Problems solved by technology

[0002] At present, there are not a few shield testing machines that simulate tunnel shield excavation in China, but most of them have single functions, poor versatility, large volume, high manufacturing and testing costs, and it is difficult to widely use them to simulate complex tunnel shield construction. Condition
The specific deficiencies include: (1) The shield testing machine cannot realize the mutual conversion between the balance mode and the mud-water balance mode; (2) The structure design of the cutter head is unreasonable, and the sludge enters the cabin not smoothly; (3) The cutter adapts to the formation Weak capacity, inconvenient maintenance since the knives can only be removed and replaced from the front of the cutter head

Abstract

The invention discloses a dual-mode compound shield testing machine which comprises a shield testing machine, wherein the shield testing machine comprises a shield shell; the front end of the shield shell is provided with a cutter head; the shield shell is internally provided with a soil compartment partitioned by a soil compartment clapboard; the soil compartment is internally provided with a stirring rod along the radial direction; the back surface of the soil compartment clapboard is connected with a grout pipe and a spiral unearthing device; and the spiral unearthing device is communicated with the soil compartment. The grout pipe can be used as a pipeline for muck modifying agents such as foam; and under a balanced mode, the grout pipe can be used as a slurry inlet and outlet pipeline, so that the conversion of working modes of the shield testing machine can be realized easily.

Description

technical field [0001] The invention relates to a shield machine, in particular to a double-mode compound shield test machine which can be used for scientific research or as teaching equipment. Background technique [0002] At present, there are not a few shield testing machines that simulate tunnel shield excavation in China, but most of them have single functions, poor versatility, large volume, high manufacturing and testing costs, and it is difficult to widely use them to simulate complex tunnel shield construction. working conditions. The specific deficiencies include: (1) The shield testing machine cannot realize the mutual conversion between the balance mode and the mud-water balance mode; (2) The structure design of the cutter head is unreasonable, and the sludge enters the cabin not smoothly; (3) The cutter adapts to the formation Weak capacity, inconvenient maintenance since the knives can only be removed and replaced from the front of the cutterhead.
