With the promotion of the construction of underground pipe corridors in China, the small rotary drilling rigs of Taixin Machinery have been constructed on a number of construction sites. At present, the Thai KR80 small rotary drilling rig is under construction on the underground pipe corridor in Hanzhong City, Shaanxi Province. The site requires a 16m pile depth and a pile diameter of 800mm. The construction stratum is mainly composed of soil layers and sandstone layers. The average hole forming time is about 50 minutes.

Due to the limited construction terrain, it is sometimes necessary to enter deep pits for construction, and it is difficult to construct large-scale machinery. The KR80A small rotary drilling rig is suitable for such construction due to its small size, light weight, high power, and low height. Its compact and flexible operation is fully demonstrated.

Another big advantage of the KR80 rotary drilling rig is its overall transportation. It not only saves the customer a great deal of freight, but also saves a lot of time for the customer. The drill rig can be put to work. Due to its efficient construction results, the customer is very satisfied with the KR80's construction capabilities.

The city underground comprehensive pipe corridor, that is, a tunnel space is built underground in the city, integrates municipal, power, communication, gas, and other pipelines, and has special inspection openings, hoisting, and monitoring systems to implement unified planning, design, and construction. And management. Avoid laying and maintaining underground pipelines frequently excavating roads and causing impacts and disturbances on traffic and residents' travel, maintaining the integrity and aesthetics of roads, and solving the ills of “Ziziping”. At the same time, the line is in trouble, and the overhaul workers can drive the vehicle into the underground pipe gallery for rapid repairs to ensure that the quality of life of the residents is not affected, thereby further improving the quality of the city. The country is vigorously promoting such comprehensive projects in various cities. Thai letter machinery is ready to contribute to the national construction.
