Inner wall engraving pile and engraving equipment

Abstract

The invention discloses an inner wall knurling pile and knurling equipment, and relates to a building pile, in particular to equipment for knurling an inner wall. A pile body is a hollow body; a circular hole is formed in the center of the pile body in a way of penetrating through the two ends of the pile body. The inner wall knurling pile is characterized in that the inner wall of the circular hole is provided with a spiral knurl; the knurl is of a fixed depth. The equipment of the inner wall knurling pile consists of a machine base, a propelling device and a movable knurling tool, wherein the machine base is arranged at one end of a centrifugal pile; the propelling device is arranged on the machine base; the movable knurling tool is arranged on the propelling device; the movable knurling tool consists of a hollow extension pipe, a movable knurling tool apron, a movable knurling tool and a knurling tool erection device; the hollow extension pipe is fixed on a mounting frame of the propelling device; the movable knurling tool apron is arranged at the top end of the hollow extension pipe; the movable knurling tool is arranged on the movable knurling tool apron; the knurling tool erection device is arranged in the hollow extension pipe, and is connected with the hollow extension pipe. By adopting the inner wall knurling pile and the knurling equipment, the technical problem of difficulty in knurling the inner wall of the pile body is solved.

Description

technical field [0001] The present invention firstly relates to a pile material for construction, and in particular to a concrete pile material which requires internal injection and has a certain resistance. [0002] The invention also relates to an engraving device for large materials, in particular to equipment that needs to be engraved on the inner wall. Background technique [0003] The cross-sectional shapes of precast concrete piles in building foundation engineering mainly include precast concrete pipe piles with circular cross-sections and precast concrete square piles with square or rectangular cross-sections. Since the 1990s, with the standardization of precast concrete pipe piles and the continuous development of production and construction technology, pipe pile products have been widely recognized in foundation engineering, and pipe pile products have their significant advantages in actual engineering, but Insufficient performance in the following areas: [000...
