AI Technical Summary

Benefits of technology

This patented testing apparatus has several technical features such as its ability to generate simulated ground damage from various types of drilling operations under laboratory conditions accurately while maintaining their stability over long periods of time. It uses specialized components like rotating mechanism and shuttle rods for precise movement along complex paths without losing precision due to gravity forces. Additionally it includes a vertical calibrator and supporting system where all parts work together smoothly. Overall this technology allows researchers to study how well these devices function properly when they perform certain tasks within realistic environmental scenarios.

Problems solved by technology

This patented describes an improved version of a testing apparatus called Tanker Model Test (TMT). It uses multiple sections or screens instead of just one screen per section but still allows for three dimensions of movement in both directions - vertical stretching and horizontal extension. However, it requires manual labor and can be expensive due to its large sizes.

Abstract

The invention provides a test device for simulating sectional shield excavation. The test device comprises a plurality of unit shield machines which are sequentially connected with one another. Each unit shield machine comprises a driving control unit, two rotary contraction mechanisms and an outer frame, each driving control unit comprises three driving motors, screws of a worm gear are connected to the front end of each driving motor, and wires are connected to the rear end of each driving motor; the three driving motor of each driving control unit respectively equidistantly and fixedly encircle the center of a spindle by the aid of motor fixing components; eight arc-shaped sheets are sequentially connected with one another to form each outer frame, every two adjacent arc-shaped sheets are connected with each other by a fixing sheet, and movable gaps are reserved between every two adjacent arc-shaped sheets; the rotary contraction mechanisms of each unit shield machine are respectively connected to two ends of the corresponding spindle. The test device has the advantages that the rotary contraction amplitudes are controlled by the driving motors and gears, accordingly, rotary contraction is easy to control and is stable, the test device can be contracted and then expanded, and excavation soil loss procedures of shield machines can be completely simulated.
