Abstract

The invention relates to hydraulic structures and reduces the material consumption of the structure. The shipping gateway consists of a chamber 1, bounded by the top and bottom heads. Upper gateway head is equipped with working and emergency gates. Lower head is equipped with working and repair gates. The walls 8 of the chamber 1 are made with longitudinal trapezoidal cavities. Cavities 9 have a wide base, facing the backfill 10, and a narrow base toward the chamber. They are used as savings pools, and the cavities 1, facing the broad base towards chamber 1, and narrow toward the backfill 10, are filled with air. 4 il. // (L with o 00 o o

Description

The invention relates to hydraulic structures.

The purpose of the invention is to reduce the material consumption of the structure.

FIG. 1 shows shipping 1ylyuz. plan view; in fig. 2 shows section A-A in FIG. 1 (along the axis of the gateway gauge); in fig. 3 shows a section BB in FIG. 1 (on the wall of the sluice chamber); in fig. 4 shows a section B-B in FIG. 1 (on the walls of the chamber).

The pressure of water from the side of chamber 1 is compensated for by the active pressure of the filling soil and the moment of its own weight of water in the chamber transferred to the bottom walls. When emptying the chamber 1 to the level of the lower reach, the cavity 9 is filled with water, facing the wide side toward the backfill 10. This results in a moment of force directed against the active pressure of the backfill 10, which allows the FLOOD gateway to consist of a chamber walls 8 are equally limited upper 2 and lower 3 heads. The upper head 2 of the airlock is equipped with working gate 4 and emergency gate 5. The lower head 3 is equipped with working gate 6 and repair gate 7. The walls 8 of chamber 1 are made with longitudinal trapezoidal cavities, while the cavities 9 have a wide base facing the backfill 10, and the narrow side toward the chamber, are used as savings pools, and the cavities 11, 20 facing the broad base toward the chamber 1, and the narrow base toward the backfill 10 are filled with air. At the base of the walls 8, drainage is laid 12, and along the contour of the base of the walls, both from the side

dimensional stresses. The soil backfill level 10 is selected so that the active pressure of the soil compensates for the hydrostatic pressure on the walls and bottom in the filled chamber, and the volumes and dimensions of the cavities 9 are selected so that the moment of force arising from filling it with water with respect to the center of the wall 8 backfill pressure 10.

Claims (1)

Invention Formula Ship gateway containing upper and lower heads with gates, concrete walls of the chamber with backfilling and placing 10, and on the side of the bottom 13, the savings banks in them are seawater lines 14. With sides that have a trapezoidal downstream A tongue-and-groove pitch of 15. N-section shape is installed, as well as a bottom, with the presence of filtering soils in the area of the upper head 2, a tongue-and-groove pitch 16 is established on the side of the upper pool. Drainage 12 is connected to the upper pool by the conduits 17. the tail run through the walls 18. Between the bottom 13 and the walls 8, expansion joints 19 are made with seals 20. The shipping gateway works as follows. When the water level in chamber 1 is equal to the level of the upstream, the cavity 9 and the cavity 11 are filled with air. Drainage 12 provides the level of the upper pool, which ensures the weighting of the walls 8. At the base of 40 research institutes of the walls, they provide uniform stresses to the weight of the wall, while hydrostatic concrete walls of the chamber are separated from the bottom by deformation slots, characterized in construction capacity, it is provided with a drainage laid at the base of the walls throughout their area, to which water lines are led from the headwaters, and along the contour of each wall, there are tongue-and-groove rails installed at its base, savings pools are located they base trapezium towards the backfill chamber walls and narrow - in the direction of the camera, the savings between the basin has the same trapezoidal sectional air cavities in which the wide base faces towards the camera and narrow - in the direction of the backfill. 35 5 2 ij The pressure of water from the side of chamber 1 is compensated for by the active pressure of the filling soil and the moment of its own weight of water in the chamber transferred to the bottom walls. When emptying chamber 1 to the level of the downstream, the cavity 9 is filled with water with its wide side facing backfill 10. This results in a moment of force directed against the active pressure of the backfill 10, which allows to maintain uniform stresses at the base of the walls 8. The soil backfill level 10 is selected so that the active pressure of the soil compensates for the hydrostatic pressure on the walls and bottom in the filled chamber, and the volumes and dimensions of the cavities 9 are selected so that the moment of force arising from filling it with water with respect to the center of the wall 8 backfill pressure 10. Invention Formula nominal section of the form, as well as the bottom, 0 the concrete walls of the chamber are separated from the bottom by deformation joints, characterized in that, in order to reduce the material capacity of the building, it is provided with a drainage laid at the base of the walls throughout their area, to which the water lines are led from the upstream side in its base, there are installed tongue and groove rows, the savings pools are located by a wide trapezium base towards the backfilling of the chamber walls, and narrow ones - towards the chamber, while the same trapezoidal lines are located between the savings pools section of the air cavities in which the wide base faces towards the camera and narrow - in the direction of the backfill. five 6 d L1 18 13 B rm Riga.1 9ig.2 / 7 t ///////////////// x / y 12 75 (Rig.
