Construction method of tunnel connection assembly type roadbed and tunnel portal roadbed project
The construction method comprises the following steps that prefabricated roadbed blocks are produced, each prefabricated roadbed block comprises a solid waste discrete structure and a light plate, functional holes are formed in the light plates, at least one functional hole is used for arranging a negative pressure pipe in a penetrating mode, at least one functional hole serves as a connecting hole, and at least one connecting hole is used for connecting the solid waste discrete structures with the light plates; at least one functional hole serves as a water injection hole, and through holes are evenly distributed in the pipe wall of the negative pressure pipe and the pipe wall of the water injection pipe respectively. Construction preparation; connecting anchor rod construction is conducted, specifically, connecting anchor rods are anchored into the preset positions of the tunnel portal slope, and grouting and consolidation are conducted; paving construction is conducted, the corresponding connecting anchor rods penetrate through the connecting holes of the prefabricated roadbed blocks at the side slope position, the prefabricated roadbed blocks outside the side slope position are transversely paved along the tunnel, and negative pressure pipes penetrate through the functional holes; the steps are repeated for layered paving to form a roadbed structure, and vertical joint sealing materials are paved between the adjacent prefabricated roadbed blocks to form a vertical buffer layer; pre-burying a water injection pipe in the roadbed structure through the water injection hole; and performing water ramming compaction and negative-pressure vacuum water pumping.
本发明公开了一种隧道衔接装配式路基的施工方法及隧道洞口路基工程，包括以下内容：预制路基块生产，预制路基块包括固废散体结构以及轻质板，轻质板开设功能孔，至少一功能孔用于穿设负压管，至少一功能孔作为连接孔，至少一功能孔作为注水孔，负压管及注水管的管壁分别均匀分布的开设通孔；施工准备；衔接锚杆施工，将衔接锚杆锚入隧道洞口边坡预设位置并灌浆固结；铺装施工，使对应的衔接锚杆穿设于边坡位置的预制路基块的连接孔，沿隧道横向铺装边坡位置以外的预制路基块，于功能孔穿设负压管；重复步骤分层铺砌形成路基结构，相邻预制路基块之间摊铺竖向填缝料形成竖向缓冲层；经注水孔于路基结构中预埋注水管；水夯密实及负压真空抽水。
