Construction method of sinking mattress along water current for river waterway regulation

The invention discloses a construction method of sinking a mattress along water current for river waterway regulation, which comprises the steps of mapping underground in a mattress-sinking region, drawing up the trajectory of sinking the mattress along the water current, positioning a mattress-sinking ship, fabricating a soft mattress, sinking the mattress and the like, thereby creating the beginning of mattress-sinking construction along the water current for the bottom protection-based concrete block soft mattress; in addition, the construction method can carry out accurate and effective control on a geotextiles-laying vessel and ensure the construction safety and the construction quality by reasonably setting a ship anchor of the geotextiles-laying vessel; additionally, the construction method can also powerfully protect the construction quality by carrying out precise positioning on a mattress head and a mattress tail of the soft mattress, carrying out real-time tracking on the geotextiles-laying vessel,
