Abstract

The invention discloses a supporting frame for duct pieces of a soil-disturbance-resistant split type shield tunnel. By the supporting frame, the problem that duct pieces of a formed shield tunnel deform easily when soil disturbance occurs above the shield tunnel is solved. Duct pieces (2) are arranged on a shield surrounding rock hole side wall (1); a shield trolley right sleeper (4) and a shield trolley left sleeper (16) are respectively arranged on bottom duct pieces; a right supporting frame bottom beam (7) is arranged on the shield trolley right sleeper (4) along the trend of the tunnel; right supporting frame upright columns (8) and right supporting frame longitudinal beams (9) are arranged on the right supporting frame bottom beam (7) at intervals; a right right-angled-triangle-shaped support (10) is fixedly arranged on the right side of each right supporting frame upright column (8); the structure of a left supporting frame body is the same with that of a right supporting frame body; and an upper supporting frame body is arranged on the upper portion of space between the left supporting frame body and the right supporting frame body. The supporting frame for the duct pieces of the soil-disturbance-resistant split type shield tunnel can be assembled on spot, is simple and practical and can be reused.

Description

technical field [0001] The invention relates to a shield tunnel segment support frame, in particular to a segment support frame for preventing the deformation of the shield tunnel segment when the external soil of the shield tunnel being excavated is disturbed. Background technique [0002] During the construction of the shield tunnel, the shield machine excavates the soil to form the tunnel body, and then uses the assembly machine to assemble the segments on the wall of the formed tunnel body, and uses special bolts to connect the segments in the circumferential and longitudinal directions. A closed annular lining support system is formed through synchronous grouting and secondary grouting through reserved grouting holes in the segment to achieve a force balance between the tunnel support system and the surrounding soil. However, in the process of tunnel shielding, above the formed shield tunnel, soil construction near the shield tunnel, soil loading or unloading, and other...
