Abstract

The invention relates to a multifunctional parallel adit, which belongs to the technical field of tunnels and comprises a tunnel body arranged along the extension direction of a main tunnel. A pavement cover plate is arranged in the hole body to divide the hole body into an upper channel and a lower channel which are arranged up and down; the upper channel is used for ventilation and personnel evacuation; the lower channel is used for draining water and is communicated with a karst pipeline of the tunnel; the hole body is divided into an air duct branch hole and a drainage branch hole close to the hole opening of the main hole; the air duct branch hole extends upwards to a wide terrain position or is connected into a tunnel fan room; a safety channel and a drainage channel which are communicated with the upper channel and the lower channel of the tunnel body respectively are arranged in the drainage branch tunnel, the drainage channel is connected into a tunnel opening drainage system of the main tunnel, and the safety channel is provided with a fireproof door to prevent air leakage. Idle waste of the ventilation shaft and the drainage tunnel can be effectively reduced, the construction cost is saved, tunnel construction and operation risks are reduced, tunnel drainage is assisted under the condition that extreme water inrush occurs near the tunnel, and the safety disaster prevention capacity of the tunnel is improved.

Description

technical field [0001] The invention belongs to the technical field of tunnels, and relates to a multifunctional flat guide. Background technique [0002] The ventilation shaft of the tunnel is used for tunnel ventilation, and its function is single. The ventilation shafts of some tunnels even only have the function of smoke exhaust shafts, which are only used for tunnel smoke exhaust when a fire occurs in the tunnels, and remain idle for a long time during the operation of the tunnels. [0003] The drain hole of the tunnel is used to assist the drainage of the tunnel. In the karst tunnels of long expressways with complex geological conditions, in order to avoid the extreme rainstorm weather conditions during the tunnel construction and operation, the drainage in the tunnel is not timely, resulting in catastrophic accidents. Some tunnels are often constructed after construction or operation for a period of time. Water holes assist tunnel drainage. [0004] Most of the spa...
