Reusable secant pile wall positioning device and construction method
The invention relates to a reusable secant pile wall positioning device and a construction method. The device comprises steel guide wall frames, detachable positioning blocks, supporting blocks, telescopic components, a supporting rod and a supporting frame positioning device. The positioning blocks are connected to the guide wall frames through positioning block screws correspondingly. The positioning blocks between the two guide wall frames are opposite pairwise. The guide wall frames are in sliding fit with the supporting blocks. The bottoms of the telescopic components are connected to thetops of the supporting blocks correspondingly. The tops of the telescopic components are connected with supporting rod bolts correspondingly. According to the device, by adjusting the distance between the two guide wall frames, the transverse bore diameter of a secant pile wall is controlled; and while a reinforcement cage is lowered, the positions of the supporting blocks are well set first, then the supporting rod transversely penetrates through lifting lugs of the reinforcement cage, the lowering position and lowering depth of the reinforcement cage are controlled, the protective layer thickness and effective height of the secant pile wall are controlled, so that the pile wall strength is improved, the whole positioning device can be reused, and the effects that the construction precision is high, and material wasting is reduced are achieved.
本发明涉及一种可重复使用咬合桩定位装置及施工方法，该装置包括：钢导墙架、可拆卸定位块、支撑块、伸缩件、支撑杆和支撑架定位装置，定位块通过定位块螺丝连接在导墙架上，两个导墙架之间的定位块两两相对，导墙架和支撑块滑动配合，伸缩件底部连接在支撑块顶部，伸缩件的顶部与支撑杆螺栓连接。该装置通过调节两个导墙架的间距，控制咬合桩的横向孔径；在钢筋笼下放过程中，先设置好支撑块位置，再将支撑杆横穿钢筋笼起吊耳，控制钢筋笼下放位置及下放深度，控制咬合桩的保护层厚度及有效高度，以提高桩身强度，整个定位装置均可重复使用，获得较高施工精度，以及减少材料浪费的效果。
