Description

Split construction pipe for main building and non-excavation pipe laying method using the same

The present invention relates to a split construction pipe for the main building to be applied to the water pipe, sewage pipe, waterway, electric power, communication, gas pipe and tunnel, and a non-excavated pipe laying method using the same.

In the conventional steel pipe indentation or propulsion applied to water pipes, sewer pipes, waterways and tunnels, the outer surface coating of steel pipes is damaged by friction with the ground, and primarily presses or injects tubular steel or concrete pipes of larger diameter than steel pipes. After propulsion, the main pipe including the steel pipe having a smaller diameter than the steel pipe or the concrete pipe is inserted into the inside of the steel pipe or the concrete pipe, and then press-fill the pipe by filling the gap space between the main pipe and the external indentation or propulsion steel pipe or concrete pipe with mortar. Alternatively, by pushing, the material cost of the external indentation or propulsion steel pipes or concrete pipes and the related construction costs are excessively consumed.

When the above-mentioned point is described in more detail, in the case of the conventional cylindrical steel pipe indentation or propulsion, in the case of the external indentation or propulsion steel pipe or concrete pipe, the gap space of the outer surface of the main pipe including the steel pipe is filled with mortar only in the construction process. As long as the stability is maintained, the use of expensive cylindrical steel pipes or concrete pipes of a conventional permanently stable structure is a kind of excessive planning or design, and consequently, excessive construction costs are required, resulting in cylindrical steel pipes or concrete pipes. As a result, the propulsion force gradually increased from the time of construction is accompanied, and even when propelling a long distance, the tip of the tubular steel or concrete pipe is damaged or the frictional force between the surrounding ground and the tubular steel or concrete pipe is Relatively increased by increasing Since the true distance is shortened, there was a problem that the workability is reduced.

In order to solve the problems of conventional steel pipe indentation or propulsion methods, the main pipe embedding temporary construction pipe and non-excavation pipe laying method using the same are structural in the process of constructing a cylindrical or concrete tube for external indentation or propulsion.
