Description

Technical Field

[0001] The utility model relates to the field of tunnel construction, in particular to a small-section water diversion tunnel secondary lining concrete curing trolley. Background Art

[0002] The water diversion tunnel has the following characteristics: small cross-section, narrow working space, harsh environment inside the tunnel, and due to the construction technology, the secondary lining construction is carried out separately from the tunnel excavation. After the secondary lining is poured, there is a lack of maintenance trolleys and it can only rely on manual maintenance, which is time-consuming and labor-intensive.

[0003] As the construction of the tunnel's secondary lining continues to advance, the tunnel's maintenance distance continues to increase, and the tunnel's maintenance water source and power system cannot keep up. Furthermore, the tunnel's small cross-section makes it impossible for normal spray equipment to maintain the tunnel using a vehicle-mounted spray device. After maintenance, concrete attachments still remain on the tunnel's inner wall, affecting its appearance and causing an uneven surface. These attachments may affect the concrete's waterproofness and durability, increasing subsequent maintenance costs and making cleaning more difficult. At the same time, dealing with these attachments may extend the construction period, affecting the progress of construction and increasing costs. Therefore, we propose a small-section water diversion tunnel secondary lining concrete curing vehicle to address these issues. Utility Model Content
