We first identify practical constraints in solving resource-tracking problems in an enclosed or partially covered environment. We then compare pros and cons of available localization principles and examine the latest wireless communication technologies, including Wi-Fi, Bluetooth, Ultra-Wideband (UWB) and ZigBee. We find that the ZigBee-based wireless sensor network and the received signal strength indicator (RSSI) localization method are most promising to tackle on-site tracking of construction resources. Finally, we anticipate some application challenges associated with deploying wireless sensor networks for resources tracking in the practical context.展开更多

In the actual construction process, it is able to pass through complex bottom layer and water layer underground without very high requirements in equipment. The actual bearing capacity of single pile is very strong, so that it can be better to adapt to the actual needs of different scales or the different geological conditions in building. And it has been promoted and used greatly in building construction work [1]. This paper introduces the concept of the pore-forming pouring pile technology, analyzes the pore-forming construction technology and the pile construction technology, then talks about prevention problems of the pore-forming pouring pile construction in House Building Project, at last draws a conclusion that the pore-forming pouring pile technology is the most basic construction technology and is the most effective and convenient way of construction.展开更多

The first part provides a brief description of the historical background of ecological activities in China and their major achievements in the past. The second part is a comprehensive review of various types of ecological control activity aimed at the improvement of natural and artificially established ecosystems at the landscape,regional(watershed) and higher levels. The scope of and differences between some ecological terms used in China such as ecological protection, conservation, remediation(rehabilitation), restoration as well as the reestablishment of new ecosystems are elaborated. The review suggests that the term "ecological conservation and construction"should be used to embrace all types of ecological control activity in China. Finally, five guidelines are proposed for promoting the implementation of ecological conservation and construction in China based on the two important governmental documents related to the development of ecological civilization in China.展开更多
