PROBLEM TO BE SOLVED: To simply recover mud, surely supply a regulated amount to a solidification treatment device, and improve adaptability to a narrowly installing space. SOLUTION: A mud sucking and regulated amount supplying device is so constituted that mud by construction work is sucked and is supplied its regulated amount to a solidification treatment device. This device is provided with a vacuum generator 4, a vacuum tank 1 for setting an internal pressure to a negative pressure by the vacuum generator 4 to suck the mud through a mud sucking hose 7, and as needed, to open to the atmosphere, a hopper 2 installed so as to connect directly under the vacuum tank 1, an opening and shutting means 21 which can be airtightly blocked between the vacuum tank 1 and the hopper 2 at the time of closing, and which can fall the mud stored in the vacuum tank 1 to the hopper 2 at the time of opening, and a displacement typed soil force feed pump 3 by which the mud in the hopper 2 can be fed with pressure. Accordingly, the mud in the hopper 2 can be supplied its regulated amount to a solidification treatment device through a mud supplying hose 8 with the soil force feed pump 3. |
