Meanwhile, prestress can be applied to the soil body, effective supporting force is formed in the anchor holes, deformation and displacement of the rock-soil body are prevented, and therefore the supporting capacity of the supporting system on the soil body is improved.

The bearing table 12 is used for installing each pre-stress anchor rod 2, one end of each pre-stress anchor rod 2 is immersed in soil, the other end of each pre-stress anchor rod 2 is fixed on the body 11 through the bearing table 12, the bearing table 12 can transfer concentrated stress of each pre-stress anchor rod 2 to the body 11, and the body 11 serves as an integral stress structure to effectively disperse and transfer stress and reduce stress concentration.

According to the invention, the plurality of support plate pieces 1 can be spliced to form a complete support structure, and each support plate piece 1 can be prefabricated in a factory, so that the plurality of support plate pieces 1 can be conveniently spliced into a whole in the construction process of slope support to cover a slope soil body, and the construction of the support structure is completed.

In the specific construction process, as shown in fig. 1-5, the installation of the support plate 1 is started from the slope toe, and no sequential requirement is required for placing and embedding the prestressed anchor rods 2 into the support plate 1.

As shown in fig. 6-9, the prestressed anchor rod 2 comprises an anchor head 21, an outer rod 22 and an inner rod 23, wherein the outer rod 22 is sleeved on the inner rod 23, and one end of the inner rod 23 and one end of the outer rod 22 are connected with the anchor head 21; the outer rod 22 is formed with an expansion part 221 near one end of the anchor head 21, and the expansion part 221 is configured to be expandable when the other end of the outer rod 22 is close to the anchor head 21.

The prestressed anchor rod 2 is an expansion anchor rod structure and can be applied to a support system, and as the expansion part 221 is formed at one end of the outer rod 22 close to the anchor head 21, the expansion part 221 is configured to expand when the other end of the outer rod 22 is close to the anchor head 21, so that the contact and friction force with a rock-soil body around an anchor hole can be enhanced, the contact area between the anchor rod and the rock-soil body is increased, the friction force and the pulling resistance are obviously improved, the prestress is effectively transferred and dispersed, and the overall stability and the bearing capacity of the support system are improved.

In this embodiment, as shown in fig. 11, the bearing platform 1212 further includes a cage 123, where the cage 123 is a skeleton of the bearing base 121, and is made of steel bars, and the steel bar cage 123 extends to the mesh 113 along the thickness direction of the panel 112 for overlapping. The bearing base 121 is formed by a concrete casting cage 123, and the bearing base 121 is fixed to the panel 112 as a whole.

When the pressure-bearing base 121 is prefabricated specifically, the reinforcement cage 123 of the pressure-bearing base 121 is bound, the vertical reinforcement of the cage 123 is bound firstly, the vertical reinforcement on the outermost side of the cage 123 is required to extend to the panel 112 and overlap with the net sheet 113, the overlap length is usually 35d-60d (d is the diameter of the reinforcement), and then the reinforcement inside the cage 123 and the horizontal reinforcement are bound to realize the connection of the reinforcement into a whole. Finally, a side template is built on the panel 112 to wrap the cage 123, concrete is poured on the cage 123, and solidification molding is carried out, so that the manufacture of the pressure-bearing base 121 is completed.

The foregoing embodiment numbers of the present application are merely for the purpose of description, and do not represent the advantages or disadvantages of the embodiments. The foregoing description is only of the preferred embodiments of the present application, and is not intended to limit the scope of the application, but rather is intended to cover any equivalents of the structures or equivalent processes disclosed herein or in the alternative, which may be employed directly or indirectly in other related arts.
