Sleeve valve pipe grouting method
The invention discloses a sleeve valve pipe grouting method. The sleeve valve pipe grouting method comprises the following steps that S1, exhaust holes and grouting holes are formed and drilled; s2, after hole forming and drilling construction of the exhaust holes and all the grouting holes is completed, exhaust pipes are installed at the exhaust holes, sleeve valve pipes are installed at the grouting holes, and the sleeve valve pipes and the exhaust pipes are fixed by sealing holes; s3, grouting filling operation is conducted through an intermittent and sequential grouting method according to the grouting amount; and S4, the pipe is pulled out, and a hole opening is blocked. According to the method, the soil dissolving hole condition around the pile is explored based on advanced drilling, different numbers of grouting holes and exhaust holes are arranged in a classified mode according to the height of the soil dissolving hole, drilling holes in the original pile position serve as the exhaust holes, exhaust pipes are arranged at the pile position, the drilling time and cost are saved, and the construction efficiency is improved; cement paste is injected into the center of the pile position from outside to inside through the sleeve valve pipe, water glass is doped into the grouting holes in the periphery, a circle of similar curtain is formed, and finally the aim of cost economy and controllability is achieved by controlling the grouting amount while the karst cave pretreatment effect is achieved.
本发明公开了一种袖阀管注浆方法，包括如下步骤：S1、布置并钻设排气孔和注浆孔；S2、在排气孔和所有注浆孔的成孔钻孔施工均完成后，在排气孔处安装排气管并在注浆孔处安装袖阀管，通过封闭洞口固定袖阀管和排气管；S3、根据注浆量采用间歇分序注浆法进行注浆填充作业：S4、拔管并封堵孔口。本发明基于超前钻孔探查桩周围的溶土洞情况，根据溶洞高度分类设置不同数量的注浆孔及排气孔，利用原有桩位的钻探孔作为排气孔并在桩位处设排气管，节约了钻孔的时间及成本，提高了施工效率，采用袖阀管由外向桩位中心注水泥浆，并在外围注浆孔掺加水玻璃，形成一圈类似帷幕，最终在达到溶洞预处理效果的同时，通过控制注浆量实现了成本经济可控的目的。
