[0034] It is convenient to tighten the first reinforcing rib 3 and the second reinforcing rib 18 against the inner side of the transverse formwork 1 and the inner side of the side formwork body 17 respectively. The lengths of the transverse support plates 9 and the longitudinal support plates 10 are cut according to the shapes of the first frame 15 and the second frame 19. A plurality of transverse support plates 9 and a plurality of longitudinal support plates 10 divide the first frame 15 and the second frame 19 into a plurality of small square structures.

[0035] Furthermore, rubber pads are provided on the outer edges of the four sides of the first frame 15 and the second frame 19 to improve the tightness between the first frame 15 and the transverse template 1, and the second frame 19 and the side template body 17.

The first frames 15 on the inner sides of the two facing horizontal templates 1 are arranged facing each other. The connecting grooves 14 on the first frame 15 are arranged facing each other. After the two adjacent horizontal templates 1 are threadedly connected, the two horizontal support platforms 8 that are in contact jointly support the horizontal brace 4 upward, and the lower ends of the front and rear ends of the horizontal brace 4 The side inner walls are respectively tightly attached to the outer side walls of the bottom plate 7 of the opposite horizontal formwork 1, and the upper outer walls at the front and rear ends of the cross brace 4 are tightly attached to the inner side walls of the opposite first frame 15, so that the upper outer walls 4 at the front and rear ends of the cross brace 4 are tightly attached to the first frame 15. According to the on-site construction environment, the connection position of the cross brace 4 and the first frame 15 is adjusted up and down along the connecting groove 14 to improve the accuracy of the installation position of the cross brace 4 where there is a height difference in the shield wall.

[0038] Furthermore, gaskets are arranged around the connecting groove 14 of the first frame 15, and gaskets are arranged on the upper outer wall and the lower inner wall of the cross brace 4. When the upper outer wall of the cross brace 4 is tightly attached to the first frame 15, the gasket can increase the friction, thereby improving the tightness of the connection between the cross brace 4 and the first frame 15. Arranging a gasket on the lower inner wall of the cross brace 4 can increase the friction between the lower inner wall of the cross brace 4 and the cross template 1, thereby preventing the cross brace 4 from sliding.

[0039] In another possible embodiment, a plurality of threaded holes are arranged at intervals along the height direction of the first frame 15 at the left and right ends of the protruding plate on the upper part of the first frame 15 installed in the horizontal template 1, and the positions of the threaded holes at the left and right ends of the protruding plate are symmetrical. After the cross brace 4 is adjusted up and down along the height direction of the first frame 15, bolts are respectively passed through the threaded holes 13 on the cross brace 4 and the threaded holes on the first frame 15 to fix the position of the cross brace 4 and the first frame 15.

The left and right sides of the lateral end of the beam bottom mold 12 located between the inner walls of the two opposing transverse mold plates 1 extend horizontally toward the first frame 15 respectively, so that the two end portions of the beam cross mold 11 installed on the beam bottom mold 12 along the length direction can be tightly attached to the first frame 15, thereby realizing the threaded connection between the beam cross mold 11 and the first frame 15.

[0042] Furthermore, a crossbeam bottom mold 12 is installed at the bottom of two adjacent cross mold plates 1, so that the two vertical ends of the crossbeam bottom mold 12 are respectively upward and tightly attached to the outer side walls of the two opposing cross mold plates 1, the vertical ends of the crossbeam bottom mold 12 are threadedly connected to the two adjacent cross mold plates 1, and the horizontal ends of the crossbeam bottom mold 12 are located at the bottom of the cross mold plates 1 and tightly attached to the bottom of the cross mold plates 1, which can improve the stability of the sump combination mold.
