Abstract
The invention discloses an eccentric inspection well base. The eccentric inspection well base comprises a base body, a first joint and a second joint; the first joint extends from one end of the base body; the second joint extends from the other end of the base body; a first supporting portion is arranged under the first joint; a second supporting portion is arranged under the second joint; the base body comprises a horizontal tubular body and a vertical tubular body which is arranged above the horizontal tubular body; the interior of the horizontal tubular body is communicated with the interior of the vertical tubular body; the center of the first joint is provided with a first circular hole; the center of the second joint is provided with a second circular hole; the diameter of the first circular hole is smaller than that of the second circular hole; the first circular hole is an eccentric circular hole; the second circular hole is a concentric circular hole; the center of the first circular hole is formed towards the direction of the first supporting portion in an inclined mode and accordingly the sewage in the base body can flow out smoothly and the choked flow can be avoided.
Description
Technical field
The present invention relates to a kind of manhole, relate in particular to a kind of eccentric manhole base.
Background technology
Manhole is basic, the crucial ancillary structure of in urban drainage system, mainly be arranged on sewer direction turning point, change place of the sewer gradient, pipe duct section, basis, interface change Chu, pipe duct intersection, straight line pipe duct every certain distance and special purpose (as drop, hold back, overflow etc. located), for realizing the connection between sewer, and facilitate pipe duct maintenance.Described manhole is comprised of shaft bottom seat, pit shaft, well lid or protection cage and manhole accessory.Manhole base of the prior art generally comprises: base body and be installed on the jointing at base body two ends, the top of described base body is provided with for being communicated with the opening of pit shaft.Described jointing arranges in a tubular form, in work progress, often need the jointing at base body two ends to connect respectively the pipe of two different-diameters, therefore, the perforate that just need to offer respectively different-diameter on two jointings, in prior art, perforate is generally concentric circle holes (center of circle that is the center of circle of perforate and the cylindrical of jointing overlaps), this will cause a problem, because opening diameter is on one side large, opening diameter is on one side little, if guarantee when design, the large one side drainage flow of opening diameter is talked about smoothly will cause one side that opening diameter is little to produce choked flow.
Therefore be necessary to provide a kind of eccentric manhole base solving the problems of the technologies described above.
Summary of the invention
Technical problem to be solved by this invention is: a kind of simple in structure, eccentric manhole base that drainage flow rate is good is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of eccentric manhole base, comprise: base body, the first jointing extending from base body one end and the second jointing extending from the base body other end, described the first jointing below is provided with the first support portion, described the second jointing below is provided with the second support portion, described base body comprises Horizontal tubular body and is arranged at the vertical tubular body of Horizontal tubular body top, the inside of described Horizontal tubular body is connected with the inside of vertical tubular body, the central authorities of described the first jointing offer the first circular hole, the central authorities of described the second jointing offer the second circular hole, the diameter of described the first circular hole is less than the diameter of the second circular hole, described the first circular hole is eccentric circular hole, described the second circular hole is concentric circle holes, the center of circle of described the first circular hole is towards the direction biasing of the first support portion.
As a kind of preferred technical scheme, described the first jointing is the setting of different wall tubulose, the center of circle of the first jointing cylindrical is departed from the center of circle of described the first circular hole, described the second jointing is the setting of identical wall thickness tubulose, and the center of circle of the center of circle of described the second circular hole and the second jointing cylindrical coincides.
As a kind of preferred technical scheme, the base wall of described the first jointing is thin, top wall thickness.
As a kind of preferred technical scheme, on described Horizontal tubular body and vertical tubular body, be equipped with several reinforcing ribs.
As a kind of preferred technical scheme, described eccentric manhole base is made of plastics.
The invention has the beneficial effects as follows: the present invention is by being designed to downward eccentric circular hole by the less perforate of jointing interior diameter, the perforate that diameter is larger is designed to concentric circle holes, thereby the intrinsic sewage of base can be flowed out from two ends comparatively smoothly, avoid occurring choked flow phenomenon.
