Embedded positioning system for connector in underground diaphragm wall and construction method of embedded positioning system
The invention discloses an underground diaphragm wall inner connector pre-embedding positioning system and a construction method thereof, and the underground diaphragm wall inner connector pre-embedding positioning system comprises an underground diaphragm wall main reinforcement, a U-shaped positioning steel plate welded on the underground diaphragm wall main reinforcement, a connector welded on the U-shaped positioning steel plate through a positioning hole, and a first connecting steel bar connected on the connector, the connector is arranged in the groove body of the U-shaped positioning steel plate, the extruded sheet covers the connector and is arranged in the groove body of the U-shaped positioning steel plate, and the bolt fixedly connects the U-shaped positioning steel plate with the extruded sheet through a plate hole of the U-shaped positioning steel plate. The connector positioning dislocation caused when a reinforcement cage is lowered or underwater concrete is poured can be avoided, it can be guaranteed that the connector is not polluted by slurry and concrete under the protection of the extruded sheet, connector threads can be prevented from being rusted and damaged by chiseling, the connector positioning accuracy is high, and the construction quality is good; the construction quality of combining the two walls into one is improved, and water leakage at the connection node position can be prevented.
本发明公开一种地连墙内接驳器预埋定位系统及其施工方法，该地连墙内接驳器预埋定位系统包括地连墙主筋，焊接在地连墙主筋上的U型定位钢板，通过定位孔焊接在U型定位钢板上的接驳器，连接在接驳器上的第一接驳钢筋，覆盖接驳器设置在U型定位钢板的槽体内的挤塑板，以及通过U型定位钢板的板孔将U型定位钢板与挤塑板固定连接的螺栓。本发明能够避免下放钢筋笼或浇筑水下混凝土时导致接驳器定位错位，能够保证接驳器在挤塑板的保护下不被泥浆及混凝土污染，能够避免接驳器丝牙锈蚀、被凿坏，还具有接驳器定位精度高、施工质量好的优点，提高了两墙合一的施工质量，以及能够防止接驳节点位置出现水渗漏。
