Abstract

The invention discloses a tunnel pavement structure damaged by waterproof damage, which comprises a composite porous water-permeable asphalt pavement layer, an asphalt gravel layer, a graded gravel layer, a leveling layer, a double waterproof layer, and a three-dimensional porous steel layer from top to bottom. For the fiber concrete layer and the base layer, a plurality of water seepage drainage pipes distributed longitudinally along the pavement structure are arranged along both ends of the tunnel pavement. A reinforcement layer is provided, the reinforcement is a composite honeycomb structure, the composite honeycomb structure is composed of a plurality of composite honeycomb hole units, the raw materials of the double waterproof layer include methacrylic resin, propylene oxide polyether, etc.; Waterproof layers and water diversion channels are set between the layers, which can effectively block surface water seepage and underground water seepage, and prevent tunnel pavement water damage by combining prevention, drainage, interception and blocking.

Description

technical field [0001] The invention relates to the field of tunnel pavement structures, in particular to a tunnel pavement structure waterproof and damaged. Background technique [0002] As the throat of highway traffic, tunnel often plays a role in traffic control. No matter in the process of tunnel construction or operation, groundwater is an unavoidable problem. Groundwater infiltrates into the pavement structure through the cracks in the rock mass or the lower layer of cement concrete, making the tunnel pavement structure "soaked" in water. Under the action of groundwater and traffic load, the tunnel pavement will be damaged by water in different degrees. Water damage to tunnel pavement not only reduces traffic safety, increases the accident rate, but also greatly reduces its service life and increases maintenance costs. The tunnel controls the traffic and is the throat of the road. The pavement conditions of the tunnel have a great influence on the traffic capacity ...
