【多选题】关于注浆法的说法中,正确的是( )
A.
注浆法是将浆液注入岩土的孔隙、裂隙或空洞中,浆液经扩散、凝固、硬化以减少岩土的渗透性,增加其强度和稳定性,达到岩土加固和堵水的目的
B.
根据矿山井巷工程注浆工作与井巷掘进工序的先后次序进行分类,分为预注浆法和后注浆法
C.
预注奖法是在凿井前或在井筒掘进到含水层之前所进行了注浆工程,又可分为地面预注浆和工作面预注浆两种
D.
后注浆法是在井巷掘砌之后所进行的注浆工作,目的是减少井筒涌水,控制井壁和井帮的渗水并加强永久支护
【多选题】关于压水试验,下述说法正确的是( )。
A.
试验段长度可根据地层的单层厚度、裂隙发育程度等因素确定,一般为5~10m,若岩芯完好,可适当加长试验段,但不宜大于10m,可利用专门的活动栓塞分段隔离
C.
当控制某设计压力值呈稳定后,每隔30m测得压入水量。
D.
若进行简易的压水试验,稳定标准可放宽到最大值与最小值之差小于最终值10%
【单选题】瘫痪时产生 “ 塌肩 ” 体征的骨骼肌是?
【多选题】以下关于注浆堵水说法正确的有()
A.
注浆堵水主要作用是封堵裂隙,隔离水源,堵塞水点,以减少洞内涌水量,改善施工条件
B.
注浆浆液常用的有:水泥浆液、水泥-水玻璃浆液以及各种化学浆液
D.
注浆扩散半径与岩石裂隙大小、浆液粘度、凝固时间、注浆量无关,只与注浆速度和压力有关
