Abstract
The utility model discloses a kind of concrete bell-and-spigot pipes of mud jacking sealing, including public affairs pipe and main pipe, the end of public affairs pipe and main pipe is respectively provided with socket joint section, and public affairs are managed and the socket joint section of main pipe is respectively provided with mutual corresponding indent circumferential groove, and the socket joint section of main pipe also has the injected hole communicated with indent circumferential groove.The joint of public affairs pipe and main pipe is additionally provided with sealing outer press ring.The utility model in bell and spigot joint by setting indent circumferential direction to contain stock tank, after being installed in place, public affairs pipe and main pipe socket joint section on indent circumferential groove pairing cyclization to contain stock tank, then it is concaved outside pipe by injected hole and circumferential contains stock tank pressure injection slurry, sealing ring is formed after grout cures, seal for pipe joints is completed, significantly improves sealing effect.The seal form of the utility model adapts to slight displacement and the deformation at pipe joint, reduces to the rigidity of tube body sub-layer and laterally by the requirement of crowded balance.
Description
Technical field
The utility model is related to draining field, particularly for a kind of sealing of mud jacking of the sealing technique of plug-in adapted concrete pipe
Concrete bell-and-spigot pipe.
Background technology
In drainage system, concrete bell-and-spigot pipe is widely used, but load stiffness layer is inadequate due under, and pipeline laterally squeezes,
There is pipe joint displacement, disengage, cause seal for pipe joints inadequate, lead to percolating water.
Utility model content
The purpose of this utility model is to provide a kind of concrete bell-and-spigot pipe of mud jacking sealing, by bell and spigot joint pressure injection elasticity
Slurry improves joint sealing performance.
This realization above-mentioned purpose, the technical solution adopted in the utility model are：A kind of concrete bell-and-spigot pipe of mud jacking sealing, including
Public affairs are managed and main pipe, and the end of public affairs pipe and main pipe is respectively provided with socket joint section, and public affairs are managed and the socket joint section of main pipe is respectively provided with and corresponds
Indent circumferential groove, the socket joint section of main pipe also has the injected hole communicated with indent circumferential groove.
Preferably, the joint of the public pipe and main pipe is additionally provided with sealing outer press ring.
Preferably, the socket joint section of the public pipe and main pipe is threaded.
Preferably, the circumferential groove is multiple circular ring slots.
Preferably, the circumferential groove is spiral annular groove.
Due to taking above technical scheme, the utility model has the advantages that：
（1）By indent circumferential direction being set to contain stock tank in bell and spigot joint, after being installed in place, on public affairs pipe and main pipe socket joint section
Indent circumferential groove pairing cyclization to stock tank is contained, then outside pipe by injected hole concave it is circumferential contain stock tank pressure injection slurry, starching
Sealing ring is formed after liquid solidification, seal for pipe joints is completed, significantly improves sealing effect.
（2）The seal form of the utility model adapts to slight displacement and the deformation at pipe joint, the bullet of press mortar
Property performance adapt to micro-strain and lateral displacement between pipe, so as to ensure lasting seals, reduce to the rigidity of tube body sub-layer and
Laterally by the requirement of crowded balance.
In the following, the utility model technical characteristic is further described with reference to the drawings and the specific embodiments.
