Description

technical field [0001] The invention relates to a multifunctional tunnel construction operation vehicle. Background technique [0002] In order to improve the safety factor of tunnel construction and ensure the efficient completion of the construction, it is necessary to carry out support in time during the excavation process of the tunnel, especially for the weak surrounding rock of grade IV and above, it is necessary to carry out various supporting procedures, including Advance support, primary support, secondary lining, etc. Among them, the steps of initial spraying concrete, driving anchor rods, hanging steel mesh, erecting steel arch frames, and spraying concrete again are important measures in the initial support. Because these initial supports have relatively high rigidity, they will also serve as tunnel load-bearing A permanent load-bearing part of a structure.

AI Technical Summary

Problems solved by technology

[0003] At present, the technical level of railway and highway tunnel construction in my country still lags behind that of developed countries, and it is still in the initial stage of mechanized construction. The application of automation and mechanization in the actual construction process is still insufficient. The variety of professional construction equipment Short boards such as fewer, poorer quality, higher failure rate, and mechanical properties that cannot meet construction requirements often lead to protracted construction periods and increased safety risks during construction

Especially in the construction process of weak surrounding rock and soil tunnels, manual operations are generally still the main method, and a large number of manual operations have low construction efficiency, many safety hazards, and greater difficulty in implementing support

[0004] The initial support is a very critical part of the entire tunnel construction process. The installation of anchor rods, steel mesh, steel arches and concrete spraying are the main measures for the initial support. However, most of the existing tunnel construction equipment has single functions. The stability is poor, the structure is unreasonable, the construction cost is high, the difficulty is great, the operation is cumbersome, and the safety factor is low

[0005] However, the traditional tunnel construction technology is relatively backward, and the main construction links still rely on manual work. Although a small number of imported and domestic tunnel construction equipment have appeared on the market, these equipment do not have a high degree of matching with the actual construction environment and are not compatible. Strong, and the corresponding construction cost is high, so it is rarely used in actual tunnel construction

[0006] For the difficult and important part of the vertical steel arch frame in the initial support, the traditional technology mostly uses manual work, and a few mechanical constructions are difficult to achieve the expected effect. The steel arch frame is generally lifted to the palm by the lifting device. The position to be installed on the sub-surface, and then the welding is completed by manpower lifting and supporting (the safety hazard and labor intensity of this process are very large, and personnel injuries often occur), or the installation position of the arch frame is completed by equipment with a grabbing mechanism adjustment, fixation and support, but the general construction equipment has a single function and poor performance, which affects the installation accuracy and efficiency of the steel arch

[0007] In addition, the current tunnel construction equipment on the market does not combine the functions of anchor rod, vertical steel arch frame, shotcrete and other functions to form a complete set of solutions, so the scope of application and popularization is limited, and the integration of these functions can be greatly improved. Reduce costs, energy consumption, improve efficiency, and reduce potential safety hazards

[0008] The technical purpose of the present invention is mainly aimed at the shortcomings and defects of relevant tunnel construction equipment in the current market, and develops a fully functional, strong adaptability to different working conditions, stable and safe performance, which can improve construction efficiency, reduce safety hazards, reduce Multifunctional Tunnel Construction Work Vehicle for Construction Cost
