Abstract

The utility model discloses a pipe, and particularly provides a well base of an inspection well for a community. The well base of the inspection well for the community can reduce the influence of underground water buoyancy. The well base comprises a well chamber bell end and a well body. The well chamber bell end is formed in the upper end of the well body, drain holes are formed in the well body, and the distance between the drain holes and the bottom of the well body ranges from 6mm to 40mm. Due to the fact that the drain holes are formed in the bottom of the well body, when the level of underground water rises, water can enter a cavity in the bottom of the well body through the drain holes, buoyancy acting on the well body is reduced, and then buckling deformation of an installed pipeline and the well base is avoided. Perpendicular reinforcing ribs can be arranged on the outer wall of the well body, protruding deformation generated when the well body is affected by axial loads is avoided, the water leakage phenomenon caused by deformation is avoided, and safety performance can be greatly improved.

Description

Manhole well seat for community

Technical field

The utility model relates to a kind of pipe fitting, manhole well seat for especially a kind of community.

Background technology

Plastic inspection well is requisite connector in drainage pipe, manhole is commonly called as " inspection shaft ", generally be located at that drainage pipe intersection, turning, caliber or the gradient change, locate at a certain distance on drop place and straight line pipeline section, be convenient to make regular check on, the draining ancillary structure of clean and dredging pipeline.Wherein crucial well seat partly adopts once injection moulding, reaches the connection that changes caliber and angle with accessories such as reducer union, variable angle joint and sealing rings.The supporting well lid of developing injection mo(u)lding of manhole, pit shaft, well seat, pavement loading acts on around manhole by well lid, well seat, avoided the destruction of pavement loading to manhole, cage has the function fluctuating, the height that can initiatively adapt to road surface changes, pit shaft adopts special-purpose pit shaft simultaneously, can, according to on-the-spot depth of burying intercepting respective length, have very large flexibility.Pit shaft, enter being connected of (going out) waterpipe and well seat to adopt rubber seal to flexibly connect, the interior angle that can adapt among a small circle changes, and convenient and quick construction, effectively prevents seepage, environmental protection and energy saving at good seal performance.

In the use procedure of plastic inspection well, find that a lot of areas have a large amount of underground water, if manhole is buried, buoyancy force of underground water can upwards push up plastic inspection well seat so, mounted pipeline and well seat generation buckling deformation before will causing, increased the probability leaking.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of manhole well seat for community that weakens buoyancy force of underground water impact.

The utility model solves the manhole well seat for community that its technical problem adopts, and comprises well chamber bellmouth and well body, and described well chamber bellmouth is arranged on the upper end of well body, on described well body, is provided with drain hole, and described drain hole is apart from well body bottom 6～40mm.

Further, the quantity of described drain hole is 4～12.

Further, described drain hole is shaped as circle, ellipse or polygon.Polygon can be rectangle, square, rhombus or trapezoidal.

Further, be provided with vertical reinforcing rib on the outer wall of described well body, described vertical reinforcing rib is parallel with the axis of well body.

Further, the cross section of described vertical reinforcing rib is circular arc.

The beneficial effects of the utility model are: because the bottom at well body is provided with drain hole, therefore when groundwater table rises, water just can enter well body bottom cavity by drain hole, thereby the buoyancy that well body is subject to reduces, and this has just been avoided mounted pipeline and well seat generation buckling deformation.Outer wall at well body can also arrange vertical reinforcing rib, prevents from, when well body is subject to axial load, " protruding " distortion occurs, and prevents that security performance is greatly improved because distortion causes drainage.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Component, position and numbering in figure: well body 1, well chamber bellmouth 2, drain hole 3, vertical reinforcing rib 4.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, the utility model comprises well chamber bellmouth 2 and well body 1, and described well chamber bellmouth 2 is arranged on the upper end of well body 1, on described well body 1, is provided with drain hole 3, and described drain hole 3 is apart from well body 1 bottom 6～40mm.When groundwater table rises, water can enter into the cavity in well body 1 by drain hole 3, discharges air wherein, so just makes the suffered buoyancy of well body 1 reduce, and has avoided mounted pipeline and well seat generation buckling deformation.The quantity of drain hole 3 is traditionally arranged to be 4～12.The shape of drain hole 3 can be circle, ellipse or polygon.

In order to increase the load-carrying ability of well body 1, as shown in Figure 1, on the outer wall of described well body 1, be provided with vertical reinforcing rib 4, described vertical reinforcing rib 4 is parallel with the axis of well body 1.The Main Function of vertical reinforcing rib 4 is to prevent that when well body 1 is subject to axial load, " protruding " occurring is out of shape, prevent from causing drainage because of distortion, simultaneously, the cross section of described vertical reinforcing rib 4 is circular arc, at reinforcing rib 4 projections, carry out rounding, chamfering has strengthened bulk strength, and security performance is greatly improved.
