[0014] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application.

[0015] The embodiment includes a rectangular steel formwork 1, which is a thin steel plate made of stainless steel and can be bent into a cylinder. The thickness of the rectangular steel formwork 1 is preferably 0.2-0.8 mm. A plurality of locking holes 2 are arranged on the opposite side edges of the rectangular steel formwork 1. The locking holes 2 are selected as rectangular holes, so that the side edges of the rectangular steel formwork 1 are in a grid shape. The rectangular steel formwork 1 can be rolled into a cylinder along the direction of the locking holes 2. The diameter of the rolled cylinder can be adjusted by changing the width of the overlapping side edges of the rectangular steel formwork 1. After the rectangular steel formwork 1 is rolled into a cylinder, the rolled cylinder can be fixed by inserting bolts 3 through the overlapping locking holes 2. The rolled cylinder is provided with bolts 3 on both sides. The length of the rolled cylinder of the rectangular steel formwork 1 is greater than the thickness of the structure wall, that is, the ends of the rectangular steel formwork 1 extend out of the wall.

[0016] The embodiment also includes a cylindrical air bag 4, which is placed in the cylinder rolled by the rectangular steel formwork 1 and used for sealing the inside of the rectangular steel formwork 1 and supporting the rectangular steel formwork 1. The length of the air bag 4 is also slightly greater than the thickness of the structure wall, and the end faces of the front and rear ends of the air bag 4 extend out of the ends of the wall. An air hole 5 is arranged on the front end face of the air bag 4, which is used for inflating and deflating the air bag 4.

[0017] During construction, first, the reserved hole on the structure wall is positioned, a hole is opened on the formwork of the structure wall, and a release agent is brushed on the outer surface of the rectangular steel formwork 1. Then, the rectangular steel formwork 1 is rolled into a cylinder and placed in the opened hole. The rectangular steel formwork 1 passes through the holes of the front and rear wall formworks. The diameter of the cylinder rolled by the rectangular steel formwork 1 is adjusted according to the size of the hole, so that the diameter of the cylinder rolled by the rectangular steel formwork 1 is consistent with the size of the hole. Then, the bolts 3 are screwed into the overlapping locking holes 2 to fix the rolled cylinder. The air bag 4 is placed in the cylinder rolled by the rectangular steel formwork 1, inflated through the air hole 5 until the air bag 4 tightly adheres to the inner surface of the rectangular steel formwork 1, and then the concrete is poured. After the wall formwork is removed, the air bag 4 is deflated through the air hole 5 and taken out. The bolts 3 are unscrewed. While the rectangular steel formwork 1 is shaken gently, the diameter of the cylinder rolled by the rectangular steel formwork 1 is reduced, and the rectangular steel formwork 1 is taken out. The reserved hole is formed in the structure wall, and the rectangular steel formwork 1 and the air bag 4 can be reused.

[0018] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit them; those skilled in the art should understand that they can still modify the technical solutions recorded in the above examples, or make equivalent replacements for some technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
