scope:

This standard applies to the design of hydraulic steel structures comprising the steel structures themselves, their associated machinery and their electrical equipment. These structures comprise gate bodies with seals and bearings, drives and elements connecting gates and drives.

This standard applies to newly built hydraulic steel structures. If this standard is to be applied to the partial reconstruction or the repairing or altering of existing older structures, the specific elements to which the standard applies shall first be stated and agreed upon.

This standard also covers inspection gates and equipment such as intake trash rakes, recessed bollards, floating bollards, impact protection installations and canal bridges. It may also be applied by analogy to pressure pipes and their fittings.

It does not apply to dolphins, lead-in jetties, waterfront structures, landing stages and off-shore structures (e.g. off-shore platforms and lifting platforms).

When designing small gates subject to minor loads (i.e. less than 50 kN for water pressure (in kN/m2) acting on the skin plate), the requirements of this standard need not be complied with if the client so agrees.

The specifications relating to steel structures shall apply to structures subject to loads due to still or flowing water. They cover both the movable gates and the fixed parts (i.e. parts that are firmly connected to the solid structure), such as sleepers and contact faces. Structural steelwork erected in conjunction with hydraulic steel structures, but not subject to loading due to water pressure, shall be designed and constructed as specified in the relevant regulations or codes of practice.

The specifications in this standard relating to machinery as in this standard cover the machinery required for moving or supporting gates, e.g. gudgeons and pintle bearings. They also comprise mechanical and hydraulic drives (i.e. drives using oil as the fluid for power transmission), manual and auxiliary drives, machine housings and frames, covers of gate shafts under pressure, wheels and guide rollers and their rails, dogs, plain bearings and locking mechanisms for gates and connecting elements such as chains, ropes, pinion racks, tooth racks and linkage elements. Pins for connecting machine components to steel structures and axles (including the associated bores) shall be regarded as machine components for the purposes of this standard.

NOTE 1 See DIN 4048-1, DIN 4048-2 and DIN 4054 for terminology relating to water engineering in general. Further specifications relating to dams are given in DIN 19700-10, DIN 19700-11, DIN 19700-12, DIN 19700-13, and DIN 19700-14.

NOTE 2 The term "oil" (oil-hydraulic drives) is used to mean all pressure media (fluids) that are suitable for the operation of hydraulic systems.
