Abstract
In order to grasp the disposal technology of shield waste onsite treatment and the operational effectiveness in Shenzhen, we carry out a questionnaire survey, expert interviews and field investigations on 4 shield waste disposal sites of Shenzhen Metro Lines 6, 12, 13 and 16. We analyze in detail the onsite treatment process, resource-recycling products and process characteristics, summarize and sort out the main problems in the existing onsite treatment process. The results show that the existing onsite treatment process is basically feasible, and the targets of reducing the amount of shield waste, partially recycling and moisture content of mud cake less than 40% have been realized. However, some problems are also found, such as low treatment process efficiency, weak adaptability of treatment equipment, high silt content in recycled sand, and low integration and intelligence of equipment. In order to provide a more economical and feasible treatment scheme for the efficient disposal of shield waste in Shenzhen and other cities of the Guangdong-Hong Kong-Macao Greater Bay Area, some improvement measures and suggestions are put forward from the aspects of equipment performance improvement, treatment process optimization, integration and intellectualization.
