Problems solved by technology

[0003] In the prior art, the shield segment and the above-mentioned structures or equipment are usually connected by means of chemical anchor bolts or pre-buried channels. It is very destructive, and it is very easy to cause problems such as shield segments, cracks, collapses, and leakage during initial installation or replacement; however, it is connected by a pre-buried channel, which cannot be replaced after the channel is pre-buried, and the channel is prone to corrosion and failure. As a result, the equipment and pipelines fall off, which has great hidden dangers and affects the safety of the daily operation of the subway. The existing installation method is cumbersome and inefficient, which restricts the construction progress of the subway

Abstract

The invention provides a mounting structure and a mounting method for shield tunnel accessory equipment. The mounting structure for the shield tunnel accessory equipment comprises shield segments, a longitudinal connecting bolt, a steering hanging piece, an arc-shaped slideway and equipment support, wherein the shield segments are provided with shield hand holes at the bottom side; the longitudinal connecting bolt is connected with the two shield segments, and the two ends of the longitudinal connecting bolt extend into the shield hand holes respectively; the steering hanging piece comprises asteering plate and a steering groove, a through hole is formed in the steering plate, and the longitudinal connecting bolt penetrates through the through hole and is fixed through a nut; the arc-shaped slideway is arranged on the bottom sides of the shield segments and is fixedly connected with the steering groove; and the equipment support is arranged on the bottom side of the arc-shaped slideway and is slidably connected with the arc-shaped slideway. According to the mounting structure and the mounting method for the shield tunnel accessory equipment, the shield segments are not damaged, drilling and steel bar planting or expansion bolts do not need to be conducted on the shield segments, a groove does not need to be formed, the integrity of the shield segments of the shield tunnel is guaranteed, follow-up concrete cracking is avoided, the thickness of a concrete protective layer is reduced, and the durability of the tunnel is improved.

Description

technical field [0001] The invention relates to the technical field of shield tunnel installation, in particular to an installation structure and an installation method of auxiliary equipment of a shield tunnel. Background technique [0002] As the world's advanced underground tunnel construction technology - shield tunneling method, it has the advantages of fast construction speed, high lining quality, and small impact on the environment, and is widely used in current underground construction projects. The shield segment is the main assembly component of the shield construction and the permanent lining structure of the shield tunnel, which bears the role of resisting soil pressure, groundwater pressure and some special loads. After the lining splicing of the subway shield tunnel is completed, A large number of electromechanical and pipeline equipment such as ventilation and air conditioning, water supply and drainage and fire protection pipelines, and evacuation platforms m...
