Upper and lower combined plastic septic tank assembly
technical field:
The present invention relates to environmental technology field, particularly one upper and lower combined plastic septic tank assembly.
background technology:
Septic tank is process ight soil and the equipment of in addition filtering-depositing, and allow sewage solids material decompose at the bottom of pond, the aquation material on upper strata enters pipeline and flows away, and septic tank has the place of the time decomposition of abundance as rubbish such as human feces to solid matter.Septic tank is generally the principle utilizing precipitation and ozone fermentation, removes the organic treatment facility of suspension in sanitary sewage, belongs to elementary filtration life process structures.
Existing universal traditional manure pit can be divided into following several: cast-in-situ steel reinforced concrete septic tank, brick septic tank.Above several prods all has certain limitation: cast-in-situ steel reinforced concrete septic tank and the impact of brick septic tank climate, winter construction inconvenience, enters microthermal climate constructional difficulties.In addition, serious leakage is started after the septic tank that more seriously tradition uses uses several years, severe contamination underground drinking water source and Urban Underground water supply line.
Although there is the integrated cesspool that plastics are made in prior art, traditional manure pit Problems existing is solved with this, but the septic tank that existing plastics are made exists following problem: the impact being subject to plastic material itself, the compressive property of the septic tank that plastics are made is poor; Integrated plastic septic tank takes up room greatly in transportation; Other Assembled septic tank splicing structure is complicated, needs at multiple joints, and sealing problem is difficult to solve; Left and right combined septic tank is higher due to it, although solve sealing problem, is difficult to install.
summary of the invention:
In view of this, be necessary to provide a kind of crushing resistance by force and the septic tank of the combined plastic up and down assembly of easily sealing.
A kind of combined plastic septic tank assembly up and down.Upper and lower combined plastic septic tank assembly is the semi-closed structure of open at one end, its sidewall extends outward connecting wall at open end, the profile of connecting wall is by two sections of tangent connections of straight line, two semicircles, blind end is a boss, the profile of blind end is equidistantly reduced by the profile of connecting wall to obtain, connected by one week sidewall between open end and blind end, sidewall is the curved surface that there is curvature at least in the two directions, and the cross section of sidewall, the intersection of sidewall and connecting wall, the intersection of sidewall and blind end is wavy, at the pedestal that sidewall two ends are connected as pipeline respectively to outer formation boss with blind end junction, at the pedestal that sidewall two middle side part connects as pipeline respectively to outer protrusion formation one boss, its height of the pedestal at sidewall two ends is between the pedestal and blind end of sidewall both sides.
The sidewall of blind end both sides is sentenced curved form at blind end and is crossed, and the boss forming blind end is divided into discontinuous part by curved surface.
Pedestal sidewall has one week seal groove, is with a circle bolt positioning groove outside seal groove.
Upper and lower combined plastic septic tank assembly of the present invention is convenient to be transported and is easy to install, and needs the interface of docking simple, adopts a large amount of curved surface intensity high, rational in infrastructure simultaneously.
accompanying drawing illustrates:
Accompanying drawing 1 is the schematic top plan view of upper and lower combined plastic septic tank assembly.
Accompanying drawing 2 is schematic front view of upper and lower combined plastic septic tank assembly.
Accompanying drawing 3 is that schematic diagram is looked on a left side for upper and lower combined plastic septic tank assembly.
In figure: intersection 12, pedestal 4, pedestal 5, curved surface 13, the bolt positioning groove 41 of the intersection 11 of sidewall 1, open end 2, connecting wall 21, blind end 3, connecting wall profile 211, sidewall and connecting wall, sidewall and blind end.
embodiment:
As Fig. 1 ~ Fig. 3, a kind of combined plastic septic tank assembly up and down.Upper and lower combined plastic septic tank assembly is the semi-closed structure of open at one end, its sidewall 1 extends outward connecting wall 21 at open end 2, the profile of connecting wall 21 is by two sections of tangent connections of straight line, two semicircles, blind end 3 is a boss, the profile of blind end 3 obtains for equidistantly being reduced by connecting wall profile 211, connected by one week sidewall 1 between open end 2 and blind end 3, sidewall 1 is the curved surface that there is curvature at least in the two directions, and the cross section of sidewall 1, the intersection 11 of sidewall and connecting wall, the intersection 12 of sidewall and blind end is wavy, at the pedestal 4 that sidewall 1 two ends are connected as pipeline respectively to outer formation boss with blind end 3 junction, at the pedestal 5 that sidewall 1 liang of middle side part connects as pipeline respectively to outer protrusion formation one boss, its height of the pedestal 4 at sidewall 1 two ends is between the pedestal 5 and blind end 3 of sidewall 1 both sides.
In the present embodiment, the sidewall 1 of blind end 3 both sides is sentenced curved surface 13 form at blind end 3 and is crossed, and the boss forming blind end 3 is divided into discontinuous part by curved surface 13, with reference to figure 1, Fig. 2.Pedestal 4,5 sidewall has one week seal groove, is with a circle bolt positioning groove 41 outside seal groove.
