Description
Technical Field
A reinforced concrete rabbet pipe for preventing water leakage of a joint is used for urban drainage pipelines and belongs to the technical field of rabbet pipes.
Background
Along with the development of cities, the environment quality is more and more emphasized, open ditch and hidden ditch type drainage modes are gradually eliminated due to certain pollution to the environment and influence on the attractiveness of the cities, and reinforced concrete drainage pipes are suitable for removing rainwater, sewage, water diversion, farmland irrigation and drainage and irrigation and other gravity flow pipelines in industrial and mining places and towns, are buried underground and do not pollute the environment, have the advantages of large external pressure bearing capacity, good durability, convenience in installation, low cost and the like, and are widely applied to drainage projects of cities, highways and the like.
At present, more than 90% of global urban drainage pipelines are made of reinforced concrete, and the joint modes mainly comprise 3 types of plain mouths, tongue-and-groove mouths (steel bellmouths) and bell and spigot mouths. The concrete pipeline can be made into a pressureless pipe, a low-pressure pipe, a prestressed pipe and the like according to different purposes, and the laying mode comprises open cut laying, trenchless top pipe laying and the like. The safety of the pipeline depends greatly on the quality of the joint during laying, and the qualified pipeline joint has the advantages of high strength, impermeability, certain elasticity and resistance to corrosion or erosion of sewage or ground drainage.
Because the urban pipe network is characterized by long distance, multiple pipe diameters, adaptability to multiple systems (rainwater, sewage, special water and ecological water), large change of environmental and geological conditions and stress concentration at the joint of the pipelines, most of the existing pipelines adopt rabbet pipes which are connected in a mode that a pipe end tenon is in joggle joint with a pipe end mortise of another pipe, and the connection mode can transfer loads between pipe fittings and increase the sealing performance. Generally, a sliding rubber ring is adopted for sealing and stopping water. But the tongue-and-groove pipe still has the following technical problems:
when a long-distance aqueous medium is conveyed, the rabbet pipes are displaced due to the shear force of the inner walls of the pipes, the creeping of pipe joints and the change of geological environment, and natural disasters such as earthquake and the like, so that the acting forces generated by axial and radial displacement are concentrated at the joint parts of the rabbet pipes, thereby easily causing water leakage at the joint parts;
secondly, once the seam part of the rabbet pipe is easy to go wrong, the problems that the service life of the urban pipe network is shortened and the maintenance cost of the urban road is increased are caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prevent reinforced concrete rabbet pipe that interface leaked, the tenon and the tongue-and-groove of solving two adjacent rabbet pipes among the prior art are connected the cooperation back, easily cause the seam position to leak, the problem that the interface leaked promptly.
In order to realize the purpose, the utility model discloses a technical scheme be:
a reinforced concrete rabbet pipe capable of preventing water leakage of a joint comprises a pipe body, wherein a tenon is arranged at one end of the pipe body, a mortise is arranged at the other end of the pipe body, a first annular groove for arranging a gasket and a strip-shaped groove for arranging the gasket are formed in the outer side surface of the tenon, one end of the strip-shaped groove is positioned at the end part and is opened, and the other end of the strip-shaped groove is communicated with the first annular groove;
