(3) cage, well seat are provided with cross reinforcing and vertical strengthening ribs, and infall has arc reinforcement fillet, strengthen overall compressive resistance, quality is high, and physical life is long.
(4) internal diameter of cage is 1.1-1.2 times of well seat internal diameter, can, as manhole, facilitate procuratorial work to keep in repair, and blowdown convenience and high-efficiency.
(5) pipe joint circumference is uniformly distributed, and ensure well seat wall uniform force, draining facilitates smooth and easy.
(6) outward flange of inner-outer sleeve gripper shoe is positioned at pipe inner sleeve outward flange 1/1 to four/3rd pipe inner sleeve length place, ensures external pipe and is connected between pipe inner sleeve fully reliably.Pipe inner sleeve outward flange is positioned at pipe overcoat outward flange 1/1 to four/3rd pipe its length place.External pipe is facilitated to be sheathed between pipe inner sleeve and pipe overcoat.
Accompanying drawing explanation
Fig. 1 is two structural representations of procuratorial work well;
Fig. 2 is the sectional view of pipe joint.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the hermetically sealed manhole of a kind of mouth of pipe, comprises cage 1, well seat 2, base 3 and 3 circumferences and is arranged at pipe joint 4 on well seat wall uniformly.Cage 1, well seat 2 are provided with cross reinforcing and vertical strengthening ribs, and cross reinforcing and vertical strengthening ribs intersect mutually, and infall has arc reinforcement fillet.Strengthen overall compressive resistance, quality is high, and physical life is long.Preferably, the internal diameter of cage 1 is 1.12 times of well seat 2 internal diameter, can, as manhole, facilitate procuratorial work to keep in repair, and blowdown convenience and high-efficiency.
