The invention discloses a basement tower crane foundation pit plugging grouting and reinforcement construction method. The technological process of the basement tower crane foundation pit plugging grouting and reinforcement construction method comprises the following steps in sequence: carrying out base course cleaning; checking the grouting position; carrying out hole arrangement; carrying out hole drilling; carrying out hole cleaning and hole protection; carrying out nozzle arrangement; preparing grout; carrying out grouting, and checking the grouting state repeatedly; waiting for consolidation; and carrying out nozzle dismounting. Aiming at the problem that water leaks or bursts because a basement tower crane foundation pit brick membrane is damaged by water pressure, a stone body whichis novel in structure, high in strength, good in waterproof performance and high in chemical stability is formed; the water impermeability and the bearing capacity of a foundation are improved; it isensured that the impact of water pressure on the brick membrane is prevented; and after the construction is completed, the leak-proof effect can be completely achieved as long as the fact that no water leaks from the brick membrane is guaranteed through 48-72 hours' observation.
本发明公开了地下室塔吊基坑堵漏灌浆及加固施工方法，工艺流程依次为：基层清理→核对灌浆部位→布孔→钻孔→清孔、护孔→布嘴→配置浆液→灌浆，反复检查灌浆→固结→拆嘴；针对水压对地下室塔吊基坑砖胎膜造成破坏，产生渗漏水或涌水问题，形成一个结构新、强度大、防水性能高和化学稳定良好的“结石体”，达到提高地基的不透水性和承载力，确保砖胎膜不受水压的冲击，施工完成后，经过48~72小时观察砖胎膜无水渗出，从而能够完全达到不渗不漏的效果。
