Abstract
The utility model relates to a kind of manhole, and particularly a kind of rainwater sinks mud manhole.Comprise well lid, pit shaft, observation tube, arm, have concrete bearing ring to be connected between well lid and pit shaft, pit shaft is arranged with observation tube, and arm has been crossed in the bottom of observation tube; Described observation tube is a circular vertical tube.The purpose of this utility model is to provide a kind of for convenience detach, cleaning, and the rainwater of good seal performance sinks mud manhole.
Description
Technical field
The utility model design review (check) (DR) well, particularly a kind of rainwater sink mud manhole.
Background technology
Rainwater inspection well generally connects rainwater mud discharging pipeline, for the ancillary structure for maintainer people or equipment inspection, removing foreign matter, be a kind ofly be convenient to make regular check on, dredging pipeline and prevent the necessary facility of line clogging.Sewage inspection well is for checking and cleaning pipeline and the inspection shaft set up on sewerage system.Also work the draught effect connecting pipeline section and pipe-line system simultaneously.Between adjacent two wells, pipeline section point-blank, therefore, all should need to arrange manhole in conduit section change place, gradient change place, intersection, elevation change place, long straight line pipeline section also needs subsection setup manhole.When present, rainwater is catch-basin, and sewage is sink hole, and often cause construction area large, necessary is many, is inconvenient to dismantle, and is inconvenient to use.
Utility model summary of the invention
In view of above-mentioned the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of for convenience detach, cleaning, and the rainwater of good seal performance sinks mud manhole.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of rainwater sinks mud manhole, and comprise well lid, pit shaft, observation tube, arm, have concrete bearing ring to be connected between well lid and pit shaft, pit shaft is arranged with observation tube, and arm has been crossed in the bottom of observation tube; Described observation tube is a circular vertical tube.
Further, pit shaft and observation tube engaging.
Further, the external diameter of pit shaft is greater than the external diameter of observation tube.
Further, the inwall of pit shaft, observation tube and arm is smooth inwall.
The beneficial effects of the utility model: formed by engaging between well lid and observation tube, existing very strong seal again can be for convenience detach, and have concrete bearing ring between well casing and well lid, prevents well casing to be out of shape, effectively prevent effluent seepage.Structure of the present utility model is simple, without the need to brick, can be made of plastic, and meet " use brick manhole about restriction, promote the use of plastic inspection well " of promoting in the industry at present.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 is well lid, and 2 is concrete pressure coil, and 3 is pit shaft, and 4 is arm, and 5 is observation tube.
Detailed description of the invention
Connection with figures and embodiment are described further the utility model.
See accompanying drawing 1, a kind of rainwater sinks mud manhole, and comprise well lid, pit shaft, observation tube, arm, have concrete bearing ring to be connected between well lid and pit shaft, pit shaft is arranged with observation tube, and arm has been crossed in the bottom of observation tube; Described observation tube is a circular vertical tube.
Further, pit shaft and observation tube engaging.
Further, the external diameter of pit shaft is greater than the external diameter of observation tube.
Further, the inwall of pit shaft, observation tube and arm is smooth inwall.
