Problems solved by technology
When the steel lattice column of the conventional bored pile is installed, its positioning and guiding structure and construction method are simple, the precision is low, and the construction error is large, which cannot meet the requirements of the prefabricated rectangular pile construction precision control
In the existing technology, in order to carry out precise control of the construction of prefabricated rectangular piles, the existing guiding device must be modified, but the cost of modification is high, it takes a long time, and it cannot have the versatility of multiple sizes, and the scope of application is limited. limit

The invention discloses a precise guiding and positioning device for a prefabricated rectangular pile and a construction method of the precise guiding and positioning device, and belongs to the technical field of constructional engineering. The precise guiding and positioning device comprises a guiding and positioning base, a guiding and positioning frame body fixedly arranged on the guiding and positioning base, a guiding and limiting assembly and two sets of adjusting assemblies; the two sets of adjusting assemblies are arranged at the upper end and the lower end of the guiding and positioning frame body correspondingly; each adjusting assembly comprises two transverse rods and two longitudinal rods, wherein a rectangle is defined by the two transverse rods and the two longitudinal rods; the upper end and the lower end of the guiding and positioning frame body are provided with longitudinal and transverse sliding grooves used for sliding fit of the transverse rods and the longitudinal rods; and the guiding and limiting assembly is used for limiting the rectangular pile, can move in the vertical direction and is connected with the adjusting assemblies. The precise guiding and positioning device is high in positioning control and guiding precision, simple in structure, light, small in occupied site, flexible in use and high in construction efficiency and has universality of various sizes.
Description
technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a precise guiding and positioning device for prefabricated rectangular piles and a construction method thereof. Background technique [0002] As a new type of pile, prefabricated rectangular piles have no corresponding construction experience to refer to, especially the lack of relevant construction positioning control and guiding devices. When the steel lattice columns of conventional bored piles are installed, the positioning and guiding structure and construction method are simple, the precision is low, and the construction error is large, which cannot meet the requirements for the construction precision control of prefabricated rectangular piles. In the existing technology, in order to carry out precise control of the construction of prefabricated rectangular piles, the existing guiding device must be modified, but the cost of modification is high...
