Calculation process and gist for trash rack s rest pier design are developed in this paper,which serves as a reference for similar projects.

Based on the experiences with the long distance water delivery with big diameter pipes and the urban sewerage works,they point out the working conditions,the selection of the pipe specifications and the qualification test method of the pipes of glass fibre reinforced plastics with sands used in water supply and sewerage works,and discuss the pipe base,backfilling and buttress which ha.

How to determine allowable deformation and indicatrix of observation accuracy in longitudinal displacement of anchorage block and vertical displacement of boththe anchorage block anti the buttress are emphatically discussed.

Combining construction of main pier bearing platform of Panyu Municipal Bridge #3 Extension Project by adopting craned concrete box, this paper introduces construction of bottomless craned box for cofferdam with similar elevation of bearing platform and river bed.

As a variable cross-section continuous box girder bridge, Shanghai Songpu Bridge III adopted the steel box construction technology, and its middle main pier bearing platform was round-shaped by solid reinforced concrete.

Combining with engineering practice,it typically puts forward method of adopting prefabricated pieces concrete as inherit platform bank cover concrete construction,expatiates constructing points of bottom mould,solves the problem of plentifully using rolled steel in high-frusta inherit platform bank cover concrete construction,enhances constructing quality at the same time.
