Shanghai Huahong HongliFABThe first phase of the supporting project is located in Zhangjiang High-tech Park, Pudong New Area, Shanghai.，East to Halley Road，West to Jinke Center，South to Changtai Square，North to Guo Shoujing Road，The total land area of the project is 91896..16m2。The proposed project mainly constructs 3 dormitories.、1 workshop and 2 R & D buildings，The lower part is provided with an underground garage，And that underground of each single body is communicate with the outward expansion basement.。After the completion of the project，While greatly improving the living environment of Huahong Grace employees,，New construction of finished product test room，It will further enhance the operational efficiency and competitiveness of Huahong Hongli.。

▲Location of the project

The pile foundation of this project is constructed by the method of static drilling and embedment.，The total quantity of embedded piles is 1298.，About 4.20,000 meters，Pile length 29-36m。Pile type shall be selected：PHC 500(100) AB C80+PHDC 550-400(95) AB-500/400 C80，Borehole diameter：650mm，Bore diameter：975mm，Bottom expansion height：2000mm。

▲Project plan

The site is adjacent to existing roads and buildings, and there are pipelines around the site.，Complicated environmental conditions，Possible deformation to foundation construction、More sensitive to vibration, etc.，Extremely high requirements for soil compaction in pile foundation construction，In close proximity to the building，Difficult working condition of on-site construction mud treatment，How to complete the project within 40 days，It has also become one of the difficulties in the pile foundation construction of the project.。

▲Project site

It is a green environmental protection pile foundation construction equipment independently developed by Shanggong Machinery.，SDP220HWith excellent product performance, the static drilling and rooting machine has become the first choice of the project side.。This product not only has a large torque,，The drilling depth is large，The reliability is good，And that construction efficiency is high，But also has that advantage of small vibration during construction,、Low noise、Energy saving and emission reduction, etc.。

▲SDP220HDuring the construction operation of the static drilling and rooting machineThere is speed、There is depth、Precision is right.SDP220HThe Best Interpretation of Static Drilling Rooting Machine，Two sets of equipment on site are used to form about 300 piles in a single daym，About 10-Construction efficiency of 12 piles，Ensure stable and efficient construction progress。

▲SDP220HDuring the construction operation of the static drilling and rooting machine

Excellent product，The market is never stingy with praise.。On-site operator feedback：“As an old handheld player for many years.，Shanggong MachinerySDP220HThe equipment torque of the static drilling rooting method machine is large、Power is strong、Drilling and underreaming are very efficient，The whole machine works reliably and stably.，It is an effective guarantee for project construction.。”

Future，Shanggong Machinery will continue to stand in the perspective of customers、Market perspective，Focus on creating differentiated core competitive advantages and products，Creatively meet customers' realistic and value needs，Lead the development of underground foundation construction industry。

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.。
