技术领域technical field
本发明涉及隧道通风技术领域，更具体涉及一种侧墙式射流风机模块化安装装置。The invention relates to the technical field of tunnel ventilation, and more particularly to a modular installation device for a side wall type jet fan.
背景技术Background technique
我国铁路、公路等交通工程修建了大量隧道工程，由于线路标准高，在山区长隧道（铁路隧道长度大于3公里、公路隧道长度大于1公里）、特长隧道（铁路隧道长度大于10公里、公路隧道长度大于3公里）的占比很大，大大改善了运营条件。根据规范要求，铁路隧道长度大于8公里（电力牵引）、公路隧道长度大于1 .5公里应在隧道内设置机械通风，以保证运营期间隧道内的空气质量，一般隧道运营通风大多采用射流风机纵向式通风方式，风机一般安装在隧道拱顶或侧面。对于侧墙安装的射流风机，大多数厂家均是按现场尺寸对风机支架进行一一定制组装，并且进行对应编号，由于支架发货时均为散件状态，所以到了现场后拼装时极易出现拼错的现象，加工难度和安装难度非常大。my country's railways, highways and other transportation projects have built a large number of tunnel projects. Due to the high line standards, long tunnels in mountainous areas (the length of railway tunnels are more than 3 kilometers and the length of highway tunnels are more than 1 kilometer), extra-long tunnels (the length of railway tunnels is more than 10 kilometers, and the length of highway tunnels is more than 10 kilometers. Longer than 3 kilometers) accounted for a large proportion, which greatly improved the operating conditions. According to the specification requirements, the length of railway tunnels is more than 8 kilometers (electric traction), and the length of highway tunnels is more than 1.5 kilometers. Mechanical ventilation should be set up in the tunnels to ensure the air quality in the tunnels during operation. Generally, the vertical jet fans are used for general tunnel operation ventilation. The fan is generally installed on the tunnel vault or side. For the jet fans installed on the side wall, most manufacturers customize and assemble the fan brackets one by one according to the size of the site, and number them accordingly. Since the brackets are shipped in loose parts, it is very easy to assemble after arriving at the site. The phenomenon of misspelling is very difficult to process and install.
