Foundation pit close-to-bridge protection structure and foundation pit construction method
The invention provides a foundation pit adjacent bridge protection structure which comprises a plurality of sleeve valve pipes arranged around a pier column bearing platform, steel pipe isolation piles, a foundation pit support, a top beam and a supporting beam, the sleeve valve pipes form an inner grouting area, and the steel pipe isolation piles are arranged along the foundation pit side of the inner grouting area and at least two remaining sides of the inner grouting area. The foundation pit support is arranged along the foundation pit side of the steel pipe isolation pile, the supporting beam comprises a fixing part and a supporting part which is arranged on one side of the fixing part and used for supporting a pier column bearing platform, a first opening is formed in the foundation pit support, a second opening is formed in the steel pipe isolation pile, the fixing part is arranged in the first opening, and the supporting part penetrates through the second opening and wraps a bridge pile foundation adjacent to the supporting part. The top end of the supporting part abuts against the bottom end of the pier column bearing platform. The invention further provides a foundation pit construction method. The combination of the protection structure and the construction method aims to reduce the disturbance of excavation of the foundation pit to the adjacent bridge, improve the stability of the bridge, facilitate the construction of the foundation pit and ensure the construction safety of the area.
本发明提供一种基坑紧临桥梁保护结构，包括多个沿墩柱承台四周设置的袖阀管、钢管隔离桩、基坑围护、冠梁、支撑梁，多个袖阀管形成内注浆区域，钢管隔离桩沿内注浆区域的基坑侧及内注浆区域的剩余至少两侧设置，基坑围护沿钢管隔离桩的基坑侧设置，支撑梁包括固定部、设置在固定部一侧的用于支撑墩柱承台的支撑部，基坑围护上设有第一开口，钢管隔离桩上设有第二开口，固定部设在第一开口中，支撑部穿过第二开口，并包裹与其相邻的桥梁桩基，支撑部顶端与墩柱承台底端相抵。本发明还提供一种基坑施工方法。本发明的保护结构和施工方法结合旨在减小基坑的开挖对紧临桥梁产生的扰动，提高桥梁的稳定性，便于基坑施工并保证该区域的施工安全。
