Description
Technical field
The invention belongs to the concrete pipe field, especially a kind of fiber concrete pipe.
Background technique
Be applied to the concrete pipe in plumbing field, mainly comprise flat mouth, tongue and groove, joint socket and steel bell and spigot by its interface shape classification.The concrete pipe of the heavy caliber concrete drain tile of the above-mentioned classification of foundation, pipe wall material adopts concrete, and its tube wall is thicker, causes the tubing own wt bigger, and lifting, transportation and installation are very difficult, and expense is higher; In tube wall, also can be embedded with the Framework Of Steel Reinforcement of forming by circumferential reinforcement and longitudinal steel bar, the main effect of Framework Of Steel Reinforcement is the stability that can increase concrete pipe integral body to a certain extent, improves the ability that concrete tube wall is resisted external pressure load and internal water pressure.Though Framework Of Steel Reinforcement can improve the mechanical property of tubing, along with the rise day by day of iron and steel price, cause the tubing cost constantly to raise, thereby greatly reduce the profit margin of enterprise.Country has put into effect the policy of multinomial energy-saving and emission-reduction for this reason, and enterprise seeks new technology and replaces steel imperative.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of fiber concrete pipe is provided, it is low that this tubing has the cost of raw material, in light weight, tension, bending resistance, shearing resistance and twisting strength are higher, and durability and fatigue resistance are better, and shock resistance, anti-impact are ground, anti-cavitation erosion ability is stronger.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of fiber concrete pipe, component and the ratio of weight and number thereof of wherein pouring into a mould the fiber concrete of this tubing are:
322～540 parts of cement;
140～220 parts in water;
475～828 parts of sands;
864～1306 parts in stone;
0.2～20 part of fiber.
And described fiber is polypropylene fiber or modified polypropylene fiber.
And the length of described fiber is 3～60mm, and fiber diameter or equivalent diameter are 18～1.2 * 10
6μ m.
And, coaxial respectively tongue and groove, Ping Kou, joint socket or the steel bell and spigot of being shaped in described tubing two ends.
Advantage of the present invention and beneficial effect are:
1. the fiber in this fiber concrete pipe is polypropylene fiber or modified polypropylene fiber, can effectively improve tension, bending resistance and the shearing strength of tubing, its tensile strength improves 25%～50%, and resistance to flexure improves 40%～80%, and shearing strength improves 50%～100%.
2. add polypropylene fiber or modified polypropylene fiber in the tube wall of this fiber concrete pipe, replaced the Framework Of Steel Reinforcement structure, under situation, reduced the cost of tubing, improved economic benefit of enterprises with same opposing external pressure loading intensity.
This fiber concrete pipe with respect to common concrete pipe under the constant situation of quantity of reinforcement, the wall thickness of tubing can be reduced to 1/4～3/4 of original wall thickness, alleviate the weight of tubing significantly, thereby make each process of transportation, lifting, installation become easy, and the energy consumption in these processes, manpower consumption, bypass laying etc. all can significantly be reduced, not only save the engineering overall cost, also realized the effect of energy-saving and emission-reduction.
4. the cost of raw material of the present invention is low, in light weight, tension, bending resistance, shearing resistance and twisting strength height, durability and fatigue resistance are better, and shock resistance, anti-impact are ground, anti-cavitation erosion ability is stronger, and resistance to cracking is better, meeting the energy-saving and emission-reduction policy, is the Updated product of existing concrete pipe.
