[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.
