[0002] At present, in the field of on-site building construction, waterproofing of basement outer walls is still carried out after the outer wall construction is completed and reaches a certain strength. This process is complex, and the construction time is long. In addition, the waterproofing material needs to be bonded after the concrete reaches the strength, which cannot guarantee 100% bonding of the material and the concrete surface, and the overall performance is poor.

However, in the above-mentioned document, the non-woven fabric is fixed on the outer wall formwork by a suction cup, and the non-woven fabric needs to be pressed on the suction cup, so that multiple convex ends are generated between the non-woven fabric and the outer wall formwork. When the two outer wall formworks are fixed by the tensioning bolts and press the cast-in-situ wall, the suction cup will cause holes in the cast-in-situ wall through the non-woven fabric.
