Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a waterproof layer protection structure based on cement blanket and a construction method. Background Art

[0002] Most common waterproof materials are flexible coils, which are easily damaged by external forces and lose their waterproof effect. In order to prevent the waterproof layer from being damaged by physical forces and extend the service life of the waterproof layer, a waterproof protective layer is often added on top of the waterproof layer. Common traditional waterproof protective layer methods include cement mortar protective layer, block surface protective layer, and fine stone concrete protective layer. Common waterproof protective layer methods are complicated, inconvenient to construct, and the finished product effect is overly dependent on the construction level of the workers. Summary of the invention

[0003] The present invention constructs a cement blanket on the surface of the waterproof layer. Compared with the traditional protective layer, only the cement blanket needs to be laid, which is convenient to construct, low in cost, green and environmentally friendly, and can be covered on the surface of objects of any shape and size, and is flexible and convenient to use.

[0007] S3. Evenly spray clean water on the cement blanket layer to solidify the cement blanket layer.

[0008] A further improvement of the present invention is that the reinforcement member is an anchor bolt, which includes a nut and an anchor end away from the nut. When constructing the anchor bolt, the anchor end is passed through the cement blanket layer and the waterproof layer and anchored in the existing structure, and the nut is pressed against the upper surface of the cement blanket layer.

[0009] A further improvement of the present invention is that the cement blanket layer comprises at least two cement blankets spliced ​​to each other, and after the reinforcement is constructed and before the step S3 is performed, two adjacent cement blankets are overlapped with each other using U-shaped nails.
