Description
Technical field
The utility model relates to a kind of manhole, particularly a kind of contour structures wall manhole.
Background technology
Though the manhole of China's macromolecular material is more late than abroad starting to walk, each show his special prowess as The Eight Immortals cross the sea for the manhole of various shape, develops rapidly like the mushrooms after rain.Be all cylindrical shape bottom existing manhole, manhole only relies on the circular arc of cylinder as support, and the middle part of cylinder lacks support, the axial load existing defects of manhole.
Utility model content
The technical problems to be solved in the utility model is: in order to solve manhole axial load problem, and the utility model provides a kind of contour structures wall manhole.
The utility model solves the technical scheme that its technical problem adopts: a kind of contour structures wall manhole, comprise pit shaft and be arranged on first in pit shaft side wall and import mouth, the second remittance mouth, the 3rd remittance mouth and flow export, described 3rd remittance mouth and flow export are oppositely arranged, described first imports mouth for vertically to import mouth, described second imports mouth and the 3rd imports mouth for laterally importing mouth, described wellbore bottom outer wall is provided with reinforcing rib, and described reinforcing rib is the most extension of wellbore bottom.
Described reinforcing rib comprises and imports mouth to the parallel or vertical horizontal bar of the flow direction of flow export and vertical muscle along the 3rd.
Described vertical muscle extends to pit shaft side wall from wellbore bottom.
Described pit shaft top has bellmouth, and described vertical muscle extends to from wellbore bottom bottom the bellmouth of pit shaft side wall.
Described second imports mouth and the 3rd imports vertical connecting portion between mouth, and/or the described second vertical connecting portion imported between mouth and flow export is provided with angle muscle, and described angle muscle and described horizontal bar and vertical muscle all tilt.
All same plane is extended outwardly at the horizontal bar of wellbore bottom, vertical muscle and angle muscle.
Described shaft in wall is smooth.
Described first imports mouth, the second remittance mouth, the 3rd imports mouth and is arc transition with the position that flow export is connected with described pit shaft inner chamber.
The beneficial effects of the utility model are, contour structures wall manhole of the present utility model, and wellbore bottom is supported by reinforcing rib, and vertical muscle extends to pit shaft side wall, improves the axial load of manhole.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the optimum embodiment of contour structures wall manhole of the present utility model.
Fig. 2 is the structural representation of the optimum embodiment of contour structures wall manhole of the present utility model.
Fig. 3 is the top view figure of contour structures wall manhole of the present utility model.
Fig. 4 is the sectional view of contour structures wall manhole of the present utility model.
In figure 1, pit shaft, 11, first imports mouth, and 12, second imports mouth, and the 13, the 3rd imports mouth, 14, flow export, 15, horizontal bar, 16, vertical muscle, 17, angle muscle, 2, bellmouth, 3, guiding gutter, 4, dredging circular arc.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Figure 1-4, Fig. 1 is the bottom-up structural representation of manhole.A kind of contour structures wall manhole of the present utility model, comprise pit shaft 1 and be arranged on first on pit shaft 1 sidewall and import mouth 11, second imports mouth 12, 3rd imports mouth 13 and flow export 14, described 3rd imports mouth 13 is oppositely arranged with flow export 14, described first imports mouth 11 for vertically to import mouth, described second imports mouth 12 and the 3rd imports mouth 13 for laterally importing mouth, described pit shaft 1 bottom outer wall is provided with reinforcing rib, described reinforcing rib is the most extension bottom pit shaft 1, namely described reinforcing rib is from the height of outward extending height bottom pit shaft 1 higher than other positions bottom described pit shaft 1.
Described reinforcing rib comprises and imports mouth 13 to the parallel or vertical horizontal bar 15 of the flow direction of flow export 14 and vertical muscle 16 along the 3rd.Described second imports the vertical connecting portion between mouth 12 and the 3rd remittance mouth 13, and/or the described second vertical connecting portion imported between mouth 12 and flow export 14 is provided with angle muscle 17, and described angle muscle 17 all tilts with described horizontal bar 15 and vertical muscle 16.
Described pit shaft 1 top has bellmouth 2, and described vertical muscle 16 extends to bottom the bellmouth 2 of pit shaft 1 sidewall bottom pit shaft 1.Horizontal bar 15 bottom pit shaft 1, vertical muscle 16 and angle muscle 17 all extend outwardly into same plane.
Described pit shaft 1 inner wall smooth, described first imports mouth 11, second remittance mouth 12, the 3rd remittance mouth 13 is arc transition with the position that flow export 14 is connected with described pit shaft 1 inner chamber.Pit shaft 1 intracavity bottom guiding gutter 3 turning is provided with arc transition can make current unimpeded, and the top bellmouth of pit shaft 1 and the 3rd imports to be provided with between mouth 13 and flow export 14 dredges the discrepancy that circular arc 4 is convenient to clear and coherent instrument.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
