• Based on the review of recent advances in surveying and controlling techniques of river models , described in this paper is a new controlling technique , which makes use of a two - way axial - flow pump and a immersion pump to control the up - boundary condition of discharge and the down - boundary condition of water level respectively , with the tidal model of the huangpu river estuary as an example
  在对河工模型量测与控制技术进行回顾的基础上，以黄浦江河口潮汐河工物理模型为例，介绍了潮流河段上边界采用轴流泵进行双向流量控制、下边界采用潜水泵进行水位控制的新技术。
• After the investigation and study of this extruded concrete curb solution overseas , shaanxi provincial bureau of water & electric engineering ( group ) co . , ltd . ( spb ) devoted to the research of this new construction method , invented bjy - 40 extrusion curb placing machine , made comprehensive experiments on heihe dam site , and got valuable results , adopted this method in gongboxia hpp main dam construction
  在对国外边墙施工法进行细致调研后，从2001年开始，陕工局率先对这一技术进行研究，研制了bjy - 40型边墙挤压机，在黑河工地进行了现场挤压混凝土边墙和垫层料铺填碾压的综合试验，取得了具有参考价值的第一手资料，并在公伯峡水电站面板坝工程中创新采用了这一技术。
• However , since the contractor has produced a letter from the tung chung rural committee ( tcrc ) , claiming that the materials came from the flood protection project for the stream now underway , the consultant considers that before establishing the " non - legality " of the source , there are difficulties in invoking the terms and conditions of the contract to stop the contractor from transporting such materials to the construction site at its own risk and bearing all consequences and liabilities
  但由于承建商曾出示一份东涌乡事委员会发出的信件，声称石料乃来自进行中的东涌河治河工程，工程顾问表示在未能确定该等石源是非法前，若根据工程合约条款禁止有关承建商在自负所有可能后果及责任的情?下运载石料进入工地，实存在困难。
• During the emergency flood reason , the state flood control headquarters or its authorized flood control headquarters in provinces , autonomous regions and municipalities directly under the central government shall have the right to take emergency measures against bridges , approaches , wharves and other engineering structures across a river which seriously intercept or block water
