Underwater existing facility protection cushion layer and construction method thereof
The invention discloses an underwater existing facility protection cushion layer and a construction method thereof.The underwater existing facility protection cushion layer comprises a reinforced grating layer, clay, a composite soft mattress and a broken stone hardcore, the clay is laid on the upper surface of the reinforced grating layer, the composite soft mattress is laid on the upper surface of the clay, and the broken stone hardcore is laid on the lower surface of the clay; the reinforced grating layer is laid on the upper surface of the composite soft body mattress, the broken stone hardcore is laid on the upper surface of the composite soft body mattress, the reinforced grating layer, the clay, the composite soft body mattress and the broken stone hardcore are parallel to one another, the reinforced grating layer is filled with broken stone bodies, the reinforced grating layer comprises a plurality of layers of reinforced grating bodies, and the plurality of layers of reinforced grating bodies are vertically stacked. The construction method has the beneficial effects that the reinforced grating structure is adopted as a construction foundation of the protective cushion layer, the foundation bearing capacity of the protective cushion layer is improved and optimized, meanwhile, the vibration load caused by vehicles in the immersed tunnel is dissipated, and the bearing capacity condition needed by construction of the subsequent protective cushion layer is met.
本发明公开了一种一种水下既有设施防护垫层及其建造方法，水下既有设施防护垫层包括加筋格栅层、黏土、复合软体排和碎石垫层，黏土铺设在加筋格栅层的上表面，且复合软体排铺设在黏土的上表面，碎石垫层铺设在复合软体排的上表面，加筋格栅层、黏土、复合软体排和碎石垫层相互平行，加筋格栅层的内部填充有碎石体，加筋格栅层包括若干层加筋格栅体，若干层加筋格栅体的组合方式为垂直堆叠。本发明有益效果：采用加筋格栅结构作为防护垫层的建造基础，提高和优化了防护垫层的基础承载力，同时耗散沉管隧道因车辆引起的振动荷载，满足后续防护垫层建造所需承载力条件。
