Description

Technical Field

[0001] The present application relates to the technical field of power tunnel bearing devices, and more specifically, to a processing device for polysulfide sealant for filling gaps in tunnel segments. Background Art

[0002] The tunnel segment is the innermost barrier of the tunnel, which is responsible for resisting soil pressure, groundwater pressure and some special loads. When the tunnel segment is installed on the annular inner wall of the tunnel, it is necessary to evenly spray special fireproof glue on the inner wall of the tunnel segment and ensure that a uniform coating is formed on the surface of the segment. The special fireproof glue is used to ensure that the segment can effectively prevent fire in the event of a fire. However, the special fireproof glue may be viscous or not viscous enough at room temperature. Traditional processing equipment is only used to heat the fireproof glue and only coat the surface of the prefabricated tunnel segment. The tunnel segment coated with fireproof glue is then transported to the tunnel for installation. During the process, the coated fireproof glue is easily rubbed off by foreign objects, affecting the fireproof performance of the tunnel segment. The spraying equipment, storage equipment and heating processing equipment cannot be integrated into one, so the tunnel segment installed on the inner wall of the tunnel cannot be efficiently coated with fireproof glue in a mobile manner along the tunnel, that is, the traditional fireproof glue coating efficiency is low.

[0003] In view of this, we propose a processing equipment for polysulfide sealant for filling the gaps of tunnel segments. Utility Model Content
