SU129548A1 - Reservoir reinforced concrete dam, mainly from prefabricated elements - Google Patents

Description

The invention relates to water-soluble reinforced concrete structures, predominantly of precast elements, with bulls and towers made using high grillage of pile shells, and with a pressure face between the bulls, and between the bulls and towers formed by a wall consisting of a tongue immersed in the bottom of the river or from horizontal beams laid with the ends into the slots of bulls and abutments

In the described dam it is planned to reduce the consumption of concrete for the water part of it. This is achieved by laying the slab with a spillway surface on a bed of beams resting on the tops of the bulls' pile piles (abutments), with the upper edge of the spillway plate adjacent to the upper edge of the wall forming the pressure face.

FIG. 1 shows a plan of the base of a bull from shell casings; in fig. 2 - plan of the base of the spillway; in fig. 3 is a section along YES in FIG. one; in fig. 4 is a section through BB in FIG. 2

The proposed dam structure consists of bulls / (abutments) formed by one or two rows of vertical shell piles, straight or curvilinear in terms of a pressure face or precast reinforced concrete vertical shell piles 2, or horizontal beams 3, laid with the ends in the grooves of the bulls ( abutments), and a weir, consisting of horizontal precast reinforced concrete beams 4, resting on the top of bulls' piles (abutments) supporting slab 5. adjacent to the upper edge of the wall forming the pressure face.

The upper curved surface of the plate 5, which is a spillway, is recommended in a separate case to give such an outline that the overflow tray is thrown into the lower pool.

pa distance c. ii) Ko des Tkov. Met | Kzh, It, 1, and remove the erosion zone from the dam.

Thus, the horizontal water pressure of the upstream on the naive face of the water supply, which consists of not vertical pile-shells 2, is transmitted to the base and weir, which in turn transfers it to the buoy. The design of the pressure face in the horizontal beams 3, the eth beams directly determine the pressure of the upstream water at the terminal.

Ilpi-i location of the dam on the NSSKA.Syyuyu soil primer. The points of the weir and bulls (abutments) are immersed in it to the depth necessary for the transfer of loads on the ocnoiiauHe, as well as to ensure the stability of the dam and prevent the dam from the subfloor. . In case of an ice-cold and; | and a nonstandard base, these requirements are considerably eased and the bottom 6 shells are relieved in the basic way of drilling with the ycTpoficTBcui cementing (the blade1 of the 7 along the nanorpus front. locks. It is desirable to assign the mark of the top of the pile-shells to the ne below the water level in the non-construction period (with some reserve), which allows you to do without the construction of jumpers. The question of the design of bulls in charge of local conditions and economic considerations, in part e.; | participating in the maximum application of precast reinforced concrete (armonane structures, blocks, etc.).
