Guiding mechanism of pile foundations for construction

Abstract

The invention belongs to the technical field of pile foundations, and discloses a guiding mechanism of the pile foundations for construction. The guiding mechanism of the pile foundations for the construction comprises a base plate, wherein a placing cavity is formed in the base plate, the upper end and the lower end of the placing cavity are provided with open structures, a plurality of guiding cylinders distributed in a matrix are connected in the placing cavity through a plurality of connection plates, an extension cylinder is detachably connected with the upper end face of each guiding cylinder, two connection ribs symmetrically distributed are fixedly connected with the outer wall of each guiding cylinder, and an insertion groove is formed in one side, far away from the base plate, ofeach connection rib. Users can set intervals of the guiding cylinders according to the actual distribution and size of the project pile foundations, and fixing of the guiding cylinders is completed through locking blocks, and therefore by adopting the mode, the guiding mechanism of the pile foundations for the construction can adapt to positioning and guiding of multiple types of the pile foundations, enlarges the application range, can be dismounted into multiple single components for transportation after the construction is completed, can install the extension cylinders according to needs,and improves guiding stability, thereby improving practicability of the mechanism.

Description

technical field [0001] The invention belongs to the technical field of pile foundations, in particular to a pile foundation guiding mechanism for construction. Background technique [0002] Pile foundation is a foundation form with high bearing capacity, wide application range and long history. With the improvement of production level and the development of science and technology, the type, technology, design theory, calculation method and application range of pile foundation have been greatly developed, and are widely used in high-rise buildings, ports, bridges and other projects. The foundation is a deep foundation that connects the tops of several piles into a whole through caps to bear dynamic and static loads together. The piles are vertical or inclined foundation components set in the soil, and their function is to pass through the weak high compressibility. The soil layer or water transfers the load borne by the pile to the harder, denser or less compressible foundat...

Problems solved by technology

[0003] In the prior art, when driving piles, the guide and positioning mechanism will be used to limit the piles, so that the piles can be driven into the designated positions according to the specified trajectory. Since the pile foundation is composed of multiple root piles and caps, the distribution distance of the root piles at this time The position of the bearing platform needs to be limited, and the existing guide mechanism is divided into two types, one is the single pile positioning type, when using this method for piling, it is necessary to constantly change the position and re-calibrate the installation, which is more troublesome. One is the multi-pile integrated type, and although the multi-pile integrated type does not require repeated calibration, it is only used for pile foundations of a single type and specification, which reduces the applicability
