Description

Technical Field

[0002] With the development of economy and the progress of urban construction, box beam has become the most important component in bridge engineering. In the process of making box beam, a box beam body with a cavity inside is cast first, and there are some anchor holes on the end face, which need to be blocked during construction.

[0003] The existing blocking method usually adopts the method of blocking the anchor hole first and then blocking the cavities at both ends by bricklaying and plastering. This method has the problems of cumbersome and complicated procedures and long production cycle. In addition, wooden boards are used for blocking. Due to the insufficient strength of the wooden boards, they are prone to tilting and lateral displacement. At the same time, the stability of the wooden boards is relatively poor. At the same time, the flatness of the rear end surface after blocking is poor, and it may also cause the density and strength of the blocking mortar to be difficult to control. There may also be problems with poor blocking. At the same time, these methods cannot realize the one-time casting of the non-continuous section of the box girder anchor and the end concrete.
