Miniature steel pipe pile sealing and grouting structure
The invention relates to the technical field of civil engineering, in particular to a miniature steel pipe pile sealing grouting structure which comprises a protection assembly and a grouting assembly, the protection assembly comprises a protection cover and a protection cover cover plate, and the protection cover cover plate is fixedly arranged at the top of the protection cover; the grouting assembly comprises a grouting pipe and a grouting core pipe, the upper end of the grouting core pipe is communicated with the grouting pipe, the lower end of the grouting core pipe penetrates through a cover plate of the protective cover and extends into the protective cover, an adjusting nut is arranged on the outer side wall of the grouting core pipe and located at the top of the cover plate of the protective cover, and the grouting core pipe is arranged on the outer side wall of the grouting core pipe. The lower portion of the grouting core pipe is sleeved with a foldable expansion rubber gasket, and the expansion rubber gasket is located in the protective cover. The phenomenon that grout overflows from a gap between the top of the steel pipe and the grouting pipe can be effectively prevented, the grouting pressure is guaranteed, the situation that the pressure of the grout in the steel pipe is too low is avoided, and it is guaranteed that the grout is squeezed out of the pipe from the grout outlet holes in the steel pipe.
本发明涉及土木工程技术领域，具体涉及一种微型钢管桩封口注浆结构，包括防护组件和注浆组件，所述防护组件包括防护罩和防护罩盖板，所述防护罩盖板固定设置在防护罩的顶部；所述注浆组件包括注浆管和注浆芯管，所述注浆芯管的上端与注浆管相连通，注浆芯管的下端穿过防护罩盖板、且伸入所述防护罩内，所述注浆芯管的外侧壁设置有调节螺母，调节螺母位于所述防护罩盖板的顶部，所述注浆芯管的下部套设有可折叠的膨胀橡胶垫片，膨胀橡胶垫片位于所述防护罩的内部。本发明能够有效防止出现浆液从钢管顶部与注浆管之间的缝隙溢出的现象，保证注浆压力，避免钢管内浆液压力偏低，确保浆液从钢管上的出浆孔挤压至管外。
