Large-tonnage pile foundation test loading device

Abstract

The invention belongs to the field of loading equipment, and particularly relates to a large-tonnage pile foundation test loading device. Four anchor rods are fixedly installed at the bottoms of fourdisc bases which are annularly arranged at equal intervals, moving assemblies are arranged at the bottoms of the disc bases, four anchor piles which are annularly arranged at equal intervals are fixedly installed at the tops of the four disc bases, loading assemblies are arranged at the tops of test piles at the center positions of the sides, close to each other, of the four disc bases, stand columns are fixedly installed at the tops of top installation columns of the test piles, four connecting plates which are annularly arranged at equal intervals are fixedly installed on the outer sides ofthe installation columns, the bottoms of annular discs on the sides, away from the installation columns, of the four connecting plates are fixedly installed with the anchor piles on the same disc base, and the bottoms of four inclined supports movably installed on the outer sides of the stand columns are movably installed with the tops of the four connecting plates. The problems that the flexibility of the anchor piles is poor, moving is inconvenient, the connecting steps of the anchor piles and the test piles are too many, and the efficiency of the test pile loading test is influenced are solved.

Description

technical field [0001] The invention belongs to the field of loading equipment and relates to a large-tonnage pile foundation test loading device. Background technique [0002] With the continuous development of the world economy, infrastructure construction has entered a stage of rapid growth, and this trend is more obvious in developing countries. As one of the most widely used and common foundation forms, pile foundation is developing towards larger diameter, longer length and more individual items. At this time, higher requirements must be put forward for the pile foundation engineering test. [0003] The authorized document with the notification number CN106320392B discloses a large-tonnage pile foundation test loading device, including: tapered beams, anchor pile groups, loading system; tapered beams include: columns, diagonal stays, cross braces, connecting systems; each anchor The pile group is set under the node of the diagonal stay rod and the cross brace of the ...
