Abstract
The present invention relates to the manhole shaft that a kind of bilge water resisting pours in down a chimney, it is characterised in that it includes the first straight wellbore section being connected with well seat birdsmouth（1）, in the described first straight wellbore section（1）Top be provided with funnel type wellbore section（3）, in the funnel type wellbore section（3）Top be provided with the wellbore section of falling funnel type（4）, in the wellbore section of falling funnel type（4）Top be provided with the second straight wellbore section for installing well lid（5）, in the funnel type wellbore section（3）With the wellbore section of falling funnel type（4）Inside it is provided with the Rubber inflator of softness（6）, Rubber inflator（6）Diameter be more than the wellbore section of falling funnel type（4）The diameter of upper end.The present invention changes the structure of original pit shaft, coordinates the Rubber inflator inside pit shaft, when water level rises, the purpose for preventing backing up of sewage is reached by lock sealing between floating body and pit shaft, is reduced environmental pollution.
Description
Technical field
The present invention relates to pipe fitting inspection shaft technical field, manhole shaft that more particularly to a kind of bilge water resisting pours in down a chimney.
Background technology
Inspection shaft is the auxiliary construction for rain sewage vent line, is easy for inspecting periodically and dredging pipeline, prevents the necessary facility of line clogging.
The inspection shaft used at present 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, easy access personnel disengaging.Find in use, if in the case that the current in pipeline are excessive or too urgent, if the sealing of inspection shaft is imperfect, sewage can be flowed outwardly by pit shaft, cause environmental pollution.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided the manhole shaft that a kind of bilge water resisting pours in down a chimney, effectively can prevent pollution from overflowing on ground surface, influence environment.
The object of the present invention is achieved like this：The manhole shaft that a kind of bilge water resisting pours in down a chimney, it includes the first straight wellbore section being 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 the funnel type wellbore section, the second straight wellbore section for installing well lid is provided with above the wellbore section of falling funnel type, the Rubber inflator of softness is provided with the funnel type wellbore section and the wellbore section of falling funnel type, the diameter of Rubber inflator is more than the diameter of the wellbore section of falling funnel type upper end.
The watertight rubber circle coordinated with the sealing of well seat birdsmouth is provided with the lower end of the described first straight wellbore section, watertight rubber circle is arranged in the upper end of the second straight wellbore section and well lid link position.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention changes the structure of original pit shaft, coordinates the Rubber inflator inside pit shaft, when water level rises, the purpose for preventing backing up of sewage is reached by lock sealing between floating body and pit shaft, is reduced environmental pollution.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
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.
Embodiment
Referring to Fig. 1,The present invention relates to the manhole shaft that a kind of bilge water resisting pours in down a chimney,Including the first straight wellbore section 1 being connected with well seat birdsmouth,The watertight rubber circle 2 coordinated with the sealing of well seat birdsmouth is provided with the lower end of the described first straight wellbore section 1,The top of described first straight wellbore section 1 is provided with funnel type wellbore section 3,The top of the funnel type wellbore section 3 is provided with the wellbore section of falling funnel type 4,Funnel type wellbore section 3 is connected with the junction of the wellbore section of falling funnel type 4 using arc transition,The second straight wellbore section 5 for installing well lid is provided with the top of the wellbore section of falling funnel type 4,Watertight rubber circle 2 is arranged with the upper end of the second straight wellbore section 5 and well lid link position,The Rubber inflator 6 of softness is provided with the funnel type wellbore section 3 and the wellbore section of falling funnel type 4,The diameter of Rubber inflator 6 is more than the diameter of the upper end of the wellbore section of falling funnel type 4,After sewage enters pit shaft,Rubber inflator 6 is raised above by funnel type wellbore section 3 until in the upper end clamping sealing of the wellbore section of falling funnel type 4,Prevent sewage from flowing into ground surface by well lid and polluting environment.
