Embodiment Construction
[0029] A centralized air supply and exhaust system unit installation construction method includes the following steps.
[0030] S100~Establish a data model to determine the structure size;
[0031] S101~Measure the installation space of each unit in the fan room, and check the size and spacing of the air inlet and outlet;
[0032] S102~Clarify the size of each structural component of each unit, and measure the foundation and fixed point data in the fan room;
[0033] S103 ~ According to the measurement data and unit size data, use drawing software to make a unit model, reserve 15cm space before and after the main unit, adjust and determine the installation position of each component, and evenly distribute the remaining space to the air inlet and outlet between the air valve and the muffler Damper, determine the size of the damper at the air inlet and outlet.
[0034] S200~calculate the structural size according to the modeling in step S100, and construct symmetrically from b...

The invention belongs to the technical field of highway tunnel ventilation system construction, and in particular relates to an installation and construction method for a centralized air supply and exhaust system unit. The technical problems of limited working space, long construction period and low work efficiency in the installation and construction of the existing centralized air supply and exhaust system units are solved, including the following steps: S100 to establish a data model to determine the structure size; S200 to calculate the model according to step S100 Structural size, symmetrical construction from both sides; S300 to decompose construction deviation; S400 to centrally eliminate installation errors and reduce vibration and noise. The invention effectively improves the production efficiency; the technical means of decomposing the construction deviation is beneficial to reduce the accumulated error, especially further reduces the coaxiality deviation of the equipment components, improves the installation accuracy of the equipment, and improves the operation efficiency of the equipment.
Description
technical field [0001] The invention belongs to the technical field of highway tunnel ventilation system construction, and in particular relates to a method for installing and constructing a unit of a centralized air supply and exhaust system. Background technique [0002] Long highway tunnels and subway stations with a tunnel length of more than 5 kilometers adopt the segmented longitudinal ventilation of the delivery and exhaust type, which can effectively reduce the wind speed of the tunnel and reasonably segment the ventilation, with good effect, low noise, and great ventilation. To improve the overall fire prevention and disaster relief function of the tunnel, the ventilation system mainly uses the inclined and vertical shafts of the tunnel as air supply and exhaust channels, and establishes a centralized air supply and exhaust system based on fan rooms and air supply and exhaust towers at the openings of the inclined and vertical shafts. [0003] A single set of ventil...
