Bore wider range of steel faucet concrete pipe is used also comparatively extensively, and along with country greatly develops infrastructure, water delivery gas pipeline demand increases greatly, especially the application of large-sized steel faucet concrete pipe.The two ends that the structure of present steel faucet concrete pipe is mainly concrete tube body install steel bellmouth and steel socket respectively, though it is better that this steel faucet concrete pipe connects sealability by O-ring seal, but find that through the long-time hydrostatic test there are the following problems: in the bulge test of steel faucet concrete pipe, when being added to certain pressure, water can ooze out along concrete and the slit that steel bellmouth or steel socket adhere to, through analysis of experiments, this seepage will influence the sealing and the pressure of supply water of whole pipeline.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of hinder leakage property strong, make simple, shorten the production time, can effectively strengthen the pipeline overall tightness, ensure the leakproof seal shaped steel system faucet concrete pipe of pressure of supply water.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of leakproof seal shaped steel system faucet concrete pipe, two ends at concrete tube body are fixed with bellmouth steel loop and socket steel ring respectively, wherein: bellmouth water blocking ring and socket water blocking ring are equipped with in the radial point solid welding on the bellmouth steel loop and/or on socket steel ring, gap between bellmouth water blocking ring and the bellmouth steel loop is packaged with waterproof gasket cement, gap between socket water blocking ring and the socket steel ring is packaged with waterproof gasket cement, and bellmouth water blocking ring and socket water blocking ring are packed on concrete pipe interior the bellmouth steel loop and socket steel ring respectively.

And the bellmouth water blocking ring spot welding that institute's spot welding installs on the described bellmouth steel loop is packed on the inwall and/or outer wall of bellmouth steel loop, and its quantity is N, 1≤N≤8.

And the socket water blocking ring spot welding that institute's spot welding installs on the described socket steel ring is packed on the inwall and/or outer wall of socket steel ring, and its quantity is M, 1≤M≤8.

And, the coaxial Framework Of Steel Reinforcement that is embedded with in the described concrete tube body, bellmouth steel loop and socket steel ring are packed in the two ends of Framework Of Steel Reinforcement respectively.

And the cross section of described bellmouth water blocking ring and socket water blocking ring is rectangular, circle or T shape.

Advantage of the present utility model and beneficial effect are:

1, this leakproof seal shaped steel system faucet concrete pipe is distinguished radially spot welding installation water blocking ring on bellmouth steel loop and/or socket steel ring, squeeze into waterproof gasket cement in the slit between bellmouth steel loop and socket steel ring and water blocking ring, this water blocking ring is arranged on concrete tube body interior the bellmouth steel loop and socket steel ring.The design of this kind water blocking ring can effectively reduce the water leakage ratio that steel bellmouth and steel socket and concrete adhere to the gap, effectively stops oozing out of water, has strengthened the Watertightness of steel faucet concrete pipe, has improved the barrier properties of whole concrete pipelines.

2, the quantity of the water blocking ring that installs on the bellmouth steel loop of this leakproof seal shaped steel system faucet concrete pipe is N, the span of N is 1≤N≤8, the quantity of the water blocking ring that installs on the socket steel ring is M, the span of M is 1≤M≤8, can be according to requirement of engineering, appropriate design water blocking ring quantity, and O-ring seal is installed, strengthen the sealability of whole pipeline.

3, on the radially coaxial outer wall or inwall that is packed in bellmouth steel loop and socket steel ring of this leakproof seal shaped steel system faucet concrete pipe water blocking ring, perhaps on the simultaneously radially coaxial outer wall and inwall that is packed in bellmouth steel loop and socket steel ring of water blocking ring, the cross section of water blocking ring is rectangular, circle or T shape, can effectively stop water to prolong the slit and ooze out.

4, structure resistance leakage property of the present utility model is strong, makes simply, shortens the production time, is a kind of leakproof seal shaped steel system faucet concrete pipe that can effectively strengthen the pipeline overall tightness, ensure pressure of supply water.
