Background

With the continuous development of urban underground engineering, underground diaphragm walls are increasingly applied as common enclosure structures in the process of foundation pit excavation, and particularly in the subway construction industry, as subway construction is mainly concentrated in population-dense areas and novel development areas of large cities, civilized construction requirements of owner units on the localization management of construction sites are very strict. Nowadays, as the trenching machine has the advantages of high trenching efficiency, regular hole shape, wide applicable geological range and the like, the ground connecting wall construction field is commonly used, more slurry is often carried in the construction process, the transfer process on a professional transport vehicle can greatly influence the civilized construction of a site field, and the green construction image of the construction site is seriously damaged. The conventional solution at the present stage is to wash with water, and to wash the spilled slurry back into the diaphragm wall which has just been formed into the grooves, and because of the technical characteristics of diaphragm wall construction, each groove can be washed with water after being dug, so that the problems of high field washing frequency, large washing range and large water consumption are caused. Meanwhile, due to the fact that the water consumption is large, scouring wastewater mostly flows back into the underground diaphragm wall groove directly, the slurry concentration is easy to be over-dilute, and the hole collapse risk is caused. From the aspects of economy, progress and on-site civilized construction, how to reduce the slurry overflow of the trenching machine in the slurry transferring process and achieve the purpose of saving water becomes a technical problem which is urgently needed to be solved for on-site management.
