Positioning and paying-off device for pipe pile construction and construction method

Abstract

The invention discloses a positioning and paying-off device for pipe pile construction and a construction method, and belongs to the field of pipe pile construction. The positioning and paying-off device comprises a lower main rod and an upper main rod, wherein the upper main rod is detachably connected with the lower main rod; a measuring piece is arranged on the upper main rod; the measuring piece is detachably connected with the upper main rod; a pedal disc is mounted on the lower main rod; the outer diameter of the pedal disc is matched with the outer diameter of a pipe pile; the pedal disc sleeves the lower main rod; an elastic supporting piece is mounted below the pedal disc; the elastic supporting piece is suitable for supporting the pedal disc to be positioned on the lower main rod and move up and down along the lower main rod; a side plate is mounted below the pedal disc; the side plate is detachably connected with the pedal disc; and during working, the bottom end of the side plate is suitable for being inserted into the ground. The positioning and paying-off device solves the technical problems that the pipe pile is accurately positioned at a relatively low cost, deviation caused by inclination of the pipe pile is reduced, and later remediation cost is affected.

Description

technical field [0001] The invention belongs to the field of pipe pile construction, and in particular relates to a positioning and setting-out device for pipe pile construction and a construction method. Background technique [0002] In foundation and foundation engineering, there are various forms of foundation treatment, but the design of pipe piles is more common, because pipe piles are convenient for construction and low in cost, especially have absolute advantages in shortening the entire project period, are widely used, and have mature technologies. [0003] In the construction process, the construction quality control of pipe piles is very important, among which the pile position deviation control is also the top priority. Large pile position deviation is also a common quality problem. It is necessary to make up for the construction quality problems by increasing the foundation cap or increasing the number of piles. The project has increased a lot of cost, and the ma...

Problems solved by technology

[0003] During the construction process, the quality control of pipe pile construction is very important, among which the control of pile position deviation is also the top priority, and large pile position deviation is also a common quality problem. Increasing the foundation cap or increasing the number of piles to make up for the construction quality problem has added a lot of cost to the project. The main reason for this is that after the pile driver is in place, the alignment between the center of the pipe pile and the midpoint of the ground pile cannot be controlled. cause large deviation
