Referring to fig. 1 to 2, the pipe branch connection structure in the embodiment of the present invention includes a first pipe 11 and a second pipe 12, and the first pipe 11 and the second pipe 12 may be pipes made of different materials, for example, in this embodiment, the first pipe 11 is a concrete pipe, and the second pipe 12 is a metal pipe. An opening is formed in the pipe wall of the first pipeline 11, specifically, a breaking surface boundary line is reserved on the pipe wall of the first pipeline 11 according to the size of the second pipeline 12, then the pipe wall of the first pipeline 11 is broken along the breaking surface boundary line to form an opening capable of being connected with the second pipeline 12 in a branch mode, and the second pipeline 12 is connected with the opening of the first pipeline 11 through a connecting structure. Further, one end of the second pipe 12 extends into the opening, and the second pipe 12 is clearance-fitted to the opening. The second pipeline 12 stretches into the opening and then is welded with the first steel plate 21, and due to the clearance fit between the second pipeline 12 and the opening, the second pipeline 12 can be conveniently stretched into the opening, and the second pipeline 12 can be conveniently welded with the first steel plate 21.
The connecting structure comprises a bolt 24 and a first steel plate 21, the first steel plate 21 is located on the inner wall of the opening, a first connecting port opposite to the opening is formed in the first steel plate 21, the second pipeline 12 is connected with the first connecting port, and therefore the second pipeline 12 can be communicated with the first pipeline 11 through the first connecting port. The first steel plate 21 is provided with a first connecting through hole, the pipe wall of the first pipeline 11 is provided with a second connecting through hole, the bolt 24 penetrates through the first connecting through hole and the second connecting through hole and then is fixed, and the elastic sealing layer 23 is arranged between the first steel plate 21 and the inner wall of the first pipeline 11. After the bolts 24 are fixed, the first steel plate 21 can be fixed relative to the first pipeline 11, and the first steel plate 21 and the second pipeline 12 can also co-extrude the sealing layer 23, so that the sealing layer 23 can prevent leakage. The sealing layer 23 may be a rubber cushion or the like. Further, connection structure still includes second steel sheet 22, and second steel sheet 22 is equipped with the second connector relative with the opening, and second steel sheet 22 is located the open-ended outer wall, is equipped with third connect the through-hole on the second steel sheet 22, and bolt 24 is fixed after running through first connect the through-hole, second connect the through-hole and third connect the through-hole. The bolt 24 is fixed through the nut after penetrating through the first connecting through hole, the second connecting through hole and the third connecting through hole, the nut is abutted to the second steel plate 22, the second steel plate 22 is arranged to avoid the nut from being directly pressed on the first pipeline 11, and therefore the force of the nut on the first pipeline 11 is more uniform. Optionally, the number of bolts 24 is plural, and the plural bolts 24 are arranged at intervals around the opening.
Further, the connecting structure further comprises a concrete member 40, and the concrete member 40 connects the outer wall of the opening and the pipe wall of the second pipe 12. The concrete member 40 serves to connect the first pipe 11 and the second pipe 12 and to slow down or even block leakage when leakage occurs at the branch joint of the first pipe 11 and the second pipe 12. The outer wall of the second pipeline is provided with a water stop ring 50, and the water stop ring 50 is fixed in the concrete member 40 so as to prevent liquid leaked at the branch joint of the first pipeline 11 and the second pipeline 12 from leaking all the way along the second pipeline 12 and reduce leakage. In addition to the above embodiment, the connection structure further includes a first reinforcing bar 31 and a second reinforcing bar 32 having a ring shape, an end of the first reinforcing bar 31 is connected to the bolt 24, and when the number of bolts 24 is two or more, the number of first reinforcing bars 31 is also two or more, and each first reinforcing bar 31 is connected to each bolt 24. The second reinforcing bars 32 are wound around and fixed to the outer sides of all the first reinforcing bars 31, thereby fixing the relative positions of the first reinforcing bars 31 and preventing the first reinforcing bars 31 from being deformed or positionally displaced. After the concrete is poured to form the concrete member 40, the first reinforcing bars 31 and the second reinforcing bars 32 are fixed in the concrete member 40. Because one end of the first steel bar 31 is connected with the bolt 24 and fixed in the concrete member 40, the stability of the concrete member 40 is increased, the connection durability of the concrete member 40 and the opening is enhanced, and the anti-leakage performance is improved.
In some embodiments, the end of the second conduit 12 remote from the first conduit 11 is provided with a flange 51 to facilitate connection and communication with other conduits.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
