The invention provides a construction method used for reducing negative friction force of tubular piles. The construction method comprises the following steps of: step I, estimating depth of a negative friction force neutral point, and prefabricating or processing a connecting component, wherein the tubular pile connecting component is used for connecting the upper tubular pile to the lower tubular pile, the lower part of the tubular pile connecting component is fixedly connected with the lower tubular pile, and the upper part of the tubular pile connecting component is in sleeve connection with the upper tubular pile; step II, performing field leveling and pre-filling soil; step III, performing tubular pile construction; and step IV, performing foundation and building construction, and reducing negative friction force. The construction method can solve the post-construction settlement problem of a soft soil foundation, also greatly reduces or eliminates negative friction force, caused by post-construction settlement, used for the tubular piles, reduces quantity of foundation piles which resist negative friction force, achieves the purposes of being stable, economical and reasonable in structure, and has a very good use value and a very good popularization value.
