This invention relates to a drainage element having an open top body made of concrete that surrounds the drainage channel. Usually such items for drainage design in the form of a gutter or drain elements. Through its open top form they form area of the inlet used for inflow of surface water, for example, for street drainage of sewage and surface drainage. The housing of such elements for drainage is usually made of concrete or polymer concrete. They can also contain a support, for example support surface to overlap, and the overlap can be made of concrete or metal. To increase the strength of such elements for drainage often they contain steel reinforcement. Meanwhile, the steel reinforcement has the following disadvantages. First, the steel can be correlated, in particular, if the surrounding concrete loses its alkaline nature. Secondly, the steel is relatively heavy and increases the overall weight of the item for drainage.

Therefore, the objective of the invention is to create such an element for drainage, which has a high mechanical strength and is less susceptible to corrosion.

This task is solved by the element for drainage with signs of paragraph 1 of the claims. Preferred universes the tation of the invention are subject of the dependent claims.

In accordance with the invention, the housing element for drainage contains basalt fiber.

Compared with steel rebar, basalt fibres have the advantage that they do not corrode, even if the concrete has lost its alkaline nature. In addition, by their nature, basalt fibers are mineral substance, so they are connected with the concrete more intensively than steel with concrete. Basalt fibers have very high tensile strength, so they are very well suited to improve the mechanical properties of concrete. Fiber does not corrode, is elastic and has a relatively small weight, so with the help of basalt reinforcement can be made of lighter elements for drainage than in the case of conventional elements for drainage with steel rebar.

Most elements for drainage form the elements of a drain that collects in the gutters to drain water away from roads or surfaces. Such drain elements are U-shaped housing which is open at the top, and two vertical side parts of the U-shaped housing, generally relies floors of concrete or steel, having inlets for surface water. When assembled the item drain overlap, in fact, installed flush with surrounding what again, for example, the area for Parking cars or expensive, so the water through holes may flow in the channel element drain. Here the water is withdrawn on site sewage systems.

Preferably basalt reinforcing fibers are placed in the housing in parallel and/or perpendicular to the axis of the outlet, to thereby increase the strength of the U-shaped body in all directions.

Mainly used fiber with the following mineral content:

35-65% SiO2,

10-30% Al2O3

by 2-15% FeO, CrO and Mao

by 0-10% K2O and PA2O.

In the manufacture of basalt fibers is melted and the molten basalt pull fiber diameter preferably 20-1000 μm, in particular 50-500 μm. Fiber can be easily implemented in the case in the manufacturing process, for example, by the method of vibratory tamping or casting.

Easier handling is obtained if the fibers bind into bundles and using linking polymers are combined in the bars. These rods can be bent, as conventional steel reinforcement, and connect to the grid, which are then fixed in the housing. Because basalt rebar does not corrode, the grid can take it to the edge of the moulds, where they can be attached to the form. However, you can apply and spacers, preferably also made of basalt, which remain in the body. The advantages to the company of such decision is thanks to the use of non-corroding cast reinforcing material on the basis of basalt this material is quite safe up to communicating with the atmosphere of the edge zones of the housing element of the drainage system, which in the case of steel reinforcement is not permitted.

The vertical part of the housing element for drainage, preferably on its upper side, may have a bearing surface for the floor.

If concrete is made the floor, basalt fibers preferably reinforced and overlap. In this case, the reinforcing fibers are predominantly parallel to the plane of the ceiling.

The above-mentioned elements of a drain you can connect the ends in a long, drains, and in itself, the connection ends, seal the ends and fastening drains in the soil is known, so detailed, it did not explain.

Next, on the basis of a schematic drawing describes an example embodiment of the invention. The drawing shows the following :

Figure 1 - cut item drain across the axis of the drain.

The cross section of the element 10 drain has a U-shaped body 12 for channel drain, containing the lower part 14, which extend up to the two vertical portion 16. Thus, the U-shaped body 12 surrounds made in the form of a gutter channel 18 of the drain, which is surrounded by the bottom part 14 and two the slight pressure from the beginning parts 16. On its upper side two vertical pieces 16 have the support surface 20 for supporting the slabs 22 of concrete or metal. In the overlap 22 has inlet openings, so that surface water can through the ceiling 22 to flow into the channel 18 of the drain and there to be allotted. The housing 12 consists of concrete, in which the valve provides communication of basalt fibers. Thus, provided 24 hours basalt perpendicular to the axis of the outlet and extending in the vertical portions 16 and bottom 14. Passing across the axis of the outlet connection 24 of basalt fibers are connected with links 26 of basalt fibers running parallel to the longitudinal axis of the gutter. Thus, thanks to the contacts 24 and 26 of basalt fibers perpendicular to and along the longitudinal axis of the gutter, formed wire mesh, as in the case of conventional steel reinforcement. Wire mesh preferably using spacers 28 basalt rely on the formwork, after pouring or vibration of the concrete mix spacers 28 remain in the housing. Due to the fact that the spacers 28 of the basalt does not corrode, the passage of the struts to the outer part of the concrete shell is not a problem.

If the overlap 22 is made of concrete, it may also contain reinforcing connection of basalt fibers Popper is to and along the longitudinal axis of the drain in the grid to increase the bearing capacity of the slab 22. The use of spacers is not necessarily because of the basalt fibers may pass to the outer part and propped up there, as these relations of basalt fibers corrosion is not affected.
