Introduction

Recently, the "China Machinery Industry Science and Technology Award", jointly established by the China Machinery Industry Federation and the Chinese Mechanical Engineering Society, announced the 2023 review results. XCMG Foundation's "Key Technologies and Industrialization of Super-Large Pile Foundation Construction Equipment for Large-Diameter Deep Piles in Hard Strata" won the first prize of the 2023 China Machinery Industry Science and Technology Award, and "Key Technology R&D and Industrialization of Safe, Intelligent and Rapid Excavation-Anchoring Equipment for Coal Mines" won the second prize.‍

First Prize

Key Technologies and Industrialization of Super-Large Pile Foundation Construction Equipment for Large-Diameter Deep Piles in Hard Strata‍

The project "Key Technologies and Industrialization of Super-Large Pile Foundation Construction Equipment for Large-Diameter Deep Piles in Hard Strata", submitted by XCMG Foundation, successfully stood out from numerous competing projects by virtue of its unique innovative advantages in construction capability under large-diameter, deep-pile and hard-stratum working conditions, efficient construction, safety and intelligence, and modular combined construction, assembly and disassembly.

Based on the key innovative technologies of this project, XCMG Foundation developed a series of super-large-tonnage rotary drilling rigs, meeting the needs of pile foundation construction under complex geological conditions such as large diameter, deep piles and hard strata for large bridges crossing rivers and seas in China. This fundamentally solved the "three highs" problem of long-term reliance on imports for super-large-tonnage rotary drilling rigs, which led to high procurement costs, high maintenance costs and high operating costs, and greatly improved the economic benefits of foundation construction.

The world's largest-tonnage rotary drilling rig XR1600E completed the world's largest pile foundation construction with a diameter of 6.3 m at the Xihoumen Road-Rail Dual-Purpose Sea-Crossing Bridge.

Second Prize

Key Technology R&D and Industrialization of Safe, Intelligent and Rapid Excavation-Anchoring Equipment for Coal Mines‍

Focusing on the challenge of safe and rapid roadway excavation, the project team for "Key Technology R&D and Industrialization of Safe, Intelligent and Rapid Excavation-Anchoring Equipment for Coal Mines" broke through a number of key core technologies, from product functional layout to the R&D of key core components. The rear-mounted intelligent excavation-anchoring machine was successfully developed and industrialized. The project's innovation in key technologies has enhanced the independent design and manufacturing capabilities and competitiveness of domestic excavation-anchoring equipment, promoted the progress of the rapid roadway excavation industry in coal mines, and elevated China's international influence in the field of roadway excavation equipment.

XCMG Foundation has always adhered to innovation-driven development, focusing on national strategic needs, the future development of the industry and the frontiers of innovative science and technology, continuously tackling core key technical challenges. Major technological innovation achievements have emerged one after another, leading the industry to cleave through the waves.
