Description

{non welding type installation structure of non water blockage valve room}

The present invention relates to a non-welding type non-stage water valve chamber installation structure, and more particularly, to a pipe in which fluid (water) flows, such as a water supply pipe, a water supply pipe, an industrial cold/hot water pipe, a sewage pipe, and the same diameter or small diameter. When connecting the branch pipe of to ensure worker safety, improve work efficiency, prevent inconvenience such as water outage during maintenance such as replacement of old pipes, and shorten work time to prevent inconveniences such as traffic control It relates to a non-welding type non-stage number valve chamber installation structure that can do this, and can also reduce the overall construction cost.

In general, the non-stage water method refers to a method of connecting a branch pipe of the same diameter or smaller diameter with the main pipe (supply and drainage pipe, etc.) The material and diameter of the organ will also vary.

In the normal non-single construction method, a stylus pipe or R-flange pipe is attached to the main pipe in a water-through state by screw assembly and welding, and then the branching point of the main pipe is drilled using a perforator.

That is, when the main pipe such as a water supply pipe is a cast iron pipe, an armature pipe is attached, and in the case of a steel pipe, the R-flange pipe is joined by welding to perform perforation.

For example, if the main pipe is a cast iron pipe, a branching part is formed by attaching the armature pipe in the above method, and then attaching a drain valve (gate valve) to the branch part in an open state, and a cutter of a perforator is attached to the main pipe in the branch pipe. After drilling is performed by inserting the cutter, the drain valve is shut off in a state in which the cutter is retracted, and then the drilling operation is completed by separating the drilling machine.

Therefore, this continuous water method can complete branching work while maintaining and operating any type of piping line, such as industrial water, cooling water, hot water, air, or oil line, without blocking the flow of fluid. It is possible to extend the connection line connecting the branch pipe to the main building and easily install facilities such as a fire hydrant at a desired location.

First, by connecting the branch pipe to the main building in the water flow state, there is no inconvenience and inconvenience caused by the water supply.

Second, while the conventional single-stage method requires a long time, the non-destructive method has some differences depending on the conditions, but since all work can be completed in about an hour, it is much more economical because the work speed is faster, and it is not There is no fear of causing communication problems.

Third, in the single-piece method, by applying striking vibration to the main pipe and branch pipes using tools such as chisels and hammers, deformation and cracking of these pipes may occur, which may cause water leakage, and rust may occur due to the lining in the pipe falling off. The continuous water method is very hygienic as no foreign substances are left in the pipe after the construction is completed.

Fourth, in the continuous construction method, any pipe can be constructed regardless of the diameter of the main building as long as the diameter is less than the same diameter, and the hole can be drilled at a desired angle in any direction 360° over the entire periphery of the main building. can also be easily performed.

On the other hand, an example of a structure of a non-stage valve chamber according to the prior art in which a joint in which a valve or a flow meter of a pipeline installed according to such a non-stage method is installed is protected from the outside is disclosed in Korean Patent Registration No. 10-0806134 (2008). Registration dated February 15, hereinafter referred to as 'Patent Document 1') and the like.

However, since the non-stage valve chamber according to the prior art must be installed by assembling and welding the heavy iron plate in an underground burial space by directly transporting it by manpower, if the iron plate is accidentally dropped during the transport process of the iron plate, the operator is buried underground. There is a problem that there is a risk of suffocation accidents such as being seriously injured in a space, easily exposed to welding gas, etc. while performing welding work in an enclosed space, and work fatigue of the operator may increase.

In addition, due to such a poor work environment, work efficiency is greatly reduced, and in most cases where work skill is not high, work time is delayed, and maintenance work such as replacement of old pipes is required, which causes great inconvenience to users. There is a problem that the traffic control of the road where the manhole sphere is exposed to the ground is also made for a relatively long time, and the overall construction cost can be greatly increased.
