Drainage pipeline

Abstract

The invention discloses a drainage pipeline. The drainage pipeline comprises a pipeline body. The top of the pipeline body is provided with an opening. Two partition boards are arranged in the middleportion of the pipeline body. The opposite faces of the two partition boards make contact with each other for sealing. The other ends of the two partition boards are integrally connected with the pipeline body. The two partition boards cut off a drainage channel in the middle of the pipeline body. A bottom drainage cavity is formed below the two partition boards. A clamping cavity is formed at theupper ends of the partition boards. An intermediate pipe is arranged in the clamping cavity. The middle of the intermediate pipe is provided with an independent drainage channel. The drainage pipeline can realize respective cavity discharge of two kinds of liquid simultaneously. The whole pipeline can be opened in the shearing process, water in the pipeline is discharged to give an effective warning. When shear force is large, the intermediate pipe can be pressed into the bottom drainage cavity below the partition boards to be protected. The drainage pipeline has good buffering performance and protective performance, also has the good warning effect and achieves the effect of high-efficiency liquid discharge.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to a drainage pipeline. Background technique [0002] Pipelines are used to transport various liquids, such as water, waste liquids or chemical liquids, etc. Liquids can also be divided into hot and cold, and hot liquids need to be cooled after discharge, while cold liquids are normally discharged through pipes. If the hot and cold liquids are discharged at the same time, not only the discharge efficiency can be improved, but also the cold liquid can be used to cool the hot liquid during the transmission process, thus reducing the later cooling time; [0003] Furthermore, pipelines are generally buried, and these buried pipelines are particularly susceptible to damage due to external force shearing. The pipelines in the prior art are generally a closed structure, so that the pipeline ruptures after the external force is sheared. , the internal liquid keeps gushing out, and the seal cannot ...

[0003] Furthermore, pipelines are generally buried, and these buried pipelines are particularly susceptible to damage due to external force shearing. The pipelines in the prior art are generally a closed structure, so that the pipeline ruptures after the external force is sheared. , the internal liquid keeps gushing out, and the seal cannot be restored after the force is removed, and the important pipeline will cause serious environmental damage or economic loss after being cut, and the safety performance of the buried pipeline is poor
