Abstract

I. the invention relates to hydraulic construction, in particular to water U / 7 prefabricated structures, and can be used by taking weight from Bepxiiei about the downstream hydraulic structure. The purpose of the invention is to demonstrate the efficiency of work under conditions of a scheduling. The swift turn includes a curved tray 1 with side walls: concave 2 and convex 3, and a bottom made as separate CTyncHeii 5 with straight front edges (and concave side edges 7. Turns with curvature on timber flooding It reduces the dynamic effects of water and forest on the concave wall 2 of tray 1 by means of a wall, 1 side of the side discharge of the stream from the concave rpaHcii 7 steps 5 above the front, and also due to the location of the lower side 8 below the level downstream. 5 IL .

Description

The invention relates to sidotekhnicheskoe construction, in particular to the water discharge facilities, and can be used for rafting timber from the upstream sidrotechnicheskih construction to the downstream.

The aim of the invention is to improve the performance of timber floating.

Fast) with curved m. 15 includes curved 1 in plan in terms of tray 1, has a concave side wall 2, a concave side wall 3 and bottom 4 in the form of individual steps 5 adjacent to the convex side wall 3 of tray 1 with a straight front edge 6, concave the lateral face 7, which are smoothly mated with the concave side wall 2 of tray 1, in this case the lower runner 8 is located below the ure15 of the lower reach (not (rendered)).

The bottom 4 of tray I due to the steps 5 has a lowering to the side wall 3 unnumbered, and the steps 5 have a direct inclination towards the lower side, equal to 1 у, the trunk of the entrance part 9 "of the skein 1.

In terms of tray 1, it is redistributed without expansion of the jets due to the considerable length of the concave 1 7 steps 5 and the main alignment of the grain 7 with the concave side wall 2 of the tray 1, the speed design in the case of its erection. yosenlavnyh watercourses will ensure the dynamic effect of water and wood on the concave wall 2 of tray 1 due to the predominance of lateral discharge of the stream from the concave faces 7 steps 5 above the frontal drain from the faces 6, as well as due to the location of the lower stage 8 lower level downstream.

Claims (1)

Claim Quick turn with a turn, including a curved tray in plan with a concave and convex side walls and a bottom, made with a decrease to the convex side wall and towards the downstream. characterized in that, in order to increase work efficiency in the conditions of timber rafting, the bottom of the tray is made in the form of separate longitudinal steps, each of which is installed in the direction of the downstream with a direct slope equal to the slope of the input part of the tray, and made with a rectilinear adjacent to the convex wall of the tray a frontal face radially located relative to the axis of the tray on a part of its width, and with a concave side face that smoothly mates with the concave side wall of the tray, while the lower stage is located below the level of the lower F. fig.Z GG fi 5
