Permanent pavement structure construction method combined with underground engineering cover excavation construction
The invention relates to a permanent pavement structure construction method combined with underground engineering cover excavation construction, and belongs to the field of underground engineering construction.The permanent pavement structure construction method comprises the following steps that after construction of an underground structure is completed, a half-range structure and a retaining wall in a concrete support in an open excavation supporting structure are dismantled; a concrete buttress is constructed between the underground structure and the other half structure, bearing the temporary blanket, in the concrete support so as to support the temporary blanket; the steel latticed columns below the other half-range structure of the concrete are dismantled; plain soil is backfilled into the space above the underground structure; a pouring hole is formed in the top of the temporary blanket, and concrete is poured; and finally, paving a surface layer on the top of the temporary blanket. The concrete is directly poured on the temporary blanket, and the surface layer is poured to form the permanent pavement, so that the construction period is short, and the resource waste is reduced.
本申请涉及一种结合地下工程盖挖施工的永久路面结构施工方法，属于地下工程施工领域，包括以下步骤：在地下结构完成施工后拆除明挖支撑结构中的混凝土支撑中的半幅结构和挡土墙，再在所述地下结构与混凝土支撑中承载有临时铺盖的另外半幅结构之间施工砼支墩，以顶撑所述临时铺盖；拆除所述混凝土的另外半幅结构下方的钢格构柱；向所述地下结构上方的空间回填素土；在所述临时铺盖的顶部开灌注孔，并灌注混凝土；最后在所述临时铺盖顶部铺装面层。本申请通过直接在临时铺盖上灌注混凝土，并浇筑面层形成永久路面，施工工期短，减少资源浪费。
