Embodiment Construction

[0062] With reference to said attached drawings, figure 1 The embodiment of shows that the tunnel to be built wherein obviously can be any type, and can belong to any civil, industrial or municipal tunnel. The tunnel 1 can be built in any type and shape of ground 2 .

[0063] Figure 4 An embodiment of a guided perforation 3 in the upper region of the tunnel 1 is shown, obtained by known devices for guided perforation of smaller diameter holes, for example equipped with figure 2 and 3 Shown is a flute-shaped swing head 4 or an asymmetric head hammer 5, or equipped with mud turbines or other devices.

[0064] The guided punching device is constantly monitored and controlled by radio, magnetic, radar, optical or electrical reference systems, etc., so as to determine the precise position and direction of the punching drill. Guide punching 3 is the initial stage of reinforcement construction.

[0065] Figure 5 The second phase of the reinforcement construction is shown in...

Abstract

The present invention designs a continuous realization method of any type of underground engineering as follows: carrying out reinforcement work (6) before the excavation work, wherein the reinforcement work is implemented through guiding punching holes (3), and the guiding punching holes are placed Periphery of the center of the built tunnel (1), said reinforcement works (6) are formed by filling the punched holes (3) with reinforcements or inserts which are then combined with a The concrete aggregate injected by the jet grouting system can be mixed with the concrete aggregate injected by the jet grouting system, so that the reinforcement works can be formed on the long stretches or the entire length of the tunnel or on the surface of the underground work before the excavation work, and the resistance corresponding to the precise static conditions can be obtained. collapse project.

Description

technical field [0001] The present invention relates to the excavation and preparation engineering technology of various underground tunnels such as tunnels, roads, railways, ditches and underground waterways. Usually, this technique utilizes peripheral reinforcement techniques to create a stable surrounding environment for the forced advancement of the soil during internal excavation and final completion of the project. Background technique [0002] At present, the specific solution of this type of known reinforcement insertion technology is to form a plurality of punched holes on the periphery of all or part of the tunnel, and introduce reinforcements or inserts of metal, glass fiber or other suitable materials into the punched holes, and the Or concrete jets injected under high pressure or other consolidating materials, such as cement mixtures, gels or resins for filling. These cements are mixed with the materials present at the periphery of the tunnel being built. [0...
