Construction method for soil retaining board structure between piles of adjacent slide-resistant piles
The invention discloses a construction method for a soil retaining board structure between piles of the adjacent slide-resistant piles. The construction method comprises the following steps that connecting ribs, reinforcing ribs and U-shaped ribs are anchored to retaining wall concrete together firstly; then the U-shaped ribs and the reinforcing ribs are tied and fixed to a slide-resistant pile reinforcement cage together; a soil body between the piles is excavated in a segmented mode, the soil body is excavated into an arc-shaped structure, back-side bent longitudinal ribs are tied and fixedto the connecting ribs together, front-pile longitudinal ribs and L-shaped reinforcing ribs and the connecting ribs are tied into a whole, and the back-side bent longitudinal ribs are tied and fixed to the front-pile longitudinal ribs together through the use of connecting hoops; a formwork is fixed, and cement mortar is poured; the formwork is removed after the cement mortar is solidified; and the above operation is repeated to complete the construction operation of the soil retaining board structure between the piles of the two adjacent slide-resistant piles. According to the construction method, a retaining wall is fully utilized, the waste of the retaining wall is avoided, the soil retaining capacity of a soil retaining board is improved, the thickness of the soil retaining board is further reduced, and the construction cost is saved; and the soil facing surfaces of the soil retaining board are of arc-shaped structures, and the soil retaining board is changed into a compression-flexure member from a traditional flexural member, so that the safety is improved.
本发明公开了一种相邻抗滑桩桩间挡土板结构的施工方法，先将连接筋、加强筋和U形筋与护壁混凝土锚固在一起；再将U形筋和加强筋与抗滑桩钢筋笼绑固在一起；分段开挖桩间土体，并将其开挖成弧形结构，将背侧弯曲纵筋与连接筋绑固在一起，将桩前纵筋与L形加强筋和连接筋绑扎为一体，利用连接箍筋将背侧弯曲纵筋和桩前纵筋绑固在一起；固定模板，灌注水泥砂浆；水泥砂浆凝固后拆除模板；重复上述操作，完成相邻两抗滑桩的桩间挡土板结构的施工作业。本发明使护壁得到充分利用，避免护壁浪费，提高了挡土板的挡土能力，进而降低了挡土板的厚度，节约施工成本；挡土板的迎土面均为弧形结构，将其由传统的受弯构件变成压弯构件，提高了安全性。
