The invention relates to the technical field of steel pipe structure columns, and discloses a reverse building method steel pipe structure column rear insertion positioning construction method which comprises the following construction steps that (1) a steel sleeve is inserted downwards; (2) a cast-in-place pile is formed in the pile hole; (3) the steel pipe structure column is tripped into the pile hole, a plurality of jacks are arranged on the periphery of the steel pipe column, the inner ends of the jacks fixedly abut against the steel pipe column, and telescopic shafts of the jacks face the steel sleeve; (4) an ultrasonic detection head is lowered, the ultrasonic detection head obtains the perpendicularity data of the steel pipe column, and the multiple jacks adjust the angle of the steel pipe column through the telescopic shaft till the perpendicularity data meets the set requirement; the telescopic shafts of the jacks jack back the steel sleeve, the perpendicularity of the steel pipe structure column is adjusted, positioning is completed, accurate positioning of the steel pipe structure column is ensured, the construction efficiency is high, the jacks automatically adjust the perpendicularity, repeated utilization can be achieved, positioning is accurate and fast, a large amount of auxiliary operation time is saved, the construction progress is accelerated, and the comprehensive construction cost is low.
Description
technical field [0001] The patent of the present invention relates to the technical field of steel pipe structural columns, in particular, it relates to the construction method of back-insertion positioning of steel pipe structural columns in the reverse method. Background technique [0002] When the deep foundation pit support project adopts the reverse method construction technology, the upper part adopts steel pipe structural piles, and the lower part adopts cast-in-place piles, which is one of the common support forms. [0003] For example, during the construction of the Shenzhen Bay Port Station of Shenzhen Urban Rail Transit Line 13, the average excavation depth of the station is 21m, and the stratum within the site range is distributed from top to bottom as plain fill, silty clay, gravel sand, silty clay, full Weathered siltstone and strong, medium, and slightly weathered granite layers, the thickness of the covering layer above the moderately weathered rock is more t...
