High-pressure jet grouting pile waterproof curtain construction method
The invention relates to the field of building construction and particularly discloses a high-pressure jet grouting pile waterproof curtain construction method. The method comprises the following steps that S1, a construction area is planned, and the ground is cleaned; S2, pilot holes are drilled in a high-pressure jet grouting pile construction line on an edge of the planned area, and soil sampling is conducted through the pilot holes; S3, hole positions needing to be drilled in the high-pressure jet grouting pile construction line are determined according to the soil texture of the soil; S4, mechanical drilling is conducted on the marked hole positions; S5, a rotary spraying pipe is installed on a drilling machine; S6, a jet grouting pile is formed after the cement paste in the drilled hole is solidified; and S7, a building formwork is fixedly installed on an inner wall of the building foundation pit, side faces of the gaps between the adjacent jet grouting piles are sealed through the building formwork, cement paste is poured into the gaps between the adjacent jet grouting piles from the top of the building foundation pit, and a sealing curtain plate is formed after the cement paste is solidified. The method is advantaged in that the technology for forming the sealing curtain plate through pouring is simple, connecting strength of the interval type jet grouting piles can be guaranteed, and meanwhile impermeability of a waterproof curtain of the jet grouting piles is greatly improved.
本申请涉及建筑施工领域，具体公开了一种高压旋喷桩止水帷幕施工方法，其包括如下步骤：S1、施工区域的规划以及地面清理；S2、在规划区域边缘的高压旋喷桩施工线路上钻先导孔，通过先导孔进行土壤取样；S3、根据土壤的土质确定高压旋喷桩施工线路上需要钻孔的孔位；S4、对标识好的孔位进行机械钻孔；S5、在钻机上安装旋喷管；S6、钻孔内水泥浆凝固后形成旋喷桩；S7、在建筑基坑的内壁上固定安装建筑模板，建筑模板将相邻旋喷桩之间间隙的侧面封闭，在建筑基坑的顶部朝相邻旋喷桩之间的间隙内浇灌水泥浆，水泥浆凝固后形成密封帷幕板。浇注形成密封帷幕板的工艺比较简单且能保证间隔式旋喷桩的连接强度，同时大大提高了旋喷桩止水帷幕的抗渗性。
