After the anchoring cable is grouted, the slope reaction force component cannot be poured in time, and the prestress cannot be applied in time, so that the deformation of the slope is further deteriorated.

[0005] However, the assembly type frame beam is a slope reaction force component, and these reaction force components are generally solid reinforced concrete structures. Because the components need to bear a large anchoring rod tension, the volume and weight of the components are relatively large, and generally a single component weighs several tons to tens of tons, the transportation cost is high, and the hoisting is extremely difficult.

[0006] Therefore, the utility model provides a hollow fishbone type cross beam which reduces the weight of the component. UTILITY MODEL CONTENT
