Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1 to fig. 3, a slip casting stock structure, including stock main part 1, the welding has only thick liquid board 2 in stock main part 1, install slip casting volume control subassembly in the one side of only thick liquid board 2 in stock main part 1, a plurality of firm parts are installed to the opposite side. After the anchor rod main body 1 is placed in the anchor hole, the stability of the anchor rod main body 1 is ensured through the stabilizing part. The grouting flow and the grouting amount are controlled through the grouting amount control assembly, and the phenomenon of slurry overflow is avoided.
The grout stop plate 2 is perpendicular to the anchor rod body 1 and close to the upper end of the anchor rod body 1.
The slip casting volume control subassembly includes bearing cylinder 3, conduction rotary column 8 and only starch ball 9, and bearing cylinder 3 fixed welding is on the outer disc of stock main part 1, is equipped with interior sphere in the stock main part 1, only starch ball 9 is located this interior sphere to with interior sphere swing joint, only processing has the grout hole on the starch ball 9, the one end of conduction rotary column 8 with only starch ball 9 and be connected, middle part and bearing cylinder 3 swing joint, the other end extends outside bearing cylinder 3. When in use, the diameter of the grout stopping ball 9 is matched with that of the inner spherical surface. The slurry stopping ball 9 has the functions of blocking slurry and controlling the flow rate of the slurry.
