Embodiment Construction

[0059] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0060] like figure 1 As shown, the present embodiment is a kind of urban tunnel ventilation test device with a ramp. The prototype of the urban tunnel ventilation test device is the Zijingang Tunnel in Xihu District, Hangzhou City. The length of the slot is 186m; the total length of the B ramp tunnel is 560m, and the length of the grounded U-shaped slot is 186m; the total length of the C ramp tunnel is 159m, and the length of the grounded U-shaped slot is 130m. The cross-section of the main tunnel is a single-box double-chamber rectangular section with a net height of 5.5m and a net width of 9.75m, of which the net height of the fan section is 6.7m. The clear height of the ramp is the same as that of the main tunnel, the clear width is 7.5m, and the inner wall is made of rough concrete.

Abstract

The invention discloses a city tunnel ventilation testing device with a ramp. The city tunnel ventilation testing device comprises a main tunnel and a ramp, wherein the ramp is connected with the main tunnel by a flexible connecting pipe. As the main tunnel is connected with the ramp by the flexible connecting pipe, the included angle between the ramp and the main tunnel can be adjusted optionally at any time, so as to evaluate the effects of the angle of the ramp on the ventilation and pollution discharge of the main tunnel in the same channel; by adopting the device, the manufacturing cost of a model is saved, the manufacturing period is shortened, the evaluation error is reduced furthest, and the veracity of evaluation results is guaranteed.

Description

technical field [0001] The invention relates to a tunnel ventilation test device, in particular to an urban tunnel ventilation test device with ramps. Background technique [0002] In recent years, with the acceleration of urbanization, the urban population is oversaturated, the building space is crowded, the urban greening is reduced, and the traffic pressure is increasing. Traffic congestion has become a prominent problem in many cities in our country. In order to solve the problem of urban traffic congestion, three-dimensional use of space has become a development trend. As an extension and supplement of ground roads, urban tunnels are easy to plan, short in construction period, low in construction cost, easy to connect with existing ground transportation systems, and effectively improve the urban environment. environment and other characteristics and are widely used. The large-scale urban tunnel groups that have been built abroad, such as the Boston Central Avenue Tunne...
