自行式边墙模板台车的研制及在地铁结构工程中的应用

自行式边墙模板台车能够实现在标准断面的地铁车站结构中的精确快速化施工,可大大提高结构边墙施工效率,同时可以保证工程结构的各方面质量。着重对自行式边墙模板台车的组成、设计原理、受力计算及施工操作等几方面进行深入研究。采用自行式边墙模板台车施工达到了预期的目标:1)养护及时且效果好,大大降低了收缩裂缝的产生,减少渗漏点;2)浇筑完成的结构边墙外观质量好,平整度高,无蜂窝麻面、气泡及孔洞等现象;3)操作快捷、方便,便于维修及保养。

Development and Application of Self-propelled Sidewall Formwork Trolley in Construction of Metro Structures

For the sake of the application of the self-propelled sidewall formwork trolley, accurate and rapid construction of Metro structures can be realized, the construction efficiency of the sidewalls can be improved and the quality of the Metro structures can be guaranteed. In the paper, detailed study is made on the components, design principle, stress calctilation and operation of the self-propelled sidewall formwork trolley. Conclusions drawn are as follows： 1 ） Due to the application of the sidewall formwork trolley, timely and effective concrete curing is achieved, which minimizes the shrinkage cracks and water seeping points ; 2） Due to the application of the sidewall formwork trolley, the quality of the sidewall is improved; 3 ） The sidewall formwork trolley discussed is easy in operation and maintenance.
