Culvert passing device for nodular cast iron pipe

Abstract

The invention relates to a culvert passing device for a nodular cast iron pipe. a plurality of towing wheels are fixedly arranged on the lower end of a towing wheel fixing plate; the left and right ends of the towing wheel fixing plate are respectively and fixedly connected with the lower ends of a left locking plate and a right locking plate detachably; the upper ends of the left and right locking plates are detachably fixed. The culvert passing device for the nodular cast iron pipe has a simple structure and can realize passing rapidly.

Description

technical field [0001] The invention relates to a device for passing through a culvert, in particular to a device for passing through a culvert whose diameter is not much different from that of a nodular cast iron pipe. Background technique [0002] In the installation and commissioning industry of ductile iron pipes, we often encounter the problem that pipelines need to cross roads or tall buildings. Usually, in municipal planning, reserved holes for pipeline installation are generally reserved. As time goes by, the society With the rapid development of the pipeline, the flow rate of the pipeline is getting larger and larger, and the diameter of the pipeline is also getting bigger and bigger. This often results in the situation that the reserved hole is slightly larger than the diameter of the pipeline, and people cannot go in for construction. If the road is dug, it will cause traffic congestion. The blockage will cause huge capital costs. If pipe jacking is used for insta...

[0002] In the installation and commissioning industry of ductile iron pipes, we often encounter the problem that pipelines need to cross roads or tall buildings. Usually, in municipal planning, reserved holes for pipeline installation are generally reserved. As time goes by, the society With the rapid development of the pipeline, the flow rate of the pipeline is getting larger and larger, and the diameter of the pipeline is also getting bigger and bigger. This often results in the situation that the reserved hole is slightly larger than the diameter of the pipeline, and people cannot go in for construction. If the road is dug, it will cause traffic congestion. Blocking and generating huge capital costs. If pipe jacking is used for installation, the capital cost will be very large, not to mention that ductile iron pipe jacking is not common in the market, which is a headache for all investors or Party A.
