Abstract

This application relates to a construction device and construction method for ensuring that the pile ends of prefabricated piles enter the bearing layer. The positioning hole passed through, the aperture of the positioning hole is larger than the diameter of the prefabricated pile; the base is provided with a vertical hammering device, and the vertical hammering device is used to hammer the prefabricated pile vertically downward into the bearing layer; the base is also provided with There is an offset correction device, which is used to correct the pile body of the precast pile when the precast pile is offset; there is also a correction control device on the base, and the correction control device is used to correct the prefabricated pile after the precast pile offset is corrected. The position of the pile body is measured. The application has the effect of improving the problem of low implantation efficiency caused by the inclination of the pile body when the prefabricated pile is hammered into the bearing layer.

Description

technical field

[0001] The present application relates to the field of prefabricated pile construction technology, in particular to a device and a construction method for ensuring that the pile ends of prefabricated piles enter the bearing layer. Background technique

[0002] In the design of civil engineering structures, the soil layer that directly bears the foundation load is called the bearing layer when designing the foundation. In the calculation of soil mechanics, the pressure on the bearing layer is continuously reduced, and the pressure can be ignored after reaching a certain depth, and the specific depth can only be known after calculation. The part under pressure is called the bearing layer, and the part below the bearing layer is called the substratum. That is to say, according to the different loads, the bearing layer and the underlying layer are also different. Therefore, when the prefabricated piles are transplanted into the ground, it is necessary to move t...
