Abstract

The utility model discloses a double-walled corrugated integral septic tank which consists of a cylinder and two end enclosures arranged at the two ends of the cylinder. A plurality of tightening rings are arranged in parallel on the outer wall of the cylinder along the circumference direction. The cross-section of each tightening ring assumes the shape of a semi-circle, a rectangular or a trapezoid, etc. A hollow or entity structure can be adopted between the tightening rings and the cylinder wall according the situation. The inner wall of the cylinder adopts a smooth structure which is convenient for the flow of dirt and for scooping and washing, and the processing technic can become simpler. After the structure is adopted, the tensile and the compressive strengths and the shock resistance toughness of the product are improved greatly and the service life is prolonged significantly.

Description

Double-wall corrugated type integration manure pit

Technical field:

The utility model relates to a kind of septic tank, relates in particular to a kind of double-wall corrugated type integration manure pit that is used for handling sanitary sewage, belongs to the sewage treatment facility technical field.

Background technology:

Traditional brick and Steel Concrete septic tank easy to leak, contaminate environment, cost height, long construction period, job schedule are slow.The inwall that occurs on the market adopt the double-walled septic tank of ripple type exist circulation poor, easily be detained dirt, defective such as be difficult to draw clearly, and this kind structure tension, resistance to compression, resistance to impact shock are limited, and have the drawback of complex manufacturing.

The utility model content:

For overcoming the defective of prior art, the utility model aims to provide a kind of double-wall corrugated type integration manure pit, adopts this kind septic tank, and circulation is good, and inner being difficult for is detained dirt, and tension, resistance to compression, resistance to impact shock are all high.

The technical solution of the utility model is achieved in that

Double-wall corrugated type integration manure pit is made of cylindrical tube and the end socket of being located at the cylindrical shell two ends, along the circumferential direction is provided with some tight loops on the outer wall of described cylindrical shell side by side.

The cross section of described tight loop or be semicircle, or be rectangle, or be trapezoidal.

The face of described end socket is provided with radially stiffening web.

Beneficial effect: after adopting this kind structure, the inwall of integration manure pit is level and smooth, and circulation is good, easily draws clearly, and outer wall convex-concave shape in wave shape, tension, resistance to compression, resistance to impact shock improve greatly, thereby have increased the work-ing life of septic tank, and complete processing is simple.

Description of drawings:

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

Fig. 2 is that the A-A of Fig. 1 is to sectional view.

Number in the figure: 1, cylindrical shell, 2, end socket, 3, tight loop, 4, stiffening web radially, 5, dividing plate.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Embodiment:

Embodiment: referring to Fig. 1, Fig. 2, the double-wall corrugated type integration manure pit of present embodiment, constitute by cylindrical tube 1 and the end socket 2 of being located at the cylindrical shell two ends, drum outer wall along the circumferential direction is provided with some tight loops 3 side by side, described tight loop is the stiffening web of corrugated or convex concave, its cross section can be that semicircle also can be a rectangle or trapezoidal, tight loop is connected with the drum outer wall contact position closely and is an integral body, it can be integrally formed with cylindrical shell, also can be attached on the cylindrical shell, can be hollow structure between tight loop and the drum outer wall, also can be entity structure, the inwall of tube is level and smooth, is easy to circulation, can not be detained dirt, the face of two ends end socket is provided with radially stiffening web 4.Because cylinder body outer wall adopts annular corrugated or machicolated form ripple struction, makes tension, resistance to compression, the resistance to impact shock of integration manure pit improve greatly, simultaneously, the radially stiffening web of two ends end socket projection has also improved the compressive strength of septic tank greatly.In addition, also radially be provided with the dividing plate 5 that is the filter screen shape in the cylindrical shell, it not only plays precipitation, filtering effect, the effect that also has pressure-bearing.

Claims

1, double-wall corrugated type integration manure pit is made of cylindrical tube (1) and the end socket (2) of being located at the cylindrical shell two ends, it is characterized in that, along the circumferential direction is provided with some tight loops (3) on the outer wall of described cylindrical shell side by side.

2, double-wall corrugated type integration manure pit according to claim 1 is characterized in that, the cross section of described tight loop (3) or be semicircle, or be rectangle, or be trapezoidal.
