Abstract
The utility model relates to a wellhead sealed inspection well comprising a plastic well lid, a plastic cover base positioned at the lower end of the well lid and a plastic pit shaft, wherein the cover base and the pit shaft adopt sealed bonding, a short cylinder body is arranged below the well lid and forms an entirety together with the well lid, the external diameter of the short cylinder body is smaller than the internal diameter of the pit shaft, and the well lid and the pit shaft are connected in a sealed manner via an O-shaped rubber seal ring sleeved outside the well lid. The utility model not only facilitates the inspection, but also satisfies the sealing requirement, thereby being applicable to inspection wells of various special pipeline systems in the architecture and municipal engineering, in particular to building indoor pipeline systems and other pipeline systems required to be sealed by process, and provide matched inspection wells for the sealed pipeline systems.
Description
Technical field
The utility model belongs to manhole commonly used in building and the municipal engineering, particularly relates to a kind of manhole of well head sealing.
Background technology
In the prior art, in building and the municipal engineering a kind of plastic draining manhole is arranged, constitute, all adopt plastic material to make by well lid, cage, the pit shaft that is connected with inlet and outlet piping.But well head is not made closed type, and well lid just covers on well head, and obturation effect is relatively poor, be prone to the interior liquid of well during use and overflow, or the outer liquid of well flows into the phenomenon in the well.Such as: be used for indoorly during, owing to rainfall has rainwater to overflow greatly, influence surrounding environment often as rainwater inspection well; When being used for outdoor manhole as process pipe, then there being rainwater to infiltrate in the well and influencing system in the well.Thereby be necessary on existing basis, to be improved, avoid well external system generation phase mutual interference in the well.
Summary of the invention
Technical problem to be solved in the utility model provides the sealed manhole of a kind of well head, and is poor with the obturation effect that solves manhole in the prior art, be prone to the interior liquid of well during use and overflow, or the outer liquid of well flows into the problem in the well.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of well head sealed manhole, form by plastics system well lid, the plastics system cage that is positioned at the well lid lower end, plastics system pit shaft, cage and pit shaft are bonding for sealing, well lid is down with a short cylinder, well lid and short cylinder are an integral body, and the external diameter of this short cylinder is less than the internal diameter of pit shaft.
Well lid and pit shaft are tightly connected by being enclosed within the outer O shape rubber seal of well lid.
Beneficial effect
The utility model has been strengthened the obturation effect of manhole, prevents that liquid overflows in the well, or liquid flows into the interior phenomenon generation of well outside the well, has avoided well external system generation phase mutual interference in the well.Uncapping when checking use, it is all very convenient to close lid.
Description of drawings
Fig. 1 is a sectional drawing of the present utility model.
Wherein: 1-well lid, 2-cage, 3-O shape rubber seal, 4-pit shaft.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The sealed manhole of a kind of well head, be made up of plastics system well lid 1, the plastics system cage 2 that is positioned at well lid 1 lower end, plastics system pit shaft 4, cage 2 is bonding for sealing with pit shaft 4, and well lid has a short cylinder 1 time, well lid and short cylinder are an integral body, and the external diameter of this short cylinder is less than the internal diameter of pit shaft 4.Well lid 1 is tightly connected by the O shape rubber seal 3 that is enclosed within outside the well lid 1 with pit shaft 4.
As shown in Figure 1, when the utility model is installed, earlier cage 2 is buckled on the pit shaft 4, it is bonding to form sealing, and the short cylinder under the well lid 1 is put O shape rubber seal 3 outward, at last well lid 1 is buckled on the cage 2, and make well lid 1 attached short cylinder stretch into certain distance in the pit shaft 4, make well lid 1 equal, O shape rubber seal 3 is arranged between well lid 1 and the pit shaft 4, form sealing with cage 2.
Claims (2)
1. sealed manhole of well head, comprise plastics system well lid (1), be positioned at plastics system cage (2), the plastics system pit shaft (4) of well lid (1) lower end, cage (2) is bonding for sealing with pit shaft (4), it is characterized in that: described well lid (1) is down with a short cylinder, well lid and short cylinder are an integral body, and the external diameter of this short cylinder is less than the internal diameter of pit shaft (4).
