Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
As shown in fig. 1 and 2, the corrugated pipe quick connecting device for the precast concrete inspection well comprises a concrete pipe 1 and a corrugated pipe 2, wherein a connecting pipe 3 is arranged in the bottom of the concrete pipe 1, the connecting pipe 3 is fixedly connected with a steel reinforcement framework of the concrete pipe, a quick connecting joint 4 is arranged in the connecting pipe 3, and the quick connecting joint 4 is connected with the corrugated pipe 2; quick connect coupler 4 mainly comprises joint pipe 5, elastic sealing ring 6 and end cover 7, and 5 threaded connection of joint pipe are on connecting pipe 3, install elastic sealing ring 6 in the joint pipe 5, and 2 cartridge of bellows are in elastic sealing ring 6, and are provided with a plurality of protruding stupefied 8 of sealing on the elastic sealing ring 6, and protruding stupefied 8 of sealing is used for the card in the trough groove of bellows, and end cover 7 is still installed to the tip of joint pipe 5.
According to the utility model, the connecting pipe is preset in the concrete pipe, the inner wall of the connecting pipe is provided with threads, and the length of the connecting pipe is the same as the wall thickness of the concrete pipe. For some connecting pipes with larger calibers, the connecting pipes can be cut to form pipe sections with the radian identical to that of the concrete pipe. Then after the concrete pipe shaping, directly connect quick connect coupling on the connecting pipe, the outside installation elasticity sealing washer of bellows, then with bellows cartridge in quick connect coupling's the coupling pipe, elasticity sealing washer sets up and forms sealedly between coupling pipe and bellows. The elastic sealing ring is provided with a sealing convex edge for fixing on the corrugated pipe. The end cover is used for limiting the sealing ring and sealing the port.
