Abstract

The invention provides a dual-mode shield tunneling machine muck delivery system which comprises a spiral machine muck outlet system. The spiral machine muck outlet system comprises a belt transfer system and a mud-water transfer system, wherein a screw conveyer is connected with a control device, one port of the control device is located at the upper portion of the belt transfer system, and the other port of the control device is connected with the mud-water transfer system. The dual-mode shield tunneling machine muck delivery system has the advantages that the problems of complicated geological tunneling speed, severe device abrasion, long construction period, high construction risk, high input cost and the like of single types of shield tunneling machines are effectively solved; the risk of complicated common shield tunneling modes is reduced; the labor intensity of workers can be reduced; the complicated geology adapting capability of the shield tunneling machine can be improved, the non-normal abrasion degree of the shield tunneling machine can be reduced, and the tunneling speed of the shield tunneling machine can be improved; muck delivery modes can be switched at any time,and the muck delivery efficiency can be improved; the tunneling speed in complicated geological interval is improved, and the construction cost is reduced; the construction safety of the shield tunneling machine in the complicated geological interval is improved.

Description

technical field [0001] The invention relates to tunnel construction, in particular to a dual-mode shield machine muck conveying system. Background technique [0002] With the development of the economy, the advancement of science and technology, and the demand for interconnection, tunnel engineering and rail transit have experienced explosive growth, and the shield tunneling method has been promoted and applied in more and more projects. [0003] Due to the complexity of geology, the selection of shield tunneling methods also faces many problems. Existing shield machines are mainly divided into hard rock tunnel boring machines (TBM), earth pressure balance shield machines, mud-water balance shield machines and some other composite dual-mode shield machines. These existing types are difficult to meet the requirements, especially for some long-distance abrasive sections or water-rich sections. For complex strata, the earth pressure balance shield machine is selected, and the...
