construction process check well, well room, pit shaft, walling crib, well lid, must carry out with road construction simultaneously.In prior art, adopt building block or cast-in-place pit shaft cannot be open to traffic fast with urban road again and merge mutually, be just open to traffic when concrete strength does not reach, cause the early stage very cracky of concrete, durability is low, causes walling crib, well lid comes off loss.
Summary of the invention
It is higher that the purpose of this utility model is to propose a kind of work efficiency, can directly install and use, the urban road manhole precast concrete pit shaft that intensity is high.
The purpose of this utility model is achieved in that urban road manhole precast concrete pit shaft, comprise cylindrical shell, described cylindrical shell is the cavity cylinder that upper and lower side is uncovered, the reinforcing rib distributed axisymmetricly is prefabricated with in cylindrical shell, described reinforcing rib upper end exposure is in cylindrical shell upper port, seat ring is prefabricated with in cylindrical shell lower port side, cylindrical shell on the downside of seat ring is inserting section, cylindrical shell upper port outer stretches out formation manhole cover base, well lid is connected with manhole cover base by fast setting cement, described cylinder body outer wall offers tension groove.
Owing to implementing technique scheme, the utility model is simple, quick at construction urban road in-site installation.The raising of prefabricated pit shaft concrete strength can solve the slump of manhole well head, damaged shortcoming, reaches the object be open to traffic in advance of urban road duration.The fixing safety that can ensure driving, pedestrian of walling crib.
Accompanying drawing illustrates: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is urban road manhole precast concrete shaft structure schematic diagram.
Legend: 1. manhole cover base, 2. cylindrical shell, 3. reinforcing rib, 4. tension groove, 5. seat ring, 6. well room.
Detailed description of the invention:
The utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment
:as shown in Figure 1, urban road manhole precast concrete pit shaft comprises cylindrical shell 2, described cylindrical shell 2 is the cavity cylinder that upper and lower side is uncovered, the reinforcing rib 3 distributed axisymmetricly is prefabricated with in cylindrical shell 2, described reinforcing rib 3 upper end exposure, in cylindrical shell 2 upper port, is prefabricated with seat ring 5 in cylindrical shell 2 lower port side, and the cylindrical shell 2 on the downside of seat ring 5 is inserting section, cylindrical shell 2 upper port outer stretches out and forms manhole cover base 1, and well lid is connected with manhole cover base 1 by fast setting cement.Described cylindrical shell 2 outer wall offers tension groove 4, and when installing pit shaft, after around backfill pit shaft, tension groove 4 can be combined closely with backfilling material, pit shaft 2 and backfilling material is connected as a single entity, strengthens its compressive strength.
Described manhole cover base 1 inner port horn mouth, described manhole cover base 1 upper surface evenly offers striped, is conducive to being combined with fast setting cement.
Described tension groove 4 is coherent thread groove.
Described cylindrical shell 2 outer wall offers tension groove 4 along its circumference equi-spaced apart, and described tension groove 4 is closed annular.
During use, first excavate cement stabilizing layer, reach the condition possessing and install pit shaft, and clean out pit shaft 2 contact surface.The height of pit shaft 2 be well seat connect pit shaft bellmouth bottom to the height on design road surface, then deduct the thickness of walling crib.Pit shaft 2 is installed and is kept vertical.Pit shaft 2 and well lid adopt fast setting cement to be connected.Install pit shaft, around backfill pit shaft 2, backfilling material adopts 5% cement stabilized soil.Compacting adopts the compacting of vibration tamping machine, and degree of compaction reaches 95%.Carry out the work of road asphalt concrete speading, abolish cutting optimal and middle surface layer bituminous concrete and walling crib and well lid are installed.Walling crib and reinforcing rib 3 grafting, after grafting, reinforcing rib 3 still exposure, in walling crib upper end, then pounds curved reinforcing rib 3, makes walling crib and pit shaft 2 compact siro spinning technology.Pave upper layer bituminous concrete, the strict planeness controlling road surface and manhole.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
