This paper describes the development of the EPS polystyrene insulating panel, the make - up of the components, itsmain technical nature, a suggestion made after years of engineering practice of the way to handle teh joint point in the EPSPolystyrene insulating panel design, its advantages over concrete and reinforcement and its application to large or medium sized projects within China.

Design and test research of new type intercooler core;

The quality of the core of prefabricated drains is one of the key issues in improving soft soils by drained consolida-tion and in practice,it can be judged if it meets the engineering requirements only by visual inspection.
