Abstract

HYDROTECHNICAL CONSTRUCTION, containing a dam with a water inlet: a bore hole blocked by a flybet and a jumper with a counterweight and automatic level control of water level in the channel, and a bridge with a span structure mounted on a horizontal axis. Characterized by the fact that, in order to reduce the material consumption and the weight of the structure, the jumper is made in the form of a plate, mainly of rubberized sheet attached to the frame, anchor supports are fixed in the flybet, and the flying structure is rigidly connected to the jumper.

; The invention relates to hydraulic structures and can be used on canalshah, preferably drainage, to regulate the level of water in them.

A hydraulic engineering structure for Kanshov is known, which contains a dam with culvert openings with overlapping bridges supported on flybet and hinged to the walls bearing the bridge span structure with the possibility of turning about vertical axes. The presence of such bridges allows one to ensure the passage of the construction of maximum water flow rates in the spring half of the territory. Through opening of the holes, the bridges turn to the walls of the bridges to the walls

However, walls with bridges loose the structure, and when skipping costs, the flood is in the watercourse and thus causes a decrease in the capacity of the structure.

A hydraulic structure containing a dam with a culvert opening is known to be overlapped by a bridge with a counterweight and an automatic water level control in the channel, which is rotatably mounted on a horizontal axis, and a bridge with span structure C23.

The disadvantages of the known structures are large consumption of materials and weight,

The purpose of the invention is to reduce the consumption of materials and the weight of the structure.

This goal is achieved by the fact that in a hydraulic structure containing a dam with a culvert opening that is blocked by a flybet and pivoted on a horizontal axis with a jumper with a counterweight and an automatic water level regulator in the channel, the bridge with a span structure is made in the form of a plate, mainly from the rubberized sheet attached to the frame, anchor supports are fixed in the flybet, and the flying structure is rigidly connected to the lintel.

Fig, 1 shows a hydraulic structure, general view, longitudinal section; in figure 2 - the same, in a position that ensures the passage of water flow in the spring flood, in fig. 3 - section aa in figure 1 in figure 4 - section bb in figure 3 (side edge of the lintel on anchor support .re). ,

The hydraulic structure has a jumper 2 installed on the flybet 1 with a hole in its lower part through which the lower one is passed.

a branch of the siphon 3, located in the upstream, and the superstructure 4 of the Pedestrian Bridge with pile coastal supports 5.

Flutebet 1, extending along the bottom and slopes of the channel, is made of reinforced concrete with anchor supports b, the jumper 2 is in the form of a trapezoidal waterproof plate, for example of a rubberized woven sheet attached to a light trellised frame. The lateral edges of the pc1ma are fixed on the anchor supports b, which take up loads from the jumper tension under the pressure of water on it from the headwater. At the same time, due to the tilting in horizontal section of the supporting faces 7 (figure 4), both the reliable fixing of the jumper and separation from the anchor supports after dewatering.

The hub 2 is rigidly connected by means of rods 8 to the span 4 of the bridge, which is made in the form of a reinforced concrete block pivotally attached to the supports 5 and can be rotated manually (using the simplest means) about the horizontal axis 9, and this block serves as a counterweight to the mass of the jumper and siphon 3. Lastly, a predetermined level of water in the canal (upstream) is automatically maintained.

To set the automatically maintained water level, the siphon 3 is connected to the arm 10 of the lever pivotally attached to the rods 8, and the output part of the downstream branch of the siphon is curved in an arc centered on the horizontal axis 11 of the lever rotation. The other lever arm 12 is movably articulated with a screw lift fixed to the span 4, which is mounted on the support 13 with the possibility of its cargo screw 14 being vertically moved in the guide rail 15. A bucket is attached to the rods 8 and the bridge 2 on the downstream side. 16, for discharging, there is an air pipe 17 attached to the top of the siphon with the possibility of flooding the inlet end of the tube with water when the supported level is exceeded.

The automatically maintained water level of the headwater is set during the growing season (summer-autumn) period from the screw elevator by means of a corresponding rotation of the siphon 3. In Fig. 1, the siphon is shown in the position at which 1 the normal retaining i level 18 is maintained and the dashboard lines show the position in which

the siphon is rotated to maintain a lower level of 19.

When the preset level is exceeded, a water overflow occurs and the cat 16 is filled by the siphon at the same time. At the same time, by raising the water level in the upstream side, the inlet end of the air guide tube 17 is submerged, which prevents air from entering the siphon. This provides for the charging of the sno-phon by removing the air from the siphon cavity with a stream of water flowing over the ridge, and discharging the water of the siphon from the upstream to the downstream. After the preset water level has been restored, air flows through the inlet section of the air tube to the siphon, which discharges the siphon.

After the growing season, the span structure 4 of the bridge, together with perekichka 2 attached to it (in the absence of water pressure on it), is turned about the axis

9 to the position shown in FIG. 2, and the ds are carefully attached to the shore supports 5 for the safe passage of pedestrians across the bridge. In the etsm position, a jumper with automatic CIM adjusting the water level (siphon 3} is out of the channel, above the calculated maximum level 20 water in the spring flood, so that the flow flood freely passes 5 through the channel, not constrained by the elements of the structure.

The invention will provide a reduction in the weight of the device and the exposure of the metal and material for the construction. wives .
