The family and the country celebrate together，The good news spread again，

On the land of South China，

Go to workDMP-IDigital micro-disturbance mixing pile machine，

Assistance in construction of wharf revetment reinforcement works，Start the first show，

DMPConstruction method enters Guangdong for the first time，

Ushering in breakthrough development，

First oneDMP-IShanggong Green，

On a stretch of coastline.，Especially dazzling。

▲Construction site

The Phase IV Project of Shatian Port Area of Dongguan Port is located on the west coastline of Xidatan, Shatian Town, Dongguan.，The total investment of the project is about 46.300 million yuan，The total length of berth shoreline is 999 meters.，Construction of 100,000-ton container ships for berthing，Designed annual throughput capacity 1.8 million TEUs，It is the largest construction scale ever in Dongguan City.、The special deep-water container terminal with the highest berthing level，It has been incorporated into the national infrastructure interconnection plan for the Guangdong-Hong Kong-Macao Greater Bay Area.。

After the completion of the project，It will further promote the development of Dongguan port logistics and port-vicinity industry.，To provide an important guarantee for the sustainable and healthy development of Dongguan's future coastal economic and industrial belt。

▲Introduction to the project

This projectDMPThe micro-disturbance reinforcement project is constructed by Shanghai Guangda Foundation Engineering Co., Ltd.。The total area of foundation treatment of the project is about 49. 30 thousand ㎡，Foundation treatment zone is divided into 1~9 Nine regions。Among， Area 7 is the reinforcement area for the excavation slope of the wharf revetment，Treatment with four-axis cement mixing pile，The total volume of four-axis mixing piles required for the project is 138273.m³，Number of piles: 3,757、Pile diameterФ850@650、Pile depth 17.6~31.5 meters、The cement content is 18%。

To ensure the construction quality，Improve the uniformity of mixing pile and the quality of pile body，The Owner has considered in many ways，Finally, the upper machinery is used.DMP-IDigital micro-disturbance mixing pile machine equipment，Equipped with digital construction control system，Measures shall be taken to reduce construction disturbance and ground heave.、Cement slurry loss, etc。

▲Construction site

Lift the loading equipment，The project manager said：

The construction working face is formed by backfilling the original fish pond.，The venue is rotten，It is difficult for the pile driver to travel，A large amount of brick slag and steel plate shall be padded.，The construction efficiency is low，The site is close to the Shiziyang Waterway.，The sand layer is rich in water content，Dilution of cement slurry during pile formation。

Work on this one.DMP-IThe performance of the digital micro-disturbance mixing pile machine is far beyond our expectations.，Not only the construction disturbance is small，Operation performance is also excellent.，Stable and efficient，Have the equipment to work，On-site construction is like adding wings to a tiger.！”

Actual combat scene，Shanggong MachineryDMP-IDigital micro-disturbance mixing pile machine relies on intelligent digital construction technology、Small disturbance to the surrounding environment，High pile forming quality and the like.，Good performance。

DMP-IThe digital micro-disturbance mixing pile machine can control the air entrainment pressure and the guniting pressure，At the same time, it is equipped with special-shaped drill rod and differential blade，It can effectively reduce the disturbance to the surrounding soil.；An internal pressure sensor and a verticality sensor are arranged in the drill pipe.，During the construction process, the underground pressure and verticality can be monitored in real time.，Higher pile-forming quality。  

The equipment has an intelligent digital construction control system to make the quality of the construction process controllable.，At the same time, it also greatly improves the convenience of construction.。The contents collected and displayed by the digital construction control system include shotcrete pressure,、Slurry flow、Jet pressure、Underground pressure、Pile depth、Pile forming speed、Pile-forming verticality and other parameters；Can be generated to include pile length、Construction time、Underground pressure、Cement consumption、Construction record of parameters such as pile verticality；At the same time, the construction parameters can be uploaded to the centralized control center，Realize real-time monitoring of the construction process。
