Description

Technical Field

[0001] This invention relates to the construction of utility tunnels, and in particular to a method for constructing a waterproof structure at the connection of a prefabricated integrated utility tunnel. Background Technology

[0002] The construction process of prefabricated integrated utility tunnels involves prefabricating concrete components in a factory using templates, then transporting them to the construction site by truck. Cranes then lift the components to their designated locations, assembling them into the prefabricated integrated utility tunnel. During assembly, to ensure connection stability and relative sealing, one end of the tunnel is made convex and the other concave. To facilitate docking between adjacent tunnels, the outer surface of the convex end and the inner surface of the concave end are both made into matching slopes. However, this side-lying Z-shaped docking surface structure can cause water to seep downwards through gaps at the docking surface when there is significant surface water leakage. This water can quickly drip onto the various interconnected lines inside the tunnel, causing adverse effects. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned technical problems, thereby providing a construction method for a waterproof structure at the connection of a prefabricated integrated utility tunnel, preventing surface water from seeping into the utility tunnel.
