Pipe Pile Bulkhead Plate for Annular Space Filling Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming foundation piles in uneven boreholes result in excessive penetration of hardenable medium into the pile tube, leading to increased material consumption and impaired load-bearing capacity, as well as uncontrolled transfer of medium into the pile tube, which can cause defects in the surrounding annular space.
Innovation Solution
A pile tube with a bulkhead plate that divides its interior into two sections, allowing for pressure-tight separation and control of medium flow, using a closure device to prevent medium entry into the lower section when filling the annular space with a hardenable medium, ensuring it fills the space outside the tube instead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the borehole bottom is uneven and the hardenable medium is introduced into the annular space, then the foundation pile can be formed, but the hardenable medium increasingly enters the interior of the pile tube from below and fills at least part of the interior, leading to significant increase in material demand
Solution Approach 1:
The interior of the pile tube is divided into a lower section and an upper section by a partition plate. The closure device is arranged on the partition plate to seal the through-opening, preventing the hardenable medium from entering the interior of the pile tube while allowing it to fill the annular space between the pile tube and borehole wall.
2Reliability
If the hardenable medium enters the interior of the pile tube, then material consumption increases, but this uncontrolled transfer leads to defects in the surrounding annular space and impairs the load-bearing capacity of the foundation pile
Solution Approach 1:
The partition plate with closure device is installed in advance within the pile tube before the hardening process. By closing the through-opening beforehand, the system prevents uncontrolled flow of hardenable medium into the interior, ensuring proper filling of the annular space without defects.
3Reliability
If the interior space is filled with hardenable medium, then material consumption increases, but the at least partially filled interior space becomes unavailable for accommodating certain equipment
Solution Approach 1:
The partition plate divides the pile tube interior into lower and upper sections. The closure device on the partition plate prevents hardenable medium from entering the upper section, keeping it available for accommodating equipment while allowing the lower section to remain sealed and structurally sound.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design efficiently and reliably creates foundation piles by minimizing medium consumption, maintaining the interior free for other uses, and enhancing the load-bearing capacity by controlling the hardenable medium's distribution, preventing unwanted entry into the pile tube.
Implementation Method 1
a hardenable medium is introduced into an annular space between a wall of the borehole and an outer circumference of the pile tube
