Horizontal qualitative crossing mud recovery system is the equipment for horizontal directional crossing construction, and it is the mud recovery system which is more used in non-excavation drilling nowadays, during the process of engineering drilling, the mud recovery system separates the excavated soil from the mud base liquid, and the mud treated by the horizontal directional crossing mud recovery system can be recycled, which effectively reduces the amount of mud and saves the construction cost to a great extent. The recycled mud is a "mature mud" with stable performance, which can also reduce underground accidents due to unstable performance and ensure the smooth implementation of the traversing project.
