Air bag hole sealing type cloth bag grouting method
The invention provides an air bag hole sealing type cloth bag grouting method. The air bag hole sealing type cloth bag grouting method comprises the following steps that a cloth bag provided with a grout overflow hole is placed into a drill hole, an elastic air bag used for sealing the drill hole is fixed on a grouting pipe, the elastic air bag is connected with an air pump through an air pipe, the grouting pipe is put into a first section of grouting position in the cloth bag before grouting, the air pump is utilized to inflate the elastic air bag through an inflation pipe, the outer side wall of the elastic air bag abuts against the inner side wall of the drill hole, the elastic air bag is inflated to a certain pressure to block the drill hole, then grouting is conducted, and cement grout permeates into a foundation through the grout overflow holes in the cloth bag; and after the first section of grouting is completed, the elastic air bag is deflated, then the grouting pipe is lifted up, then the elastic air bag is inflated, second section of grouting is started, and the process is circulated until the whole drilled hole grouting is completed. The technical scheme provided by the invention has the beneficial effects that the advantages of a cloth bag pile and grouting reinforcement are fully combined, the reinforcement range can be controlled, a good grouting effect can be achieved, the formed pile foundation structure can be ensured to be a preset reinforcement body, and the cost is low.
本发明提供一种气囊封孔式布袋注浆方法，将开设有溢浆孔的布袋置入钻孔内，将用于封堵钻孔的弹性气囊固定在注浆管上，弹性气囊通过气管与气泵连接，注浆前先将注浆管下入布袋内第一段注浆位置，利用气泵通过充气管向弹性气囊内充气，使弹性气囊外侧壁与钻孔内侧壁相抵，将弹性气囊充气至一定压力封堵钻孔，然后注浆，水泥浆液通过布袋上的溢浆孔向地基渗透。第一段注浆完毕后将弹性气囊放气，然后上提注浆管，再将弹性气囊充气，开始第二段注浆，循环此过程直至整个钻孔注浆完成。本发明提出的技术方案的有益效果是：充分结合了布袋桩和注浆加固的优点，既能控制加固范围，达到良好的注浆效果，又能够保证形成的桩基结构为预定的加固体，成本低。
