Construction method for injecting high-proportion cement into high-pressure jet grouting pile
The invention provides a construction method for injecting high-proportion cement into a high-pressure jet grouting pile. The construction method for injecting the high-proportion cement into the high-pressure jet grouting pile is realized by means of a slurry separation technology, an accurate replacement technology and a diameter-increasing injection technology and by means of a high-pressure jet grouting drill bit of a stirring and slurrying cavity. The defects that the replacement proportion of pile body soil cannot be guaranteed and replaced cement slurry is difficult to collect and treatin the construction of the high-pressure jet grouting pile at the present stage are thoroughly overcome. According to the construction method for injecting the high-proportion cement into the high-pressure jet grouting pile, the pile body can be enhanced and the pile diameter can be increased while saving and efficiency increasing are achieved, so that the construction of the high-pressure jet grouting pile truly achieves high quality, high efficiency, high reliability and high economy.
一种高比例水泥喷入高压旋喷桩的施工方法，依靠浆液分离技术和精确置换技术以及增径喷射技术，借助于所述一种搅拌制浆腔的高压旋喷钻头，实现一种高比例水泥喷入高压旋喷桩的施工方法。彻底解决现阶段高压旋喷桩的施工中，存在桩体土置换比例无法保证和置换出来的水泥浆液难以收集处理的缺陷。本发明所述的一种高比例水泥喷入高压旋喷桩的施工方法在节约增效的同时，既可以增强桩体，又可以增大桩径，使高压旋喷桩的施工真正做到了高质量、高效率、高可靠性和高经济性。
