摘要： PURPOSE:To exactly stabilize a heterogenous ground by a method in which a two-component grout is separately sent under pressure into a double injection tube, jointedly mixed together in a mixing injection chamber, and jetted into the ground. CONSTITUTION:The liquids A and B of a grout are separately sent under pressure to an injection tube body 1 through the liquid pathways 2a and 3a of an inner tube 2 and an outer tube 3 and then raised gradually. The pressure liquid in a path 6 in a head body 4 connected to the inner tube 2 is injected in a filmy form toward a mixing injection chamber 7 from a jet nozzle 9, and also the pressure liquid in a path 5 is injected toward the mixing injection chamber 7 from a jet nozzle 10, whereupon both the liquids are joined and mixed by collision and then injected just downwardly from a jet nozzle 11.

摘要： PURPOSE:To inject and permeate a grout into the surrounding ground with low speeds under low pressures by using an excavating and injection rod having an outlet and an inlet for a boring liquid at the tip end portion of a small outside diameter, integrated with the tip of the body of a large outside diameter. CONSTITUTION:When water W is supplied through a swivel and inner tube 6, the water W passes through an inside path 7, a communication port 13, an aperture 12, a valve-housing chamber 8, and a groove 14a and is jetted from a jet nozzle 16 to form a hole. When the liquids A and B of a two-component grout material are each sent into the aperture between an inner tube 6 and an outer tube 1, an annular spool valve 9 is pushed down, together with a spring 10, along the valve-housing chamber 8 by the pressure of the liquid B, and the liquids A and B are mixed together in a mixing chamber 8a and discharged into the ground through the aperture. The excavating and injection rod is pulled up, the grout material is injected into the space formed between the rod and the excavated wall, and then the same operations are orderly repeated.

摘要： PURPOSE:To consolidate an injected grout by a projection to secure injection voids by a method in which an injection tube having projections on its periphery is penetrated into the ground, a grout is injected through the inlet of the injection tube under low pressures while pulling up the injection tube by a small extent. CONSTITUTION:A pit 4 is drilled to a given depth under soft ground by using an injection tube 1 having projections 0.5-10mm. in height in places 5-50cm from the tip of the injection tube on its peripheral wall while giving a rotation force and a penetrating force to the tube 1 and also while discharging drilling water W from its jet nozzle 3. From an injection port 5 formed at nearly tip portion of the projections 2, a quick-setting grout S1 is injected to the surrounding ground and the tube 1 is pulled up by 5-50cm. Whereupon, a grout S1 is consolidated by the projections 2 to produce a remarkable packer effect, and an injection void Ho is formed after moving the projections 2. Furthermore, a slow-setting grout L1 is injected at a low pressure of 50kg/cm or less from the injection port 5. These operations are repeated.

摘要： PURPOSE:To bring two pack type chemicals into mutual reaction at an optimum timing and stabilize a heterogeneous ground or the like by a method wherein two elements of chemicals are separately fed under pressure, casued to mix and collide with each other in a mixing-jetting chamber and jetted from the chamber, in the work for the treatment of subsoil water and the improvement of ground. CONSTITUTION:A head main body 4 is connected and fitted to the tip end of a double-structue injection pipe 1 through a screw engagement. The head main body 4 comprises a passage 5 communicated with a chemical feed passage 3a of an outer pipe 3, a passage 6 communicated with a chemical feed passage 2a of an inner pipe 2, and a mixing-jetting chamber 7a which is a recess in the side wall. The material chemicals jetted from both injection nozzles 12, 14 are caused to collide and mix with each other in the mixing-jetting chamber 7a. In this case, the jetting pressure is low, and the chemicals are penetrated and injected into the surroundings while mixing with each other. The peripheral soil is solidified by moving the injection pipe upwards or downwards.

摘要： PURPOSE:To detect an underground buried object in a noncontact manner at a high accuracy by inserting a tube underground which jets a fluid at the tip thereof to detect changes in the pressure of the fluid supplied. CONSTITUTION:A detection tube made up of a double tube forces a drilling liquid W to an internal passage part and a detection liquid W', for example, water to an external passage part. Normally, as the diameter of an injection nozzle 8 is small, a tubular spool 5 is pushed down against an energizing force of a spring 6 by a pressure of the drilling liquid W to excavate the ground by the drilling liquid W with an annular discharge port closed, accomplishing the excavation of a hole. The detection liquid W' is forced continuously or intermittently and jets from a jet port 12 passing a communicating port 10, an annular groove 9 and a passage 11. Any underground buried object X near it will intercept the detection liquid W' causing a rise in the back pressure, which can be detected with a manometer. After the end of the excavation of a hole, a 2-liquid type hardening chemical is fed simultaneously one from a nozzle 8 and the other from a discharge port at a low pressure to be injected into the ground.

摘要： PURPOSE:To exactly prevent the upward effluence of a stabilizing grout by injecting a specific unit amount of a quick-setting grout from the upper injection port into the ground in the stabilizing treatment work of the ground by using a grout. CONSTITUTION:The liquids A and B of a two-component quick-setting grout are sent under pressure through inner tubes 2 and 3 into the first mixing portion 6 of the top device of an injection pipe P. The mixed first liquid G1 is then injected into the ground from the first injection port 7 in an unit amount of 1-6 liters/min, where the mixed grout G1 solidifies without cracks being developed. Then, liquids C and D as grouts suitable for the ground to be improved are sent under pressure through inner tubes 4 and 5 into the second mixing portion 8, and the mixed grout G2 is discharged from the second injection port 9.

摘要： PURPOSE:To simplify the structure of a grout injection system by a method in which each liquid of a two-component curable grout is sent to the first flowpath in an outer tube and the second flowpath with a spool valve in an inner tube, joined in an annular mixing chamber, and then injected into the surrounding ground while being mixed. CONSTITUTION:A first flowpath P1 is formed between outer tubes 22A-22C of a tip device 6 connected to an injection tube body 4 and an inner tube 26, and also a second flowpath P2 is formed in the inner tube 26. When excavating a hole underground, boring is made by jetting a boring water W from a nozzle 10 through a check valve 28, the first flowpath p1, the spool valve 42, and a check valve 36. Also, when improving the ground, the first liquid G1 is sent under pressure to the first flowpath P1 and the second liquid G2 is sent to the second flowpath P2, whereupon the spool valve 42 is pushed down by the second liquid G2 and the liquid G2 is discharged from a discharge port 46 and at the same time a shutter 42B is moved downwards from an injection port 12 to form an annular mixing chamber 48. Then, the first and second liquids G1 and G2 are joined there and mixed, and the mixed liquid is injected from the injection port 12 into the surrounding groud.
