Embodiment Construction
[0028] The present invention will be further described below in combination with specific embodiments.
[0029] The invention is a self-sealing device for a drainage board, which consists of two parts: a sealing body 1 on the top of the drainage board and a water and air suction pipe 2 . Drain board board body 3 adopts conventional drain board, can be plastic drain board, also can be papery or other materials.
[0030] The length of the sealing body of the self-sealing device is about 50-500mm, and its specific size is determined by the properties of the surface soil in the reinforcement area. There is a connecting hole on the top or side of the self-sealing device. The diameter of the hole is about 16mm. The specific size can be determined comprehensively according to the pipe diameter of the suction and drainage connecting pipe system. The drain board can be directly connected to the drainage system through the suction pipe.
[0031] The sealing forming method of the self-...
