实施例    1、工程概况 Example 1. Project overview

以某地铁4号线为例,详细介绍支撑挂板使用过程。该地铁4号线某站全长168.8m,地下二层岛式站台。车站主体结构基坑开挖深度17.8m~18.1m,标准段宽度20.5m,扩大端宽度24.4m,共设计上中下3道钢支撑。 Taking a subway line 4 as an example, the use process of the support hanging board is introduced in detail. A station of the Metro Line 4 has a total length of 168.8m and an island platform on the second floor underground. The excavation depth of the foundation pit for the main structure of the station is 17.8m-18.1m, the width of the standard section is 20.5m, and the width of the enlarged end is 24.4m. A total of 3 steel supports are designed, the upper, middle, and lower.

施工期间,为了节约成本,将预埋在冠梁上的钢板变更为挂板式,后来又发展到将钢围檩上的焊接钢板变更为挂板式。经过实际应用后,感觉挂板在施工成本、施工进度方面具有很大作用。 During the construction period, in order to save costs, the steel plate pre-buried on the crown beam was changed to the hanging plate type, and later developed to change the welded steel plate on the steel purlin to the hanging plate type. After practical application, I feel that the hanging board has a great effect on the construction cost and construction progress.

2、实施效果 2. Implementation effect

(1)支撑挂板在钢支撑的应用中,只要防锈工作做好,可以重复使用十几次。本车站长度168.8m,共使用306块挂板,平均每块板60kg,306×60=18360kg,可以有效地降低工程成本。 (1) In the application of steel support, as long as the anti-rust work is done well, the supporting hanging plate can be reused more than ten times. The length of this station is 168.8m, and a total of 306 hanging panels are used, with an average of 60kg per panel, 306×60=18360kg, which can effectively reduce the project cost.

(2)支撑挂板采用工厂加工,使用时只需安装即可,与预埋钢板相比较,施工速度快。 (2) The supporting hanging plate is processed by the factory, and it only needs to be installed when it is used. Compared with the embedded steel plate, the construction speed is fast.
