A new type of tunnel boring equipment

Abstract

A novel tunneling device is characterized in that a steel arch is stored above a shielding set, and a reinforcing mesh is stored on the machine body of a cantilever tunneling machine; a work platform is connected with the shielding set through bolts; a rear guardrail set and an airborne wet spraying machine are connected onto the work platform through bolts; a cutting arm cover plate and a support rib plate are connected to the front of the cantilever tunneling machine through bolts; a front guardrail set and an inner folding plate are connected onto the cutting arm cover plate through bolts; an outer folding plate and the inner folding plate are hinged through a pin shaft. The novel tunneling device has the advantages of advanced design, simple structure, convenience in use, high work efficiency, low manufacture and use costs, and high safety and reliability; the protection function of the shielding set is utilized to guarantee the safety of manual operations; the mounting process of the steel arch is simplified, the number of operators is lessened, and the labor intensity of the operators is reduced. Therefore, the novel tunneling device is an ideal tunneling device.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and in particular relates to a combined equipment with multiple functions such as cutting, protection, anchoring and wet spraying, which is applied to tunnel construction. Background technique [0002] In the field of tunnel construction, the drill and blast method or the tunnel boring machine method are often used for tunnel excavation. During the construction of the drill and blast method, a large number of operators are required to support the tunnel, the labor intensity is high, the progress of the project is slow, and the safety of the working environment is low. [0003] TBM construction can be divided into full-face TBM (TBM) and cantilever TBM. Due to the fully mechanized construction, the full-face tunnel boring machine method (TBM) has fast construction speed and good safety, but the whole set of equipment is expensive, the construction process is complicated, and...

AI Technical Summary

Problems solved by technology

Due to the high level of surrounding rock and complex geological conditions in the tunnel construction site, the cantilever roadheader lacks safe and reliable protective equipment due to its own functions and working space limitations. Operators often work under simple protection or no protection. under great threat

In addition, during the support process, the steel arch installation, anchorage and concrete spraying work of the tunnel excavation section requires a large number of operators to work for a long time and with high intensity. It is difficult to guarantee construction safety, and the project progress is slow, making it difficult to meet the construction schedule requirements.
