Tunnel portal slope temporary working platform construction method and tunnel portal platform
The invention discloses a tunnel portal slope temporary working platform construction method and a tunnel portal platform. The tunnel portal slope temporary working platform construction method comprises the following steps that S1, construction preparation is conducted; s2, a layer of prefabricated assembly type roadbed modules is laid, hole positions are reserved, the assembly type roadbed modules are filled with sandy materials, and gaps between the adjacent assembly type roadbed modules are filled with the sandy materials; s3, a leveling layer is laid after the assembly type roadbed module of the current layer is laid; s4, the steps S2-S3 are repeated, and the assembly type roadbed modules of the adjacent layers are laid in a staggered joint mode till the designed elevation of the construction platform is reached; and S5, arranging a water filling assembly in the water filling hole in the hole site, installing a negative pressure assembly in the negative pressure hole in the hole site, filling water into the water filling hole through the water filling assembly, and applying negative pressure through the negative pressure assembly to guide the filled water to diffuse towards the negative pressure hole. The temporary working platform is compacted through water ramming in a vacuum drainage consolidation mode, the compaction degree of a roadbed module is guaranteed, the roadbed design quality standard is met, and the potential safety hazards that the platform is prone to sedimentation cracking, disengagement, landslide and the like are eliminated.
本发明公开了一种隧道洞口边坡临时工作平台施工方法及隧道洞口平台，包括以下内容：S1.施工准备；S2.铺设一层预制的装配式路基模块并预留孔位，装配式路基模块内的填充为砂性材料，相邻的装配式路基模块之间间隙填充砂性材料；S3.当前层装配式路基模块铺设完成后铺设找平层；S4.重复步骤S2‑S3，相邻层的装配式路基模块错缝铺设直至达到施工平台设计标高；S5.于孔位中的灌水孔设置灌水组件，于孔位中的负压孔安装负压组件，经灌水组件于灌水孔灌水，经负压组件施加负压引导灌入水向负压孔方向扩散。通过真空排水固结的方式使临时工作平台水夯密实，保证路基模块压实度，满足路基设计质量标准，消除了平台易沉降开裂、脱空、滑坡等安全隐患。
