Description
Technical field
The present invention relates to a kind of stand column pile installation method, and in particular to one kind is applied to cut cement soil continuous wall in canal formula
Or the stand column pile installation method constructed in boulder bed applied during cement-soil stirring pile construction.
Background technology
In order to ensure underground structure and foundation ditch surrounding enviroment safety, it is necessary to foundation pit side-wall and around using support, plus
Gu etc. safeguard procedures.Building foundation pit supporting generally include around margin of foundation pit set enclose purlin beam and it is some be arranged on enclose purlin beam it
Between horizontal shore and stand column pile constitute.Stand column pile is connected provided with support supporting piece constitutes supporter, for supporting in foundation ditch
Vertical load and moment of flexure that horizontal shore is transmitted.
The stand column pile of current foundation ditch is typically to be constituted using shaped steel, and shaped steel is pressed into structure in foundation ditch by the way of piling
Into the stand column pile for supporting horizontal shore；But for boulder bed, it is more than 30 centimetres of erratic boulders especially in the presence of more
In the foundation ditch on continental deposit stratum, current this column pile construction method is difficult to apply, and construction reluctantly is also difficult to ensure that stand column pile
Stability.In view of this, how to design a kind of preferably in boulder bed and can be mixed with the stratum of erratic boulder and carry out stand column pile
Construction be necessary.
The content of the invention

Stanchion, and the displacement soil produced during canal formula cutting cement soil continuous wall or cement-soil stirring pile construction can be subject to profit
With environmental protection is conducive to, the energy and resource are saved.
Importantly, because canal formula cuts the displacement produced during cement soil continuous wall or cement-soil stirring pile construction
Soil not only in cut cement soil continuous wall or Soil-cement containing the cobble in the layer of original place, husky and clay, and containing canal formula
The cement of stake（Cement content reaches the native mass percent 20%-25% of displacement, and cement stirs with cobble, husky and clay）；
Compared with common concrete, not only there is the displacement soil cobble in the sticky consolidation of cement, and displacement soil also to have
There is certain skeletal support effect, thus reliable fastening i.e. support is formed replacing the stanchion that can be opposed after soil solidifies, so that
Horizontal shore is transmitted in effectively supporting foundation ditch vertical load and moment of flexure.
Preferably, stand column pile is the square tube that cross section is square, the stand column pile is vertically auxiliary provided with rotary and telescopic
Help supporting mechanism, the vertical auxiliary support mechanism of rotary and telescopic include the vertical axles being rotatably provided in stand column pile and
Two be arranged on stand column pile bottom telescoping support structure, and two telescoping support symmetrical configurations are distributed in the phase of vertical axles
To both sides, the telescoping support structure include being arranged on vertical supporting plate in stand column pile bottom, it is some from bottom to top successively
The transverse horizontal supporting plate that is distributed on vertical supporting plate and it is some be arranged on stand column pile side and with transverse horizontal supporting plate one
One corresponding guide through hole, the vertical supporting plate and parallel, the transverse horizontal in stand column pile side where guide through hole
The end of supporting plate passes through corresponding guide through hole；The vertical axles are provided with least one expanding structure, expanding structure position
Between the vertical supporting plate of two telescoping support structures, expanding structure includes two horizontal braces being arranged in vertical axles
Bar, and two triatic stays are symmetrically distributed in vertical axles both sides；Also include A1 steps between the step A and step B：
A1：Rotating vertical axles makes triatic stay parallel with vertical supporting plate, then that transverse horizontal supporting plate is past vertical
Elapsed in stanchion, untill vertical supporting plate is resisted against in vertical axles；
It is further comprising the steps of after the step C：
D：Vertical axles and triatic stay are rotated, vertical supporting plate is strutted by triatic stay, so that by transverse horizontal
Supporting plate is toward extrapolated, untill vertical supporting plate is resisted against the medial surface of stand column pile.
Preferably, the upper end of vertical axles is located in the top of stand column pile, vertical axles, set above stand column pile
Have in horizontal inserted link through hole, the horizontal inserted link through hole and be inserted with action bars.
Preferably, being provided with upper vertical axle sleeve in the top of stand column pile, stand column pile bottom is provided with lower vertical axle sleeve, described perpendicular
