Description

Изобретение относится к гидротехническому строительству, в частности к строительству каналов.The invention relates to hydraulic engineering, in particular to the construction of canals.

Известен канал, включающий дно и боковые стенки с выступами [1].Known channel, including the bottom and side walls with protrusions [1].

Известен также канал, включающий дно, откосы и закрепленные вдоль русла гибкие элементы [2].Also known channel, including the bottom, slopes and fixed along the channel flexible elements [2].

Однако известные устройства не обеспечивают защиту неукрепленных откосов.However, the known devices do not provide protection for slopes.

Цель изобретения - предотвращение размыва откосов.The purpose of the invention is the prevention of erosion of slopes.

Поставленная цель достигается тем, что гибкие элементы выполнены в виде полотнищ, верхняя часть которых снабжена поплавками, а нижняя - закреплена к дну.This goal is achieved in that the flexible elements are made in the form of panels, the upper part of which is equipped with floats, and the lower one is fixed to the bottom.

На фиг.1 изображен канал, поперечный разрез» на фиг.2 - то же, продольный разрез.In Fig.1 shows a channel, a cross section "in Fig.2 is the same, a longitudinal section.

Канал включает днище 1, неукрепленные откосы 2, гибкие полотнища 3, снабженные поплавками 4 и закрепленные к дну 1 при помощи якорных устройств 5.The channel includes a bottom 1, unfastened slopes 2, flexible panels 3, equipped with floats 4 and fixed to the bottom 1 using anchor devices 5.

При работе канала гибкие полотнища 3, установленные у основания -» откосов 2, гасят поперечные цирку5 ляционные скорости потока и предотвращают размыв откосов 2 и деформацию русла канала, что позволяет исключить крепление откосов 2.When the channel is operating, the flexible panels 3 installed at the base of the slopes 2 quench the transverse circulation velocity of the flow and prevent the erosion of the slopes 2 and the deformation of the channel of the channel, which makes it possible to exclude the fastening of the slopes 2.

Claims

The invention relates to hydraulic construction, in particular to the construction of canals. A known channel includes the bottom and side walls with protrusions 1}. A channel is also known, including the bottom, slopes and flexible elements 2 fixed in the channel. However, the known devices do not protect unfortified slopes. The purpose of the invention is to prevent erosion of slopes. The goal is reached that the flexible elements are made in cloths, the upper part of which is removed by float, and the lower part is fixed to the bottom. Figure 1 shows the channel, the cross-section in figure 2 is the same, longitudinal section. The channel includes the bottom 1, unfortified slopes 2, flexible panels 3, fitted with floats 4 and fixed to the bottom 1 by means of crusting devices 5. When the channel operates, the flexible panels 3 installed at the base of the slopes 2 extinguish erosion of slopes 2 and deformation of the channel channel, which eliminates the mounting of slopes 2. Formula of the invention The channel, including the bottom, slopes and flexible elements fixed along the channel, characterized in that, in order to prevent slope erosion, flexible elements s are formed as webs / the upper part of which is provided with floats, and the bottom - is attached to the bottom.
