I. Overview of TL-40 rig portable drilling rig is anchored by the technical production department and field sales engineers team composed of fusion cases many years experience in the construction and development of cutting-edge technology to create synergies. Its excellent drilling performance, highly efficient and stable construction efficiency deep in the majority of customers pro-gaze. Second, the application of electric fields TL-40, semi-split anchor rig is mainly used in hydraulic power plants, highways and railways mountain slope treatment anchor reinforcement, tunnel shed advance support, foundation piles stayed anchor, anti-floating bolt, embankment reinforcement, hydroelectric dam and dam foundation seepage treatment, drainage holes, mine and quarry blasting holes, micro pile hole and other projects, especially for the drift, eggs and gravel stratum Broken strongly weathered rock formations deep cover with pipe drilling, in particular, to reflect its efficient, high-quality performance, to achieve the purpose of rapid drilling through complex formation, has a broad background in all kinds of applications in geotechnical engineering Anchorage. TL-40 electric, hydraulic split half anchoring drilling rig is suitable for vertical or inclined drilling drilling equipment for the construction process the following methods: * No circulating drilling fluid spiral * DTH hammer (pneumatic impactor) drilling * * Air circulation drilling mud positive DTH drilling pipe * single-action double pipe drilling Third, the performance characteristics of a rigorous structure, small size, light weight, removable strong, easy slope construction scaffolding overhead and reasonable layout conduct operations, remote operation helps secure and efficient construction. Demolition convenient, easy removal and cleaning and maintenance. 2, high performance rig rotary torque of 1700Nm, can be given from the pulling force 25KN. 3, the hydraulic circuit using scientific integration circuit, failure rate, light weight, stable and efficient productivity. 4, the hydraulic circuit with double insurance, in order to prevent the oil back into the oil and overloads. Overload occurs and the implementation, effective accident prevention hole drilling rigs and wells. 5, inheritance, and application of the "extension" series of anchor rig all parts of mature experience, performance has been a reliable guarantee.
