When ride over it is high to control H profile steel top mark on fixed channel steel.Hangs muscle can not be had in the case where fashioned iron does not sink in place.In stake
In the shortest time after machine pile telephone-moving, the H profile steel of scale is sling using pedrail crane, designated position is inserted into, by H-type
It is inserted into design code depth under the self weight of steel, elevation control on positioning channel bar, fixing groove are then hung in by the hangs muscle in H profile steel
Steel rides on the positioning fashioned iron of guide channel two sides laying the soil cement initial set until in hole.
In the present embodiment, it is laid with positioning fashioned iron in the working channel of excavation (guide channel) two sides, is being oriented to by design requirement
The position of bore position and slotting H profile steel is marked on positioning fashioned iron, operator is according to determining position strict control drilling machine pile frame
Movement, it is ensured that drilling axle center in place not partially, while controlling the lower drilling depth of drilling and reaching projected depth, utilizes drilling rod and pile frame phase
To displacement principle, the scale line of drilling depth, the speed and depth bored, promoted under strict control are marked on drilling pipe.Cement stirs
It mixes stake sinking and cement grout should all be injected in lifting process, while strict control is sunk and promotion speed.According to related skill
Art data regulation, subsidence velocity are not more than 0.5m/min, promote speed and are not more than 0.5m/min, suitably persistently stir in stake bottom point
Slip casting is mixed, the original record of each pile is carried out.
In order to guarantee that fashioned iron can reduce the friction with soil cement mixture, by section steel suspended in the soil cement mixture it
Before, anti-friction composition is sprayed on the surface of fashioned iron.
Preferably, using drilling blender in guide channel along the extending direction of guide channel successively drilling, to be formed in guide channel
The multiple soil cement mixtures being sequentially communicated.
In the present embodiment, along the extending direction of guide channel, successively drilling goes out multiple soil cement mixtures to drilling blender, i.e.,
Multiple fender posts are formed, and multiple fender posts are sequentially communicated.
In the present embodiment, optionally, this engineering SMW engineering method stake stake diameter (fender post) is Φ 850mm, pilespacing 600mm, stake
Long 11.5m~8m, interpolation HN700 × 300 × 13 × 24H fashioned iron.Using P.O42.5 grades of ordinary portland cements, cement mixing content
It is 20%.Three axis hollow blade screw mixing drilling machine constructions are selected in SMW engineering method stake.
In the present embodiment, drilling blender drill and promoted overall process in, keep drilling rod uniform rotation, at the uniform velocity under
It bores, is at the uniform velocity promoted, and take high-pressure jet that soil cement is made to stir in hole and mix and stir, mixing-filling must be repeated in stake bottom point,
Guarantee whole stake stirring sufficiently, uniformly, it is ensured that the quality of mixing pile.H profile steel can not repeat to stir when being inserted into ratio more smoothly
Mix a bottom point.If insertion is not smooth when close to stake bottom, can be according to practical stake bottom stratum (sandy silt or silty clay)
Situation repeats mixing pile bottom and divides 1m~3m.
