    摘要: A self-cleaning dosing pump system for delivering a slurry of solid particles and water. The dosing pump system comprises a membrane metering pump (10) and at least one sieve (11-13), arranged at the delivery end of the pump (10). The invention is particularly applicable to delivering a slurry of microsilica to a spray nozzle (5) for shotcreting.

    摘要: A production method for fabricating a concrete pillar or beam, in which method the concrete mix is sprayed against the wall of a mold (1, 2, 3, 4, 5) having a predetermined shape, after which the concrete surface is smoothed by levelling. The concrete surface is levelled with the help of a surfacing disc (6), whereby the pillar or beam is rotated so as to place one side of the pillar or beam at a time facing the surfacing disc so that the pillar or beam achieves a section of a square, rectangle, pentagon, hexagon, or a similar forn.

    摘要: A large diameter reinforced concrete section, such as a culvert or pipe is formed by mounting a mould core (20) on a spindle (23) for rotation. The exterior surface of the mould has a shape which is the required interior shape of the section to be formed. A mesh of reinforcing rods (26) is then wrapped around the core (20) and concrete is sprayed from a gun (24) onto the core while it is rotating. The concrete includes a setting accelerator which ensures rapid setting of the concrete on the core. When set, the core is removed. In this way sections can be formed quickly and with a minimum of labour.
