The experiment was carried out according to the method for determining the toxicity of drinking, ground, surface and sewage water, chemical solutions by measuring the germination index, average length and average dry weight of seedlings of cress seeds (Lepidium sativum).
As a control, distilled water was used.

(1) The hydraulic pump catheter with side water inlet is communicated with the model, and give the model filled with water.
In the second stress stage, the hoop stress increases rapidly and the fiber layers bear most of the water pressure when water pressure eventually reaches the ultimate strength of the adhesive layer or component failure.
The yield water pressure about steel tube is 3.4MPa.Reinforcing one layer of carbon fiber sheet and reinforcing two layers of carbon fiber sheets is differently to 3.7MPa and 4.0MPa water pressure to have yield deformation.
Therefore, it must be familiar with the reinforcement technology professional team to make construction and operation, in order to ensure the quality of paste.

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.

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.

Spray cooling water or foam and dilution steam,to protect the site personnel and make the leakage dilution into non-combustible .Use explosion-proof pump metastasize to the tank or special collector ,recycling or shipped to the disposal of waste disposal sites.
To make technical specification of environmental risk management firstly, clear understanding of various of CH3NO2 emergency treatment techniques and to strengthen the training of professional personnel,the Propaganda of society in general levels, guideing the different types of chemical production enterprises, to carry out environmental risk management and popularize the knowledge of environmental risks of chemicals.

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).

Introduction In most of our cities there were built the housing estates which have always been subject to criticism of professional and general public.
Internal water supply was much more variable for the design of each distribution.
An evaluation of the current status of water supply, that is, material and dimensions of the existing pipeline was performed.
Dimensions of pipes for cold water distribution were sufficient.
The hot water supply was designed by local heating method, which was resolved within a heat source for the residential unit.

It mainly advocates the land, energy-saving, water saving, and materials as well as the protection of the eco natural environment, which is in close connection with the development needs of the times, with the changing need of the development of the times, however, the design requirements and the level of green building of a new socialist countryside put forward higher requirements, and thus to the green from the traditional high energy consumption building efficient architectural changes in the pattern of ecological environmental protection is not only a trend, is also the only way to a new rural building society for.
In addition, many of the rural seat of government in the process of construction and development of new rural, mostly hired the architect of the city, to transform the existing building, however difficult due to lack of funds and personnel as well as technical aspects, together with many rural building designers mostly a lack of professional training, the design of the building mostly follow the traditional design, not only occupy the land resources, but also spent a lot of manpower, material and financial resources, the environmental impact caused damage to the environment, both is not conducive to the protection of the ecological environment, more is not conducive to the building of new countryside.
From the hydrothermal environment system design point of view, green building water-saving measures can be taken to: adopt water-saving and energy-efficient water supply facilities; build rainwater collection systems, sewage treatment system in place sewage treatment into water, landscape water specifically designed and its inclusion in the water system are taken into account.

Commercial Concrete Quality test Jinyang ZHANG 1, a 1Anhui and Huai River Water Resources Research Institute, Bengbu 233000, Anhui, China a13605523751@139.com Keywords: commercial concrete, rebound method, concrete strength, plastic cracks Abstract.The appearance of commercial concrete has heightened architectural construction level, improved construction civilization and offered the guarantee of the popularization and application of new tech significantly.
Its occurrence symbolizes the further professional job division in architecture and building industry to strengthen constructional level, improve constructional civilization and guarantee the popularization and application of new tech conspicuously.
The reason lies in that commercial concrete is more transportable and higher in water/cement ratio and it has more sand percentage in order to let it wrap the aggregate to eliminate the pump pipeline blockage.
The additive’s high water-reduction rate is always regarded as a positive factor, yet many tests show that the compatibility between additives and cement is an important issue to be thought when an additive is being chosen, moreover, the amount of additive dosage is also critical, which shall only be determined after dosage test.
When the said concreting was completed and started to do other job, water seepage was found successively on the ceiling slab, see Fig.1 .
