Wherein one casting reinforced one end positioned at the reinforcing bar interface section of ring, wherein another road ring is casting reinforced being connect positioned at the reinforcing bar
The other end of mouth section.
S30：Cast forms pipe of concrete 100 and reinforcing ring 300.
The connection method of the pipe connecting structure, after pipe of concrete 100 is connected with connecting pipe 200, attachment structure energy
Enough effectively reduce both sides at the pipe joint of pipe of concrete 100 and connecting pipe 200 due to material difference cause it is uneven heavy
Drop, makes to be less prone to drawing crack destruction at pipe joint so that at the pipe joint that pipe of concrete 100 overlaps with connecting pipe 200
With stronger resistance to overturning, and seal ring 400 is set on the outer wall of connection pipeline section 210, the path that water logging is oozed can be increased
Length, it is to avoid cause there are flowing out because connecting pipe 200 and the contact surface of pipe of concrete 100 bond bad, possess preferably
Sealing property；Additionally, reinforcing ring 300 is molded with pipe of concrete 100 using same method, the structural strength of reinforcing ring 300 is high, mixes
Solidifying soil pipe 100 and reinforcing ring 300 can be manufactured together, easy construction.
Further, the step S10 is concretely comprised the following steps：At least twice are welded on the outer wall of connection pipeline section 210 to stop
Water ring 400, wherein the seal ring 400 is welded in one end of the connection pipeline section 210 together, wherein seal ring described in another road
400 other ends for being welded in the connection pipeline section 210.Using said structure, on the one hand, at least twice seal ring 400 being capable of shape
Into at least two-stage waterproof construction, the infiltration path of current is effectively increased, it is to avoid because connecting pipe 200 and pipe of concrete 100 connect
Contacting surface bonds bad and causes there are flowing out, and reduces the possibility of attachment structure leak, it is ensured that have at pipe joint preferable
Sealing, especially in the case where hydraulic pressure is larger, can effectively ensure that connection position is equipped with preferable sealing, it is to avoid or reduce water
Seepage；On the other hand, one seal ring 400, the set location of seal ring 400 are respectively arranged at two ends with connection pipeline section 210
Set location with reinforcing ring 300 is corresponding, seal ring 400 and the mutual coordinated of structure of reinforcing ring 300, can further have
Effect ensures both possessed strong stability at pipe joint, but also with good sealing.
