SU1335624A1 - Method of constructing canals - Google Patents

Abstract

The invention relates to the field of hydraulic engineering, in particular, to the construction of channels in a recess in bonded soils and commissioned in succession. The aim of the invention is to improve technology, shorten construction time, reduce land work. First, excavation is carried out to the design depth and width of its channel part to skip the flow of the first stage, then this part of the channel is fixed, and the freeboards 7, 8 of the channel are performed with the greatest steepness, as for temporary structures, and the channel is inserted into operation with the consumption of the first stage. Then, the excavation is done above the water level 3 by width to skip the flow of the second stage and, accordingly, subsequent queues, and the freeboards 8, 9 of channel 1 are each time performed with the highest slope for a particular type of bonded soil. 1 il.

Description

The invention relates to hydraulic construction, in particular to the construction of canals in the excavation of cohesive soils and put into operation in succession.

The aim of the invention is to improve the technology, reduce the amount of earthworks, reduce construction time.

The drawing shows a diagram illustrating the proposed method.

The diagram shows the project part of the channel 1 channel during the construction of the first stage, water level 2 when the first stage consumption passes, level 3 water when the second stage consumption passes, and the channel 4 project part of the second stage construction, level 5 water when the third stage consumption passes the project part of the channel 6 of the channel during the construction of the third stage, boards 7 of the channel, performed during the construction of the first stage, boards 8 of the channel, performed during the construction of the second stage, boards 9 of the channel, located above the channel part.

The construction of the canal, by turns, in excavations in the associated soils is carried out by earth-moving machines or hydromechanization tools. Initially, the design of the channel part of the channel 1 is made during the construction of the first stage for the passage of water flow of the first stage. The freeboards 7 of the channel, located above the water level 2, are performed with the greatest steepness corresponding to the steepness of the temporary structures, with provision of their temporary stability. After that, the channel is commissioned at the expense of the first stage.

Then, when preparing to enter part of the channel of the second stage,

development of the canal sides of the canal to obtain the design part of the canal section 4 within level 3 of water with the formation of slopes of freeboards

8 channels with the highest slope for a particular type of cohesive soils. After that, the channel is commissioned at the expense of the second stage.

In order to bring the canal to the design capacity, the canals 8 of the canal are being developed to obtain the design part of the canal section 6 within the water level 5 with the formation of freeboards 9 of the canal with the greatest steepness. Thereafter, the channel is commissioned with the design capacity and subsequent arrangement of the freeboard.

Invention Formula The method of building canals, mainly in succession in excavation in bonded soils, is different in that, in order to improve technology, reduce the amount of earthworks, shorten construction time, first produce the excavation at the design depth and width of its channel part. to skip the flow of the first stage, then fix this part of the channel, and the freeboard sides of the channel are performed with a steepness corresponding to the steepness of the temporary structures, and the channel is put into operation with the flow of the first stage, and then water dredging m above the water level of the projected width of the flow passage for the second stage and the subsequent queues, respectively, and freeboards channel each time is performed with the highest slope for a particular type of communication cohesive soil.
