近十年来,随着建筑事业的发展,多层、高层、超高层建筑物的出现,给现场施工组织管理带来一定的难度。为更好地解决现场指挥问题,我们不同程度地在较大施工现场配备无线对讲机,工程上一出现技术、材料供给、人员调配、安全隐患等问题,只要在所控制的距离范围之内,持对讲机的人,可立即收到信息,能及时到位解决问题,为顺利施工提供了方便,也提高了技术经济效益。对讲机可分为无线对讲和有线对讲(即载波电话)两种。无线对讲机:由于发射功率不同所控制的距离也不一样,收发均使用λ/4鞭天线,中等起伏地形,控制距离不小于5km;采用高架天线,控制距离可达30km。一般建筑施工现场可选用控制距离1km和
In the past decade, with the development of construction, the emergence of multi-storey, high-rise, and super-high-rise buildings has brought certain difficulties to the construction management of on-site construction. In order to better solve the problem of on-site command, we have equipped wireless walkie-talkies in large-scale construction sites to a certain extent. Once a project comes up, there are problems such as technology, material supply, personnel deployment, and security risks, as long as they are within the controlled distance range. People on the walkie-talkie can receive the information immediately and can solve the problem in time, providing convenience for smooth construction and improving technical and economic benefits. The walkie-talkie can be divided into wireless intercom and wired intercom (ie, carrier phone). Wireless walkie-talkie: The distances controlled by different transmit powers are also different. Both λ/4 whip antennas are used for transmitting and receiving, and the control range is not less than 5km for moderately undulating terrain. The control distance can reach 30km with overhead antennas. General construction site can choose to use control distance 1km and
