Striving for the “City of the Oriole,” SEMW’s MS series twin-wheel concrete mixers recently proudly assisted in the construction of a key project in Shandong Province’s 14th Five-Year Plan. Overcoming challenges in a foundation pit 150 meters long, 85 meters wide, and 15 meters deep, they created an underground water-stopping curtain. The spectacular sight was truly breathtaking!

The construction of the comprehensive outpatient, emergency, and research building at the Affiliated Hospital of Weifang Medical College is a key project in the province’s 14th Five-Year Plan and a crucial step in further enhancing the hospital’s collaborative development of medical care, education, and research. The project boasts 19 floors above ground and three floors below ground, totaling over 130,000 square meters. Its primary functions include outpatient services, emergency medicine, medical technology, internal medicine wards, research facilities, and a civil air defense hospital. The building will significantly improve the outpatient, emergency, and inpatient environment, expand high-quality medical resources, and provide strong support for the development of a high-quality medical university and the promotion of a healthy Weifang.

Construction in the pit, uneven terrain, cross-construction of equipment, cumbersome coordination and communication, deep foundation pit, inconvenient transportation, unfavorable construction difficulty index: ★★★★

Complex geology, difficult to handle. Thick sand layer, large amount of sticky mud and pebbles easily block the drill bit, making drilling difficult. Difficulty index: ★★★★★

Establish a special technical service team

To ensure the smooth completion of the pre-excavation water-stop curtain project, SEMW Machinery attached great importance to the client’s request and responded proactively. Together with the construction company, Yuanqiang Foundation Engineering (Tianjin) Co., Ltd., they quickly established a dedicated technical service team comprised of process experts, technical backbones, and service engineers.

SEMW Machinery engaged in multiple communications with the construction company regarding product technology, construction techniques, cement ash content, pile quality, and on-site maintenance, and dispatched service engineers to provide on-site assistance throughout the entire process.

Intelligent construction management software support

The equipment, powered by intelligent construction management software, utilizes an intelligent control system that allows preset and monitoring of control parameters for the milling head, hydraulic drill, air compressor, and agitator head inclination. It also collects, monitors, and stores data on verticality and slurry flow, ensuring wall quality.

Thanks to superior product quality, stable equipment performance, and dedicated service, the on-site waterstop curtain project is progressing smoothly.

The project needs to be constructed in a foundation pit with a length of 150m, a width of 85m and a depth of 15m. The total volume of the underground water-stop curtain is 11,000 cubic meters, the depth is 35.5m (the pile bottom elevation is 50 meters below the ground level), the wall thickness is 700mm, and the cement ash content is 30%. Since the construction of the project, the equipment quality is reliable and has always been in full attendance. People never stop the machine, which fully meets the construction needs of efficient attendance. The construction work is carried out at the efficiency of 5 sets of walls in 24 hours. The construction efficiency far exceeds the same-level products in the industry and has been highly praised by the construction party.

Furthermore, the SEMW?Machinery MS series twin-wheel mixing drills utilize a variable-frequency motor direct drive instead of a traditional hydraulic transmission system. This reduces energy consumption by 40% compared to traditional twin-wheel mixing drill transmission systems, significantly reducing operating costs.

The project construction manager praised this, stating, “The construction is efficient and the quality is reliable! This equipment is exactly what the project needs!” The equipment is purely electrically driven, with virtually no vibration or noise. It also offers excellent economic benefits, saving significant fuel costs during continuous daily operation.

To do one’s work well, one must first sharpen his tools. In recent years, SEMW?Machinery has thoroughly implemented its product philosophy of “technological leadership and ingenious manufacturing,” driving high-quality development with innovation, constantly challenging the limits of construction, and bravely scaling the pinnacle of the industry.
