The invention relates to the technical field of building construction, in particular to a basement tower crane foundation pit leaking stoppage grouting and reinforcing construction method.Width, length and other conditions of oblique drilling holes are determined according to water leakage conditions under different conditions, and compared with vertical drilling holes, slurry can more smoothly enter water seepage gaps in the grouting process through the oblique drilling holes, so that water leakage is avoided, and the construction efficiency is improved. The water seepage gap can be more fully blocked, the pressure maximization can be ensured by repeatedly grouting for multiple times, the hole is filled in and trowelled after the grouting condition is detected, and cement and lime powder are sprayed into the soil below the foundation pit by using a special drill bit, so that the bearing capacity of the foundation can be improved, and the construction efficiency is improved. According to the depth of the foundation pit, concrete is sprayed to the pit wall or the horizontal and vertical baffles and the steel frame are adopted to support the pit wall, deformation of a pit wall supporting structure can be known in time, the pit wall supporting structure can be reinforced or supported conveniently, and the foundation pit can be better reinforced conveniently.
本发明涉及建筑施工技术领域，具体为地下室塔吊基坑堵漏灌浆及加固施工方法，根据不同条件下的漏水情况确定斜向钻孔的宽度和长度等情况，斜向钻孔相较于竖向钻孔，在注浆的过程中可以使得浆体更加顺畅地进入渗水的缝隙中，从而使得渗水缝隙可以被更加充分地堵塞，且多次反复注浆，可以保证压力最大化，并且在检测注浆情况后再将孔洞进行补平抹光，用特制的钻头向基坑下方的土壤内喷射水泥和石灰粉末，可以提高地基的承载力，根据基坑的深度采用向坑壁喷射混凝土或横竖向挡板与钢框架支撑坑壁，可以及时了解坑壁支撑结构的形变，便于对其进行加固或支撑，便于对基坑更好的加固。
