印度创造全球道路摊铺新纪录
2021-09-26 中国工程机械商贸网

一家总部位于印度的建筑承包商帕特尔基础设施公司在铺设31公里长的八车道高速公路期间创造了四项铺路工程世界纪录,并获得了世界纪录组织的认证。

自2021年2月1日开始在24小时内,该公司使用维特根SP 1600摊铺机和一台TCM 180拉毛养生机生产了 14,527.50 立方米的预拌混凝土,使用一台滑模摊铺机单次将其铺设了14,641.43立方米的面积。

这创造了滑模摊铺机24小时内铺设路面质量混凝土最高数量和预拌混凝土站生产的最大的混凝土量的纪录。

该公司使用维特根PS 1600滑模摊铺机进行道路施工,在路段上铺设了48,804.75平方米的刚性路面质量混凝土,创造了24小时内铺设道路最大面积的纪录。

新高速公路由8条车道和硬路肩组成,宽18.75米。这意味着该公司还创造了单台摊铺机在24小时内用一台摊铺机铺设最宽路面和在同一地点摊铺1,280米的记录。

该公司建造的31公里长的公路是一条新的1,350公里长的高速公路的一部分,该高速公路建成后将连接德里、瓦尔道拉和孟买等城市。

改进后的SP 1600摊铺机现在能够摊铺18.75米的宽度。

PS 1600 滑模摊铺机通常可铺设16米的宽度,维特根的工程师针对该项目进行了特殊改造,使其能够铺设18.75米的宽度。维特根还将TCM 180 拉毛养生机扩展到同样的宽度。

据了解,为了能够在如此短的时间内处理如此大量的混凝土,摊铺过程以1.8 米/分钟的平均速度进行。

World records set on new Indian roadway

By Leila Steed

Construction contractor Patel Infrastructure has set four world records for paving works, while working on a new expressway in India.

The India-based company achieved the feat, which was witnessed and validated by the Gold Book of World Records organisation, during the laying of a 31km-long eight lane road.  

Over a single 24-hour period beginning on 1 February, 2021, Platel Infrastructure used Wirtgen’s SP 1600 paver and a TCM 180 texture curing machine to produce 14,527.50m3 of ready mix concrete, laying it over an area of 14,641.43m3 with a single slip form paver.

This set the records for the highest quantity of pavement quality concrete laid by slip form paver machine in 24 hours and for the largest volume of concrete produced by ready mix concrete plants. 

Patel Infrastructure used a Wirtgen PS 1600 slip form paver to carry out the roadworks. The machine was also used to lay 48,804.75m2 of rigid pavement-quality concrete on the road p - setting the record for the largest area ever laid in a 24-hour period for road construction.

Comprising eight vehicle lanes and a hard shoulder, the new expressway measured 18.75m wide. This meant Patel also secrured the record for the widest pavement quantity concrete laid with a single paver machine or 1,280m at a single loCATion in 24 hours.

The 31km stretch of roadway built by Patel Infrastructure forms part of a new 1,350km-long motorway that will, upon completion, connect the cities of Delhi, Vadodara and Mumbai. The new expressway part of the National Highways Authority of India (NHAI) national development project.

Patel Infrastructure’s PS 1600 slip form paver, which normally provides a laying width of 16m, was specially modified to enable the company to lay at a width of 18.75m by Wirtgen’s engineers for the project. 

Wirtgen also extended the TCM 180 texture curing machine to this width.

It said, “In order to be able to process this enormous quantity of concrete in such a short time, the paving process had to be carried out at an average speed of 1.8 m/min.

“Approximately 30,000 dowel bars and tie bars were inserted using the built-in automatic dowel bar inserter (DBI) and the central tie bar inserters (CTBI), providing the structure with the necessary stability and ensuring that the slabs are bonded together properly to withstand traffic loads for many years to come.”
