0010010 nbsp;It is based on the structure and working principle of the shield machine, and was successfully developed in response to the needs of the municipal trenchless underground pipe laying project. After practical application, it has the advantages of time and labor saving, safety and efficiency, low construction cost and high digging quality.
0010010 nbsp; While the front-end rotary cutter head rotates, the hydraulic cylinder pushes the whole machine forward, and the cut muck falls into the mud bunker, and then transported to the muck truck, hoisted to the ground Complete a working cycle. It can be jacked up to 50-300 meters at a time, and the pipeline will go along with the excavation without collapse of the soil layer.
0010010 nbsp; According to the design of the diameter of the underground pipeline, determine the corresponding use of the tunneling machine specifications, diameter 800-5000mm, can also be customized according to user requirements.
0010010 nbsp; No larger mud water treatment equipment and construction site are needed to stabilize the working surface with mud, and the method of earth pressure balance is adopted to make construction more convenient. The whole set of equipment has excellent performance, simple and reliable operation, economical and practical. It has been successfully applied in the construction of many crossing culverts and underground drainage pipes, with good results and an ideal working condition.
