Grouting method and grouting system
The invention discloses a grouting method and a grouting system.The grouting method comprises the following steps that a plurality of drill holes are formed in a grouting curtain line, the drill holes comprise positive pressure drill holes and negative pressure drill holes, the positive pressure drill holes and the negative pressure drill holes are sequentially and alternately arranged, the positive pressure drill holes are divided into a plurality of grouting sections, and the negative pressure drill holes are formed in the grouting curtain line; a sealing plug is arranged at the upper end of the grouting section, close to the lowermost end, of the positive-pressure drill hole, and similarly, the two negative-pressure drill holes adjacent to the positive-pressure drill hole are plugged through the sealing plug to form a plugging section; grouting is conducted on the grouting section at the lowest end of the positive pressure drill hole, and meanwhile water pumping and air pumping are conducted on the plugging sections of the two adjacent negative pressure drill holes; when the grouting section of the positive pressure drill hole reaches the designed grouting pressure, grouting to the grouting section of the positive pressure drill hole is stopped, water pumping and air pumping to the plugging sections of the two adjacent negative pressure drill holes are stopped at the same time, and grouting of one grouting section is completed; and the grouting step is repeated, and grouting is conducted on the positive pressure drill hole from bottom to top in sequence till grouting of the whole positive pressure drill hole is completed.
本发明公开了一种注浆方法和注浆系统，注浆方法包括如下步骤：在注浆帷幕线上开设多个钻孔，钻孔包括正压钻孔和负压钻孔，正压钻孔与负压钻孔依次交替排布，将正压钻孔划分为多个注浆段，在正压钻孔的靠近最下端的注浆段的上端设置密封塞，同样地，在与其相邻的两个负压钻孔内用密封塞封堵形成封堵段；向正压钻孔最下端的注浆段进行注浆，同时对其相邻的两个负压钻孔的封堵段进行抽水和抽气；待正压钻孔的注浆段达到设计注浆压力时，停止向正压钻孔的注浆段注浆，同时停止向与之相邻的两个负压钻孔的封堵段抽水和抽气，完成其中一段注浆段的注浆；重复上述注浆步骤对正压钻孔由下至上依次注浆直至完成整个正压钻孔的注浆。
