Double-layer self-circulation pressure-maintaining grouting pipe
The invention relates to a double-layer self-circulation pressure-maintaining grouting pipe. The double-layer self-circulation pressure-maintaining grouting pipe comprises a grouting pipe body, wherein the grouting pipe body comprises an inner pipe and an outer pipe which are arranged in a sleeving mode, the inner pipe and the outer pipe communicate with each other, and slurry outlet holes are formed in the outer pipe; meanwhile, the inner pipe and the outer pipe are connected with a grouting pump through a communicating pipe and a circulating pipe correspondingly; and meanwhile, expansion sleeves are further arranged on the outer pipe in a sleeving mode, and the expansion sleeves are connected with the communicating pipe through expansion pipes. When the double-layer self-circulation pressure-maintaining grouting pipe is used, slurry firstly enters the inner pipe, then enters the outer pipe from the inner pipe, and finally is grouted into a soil layer from the slurry outlet holes; the slurry is buffered through the design of the inner pipe and the outer pipe, so that the pressure change amplitude and the vibration amplitude of the slurry are reduced; meanwhile, the slurry is drained to the far end of the grouting pipe body through the adjustment of the hole diameter and the distribution density of the slurry outlet holes, so that the uniform distribution of the slurry is guaranteed; and the expansion sleeves at the two ends of the grouting pipe body fix the grouting pipe body into mounting holes after being expanded, so that the vibration of the grouting pipe body is further reduced, and the grouting quality is improved.
本发明涉及一种双层自循环保压注浆管，包括注浆管，其中注浆管包括相互套置的内管和外管，内管与外管相互连通，且外管上设置有出浆孔；同时内管和外管分别通过连通管和循环管与注浆泵相连；同时在外管上还套置有膨胀套，膨胀套通过膨胀管与连通管相连；本发明使用时浆液首先进入内管，再从内管进入到外管，并最终从出浆孔向土层中注浆；其通过内外管的设计对浆液进行缓冲，从而降低浆液的压力变化幅度和震动幅度；同时通过出浆孔孔径及分布密度的调节向注浆管的远端引流，从而保证浆液的均匀分布；注浆管两端的膨胀套在膨胀后将注浆管固定于安装孔内，从而进一步降低了注浆管的震动，提高注浆质量。
