Description
Technical field
The utility model relates to geotechnical engineering fields.
Background technique
Bevel edge slope landslide-proofing has very important meaning, and there are many modes for realizing bevel edge slope landslide-proofing at present, each
Have defective.
1, friction pile support technology (drill-pouring pile-type)
In current side slope, pattern foundation pit supporting structure, friction pile supporting is applied than wide.It is arranged by cast-in-situ bored pile straight line
Column, and connected by connection beam, the common structure type for resisting soil lateral pressure or Thrust of Landslide.
Friction pile is to be widely used mature piling technique.But the disadvantages such as the ability of the anti-lateral load of piles in row is low
Hinder its wider use.Its shortcomings that, mainly has：
From mechanical property angle, round stake is for resisting lateral load, under the conditions of meeting shearing resistance, the ability of resist torque
Low, main cause is that circular cross-section is not the advantageous member section of bending resistance, generally using rectangle, " work " shape etc.；Therefore, for
Engineering control is unable to satisfy at all there are large-scale, huge ground matter bevel edge slope, high cutting-slope and the deep foundation pit slope of huge thrust to want
It asks.
Economically, since anti-bending strength is poor, a large amount of reinforcing bar bending resistances are needed to configure, material use is insufficient, uneconomical.
From safety perspective, amount of deflection is big, and since stake diameter is little, slenderness ratio of pile is big, and cantilevered stake amount of deflection is big, stake tension face
It is easy cracking, influences a service life, durability is poor, to reduce safety.
Due to disadvantage mentioned above, piles in row is made to can be only applied to slope height, foundation depth less or Thrust of Landslide
Little situation limits its use scope.
2, friction pile support technology (rectangle anti-slide pile structure)
The retaining structure that landslide now, slope project are administered is widely used, is typically the rectangle antiskid of manually digging hole
Stake.The harnessing project big to Thrust of Landslide or sliding force, the often friction pile of preferred timber pile diameter.But this antiskid structure, exists
Following problem：
From mechanical property angle, although rectangular pile is used on resisting lateral load better than round stake, its resist torque
Ability it is still lower, main cause is that stake cantilever segment is the effect that Thrust of Landslide is resisted with pile body self-strength, resist
Act on very limited, displacement at pile top is big, will lead to existing buildings or structures existing for side slope top of the slope and deforms.Therefore, for
Engineering control is unable to satisfy at all there are large-scale, huge ground matter bevel edge slope, high cutting-slope and the deep foundation pit slope of huge thrust to want
It asks.
Working security is poor.
Big rectangular section friction pile, when stake depth is very big, when up to 30~40m, use is still manually digging hole technique,
Stake holes is asked to meet manually digging hole requirement, in addition retaining wall is wide, stake section is larger, and such hole hole need to take special stake holes supporting to protect
Wall means, serious accident may be led to by such as dealing with improperly.
Construction time is long, by seasonal effect.
Big rectangular section antiskid pile driving construction, due to using manually digging hole, hand excavation amount is big, low efficiency, construction seriously by
To the influence of earth excavation duration, the required construction time is long.Rainy season is met, tends not to construct, it is big by seasonal effect.It is tight to construction period
The administration project of lattice generates extreme influence.
