Abstract: PURPOSE:To make it possible to discharge sludges smoothly in conformity with the quality of excavated subsoil by enabling a fresh water spray nozzle to be slanted and discharging sludges by way of a discharge passage from the position near a curing agent injection part. CONSTITUTION:It is so arranged that fresh water from a water tank 35 be sprayed either to a route in which fresh water be sprayed from a fresh water spray nozzle or a route in which fresh water be sprayed to a sludge discharge route in an outer casing. A pipeline 34 is connected to both pipelines 31 and 32 on a lower pressure side of a high pressure pump 28. By closing a change-over valve 15 installed in the swivel direction of the pipeline 32, the high pressure pump 28 discharges the fresh water sucked up from the fresh water spray nozzle 20 by means of a submersible motor pump 36. Fresh water is reversely sprayed by way of a sludge discharge pipeline 24 by opening a valve 15 so as to eliminate a clogged state produced in a sludge discharge line. In this case, a vacuumer 39 reversely sprays fresh water pumped up from the submersible motor pump 36 to a connection pipeline 27 by the operation of a reverse device. If necessary, the fresh water spray nozzle 20 is slanted to a sludge discharge port so as to discharge the sludges.

Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To create such a new function that has not been seen in the past by providing strain distributions in the well layers of a strained multiple quan tum well structure which is formed by alternately laminating pluralities of well layers having lattice constants which are different from that of a substrate and barrier layers upon another.
