A kind of near continuous tunnel group ventilation test device and manufacturing method

Abstract

The invention discloses a ventilation test device and a manufacturing method for a group of adjacent continuous tunnels. The test device includes four sections of main tunnels: upstream of the left line, downstream of the left line, upstream of the right line, and downstream of the right line. The four main tunnels are The two-way double-hole approach continuous tunnel is divided into a left line and a right line, and the middle of the four main tunnels is a close opening section. The present invention combines four sections of main tunnels, and can arbitrarily adjust the longitudinal distance between the upstream and downstream tunnels and the transverse distance between the left and right line tunnels, thereby evaluating the distance between adjacent tunnels, the transverse distance of tunnel groups, the tunnel temperature, The impact of traffic flow and speed in the tunnel on the ventilation and sewage discharge of the tunnel group not only saves the production cost of the model, shortens the production cycle, but also greatly reduces the evaluation error and ensures the accuracy of the evaluation results.

Description

technical field [0001] The invention relates to a tunnel ventilation test device, in particular to a close-to-continuous tunnel group ventilation test device and a manufacturing method. Background technique [0002] With the continuous expansion of the urbanization process, the scale of cities and towns has also increased, and the number of traffic buildings has continued to increase. Urban traffic is the "culprit" of air pollution. The backward transportation facilities and large population concentration make traffic congestion a prominent problem in many large cities at home and abroad. In order to alleviate the overload of urban traffic, tunnels have become an important measure to alleviate traffic congestion and the shortage of urban land resources. Because tunnels are mostly built in areas with heavy traffic and high density of people, they often face severe environmental constraints. Understanding their ventilation characteristics and pollutant diffusion characteristi...
