The invention relates to a grouting type steel pipe pile and a construction method thereof and relates to the technical field of steel pipe pile construction. The problems that a steel pipe pile is constructed through a traditional down-the-hole hammer, the pile forming difficulty is high, and adaptability is poor are solved. The grouting type steel pipe pile comprises a steel pipe pile body formed by a steel pipe. Cement slurry and broken stone are fixed into the steel pipe pile body and the periphery of the steel pipe pile. The method comprises the following steps that firstly, a bottom sealing steel plate is installed; secondly, holing is carried out; thirdly, the steel pipe pile is constructed and stricken; fourthly, one-time grouting is carried out; fifthly, broken stone is thrown; sixthly, second-time grouting is carried out; and seventhly, a crown beam is welded. According to the steel pipe pile and the method, the cement slurry is injected into soil layers around a pile body uniformly ...
