Example Embodiment
[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0025] In the figure, a special drilling rig for horizontal jet grouting construction of the present invention includes a drilling rig platform, a drilling system and a walking system.
[0026] The rig platform includes a front arch ring 1 and a rear arch ring 2. A sliding device 3 is provided on the front arch ring 1 and the back arch ring 2. One end of the telescopic arm 4 is connected with the sliding frame 3-1, and the other end is conn...

The invention provides a special drilling machine for horizontal rotary spraying construction. The special horizontal rotary spraying drilling machine for construction comprises a drilling machine platform, a drilling system and a walking system. Slipping devices are arranged on a front arch ring and a rear arch ring of the drilling machine platform and drive the drilling system arranged on a tower to move along the front arch ring and the rear arch ring, and then a drill pipe can be quickly and accurately positioned. The walking system moves a drilling machine to a working face or out of the working face through a walking device and an auxiliary walking device. According to the special horizontal rotary spraying drilling machine for construction, single-point positioning of a traditional rotation center shaft type horizontal rotary spraying drilling machine is changed into two-point positioning, and positioning is more efficient and more accurate; moreover, the tower of the drilling system is divided into two parts, transportation is facilitated, the function of setting one-time allowed drilling length is increased, and deformation of equipment is avoided; meanwhile, the drilling machine platform, the drilling system and the walking system are ingeniously combined, the flexibility and convenience of movement of the equipment are improved, and repeated dismounting and mounting of the equipment are avoided. The a special horizontal rotary spraying drilling machine for construction can be widely applied to construction operation such as horizontal rotary spraying and advance grouting in tunnels.
Description
technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to construction equipment for tunnel advance support or formation reinforcement, in particular to a special drilling rig for horizontal rotary grouting construction. Background technique [0002] In the process of tunnel construction, the construction scope often involves weak and poor strata or water-rich strata, which is likely to cause serious problems such as collapse, ground subsidence, water gushing and sand gushing. Numerous examples of tunnel projects at home and abroad have proved that the application of horizontal jet grouting reinforcement technology in weak or water-rich formations has a good advanced reinforcement effect, and has the characteristics of pollution-free construction, simple and safe operation, etc. However, since most of the horizontal rotary grouting construction drilling rigs currently on the market are non-integrated construction...
