Inclined genesis of deep curtain grout hole and disposal methods 深孔帷幕灌浆孔斜成因与处理
Improving measures for the drilling of solidified grout hole with ingersoll - rand lm - 500c hydraulic drill rig 露天液压钻机钻凿固结灌浆孔的改进措施
Line meter ( m ) and grout take ( t ) method were taken successively for measurement of grouting quantity in china 我国灌浆工程的工程量主要采用灌浆孔进尺(延长米, m )和灌浆注入量( t )两种方法计量。
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 )即灌浆强度值,它用灌浆孔段上最终的灌浆压力p ( mpa )和单位灌浆段长度浆液灌注量v ( l / m )的乘积表示,其含义为单位灌浆段上消耗的能量, gin法灌浆认为在灌浆施工中,保持各灌浆孔段上消耗一致的能量,即保持gin为常数,便可形成一道大致均匀的防渗帷幕。
