Embodiment Construction

[0018] As an embodiment of the present invention, the following first combines figure 2 The structure and working principle of a fluid balance subdivision assembly jacking shield machine of the present invention are introduced. like figure 2 As shown, the fluid balance subdivision assembly jacking shield machine of the present invention includes a cutting device (1), a jacking device (2), a jacking cabin (3), an assembly cabin (4), a sealing door (5), a fluid Conveying device, underwater installation robot seven parts. The cutting device (1) is an appliance located at the machine head position to cut the rock and soil mass, and the corresponding cutter head of the existing shield machine or pipe jacking machine can be used. The jacking device (2) is a device that provides power for pushing the shield machine forward, and a combination of multiple sets of jacks can be used as the jacking device (2). The jacking cabin (3) is located between the cutting device (1) and the as...

Abstract

The invention relates to a construction method for assembling jacking shield with fluid balance subdivision and a shield machine used in the field of shield tunnel construction. Isolate, open the assembly cabin (4) to place the tunnel segment (6); then close the assembly cabin (4) and input enough fluid; cut the rock and soil again, jack into the jacking cabin (3), and install the prefabricated tunnel with an underwater robot Segment (6); the shield machine used in the method comprises a cutting device (1), a jacking device (2), a jacking chamber (3), an assembly chamber (4), a sealing door (5), a fluid conveying device, Seven parts of the underwater installation robot, the invention greatly improves the construction speed and safety of shield tunnels, has little disturbance and low cost, and can be widely used in shield tunnel construction.

Description

technical field [0001] The invention relates to the field of shield engineering construction in the field of civil engineering. Background technique [0002] Shield construction is the main construction method of tunnel construction at present. Shield machines were imported from abroad at the earliest. In the near future, domestic production of shield machines can begin. The shield construction method can realize tunnel construction without excavation, and is widely used in highway, railway and subway construction projects. In the early stage, the mud balance shield machine was mainly used. At present, the earth pressure balance shield machine has begun to be used in engineering. The shield construction is mainly to construct the shield well first, then place the shield machine underground from the shield well, cut the soil at the front of the shield machine through the cutter head of the shield machine, and use the shield machine body to temporarily Support the surroundin...
