Tubular pile bottom grouting device and using method thereof
The invention relates to the technical field of foundation construction, and aims to provide a tubular pile bottom grouting device and a use method thereof. According to the tubular pile bottom grouting device, a condensation structure formed at the bottom of the tubular pile is large in size, and the frictional resistance between the side wall of the tubular pile and surrounding soil can be increased. The tubular pile bottom grouting device comprises a grouting bag, at least one first grouting pipe and at least one second grouting pipe. The grouting bag can be expanded under the extrusion of internal grout; the first grouting pipe is connected with the grouting bag, and one end of the first grouting pipe extends into the grouting bag; the second grouting pipe is connected with the grouting bag, and the second grouting pipe penetrates through the grouting bag. The grouting device solves the problems that in the prior art, a condensation structure formed at the bottom of a pipe pile through a grouting device is small in size, friction force between the pipe pile and surrounding soil is small, and consequently the effect of improving the bearing capacity of the pipe pile is poor.
本发明涉及地基基础施工技术领域，其目的是提供一种管桩底部注浆装置及其使用方法。这种管桩底部注浆装置在管桩底部形成的凝结结构体积较大并可使管桩侧壁与周围土体摩阻力增加。上述管桩底部注浆装置包括：注浆袋、至少一根第一注浆管和至少一根第二注浆管；注浆袋受内部浆液挤压可膨胀；第一注浆管与注浆袋连接，且一端伸入注浆袋内；第二注浆管与注浆袋连接，且第二注浆管贯穿于注浆袋。本发明解决了现有技术中的注浆装置在管桩底部形成的凝结结构体积小，管桩与周围土体之间摩擦力比较小，导致对管桩承载能力的提高效果较差的问题。
