Description

Technical Field

[0001] The invention relates to a concrete rotary spraying reinforcement device, in particular to a high-pressure rotary spraying machine capable of adjusting the drilling and rotary spraying directions in all directions. Background Art

[0002] With the development of subway construction, subway construction in most cities is concentrated in the main urban area of ​​the city. Pipelines, surrounding houses, road greening, commercial plazas, etc. are relatively concentrated. The construction area and the difficulty of pipeline relocation are gradually increasing. Many stations cannot be demolished and pipelines cannot be relocated. As a result, the traditional three-axis mixer can no longer meet the construction needs due to its large area and inability to control the surface uplift. High-pressure rotary spraying construction is prone to cause ground uplift and damage pipelines, and both construction processes can only be constructed vertically, which has great limitations. The walking rotary spraying drilling rig for road engineering construction, which was published by the China Patent Office on April 10, 2018, with the patent number "201720929172.6", includes a drilling rig body, a connecting arm and a drilling device. One end of the connecting arm is connected to the drilling device, and the drilling rig body includes a control console, a connecting mechanism and a walking mechanism for movement. The end of the connecting arm away from the drilling device is movably connected to the connecting mechanism, and the control console and the connecting mechanism are both arranged at the upper end of the walking mechanism. The console is used to control the movement of the walking mechanism. Under the action of the walking mechanism, the entire drilling rig can be moved very conveniently. And because the drilling rig is equipped with a connecting arm, the drilling rig does not need to enter the soft soil foundation, but can choose a construction access road or other ground with good bearing capacity for drilling and spraying construction, and each time the drilling rig can be moved after completing the construction of multiple jet grouting piles, which improves the efficiency of construction. Although this device can move, it can only drill vertically downwards, cannot avoid underground pipelines, and cannot meet the needs of multi-angle drilling and jet grouting.
