Abstract
The utility model relates to a prevent inspection shaft pit shaft of backing up of sewage, it includes the first straight well section of thick bamboo section (1) that links to each other with well seat tube end its characterized in that the top of first straight well section of thick bamboo section (1) is provided with funnel type pit shaft section (3) the top of funnel type pit shaft section (3) is provided with the type of falling funnel pit shaft section (4) the top of the type of falling funnel pit shaft section (4) is provided with the second straight well section of thick bamboo section (5) that is used for installing the well lid be provided with in funnel type pit shaft section (3) and the type of falling the funnel pit shaft section (4) mild rubber body (6), the diameter of rubber body (6) is greater than the diameter of the type of falling funnel pit shaft section (4) upper end. The utility model discloses change the structure of original pit shaft, the inside rubber body of cooperation pit shaft when the positive surge, through the sealed purpose that prevents the backing up of sewage that reaches of locking between body and the pit shaft, reduces environmental pollution.
Description
Technical field
The utility model relates to pipe fitting manhole technical field, particularly the manhole shaft that pours in down a chimney of a kind of bilge water resisting.
Background technology
Manhole is the ancillary structure for rain sewage vent line, is to be convenient to make regular check on and dredging pipeline, prevents the necessary facility of line clogging.
The manhole of current use generally comprises well seat, pit shaft and well lid, and well seat is used for connecting pipe, and pit shaft is installed on the birdsmouth of well seat, and easy access personnel pass in and out.In use find, if when the current in pipeline are excessive or too urgent, if the imperfect words of the sealing of manhole, sewage outwards can be flowed out by pit shaft, causes environment pollution.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides the manhole shaft that a kind of bilge water resisting pours in down a chimney, and can effectively overflow on ground surface by preventing pollution, affect environment.
The purpose of this utility model is achieved in that the manhole shaft that a kind of bilge water resisting pours in down a chimney, it comprises the first straight wellbore section be connected with well seat birdsmouth, funnel type wellbore section is provided with above the described first straight wellbore section, the wellbore section of falling funnel type is provided with above described funnel type wellbore section, the second straight wellbore section for installing well lid is provided with above the described wellbore section of falling funnel type, in described funnel type wellbore section with the wellbore section of falling funnel type, be provided with soft Rubber inflator, the diameter of Rubber inflator is greater than the diameter of the wellbore section of falling funnel type upper end.
The lower end of the described first straight wellbore section is provided with the watertight rubber circle be sealed and matched with well seat birdsmouth, at upper end and the sheathed watertight rubber circle of well lid link position of the second straight wellbore section.
Compared with prior art, the beneficial effects of the utility model are:
The utility model changes the structure of original pit shaft, coordinates the Rubber inflator of pit shaft inside, when water level rises, is reached the object preventing backing up of sewage by lock sealing between buoyancy aid and pit shaft, reduces environment pollution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein:
First straight wellbore section 1
Watertight rubber circle 2
Funnel type wellbore section 3
The wellbore section of falling funnel type 4
Second straight wellbore section 5
Rubber inflator 6.
Detailed description of the invention
See Fig. 1, the utility model relates to the manhole shaft that a kind of bilge water resisting pours in down a chimney, comprise the first straight wellbore section 1 be connected with well seat birdsmouth, the lower end of the described first straight wellbore section 1 is provided with the watertight rubber circle 2 be sealed and matched with well seat birdsmouth, funnel type wellbore section 3 is provided with above the described first straight wellbore section 1, the wellbore section of falling funnel type 4 is provided with above described funnel type wellbore section 3, funnel type wellbore section 3 adopts arc transition to be connected with the junction of the wellbore section of falling funnel type 4, the second straight wellbore section 5 for installing well lid is provided with above the described wellbore section of falling funnel type 4, watertight rubber circle 2 is arranged with in the upper end of the second straight wellbore section 5 and well lid link position, soft Rubber inflator 6 is provided with in described funnel type wellbore section 3 with the wellbore section of falling funnel type 4, the diameter of Rubber inflator 6 is greater than the diameter of the wellbore section of falling funnel type 4 upper end, after sewage enters pit shaft, Rubber inflator 6 is upwards risen until in the clamping sealing of the upper end of the wellbore section of falling funnel type 4 by funnel type wellbore section 3, prevent sewage from flowing into ground surface and contaminated environment by well lid.
