The utility model discloses a be used for anchored precast concrete hexagonal piece, is concrete hexagonal piece thick 100mm 300mm, phi 300mm phi 900mm's six square body of inscribe, does concrete hexagonal piece axial direction opens have interior stepped through hole, lower extreme inner diameter of through hole phi 60mm 100mm, dark 60 200mm, the downthehole footpath phi 90mm of upper end step 200mm, dark 40mm 100mm, concrete hexagonal piece (6) use the concrete of C20 or C25 strength grade to make. The utility model provides a bank protection easily destroys and collapses and two kind big can not compromise problems of osmotic coefficient under water, has also solved the environmental issue of building stones exploitations. Simultaneously the utility model discloses simple structure, construction convenience, time limit for a project weak point, engineering cost hang down.
Description
Technical field
This utility model belongs to dyke, reservoir, navigation channel, the technical field of protective slope in canal method, the application apparatus of a kind of anchoring underwater bank protecting method, more particularly relates to a kind of precast concrete six square for anchoring.Simple in construction, easy construction, the duration is short, construction costs is low.
Background technology
At present China in water conservancy and hydropower and harbor approach and field of agricultural irrigation for preventing water from from dam, dyke, canal seepage and preventing bank protection from destroying by rush of water, since 2008 energetically investment improvement dangerously weak reseroirs, strengthen the dikes, rebuild channel, gross investment is in terms of trillion.Wherein sizeable proportion for reservoir dam bank protection overhaul with dam add cut-pff wall, on the dyke of the great rivers such as Yangtze and Yellow rivers, build bank protection, by grab bucket method and high spray and deeply stir method etc. and add cut-pff wall on dyke, its purpose is exactly to reduce dam, the seepage of dyke and prevent bank protection from destroying by rush of water and the dangerous situation that causes occurs.
Now commonly used on dyke dry code stone river bottom protection, dyke bottom dry stone pitching scheme, although the problem that river bottom protection bank protection can be solved, but because the space between stone is too many, even if there being the barrier performance of mud, the effect of the least antiseepage also can only be played.The most single stone easily collapses under the impact of current.When using concrete slab and cemented rock scheme, relatively big because of internal water pressure when the water level descends, easy avalanche during impeded drainage.And the original tiling precast concrete six square slope protection plan used because not have solution easily to destroy by rush of water, the problem of avalanche, therefore be only intended to now the bank protection top of dyke.

A kind of precast concrete six square for anchoring, including precast concrete six square, it is characterised in that:
Precast concrete six square is the inscribe hexagonal prism body of thick 100mm-300mm, φ 300mm-φ 900mm；Precast concrete six square axial centre has interior step through-hole, lower end through hole internal diameter φ 60mm-100mm, deep 60-200mm, upper end step hole internal diameter φ 90mm-200mm, deep 40mm-100mm；
Described precast concrete six square uses the concrete of C20 or C25 strength grade to make.
Described precast concrete six square thickness is 260mm；800mm, lower end through hole internal diameter φ 100mm, deep 180mm, upper end step hole internal diameter φ 160mm, deep 80mm.
Compared with prior art beneficial effects of the present invention is as follows:
Instant invention overcomes prior art defect, the prefabricated precast 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.Present configuration is simple simultaneously, easy construction, the duration is short, construction costs is low.
The present invention by putting on one extra anchor force of precast concrete six square, prevent bank protection destroy by rush of water under the effect of dynamic water current and water level decreasing internal water pressure bigger time avalanche.
The degree of compaction of the soil body is increased by squeezing into 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, limit that cement mortar when building precast concrete six square by laying bricks or stones is dry-shrinkage deformed and the precast concrete six square displacement that causes, thus eliminate temperature higher time the precast concrete six horizontal thermal expansion of square that produces damage.
The advantage of anchor is:
Bolt portion uses cast steel structure, can reduce corrosion；Utilize its slight corrosion simultaneously, increase the frictional force of anchor pole and the soil body.
Anchor pole uses cast member, make use of the distinctive surface roughness of cast member, meets the anchor force requirement of anchor pole.
Rock bolt shank uses 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, on the one hand changes water flowing direction and is not easily blocked, and not corrosion, it is also possible to absorb longitudinal avalanche damage that the soil body dilatancy inconsistent with anchor pole causes.
