Eccentric inspection well base

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 [0001] The invention relates to an inspection well, in particular to an eccentric inspection well base. Background technique [0002] The inspection well is a basic and key subsidiary structure in the urban drainage system. It is mainly installed at the turning point of the direction of the drainage pipe, the slope change of the drainage pipe, the section of the pipe, the foundation, the interface change, the intersection of the pipe, the straight line At certain distances on the pipes and channels and for special purposes (such as water drop, interception, overflow, etc.), it is used to realize the connection between drainage pipes and channels, and to facilitate the maintenance of pipes and channels. The inspection well is composed of a well base, a shaft, a well cover or a protective cover seat and inspection well accessories. The inspection well base in the prior art generally includes: a base body and connection joints installed at both ends of the base...

AI Technical Summary

Problems solved by technology

The connecting joint is arranged in a tubular shape. During the construction process, the connecting joints at both ends of the base body are often required to connect two pipes of different diameters respectively. Therefore, openings of different diameters need to be provided on the two connecting joints. In technology, the openings are generally concentric holes (that is, the center of the opening coincides with the center of the outer circle of the connecting joint), which will cause a problem, because the diameter of the opening on one side is large, and the diameter of the opening on the other side is small. If the design ensures that the sewage flows smoothly on the side with the larger hole diameter, it will cause flow resistance on the side with the smaller hole diameter.
