To address the issues of low efficiency, significant environmental disturbance, and difficulties in attitude control in shaft construction in urban areas with dense buildings and limited space, this study proposes an innovative vertical mechanized construction technology centered on a cutting-type shaft boring machine, prefabricated segment structures, and a sinking construction method for isolated-boulder-bearing strata and high-strength rock strata. The effectiveness of this technology has been verified through its practical application in the No. 2 shaft project on the Jingxi Road-Baiyun Dongping section of the Guangzhou-Huadu intercity railway. The engineering practice results indicate that the adoption of undrained excavation with cutting bits and prefabricated assembly technology inside the shaft has significantly reduced the construction difficulty of the retaining structure, minimized stratum disturbance, and improved construction efficiency. The advance shaft advance excavation mode can effectively reduce stratum settlement and shear stress. The alternate excavation mode is suitable for strata with good mechanical properties, while the synchronous excavation mode is applicable to general strata (including those containing boulders), which can effectively control stratum settlement and deformation. Through the optimized design of drum picks, the drum grille and the slurry circulation system, the modified shaft equipment demonstrates stronger adaptability under complex geological conditions such as boulder-bearing strata and high-strength rock formations. The research results can provide a reference for the optimization of shaft equipment and construction technology in similar soft-hard alternating granite composite strata.

为解决空间狭小区域竖井施工中面临的效率低、环境扰动大、姿态控制困难及城区建筑密集等问题,针对含孤石的地层及高强度岩层,提出一种以截削式竖井掘进机、装配式管片结构及下沉式施工方法为核心的垂直机械化施工技术,并通过广花城际京溪路至白云东平区间2号竖井工程的实际应用验证其有效性。研究结果表明:采用截削式刀头井内不排水开挖与预制拼装工艺,显著降低围护结构施工难度,减少地层扰动,提升施工效率;竖井掘进超前模式施工能够有效减少地层沉降和剪应力,交替掘进模式适用于力学性能良好的地层,同步掘进模式适用于一般地层(包括含孤石的地层),可有效抑制地层沉降与变形;结合滚筒截齿、滚筒格栅及环流系统的优化设计,改造后的竖井装备在含孤石地层和高强度岩层等复杂地质条件下表现出更强的适应性。研究成果可为类似软硬交替花岗岩复合地层的竖井装备优化与施工工艺提供参考。

为解决空间狭小区域竖井施工中面临的效率低、环境扰动大、姿态控制困难及城区建筑密集等问题,针对含孤石的地层及高强度岩层,提出一种以截削式竖井掘进机、装配式管片结构及下沉式施工方法为核心的垂直机械化施工技术,并通过广花城际京溪路至白云东平区间2号竖井工程的实际应用验证其有效性。研究结果表明:采用截削式刀头井内不排水开挖与预制拼装工艺,显著降低围护结构施工难度,减少地层扰动,提升施工效率;竖井掘进超前模式施工能够有效减少地层沉降和剪应力,交替掘进模式适用于力学性能良好的地层,同步掘进模式适用于一般地层(包括含孤石的地层),可有效抑制地层沉降与变形;结合滚筒截齿、滚筒格栅及环流系统的优化设计,改造后的竖井装备在含孤石地层和高强度岩层等复杂地质条件下表现出更强的适应性。研究成果可为类似软硬交替花岗岩复合地层的竖井装备优化与施工工艺提供参考。

To address the issues of low efficiency, significant environmental disturbance, and difficulties in attitude control in shaft construction in urban areas with dense buildings and limited space, this study proposes an innovative vertical mechanized construction technology centered on a cutting-type shaft boring machine, prefabricated segment structures, and a sinking construction method for isolated-boulder-bearing strata and high-strength rock strata. The effectiveness of this technology has been verified through its practical application in the No. 2 shaft project on the Jingxi Road-Baiyun Dongping section of the Guangzhou-Huadu intercity railway. The engineering practice results indicate that the adoption of undrained excavation with cutting bits and prefabricated assembly technology inside the shaft has significantly reduced the construction difficulty of the retaining structure, minimized stratum disturbance, and improved construction efficiency. The advance shaft advance excavation mode can effectively reduce stratum settlement and shear stress. The alternate excavation mode is suitable for strata with good mechanical properties, while the synchronous excavation mode is applicable to general strata (including those containing boulders), which can effectively control stratum settlement and deformation. Through the optimized design of drum picks, the drum grille and the slurry circulation system, the modified shaft equipment demonstrates stronger adaptability under complex geological conditions such as boulder-bearing strata and high-strength rock formations. The research results can provide a reference for the optimization of shaft equipment and construction technology in similar soft-hard alternating granite composite strata.
