Name of product. Water drainage trays are designed for the permanent collection and removal from the railway track of surface and partially underground waters located in the upper layers of the soil.

Defined indicators:

Appearance.

Geometric parameters and dimensions of trays:

  • Depth (H);
  • Length (L);
  • Width (W).
  • Allowable deviations in basic parameters and dimensions.
  • The deviation from the perpendicularity of the end should not exceed 10 mm at a length of 1000 m of the side of the cross-section of the tray.

Narrowing of trays I (*) type under the action of distributed, short-term, concentrated loads.

Narrowing of trays II (**) type under the action of distributed, short-term, concentrated loads.

Change in width of drainage chutes in the loaded state.
