Abstract

FIELD OF THE INVENTION The invention relates to hydraulic engineering. The purpose of the invention is to simplify the production of work and reduce their cost and labor costs. When implementing the method, the filling of the soil layer 4 is carried out by the quarry soil from the dam 3, the height of which is determined from the condition of obtaining the fractional composition specified within the slope of channel 1 according to segregation parameters research data. The quarry soil 4 is poured in the form of heaps separated from each other, and then a part of the soil layer 4 above the design level of water in the channel is removed, and the remaining part of the layer is flattened to a predetermined slope. 1 hp f-ly, 3 ill.

The invention relates to hydraulic construction.

The purpose of the invention is to simplify the production of work and reduce their cost and labor costs.

Figure 1 shows a channel with a dam, a cross-section, without a layer of stone fastening; Fig 2 is the same with a stone mount; on fig.Z - the same plan.

The method of fastening the channel is carried out as follows.

The soil obtained during the development of channel 1 is laid on the surface of earth 2 in the form of a dike 3. In this case, channel 1 in its coastal part is developed to its full depth.

Then, from the dam 3 edge to the slope of the channel 1, the pit soil layer L. is poured. As a result of the segregation, the pit soil deposited is stratified and the stone size increases as the dam 3 edge is separated, and the lower part of the layer 4 is formed from the largest stone. In order to reliably obtain the size of stone given by the condition of the banks of channel 1, the height of dam 3 is prescribed according to field studies and the dependence of large stones on the height of layer 4, the mining of channel 4 can be used as a quarry soil at its corresponding fractional composition. In order to obtain a multi-layered fastening of channel 1 after filling the first layer 4, the height of dam 3 is increased and the process of dumping from the edge of dam 3 is repeated forming the second layer, and so on. In case of a limited amount of soil for the dam and the need

to mount a large stone to save ground volume and reduce labor costs, instead of a continuous dam 3, the necessary high heaps 5 are made, for example, of a pyramidal shape. To give a mounting surface of the required shape, which is laid at an angle of repose after reposition, it will be redesigned. At the same time, in order to avoid mixing with a small stone, layer 4 at a site above the estimated water level in the channel is previously removed.

Claims (2)

1. The method of fastening the banks of the channel, including the development of the channel, transportation and layering of the soil by dumping it from the upper edge of the bank or dams, in order to simplify production and reduce their cost, dumping is carried out with quarry soil from the dam, the height of which is determined from the condition of obtaining the fractional composition given on the limits of the coastal slope, according to the intersection of these segregation parameters, then soil dumping part of the layer above the design level of water in the channel removed, and the remaining lower part of the layer is deposited to a given slope and at the same time provide dumping with layers of uniform soil composition. 2. The method according to claim 1, characterized in that, in order to reduce labor costs, the quarry soil is poured in the form of heaps separated from each other, for example, of a pyramidal shape. figl figs
