Double-hole opposite penetrating vibroflotation grouting diaphragm wall structure, wall forming method and wall forming equipment
The invention relates to a double-hole opposite penetrating vibroflotation grouting diaphragm wall structure, a wall forming method and wall forming equipment. The double-hole opposite-penetrating vibroflotation grouting diaphragm wall structure comprises drilling and grouting holes and opposite-penetrating holes, wherein the drilling and grouting holes and the opposite-penetrating holes penetrate into a foundation layer from the ground; the drilling and grouting holes and the opposite-penetrating holes are of grouting structures, and drilling and grouting liquid is poured into the grouting structures. An inter-hole opposite-penetrating body is arranged between the drilling and grouting hole and the opposite-penetrating hole, drilling and grouting liquid of the drilling and grouting hole enters the opposite-penetrating hole from the inter-hole opposite-penetrating body, and a composite grouting body is formed in the inter-hole opposite-penetrating body; and the drilling grouting liquid and the composite grouting body are gradually solidified within a period of time to form the diaphragm wall structure. According to the anti-seepage wall structure, a wall body which is compact in structure, continuous and reliable can be well formed on a complex soft bottom layer, the overall quality of the formed anti-seepage wall completely meets the anti-seepage requirement on engineering, and the anti-seepage wall structure is mainly applied to the vertical anti-seepage field of dike foundations, dam foundations, deep foundation pit excavation water retaining and the like.
本申请涉及一种双孔对穿振冲灌浆防渗墙结构、成墙方法及成墙设备。双孔对穿振冲灌浆防渗墙结构包括自地面深入地基层的钻灌孔与对穿孔；钻灌孔与对穿孔为灌浆结构，其内灌注有钻灌浆液；在钻灌孔与对穿孔之间具有孔间对穿体，钻灌孔的钻灌浆液从孔间对穿体进入对穿孔，在孔间对穿体内形成复合灌浆体；钻灌浆液与复合灌浆体在一段时间内逐渐固化，形成所述防渗墙结构。本发明提供的防渗墙结构能够较好的在复杂松软底层形成结构密实、连续可靠的墙体，且形成的防渗墙整体质量完全满足工程上的防渗要求，主要应用于堤防基础、大坝基础、深基坑开挖挡水等垂直防渗领域。
