Document Type and Number:
WIPO Patent Application WO/2023/207250
Kind Code:
A1
Abstract:
Provided in the present invention is a construction method for rapidly driving a trestle steel pipe pile into sloped bare rock. The construction method comprises the steps: (1) mounting a cantilever Bailey platform; (2) mounting universal beams; (3) mounting and fixing a steel casing; (4) mounting a drilling rig and punching a hole; (5) feeding and lengthening the steel casing; (6) forming the hole; (7) filling the hole with bagged cement or bagged concrete dry material; (8) pulling out the casing, and removing a drilling rig; and (9) inserting and impacting the steel pipe pile for piling: driving the steel pipe pile, repeatedly impacting and lifting same for several times so as to cause the cement or dry material in the hole to fully react with water, and anchoring a pile tip to complete piling construction on the bare rock. In the present invention, a restraint frame for suspension of the casing and the drilling rig are installed by taking an extension cantilever structure formed by an overpass trestle as a drilling platform, and arrangement of an auxiliary drilling platform or usage of a floating pile driver are not needed, thus reducing construction procedures and engineering costs.
