Protection structure for adjacent building in tunnel construction
The invention discloses a protection structure for an adjacent building in tunnel construction. The protection structure comprises a foundation pit, the adjacent building, a cast-in-place steel wire mesh protection slope, a fixed baffle, two-end protection arms, a U-shaped formwork and a reinforcing forming mechanism. The cast-in-place steel wire mesh protection slope is installed at the inner side of the side, close to the adjacent building, of the foundation pit, and the fixed baffle is installed at the outer side of the cast-in-place steel wire mesh protection slope; and the two ends of the outer side of the fixed baffle are each provided with one two-end protection arm, the U-shaped formwork is installed at the outer side of the fixed baffle, the reinforcing forming mechanism is installed in the U-shaped formwork, and the reinforcing forming mechanism can fill and pour mud jacking liquid in the U-shaped formwork to reinforce a near-edge foundation. According to the protection structure, an open-cut tunnel engineering slope is preliminarily protected through the cast-in-place steel wire mesh protection slope and the fixed baffle, and then the foundation of the adjacent building is reinforced through the reinforcing forming mechanism, so that the adjacent building is prevented from deviating due to foundation settlement.
本发明公开了一种隧道施工邻近建筑物保护结构，包括基坑、临近建筑物、现浇钢丝网护坡、固定档板、两端护臂、U形模板、加固成型机构，述基坑与临近建筑物相近一边内侧安装有现浇钢丝网护坡，所述现浇钢丝网护坡外侧安装有固定档板，所述固定档板外侧两端均安装有两端护臂，所述固定档板外侧安装有U形模板，所述U形模板内部安装有加固成型机构，所述加固成型机构可将U形模板内部填充浇筑压浆液体，对临边地基基础加固。本发明通过现浇钢丝网护坡以及固定档板初步对明挖隧道工程边坡进行防护，其次通过加固成型机构对临近建筑物地基基础进行加固，防止临近建筑物因地基沉降发生偏移。
