A TUNNEL CONSTRUCTION METHOD USING EXPANSION AGENT

摘要

The present invention core issue with the formation of the free surface of the tunnel, Gheshm the order of the extended portion and the periphery As in crushing the rock, the thermite explosives agents, builders and electrolytic reaction rate and leavening agent used in combination with selected material from the fluid, core issue, Gheshm on the expansion unit and the peripheral construction by applying different combinations ratio of the L changje and gunpowder minimize noise and vibration, while related to the shock and a tunnel excavation method using a swelling agent to maximize the penetration rate of the pressure tunnel. To this end, the present invention since the use of a mixture of swelling agent and 75% to 25% or more of powder to increase the explosive power, so to form a free surface in the first issue and the core, the free face Gheshm expansion portion 15 is formed relatively wide Use a combination of leavening agent in% or more powder and less than 85%, and the periphery is enough if you use a mixture of leavening agent in explosives and less than 5% to 95%. There is also the case of using only the swelling agent without the use of powder at all, depending on the installation environment. According to the invention of this structure, the penetration rate in comparison with the case according to the physical power of the various heavy machinery very quickly and is able to be compared with the case of using only the powder to minimize gas, vibration and noise.
