Device and method for fixing and secondary deviation correction of pre-embedded steel column in underground diaphragm wall

Abstract

The invention relates to an underground diaphragm wall pre-buried section steel column fixing and secondary rectifying device and method. Steel bases are fixed to wall guiding faces on the two sides through embedded bolts. The four steel bases are fixedly connected with a section steel column through two bars of finish rolling threaded steel, the steel bases and the finish rolling threaded steel are fixed through matched nut cushion plates, one end of each bar of finish rolling threaded steel is connected with a jack, and when the displacement of the section steel column is rectified, the nut cushion plates are loosened, and the jacks are used for enabling the finish rolling threaded steel to be symmetrical and pretightening and tensioning the finish rolling threaded steel so that rectification of the section steel column can be completed. The adopted components of the device are simple, mounting and demounting are convenient and quick, and the device is especially suitable for pre-burying structural members with high precision requirements and not too large weight in an underground diaphragm wall. The device is high in working efficiency, reliable in quality, capable of being reused, relatively low in construction cost and high in economic benefits.

Description

Technical field [0001] The invention relates to a device for fixing and secondary correction of embedded steel columns in underground continuous walls or other similar working conditions, in particular to a device that passes through the device after the structural columns are shifted during concrete pouring The second correction can be carried out before the initial setting of the concrete to ensure the precise positioning of the section steel column. Background technique [0002] At present, the shortage of land resources in cities has resulted in less land occupied by high-rise buildings and the development and utilization of underground space has become more prominent. In order to make full use of the limited ground and space within the red line of the building, and give full play to the investment benefits. Diaphragm walls are no longer purely used as anti-seepage and waterproof, deep foundation pit retaining walls, and more and more underground diaphragm walls are used to ...
