Abstract

The invention provides an adjustable single-pile foundation for a boarding bridge rear pillar. The adjustable single-pile foundation is used for mounting a rotating platform of a boarding bridge and further supporting all sorts of loads of the boarding bridge. The rotating platform is connected with a slewing bearing and an upper flange of the rear pillar through a bottom flange. The rear pillar is connected with a supporting flange of an adjusting pillar through a lower flange. After the position of the adjusting pillar is determined and the adjusting pillar is adjusted to be horizontal, theadjusting pillar and a single pile can be connected into a whole through grouting treatment. The invention further discloses a construction method of the adjustable single-pile foundation for the boarding bridge rear pillar. Compared with an existing boarding bridge rear pillar foundation, the mounting process is simple, engineering cost is low, and the technical risks of boarding bridge collapsing caused by foundation bolt brittleness are eliminated.

Description

technical field [0001] The invention relates to the technical field of airport ground equipment, in particular to a single pile foundation for a rear column of a boarding bridge and a construction method thereof. Background technique [0002] The self-weight and external load of the airport boarding bridge are mainly borne by the rear column and its foundation and the walking lifting column. Existing boarding bridges use pre-embedded anchor bolts to fix the rear columns on the multi-pile foundation. Before embedding the anchor bolts, at least 4 steel piles need to be driven in, and sinking platforms are made on the steel piles, and then cast Anchor bolt anchor cages consisting of 6 to 8 high-strength anchor bolts are pre-embedded. After the rear columns are in place, expansion cement needs to be filled. The installation and construction process is very complicated and the project cost is high; moreover, the anchor bolts are made of high-strength steel. , heat treatment, eas...
