Method for detecting compactness of sand filling steel pipe pile and auxiliary tool
The invention relates to a method for detecting the compactness of sand filled a steel pipe pile and an auxiliary tool, and relates to the technical field of bridge engineering construction. The method comprises the following steps: sampling and drying a sand sample forming tap sand; dividing the dried sand sample into a plurality of parts, and preparing into a plurality of parts of samples with different water contents; respectively carrying out a compaction test on each sample to obtain the dry density of each compacted sample; calculating the maximum dry density according to the moisture content and dry density data of the plurality of samples; sampling the tap sand, calculating the actually measured dry density, and comparing the actually measured dry density with the maximum dry density for analysis. The auxiliary tool includes a compaction device including a compaction barrel assembly and a compaction hammer assembly, the compaction barrel assembly including a compaction barrel body; the compaction hammer assembly is used for compacting the sand sample; the auxiliary tool also comprises a sampling device for sampling. According to the invention, the actually-measured dry density and the maximum dry density of the sand sample corresponding to the tap sand are calculated, contrastive analysis is conducted, and whether the sand filling compactness in the steel pipe pile is qualified or not is verified.
