Gin is the abbreviation for grouting intensity number. it is showed by the product of the final grouting pressure p ( unit : mpa ) on the grouting section and the grouting volume v ( unit : l / m ) on every one meter of the grouting section, which means the energy consumed on every one meter of grouting section. according to gin method, if during the grouting construction, same energy is consumed on every grouting section, i. e. gin keeps to be a constant, an approximately uniform impervious curtain can be obtained
Gin （ groutingintensitynumber ）即灌漿強度值，它用灌漿孔段上最終的灌漿壓力p （ mpa ）和單位灌漿段長度漿液灌注量v （ l / m ）的乘積表示，其含義為單位灌漿段上消耗的能量， gin法灌漿認為在灌漿施工中，保持各灌漿孔段上消耗一致的能量，即保持gin為常數，便可形成一道大致均勻的防滲帷幕。
