Construction method of sheet pile type soilless roadbed
A construction method of the sheet pile type soilless roadbed comprises the following steps that a tubular pile matrix is driven into the ground, and gantry crane rails are laid on the portions, on the two sides of the tubular pile matrix, of the ground; pier caps are mounted at the tops of the tubular piles at the front end and the rear end of each row of tubular pile group; a steel hoop is installed on the upper portion of each tubular pile; longitudinal beams are installed on the upper portions of every two adjacent tubular piles; a steel pipe sleeve is installed on the top of a middle pier; a bridge deck is hoisted through a gantry crane on the gantry crane rails, a winch is installed on a bridge deck large plate, a cross beam is installed below a longitudinal beam to support the longitudinal beam, and wedge-shaped combined supports and the steel hoops are dismantled. Soil filling is not needed between the piles, and land is saved. The piles and plate components are prefabricated in a factory in a standardized mode, and economical efficiency is good. During construction, bridge decks are spliced after being supported by longitudinal beams, and the single bridge deck is low in hoisting strength. And after the previous bridge floor is constructed, the steel hoops, the longitudinal beams and the gantry crane can be moved into the next tubular pile matrix for construction, and the construction process can be continuously carried out.
板桩式无土路基的施工方法，包括以下步骤：在地面上打入管桩矩阵，在管桩矩阵的两侧的地面上铺设龙门吊轨道；在每排管桩组的前端和后端的管桩的顶部安装墩帽；在每个管桩的上部安装钢抱箍；在相邻的两个管桩的上部安装纵梁；在中间墩的顶部安装钢管套；通过龙门吊轨道上的龙门吊吊装桥面板，在桥面大板上安装卷扬机，在纵梁的下方安装横梁来托住纵梁，拆除楔形组合支座和钢抱箍。本发明桩间无需填土，节约土地。桩、板构件在工厂标准化预制，经济性好。施工时桥面板通过纵梁托住后再拼接，桥面板单个吊装强度低。而且前一个桥面施工后，可将钢抱箍、纵梁、龙门吊移入下一个管桩矩阵进行施工，施工过程可以连续进行。
