Waterproof curtain construction method for sandy gravel soil foundation pit
The invention discloses a waterproof curtain construction method of a sandy gravel soil foundation pit, and relates to the field of building construction, and the waterproof curtain construction method comprises the following steps: step 1, measuring the position of a waterproof curtain according to design requirements, and determining the starting point and the ending point of the curtain; 2, leveling a construction area, and checking underground pipelines and lines erected in the air to determine drilling positions; thirdly, the drilling machine enters, and the perpendicularity is detected through a drop hammer drill before drilling; fourthly, the drill rod is sleeved with a PVC sleeve, and center point positioning is conducted through a center line point positioning device; fifthly, the perpendicularity of the drilled hole is checked again; 6, drilling is conducted; and 7, the high-pressure rotary spraying machine enters, a spraying head of the grouting barrel is aligned with the PVC sleeve to downwards rotate to spray water, gas and the prepared cement grout, the PVC sleeve is smashed in the soil body through impact force, the grout is sprayed by a nozzle of the grouting barrel of the high-pressure rotary spraying machine to cut the soil layer, and therefore the waterproof curtain is formed, operation is easy, and the quality of the waterproof curtain can be remarkably improved.
本发明公开了砂卵石土质基坑的止水帷幕施工方法，涉及建筑施工领域，以下步骤：步骤一、根据设计要求，在止水帷幕的位置上进行测量，确定帷幕的起点和终点；步骤二、对施工区域进行平整，对地下管线及空中所架设线路进行排查确定钻孔位置；步骤三、转孔机进入，在开钻前利用吊锤钻头对垂直度进行检测；步骤四、在钻杆上套入PVC套管，通过中线点定位装置进行中心点定位；步骤五、再次检查钻孔的垂直度；步骤六、进行钻孔；步骤七、高压旋喷机进入，注浆筒喷头对准PVC套管向下旋转喷射水、气及配置好的水泥浆液，利用冲击力将PVC套管在土体中打碎，高压旋喷机注浆筒的喷嘴喷射浆液切割土层，从而形成止水帷幕，操作简单，能显著提高止水帷幕质量。
