Grouting anti-seepage treatment method for completely weathered granite stratum
The invention discloses a grouting anti-seepage treatment method for a completely weathered granite stratum. The grouting anti-seepage treatment method comprises the steps that 1, construction preparation is conducted, and a grouting area is delimited; 2, grouting liquid is prepared, and the grouting liquid is supplied in the mode of preparing grout and conveying grout on site; 3, a grouting holeand a suction hole are drilled; 4, cleaning of a drill hole is conducted; 5, casing material is poured; 6, grouting is conducted; 7, hole sealing is conducted, specifically, after grouting is finished, a grout inlet valve is closed for grout closing, after a pointer of a pressure gauge returns to zero naturally, hole sealing is conducted, and pure pressure type grouting and hole sealing are conducted through thick grout; and 8, the backfilling of the suction hole are conducted, specifically, the pure pressure type grouting and hole sealing are conducted through the thick grout, the hole sealing and grouting pressure is 3 MPa, grouting duration is 1 h, and backfilling of the suction hole is finished. According to the grouting anti-seepage treatment method, the geological conditions of completely weathered granite are improved by utilizing a grouting technology, so that the integrity and the anti-seepage performance of the completely weathered stratum are improved.
本发明公开了一种全风化花岗岩地层的灌浆防渗处理方法。所述灌浆防渗处理方法包括：步骤1，施工准备，划定灌浆区区域；步骤2，配置灌浆液，采用现场制浆、输浆的方式供给灌浆液；步骤3，钻设灌浆孔、吸引孔；步骤4，钻孔冲洗；步骤5，灌注套壳料；步骤6，灌浆；步骤7，封孔，灌浆结束后，关闭进浆阀门进行闭浆，待压力表指针自然回零后，进行封孔，采用浓浆进行纯压式灌浆封孔；步骤8，吸引孔回填，采用浓浆进行纯压式灌浆封孔，封孔灌浆压力为3MPa，灌浆持续时间为1h，吸引孔回填结束。本发明所述的灌浆防渗处理方法，利用灌浆技术，对全风化花岗岩地质条件进行改良，提高全风化地层的整体性和防渗性能。
