Rigid permanent waterproof layer of underground engineering outer wall and construction method of rigid permanent waterproof layer
The invention discloses an underground engineering outer wall rigid permanent waterproof layer and a construction method thereof, and particularly relates to the technical field of underground engineering.The underground engineering outer wall rigid permanent waterproof layer comprises a backfill soil layer, and an ultra-high performance concrete permanent waterproof layer is arranged on the surface of the backfill soil layer. Comprising high bonding strength, high deformation, high crack resistance, high toughness, high tensile strength, high impermeability, high chemical corrosion resistance and high freeze-thaw resistance, namely ultrahigh durability, and the obtained waterproof layer body and the seam have reliable crack resistance, impermeability and waterproof functions, and also have the functions of bearing or reinforcing the structure and the like. The waterproof layer is durable and long-acting and has the same service life as a building. The cement-based composite material waterproof layer with both toughness and rigidity has no aging problem, the waterproof and anti-seepage reliability of construction joints is high, and the problems that underground engineering is prone to seepage and repair is difficult after seepage can be permanently solved.
本发明公开了一种地下工程外墙刚性永久防水层及其施工方法，具体涉及地下工程技术领域，本发明包括回填土层，所述回填土层的表面设有超高性能混凝土永久防水层，本发明通过制备并很好利用了UHPC优异的物理力学性能，包括高粘结强度、高变形与高抗裂能力、高韧性、高抗拉强度，以及高抗渗性能、高抗化学腐蚀性能和高抗冻融性能——超高耐久性，所获得的防水层本体和接缝有可靠的抗裂、抗渗、防水功能，同时还具备承载或加固结构等功能。该防水层耐久长效，工作寿命与建筑物相同。该韧性与刚性兼备的水泥基复合材料防水层，没有老化问题，且施工接缝防水防渗可靠性高，能够永久性地解决地下工程易渗漏、渗漏后修复困难的难题。
