Definitions

  • the invention relates to a drain device, the drain device having an inlet opening designed to accommodate a cover and an outlet opening connected to the inlet opening.
  • the drain device can be a drain cup for a drain, in particular for a bridge drain or building and industrial building ceiling drain, or spout for sealing drainage.
  • Drainage basins are known from the prior art, which are intended to be used for bridge drainage basins and bridge sealing drainage, among other things.
  • Bridge drains are part of the bridge drainage and ensure the drainage of surface water and the water that has penetrated up to the bridge sealing.
  • the most important construction elements are the bridge drains, the bridge sealing drainage and a pipe system of connecting and collecting pipes.
  • the bridge drain consists of an upper part (top frame with inlet grille) and a lower part - the actual drain cup with a pipe connection piece.
  • the sealing drainage consists of the so-called nozzle with pipe connection piece and a cover, which is intended to prevent asphalt from penetrating into the drain and to enable drainage of the sealing level.
  • the drainage cups can also be used for draining flat roofs, garages, etc. in building and industrial construction.
  • drain pans are made of cast iron, stainless steel (bridge construction) or plastic (building and industrial construction) and used accordingly.
  • the bond between these materials and the enveloping concrete which decreases over time, as well as damage in the contact area with the liquid or bituminous sealant attached to the drain, lead to leaks and bypasses in the immediate vicinity of the drain and thus also to damage to the structure (e.g. bridge or roof). due to corrosion of the adjacent reinforcement and spalling of the concrete.
  • the durability (corrosion resistance) of the cast iron is also not within the desired range as a result of the high stress caused by the water running off, including de-icing agents, and this leads to a shorter service life for the drains (e.g. "spongiosis").
  • the service life of the plastic components is also limited by an embrittlement process due to UV exposure.
  • the use of stainless steel drain pans is very expensive. There is no solution to the problem of declining adhesion or fatigue failure of bituminous waterproofing, corrosion of cast iron material and embrittlement of plastics.
  • the DE 16 09 080 A1 describes a modular system for a water drain (gully). This system is primarily intended to prevent or prevent contamination of the inlet area or the sewer pipe system through the final steps, such as embedding the funnel and creating smooth finishes and similar surfaces made of concrete and asphalt, with the individual parts funnel, inlet grate, sludge bucket and installation aid protective cap enable subsequent cleaning by removing the protective cap or the inlet grate.
  • Plastic, asbestos cement or sheet steel, for example covered with a layer of asbestos cement, are mentioned for the production of the funnel.
  • the EP 2 695 992 A2 shows different forms of slotted channels, ie linear drainage devices. These slot channels can be made from ultra-high-strength concrete, with wall thicknesses of around 6 cm being achievable. Polymer fibers, among other things, can be provided as reinforcement.
  • the compressive strength can be measured, for example, using the test methods specified for normal concrete in the EC 2 standard (Eurocode 2).
  • the present invention reduces the maintenance and consequential damage costs and, on the other hand, increases the robustness of building structures (including bridges and flat roofs) over their lifetime.
  • the service life of a gully made of the cement-based composite material is significantly longer than the gully made of cast iron and is estimated to be approximately four times longer.
  • the life cycle costs for repairs over the useful life of a bridge can be significantly reduced by using the drainage device according to the invention. Extensive damage to the drainage system itself and consequential damage to the adjacent supporting structure are effectively prevented.
  • the drainage device according to the invention can also be manufactured as a finished part in the concrete plant, regardless of the weather, with high accuracy and consistent quality.
  • the drain device has such a low weight that the drain device can be carried by one person from a discharge point to an installation point without too much stress, resulting in a further advantage.
  • the density of the drain device can be 2,000-2,600 kg/m 3 , for example. Irrespective of this, the wall thickness of the drain device is 1.0 - 2.5 cm.
  • the cement-based composite material comprises fibers, preferably plastic fibers or also carbon and steel fibers, which further increases the material properties of the drainage device.
  • the fibers have a high tensile strength, which in particular further improves the tensile load-carrying behavior of the drainage device.
  • the outflow device has a greater roughness on its outside than on its inside.
  • the surface quality of the drainage device according to the invention ensures a correspondingly good bond between the drainage device and the structural concrete on the outside of the drainage device and a permanent and tight connection of the sealing system on the flanges.
  • the inside is smooth in order to be able to drain away the accumulating water as quickly as possible and to be able to prevent dirt, such as dust, sand, abrasion, etc. from adhering over a long period of time.
  • the drainage device in order to achieve greater roughness, can be open-pored or structured on its outside and closed-pored on its inside.
  • the open porosity or structure on the outside ensures a further improved bond between the drainage device and the structural concrete, while the closed porosity prevents water from penetrating.
  • the outside of the drain device In order to achieve the desired roughness of the outside, provision can be made for the outside of the drain device to be blasted using a blasting process (e.g. sand, high-pressure water jets) or is structured by inserting a matrix into the outer formwork, which means that an approximately 10-times higher adhesive strength bond can be achieved with normal concrete than is known with cast iron drainage equipment.
  • a blasting process e.g. sand, high-pressure water jets
  • a matrix into the outer formwork
  • the inlet opening of the drainage cup is designed as a flange, which has a surface facing away from the second opening for bonding to a bitumen sealing strip.
  • the inlet opening of the drain device which is designed as a flange, also provides a good base for a tight connection with other sealing systems.
  • the thermal material properties of the drainage device essentially correspond to the material properties of normal concrete.

  • the drainage cup 1 consists of a cement-based composite material, according to the invention ultra-high-strength concrete, with a compressive strength of at least 110 N/mm 2 .
  • a very thin wall thickness, according to the invention of 1.0-2.5 cm, can be achieved for the drain cup 1.
  • the cement-based composite material (ultra-high-performance concrete) consists of the following components, for example: - 600-800kg cement - 80-120kg microsilica - 200-400kg quartz powder - 900 - 1,300 kg Quartz sand/basalt chippings - 150-200kg Water - 15-20kg flow agent - and fibers optional ⁇ 5-15kg Plastic fibers (polymer fibers) ⁇ 20-40kg carbon fibers ⁇ 80-160kg steel fibers
  • the composite material achieves a density of 2,000 - 2,600 kg/m 3 .
  • the drain cup 1 has an inlet opening 3 and an outlet opening 4 connected to the inlet opening 3, so that the drain cup 1 forms a tapering funnel from the inlet opening 3 to the outlet opening 4. Liquids flowing into the inlet opening 3 can therefore flow through the drain cup 1 and exit through the outlet opening 4 .
  • the inlet opening 3 is preferably larger than the outlet opening 4.
  • the drain cup 1 is rotationally symmetrical about an axis A, so that the inlet opening 3 and the outlet opening 4 are circular.
  • the inlet opening can have an outer diameter (flange outer edge) of 58 cm, an inner diameter (funnel) of 38 cm and the outlet opening an outer diameter (for the socket diameter of the connecting pipe) of 20 cm, with the inner diameter generally being dependent on the wall thickness.
  • the inlet opening 3 and the outlet opening 4 could also be oval or angular, as a result of which the drain cup 1 can also assume a correspondingly different shape.
  • the drain cup 1 is designed in the area of the inlet opening 3 to accommodate a commercially available cover 5, which is intended to prevent asphalt from penetrating into the drain cup 1 or a derivation connected to it.

  • the surface 7 extends in a plane which is normal to said axis Ader drain cup 1.
  • the flange 6 can also be designed with openings 8 for a fastening 9 .
  • the drain cup 1 is designed as a pipe connection socket and assumes a cylindrical shape over a length L, which corresponds, for example, to a socket length for commercially available sewage pipe sleeves.
