The invention relates to a straddle type monorail train track beam line type control method which comprises the following steps that firstly, after a reinforcement cage is bound at a design position and a prestressed steel strand pipeline is laid, a track beam body is formed through one-time pouring of concrete, and the height of the track beam body is lower than the design height of a track beam; secondly, after the track beam body reaches the specified strength, the steel strand is tensioned to apply prestress to the track beam body; and thirdly, secondary pouring is conducted on the top face of the track beam body to the designed height of the track beam, and a leveling layer is formed on the surface of the track beam body. The flatness of the surface of the straddle type monorail train track beam can be guaranteed, and the impact resistance of the track beam is improved.
本发明涉及一种跨座式单轨列车轨道梁线型控制方法，包括以下步骤：步骤一、在设计位置绑扎钢筋笼，铺设预应力钢绞线管道后，通过混凝土进行一次浇筑形成轨道梁主体，所述轨道梁主体的高度低于轨道梁的设计高度；步骤二、轨道梁主体达到规定强度后，张拉钢绞线对轨道梁主体施加预应力；步骤三、在轨道梁主体顶面进行二次浇筑至轨道梁的设计高度，在轨道梁主体表面形成找平层。本发明能够保证跨座式单轨列车轨道梁表面的平整度，提高轨道梁的抗冲击能力。
