Heavy equipment conveys warmth in winter, and warm foundations build academic dreams | Three “green pile planting machines” from SEMW help expand the college and lay a solid foundation for the future

In the twelfth lunar month, the north wind is biting.

At the construction site of a college renovation and expansion project in Xuhui District, Shanghai.

It was a scene of bustling activity.

Three-stage SEMW  SDP220/264H Static Drilling and Pile Planting Machine

Like three “steel giants”

Standing proudly in the cold wind, it steadily and powerfully turned the drill bit.

This winter, they embody “gentle protection” with their steel-like bodies.

To lay a solid foundation for this land that carries the dreams of students.

Heavy equipment conveys warmth in winter, and warm foundations build academic dreams | Three “green pile planting machines” from SEMW help expand the college and lay a solid foundation for the future!

This project, a renovation and expansion project of a college, is located in Xuhui District, Shanghai. The main construction contents include: a 7-story teaching building, a 4-story cultural and sports complex building, a 12-story student complex building, connecting corridors, and a 1-2 story basement.

According to the site survey, the proposed construction site is surrounded by existing buildings, internal roads, pipelines, etc., making the surrounding environment very complex. Strict noise control is required during construction, and it is essential to avoid any deformation or vibration that equipment may cause to the site and existing buildings. Furthermore, the area 2-3 meters below ground level needs to be cleared (mainly removing obstacles and backfilling with stones and debris), and the limited space, coupled with the large number of construction equipment, makes equipment relocation difficult. The client has extremely stringent requirements for the quality of the piles used in this project.

The new building has a floor area of 61,812 square meters, with a total of 723 root piles used, a total pile length of 23,000 m, a pile length of 25-40 m, a pile diameter of 600 mm, and a base enlargement height of 2,000 mm.

Construction contractor: Shanghai Guanghe Construction Development Co., Ltd.

Pile type selected: Shanghai Zhongchun Gaoke Pile Industry Co., Ltd.

As the main machine type in green and environmentally friendly pile foundation construction, the project uses 3 SDP220H/264H static drilling and rooting machines to undertake the construction of pile foundations for individual buildings.

SEMW’s SDP series static drilling and rooting machine adopts a construction method of drilling, deepening and mixing, expanding the base and precasting the pile body. It is suitable for pile diameters of 500~1200mm and a maximum penetration depth of 80m. The equipment is purely electric driven, environmentally friendly and energy-saving. It features no vibration, low noise, good pile quality, high single pile bearing capacity and low mud discharge, perfectly meeting construction needs.

In practical engineering applications, the SDP series static drilling rigs for pile driving exhibit high torque, strong drilling capability, and a high degree of visualization in process monitoring. While ensuring construction efficiency, they are also greener and more energy-efficient, making them the “performance king” among products in their class. Equipped with intelligent construction management software, they provide real-time monitoring of the construction process to ensure construction quality. Utilizing advanced hydraulic underreaming technology, a single unit can construct approximately 6-8 piles every 12 hours .

Through wind and snow, craftsmanship is honed; deep pile foundations convey profound emotions. With the gentle care of three static drilling and pile-planting machines, a modern campus, embodying hope and dreams, is taking root from blueprints into solid ground. This arduous effort in the winter not only strengthens the building’s foundation but also sows the seeds of perseverance and growth in the hearts of students.

As the “dual carbon” strategic blueprint gradually unfolds, SEMW  is firmly implementing the “technology leadership and craftsmanship” strategy to create high-quality products, striving to build a new benchmark in the new energy underground foundation construction equipment industry, and putting into practice the dual carbon vision of “green SEMW, making the world lower carbon”.
