Drilling With Mechanical Conveying TRIZ Cases

Sensors and a computing unit define a safe actuator range in real time, preventing tipping while preserving drilling reach.

Multiple drill-shank outlets switch during sinking and retraction to mix soil with fluid more uniformly and form homogeneous soil mortar.

A flexible cover on an independent mast carriage contains soil and suspension thrown by rotating cultivation tools.

This case combines one-way fluid control with torque transfer, helping a downhole bailer retain debris during retrieval.

This case shows how a ball check mechanism enables torque transfer to the milling bit while retaining debris during retrieval.

A modular rotating table with interchangeable accessories adapts excavators to different pile methods.

Segmented outlets on the drill shaft enable selective fluid introduction, resolving mixing quality versus operational flexibility.

A jetting expansion extrusion pile uses a double-frustum expanded body to increase friction resistance area.

In situ freezing via a cooling chamber prevents pore fluid drainage and atmospheric gas replacement, preserving sample integrity.

Hydraulic pivoting units lift the discharge line away from the ground, removing the need for complex crane devices.

An automated facility locates blast-hole cones, extracts undisturbed samples, and processes ore on-site to cut analysis time.
