摘   要:干硬性混凝土主要用于水利、机场道面及公路工程中,对振捣质量要求较高,但传统振捣工艺依赖人工经验,存在主观性与滞后性,难以保证振捣质量,易引发结构缺陷。因此,一系列以悉知、分析和控制为主的混凝土智能化振捣技术应运而生。本文首先阐述了干硬性混凝土的材料特性与工程应用特点,并分析了其振捣机理;随后,在调研与梳理混凝土振捣密实度表征指标的基础上,系统分析了智能化监控技术与机器人自动化系统在混凝土振捣智能化中的应用现状;最后;总结了干硬性混凝土智能振捣研究中出现的问题,并展望了智能振捣技术的未来发展方向。综述成果可为干硬性混凝土振捣技术的智能化发展提供借鉴。Abstract: Dry concrete is mainly used in water conservancy projects, airport pavements, and highway engineering, and has high requirements for vibration quality. However, traditional vibration technology relies on manual experience, leading to subjectivity and lag. It is difficult to ensure vibration quality, which is prone to causing structural defects. Therefore, a series of intelligent vibration technologies for concrete, focusing on perception, analysis and control, have emerged. First, this paper expounds the material properties and engineering application characteristics of dry concrete and analyzes its vibration mechanism. Then, on the basis of investigating and sorting out the characterization indicators of concrete compaction degree, the application status of intelligent monitoring technology and robotic automation systems in the intelligent vibration of concrete is systematically analyzed. Finally, the existing problems in research on the intelligent vibration of dry concrete are summarized, and the future development direction of intelligent vibration technology is prospected. The review results can provide a reference for the intelligent development of dry concrete vibration technology.

摘   要:通过湿度监测、力学性能测试、压汞测试与X射线断层扫描分析,研究了3D打印混凝土不同高度处的相对湿度对力学性能、微观结构的影响。结果表明:构件内部沿竖直方向的相对湿度从中间向上下两端逐渐增加;靠近上下两端处试件的抗压强度、劈裂抗拉强度较低,而中间处试件的抗压强度、劈裂抗拉强度较高;与中间处样品相比,靠近上下两端处样品的总孔隙率较高,大孔占比较多,内部存在明显缺陷。Abstract: The influence of relative humidity at different heights on the mechanical properties and microstructure of 3D printed concrete was studied through humidity monitoring, mechanical properties testing, mercury intrusion testing, and X-ray tomography analysis. The results indicate that the relative humidity inside the component increases gradually from the middle to the upper and lower ends along the vertical direction. The compressive strength and splitting tensile strength of the specimens near the upper and lower ends are lower, while the compressive strength and splitting tensile strength of the specimens in the middle are higher. Compared with the sample in the middle, the sample near the upper and lower ends has a higher total porosity, with a larger proportion of large pores and obvious internal defects.

摘   要:预应力钢筒混凝土管(Prestressed concrete cylinder pipe,PCCP)作为重要的输调水管材,具有高强度、高耐久性能的优势,但其传统管理模式普遍存在效率低、信息孤岛、安全隐患等问题。为此,本文综合现有管道相关的智能建造技术,分析了其技术优势,探讨了其在PCCP全生命周期中应用的可行性。在PCCP设计与生产制造阶段,BIM与VR技术可实现设计优化,自动化生产线和工业机器人可提升工艺精度,物联网技术可保障全程监控;在运输和施工阶段,5G+北斗系统可优化物流路径,智能施工设备可确保安装质量;在运维管理阶段,可通过光纤传感、激光雷达、智能巡检机器人等技术构建实时监测预警体系。智能建造技术的应用不仅能显著提升PCCP工程质量和安全水平、降低全周期成本,而且能增强PCCP在复杂环境下的适应能力,从而为 PCCP 行业向数字化、精细化、可持续化方向发展提供技术支撑。Abstract: As a critical type of pipeline for water transmission and diversion projects, prestressed concrete cylinder pipe (PCCP) has advantages including high strength and excellent durability. However, its conventional management paradigm generally suffers from issues such as low efficiency, information silos, and potential safety hazards. In response, this paper synthesizes existing intelligent construction technologies related to pipelines, analyzes their technical merits, and explores the feasibility of their application throughout the entire life cycle of PCCP. In the design and manufacturing stage of PCCP, BIM and VR technologies enable design optimization, automated production lines and industrial robots improve process precision, and the internet of things ensures full-process monitoring. In the transportation and construction stage, the 5G+BeiDou system optimizes logistics routes, and intelligent construction equipment guarantees installation quality. In the operation and maintenance management stage, real-time monitoring and early warning systems can be established using technologies such as optical fiber sensing, light detection and ranging, and intelligent inspection robots. The application of intelligent construction technologies can not only significantly enhance the engineering quality and safety level of PCCP projects and reduce life-cycle costs, but also strengthen the adaptability of PCCP in complex environments, thereby providing technical support for the digital, refined, and sustainable development of the PCCP industry.

摘   要:以某混凝土3D打印空间双曲型市政建筑项目为依托,阐述了复杂双曲型市政建筑的3D打印设计方法、材料优化、打印工艺及建造技术,通过参数化衍生设计构建柱子屋面一体化拱形结构体系,采用NURBS曲面重构算法实现了围护结构三向节点的自适应切分,提出了动态法平面迭代细分策略,解决了异形构件打印路径规划难题。采用 3D打印纤维增强混凝土,通过非均匀层积工艺控制三向节点打印精度,结合堆砂支撑完成了大悬挑屋盖的打印。建立了混凝土3D打印结构-钢结构协同安装体系,打印-浇筑复合增强结构使屋面承载力提升近100%。工程实践表明,基于混凝土3D打印技术的分层递进式施工工艺,可实现双曲型建筑结构的精准成型与高效装配。Abstract: Taking a concrete 3D printed spatial hyperbolic municipal structures project as the research object, the 3D printed design methodology, material optimization, printing techniques, and construction technologies of 3D printing for complex hyperbolic municipal structures were elaborated. Through parametric generative design, an integrated column-roof arch structural system was established. NURBS surface reconstruction algorithms were employed to achieve adaptive segmentation of ternary branching structure, and a dynamic normal-plane iterative subdivision strategy was proposed to resolve path planning challenges for non-uniform component printing. The printing of large cantilevered roof was completed by using 3D printing of fiber-reinforced concrete, controlling the printing accuracy of ternary branching structures through non-uniform layering technology, and combining with sand pile supports. A collaborative installation system integrating concrete 3D printing and steel structures was established, where the roof load-bearing capacity increased by nearly 100% by composite-enhanced printed-cast components. Engineering practice demonstrates that the hierarchical progressive construction process based on concrete 3D printing enables precise forming and efficient assembly of hyperbolic structures.
