In view of the problems encountered in ventilating design of civil air defense basements, discusses the applicability of related codes, the conversion design of ventilation systems, the installation of embedded tubes across the protective close wall etc.

This paper introduces the damage reason with tract foundation under 120 tons converter and presents the restructuring plan, which include resolving the loose problem about tract foundation under converter, orbit deformation and the out-of-gear between the built-in fitting and concrete.

Preformed inserts were made of two kinds of common used materials and made in two different structures.

Design and construction of embedded parts of hydraulic architecture;

There are a large number of embedded parts in industrial buildings.

Construction organization of the sluice gate and embedded parts of the Zuojiang multi-purpose dam project;

Installation of the main embedded parts for verical spindle impulse turbine with a double jet;

Via the MTS, the structure is designed including the general analysis, check of composite beams, design of studs of composite beams, design of embedded parts and design of beam column connection etc.

Through analgzing the features,formation causes and harm of common quality defects of wharf s embedded members,we put forward corresponding measures,by which a satisfactory result has been achieved.
