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 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 more securely inject grout in correspondence to the properties of the ground, when injection is shifted from flash setting to slow setting, by shifting injection to slow setting while injecting grout in the period of the shift. CONSTITUTION:A flash setting grout G is injected through an injection pipe 1, and a packer or primary injection is formed around the injection pipe 1. Next, a shifting period grout Gm is injected to complement the flash setting grout G. Then, a slow setting grout Gl is injected to carry out permeation injection. After completion of this injection, the injection pipe 1 is stepped up, and while injection is shifted to a grout of short gel time, step-up is carried out, and in the position the same injection work is repeated.

摘要： PURPOSE:To aim at stabilizing the merging and mixing between carbonated water which is obtained by mixing liquefied carbon dioxide with water and water glass which reacts with the carbonated water, and at making a ground improving device compact by merging the carbonated water with and making the same contact with the water glass while they being injected into the ground. CONSTITUTION:A refrigerator 2 serving as a liquefied condition holding means, a pressure holding valve 4 and a pump 3 are arranged in a supply passage CO2 led from a liquefied carbon dioxide source 1. Then, water is fed from a water tank 6 so as to be merged with and is made into contact with liquefied carbon dioxide so as to obtain carbonated water CW at a first merging point 5. Further, water glass NS is led by a pump 10 from a tank 9 so as to be merged with and made into contact with the carbonated water at a second merging point 8 so as to obtain a grout G which is then injected into the ground through an injection pipe 11 having therein a pressure holding valve 12. With this arrangement, the merging and mixing between the liquids may be stabilized, and the ground improving device may be made to be compact.

摘要： PURPOSE:To balance the feed volume with the supply volume when a material having been blended is press-fed, by providing a supply pump which is mechanically associated with a press-feed pump, between a second grout supply source and a blending section. CONSTITUTION:A press-feed pump 6B for a blended material (carbonated water) and a supply pump 6A for water, which are disposed in a reaction tower 3 in which a first grout 2 (CO2) and a second grout 4 (water) are mixed, are mechanically associated with each other with the press-feed volume of the pump 6B and the supply volume of the pump 6A being set so as to have a predetermined ratio therebetween. Further, thus obtained carbonated water is mixed with water glass NS press-fed by a pump 6C in an injection pipe 1, and thus obtained mixture is injected into the ground. With this arrangement, it is possible to hold the concentration of the carbonated water during a certain time elapse.
