The Design of the Mouth of the Drainage System and the Fastening of the Cross-Section of the Stream

The purpose of the work is to develop the design of the mouth of the drainage system and the fastening of the cross-section of the stream of the first stage of construction of the military-patriotic park of culture and recreation of the Armed Forces of the Russian Federation “PATRIOT”. The article presents a new design of the mouth structure in the drainage system and the fastening of the cross-section of the stream. The proposed design of the mouth will improve the quality of drainage waters discharged into the intake by reducing the flow rate of water in the gravel deposit, as suspended particles will precipitate. In addition, over time, green algae form on the surface of individual fractions of crushed stone, which, by absorbing substances dissolved in water, purify it. The article proposes a new design for fixing a cross-section of a stream capable of intercepting pressurized groundwater in places where it is wedged out to prevent the leaching of fine earth, which contributes to the formation of sinkholes and the collapse of stream slopes. The uninterrupted operation (2015-2025) of the mouth structure in the drainage system and the fastening of the cross-section of streams proves their good operability and adequacy of the developed technical solutions. It is shown that during the construction of mouth structures in drainage systems and cross-sectional anchorages of watercourses carried out in the 21st century, it is necessary to use the experience of previous generations in the design and operation of mouth structures in drainage systems, as well as cross-sectional anchorages of watercourses, and the use of new more advanced and environmentally beneficial solutions.
