Drainage Insertion with Vertical Anchor Plate for Slope Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for inserting water discharge pipes in earth slopes are cumbersome, often result in pipe damage from mowing, and fail to ensure proper drainage due to vegetation growth obstructing the pipe ends and reducing discharge capacity.
Innovation Solution
A water course insertion with a vertically extending ground anchor plate and a concave tray design that allows easy placement by excavator, featuring a downwardly extending anchoring plate for secure anchorage within the slope, and flanges to prevent soil and vegetation intrusion, made from high-density polyethene for durability and ease of manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a water discharge pipe end protrudes from the slope in the profile of the water course, then the pipe can discharge water effectively, but the pipe end is vulnerable to damage from mowing bars and vegetation growth
Solution Approach 1:
The insertion divides the pipe end protection into separate functional elements: a tray for positioning, flanges for sealing, and a ground anchor plate for stabilization. This segmentation allows each element to address specific problems independently while working together as a system.
Solution Approach 2:
The insertion acts as an intermediary structure between the pipe end and the slope environment. It mediates the interaction by providing a protective interface that shields the pipe from direct contact with mowing bars and vegetation while maintaining drainage functionality.
2Reliability
If existing insertion methods are used (tray with flange and separate anchorage), then the pipe end is protected, but the placement requires significant time and effort
Solution Approach 1:
The tray, flange, and ground anchor plate are merged into a single integrated insertion component. This combination eliminates the need for separate anchorage operations and reduces the number of installation steps, significantly reducing placement time while maintaining anchorage security.
Solution Approach 2:
The ground anchor plate is pre-formed as part of the insertion structure, with anchorage elements already in position. This preliminary preparation allows for quick installation without requiring separate anchorage steps during the placement process.
3Object-affected harmful factors
If the pipe end is buried deeper in the slope to avoid mowing damage, then protection from mowing is improved, but vegetation growth still obstructs the pipe end and drainage efficiency decreases
Solution Approach 1:
The insertion provides localized protection at the pipe end through the tray and flange structure, while the ground anchor plate extends into the slope to provide stable anchorage. This localized approach protects the pipe end without requiring deep burial that would reduce discharge capacity.

AI summary
Insertion to be placed in an earth slope of a water course said earth slope being part of an earth body, wherein the insertion is tray-shaped for defining a niche in the slope and is provided with a passage for a water discharge pipe extending out of the earth body in order to drain in the water course by means of an end portion accommodated in the niche, wherein the end of the end portion of the water discharge pipe is substantially situated in one plane with the slope or is receded with respect to the slope, characterised in that the insertion is provided with a ground anchor, such as a plate that extends substantially vertically from the lower side of the insertion.
