Efficient constant-temperature and constant-humidity tunnel automatic maintenance equipment

Abstract

The invention discloses efficient constant-temperature and constant-humidity tunnel automatic maintenance equipment. The equipment comprises at least two maintenance trolleys arranged at an interval,each maintenance trolley is provided with a support matched with the shape of the arch face of a tunnel, a sealing air bag is fixed between every two adjacent supports, after the sealing air bags areinflated, a sealed space is formed between the sealing air bags and the inverted arch surface of the tunnel, the sealing space is connected with a steam generator, and the steam generator injects steam into the sealing space to maintain the inverted arch surface of the tunnel. According to the efficient constant-temperature and constant-humidity tunnel automatic maintenance equipment, the sealingspace is formed between the inflated air bags and the inverted arch face of the tunnel, steam is inflated into the sealing space, steam is used for maintenance, the problem that in the prior art, water resources are wasted is solved, and the problem that in the prior art, the requirements for water pressure, water amount, tunnel height, tunnel depth and the like are limited is solved.

Description

technical field [0001] The invention belongs to the field of tunnel maintenance, and more specifically relates to a high-efficiency constant temperature and humidity automatic maintenance equipment for tunnels. Background technique [0002] In the tunnel, when a high-speed train passes through the tunnel, a large wind tunnel effect will be generated, which will easily generate a large pressure on the concrete on the inner surface of the tunnel. Therefore, the tunnel structure must not only meet the settlement deformation, but also withstand the wind pressure when the train passes. To make the tunnel structure stable when the train passes, the concrete surface will not fall off, and the safety of the train will not be endangered. This requires the tunnel concrete not only to have sufficient strength, but also to have durability. After the tunnel concrete is poured, if the weather is hot and the air is dry, if the maintenance is not carried out in time, the moisture in the con...
