Description
Technical field
The utility model is related to foundation pit or slope excavating supporting construction, the overhang mill knot of anchor specifically after a kind of band
Structure.
Background technology
In foundation pit or slope excavating support engineering work progress, cantilever soldier piles, double-row pile, stake-anchor, stake-support supporting knot
Structure is current widely used vertical cut support system.Wherein cantilever soldier pile retaining structure applies in general to cutting depth
Smaller foundation pit or slope project, because its stake top is without constraint, Horizontal Displacement is bigger than normal after excavation；To meet stability against overturning
It is required that the build-in segment length that its underpart is buried according to related specifications is not less than 0.8 times of excavation of foundation pit depth, that buries is embedding
Gu segment length is larger.Retaining Structure with Double-row Piles lays the closeer campshed of two rows of distributions along foundation pit or side slope periphery, and campshed stake top is set
Big rigidity coupling beam two-way in length and breadth is equipped with, the stake of front and rear campshed is long general identical, compared with cantilever soldier pile retaining structure, double-row pile
Supporting construction has many advantages, such as that rigidity is big, horizontal displacement is small；But its cost is relatively high, is generally used for no anchor cable (bar) or interior
Under the execution conditions of support.Stake-anchor supporting construction is that one or multi-channel prestress anchorage cable is vertically set on the pile body of campshed
(bar), anchor cable (bar) are generally connected with stake using waist rail, this-anchor supporting construction disclosure satisfy that the larger foundation pit of cutting depth or
The requirement of slope excavating engineering, and have many advantages, such as that rigidity is relatively large, horizontal displacement is relatively small；But one fixed width after stake
