Another possible method of dissipating the heat from the thermoacoustic air conditioning system is involved heat absorption by water.
This is because water has high heat capacity and it would absorb the heat quickly.
This process is used in many professional-grade thermoacoustic researches where helium gas has led to increase the efficiency and heat transfer across the stack.

It includes water-supply, drainage, gas, heating power, electric power, telecommunication and integrated pipe tunnel, etc.
However, during city construction processing, these varied pipe were destroyed from time to time which resulted telecommunication interruptions, gas leak and water flood etc. these accidents made big loss of country property.
But pipe network such as the gas pipe network and water distribution network pressure was designed circular network.
strPipeType denoted the type of pipe network objects, such as telecommunications, electricity, water supply and so on.
After implementation the system design, it provide geography information and professional pipe network information for some sectors such as urban planning, main water, gas, civicism, communication, electric power, fire protection, transportation industry, public security etc.

The water resources scarcity and solar energy richness give Guanzhong area suitable conditions for rainwater collection and passive solar energy technology.
Through redesigning the building façade, the research group adopts passive energy-saving measures and does confirmatory professional energy-saving software analysis for reconstruction measures to improve classroom optical and thermal environment.
The research group designs providing solar PV panels on south roof of dormitories and office buildings to solve part of the electric power and hot water problems.
The Guanzhong area is located in the northwest of China with an annual rainfall of 625-700mm and its water resource is comparatively scarce [3].
The transformation of building roofs and outdoor floors, rainwater recycling by roof slope and outdoor permeable ecological floor, and reutilization of the daily pollution-free water can effectively alleviate school water pressure and reduce school daily expenses (Fig.7).

As to the cutoff scheme, the dewatering method should be adopted when the pit water amount or the water pressure is great [1].
The key point of the dewatering and drainage program is groundwater pumping, where the water level should be lowered below the pit base, in order to ensure the smoothly concrete pouring and foundation pit excavation.
Set the deep test wells at the northeast corner of the pit, diameter φ800mm, bottom elevation 17.0m, depth 25m and make ensure the pressure water head at -9.1m after the dewatering.
Furthermore, the protection measures have adopted as follows: ① After the light well point played the role controlling water, the excavation of the stage can start and should strictly follow the principle of "dewatering first, excavation later". ② Drainage ditches should be set at the top of the slope and each platform, and then collect water drained by pumps in order to ensure a good drainage system on the construction site. ③ To strengthen the slope protection, the geotextile should be prepared for the soil slope protection in rainy season except plasterring plain concrete on the lowest layer. ④ To guide the construction, the professional staff should be entrusted to monitor changes in groundwater level, settlement, inclinometer and other aspects during excavation.. ⑤ Prohibit the upright excavation deeper than 2m, and strengthen the management and control of the construction site. ⑥ Solutions to emergency: a.
