| description | The invention discloses a quicksand layer cast-in-situ bored pile structure and a construction method thereof. The quicksand layer cast-in-situ bored pile structure comprises a quicksand layer, a bearing stratum arranged below the quicksand layer, a group of high-pressure jet grouting piles arranged in the quicksand layer and cast-in-situ bored piles arranged in the group of high-pressure jet grouting piles. The high-pressure jet grouting piles are annularly arranged, and the bottoms of the high-pressure jet grouting piles penetrate through the quicksand layer, so that solidification of the quicksand layer can be effectively guaranteed, and lateral plugging for driving is provided for the cast-in-situ bored piles; through the arrangement of the cast-in-situ bored piles, the cast-in-situ bored piles to be constructed and the high-pressure jet grouting piles can be overlapped, effective implementation of the cast-in-situ bored piles is guaranteed, and the cast-in-situ bored piles and the high-pressure jet grout |
