Pile plate structure for shield approaching construction protection pipeline and construction method of pile plate structure
The invention belongs to the field of tunnel engineering construction, and particularly relates to a pile plate structure for protecting pipelines in shield approaching construction and a construction method of the pile plate structure. The pile plate structure comprises a plurality of cast-in-situ bored piles, pipeline protection plates and pipeline protection cylinders, the pipeline protection plates are fixed to the pile tops of the cast-in-situ bored piles, and the pipeline protection cylinders are fixed to the upper portions of the pipeline protection plates. The pipeline protection plate is of a three-layer structure and sequentially comprises a prefabricated reinforced concrete plate, a PE insulating plate and a plain concrete cushion layer from top to bottom. A plurality of reserved steel bars are arranged on the pile top of each cast-in-situ bored pile, the ends, extending out of the pile body, of the reserved steel bars are inserted into the pipeline protection plate, the tops of the reserved steel bars are in a threaded shape and used for being matched with locking nuts, and fixed connection between the cast-in-situ bored piles and the pipeline protection plate is achieved. The pile plate structure provided by the invention is suitable for the condition that underground pipelines need to be migrated and modified due to short-distance underneath-penetrating shield tunnels, and meets different scales, distances and migration and modification protection schemes of various pipelines.
本发明属于隧道工程施工领域，具体涉及一种用于盾构近接施工保护管线的桩板结构及其施工方法。该桩板结构包括若干钻孔灌注桩、管线保护板和管线保护筒，所述管线保护板固定于钻孔灌注桩的桩顶，所述管线保护筒固定于管线保护板的上部。所述管线保护板包括三层结构，自上至下依次为：预制钢筋混凝土板、PE绝缘板和素混凝土垫层。每个钻孔灌注桩的桩顶设置有多根预留钢筋，其伸出桩体的一端插设于管线保护板中，预留钢筋的顶部为螺纹状，用于与紧锁螺母配合，实现钻孔灌注桩和管线保护板之间的固定连接。本发明提供的桩板结构适用于地下管线因近距离下穿盾构隧道需进行迁改的情况，满足各类管线不同规模、间距及迁改保护方案。
