Requirement to the buried draining culvert pipe in slag storehouse and mine tailing storehouse is to bear very big external pressure, can bear the corrosive action of waste water again, also wants economic and reliable.So be that many engineers and technicians endeavour the problem studied always.
The buried culvert pipe that now use in slag storehouse and mine tailing storehouse has:
1) steel concrete waste pipe: this class culvert pipe can bear bigger external pressure, good economy performance.But anticorrosion problem is difficult to solve.Because the ductility of concrete is relatively poor, easy to crack, so there is the safe mass potential problem always.
2) Glass Steel Tube: can solve anticorrosion problem well, and certain ductility is arranged.But rigidity is relatively poor, is difficult to bear bigger external pressure, easily loses efficacy when buried depth is dark.And involve great expense, can not satisfy the actual requirement of modern project well.
For the draining culvert pipe of pressing in the darker nothing of buried depth, there is the ductility problem of rigidity, intensity and tubing.When the waste water that is corrosive existed, also there was anticorrosion problem in the draining culvert pipe.
Summary of the invention
At these problems, the present invention proposes new structure culvert pipe-reinforcing bar composite pipe, it has the good characteristics of rigidity, intensity and ductility, and can solve anticorrosion problem.
Technological scheme of the present invention is that the reinforcing bar composite pipe is characterized in that tube wall is that " sandwich " formula is composite structured, be that the inside and outside layer of reinforcing bar composite pipe is a steel lining, fill concrete between the steel lining, between inside and outside steel lining positioning bar is arranged, be furnished with spike structure dowel at steel lining and concrete contact layer.
Tube wall is that " sandwich " formula is composite structured, and this structure had both been brought into play the intensity and the ductility of steel, has brought into play the rigidity of concrete again, and economic and practical; Owing to do not press in having in the pipe, guarantee the stable of steel lining, arrange spike structure dowels such as certain " L ", " T ", " P ", to guarantee and the concrete acting in conjunction at steel lining and concrete contact layer, thereby the disengaging of avoiding steel lining and concrete causes the rigidity of steel lining to destroy, and guarantees the proper functioning of reinforcing bar composite pipe.
Aforesaid reinforcing bar composite pipe is characterized in that the anti-corrosion material at the bottom of certain thickness epoxy group is coated on inside and outside steel lining surface.Because steel lining is a main bearing member, and the relative steel of the anticorrosive coat at the bottom of the epoxy group are comparatively soft, therefore can guarantee anticorrosive coat and steel lining co-operation, are unlikely to throw off, and guarantee the proper functioning of reinforcing bar composite pipe.
Aforesaid reinforcing bar composite pipe is characterized in that being respectively cloudy head and positive head in the termination of reinforcing bar composite pipe, at the sun head waling, hoop stiffening rib and " O " type closure gasket groove is set, and is provided with fill orifice and fastening screw at the pipe two ends.
Because the reinforcing bar composite pipe is at the mechanical characteristic of pressure water pipe in the darker nothing of buried depth and Anticorrosive Character design, so under buried depth reaches operating conditions more than the 60m, can normally work.Most importantly can satisfy the needs of modern actual engineering, secondly be to be better than Glass Steel Tube on the cost, and price is exactly a simple installation than the cheap 20-30% of Glass Steel Tube in addition.Therefore, wide application prospect is arranged.
