Anchor sealing construction method and auxiliary anchor sealing structure thereof
The invention is suitable for the technical field of bridge construction, and provides an anchor sealing construction method and an auxiliary anchor sealing structure thereof. The anchor sealing construction method comprises the steps that a prestress hole channel and a notch are formed in a web plate, and a steel bundle penetrating through the prestress hole channel is arranged in the web plate;grouting holes and exhaust holes are formed in the web plate at intervals; prestress tensioning is carried out on the steel beams, the steel beams are anchored to an anchorage device, and vacuum auxiliary grouting is adopted for grouting into the prestress hole channels; and concrete is poured into the notch, and the anchorage device is sealed and protected. Grouting holes and exhaust holes are formed in a web plate at intervals; compared with a traditional mode of pouring concrete from bottom to top, the construction method provided by the invention has the advantages that the construction issimple, the concrete in the notch is poured compactly, and the construction quality is guaranteed.
本发明适用于桥梁施工技术领域，提供了一种封锚的施工方法及其辅助封锚构造。本发明所提供的一种封锚的施工方法，包括：在腹板内开设预应力孔道和槽口，在腹板内设置贯穿预应力孔道的钢束；在腹板上开设间隔设置的灌浆孔和排气孔；对钢束进行预应力张拉并锚固在锚具上，采用真空辅助压浆向预应力孔道内压浆；在槽口内灌注混凝土，对锚具进行封闭保护。通过在腹板上开设间隔设置的灌浆孔和排气孔，再自上而下地向灌浆孔内浇灌混凝土，对位于箱梁腹板底面处的槽口内的锚具进行封闭保护，相比传统自下而上浇灌混凝土的方式，本发明提供的施工方法施工简单，槽口内的混凝土浇灌更密实，施工质量有保障。
