The first connecting component 2 and the second connecting component 3 cooperate to achieve a fixed connection between the two walls 1.

[0033] The first connection component 2 includes a first fixed block 22 and a plurality of first clamping blocks 21, and the second connection component 3 includes a second fixed block 32 and a plurality of second clamping blocks 31. The plurality of first clamping blocks 21 are divided into two rows, and the two rows of first clamping blocks 21 are parallel to each other. The first clamping blocks 21 in each row are evenly arranged on the outer end surface of the wall 1 along the vertical direction. The plurality of second clamping blocks 31 are also divided into two rows, and the second clamping blocks 31 and the first clamping blocks 21 are vertically staggered on the outer end surface of the wall 1. The second clamping block 31 is arranged between two adjacent first clamping blocks 21. A filling cavity 5 for filling the casting material is reserved between the two rows of the first clamping blocks 21. By filling the filling cavity 5 with the casting material, effective sealing of both sides of the wall 1 is achieved. A contact surface is formed between the first clamping block 21 and the second clamping block 31, and the contact surface is arranged downwardly along the inner side of the wall 1 toward the outer side of the wall 1. The first clamping block 21 and the second clamping block 31 are stacked on each other to form a tile-like arrangement, which further reduces the entry of external liquid into the packing cavity 5 and improves the waterproof effect. A sealing plate 6 is arranged on the side of the second clamping block 31 away from the packing cavity 5. The outer end surface of the sealing plate 6 away from the packing cavity 5 and the outer end surface of the wall 1 are in the same vertical plane. The gap between the sealing plate 6 and the other wall 1 is waterproofed by a sealant, which further enhances the sealing effect between the two walls 1.

The interior of the fixing plate 4 is hollow, which helps to enhance the sound insulation effect of the wall 1. A connecting cover 42 is provided at the upper end of the fixing plate 4, and a recess matching the connecting cover 42 is provided at the upper end of the wall 1. The connecting cover 42 is placed downward in the recess of the wall 1 so that the upper end surface of the connecting cover 42 is in the same horizontal plane as the upper end surface of the wall 1. Four bolts 43 are provided on the connecting cover 42, and the four bolts 43 are respectively provided at the four diagonal positions of the connecting cover 42. The bolts 43 are connected to the connecting cover 42, and the bolts 43 pass through one end of the connecting cover 42 and are threadedly connected to the wall 1 to fix the connecting cover 42 and the wall 1. The connection cover 42 is provided with a filling hole 421 connected to the filling cavity 5 , and the casting material is filled into the filling cavity 5 through the filling hole 421 , so as to further fill the gap in the filling cavity 5 .

[0036] like Figure 2 As shown, three fixing rods 41 are arranged at the lower end of the fixing plate 4, and the lower ends of the fixing rods 41 penetrate downwardly through the second fixing block 32, and one end of the fixing rods 41 passing through the second fixing block 32 is inserted into the first fixing block 22, so that the second fixing block 32 and the first fixing block 22 are fixedly connected, thereby enhancing the stability of the wall 1 and extending the service life of the wall 1. Since there is a gap between the fixing plate 4 and the inner wall of the filling cavity 5, and the lower ends of the fixing rods 41 are tapered, it is convenient to insert the fixing rods 41 into the second fixing block 32, thereby improving the construction efficiency.
