Construction method of bituminous coating pile in sandy foundation
The invention discloses a construction method of a bituminous coating pile in a sandy foundation. The construction method is characterized in that the bituminous coating pile is hammered and driven under the protection action of a steel sleeve. The construction method specially comprises the construction steps that the steel sleeve penetrates through a backfill sandy soil layer and is driven into a soft soil layer laid at the bottom of the sandy soil layer; the bituminous coating pile in the steel sleeve is driven into a bearing stratum, and the steel sleeve is clamped, pulled and taken out through a vibratory hammer. Compared with the prior art, the construction method has the advantages that a bituminous coating is completely protected, the effect that negative friction is reduced through the bituminous coating is fully achieved, operation is easy, the project quality is reliable, the adaptability is high, the construction method is particularly applicable to a pile foundation project with the soft soil layer at the bottom and a thick backfill sandy foundation on the top in a covering mode, the problem of the negative friction can be effectively solved, and the construction quality of the pile foundation project is improved.
