AI Technical Summary

Technical Problem

In the case of uneven bottom of the drill hole, the hardened medium is prone to seep into the pile pipe, resulting in a decrease in the load-bearing capacity of the foundation pile and low filling efficiency, and the inability to effectively control the filling of the medium.

Method used

Pile pipes with partitions are designed. The partitions divide the internal space into lower sections and upper sections. The isolation and connection of the two sections are controlled through a closure device to prevent media penetration, and the medium is supplied with sealing elements and pipelines to ensure that Fill control.

Benefits of technology

Effectively prevent hardened media from penetrateing into the pile pipe, reduce media consumption, ensure the load-bearing capacity of foundation piles, and achieve controllable filling and diversified use.

Abstract

The invention relates to a pile tube (10) for forming a foundation pile in the soil, comprising a tubular base body (12),-wherein a partition (20) is arranged in an inner region (13) of the tubular base body (12), which partition divides the inner region (13) into a lower section (14) and an upper section (15) and separates them from one another,-wherein at least one passage opening (22) with a closure device (24) is arranged on the partition (20), the through-opening (22) can be closed and opened by means of the closure device, and wherein at least one supply opening (32) for supplying a hardenable medium is arranged on the partition (20), characterized in that at least one line (26) extends from the at least one supply opening (32) along the lower section (14) of the tubular base body (12), the at least one line (26) extends through the tube wall (16) of the tubular base body (12) and opens into the outlet opening (28), by means of which the through opening can be closed and opened.
