The invention discloses a micro-pile geogrid which comprises transverse rib belts and longitudinal rib belts, the transverse rib belts and the longitudinal rib belts are mutually staggered to form a net-shaped grid, the connecting points of the transverse rib belts and the longitudinal rib belts are formed through injection molding, and micro-piles with different heights according to design requirements are manufactured. According to the micro-pile geogrid, the micro-columns higher than the plane of the grid are formed at the connecting points of the rib belts in an injection molding mode, after the grid is laid, the micro-piles are buried in soil or cement stabilized concrete to play a role in fixing the grid, meanwhile, due to the fact that the connecting points are formed in an injection molding mode, the problem that the tensile strength of grid ribs is damaged due to ultrasonic welding at present can be solved, and the service life of the grid is prolonged. And the problem that the design tensile strength of the grille cannot be achieved due to the fact that the grille ribs are stressed to generate displacement is solved.
本发明公开一种微桩土工格栅，包括横向筋带和纵向筋带，横向筋带与纵向筋带互相交错形成网状格栅，横向筋带与纵向筋带的连接点处注塑而成，并制成因设计需要不同高度的微桩。本发明微桩土工格栅在筋带的连接点处注塑成高出格栅平面的微柱，格栅在铺设后，微桩埋土或水泥稳定混凝土里面能起到固定格栅的作用，同时因连接点是注塑而成，能解决现在因超声波焊接造成的损坏格栅筋条抗拉强度，焊接点剥离力低的缺点，解决了因格栅筋条受力产生位移，从而达不到格栅的设计抗拉强度。
