Description
Technical Field
The invention belongs to the tunnel construction technology, and particularly relates to an operation platform, a continuous operation system for tunnel construction and an operation method thereof.
Background
In the intelligent building era, comprehensive mechanization and unmanned construction are the necessary trend of tunnel engineering technology development. The drilling and blasting method and the shield method are two main methods for tunnel construction. At present, a complete large-scale shield machine is adopted for constructing a tunnel by a shield method, so that full-process mechanized construction such as tunneling, slag discharge, duct piece assembly, back grouting and the like can be realized, and unmanned construction can be achieved theoretically. The tunnel is built by the drilling and blasting method, which comprises a plurality of working procedures such as excavation, support, waterproof layer laying and hanging, lining pouring, lining health maintenance and the like, and each working procedure is provided with special mechanical equipment or a working bench, so that the realization of comprehensive mechanical unmanned construction faces great difficulty. However, the drilling and blasting method has the irreplaceable advantages and adaptability of the shield method in the aspects of tunnel scale, channel condition, construction site, prefabrication condition and the like, and is still the most important method for tunnel construction in a quite long time in the future.
When the drilling and blasting method is adopted for construction, different types of trolleys and tools exist in each construction step of excavation (rock drilling, charging, blasting and slag discharging), support (anchoring, stand and concrete spraying), construction monitoring, waterproof layer paving and hanging, lining (including binding reinforcing steel bars), maintenance and the like, and the trolleys and tools are supported and arranged on the ground of a tunnel for walking construction, and have great differences in various aspects of geometric structures, sizes, travelling mechanisms, operation control and the like. Meanwhile, the tunnel constructed by adopting the drilling and blasting method is blasted and broken by adopting explosive, the bottom of the tunnel actually excavated is rugged, and the construction site is extremely irregular by adding groundwater for soaking and rolling by vehicles. In addition, when the drilling and blasting method is adopted for construction, according to different stratum conditions, multiple excavation methods such as a full-face method, an up-down step method, a three-step method and a pilot tunnel method can be adopted for excavation, the number, the shape and the size of section blocks of different excavation methods are different, the bottom edge of a tunnel in each excavation stage cannot meet the requirement of comprehensive mechanization, and special construction machines are required to be designed corresponding to special construction conditions. The above factors cause great difficulty in realizing comprehensive mechanical unmanned construction of the tunnel by the drilling and blasting method.
For example, chinese patent application No. 201520901763.3 discloses a multifunctional arch frame for tunnel construction, wherein a working platform is arranged on a chassis provided with moving wheels through a supporting frame, and is supported and moved on the construction ground of a tunnel through the moving wheels. The work platform of the arch frame is only generally suitable for laying and installing the circuit in the later period of the tunnel, and the ground of the tunnel is leveled at the moment, so that the movable wheels can roll conveniently. However, the arch frame cannot be applied to the construction of a tunnel by a drilling and blasting method.

Example two
The first embodiment belongs to a light working platform, and can be used for the construction procedures of scanning the inner wall of a tunnel and the like without bearing a great load. In order to further improve the construction procedures which are required to bear larger loads, the embodiment provides another working platform scheme on the basis of the first embodiment.
As shown in fig. 6, the arch support 1 is suspended and connected to the arch inner wall 61 of the tunnel through the main travelling mechanism 2 and the auxiliary travelling mechanism 3, and in order to realize the construction process that the arch support 1 can bear larger load, an auxiliary supporting system 5 is further arranged on the arch support 1, and after the arch support 1 is moved and positioned to a fixed position, the arch support 1, the arch inner wall 61 of the tunnel and the tunnel ground 62 are supported and fixed, so that an auxiliary support of a working platform in the construction process is provided.
Specifically, the support system 5 includes a lateral support structure 51 and a vertical support structure 52, where the lateral support structure 51 is fixedly disposed on two sides of the arch support 1, and a telescopic lateral support boot that is deployed towards two sides is adopted, and extends outwards through the telescopic lateral support boot, so that the support system can be transversely supported on the arch inner wall 61 of the tunnel; the vertical supporting structure 52 is fixedly arranged at two ends of the arch support 1, adopts vertical downward telescopic supporting legs, is in contact with the tunnel ground 62 downwards through the telescopic supporting legs, and provides vertical support for the arch support 1, and the vertical supporting structure only needs to level two side positions of the tunnel ground and does not need large-area occupied tunnel ground space.
