Resin mixing pipe manufacturers talk about the application areas of jacking pipes

Resin-mixed pipe manufacturers discuss the application areas of pipe jacking.

Pipe jacking is made of various materials, including concrete, steel, and glass-filled pipes. However, the underlying principle remains the same: a working well is typically constructed vertically downward from the ground. Lubricant is then applied to the pipe, and the pipe is lowered into the ground using a hydraulic jack. The various processes differ in the method used to transport the excavated soil, rocks, and other debris from the pipe. These processes can be manual, hydraulic, or remote. Today, we'll discuss fiberglass-reinforced reinforced pipe jacking.

Fiberglass-reinforced reinforced pipe jacking is achieved by intermittently filling the pipe with sand according to a predetermined number of layers. A 300-800mm section of pure fiberglass is left on both sides of each pipe, partially reinforced with fiberglass fabric. Each pipe is then ground and cut using specially designed equipment. After trimming to the specified shape and size, it can be demolded. Therefore, fiberglass-reinforced pipe jacking utilizes a design and production process that integrates pure fiberglass with glass-filled reinforced pipes.

Fiberglass pipe jacking can cross roads, railways, and surface and underground structures. Due to its excellent corrosion resistance, lightweight, smooth interior, high flow capacity, and adaptability to geological conditions, it has become a common piping material used in pipeline network renovations in large and medium-sized cities. So, what specific applications are there? Let's take a look.

Fiberglass pipe jacking is typically used in the following situations:

1. Pipes crossing roads, railways, or buildings

2. Narrow streets with numerous buildings

3. In busy downtown areas, trenching is inconvenient or disrupts normal traffic flow

4. Complex site conditions and conflicts with other pipelines can also be an option.

Now that pipe jacking has been chosen, how should it be constructed? Let's take a look at the construction sequence and process flow:

1. Construction Sequence

Pit foundation and backrest installation - Guide rail installation - Bearing wall installation - Main jacking equipment installation - Pipe jacking machine head installation - Lifting equipment installation - Pipe jacking machine placement - Pipe jacking

2. Jacking Process

Survey and stakeout of the caisson - Installation of the jacking machine frame and main jacking equipment - Pipe jacking machine installation, lowering the next pipe section - Pipe jacking machine installation - Pipe jacking completed, lowering the next pipe section - Pipe jacking machine assembly - Pipe jacking force approaching the allowable force - Lowering the intermediate ring - Continue jacking as above - Exit the hole, and separate the pipe jacking machine from the pipe section.
