Further, according to the above design scheme, the prefabricated foundation for the cable ring main unit is characterized in that the grouting hole is formed in the reserved wall groove. Furthermore, grout holes arranged in the reserved wall groove are evenly distributed into two circles.
The invention has the following technical effects: the prefabricated wall panel is manufactured in a factory and transported to the site, the site foundation is leveled, and the bottom plate is laid; then, grouting materials are pre-injected into the grouting holes, and a layer of grouting materials is pre-laid at the middle position of the two circles of grouting holes; and the transverse wall and the longitudinal wall are arranged along the reserved wall slot on the bottom plate, and vertical steel bars in the wall are inserted into the grouting holes.
Vertical reinforcing bar protrusion transverse wall and vertical wall ground part divide into helical structure in the wall of this application, can increase anchor length, improve the anchoring performance of reinforcing bar.
The utility model provides a be equipped with on the bottom plate and reserve the wall groove, guarantee that horizontal wall and vertical wall can accurately install, have the convenient advantage of assembling, improve horizontal bearing capacity of horizontal wall and vertical wall and bottom plate connection position simultaneously.
The utility model provides a grout hole sets to big end up's circular truncated cone shape, when downthehole grout material and reinforcing bar received ascending pulling force, can cramp the reinforcing bar anchor body automatically, especially when inside grout material and edge bonding quality are not good, still can undertake the vertical pulling force of wall body, guarantees the anchoring performance of wall reinforcing bar.
Grouting materials are fully injected into the grouting holes in advance, and can be manually inserted and tamped, so that the compactness of the grouting materials is guaranteed. During construction, the vertical steel bars in the wall are inserted, and redundant slurry is automatically discharged, so that the vertical steel bars in the wall are completely contacted with the slurry, and the pouring connection quality is improved. And the grouting material is laid in advance between the two circles of grouting holes, after the transverse wall and the longitudinal wall are assembled into the reserved wall slot, the grouting material and the slurry overflowing from the grouting holes are pressed and spread out together, the redundant part is extruded out of the reserved wall slot, the contact surfaces of the transverse wall and the longitudinal wall and the bottom plate are automatically grouted, the post grouting process is omitted, the grouting compactness is good, the seepage is prevented, and the bearing performance and the durability of the connection are greatly enhanced.
