Safe pipe body stacking type dam device

The invention relates to a cystic pipe body stacking type dam device. The cystic pipe body stacking type dam device comprises outer cystic pipes (1), a connecting body (2), a fixing device (3), inner cystic pipes (4), anchor piles (6), a fixing rope (8), a pressure sensor (10), a U-shaped pipe (11) and a controller (12). Multiple outer cystic pipes (1) are mutually overlapped according to a certain rule, the outer walls of the outer cystic pipes (1) are tangent and mutually extrude, the outer cystic pipes are fixed in an annular structure of the fixing device and are fixed on a dam foundation through anchor piles of the fixing device (3), and inner cystic pipes are positioned in the outer cystic pipes in an overlapped manner and are mutually communicated through a connecting body with a water stop valve (9) and a pressure sensor (10). One end of a cystic body of each communicated inner cystic pipe is connected with a water inlet pipe and a pump body, and the pressure sensor is connected with the controller (12) through a wire. The device is low in manufacturing cost, light in weight, capable of being used repeatedly, high in installation speed, little in leakage, free of pollution, firm in dam structure and good in effect of resisting puncture and damage of sharp sundries.
