Hydrotechnical deferent tunnel with reinforced concrete lining

FIELD: construction.

SUBSTANCE: hydrotechnical deferent tunnel with reinforced concrete lining is designed as a working 1 in the rock with a cross section in the form of a figure of a constant width and in contact with the bearing reinforced concrete lining 2 with the external and the internal surfaces made in the cross-section in the form of a figure with a constant width. The cross-sections of the working 1, of the external surface in contact therewith, and of the internal surface of the reinforced concrete lining 2 are made in the form of a Reuleaux triangle. One of the coinciding corners 3 of the Reuleaux triangle of the working 1, the external and internal surfaces of the reinforced concrete lining 2 is located in the vault portion 4 of the tunnel with the reinforced concrete lining.

FIELD: ventilation.

SUBSTANCE: method involves moving of air with moving trains through the circulation ventilation connection connecting the tunnels near the subway station, and through the station. To create the desired air flow through the subway station from moving trains in the tunnel and its regulation depending on the frequency of train movement, the aerodynamic drag of circulation ventilation connection is changed.

EFFECT: lower economic costs for the ventilation of tunnels and subway stations.

FIELD: mining.

SUBSTANCE: invention concerns mining and can be used at stratum development of minerals with swelled ground rock for guarding of district development drifts. Guarding method includes implementation of district development drifts 1, fixing of district development drifts, stratum weakening of minerals be making grooves 2,3. Powers of swelling layers of minerals stratum are defined. Stratum weakening is implemented by creating of vertical rooves 2,3 in sole, in the immediate vicinity of wall of working, from side of gradient and pitch of seam, at that groove length from side of gradient 2 is accepted as equal to maximal power of swelling stratum, but not more then 2000 mm, and groove length from the side of seam pitch 3 is equal to minimal power of swelling stratum.

EFFECT: decreasing of swelling of soil rocks, decreasing of costs for supporting district development drafts, increasing of spatial work concentration, providing of easier method of groove implementation.

SUBSTANCE: corrugate tubing for load-carrying structures of underground channels comprises a corrugate metal sheet of a rectangular shape in plan, made with perforated holes on a part of the surface and having side and end stiffening ribs. At the same time stiffening ribs along the perimetre of the specified sheet are arranged in the form of metal plates arranged perpendicularly to the sheet and welded to its edges with adjacency of corrugation ends to the side surface of two oppositely arranged plates. Besides, in the specified plates there are holes for fastening bolts, and perforated holes are arranged to inject a mortar to fill cavities between corrugate metal sheets and the surface of the underground channel or the defect load-carrying barrier structure.

EFFECT: reduced weight and dimension of a tubing, lower labour intensiveness and timing of construction.

SUBSTANCE: turbine water conduit comprises an internal metal shell and an external reinforced concrete lining covered with a network of cracks of various sizes. The water conduit is located in a bottom face of a concrete dam and is rigidly fixed to the dam. The water conduit is equipped with a protective coating, which is made by application of a heat-insulating paint layer (liquid heat-insulation material) on the external surface of the reinforced concrete lining, which ensures, due to heat-insulation of reinforced concrete lining against atmospheric air, improved stressed-deformed condition of the turbine water conduit, and due to hydraulic insulation - protection of reinforced concrete lining against damaging exposure of atmospheric water. The heat-insulation paint is applied with the turbine water conduit filled with discharge water, which ensures opening of cracks on the surface of the reinforced concrete lining with its pressure.

EFFECT: high efficiency of increasing reliability of an operated steel reinforced concrete turbine water conduit.

FIELD: hydraulic structure building and repair, particularly to construct and repair power tunnels of hydroelectric plant.

SUBSTANCE: method involves forming concrete tunnel lining; consolidating ground around concrete liner by injecting grouting mortar in rock and forming damping layer between concrete lining and grouted ground. Damping layer forming between concrete lining and ground is created after tunnel filling with water under working pressure and after concrete lining curing under water pressure for 1.5-2 years. After that water is discharged and gaps between concrete lining and grouted ground are detected. Damping layer is created by plugging space beyond the lining by injecting resilient grouting mortar in spaces between outer lining surface and ground massif. The resilient grouting mortar has modulus of elasticity equal to intermediate value between that of concrete lining material El and that of ground massif Eg.

EFFECT: increased tunnel service reliability due to reduced loads applied to lining.
