Background

In recent years, subway traffic has gradually become an important infrastructure for solving traffic congestion in cities, and a shield method has been more and more widely applied as a main construction method for subway construction. In urban construction, ground settlement control is the first factor for ensuring the safety of ground buildings, and with the enlargement and perfection of subway traffic networks, subway tunnels inevitably need to pass through more buildings and even operate subway lines under complex geological conditions, which puts higher requirements on the stratum settlement control technology of shield construction.

The ground surface settlement generated in the shield tunneling process is mainly caused by the stratum loss (the stratum loss is the difference between the volume of the excavated soil body and the volume of the built tunnel in the shield construction) caused by the construction. In order to control the stratum loss, the shield machine is provided with a synchronous grouting system, and synchronous mortar is timely injected behind the shield tail to fill the outer gap of the duct piece so as to compensate the stratum loss. The synchronous mortar used in the shield construction process at present adopts a fixed mortar tank, a large amount of mortar is stored in the mortar tank when the shield encounters an emergency or fails and cannot be tunneled, the mortar cannot be used due to long-time non-tunneling, and the mortar can be used only by cleaning and replacing fresh mortar. The existing treatment method is mainly that the slag is directly transported to a wellhead through a slag hopper box and is manually dumped, so that the working efficiency is low, and the cost of manpower and material resources is increased.
