预制挂板T形桩板墙占建筑用地面积少、支挡效果好,广泛应用于临山丘的铁路和公路工程的支挡结构。T形桩板墙按照T形混凝土护壁人工挖土桩施工工艺进行施工,桩板墙一次混凝土浇筑完毕达到强度设计值后,再开挖桩前土,拆除护壁并挂设混凝土预制挂板,这种支挡结构形式施工简单,操作方便,对于山丘支挡是很好的选择。一、总体施工流程放线定桩位及高程→开挖T形桩板墙
Prefabricated hanging plate T-shaped pile wall accounting for less construction land area, retaining effect is good, is widely used in the hills and railway projects supporting structures. T-shaped piled wall in accordance with the T-shaped concrete retaining wall construction of artificial earth-digging pile construction process, pile wall once the concrete pouring strength reaches the design value, and then excavation of the soil before, remove the protective wall and hanging concrete prefabricated hanging plate, which The type of construction retaining structure is simple, easy to operate, for retaining the hill is a good choice. First, the overall construction process pay-off line Stakes and elevation → T-shaped excavation dug wall
