(1) Check the hydraulic system, top iron, back, guide rails, supports, etc. before the rectangular pipe jacking machine is jacked in. It can be jacked in only after it is safe.

(2) The mud-water balance pipe jacking machine installs the top iron in accordance with the requirements of safety technical disclosure. The top iron must keep the center under pressure and the force is even. The top iron, between the top iron and the back must be padded.

(3) The excavator must be in the pipe before jacking, and observe the situation before the pipe during jacking. If abnormalities are found, immediately notify the top pick operator to suspend processing.

(4) If collapse, back deformation, top iron twisting, sudden change of top force, etc. are found during jacking, the jacking must be stopped immediately, and measures must be taken to confirm safety before proceeding.

(5) During jacking operations, the jacking pick operator must follow the instructions of the excavator. During jacking, no one is allowed on top of the top rail or on both sides of the top rail.

(6) When crossing a railway section, you must closely cooperate with the railway management personnel and abide by the railway management unit's regulations on jacking. Jacking is strictly prohibited when the train passes. Pipe jacking machinery

The technicality of pipe jacking equipment is a professional term that has just begun to be used frequently in recent years. It involves the use of a few foundation pit excavation, that is, the excavation of the working well and the receiving well requires the excavation of the foundation pit, and it does not excavate the foundation pit. The pipeline is not technically used for foundation pit excavation to carry out the laying or dismantling of underground pipelines, and the construction diameter of the pipe jacking is DN800-4500. According to the working well, the water pipe to be pushed into the receiving well is pushed into the receiving well. The water pipe in a working well can shuttle 1,500 meters above the ground, and it can also shuttle through the curve to avoid some underground pipelines or obstructions.

Its technical key point depends on correcting the error of water pipe widening underground. It is very suitable for trenchless pipe jacking paving of large, medium and small pipes. It has the comprehensive role of economic development, high efficiency, and protection of the ecological environment. The advantages of this type of technology are: no foundation pit excavation; no relocation, no damage to pavement buildings; no pollution to the environment; no harm to the section deformation of the pipeline; time-saving, high efficiency, safety, and low cost of comprehensive projects.

This technology is commonly used in the trenchless pipe jacking of various pipelines such as underground sewage pipelines, gas and oil pipelines, and communication cables in large cities in the more developed coastal areas of China. It can pass through rebirth roads, railway lines, highways and bridges, mountains, rivers, Asia and Europe, and all road buildings. Choosing this technical engineering construction can save a large amount of land acquisition costs, reduce air pollution and road blockage, and have obvious economic and social and economic benefits.
