Embodiment 1

[0025] First, the pile is erected on the pile driver; the pile body is adjusted vertically through the adjustment mechanism on the pile driver; the two snap rings of the hoop are clamped on the pile body, so that The guide wheels connected at intervals in the circumferential direction are tightly hugged to the pile body; the front and rear screw rods are connected with the connecting sleeve as a whole, and are symmetrically fixed with a snap ring of the hoop and the pile driver respectively; by rotating the connecting sleeve , change the exposed length of the front and rear screw rods, and precisely adjust the verticality of the pile body; start the pile hammer, drive the pile body vertically into the soil layer along the guide wheel; after the pile sinking, separate the hoop from the pile body, and move the pile driver to The next pile.

[0026] After testing, the verticality of the pile body using the method of the present invention is 0.3% L, where L is the length of the pi...

Abstract

The invention discloses a method for adjusting verticality of a tubular pile sunk by a hammer. The method comprises the following steps of: erecting the pile on a pile driver; adjusting and aligning the verticality of a pile body through an adjustment mechanism of the pile driver; locking a hoop on the pile body to make a guide wheel clasp the pile body; integrally connecting a front lead screw and a back lead screw with a connecting sleeve, and fixing the front lead screw and the back lead screw with the hoop and the pile driver respectively; changing the exposed lengths of the front lead screw and the back lead screw by rotating the connecting sleeve so as to precisely adjust the verticality of the pile body; starting a pile hammer to vertically sink the pile body into a soil layer along the guide wheel; and after the pile sinking is finished, separating the hoop from the pile body and moving the pile driver to a next pile. The method has the advantages of simple structure, convenient operation, and improvement on pile sinking quality and pile sinking progress without changing the original pile sinking machines.

Description

technical field [0001] The invention relates to a method for adjusting the verticality of pipe pile hammering method. Background technique [0002] Because the prestressed pipe pile has a high bearing capacity of a single pile, the bearing capacity of the pile end is 80% to 100% higher than that of the undisturbed soil; the design and selection range is wide; the transportation is convenient, and the pile is fast; the length of the pile is not limited by the construction machinery and can be lengthened arbitrarily ; The pile body is resistant to driving, strong penetrating power, good crack resistance; low cost. It is used more and more in pile foundation design and construction. The hammering pile sinking method has the advantages of simple construction machinery structure, low pile sinking cost, and wide applicability, especially in the construction of pipe pile sinking with complex geological conditions, large hard layer thickness, and large pile diameter. .
