Description
Technical field
The invention patent belongs to plumbing plastic pipe field more particularly to the universal drop height of drainage connecting pipe angle can
Any setting formula plastic inspection well.
Background technique
With carrying forward vigorously for Urbanization Construction, the technological innovation in plumbing field is also maked rapid progress therewith.Existing inspection
It looks into well to include but not only limited: crossing well, catch-basin, charge for remittance well, drop well, the well that crosses, rotation angle well, filter well, water-distributing well, rainbow
Inhale well etc., find that the common shortcoming of product examination well disclosed above has after use: inspection shaft uses injection molding, rotational moulding, pressure injection work
Skill is made through mould shape, is limited by shaper, and the well room model specification of inspection shaft, the buried depth height of inspection shaft, row are caused
Water connecting tube interface angle, drainage connecting pipe drop height difference are single.Specific shortcoming has: one of deficiency, it is necessary to use other
Structural walls pipeline reaches inspection shaft buried depth requirement for height as pit shaft Elevated section, destroys the integrality of shaft structure, well
Cylinder increases junction can not secondary aperture, it is difficult to adapt to part drop height difference requirement；The two of deficiency, drainage connecting pipe interface angle
Single, pit shaft adapts to the drainage connecting pipe interface difference angle of drainage connecting pipe net there are many secondary apertures at the construction field (site)
Degree requires, and also increases pipe leakage point while increasing construction cost；The three of deficiency are passed through using techniques such as injection molding, rotational moulding, pressure injections
The pit shaft of inspection shaft made of mould shape is single layer structure, and compression strength is low, usually at the construction field (site) because backfill deformation or
Rupture, or cracked because being impacted, or because of rehandling breakage, lead to occur leak in use, service life contracting
Short equal qualitative problems of construction.
