Taking the assembling of the 40 m long under-deck movable shuttering form used for the simply-supported railway box girders on piers No.

0~022 of Contract I of the Main Bridge,Wuhan Tianxingzhou Changjiang River Rail-cum-Road Bridge were constructed by the 40 m long under-deck movable shuttering form.

Research purposes:Application of key technologies and techniques of self-propelled travelling die carrier casts the long span and large tonnage box beam in place for passenger dedicated line for the purpose of meeting the requirements of rapid construction the bridge of passenger dedicated line.

The beam making construction technique of DSZ32 m/900 t upstroke moving carrier;

Introduced hereby are the features, assembly and erection of the deck mobile formwork carrier adopted in the works, precompaction test, adjustment of the precamber of the main girder and the operation flow, with a summary of the engineering features and measures for assurance of construction safety and quality.

The piers of the Bridge are of single-and double-column piers without capping beams and the concrete continuous box girders atop the piers are constructed by movable shuttering form.

This paper presents the method for construction of the superstructure of the north approach spans of Huangpu Bridge over Zhujiang River in Guangzhou by movable shuttering form under special construction conditions and also the key control points and safety protection measures for construction of long span prestressed concrete box girders by the form.

The upstroke moving die carrier work principles and consolidation shed technique;

The cost analysis on the passenger special line moving die carrier cast-in-place box;
