Abstract
The utility model belongs to building units in the municipal engineering. The scheme of a reinforced concrete water drainage pipe with a PVC anti-corrosion lining is particularly provided to solve thedifficult problem of shortened service life of the reinforced concrete pipe due to invasion of corroded substances; and the reinforced concrete water drainage pipe comprises the reinforced concrete pipe and an anti-corrosion PVC lining. A plurality of spiral line-shaped T-type buttons parallel to each other are arranged on the outer surface of the cylinder of the PVC lining; the T-type buttons are firmly combined with cement pipes into a whole during pouring cement; and seams of the PVC lining are required to be narrowly spliced, and the seams of the lining between pipes are also required tobe narrowly spliced, so as to ensure that the corrosive substances are separated from the concrete pipe walls. The reinforced concrete water drainage pipe by adopting the scheme has the characteristics of simple structure, low manufacturing cost, corrosion resistance and small internal resistance force of water flow, and can prolong the service life of the reinforced concrete pipe for 20 years.
Description
Technical field:
The utility model belongs to the structural element class of municipal engineering.It is specifically related to a kind of structure of the concrete reinforced pipe with the PVC corrosion protective lining.
Background technique:
At present in the city of China, all be with the pipeline of concrete reinforced pipe as draining and drainage project, it have cost low and working life still can product, but along with developing rapidly of industry, acidity that contains in the sewage (particularly industrial wastewater) and toxic substance are more and more, waste pipe is produced certain erosion, for example, in effluent discharge, just contained H at present
2Corrosive gas or liquid such as S, corrosive gas or liquid penetrate into inside concrete by concrete pore, cause the volume of concrete swelling cracking, can make its corrosion expand and concrete risen when harmful matter runs into reinforcing bar and split, reduced the working life of tubing significantly until peeling off.Therefore, various have erosion-resisting waste pipe and arise at the historic moment, as: glass reinforced plastic sand pipe, double-wall corrugated pipe, pvc pipe or the like, but all exist tangible narrow limitation in actual applications.It is low to add sandpipe external pressure weight bearing power such as glass fibre reinforced plastics, costs an arm and a leg; And that double-wall corrugated pipe and pvc pipe bear the ability of interior pressure, external pressure is all very low, and price is not cheap yet.
Summary of the invention:
The purpose of this utility model is for overcoming the special this programme that proposes of defective---the reinforced concrete sewer pipe of band PVC corrosion protective lining that aforesaid several energy corrosion protection pipeline exists, it has adopted new structure to solve having to have the working life that can guarantee reinforced concrete pipiline under the situation of corrosive material significantly to improve, and economic effect is outstanding.
By as above design, the reinforced concrete sewer pipe of the band PVC corrosion protective lining that this programme proposed is characterized in that at the internal surface of concrete reinforced pipe in conjunction with one deck corrosion-resistant PVC material.
In this programme, its corrosion-resistant PVC material becomes tubular, has the T type key of a plurality of zigzag shapes that are parallel to each other on its outer surface, and the PVC tube combines with concrete reinforced pipe by a plurality of T type keys.
Adopt this programme can embody following and superiority: 1. because of industrial expansion, often have corrosive materials such as H2S in the waste water of discharging, tube wall to concrete reinforced pipe has the obvious corrosion effect, can reduce the life-span 20～30%, liner with PVC makes the tube wall of harmful matter and reinforced concrete isolated, improve the anti-corrosion property energy, improved economic effect; 2. the PVC liner of Shi Yonging can also avoid it to leak in the soil with poisonous and hazardous gas or liquid seal in pipeline, has avoided the pollution to the soil, has improved the effect of environmental protection; 3. the tubular liner of PVC is that the PVC plate that will have a plurality of T type keys in advance is cut into strip, regulate the bonding one-tenth tubular in angle of inclination of billot by size requirement, the PVC jacket casing on the aperture surface of pipe die, is added the prefabricated netware of reinforcing bar, and concrete perfusion promptly forms the product of this programme; 4. the T type key on the PVC tube combines with body when concrete perfusion, and lining and body are very firm in combination; 5. beyond the problem of this programme, also designed a special instrument of checking the leakproofness of lining, the seam of lining all will be carried out narrow examination when the seam of PVC material in every pipe joint and tube and tube were connected, guaranteeing the tight of lining, and then the life-span that guarantees to improve concrete reinforced pipe; 6. this programme have simple in structure, processing ease, water flow inside resistance little, can improve concrete pipe working life, characteristics that economic benefit is outstanding significantly.
Description of drawings:
Fig. 1 is the structural representation that this programme has the reinforced concrete sewer pipe of PVC corrosion protective lining.This figure is the sectional drawing perpendicular to the pipe position of center line.
Fig. 2 is the schematic representation of the PVC lining seam in the pipe.
Embodiment:
This programme is to propose for the destruction problem that solves corrosive goods confrontation concrete reinforced pipe body in the drainage pipe.It is made up of the liner 2 of reinforced concrete tube wall 1 and etch-proof PVC material, at the outer surface of corrosion-proof lining a plurality of T type keys 3 is arranged.Its anticorrosive PVC liner is tubular, at the outer surface of PVC tube the T type key of a plurality of zigzag shapes that are parallel to each other is arranged, and T type key and concrete tube body are combined closely.To be the PVC plate that will have a plurality of parallel T type keys be cut into rectangular along the direction of T type key for it, and be rolled into tubular obliquely, the side is bonding, the angle of regulating its inclination can form the diameter dimension of requirement, with the PVC material sleeve of tubular on the internal mold of concrete pipe, put into bar frame in die cavity, concrete perfusion promptly forms this product.Because the existence of T type key makes the very firm of both combinations.After pipe was pegged graft in engineering, the corrosion-proof lining between the pipe was also bonding mutually, and bonding seam must guarantee tightly, could guarantee that concrete pipe is not subjected to the invasion and attack of corrosive deposit.We have also designed the special instrument of checking the seam leakproofness in outlying for this reason, and it can check out small hole and crack.That this programme product has is simple in structure, low cost of manufacture, anti-corrosion capacity height, water flow inside resistance are little, improve the characteristics in concrete pipe life-span, the favorable comment that is subjected to not seeing earlier the person significantly.
Claims (2)
