(Summary description)Rectangular pipe jacking machine is flexible and convenient in application The rectangular pipe jacking machine is used for the excavation of underground tunnels. There are more engineering construction soil layers that can be applied. The engineering construction work well is smaller than that of the shield machine and occupies less land. There is no need for closed traffic travel during the whole process of construction. Because it is a trenchless pipe jacking method that does not excavate the ground, there is no pollution of dust and air, and the construction noise is also low. The impact on the surrounding soil layer during the whole construction process is relatively large. It is small, and it can reasonably control the settlement of the road surface and the foundation of the pipeline. The rectangular pipe jacking machine belongs to construction engineering equipment or mechanical equipment. The hydraulic oil pump and hydraulic transmission system used in the machine equipment of the Dushun rectangular pipe jacking machine are all self-supplied by other production lines of the company, so strict supervision of the quality of the machinery and equipment can be guaranteed. Analysis of the function of the rectangular pipe jacking machine The main shaft equipment in the rectangular pipe jacking machine adopts a combined main shaft design scheme. Such a main shaft equipment has a symmetrical structure, a well-proportioned overall support, little vibration to sand, and a reasonable cutting neps of 80%-90%, combined Banner-type cutting boards are often used in the design of type spindles. The spindles using banner-type cutting boards are simple in structure, and cleaning is generally not easy to produce. The friction resistance of sand fluidity is small, the spindle damage is small, and the engineering cost is also reduced.
