混凝土是桥梁工程的主要构成材料。随着桥梁建设事业的不断发展,混凝土的要求量与日俱增。施工中,由于条件的限制,搅拌场与施工现场往往有很大的距离,水平和垂直运输问题给施工带来很大麻烦。首先,在运输中由于颠簸和振动,混凝土产生离析现象,严重影响混凝土质量;其次,在浇注过程中,混凝土通过溜槽,也发生颗粒分离现象,对保证混凝土质量是十分不利的;第三,为了减少运输中的震动,要修路搭桥,弗工弗时,提高成本,延误工期。因此,在桥梁建设中,混凝土的垂直和水平运输问题,成为广大施工人员关切的和急望解决的问题。混凝土输送泵是将混凝土由搅拌机,通过水平或垂直运输,连续输送到浇注地点的一种混凝土输送机械。这种机械在我国使用时间不长,在桥梁建设中,使用也不多。我们在修建丹东沙河口桥时,大胆使用了这种新机械。实践表明,输送泵是混凝土输送的较好机械,是解决混凝土在运输中产生的离析现象,保证混凝土质量的一种施工机具, Concrete is the main constituent material of bridge engineering. With the continuous development of the bridge construction, the demand for concrete is increasing day by day. During the construction, due to the limitation of conditions, the mixing farm often has a great distance from the construction site, and the problems of horizontal and vertical transportation bring great troubles to the construction. First of all, due to the bump and vibration during transport, segregation of concrete occurs, seriously affecting the quality of the concrete. Secondly, during the pouring process, the concrete also passes through the chute and particle separation occurs, which is very unfavorable for ensuring the quality of the concrete. Thirdly, Reduce the vibrations in transport, to build bridges, Epoch time, increase costs, delay the construction period. Therefore, in the bridge construction, the vertical and horizontal transportation of concrete has become a concern and a problem that the construction workers are anxious to solve. Concrete pump is a concrete conveyor that conveys concrete from the mixer to the pouring site through horizontal or vertical transportation. This machine used in our country is not long, in the bridge construction, use is not much. We used this new machine boldly when we built the Dandong Shahekou Bridge. Practice shows that the delivery pump is a better mechanical transmission of concrete is to solve the segregation of concrete produced in the transport to ensure the quality of concrete construction machinery,
