Abstract
The present invention relates to a steel skeleton composite arch which is particularly suitable for a drain arch which is buried in the depth of more than 60 meters and has no inner pressure. The present invention is divided into an upper arch and a lower arch, wherein the arch wall of the upper arch and the arch wall of the lower arch are respectively a 'sandwich'-typed composite structure, the inner layer and the outer layer of the steel skeleton composite arch are steel linings, the inner steel lining and the outer steel lining are connected into a shape of a sandwich layer by a connecting plate, concrete is filled between steel linings, the inner steel lining and the outer steel lining are connected by a positioning steel rib, and nail-shaped structural anchor ribs are arranged on the steel lining and a concrete contact layer of the upper arch. The present invention has the characteristics of high rigidity, high strength and good ductility, and can well solve an anticorrosion problem.
Description
Technical field
The reinforcing bar composite arch is the interior draining arch of pressing of a kind of brand-new nothing.The invention belongs to does not have interior the pressure, bears the buried draining arch of higher external pressure, especially for the draining arch of pressing in the nothing of buried depth more than 60m.
Technical background
The draining arch of pressing in lower embedding type does not have uses in engineering in a large number.Along with the raising of science and technology development and production technology,, require not have interior draining arch of pressing and bury darker and darker in the place of many sand-like solid accumulations.Acting on of draining arch plays crucial effects in the engineering.For example, as mine tailing storehouse, waste residue storehouse or the slag field of one of important production facility of many industrial and mining enterprises, its drainage system mostly is tunnel and draining pipe culvert.Therefore, the draining culvert pipe is a kind of form that extensively adopts water discharge tunnel is subjected to the restriction of landform and geological conditions.The drainage system in mine tailing storehouse and slag storehouse makes one of important leverage of its safe operation.Along with the raising of production technology, the piling height in mine tailing storehouse and waste residue storehouse is more and more higher, has surpassed 60m as the ardealite slag field of yellow wheat mountain range phosphorous chemical industry group company, the high 100m that surpasses of design heap; The high 125m of heap is intended in the red phosphorus slag field of Kaiyuan City, Yunnan; High 74m is piled in the urn good fortune ardealite slag field in Guizhou; Therefore, more and more higher to the requirement of not having interior draining arch of pressing.
Requirement to the buried draining culvert pipe in slag storehouse and mine tailing storehouse is to bear very big external pressure, can bear the corrosiveness 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 bar concrete gutter: 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 reinforced plastic pipe: can solve anticorrosion problem well, and certain ductility is arranged.But rigidity is relatively poor, is difficult to bear
Big external pressure easily lost 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 the reinforcing bar composite arch of new structure, it has the good characteristics of rigidity, intensity and ductility, and can solve anticorrosion problem.
Technical scheme of the present invention is, the reinforcing bar composite arch, it is characterized in that its divides serve as reasons arch and arch down, arch and following arch buttress are that " sandwich " formula is composite structured, be that the inside and outside layer of reinforcing bar composite arch is a steel lining, connecting inside and outside steel lining with junction plate is sandwich-like, fills concrete between the steel lining, connect spacer bars between inside and outside steel lining, be furnished with spike structure dowel at the steel lining and the concrete contact layer that arch up.
Buttress 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 arch, guarantee the stable of steel lining, steel lining and concrete contact layer in arch are arranged spike structure dowels such as certain " L ", " T ", " P ", to guarantee and the concrete acting in conjunction, thereby the disengaging of avoiding steel lining and concrete causes the rigidity of steel lining to destroy, and guarantees the operate as normal of reinforcing bar composite arch.
Aforesaid reinforcing bar composite arch is characterized in that the anti-corrosion material at the bottom of certain thickness epoxy radicals 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 radicals are comparatively soft, therefore can guarantee anticorrosive coat and steel lining co-operation, are unlikely to throw off, and guarantee the operate as normal of reinforcing bar composite arch.
Because the reinforcing bar clad 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 condition of work more than the 60m, can normally work.Most importantly can satisfy the needs of modern actual engineering, secondly be to be better than glass reinforced plastic pipe on the cost, and price is exactly a simple installation than the cheap 20-30% of glass reinforced plastic pipe in addition.Therefore, wide application prospect is arranged.
