Embodiment Construction

[0059] Such as Figure 3 to Figure 8 As shown, the high-stability rectangular section underground tunnel structure of the present invention includes a tunnel body, which is composed of a tunnel roof 1 , a tunnel left side wall 201 , a tunnel right side wall 202 and a tunnel floor 3 . Wherein, the tunnel roof 1 includes a flat plate portion 101 and a plurality of vaulted portions 102. The flat plate portion 101 and the vaulted portions 102 are formed by pouring reinforced concrete. The top surface of the side wall 202 is rigidly connected with the two.

[0060] The above-mentioned dome 102 is a hexahedron with a bottom cavity 1a, and the hexahedron is composed of a horizontal top wall 1021, an inclined front wall 1022, an inclined rear wall 1023, a trapezoidal left wall 1024 and a trapezoidal right wall 1025. The trapezoidal left wall 1024 and the trapezoidal right wall 1025 are all vertically arranged on the flat plate part 101, the outer wall surface of the trapezoidal left ...

Abstract

The invention discloses a high-stability underground tunnel structure with a rectangular cross-section and a construction method of the high-stability underground tunnel structure. The underground tunnel structure comprises a tunnel main body; the tunnel main body consists of a tunnel roof (1), a tunnel left side wall (201), a tunnel right side wall (202) and a tunnel bottom plate (3); the tunnel roof (1) comprises a flat plate part (101); the flat plate part (101) is arranged on the top surfaces of the tunnel left side wall (201) and the tunnel right side wall (202) and is in rigid connection with the tunnel left side wall (201) and the tunnel right side wall (202); the tunnel roof (1) further comprises a plurality of vault parts (102); each vault part (102) is a hexahedron with a bottom surface concave cavity (1a). The high-stability underground tunnel structure with the rectangular cross-section has the advantages of high stability, low construction cost and mature construction technology and is especially applicable to an underground tunnel with large load-bearing capacity, large span and limited construction range.

Description

technical field [0001] The invention relates to a high-stability underground tunnel structure with a rectangular section and a construction method thereof. Background technique [0002] As the pace of urban construction continues to accelerate, there is an increasing demand for the construction of super-long-span, multi-lane underground tunnels. At present, the common cross-sectional shapes of multi-lane underground tunnels are circular, rectangular, elliptical, double-circular, and multi-circular. However, their structural cross-sectional area utilization rate is low, resulting in large excavation area, land acquisition, and high project cost. ; however, the early-developed rectangular section tunnels with high utilization rate of structural section area are gradually neglected. This is because the conventional rectangular section tunnels have poor spatial mechanical performance. When the upper load is large or the unsupported span of the tunnel is large , the mid-span dis...
