Introduction of Static Drilling Grounding Method

The static drilling and rooting method is to use the static drilling and rooting pile drilling machine to drill holes.、Whole course mixing and bottom expansion，Finally, the precast pile body is implanted.，Pretensioned prestressed concrete bamboo pile（PHDC）、Pretensioned prestressed concrete pipe pilot（PHC）、Prestressed concrete pipe pile with composite reinforcement（PRHC）Different specifications、Various combinations of models to meet design requirements，And press Drill、Reaming、Grouting、Pile foundation construction method for implantation and other processes。

Characteristics of construction method：

●No soil squeezing，No vibration，Low noise；

●And that pile quality is good，The elevation of pile top is fully controllable.；

●Very strong vertical compression resistance、Withdrawal and horizontal load resistance；

●And that discharge of the slurry is less；

●It has good social benefit and popularization value.。

Scope of application:

●Applicable to various seismic fortification intensity area，Adapt to the pile diameter：500-1200mm；●Cohesive soil、Silt、Sandy soil、Fill soil、Broken（Gravel）Stone, soil and geological conditions are complex.、There are many interlayers、Uneven weathering、Rock strata with large changes in hardness and softness，Maximum buried depth：90m；        When the construction site is adjacent to a building(Structures)Or underground pipelines and other engineering facilities，Use other pile types，When adverse effects will be caused；●The top elevation of pile end bearing layer varies greatly.，When the length of the pile is difficult to determine accurately，The construction site is not available，Conditions for cast-in-place concrete or works in which the quality of cast-in-place concrete is not easily guaranteed；●Works with restrictions on the discharge of large quantities of slurry；●The design requires that the bearing capacity of a single pile is large.，When the technical and economic indicators and construction conditions are superior to those of other pile types.。
