Torkret installation SО-49PBN (Pneumatic concrete pump)
Torkret installation SO-49PBN designed for pneumatic conveying
and applying fine-grained concrete mix (sand concrete) on various
surfaces (air concreting).
Air concreting is a type of concreting method of air supply and application of concrete mixtures, including also a way of shotcrete.
The difference between air concreting of other ways of shotcrete
is that the mud channel is transported in suspension and are deposited
using the nozzle to the surface at a speed of 70-90 m / s concrete
mixtures with fine-grained filler.
Torkret installation SO-49PBN used for repairs and construction of buildings and structures, namely:
- construction of reservoirs, tanks, towers;
- construction, waterproofing and repair of hydraulic structures;
- construction of the railway and auto tunnel;
- mount construction pits;
- mount rocky slopes;
- strengthening the structures of masonry and concrete;
- construction of domes, shells of positive and negative curvature;
- construction of thin walls and walls of the rigidity of industrial buildings;
- protection of underground facilities;
- corrosion protection of steel structures;
- restoration of the protective layer of concrete;
- application of wear-resistant coatings;
- elimination of defects of concrete structures;
- repair of tunnel coatings, cooling towers, bridges, etc.
Advantages gunning install SO-49PBN:
- still given water cement ratio, which is one of the main factors bedded concrete;
- small dusty workspace;
- loss of rebound is reduced to 4-6%;
- labor costs are reduced by 20-30%.
