Underground engineering single-wall prefabricated structure full-life-cycle waterproof system
The invention provides an underground engineering single-wall prefabricated structure full-life-cycle waterproof system, a cast-in-place concrete structure and a prefabricated diaphragm wall form a single-wall prefabricated structure, the single-wall prefabricated structure is provided with a vertical seam and a horizontal construction seam, two seam sealing water stop strip bags filled with liquid are arranged in the vertical seam, and a waterproof structure is arranged in the vertical seam. A grouting pipe and two water stop rubber strips are pre-buried in the horizontal construction joint, grouting is conducted once after construction is finished, and when the construction joint is opened and leaks due to structural deformation in the operation period, grouting and water stop can be conducted in time in the whole life cycle. The method starts from the principle that the waterproof design of an underground structure should follow'prevention is dominated, rigidity and flexibility are combined, multiple defense lines are arranged, measures are adjusted to local conditions, and comprehensive treatment is carried out ', and self-waterproofing of an underground continuous wall and a cast-in-place reinforced concrete structure is determined as the basis; a waterproof system of the whole life cycle from the construction stage to the operation stage is formed by the measures of a prefabricated single wall structure vertical seam, a prefabricated single wall and waterproof structures of cast-in-place slab construction joints of all layers of the structure and a repeatable grouting pipe.
本发明提供一种地下工程单一墙预制结构全生命周期防水体系，现浇混凝土结构和预制地连墙组成单一墙预制结构，单一墙预制结构有竖缝和水平施工缝，在竖缝内通过两道后充液的接缝密封止水条囊、防水结构，水平施工缝内预埋一道注浆管和两道止水胶条，在施工结束后注浆一次，在运营期结构变形引起施工缝张开渗漏时，可全寿命周期的及时注浆止水。本发明从地下结构防水设计应遵循"以防为主、刚柔结合、多道防线、因地制宜、综合治理"的原则出发，确立以地下连续墙和现浇钢筋混凝土结构自防水为根本，附以预制单一墙结构竖缝、预制单一墙与结构各层现浇板施工缝的防水构造及可重复注浆管措施，形成从施工阶段到运营阶段全生命周期的防水体系。
