Description
Technical Field
The invention relates to a pipeline connecting technology, in particular to a flexible connecting method for a cement concrete culvert pipe.
Background
With the development of new materials and new technologies, cement concrete materials and pipeline application are gradually limited, however, in the aspect of ultra-large-diameter pipelines, no good new material and new technical means can perfectly replace cement concrete pipelines, particularly, the specification of a water taking and discharging pipeline of a nuclear power external equipment cooling system generally exceeds 6 meters in diameter, for example, a pipe made of a high-quality plastic material cannot reach the specification, so that a cement concrete culvert pipe still exists in the field for a long time, the culvert pipe is completely a rigid pipeline, the anti-settling performance cannot be realized by a traditional connection mode, the connection point is greatly influenced by small change of geology, light leakage, severe even complete fracture and huge damage are caused, and the development of a connection means with excellent flexibility is urgently needed.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a flexible connecting method of a cement concrete culvert pipe, which has excellent hoop rigidity and sedimentation leakage resistance on the premise of a connecting means with excellent toughness.
In order to achieve the purpose, the technical scheme of the invention is as follows: a flexible connection method for a cement concrete culvert pipe comprises the following steps: firstly arrange the high density polyethylene C shape ring in the intraoral recess of cement concrete culvert pipe socket that will connect, arrange rubber seal in the rubber ring standing groove on the socket at high density polyethylene structure wall connecting piece both ends respectively, then insert the socket at high density polyethylene structure wall connecting piece both ends respectively in the cement concrete culvert pipe socket that will connect, afterwards, the socket struts the high density polyethylene C shape ring, and finally, the circular telegram heats the high density polyethylene C shape ring, the socket and the butt fusion of high density polyethylene C shape ring at high density polyethylene structure wall connecting piece both ends are in the same place, the completion is connected.
The high-density polyethylene C-shaped ring is provided with metal electric fuses, and the metal electric fuses are distributed on the high-density polyethylene C-shaped ring in a zigzag manner.
The end part of the cement concrete culvert pipe is provided with a bellmouth, and a groove is arranged in the bellmouth.
The high-density polyethylene structure wall connecting piece both ends be equipped with the socket, be equipped with the rubber ring standing groove on the socket.
The invention has the outstanding advantages that: the high-density polyethylene winding structure wall connecting piece has excellent toughness, achieves anti-settling property, can be completely fused with a high-density polyethylene C-shaped ring at a melting temperature, achieves the possibility of preventing pipeline connection disconnection caused by a settling process after fusion, can meet the requirement of various annular rigidity in a freely designed structural wall form, selects a high-quality rubber ring to achieve complete sealing, and fully solves the defect that the cement concrete culvert pipe is not resistant to settling when being connected.
