Pipe pile bottom sealing pouring construction method
The invention discloses a pipe pile bottom sealing pouring construction method. The pipe pile bottom sealing pouring construction method comprises the following steps that pipe pile core inserting steel bars are prefabricated in a factory according to pipe pile size data; soil in a pipe pile is cleared to the depth + 100mm required by a drawing and a specification, and dust, laitance, dirt and the like in the pipe pile are cleaned up; when the pipe pile is filled with underground water, an iron wire is wound on a soil bag for pre-bottom sealing; the cement and the mortar are mixed according to the ratio of 1: 3 and is poured into the bottom of the pipe pile for bottom sealing treatment; core filling concrete is poured through high-strength-grade micro-expansion concrete; and the surface of the concrete is coated with a pile head waterproof layer. According to the pipe pile bottom sealing pouring construction method, pipe pile bottom sealing pouring is conducted, the pipe pile core inserting steel bars are prefabricated, pile head cross arm steel bars are omitted, a pile head is waterproof and free of obstruction of the cross arm steel bars, and the coating face is smooth; meanwhile, bottom sealing cushion layers are arranged at the bottoms of the core inserting steel bars, and rusting of trays at the bottoms of the core inserting steel bars is avoided; and factory prefabrication is adopted, compared with original self-designed welding steel bar frames, the construction period is effectively shortened, and the construction progress is accelerated.
本发明公开了一种管桩封底浇筑施工方法，包括以下步骤：根据管桩尺寸数据工厂预制管桩插芯钢筋；管桩内泥土清理至图纸、规范要求的深度+100mm，对管桩内灰尘、浮浆、污杂物等清理干净；当管桩内充满地下水，采用土袋缠绕铁丝预封底；拌和1:3水泥砂浆，浇筑管桩底部，进行封底处理；待采用高强度等级微膨胀混凝土进行浇筑填芯混凝土；对混凝土表面进行涂刷桩头防水层。本发明通过本方法进行管桩封底浇筑，通过预制管桩插芯钢筋，省去桩头横担钢筋，桩头防水无横担钢筋阻碍，涂刷面平整，同时插芯钢筋底部有封底垫层，避免了插芯钢筋底部托盘锈蚀，并且采用工厂预制，相对原先自行设计焊接钢筋架，有效的缩短了工期，加快了施工进度。
