[0002] The main reinforcement of the tunnel three-limb grid refers to one of the important components used to reinforce and support the tunnel structure during tunnel construction. The main reinforcement of the grid is usually made of steel bars or steel. Its function is to enhance the stability and bearing capacity of the tunnel structure and prevent the tunnel from deformation, cracking or collapse during use.

[0003] Three-legged grid main reinforcement locators are an auxiliary tool used in tunnel construction to ensure that the three-legged grid main reinforcement is correctly and accurately installed at a specific location in the tunnel structure. These locators are usually specially designed devices that can accurately locate and fix the three-legged grid main reinforcement to ensure its correct position and orientation during construction.

[0011] Furthermore, the outside of the main ribs are fixedly connected with ribs, and the ribs are arranged inside the rib grooves.

[0012] Furthermore, the outside of the main ribs are fixedly connected with first connecting ribs, the bottom of the first connecting ribs are provided with second connecting ribs, and the second connecting ribs are fixedly connected to the outside of the main ribs.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, a plurality of sets of limiting semicircular frames are sleeved on the main reinforcement, the rib grooves on the inner side of the limiting semicircular frames are engaged with the ribs on the main reinforcement, and then the fixed semicircular sleeves and the limiting semicircular frames are locked and fixed by a locking cap.
