摘要： PROBLEM TO BE SOLVED: To provide a civil engineering pipe device capable of smoothly circulating fluid between a pipe body and an inner pipe and facilitating the connection of unit pipes.
SOLUTION: In the vicinity of an interior wall of the pipe body 13, the inner pipe 12 is so mounted that both end sections thereof are respectively connected to communication holes 21A and 21B formed in both end sections of the pipe body 13. When the unit pipes 11 are connected, an exterior wall of the pipe body 13 of one unit pipe 11 is abutted on the interior wall of the pipe body 13 of the other unit pipe 11, a gap 23 extended around the circumference is formed in the abutting section, and the communication holes 21B and 21A are connected to each other through the gap 23.

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 stabilize a heterogenous ground by a method in which the liquids of a two-component grout are separately sent under pressure through a double injection tube, jointed and mixed in a mixing injection chamber in the lower part and also on the side wall of the injection tube, and then injected in a filmy form either in the lateral direction or in just downward direction. CONSTITUTION:The liquids A and B of a grout are separately sent under pressure to a head body 4 through the pathways 2a and 3a of an inner and outer tubes 2 and 3 and then raised gradually. A differential valve 8 fitted into the pathway 6 leading to the inner tube 2 is pushed by pressure liquids and goes down against a spring 9 to block a path 10, the differential vale is stopped, the blocking of jet nozzles 14 and 16 and a path 13 is released and connected with paths 5 and 6, a path 13 is led to the chamber 17, and the liquids from jet nozzles are injected toward the mixing injection chamber 7, jointed and mixed together by collision, and injected diffusively toward the circumferential area. Also, the liquids are injected toward the mixing injection chamber 7a by clearance nozzles 14a and 16a connected to the chamber 20 and path 5, jointed and mixed together there by collision, and injected downwardly in the form of a filmy jet stream.
