Application of Simple and Conveninet Composed Deck-forms to Place Concrete of Box Culvert

The simple and convenient composed deck-forms introduced in this paper is suited to place concrete for this kind of box culvert which possesses no high top slab and smaller cross section and for the inverted siphon box culvert with higher and small cross section too. This composed deck-forms have following features： 1） It is a intergral support system, 2） As a whole body it can be demounted conveniently and quickly, and can be contracted, 3） It can be used successively and repeatedly and thereby the use efficiency is high. Compared with the traditional scaffolds, it can decrease a lot of manual labour, lower construction cost, reduce labour strength, and can shorten half time of construction period, raise the economic benefit. Therefore, it is worthy to be popularized in similar projects.
