Description
Technical field
The utility model relates to tubing technical field, particularly a kind of double-wall corrugated pipe.
Background technique
Double-wall corrugated pipe is that a kind of inner wall smooth is smooth, and outer wall is trapezoidal or arc corrugated rib, is the tubing of hollow between inner and outer wall ripple.Have that light weight, corrosion-resistant, ageing-resistant, product strength are large, the feature such as good bending property and construction install convenience, be widely used in industry and civil outdoor drainage system, belong to environment-friendly product.It has become the first-selected tubing of pipeline field " to mould Dai Gang ", which overcomes that the installation difficulty such as cement pipe, stoneware pipe, cast iron tube are large, easy-to-rust, resistance to water-flow are large, shortcoming that breed bacteria, life-span are short.
But in use, due to the uneven sink-float of soil, can impact double-wall corrugated pipe, once exceed the anti-pressure ability of double-wall corrugated pipe, destruction to a certain degree can be caused to double-wall corrugated pipe, affect the working life of double-wall corrugated pipe.In addition, also there is installation, connect inconvenient and not corrosion resistant problem in existing double-wall corrugated pipe.
Therefore be necessary that designing a kind of double-wall corrugated pipe solves these problems.
Summary of the invention
It is strong that the utility model object is to provide a kind of anti-pressure ability, can the uneven sink-float of adapted soil, and easy for installation, the double-wall corrugated pipe of long service life.
The technical solution of the utility model is achieved in that
A kind of double-wall corrugated pipe, comprise internal layer straight tube and outer bellows, the recessed edge of outer bellows and the outer wall of internal layer straight tube are fixed and are fitted, the outer flange of bellows and the outer wall of internal layer straight tube form the ripple space at interval, ripple is provided with cross bracket in space, cross bracket fixedly forms by transverse slat is vertical with riser, cross bracket is fixed on the outer wall of internal layer straight tube and the inwall of outer bellows, plural U-shaped draw-in groove is provided with outside the head end of internal layer straight tube, the opening of U-shaped draw-in groove be provided with inside inclination card point, annular groove is provided with inside the head end of internal layer straight tube, the outer bellows of internal layer straight tube tail end is provided with the triangle buckle coordinated with U-shaped draw-in groove, the bulge loop coordinated with annular groove is provided with inside the tail end of internal layer straight tube, the inwall of internal layer straight tube is provided with anticorrosive coat.
Further, the inwall of described internal layer straight tube is smooth surface.
Further, also seal arrangement is provided with in described annular groove.
Further, described seal arrangement is seal ring.
Further, described anticorrosive coat is epoxy coating layer, epoxy novolac coating layer or anti-corrosion polyurethane coating layer.
The beneficial effects of the utility model are: in ripple space, be provided with cross bracket, enhance the anti-pressure ability of double-wall corrugated pipe, make double-wall corrugated pipe can the better uneven sink-float of adapted soil and external impact, and be not easy to be destroyed, improve the working life of double-wall corrugated pipe; The engaging of U-shaped draw-in groove and triangle buckle, makes to install between double-wall corrugated pipe easy to connect, as long as by head end facing to tail end, make triangle buckle snap in U-shaped draw-in groove, save time few power, and the coordinating of annular groove and bulge loop, can sealing be played, prevent the effect of leaking; Arranging of anticorrosive coat can make internal layer straight tube not be corroded in the face of various sewage, improves working life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
