泰国巴帕南工程水工建筑物设计与施工特点

Characteristics of Hydr aulic Str uctur e Design and Constr uction of Pak Phanang Project in Thailand

泰国巴帕南水闸及附属建筑物工程包括大型防潮水闸、鱼梯和鱼道、引河渠道、截流坝、船闸、排水涵闸、进场和区内公路、永久房建等水工建筑物,电气工程有遥测系统、控制系统、电力系统、电话及火灾报警系统等,为巴帕南流域开发项目的龙头工程,也是一座大型综合利用水利枢纽工程该工程的旋喷桩工程量为同类单项工程世界之最,厢形壳体结构闸门(20m×9.0m)采用单机双吊点启闭的布置,流域河系降雨、水位、闸门位置测量应用先进的遥测系统,这些技术的应用在我国同类水利工程实践中绝无仅有该枢纽布置、底板与闸墩混凝土施工及温度控制。

The Pak Phanang diversion dam and appurtenant structures are composed of the large-scale sluice for tide prevention,fish ladder,fish way,diversion cannel,closure dam,navigation lock,drainage culvert,access roads and M&O buildings.Its electric works include the tele-metering system,control system,power system,telecommu-nication and fire alarming system.It is the most important project in the Pak Phanang River Basin Development Pro-ject and a large-scale multi-purpose water control project.Some technologies adopted in this project are rarely seen in the similar projects in China,such as the box steel gates with two lifting points lifted by one hoist,and measurement of rainfall/water level/gate position by tele-metering system.The quantity of jet grouted piles in this project is the largest in the world.This paper introduces main characteristics,including the general layout of the project,concrete construc-tion and temperature control for the base plate and pier,design and construction for jet grouted piles.
