Abstract
The utility model discloses a steel ring joint for a reinforced concrete water discharge pipe. The surface of a ring body of a steel ring is provided with a plurality of grooves towards the inner side, so the cross section of the ring body of the steel ring is in a multi-continuous-S bending shape. The steel ring joint has the advantages that the surface of the ring body of the steel ring is provided with the grooves, rubber rings and rubber sealing rings which can expand when meeting water can be placed into the grooves, and the goal of realizing the waterproof effect on a gap between the steel ring and a cement pipe can be reached; a cement pipe body can be anchored by a second groove, so the steel ring does not need to be welded with a reinforcing mesh in a cement pipe body, the manufacture work procedure of the reinforced concrete water discharge pipe is reduced, simultaneously, the danger of steel ring desoldering falling in the pipeline construction can be greatly reduced, simultaneously, the manufacture cost can also be greatly reduced, and the internal space in the pipe body is also larger than the internal space formed by adopting the built-in steel bar fixation.
Description
Technical field
The utility model relates to a kind of joint, particularly a kind of reinforced concrete sewer pipe steel ring joint that is used for sewer.
Background technology
Drain pipe is a kind of pipeline that is used for effluent sewerage or rainwater, is used to collect and discharge the daily life sewage and the industrial industrial wastewater that produces that the city produces, and existing sewer pipe mainly is the gravity sewers system; Its sewer pipe is tilted to down, and wherein the mobile of sewage is to rely on gravity, in the pressure sewerage system, uses overvoltage to carry sewage to pass through small-bore sewer pipe; Advantage is simple and convenient, but also has the problem, the particularly junction surface of two water pipes of damaging easily, leaking; Because corrosion and expanding with heat and contract with cold; Thereby cause the junction distortion and the slit occurs, and cause leakage, and cause very big destruction to living environment.
The scheme that solves at present generally is to be employed in that steel ring is inner to be increased supporter or coat other materials at the junction surface, and its advantage is durable, but weak point to be process loaded down with trivial details causes dismounting inconvenience, its use cost also significantly increases in addition.
Summary of the invention
The purpose of the utility model is, a kind of reinforced concrete sewer pipe steel ring joint is provided, the application life that can reduce the dangerous of pipeline junction generation seepage greatly and improve pipeline.
A kind of reinforced concrete sewer pipe steel ring joint, there are a plurality of grooves to the inside on said steel ring circle body surface, makes that steel ring circle body cross section is a plurality of continuous S bendings.
In addition, there is to the inside a crimping at the steel ring two ends, and said steel ring circle body cross section can be three continuous S bendings, and three grooves on steel ring surface are for being arranged in parallel.
Said three groove parts are effective, and first groove is embedded in the rubber ring of water-swellable, reach the waterproof purpose in slit between steel ring and the pipe of cement; Second groove plays the effect of being fixed in the cement body, and the steel mesh reinforcement of pipe of cement need not to weld with steel ring; Lay fixedly rubber seal when the 3rd groove is the pipeline construction installation, play two bodys and connect waterproof actions.
The said sewer steel ring of the utility model union, its advantage is: fluted rubber ring and the rubber seal of inserting water-swellable in steel ring circle body surface, can play the waterproof purpose in slit between steel ring and the pipe of cement; Second groove can be anchored in the cement body; Like this steel ring need not again with the cement body in the steel mesh reinforcement welding; Can reduce the danger that the steel ring sealing-off comes off in the pipeline construction greatly when reducing the reinforced concrete sewer pipe production process; Also can reduce manufacturing cost greatly in addition, the inner space of body is also big than what adopt built-in reinforcing bar to fix.
Description of drawings
Fig. 1 is the structural representation of sewer steel ring union;
Fig. 2 is the schematic cross-section of sewer steel ring union.
The specific embodiment
Through the specific embodiment the utility model is described below, but is not limited to this.
A kind of sewer steel ring union is characterized in that: there are a plurality of grooves 2 to the inside on said steel ring 1 circle body surface, makes that steel ring circle body cross section is a plurality of continuous S bendings.
In addition, there is to the inside a crimping 3 at the steel ring two ends, and said steel ring 1 circle body cross section can be three continuous S bendings, and three grooves on steel ring 1 surface are for being arranged in parallel.
Said steel ring joint; Can be used as the usefulness of the connector of two pipe of cement sewers; Compare existing steel ring; Can be used for filling elastic caoutchouc and the groove that plays muscle owing to increase, can increase the rigidity of steel ring like this and fully avoid the not tight problem of cushion rubber screens, and to stop the seepage phenomenon that causes because of it between body.
Claims (3)
