Operating platform for trenchless inversion liner of buried pipeline

Abstract

The invention discloses an operating platform for the trenchless inversion liner of a buried pipeline. The operating platform comprises a platform rack body with a frame structure and a portal hoisting rack extending upward along the middle of the platform rack body, wherein the hoisting rack is provided with a hoisting device controlled by a power source; and a liner introducing tube is arranged lengthwise under the hoisting rack and connected with the platform rack body through a lifting device. The invention has the advantages of compact and simple structure and perfect function; the hoisting and lifting devices are used to ensure that the liner material can be hoisted and turned over without the fit of a crane; a distribution pipe is used to adjust the quantity of water on the platform; traveling wheels are used without no crane or trailer for during moving or mobile drilling; a communication device is used to ensure that the underground operator and the ground operator can talk smoothly; and the compact structure ensures that the floor area of the device is only about 4m<2>, the mouth of a well is not needed to be trenched when the liner is turned over, and the integrity of the trenchless technology for repairing the buried pipeline can be ensured.

Description

technical field [0001] The invention relates to auxiliary equipment for repairing buried pipelines, in particular to an operation platform for the non-excavation turning inner lining of buried pipelines. Background technique [0002] With the development of modern industry, various types of buried pipelines are becoming more and more important in people's daily life and urban construction. A large number of gas pipelines and buried industrial pipelines will be damaged to varying degrees after being put into use for 15-20 years, and they have entered a period of high incidence of accidents, so the old pipelines must be repaired in a planned way. The old pipeline trenchless repair technology is a very economical online maintenance method that does not require excavation construction and makes full use of old pipe materials. Among them, the technology of repairing the pipeline by flipping the lining has been developed rapidly. It is considered to be the most convenient and eco...

Problems solved by technology

[0004] The above-mentioned repair technology can repair the overall lining of buried pipelines with a diameter of 100mm-3000mm. The length of one construction operation can reach about 500 meters depending on the pipe diameter and operating conditions. It is still in its infancy in our country, and there is no perfect operation platform in the current construction
