【摘要】：本文旨在研发一种性能优异、施工快捷、能循环利用的钻井工程附属设备基础,并实现其工厂化和模块化施工。装配式设备基础属于一种新型组合基础,并没有统一的计算方法与设计规范,要想推广装配式设备基础在钻前工程中使用,必须要保证结构在设计中所需要的延性,足够的强度、刚度以及抗冲切能力,使预制基础具备足够的变形能力以及充足的安全储备,严格控制装配式基础预制构件破坏时的裂缝宽度以及装配式基础预制构件的不均匀沉降,保证地基、装配式基础以及设备直接的协同工作及其整体稳定性。具体研究内容如下:1)预制基础的模块化设计:根据不同地质情况,钻井工程的常见规模和附属设备的自重、形状、尺寸等参数,设计出相应的混凝土预制基础并实现其模块化,包括预制基础的形状、尺寸、配筋、预埋件的留设、预制基础的吊装、承载力和抵抗变形能力;2)地基、设备和基础的整体稳定性研究:地基与基础的锚固,地基与基础的锚固方式拟采用螺杆锚筋锚固,需要研究锚杆的直径、长度、锚固方法和锚固后基础的稳定性;基础与设备的连接,钻井工程附属设备种类较多,尺寸、形状各异,需要研究基础与不同设备的细部构造连接问题,包括孔洞的留设、连接件的构造、形式和具体布置等;3)研发相应的完整的技术可行、经济合理的施工工艺流程,并进行经济技术分析。本文对此研发设计出了2种适用于钻前工程附属设备的装配式基础,实现其模数化、标准化、规模化生产技术和标准化拼装技术,并对其进行了相应的理论分析,保证装配式构件的合理拼装、预制构件的安全设计以及装配式基础与地基的稳定性连接,绘制出相应的施工图集,研制出相应可行的施工工艺流程,并对整套装配式基础方案进行了经济技术分析。
[Abstract]:The purpose of this paper is to develop a kind of auxiliary equipment foundation of drilling engineering, which has excellent performance, fast construction, and can be recycled, and realize its industrial and modular construction. The assembly equipment foundation belongs to a new type of combination foundation. There is no uniform calculation method and design specification. In order to promote the use of assembly equipment foundation in pre-drilling engineering, it is necessary to ensure the ductility, strength, stiffness and punching ability of the structure needed in the design. Make the prefabricated foundation have enough deformation ability and sufficient safety reserve, strictly control the crack width of the prefabricated component and the uneven settlement of the prefabricated component of the prefabricated foundation, so as to ensure the foundation, The modular design of prefabricated foundation: according to different geological conditions, the common scale of drilling engineering and the weight and shape of auxiliary equipment, Design and modularize the corresponding precast concrete foundation, including the shape, size, reinforcement, embedded parts, hoisting, bearing capacity and resistance to deformation of the prefabricated foundation, and other parameters, including the shape, size, reinforcement of the prefabricated foundation, the hoisting of the prefabricated foundation, the bearing capacity and the ability to resist deformation. Research on the overall stability of equipment and foundation: the Anchorage of foundation and foundation, the anchoring mode of foundation and foundation is to adopt screw anchor bar, it is necessary to study the diameter, length, anchoring method and stability of foundation after anchoring. The connection between the foundation and the equipment, the drilling engineering accessory equipment kind is many, the size, the shape is different, need to study the foundation and the different equipment detail construction connection question, including the hole retention, the connection member construction, In this paper, two kinds of prefabricated foundation suitable for pre-drilling engineering are designed and designed, and the corresponding complete technical feasible, economical and reasonable construction process flow is developed, and the economic and technical analysis is also carried out. The modular, standardized, large-scale production technology and standardized assembly technology are realized, and the corresponding theoretical analysis is carried out to ensure the reasonable assembly of assembly components. The safety design of prefabricated components and the stability connection between the prefabricated foundation and the foundation are obtained, the corresponding construction maps are drawn, the corresponding feasible construction process is developed, and the economic and technical analysis of the whole assembly foundation scheme is carried out.
