The invention relates to a self-waterproof casing pipe convenient to install. The self-waterproof pipe convenient to install is mainly used for waterproof use of pipelines penetrating water pool walls in the field of building engineering and can also be used for waterproof use of pipelines penetrating roofs or building surfaces or wall surfaces. The self-waterproof casing pipe convenient to install is mainly composed of a steel casing pipe, a steel water stop ring, a waterproof rubber ring and a waterproof cover. According to the main work principle and the installation method, when concrete is poured to the wall of a water pool, the steel casing pipe and the steel water stop ring are embedded in concrete, when the concrete reaches certain strength, the pipeline needed for penetrating penetrates the steel casing pipe, then the waterproof rubber ring is arranged on the pipeline in a sleeving manner from top to bottom, the conical face of the waterproof rubber ring is tightly attached to the oblique face of the steel casing pipe, then the pipeline penetrates a hole in the waterproof cover from top to bottom, the waterproof cover is screwed, the upper surface of the waterproof rubber ring is pressed step by step through the waterproof cover, the waterproof rubber ring moves downwards step by step, the conical face of the waterproof rubber ring and the oblique face of the steel casing pipe are pressed tightly, and installation work is finished.
