Technical field
The present invention proposes a kind of cast-in-place anchor of bore liquid companding large netting cage reinforced for natural slope or Artificial Side-slope
Solid construction head and its construction method.The drilling construction head carry iron wire cylinder mould drilling side slope face to set depth after,
Expanded support can be carried out to neighbouring iron wire cylinder mould, during drill bit is above carried so as to greatly increase the anchoring face of anchoring body
Product and reinforcement area, enhance the skid resistance of side slope, it is to avoid due to the reduction of shearing strength inside side slope or external force influence
The geological disasters such as slope instability, the mud-rock flow for destroying side slope stress equilibrium and causing, improve the stable security of side slope.This
Invention make drilling, slip casting, lay iron wire cylinder mould and expand cylinder mould realize integration, can apply to nature soil-slope or
Person newly excavates the Artificial Side-slope filled, improves factor of safety against sliding, reduces geological disaster risk, belongs to civil construction project and rock
The correlative technology fields such as geotechnological journey.
Background technology
The either side slope of natural slope or hand excavation's landfill, all probably due to the reduction of internal shearing strength or
Occur the geological disasters such as mud-rock flow, landslide, progressive slump under the effect of the external force such as rain drop erosion, slacking, earthquake.Soft viscous
Soil area, especially in the case where vegetation deterioration is more serious, easily forms mud-stone flow disaster after precipitation.Therefore in civil construction
In engineering, slope reinforcement problem is inevitably run into.In current slope reinforcement measure, generally using domatic grid and
Set the methods such as anchor pole to be reinforced, but empty in long-term rain drop erosion, under gravity creep phorogenesis, grid block holds
The destruction that comes off is easily caused, anchor pole also easily causes failure because of corrosion.Simultaneously because the anchor hole that rig is got out at present is general all
It is cylindrical, diameter is smaller, the withdrawal resistance of anchoring body for causing it to be formed is smaller, deforms larger.Therefore a kind of energy of invention is considered
Enough expand the cast-in-place anchor construction head of cylinder mould and its construction method, so both can act on forming irregular anchor by expanded support
Hole increases the withdrawal resistance of anchoring body, can also prevent reinforcing body from, by corrosion, improving the overall steady of side slope by cast-in-place effect
It is qualitative.
