Protection of gabions from destruction

  Protection and stabilization of the pipelines located on underwater passages can be performed with pipeline deepening to reservoir bed followed with the crushed stone pouring. However even on the flat rivers during a flood most part of crushed stone is washed out downstream. The repeated pouring of pipeline with crushed stone not only raises total costs on pipeline protection, but also harms the fauna of reservoir.


For prevention of the washout of the crushed stone special reticulated baskets are widely used nowadays, so-called gabions. Unfortunately, crushed stone piling on the pipeline of underwater passage with the use of gabions is rather labor-consuming and does not always provide quality of protection to under-water object even if supervised by highly-professional divers.

But this most not dangerous. Other substantial drawback of "crushed stone baskets” is recently discovered.

  The river flow constantly transfers the vast amonts of sand. Sand constantly outwears wire framework. During a year the natural sand-blast setting rips off plastic or anodized coverage from wire framework, opening the way to metal corrosion. For protection of "crushed stone baskets" from destruction, flexible concrete mates must protect gabions  on each side from a contact with a natural “sand-blas”t. And, at last, pipeline  protection made form the crushed stone or Reno mates is extremely difficult to remove, if pipeline repair is required.


And Universal flexible protective concrete mates are easily dismantled and moreover, after completion of repair works, UFPCM can be piled back.

 Long-term experience proved the efficiency of the combined protection of bridge footing, when the river banks are protected with gabions and the most sufficient areas of river-bed - with Universal flexible protective concrete mates (UFPCM).

On the rivers with depth of less than 1,0 m works on UFPCM piling are done with the use of traditional constructing machines.

When UFPCM are piled directly under bridges, which practically lie on water, winches are used. With a winch UFPCM are dragged through the river-bed to the place of piling and then positioned. Durability of fastening armature rope allows to do so. 

UFPCM piling is done similarly to the technology of piling of mates on middle depth. If the combined system of protection is used, the most important part is the safe fastening of UFPCM linen with gabions. The best way is when gabions are set on UFPCM linen.
