摘要： PROBLEM TO BE SOLVED: To solve the problem that pumping energy is exhausted and attenuated by a turbulent flow generated in a bent portion, because a pumped ground hardening material is almost perpendicularly bent at a nozzle portion, on the grounds that a jet nozzle for emitting the jet of ground hardening material by high pressure is conventionally set in a side wall of an injection rod.
SOLUTION: A swirling flow guiding structure 3 is formed in a predetermined portion of a central core channel 12 which communicates with a core nozzle 21 of the injection rod; a plurality of branch channels are provided; and a terminal end of the central core channel is constituted in a swelling curved shape 32. Thus, a pumped material is guided in a swirling manner to the branch channels by splitting a pumped jet flow by curved surface butting, so as to generate the swirling flow causing only a small energy loss.

摘要： PROBLEM TO BE SOLVED: To overcome the following problem of a conventional soil hardener injecting method: conventionally at the time of injection of a hardener, a pair of nozzles are provided for an injection rod such that their injection ports are arranged back to back in order to achieve extension etc. of an arrival distance of a hardener jet, and the discharge pressure and discharge amount from both the nozzles are set to almost the same values; but jetting of the hardener from both the nozzles in the same amount in mutually opposed directions cannot improve an agitation effect by rotation of the rod.
SOLUTION: There is provided a new soil hardener injecting method which is carried out by using the rod having a pair of steppedly overlapping jet nozzles 2, 3 arranged on a side wall at the tip thereof back to back. The nozzles 2, 3 are set so as to discharge the ground hardener in imbalanced quantities, and to improve the agitation effect by achieving a balance between a clear water jet quantity discharged from a clear water jet nozzle 4 arranged at an upper location of the small quantity jet nozzles. In this manner the soil hardener is injected to an expanded injection area in a short time.

摘要： PROBLEM TO BE SOLVED: To solve the following inconvenience: in a soil hardener injecting device, conventionally a lower injection channel is blocked by charging therein a spherical blocking body as a means for switching a mode from downward injection to side injection, but to completely block the channel, an injection nozzle is inevitably arranged at a location over a blocking portion, which disadvantageously causes collision of an injection material against the blocking portion under the nozzle and then feeding of the material to a nozzle hole, resulting in occurrence of turbulence due to agitation.
SOLUTION: There is provided a new soil hardener injecting device, in which a central channel 2 of a rod is divided into a core channel 2a communicating with a core nozzle of a multi-injection nozzle, and a peripheral channel 2b communicating with a lower injection port. Then a blocking body having a channel joint to be fitted into the core channel and a flange for blocking the peripheral channel is dropped to block the peripheral channel communicating with the lower injection port, and in this manner downward injection is switched to side injection.

摘要： PROBLEM TO BE SOLVED: To solve the problem of conventional injection of hardening material wherein the necessary amount of discharge cannot be secured because the hardening agent cannot be placed on injection pressure even if the injection pressure is increased; and wherein increasing water content while reducing viscosity in order to place the hardening material on the injection pressure causes particles of the hardening material to drop and reduces the size of a substantial part and its strength, resulting in the inability to secure a well-balanced, effective amount of discharge.
SOLUTION: A second overlapping injection nozzle 3 is provided on the back of the upper portion of a first overlapping injection nozzle 2 and a third injection nozzle 4 is provided thereon. Cement milk with a water-soluble high polymer added thereto is injected from the core nozzles of the first and second overlapping injection nozzles at a pressure of about 400 kg/cm
2 and in an amount of discharge of about 120 to 130 liters per minute and clean water is injected from the third injection nozzle at the same injection pressure and in an amount of discharge of about 50 liters per minute.
