Abstract

The invention provides a prefabricated pile foundation structure and an intelligent auxiliary construction method, comprising: a prefabricated column, a covering layer and a rock layer, the top surface of the rock layer is covered with a covering layer, and a linkage expansion positioning device is buried inside the rock layer. The sedimentary block, the central position of the sedimentary block is interspersed with a prefabricated column, the top surface of the sedimentary block is located outside the prefabricated column, and a balance block that can be docked and fastened is set, and the surface of the rock layer is symmetrically placed on the side of the sedimentary block There are four upright blocks, and the surface of the upright block is fixed with a double fastening, fixed connection and fastening mechanism. The present invention uses it as the positioning foundation of the pile foundation, effectively solving the problem that the existing pile foundation uses a long degree of freedom to ensure stable positioning. It is more suitable for the fixing of pile foundations in the shallow area of ​​the covering layer. At the same time, the degree of freedom of the prefabricated column is increased through the balance block upwards, and the opposite pulling force is formed with the alignment block and the fastening mechanism. Greatly improve the side support stabilization effect on prefabricated columns.

Description

technical field [0001] The invention relates to the technical field of hydraulic pile foundations, in particular to a prefabricated pile foundation structure and an intelligent auxiliary construction method. Background technique [0002] Pile foundation structure is one of the important forms of foundation structure in water transport engineering, and it is widely used in wharf structures. Because there will be many safety problems if cast-in-place piles are used in wharf, only prefabricated piles can be used. For the pile foundation bearing horizontal force or moment, its penetration depth must meet the conditions of elastic long piles, that is, for the pile foundation bearing horizontal force or moment, its penetration depth must meet a certain embedded depth requirement. In the area where the overburden is shallow, it is difficult for the prefabricated piles to sink to the design requirements. At this time, it is necessary to consider the necessary stabilization measures ...
