Embodiment Construction

[0016] Below with the accompanying drawings ( figure 1 ) to illustrate the present invention.

[0017] figure 1 It is a structural schematic diagram of a segmented thermal tunnel anti-sliding strip implementing the present invention. like figure 1 As shown, a segmented thermal tunnel anti-slip strip includes an anti-slip structural unit 12 arranged on the outer peripheral surface 5 of the thermal tunnel structure. The anti-slip structural unit 12 has a segmented structure distributed along the axial direction. Concave-convex structures are formed between segments of the segmented structure. The anti-skid structural unit 12 includes a first section 2, a second section 1 and a third section 7 distributed in sequence from left to right, the second section 1 is a low platform section, and the first section 2 and the third section Section 7 is a high platform section. A second transition surface 3 is formed between the first section 2 and the second section 1, and the slope an...

Abstract

The invention discloses a sectional-type thermal power tunnel antiskid strip. Axial sectioning structures are adopted in an antiskid structure unit so as to form concave-convex structures between sections so that the self weight of the antiskid strip and the structure material using amount can be decreased, horizontal acting force of a stable tunnel structure formed by soil mass can be further increased, accordingly, thrust transmitted from a thermal power pipeline by thermal power pipeline fixing supports is resisted advantageously, the antiskid capability and construction efficiency of the tunnel structure are improved, the safety coefficient of the tunnel structure is increased, and construction difficulty is lowered. The sectional-type thermal power tunnel antiskid strip comprises theantiskid structure unit arranged in the peripheral face of the thermal power tunnel structure. The antiskid structure unit comprises the sectioning structures distributed in the axial direction, and the concave-convex structures are formed between the sections of the sectioning structures.

Description

technical field [0001] The present invention relates to thermal tunnel structure and construction technology, in particular to a segmented thermal tunnel anti-slip strip, which can be both Reduce the self-weight of the anti-slip strip and the amount of structural materials, and increase the horizontal force of the stable tunnel structure formed by the soil, which is beneficial to resist the thrust from the thermal pipeline and its accessories transmitted by the thermal pipeline fixing bracket, and improve the anti-skid of the tunnel structure Capacity, construction efficiency, safety factor, and reduce construction difficulty. Background technique [0002] In the heat tunnel, it is necessary to set up supports to fix the heat pipes. The supports are usually subjected to the thrust of the pipe and its accessories, and the supports transmit these thrusts to the tunnel structure. In order to resist these thrusts, the friction between the soil and the surface of the tunnel str...
