Introduction Xiashan ancient village, located in Kaihua county in the Qiantang river headstream, well preserves traditional pattern of village and a large number of historic buildings, representing a combination of farming-studying culture, clan culture and commercial culture, a cultural landscape example of the harmony between man and nature and a model of water transport culture in Qiantang river basin.
In recent years, vigorous activity of new rural construction in the whole country includes the rural water conservancy, roads and other infrastructure, rural living facilities.
There is no professional management staff at town government level for daily administration of ancient villages.
Only eco-green agricultural production develops toward the professional, brand, commercial, ecological direction, can the cultural tourism and rural tourism increase the added value of agricultural products, achieve economic development, increase farmers' income and pave a new way of reviving the ancient village. (3)Integration of traditional architecture and modern life.
The goals of sustainable development for Xiashan Village are in four aspects: family with coexistence of farming-studying and doing business, water and mountain scene, cultural heritage, traditional landscape for tourism. (1) Renovation of the natural environment of the ancient village.

Introduction The major environmental risks of the highway that distributed in water environmental sensitive regions, which including central drinking water sources, water source protection areas and class II surface water, are mainly caused by the dangerous chemical transportation accidents.
Once the accidents happened in the water environmental sensitive regions, it would lead to the severe casualties and economic loss, especially caused the water environmental damage.
The environmental risk targets refer to the potential risk acceptors, as to the dangerous chemicals transportation accidents happened in the water sensitive regions; bodies of water are the environmental risk sources.
It is difficult to regulate the environmental fields and risk targets because of the restrictions on the professional ability.
Conclusions The water environmental security impact of the dangerous chemicals transportation accidents is the major environmental risks of water sensitive area express way in operation.

Using common pump the water often easy stopping the pump because of water velocity is less than the pumping water speed, the residents living inconvenience, also affecting the service life of the pump.
Development of electromagnetic vibration pump has a direct practical significance to solve the residents living water intake in northwest area of difficult problem.
Its working principle is: after the power is switched on, alternating current produces alternating magnetic field in the stator around, when the magnetic force is greater than the elastic plate assembly, elastic, rotor suction, suction a shift to the left, the chamber volume between the water inlet of hinge and hinge increases, pressure is reduced, the water hinge is opened, complete absorption process.
Get widely application using reciprocating pump of this type in small reciprocating pump. 2) Vibration pump is self-priming function, use more convenient. 3) Vibration pump is especially suitable for household, the flow head range to meet the household demand, power of small, low cost, water area for household water intake pump, due to the well water storage ability is poor, in order to ensure continuous water supply, electromagnetic vibration pump because of its superior performance, is the ideal choice. 4) Electromagnetic driving vibration pump first electromagnetic drive mode and volume pump combined and applied in household, its speed can reach 10 below, is a breakthrough of low specific speed pump. 3.
However, with the drastic increase of water demand, in the nineteen twenties, low-speed piston pump flow is limited gradually replaced by high-speed centrifugal pump and rotary pump.

It is used for the construction of sewage networks, water supply networks, and undercrossing works in urban areas.
The lithology of the zone comprised of soft clays and silty sands; the ground water level was determined at -6.00 m to -7.00 m from the ground surface.
The importance of professional studies and designs is emphasized in this directive.
Nowadays, tunnel construction is done with a high degree of automatic procedures and by high-skilled workers and professionals.
The capability to seal the machine protects it from the underground water pressures.

The survey result indicated that the enterprises manufacturing solar equipment in Jiaxing city had formed a complete industrial chain, including manufacturing Semi-finished product glass tube,all-glass evacuated collector tube,water storage tank, waterstop ring, solar stand, solar getter,solar water heater,solar water heater system et al.
Since then, With development of 17 years, Jiaxing had formed the solar energy water heater industrial cluster.
The traditional solar water heater has been unable to meet the city residential building on the solar energy utilization needs, and solar hot water projects can make up for the traditional solar energy water heater; Solar water heating engineering is designed and installed on the basis of specific construction features and the residents of the water demand, which requires the solar energy enterprises reserve a considerable number of engineering and technical personnel.
In order to reduce solar hot water project design and installation cost, I think that the solar hot water project must be made standardization, modularization, which help the solar energy enterprises to seize the market of solar energy solar hot water project, help the solar energy enterprises make effectively after-sale service, help solar hot water projects be widely used; Building Integrating Solar Energy Technology Innovation [2][3][4] Building integrating solar technology is still only at a conceptual stage in the solar industry.
In conclusion, Building integrated solar energy need solar energy enterprises to attract a lot of professional personnel such as architects, solar energy engineers, to research on solar building components.

However, to differentiate the ratio, current techniques are tedious and sophisticated that cannot be easily conducted by non-professional users.
