With the development of high-pressure jet grouting technology, a new dual high-pressure jet grouting process, namely RJP construction method, has appeared. In order to meet the requirements of the RJP method, the XLT-230 full hydraulic crawler jet grouting drill was designed and developed. The drill is easy to operate and meets the RJP process. It is equipped with a large torque and large through-bore power head, with functions of intermittent lifting and directional jet grouting, which is suitable for various engineering conditions. The overall structure and technical parameters of XLT-230 drilling rig as well as the design of main components of the drilling rig are discussed in detail. The hydraulic and electrical systems of the whole rig are also introduced.
