In order to achieve the above purpose, the utility model is realized by the following technical scheme: the utility model provides a reinforcement type concrete pipe, includes the concrete pipe body, the one end of concrete pipe body is equipped with sleeve and the other end is equipped with the inner tube, the movable cartridge of inner tube is in the sleeve, the outer wall of inner tube with telescopic inner wall sliding contact, the outer wall of inner tube is equipped with annular draw-in groove, be equipped with two pairs of spouts in the sleeve, two pairs all movable cartridge has the slider in the spout, two pairs the one end of slider all is connected with the arc slat, two pairs the equal sliding cartridge of arc slat is in the annular draw-in groove.

Preferably, a pair of fastening curved plates is placed on the outer wall surface of the sleeve.

Preferably, a fastening bolt is screwed between the pair of fastening arc plates.

Preferably, a leakage-proof layer is arranged in the concrete pipe body.

Preferably, an anti-corrosion layer is arranged in the anti-leakage layer.

Preferably, the reinforcing layer is arranged outside the concrete pipe body.

Advantageous effects

The utility model provides a reinforced concrete pipe, which is designed with a structure for increasing connection stability, when two concrete pipe bodies are required to be connected, an inner pipe is inserted into a sleeve, a sliding block slides in a sliding groove, an arc-shaped slat is clamped into an annular clamping groove to be fixed, meanwhile, two fastening arc-shaped plates are placed on the outer wall surface of the joint of the two concrete pipe bodies, the positions of the two pairs of sliding blocks are fixed by the two fastening arc-shaped plates, and the two concrete pipe bodies can be connected more stably by screwing and fixing through fastening bolts. The device effectively increases the stability of connection between two concrete pipes, prevents that two adjacent pipe fittings from taking place the slippage dislocation, avoids appearing the condition that liquid leaked.
