1、synchronous backup software does not respond to the rest of the data to be modified. In order to ensure maximum server exception, saving some data, synchronization of real-time backup software should have high, that delay does not exceed 1 minute. Offsite backups that must be supported across networ

2、k segments. In accordance with the above requirements for development our dedicated backup software. After development, wing that opened in salt on high speed test results meet the design requirementsWith the passing of time, it is preparing source Huan of Hubei industrial investment company limited

3、 factory close to the planning of the day looks like, planning human ideals gradually into an entity, spread out before us. Security plan enters the deployed State. After listening to your business objective for the leaders of security, I quickly people with loyalty to the cause of security, as well

4、 as previous security experience, combined with peer pioneers of success stories or experiences. Border security on your business ideas and suggestions to make as follows: 1.1 after careful analysis of a blueprint of the enterprise, taking into account your enterprise factory boundary: 540.65M x 234

5、.24M rectangular site. 1.2 scope for such dachangqu, I recommend the solid border security deployment, for a range of reasons, whether we use infrared radiation, electronic fences, alarm had done there, where the response. Because the factory could not spend a great deal of manpower cost to post thr

6、ee steps, five steps and a whistle. As we all know, under the current form of human resources costs much higher than the cost of all scientific and technological input. In order to better achieve the goal of planners, as well as for Active solid border defense work. We recommend that you use infrare

7、d radiation or linkage of electronic fences with video security deployment to achieve security goals. 1.3 in accordance with the device on the wall of the compound properties and parameters to a reasonable plan to install the infrared radiation equipment or fences and electronic equipment as well as

8、 video surveillance equipment, the specific needs of the equipment and materials quantities we will detail later. 1.4 the programme according to your companys site to see and listen to the leadership proposal, and in accordance with the actual needs of the project, with reference to the relevant int

9、ernational standards and national standards, combined with the experience accumulated by the company engaged in multiple projects, prepare the technology package. If the contents or any other aspect of the programme has not detailed where we welcome your valuable comments. Second, the design princip

10、les of the project design follows technology advanced, functional, stable and cost-saving principles. And considering construction, maintenance and operation, and for future development, expansion, reconstruction and other factors leave room for expansion. Design elements of the system is the system

11、atic, integrated and comprehensive; design has the scientificity, reasonability and operability. Its has following principles: 2.1, and advanced and applicability used currently most advanced of soft, and hardware and the network technology, errors rate low, compatible sex strong, upgrade easy, used

12、 module type structure, expansion convenient, no repeat construction investment, system of technology performance and quality index should reached international leading level; while, system of installation debugging, and software programming and operation using and should simple, easy master, for Ch

13、ina conditions and this project of features. Set the number of advanced technology in a the systems, reflects the current level of the latest development of computer and network technology, adapted to the requirements of the times. While the system is the system used for various management levels, i

15、试桩。西南交通大学硕士研究生学位论文第36页2、打桩顺序打桩顺序即钢管桩先、后打入的顺序,亦称桩机跑位顺序。一般应按下述原则安排钢管桩先、后打入的顺序:(1)桩的入土标高有不同时,应先深后浅;(2)当场地中有重要管道、电缆及其他地下公共设施时,应先打靠近这些设施的桩,使继续打入的桩,逐渐远离己有的设施;(3)当有临近建筑物时,为防止打桩过程中相邻建筑物造成较大位移和变位,应先打近临建筑物的桩,后打的桩逐渐远离建筑物;(4)尽可能先打布桩密集区域的桩;(5)先打长桩后打短桩,先打大直径桩,后打小直径桩的程序进行;(6)在打桩机回转半径范围内的桩宜一次流水施打完毕;(7)业主或设计方的特殊要求。确

16、定打桩顺序后,标出桩心位置,并用石灰撒圈标出桩径大小和位置;标出打桩顺序和桩机走行路线,并在桩机走行路线上铺垫碎石。3、桩的起吊吊钢管桩多采用一点绑扎起吊,待吊到桩位进行插桩,将钢管桩对准事先用石灰划出的样桩位置,作到桩位正,桩身直。一头起吊后,要避免另一头在地面被拖拉,这样容易损伤端部,不利焊接。检查出不符要求的钢桩,要作修整后方可起吊打入。起吊后的桩,对准石灰线插正。对H型桩,有方向性,应注意不能插错。在桩机的正前方和侧方呈直角方向用二台经纬仪观测桩的垂直度,可藉控制导杆的仰俯、桩架的左右摆动,使桩锤、桩帽及桩成一直线,记录员和桩锤操作员就位后,就可打桩。4、打桩钢桩的打入精度与下节桩的就位正确和垂直度密切相关。由于桩、桩帽及桩锤自重较大,一般情况下,下节桩不需锤击(或少量锤击)即会很快沉入土中,这一下沉过程应控制其缓慢进行,待稳定后再行锤击,最初阶段宜使柴油锤处于不燃烧油料的空击状态(犹如自由落锤)。在此期间,要随时跟
