[0029] The thin-walled template comprises a front template 4, a rear template 11, a side template 2 and an inner support plug plate 1; the front template and the rear template are arranged with a back-to-back spacing on an XZ vertical plane, and a Z-direction through slot is arranged at the spacing between the front template and the rear template; the inner support plug plate is inserted in the Z direction in the slot; the top and bottom of the front template and the top of the rear template are bolted to a corner template 3 extending in the X direction, and the inner support plug plate provides Y-direction inner support and Z-direction demoulding power to the opposite surfaces of the front template and the rear template; the side template is blocked in the Y direction and fixedly connected to the Y-direction ends of the front template and the rear template.

[0030] Preferably, a plurality of inner edge plates 9 are fixedly provided on the facing surfaces of the front template and the rear template, the plurality of inner edge plates extend in the X direction and are spaced apart in the Z direction, the upper portion of the inner edge plates is attached to the facing surface of the front template or the rear template, the middle portion of the inner edge plates gradually protrudes into the insertion gap, and the bottom of the inner edge plates is formed with a hanging surface 10 bent toward the facing surface of the front template or the rear template.

[0031] Preferably, a plurality of groups of arc-shaped pressing edges 7 and flat plate hanging edges 8 corresponding to the inner edge plates are arranged at intervals on the inner support plug plate;

[0032] The cross section of the arc-shaped pressing edge is circular, and the outer periphery of the arc-shaped pressing edge is slidably fitted on the middle part of the inner edge plate, and the arc-shaped pressing edge provides an inner supporting extrusion force for the gradually changing convex surface in the middle part of the inner edge plate;

[0036] The working principle of the present invention is:

[0037] The thin-wall template of the water outlet hole of the ship lock chamber bottom plate of the present invention is a casting template for the hole wall around the water outlet hole formed by a front template, a rear template, two side templates and three corner templates.

[0038] When installing the formwork, first assemble it on the ground. When assembling, first stack the front and rear formwork with their backs facing each other, then insert the inner support plate from one side. At this time, the arc-shaped pressure edge of the inner support plate is located above the inner edge plate, and the flat plate hanging edge is located below the inner edge plate; then install the corner formwork with bolts on the top and bottom of the front panel and the rear formwork; finally, fix and install the side formwork on both sides of the front panel and the rear formwork. Before pouring, first hoist the lifting ears on the upper part of the front and rear formwork, hoist the entire formwork to the predetermined pouring position, and after the formwork is positioned, press down the inner support plate to provide internal support for the middle of the front and rear formwork.

[0039] When demoulding, first remove the corner template at the bottom of the front panel, and then remove the template bolts on the side template connecting plate, and then lift the inner support plug plate. The flat hanging edge on the inner support plug plate cooperates with the hanging surface of the inner edge plate to lift the front template and the rear template. During the lifting process, the arc-shaped pressure edge is separated from the inclined supporting slope on the upper part of the inner edge plate, thereby withdrawing the internal support of the front template and the rear template. As the inner support plug plate is lifted, the front template and the rear template are lifted out of the cast water hole; finally, remove the two side templates that have lost the internal support of the front and rear templates, and the demoulding of the entire template is completed.

[0040] It should be noted that after the water outlet is cast, the corner formwork at the bottom of the front formwork needs to be removed in the water delivery corridor below the water outlet.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
