摘要： PURPOSE: The feed rate of grout materials is appropriately controlled to mix pressurized carbonate water with water glass at a lower pressure than the pressure at which the carbonate water has been prepared to prevent trouble, e.g., the grout flows out of the gas between the feeding pipe and the soil.
CONSTITUTION: High-pressure carbon dioxide is brought into contact with water in a tightly sealed vessel to prepared pressurized carbonated water and the pressurized carbonated water is mixed with water glass in a line mixer under pressurized conditions and the grout is injected into soil for stabilization. At this time, the feed rate of grout materials (pressurized carbonated water and water glass) is appropriately controlled to keep the pressure of the carbonated water in the line mixer lower than that in the sealed vessel.

摘要： PURPOSE:To improve the rise of the strength of a gel body by adding chemicals shortening the gel time of a grout to the silicate grout for stabilizing a ground using alkali silicate as a main agent and carbon dioxide as a curing agent. CONSTITUTION:Alkali silicate having a mol ratio SiO2/M2O (M represents Na, K and Li) of approximately 2-100 and carbon dioxide as a curing agent are mixed inequal capacity, thus forming a silicate grout for stabilizing a ground. When the ground is impregnated with the grout, chemicals such as sulfuric acid, hydrochloric acid, etc., are impregnated. The gel time of alkali silicate is shortened to one sec or less, and the rise of strength in water of a gel body at the initial stage of gelation is increased.

摘要： PURPOSE:To omit a process to install a filling pipe and to secure liquid tightness by constituting a part making contact with a filling port mouth of a flexible material, and by forming the filling pipe in a tapered shape gradually and successively changing from a measurement smaller than the diameter of the filling port to a diameter larger than that from the head end part along the base end side. CONSTITUTION:The outer diametrical measurement on the head end side of a filling pipe is formed in a measurement smaller than the diameter of a filling port, and the base end side of the filling pipe is formed in a rectilinearly tapered shape so that it is an outer diametrical measurement larger than a filling port (h) diameter. Additionally, a first flexible sleeve 2 to wrap around and adhere on a discharge opening 1a on the head end part of the filling pipe 1, a second flexible sleeve 3 adjacent to the sleeve 2 and a third flexible sleeve 4 are provided on the outer periphery of the filling pipe 1. Consequently, it is possible to materially omit a working process to install the filling pipe and to secure liquid tightness and additionally, it is possible to correspond to change of the diameter of the filling port diameter with the same filling pipe.

摘要： PURPOSE:To easily adjust the gel time of grout, by feeding water into a pump(s) when a curing agent-contg. soln. and an aq. sodium silicate soln. are separately fed to confluence of chemicals with different pumps and the resulting grout is injected into the ground. CONSTITUTION:A soln. contg. a curing agent 2 which can react with sodium silicate to cause gelation thereof is fed to one inlet to a confluence 6 of chemicals with a pump 4. At the same time, an aq. sodium silicate soln. 3 is fed to the other inlet of the confluence 6 with a pump 5, thereby mixing the curing agent-contg. soln 2 with the sodium silicate soln. 3 at the confluence 6. The resulting grout is continuously injected into the ground, while water 1 is fed to the suction port of the pump 4 or (and) pump 4, thereby diluting the curing agent-contg. soln 2 or (and) the aq. sodium silicate soln. 3 and adjusting the gel time of the grout to a desired one.

摘要： PURPOSE:To permit two fluids to react upon each other to be certainly mixed with each other without remaining unreacted portion, on injecting two-part hardening agent into cracks. CONSTITUTION:At the crack generating section of a structure, an injection hole (h) is formed and after that, in a state that a double injecting pipe 30 to be composed of an internal pipe 36 and an external pipe 35 is inserted into the injection hole (h), each fluid of main agent A and hardening agent B is pressure-fed by an injection pump with the discharge fluid quantity to be changed with time. Besides, in the double injecting pipe 30, the two fluids are mixed with each other and is injected into a crack, and the pressure feeding action of the main agent A and the hardening agent B with the injection pump is substantially tuned. Then, the flow rate of each fluid to flow in the mixing section is substantially kept constant with the passage of time.
