WATER DRAIN TRAY

The proposed utility model relates to the design of the upper structure of the railway track, and specifically to drainage structures for the removal of surface and groundwater. The proposed design may also find application for the drainage of other structures, including roads.

Known adopted for the prototype drainage tray made of composite material - RF patent utility model No. 40059 E01F 5/00, which contains a housing in cross section of a semi-oval shape with a base and side walls, with stiffeners on the outside along the generatrix, in the side walls with drainage holes, in this case, structural thermoplastic is used as composite material, moreover, mineral-filled polypropylene or mineral-filled polyamide is used as composite thermoplastic, while the thickness of ep stiffening body defined thickness stiffeners amount determined by the requirements to the lateral stiffness drain water tray. Between them, drainage trays are connected by a detachable connection of the extreme stiffeners. Common with the proposed technical solution are the following significant features - the drainage tray is made of composite material, the housing consists of walls with drainage holes made in them, a concave base, and also stiffening ribs made from the outside of the walls and the base.

Composite thermoplastic is indeed a relatively environmentally friendly material, however, at close to boundary temperatures of the operating range of +50 -50, its physical and mechanical properties decrease very significantly, for example, in the region of the lower boundary of the working

range (-50) polyamide becomes brittle. At a positive temperature, thermoplastics have the property of high creep and irreversibility of form from a constantly acting load after backfilling with soil. Mineral fillers smooth out these shortcomings of thermoplastics, but lead to a decrease in the initial physical and mechanical properties, polyamide as a feedstock for drainage trays is of little use due to the high level of moisture absorption. In addition, the production of trays (considering their size) requires sophisticated technological equipment with a high accuracy class of work surfaces and the possibility of heating to 250-280 °, and then rapid cooling. It should also be noted that the manufacturing technology of structural thermoplastic does not allow, if necessary, to produce ribs with a thickness greater than the thickness of the skin (as indicated in paragraph 4 of the formula) - "spills" are formed. Existing known equipment for the manufacture of thermoplastic products does not allow the manufacture of sections of drainage trays with a dimension in height (depth) of the tray more than 0.5 meter. The tray docking scheme proposed in the prototype has the following disadvantages — the docking places are difficult to access and low-tech, and if it is necessary to install an incomplete tray, it is necessary to produce special “docking” trays, which must have different lengths when there are docking extreme stiffeners. A significant drawback of this design of the tray is the possibility of squeezing it out of the saturated soil by hydrostatic forces, as well as the danger of unauthorized dismantling.

The proposed utility model solves the technical problem of creating drainage trays that work stably over the entire range of operating temperatures, increase the rigidity and strength of the structure, enable the use of fairly simple technological equipment in the manufacture of trays, as well as create technological and universal docking units.

To achieve the technical result, the drainage tray is made of fiberglass and consists of a concave bottom, transverse stiffeners, made outside along the generatrix of the walls and the bottom along the entire length of the tray except for ends, longitudinal stiffeners, made outside the upper edge of the walls and transverse stiffeners, and also anchor plates located outside the tray horizontally between transverse stiffeners, while the bottom and walls of the tray at one of the ends have telescopic broadening. Additionally, to ensure the possibility of changing the shape of the route of the drainage channel in terms of the tray can be performed with rotation, which is advisable to perform with an angle of 30 ° or 45 °. To ensure the possibility of operating the trays (cleaning bottom sediments), the bottom is made with thickening (wall thickness 1.5-2 mm, and the base up to 3 mm), providing the perception of the load from the weight of the person, and the width is made based on the conditions for ensuring the passage of the person (not less 400 mm).

Distinctive features of the proposed drainage tray are the implementation of the fiberglass tray, and its walls are flat with an inclined outward direction, longitudinal stiffeners, made outside the upper edge of the walls and transverse ribs, as well as anchor plates located horizontally between the transverse stiffeners outside the tray, and there are no stiffeners along the ends of the tray, while the bottom and walls of the tray at one of the ends have telescopic broadening. Additionally, in terms of the tray can be made with rotation, the bottom is made with a thickening, providing the perception of the load from the weight of the person, and the width is made based on the conditions for ensuring the passage of the person.

Due to the presence of these distinctive features in combination with the known, the following technical result is achieved — a tray is obtained that works stably in the entire range of workers

temperatures, the strength of this tray with a similar thickness and corresponding weight exceeds the strength of the prototype (due to the presence of reinforcing fiberglass and the possibility of making ribs of optimal thickness), the strength also increases due to the presence of additional stiffeners along the top of the walls of the tray and transverse stiffeners, the flat shape of the walls greatly simplifies the formation of the tray, the telescopic connection, made in the form of an extended section of one of the ends of the tray allows you to mount the drain as quickly as possible without the use of any additional devices and materials, and if necessary, adding a length shorter than the length of the tray, it is enough to simply cut a fragment of the required size from the tray. The presence of anchor plates prevents the “surfacing” of the tray, and also provides anti-vandal protection. The implementation of the tray with rotation allows you to perform any deviations from the rectilinear direction. The presence of flat walls of the tray allows using the same technological equipment to produce sections of trays of different height (depth) dimensions. In addition, the design of the tray ensures its convenient operation by personnel.

As a result of a search by sources of patent and scientific and technical information, the totality of features characterizing the proposed drainage tray was not found. Thus, the proposed device meets the eligibility criteria “new”.

The proposed technical solution can find application in the production of drainage structures for various purposes, including drainage structures of railways and roads.

The design of the proposed drainage tray is illustrated in the figure.

The illustrated drainage tray consists of a concave bottom 1, the radial shape of which (the shape of the bottom can be performed as a radius, which can be greater than or equal to half the width of the tray along

-four-

bottom, and by pairing several radii or a curve described by a second-order equation) which promotes the effect of self-cleaning of the trays due to the gradient of flow rates, flat outwardly inclined walls 2 with drainage holes 3 made in them, transverse stiffeners 4 made outside along the wall 2 and bottom 1 along the entire length of the tray except the ends, longitudinal stiffeners 5, made outside the upper edge of the walls 2 and transverse stiffeners 4, as well as anchor plates 6 located outside the tray horizontally between the transverse stiffeners 4, while the bottom 1 and the walls 2 of the tray at one of the ends have telescopic broadening 7. Anchor plates 6 are installed on both sides of the tray in several or all sections between the ribs 4.

The above trays are made mainly as follows. Initially, the anchor plates 6, as well as the transverse stiffeners 4 with a thickness of 5 to 12 mm, depending on the size of the tray and, accordingly, the load, are manufactured by press or contact molding. The inner contour of the transverse ribs 4 is strictly consistent with the shape of the generatrix of the tray. A casing consisting of walls 2, bottom 1 and longitudinal stiffening rib 5 is molded on a snap, ribs 4 and anchor plates 6 are installed and molded at the same time. After polymerization of a thermosetting waterproof resin, the trays are removed from the mold and can be heat treated to accelerate the curing of the resin. This manufacturing method, subject to safety requirements, does not affect the health of personnel. However, at present, a more environmentally friendly injection molding method (RTM -Resin Transfer Molding) exists and is being used for the manufacture of composite fiberglass plastic, in which the binder is injected into a closed mold that already contains reinforcing material.

In place, the drainage trays are installed as follows.

A trench digging, corresponding in size to the installed trays and project documentation. Then begins the installation of trays with locking in telescopic locks. If it is necessary to lay a section of the tray, the length of which is less than the whole tray, it is trimmed to the required size, for example, with a hacksaw so that the cut line is away from the transverse rib 3. Next, the assembly is performed as usual. If necessary, trays with rotation are used. After installing the trays, filling is carried out, and then the trays are closed from above with plates - covers (usually concrete, but it is possible to manufacture and supply composite fiberglass covers). To ensure the removal of groundwater in areas of long length (more than 100m), with a slope of at least 0.002, trays of various dimensions in depth (height) are used.
