Our company's ultra-large-diameter engineering drill bits have been perfectly applied in key national projects.

2015-06-11

On June 3, 2015, the Z05 main tower pier of the main bridge over the Guyu Gate waterway for the Fuping Railway’s Pingtan Strait Dual-Use Bridge—a key national project—successfully completed the concrete pouring of a 4.5-meter-diameter bored pile. This pile currently represents one of the largest-diameter foundation piles in the history of bridge construction. The drilling bit used for this borehole was custom-designed and manufactured by Luoyang Jiujiu Technology Co., Ltd., featuring an innovative structural design and robust welding techniques, which provided a solid foundation and ensured high-quality results for the smooth completion of Bored Pile No. 4 at the Z05 pier of the Pingtan Strait Dual-Use Cross-Sea Bridge. Additionally, all eight 4.5-meter-diameter drill bits and 20 4.0-meter-diameter drill bits supplied by our company were seamlessly integrated with the corresponding drilling rigs for this critical project.

Technical Review of Slurry Pressure Balance Shield

Abstract: Slurry Pressure Balance Shield (SPB) represents a core type of closed‑face shield machine, which is widely adopted in tunnel engineering projects constructed in strata with high groundwater pressure and high permeability. This paper illustrates the working principle of SPB shields. Two major technical routes are classified according to pressure regulation modes: the direct‑control type (Japanese design) and the indirect air‑cushion control type (German design). A comparison is conducted regarding control logic, pressure stability and stratum adaptability between the two machine types. The excavation‑face stabilization mechanism governed by the coupling effect between filter cake and slurry pressure is analyzed. Technical comparison with Earth Pressure Balance (EPB) shields is also performed, providing references for shield machine type selection and construction‑technology research. 【This article is compiled for popular science purposes in the industry.
