Tensile joint prefabricated panel suitable for concrete faced rockfill dam and pressurized repairing inter-joint structure and method
The invention provides a tensional seam prefabricated panel suitable for a concrete faced rockfill dam and a structure and method capable of being repaired through pressurization between seams. The prefabricated panel can be rapidly installed on site, and the problems that a cast-in-place panel is prone to cracking in the strength increasing process, and water stop between the seams is damaged are solved. An inflation steel pipe and a pressurized water grouting steel pipe are pre-buried in the prefabricated panel, and pressurizing detection and repairing can be conducted on the structure between the seams. The W-shaped copper water stop structure at the bottom of the cast-in-place concrete panel is improved into the omega-shaped copper water stop belt suitable for the prefabricated panel, rubber rods and polyurethane foam plates are arranged between noses of the omega-shaped copper water stop belt, seam attaching rubber belts are arranged on the two sides of the omega-shaped copper water stop belt, partition rubber belts are arranged between the upper omega-shaped copper water stop belt and the lower omega-shaped copper water stop belt, and the seam attaching rubber belts and the partition rubber belts are in hot melting connection, so that the water stop effect is good; and the anti-seepage capability is high. According to the pressurizable repairing method, the structure between the seams is checked through subarea pressurizing, and waterstop completeness is ensured. And when the water stop is not closed, grouting is performed on the joint surfaces between the partitions through the reserved pressurized water grouting steel pipes, so that the water stop requirement is met.
本发明提供了一种适应于面板堆石坝的张性缝预制面板和可充压修复缝间结构及方法，预制面板可实现现场快速安装避免了现浇面板强度上升的过程易开裂、缝间止水破坏的问题。该预制面板预埋有充气钢管和压水灌浆钢管，可以对缝间结构进行充压检测及修复。本发明将现浇混凝土面板底部W铜止水结构改进为适用于预制面板的Ω型铜止水带，Ω型铜止水带鼻间有橡胶棒及聚氨酯泡沫板，两侧有贴缝橡胶带，上下Ω型铜止水带之间为分区橡胶带，贴缝橡胶带与分区橡胶带热熔连接，止水效果好，防渗能力高。本发明可充压修复方法，通过分区充压检查缝间结构，确保止水完整。止水不封闭时，通过预留压水灌浆钢管对分区间缝面进行灌浆，达到止水要求。
