高速铁路对其预制混凝土箱梁外观提出了比以往更高的要求。为了满足高铁的这些要求,其预制混凝土箱梁在施工中就必须采取一系列的有效措施。从制梁场的选址和布置、预制箱梁的钢模板制安和拆除、预制箱梁的场内移运等方面对高速铁路预制混凝土箱梁外观的质量控制进行简单的介绍和探讨。 High-speed trains put forward higher requirements on the appearance of their precast concrete box girders than ever before. In order to meet these requirements of HSR, a series of effective measures must be taken in the construction of precast concrete box girder. The quality control of appearance of prefabricated concrete box girder of high-speed railway is briefly introduced and discussed from the aspects of siting and layout of the beam making yard, the safety and demolition of the steel formwork of the prefabricated box girder, and the field movement of the prefabricated box girder.
