Fertilizer-groove-free self-waterproof construction method for deep foundation pit
The invention relates to the technical field of building construction, in particular to a deep foundation pit fertilizer-groove-free self-waterproof construction method which comprises the following steps that construction preparation is conducted; high-precision slope protection pile construction; high-precision crown beam construction; secondary excavation of the deep foundation pit is controlled; high-precision inter-pile composite soil nailing wall supporting construction is carried out; processing waterproof weak nodes of the structure; waterproof concrete construction; curing the concrete; the method has the beneficial effects that through inward movement of an excavation line, a foundation pit fertile groove is thoroughly eliminated, and the earth excavation and backfill amount is reduced; a structure self-waterproof system is adopted, waterproof engineering is carried out along with concrete pouring, the construction process is simplified, and the construction period is greatly shortened; under the condition of no foundation pit fat groove, a novel cement-based crystallization type waterproof agent containing active substances is added into basement exterior wall concrete, so that exterior wall leakage caused by sinking and tearing of backfilled soil in traditional exterior wall coiled material water prevention is avoided.
本发明涉及建筑施工技术领域，具体为一种深基坑无肥槽自防水施工方法，包括以下步骤：施工准备；高精度护坡桩施工；高精度冠梁施工；深基坑二次开挖控制；高精度桩间复合土钉墙支护施工；结构防水薄弱节点处理；防水混凝土施工；混凝土养护；有益效果为：通过开挖线内移，彻底取消基坑肥槽，减少土方开挖、回填量；采用结构自防水体系，防水工程伴随混凝土浇筑而进行，简化施工流程，极大的缩短工期；在无基坑肥槽的条件下，向地下室外墙混凝土中添加含有活性物质的新型水泥基结晶型防水剂，从而避免传统外墙卷材防水因回填土下沉撕裂而造成的外墙渗漏。
