Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to an anchor cable steel pedestal structure used for foundation pit engineering. Background Art

[0002] Anchor cable refers to the process of anchoring the main cable in the side hole of a suspension bridge. The main cable is divided into many steel bundles and anchored in the anchor ingots. These steel bundles are called anchor cables. Anchor cables can effectively control the displacement of the rock mass, promote its stability, and achieve the purpose of regulating the layer, landslides, dangerous rocks and dangerous stones. At present, in foundation pit support or earthwork support projects, the method of anchor cable fixing is usually used to reinforce the surrounding rock. During construction, workers first use steel strands with certain bending flexibility to anchor them in the deep part of the surrounding rock through pre-drilled holes in a certain way, and then fix the exposed free end of the anchor cable through a steel pedestal pre-fixed on the grid beam. The existing steel pedestal is usually fixed directly on one side of the grid beam with bolts. During construction, the foundation pit is prone to vibration, which causes the steel pedestal to shift in position, thereby failing to reliably and effectively strengthen the anchor cable's reinforcement effect on the surrounding rock.

[0003] Therefore, those skilled in the art provide an anchor cable steel pedestal structure for foundation pit engineering to solve the problems raised in the above background technology. Utility Model Content
