Compared with prior art beneficial effects of the present invention is as follows:
Instant invention overcomes prior art defect, the Prefabricated Concrete six square bank protecting method of disclosed a kind of anchoring and application apparatus thereof.Reach to solve underwater slope protection easily to destroy by rush of water avalanche and the big two kinds of problems that can not take into account of infiltration coefficient, also solved the environmental issue of exploitation of stone.Simultaneously present configuration is simple, easy construction, the duration is short, construction costs is low.
The present invention is by putting on one extra anchor force of precast concrete six square, it is prevented that avalanche when bank protection destroys by rush of water under the effect of dynamic water current and water level decreasing internal water pressure is bigger.
By the degree of compaction squeezing into the increase soil body of anchor pole, the layer of holding one's breath higher than dyke body degree of compaction is formed in bank protection face, reduce the seepage of dyke, simultaneously by change former water-through and ventilating straight hole be the version being folded to hole, make full use of the sealing property after carrying mud sediment in water, while being not easily blocked, reduce the seepage of water on bank protection face.
By being pressed in the anchor pole on precast concrete six square and the frictional force between precast concrete six square, restriction cement mortar is dry-shrinkage deformed when building precast concrete six square by laying bricks or stones and the precast concrete six square displacement that causes, thus eliminate temperature higher time the precast concrete six square transverse direction thermal expansion that produces damage.
The advantage of anchor is in that:
Bolt portion adopts cast steel structure, can reduce corrosion；Utilize its slight corrosion simultaneously, increase the frictional force of anchor pole and the soil body.
Anchor pole adopts cast member, make use of the distinctive surface roughness of cast member, meets the anchor force requirement of anchor pole.
Rock bolt shank adopts uiform section, does not produce space at anchor pole and soil body binding site.
Rock-bolt length can according to design anchor force need increase length.
Nylon water flowing pad, changes water flowing direction and is not easily blocked on the one hand, and not corrosion, it is also possible to absorb longitudinal avalanche damage that the soil body dilatancy inconsistent with anchor pole causes.
