The hanging baskets are the main equipments in the cantilever casting construction of large-scale prestressed concrete continuous rigid bridge and continuous girder bridge.

In order to demonstrate the feasibility of the construction technique of cantilever casting of a reinforced concrete arch bridge and the rationality of cable force adjustment and construction control,a model test of cantilever casting construction was made by taking the No.

According to the case of Wusongjiang super bridge continuous box-girder cantilever casting construction,the nacelle design principle and typical construction scheme show that nacelle design is uncertain.

Baishagou Bridge is a reinforced concrete box arch bridge with a net span of 150 m,its arch ring adoptes firstly suspended wagon cantilever casting construction in China.

1 Bridge as an example,which lies on the highway from Xichang to Panzhihua,a model test of cantilevering cast construction of arch bridge is made,which simulates roundly the course of cantilevering cast construction.

Using the cantilevering casting method to construct reinforced concrete arch bridge is economical, and it has the advantages such as convenient construction, favorable unity, less maintenance and easier repair when there is no precast space in the construction site or it is difficult to transport the prefabricated parts.

Analysis on the problems of vertical cracks in the construction of arm cast-in-place;
