Description

The invention relates to the field of construction and public utilities, in particular to systems of storm sewers for removal of melt water from the roadway.

It is known that the elements of the storm sewage system such as the roadbed, the sewer ring on the side of the canvas, the drainage grate on the ring and the sewer network are hierarchically interconnected and each of them affects the reliability of its functioning as a whole [1]. The reliability of the storm sewage system for the discharge of melt water into the sewer network is determined by the impact on it, as a rule, a list of a number of factors and, first of all, include the following: road-building (terrain, type of base and surface, road width quality of the project and its implementation); natural and climatic (amount of precipitation and their phase composition, differences from plus to minus seasonal temperatures, number of sunny days per year, wind rose, depth of soil freezing); environmental (degree of contamination of snow precipitation, type and intensity of traffic, type and frequency of cleaning the roadway).

Consequently, in general, to ensure reliable flow of precipitation including melt water into the sewer network, all elements of the storm sewage system must have a given capacity for them and be free from any kind of pollution (blockage). So, to fulfill such conditions, for example, technical solutions are known for removing blockages from the sewer pipelines [2] and for cleaning sediments (pollution) from the bottom of the sewer well [3]. However, with regard to the waste grate with its drain holes, the specified conditions for it are practically impossible to fulfill since the beginning of intensive (anomalous) snow melting due to the presence of solid icing on its surface and the possibility of a new icing here if the environment is removed and the temperature drops clogging of the roadway in the winter period of various kinds of waste. A close analogue of the available information on the proposed technical solution was not identified.

The objective of the invention is the provision of increased throughput of the drainage grate in the storm sewer system for the period of melt water runoff.

This is achieved by the fact that the waste grate on the sewer ring of the system is made in the form of a strong and flat in shape design with the location of the drain holes around the central window in it and in its window is placed a device in the form of a strong frame with fixedly fixed inside the row of flat plates and with fixation in it, the devices are stationary in the initial position while ensuring the possibility of rotation on the ring loops to remove it from the drain grate window and lay on its surface at the beginning of the runoff of melted water and return ARISING to its original position after the end of their flow. In another embodiment, the storm sewage system for removing meltwater from the roadway is characterized in that the flat plates of the device are double-sided sharpened like a knife along their outwardly protruding side surfaces at a width not exceeding three times the thickness of the flat plates and the device itself is endowed with the property of hydrophobicity.

The general structure of the interrelationships of the constituent elements in the structure of the waste grate as a separate system, taking into account its modification to ensure increased throughput for the period of meltwater runoff, is shown in FIG. 1, 2 and 3.

So in FIG. 1 shows a waste (trash) grate 1, as a subsystem of a storm sewer system, in the form of a flat structure made of a durable material, such as cast iron, with the arrangement of drain holes 2 around the central window 3 on it. The area of the window 3 in the waste grate 1 is two times larger than the total area of the drain holes 2 on the grate 1 itself.

In the window 3 of the waste grate 1 with the support on it is placed as its parts (Fig. 2) a device in the form of a frame 4, for example made of steel, with a number of flat plates 5 with a thickness up to 4 mm fixed inside its frame 4, for example by welding. In the initial stationary position, the device in the form of a frame 4 is connected with the drain grate 1 by means of two annular loops 6 (Fig. 2, 3) through holes in them while fixing the latter on their threaded ends with the help of nuts 7.

From practice (for example, walking in ice, skating) it is known that in the zone of contact of a solid with ice (ice) with a high level of specific pressure between them there is ice melting, i.e. the formation on it of a thin layer of water, depriving them of adhesion to each other. In this regard, the implementation of the outer side surfaces of the flat plates 5 in the device (Fig. 2) in the form of a frame 4 with double-sided sharpening like a knife makes it easy to remove frost from them and this is facilitated by the endowment of the device as a whole with hydrophobicity, for example, by painting with a hydrophobic composition.

The use of the proposed construction of the waste grate 1 in the storm sewage system is preferably on sewer manholes with their location in low-lying places on the side of the roadway of the sewer network, where it is possible that there is so much wastewater that does not meet the throughput of the drain grate 1 (Fig. 1 ) only with a set of drain holes 2 on it.

With the onset of the beginning of the runoff of melt water, the device in the form of a frame 4 is turned off by means of a folding handle 8 (FIG. 2) by rotating the loop loops 6 from the window 3 (FIG. 1) of the drain grate as its initial position on the surface of the drain grate 1 and after their drain it returns to its original position.

The proposed technical solution has the following advantages:

- the possibility of rapid modification of the drain grid system for a sharp increase in throughput;

- ease of operational use without the cost of material resources.
