These “new construction methods and equipment technologies” of SEMW appeared at the 11th Deep Foundation Engineering Development Forum

From October 18th to 20th, affected by the epidemic, the twice-postponed 11th Deep Foundation Engineering Development Forum and 2021 Deep Foundation Engineering Technology and Equipment Fair were successfully held in the Galaxy Hotel Taiyuan. As one of the special co-organizers, SEMW gave a special report on key technologies such as TRD construction method and construction equipment, CSM construction method and construction equipment, and MJS construction method and equipment with the theme of "Introduction to Construction Method and Equipment of Equal Thickness Cement-soil Mixing Wall".

The Deep Foundation Engineering Development Forum is co-sponsored by the Deep Foundation and Underground Space Engineering Branch of the China Construction Industry Association, the Pile Machinery Branch of the China Construction Machinery Society, the Pile Engineering Branch of the China Construction Machinery Society, and the Soil Mechanics and Geotechnical Engineering Branch of the China Civil Engineering Society. The theme of this forum is "Industrial Linkage Builds a Solid Foundation", and well-known experts and scholars in the field of deep basic engineering are invited to give industry development reports, conference reports, and parallel forum special reports. After ten years of continuous exchanges, the forum has formed distinctive features of focusing on the development situation, closely following the needs of the industry, integrating resource cooperation, and promoting technical exchanges. It has become the industry's frontier of exchanges, resource platform, and cooperation highland.

At the meeting, Huang Hui, deputy general manager of SEMW, gave a special report on "Introduction to Construction Method and Equipment of Equal Thickness Cement-soil Mixing Wall".

TRD construction method and construction equipment: The report describes the TRD construction method construction principle, TRD construction method construction technology, TRD construction method wall method, TRD equipment shutdown maintenance requirements, TRD construction method advantages, TRD construction method application fields, etc., SEMW independently in 2012 Successfully developed the first TRD equipment with a construction capacity of 61m in China. At present, three major series of TRD-60/70/80 (dual power system) have been formed. Among them, the TRD-80E (pure electric power drive) construction method machine has created a world record with a maximum construction depth of 86m. , Has become the leading enterprise of TRD construction machinery in the industry. Mr. Huang enumerated a number of typical construction cases from all over the country, deeply analyzed the main technical features, new technologies, and new intelligent control technologies of the three major series of TRD construction machines of Shanggong Machinery, and comprehensively introduced TRD construction equipment in the construction of cement mixing walls of equal thickness. Core strengths in the field;

CSM construction method and construction equipment: CSM construction method is also called milling deep mixing construction method. The report combines the construction technology and advantages of CSM construction method, and focuses on sharing that the SEMW MS45 double-wheel agitator drilling rig product adopts direct drive of variable frequency speed motor, instead of hydraulic transmission system, and forced motor cooling. Technology and other aspects of technological innovation, as well as product construction management system technology adopts a number of data collection and storage technologies, detection systems, monitoring systems, monitoring systems, fault diagnosis systems and other technologies and technical achievements such as application in multiple typical construction cases.

MJS construction method and equipment: MJS construction method is the omni-directional high-pressure jet construction method. In the report, there was a technical exchange on the cold air treatment in the MJS construction method. Form a modular and serialized construction technology, covering a variety of strata and construction conditions. From pulping, spraying, to subsequent discharge and mud water treatment, the construction chain is formed. Auxiliary flow and pressure data acquisition module realizes the controllable construction process, and its advantages in the construction field of uniform thickness cement mixing wall are fully demonstrated.

Finally, Mr. Huang mentioned that SEMW, as a company with equipment manufacturing as its main business, has made great efforts, pioneered and innovated for a century, and has contributed to the development of deep infrastructure projects on a global scale. Today, SEMW has established a support system that fully responds to the requirements of underground engineering equipment for "multi-variety, small batch, heavy engineering, and heavy schemes", and it also provides overall solutions for various types of underground foundation construction.

In the exhibition area of the Deep Foundation Engineering Technology and Equipment Fair, SEMW exhibited the technological innovation achievements of TRD method, CSM method, MJS method and construction equipment, attracting visitors to stop and discuss.
