摘要： PURPOSE:To reliably mix two-liquid type hardening chemicals for smoothly performing a chemical grouting operation by forcibly sending the two liquids separately to the vicinity of the injection port formed in the wall of an injection tube, and providing a means for mixing both liquids to contact at right angle in the tube. CONSTITUTION:An injection tube is installed in a given spot. One liquid A of liquid type suspension two-components hardening chemicals G is forcibly sent through the first channel 9, and the other liquid B through the second channel 10. Consequently, a spool valve 6 is pushed down, and so the channel 9 and the first discharge port 11 are communicated with each other, so that the liquid A discharged into a guide chamber 14. With the spool valve 6 positioned at its lower limit. a connecting hole 16 is communicated with a through hole 17, so that the liquid B is discharged into the guide chamber 14 through the second discharge port 12. When flowing down a guide wall 1a, the discharged liquid A contacts at right angle with the liquid B to be discharged, and both liquids are mixed together before being uniformly injected into peripheral ground horizontally from an injection port 4. At this time, the injection tube is rotated or moved axially, according to the necessity.

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 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.

摘要： PURPOSE:To uniformly inject a grout by a method in which a low-pressure grout discharge port is provided on the back of a high-pressure grout discharge port inside an injection tube, and a device to turn and pull up the stream of grout is provided at the basal portion of the injection tube. CONSTITUTION:A high-pressure grout A is sent through an inner tube 10 as a high-pressure grout pathway while turning and pulling up an injection tube 1, and the grout A is injected onto the surrounding ground from a discharge port 12a while pushing down a check valve 13. Then, a low-pressure grout B is discharged from a discharge port 23a through the aperture as a low-pressure grout pathway between the inner tube 10 and the outer tube 20, whereupon the low- pressure grout B flows with the high-pressure grout A and is exactly permeated under pressures into the ground along waterways formed by the high-pressure grout.
