Abstract

The utility model discloses a flexible fastening hoop for a prestressed concrete water conveying pipe. The utility model is suitable for the water leakage first aid repair use of the bearing insertion opening of the prestressed concrete water conveying pipe of the water conveying and the water supply industries. The utility model has the structure that a bearing opening fastening hoop is flexibly connected with the insertion opening fastening hoop by screw bolts. The utility model has the advantages that the utility model can be repair and work at first time when the water flows, the leakage blocking construction period is short, the cost is low, and the utility model is ensured to conform to the flexible interface requirement of the deformation resistance and the antivibration of the original design. The technique has extensive application value in the water conveying and the water supply industries.

Description

The flexible anchor ear of Core type prestressed concrete pipe for water

The utility model has related to the flexible anchor ear of a kind of Core type prestressed concrete pipe for water, it is characterized in that rubber pad (4) being installed at Core type prestressed concrete pipe for water bellmouth (6) and Core type prestressed concrete pipe for water socket (1) pipe end, and (6) with bellmouth steel anchor ear (5) and the socket steel anchor ear (2) that is connected with bolt (8) (9) is installed, the special-shaped rubber cushion of installation between the front end of socket anchor ear (2) and Core type prestressed concrete pipe for water (6) tube head end face above (1) respectively.The flexible anchor ear feature of this Core type prestressed concrete pipe for water is: described bellmouth steel anchor ear (5) and socket steel anchor ear (2) are respectively semicircle

It belongs to water supply system, more be applicable to the repairing leak stopping of leaking of Core type prestressed concrete pipe for water bell and spigot position, defeated, water supply industry, it all is long-distance pipe, it is many that pipe gives interface quantity, it is the whole pipe weakest part, it also is the pipeline position of easy percolating water, in case when the generation feedwater piping leaks, be the back repairing of cutting off the water, during the leak stopping of bell and spigot position, reinforce the asbestos filleting with steel plate hoop and pound mouth, the outer steel bar concrete reinforcement of beating, or in managing, use the steel packing, spunyarn, asbestos cement is pounded mouth, and these method maintenances cause cost height, constructional difficulties in the winter time later.

In order to overcome former repairing blocking construction technical disadvantages, relate to a kind ofly be connected fastening with bolt with socket steel anchor ear by bellmouth steel anchor ear order of the present utility model, the liner flexible rubber material, thus realize failing, supply water to leak and rush to repair a kind of like this pipe fitting equipment of construction of not cutting off the water.

The purpose of this utility model is achieved through the following technical measures the flexible anchor ear of a kind of Core type prestressed concrete pipe for water, it is characterized in that rubber pad being installed respectively at concrete water transmission pipe bell and spigot end face, and on rubber pad, install respectively with bolted bellmouth anchor ear and socket anchor ear, special-shaped rubber cushion is installed between socket pipe front end and socket anchor ear.Bellmouth anchor ear and socket anchor ear are respectively half garden shape.The utility model advantage is band water repairing operation under normal water flowing condition, and the outside does not need Baogang's reinforced concrete again, guaranteed that former design is to the antidetonation of whole piece pipeline, the flexible interface requirement of resistance to deformation, thereby shortened the duration, reduced cost, and the utility model is not subjected to season and climatic effect when construction.
