Abstract
The utility model provides an inspection well with a plug-in sleeve, which comprises a well body, wherein a pipeline connection port is formed at the lateral part of the well body, and inspection openings are formed at the top or/and the bottom of the well body. The inspection well is characterized in that the plug-in sleeve is arranged at the pipeline connection port at the lateral part of the well body and formed by an inner sleeve, an outer sleeve and an annular groove positioned between the inner sleeve and the outer sleeve. The inspection well can be connected with the a horizontal pipeline conveniently and quickly, so that not only is the labor intensity greatly lowered, but also the working efficiency is improved; the contact area at the connection of pipelines is increased, so as to considerably improve the sealing effect of the connection; and by the use of a sealing strip or a thermal contraction belt, the sealing effect is further enhanced. The inspection well has the advantages of simple structure, convenience and quickness in installation and superior sealing performance.
Description
Technical field
The utility model relates to a kind of manhole, and particularly a kind of manhole with the cover of pegging graft belongs to pipe joint Seal Design technical field.
Background technology
As various network of underground such as the drainage pipeline networks of communal facility, waterline network, cable communication pipelines, be the important component part of urban construction.For network of underground, connection between the pipeline and sealing are very important, in case the pollution that appearance is leaked, seepage will cause underground water, soil, problems such as the waste of water resource.At present the flange and the hold-down screw that are connected mostly by the joint between pipeline and the manhole connects, and seals by the rubber seal on the flange.Because flange connects need be by manually being spirally connected, therefore installation workload is quite big, labour intensity is very high, especially for large diameter pipeline, nearly tens on the bolt of junction, even up to a hundred, its efficient of such installation is very low, brings very big trouble for the construction and the maintenance of network of underground.In use simultaneously, can influence the bearing strength of junction, network of underground is leaked after construction is finished, bring very big trouble for the maintenance and the construction of network of underground because of the sedimentation of soil matrix or pipe network.Be subjected to the restriction of material in addition, sealing ring is generally rubber product, be generally its application life 10 years, and the application life of pipe network is more than at least 50 years, this has just caused pipeline asynchronous with sealing ring application life, passing sealing ring in time is aging gradually, thereby reduces sealing performance, increases potential safety hazard.Therefore be necessary prior art is improved.
Summary of the invention
Is connected seepage, the leakage problem that brings for solving between existing manhole and the pipeline by bell socket, problem such as sealing exists aging, and potential safety hazard is comparatively obvious, it is a kind of with the manhole of pegging graft and overlapping that the utility model provides.
The utility model is finished by following technical proposal: a kind of manhole with the cover of pegging graft, comprise that its sidepiece establishes pipeline connection port, its top is or/and the well body of inspection hole is established in the bottom, the pipeline connection port that it is characterized in that well side portion is provided with the cover of pegging graft, this grafting cover is made of interior cover, overcoat and the cannelure between inside and outside cover, so that when this manhole is connected with horizontal pipe, only pipe end need be inserted in the cannelure between the inside and outside cover, twine shrink belt again, can connect and seal.
The cover external diameter is less than the internal diameter of pipeline end in described, and outer casing internal diameter is greater than the external diameter of pipeline end, places cannelure between the inside and outside cover to make things convenient for the pipeline end.
Described overcoat length is less than interior cover length, with insertion and the winding shrink belt that makes things convenient for the pipeline end.
Described overcoat length is greater than interior cover length, with insertion and the winding shrink belt that makes things convenient for the pipeline end.
The utlity model has following advantage and effect: the inserting mode that adopts such scheme, can easily horizontal pipe fast be connected with manhole, not only greatly reduce labour intensity, but also improved operating efficiency, but also increased the contact area of pipeline junction, greatly improved the sealing effectiveness of junction, the use of fitted seal bar or shrink belt again, further reinforcement sealing effectiveness, be a kind of simple in structure, manhole easy for installation, quick, that sealing performance is superior.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As Fig. 1, the manhole that the band that the utility model provides is pegged graft and overlapped, comprise that its sidepiece establishes pipeline connection port 3, the well body 1 of inspection hole 2,9 is established in its top and bottom, wherein the pipeline connection port 3 of well body 1 sidepiece is provided with the cover 4 of pegging graft, and this graftings is overlapped 4 and is made of interior cover 6, overcoat 5 and the cannelure between inside and outside cover 8; Cover 6 external diameters are less than the internal diameter of pipeline 7 ends in described, and overcoat 5 internal diameters are greater than the external diameter of pipeline 7 ends; Described overcoat 5 length are less than interior cover 6 length, so that this manhole when being connected with horizontal pipe 7, only needs pipeline 7 ends are inserted in the cannelure 8 between the inside and outside cover, twine shrink belt again, can connect and seal.
Claims (4)
1. manhole with the cover of pegging graft, comprise that its sidepiece establishes pipeline connection port, its top is characterized in that the pipeline connection port of well side portion is provided with the cover of pegging graft or/and the well body of inspection hole is established in the bottom, and this grafting cover is made of interior cover, overcoat and the cannelure between inside and outside cover.
2. the manhole that band according to claim 1 is pegged graft and overlapped is characterized in that the internal diameter of described interior cover external diameter less than the pipeline end, and outer casing internal diameter is greater than the external diameter of pipeline end.
3. the manhole that band according to claim 1 is pegged graft and overlapped is characterized in that described overcoat length is less than interior cover length.
4. the manhole that band according to claim 1 is pegged graft and overlapped is characterized in that described overcoat length is greater than interior cover length.
