Grading of the control network平面控制网是土建、钢结构、机电安装、沉降及变形观测施工测量的依据，也是监理等各检测单位复查的基准。布网原则：遵循“从整体到局部，先控制后碎部”的原则。布网要求：各级平面控制点可靠、稳定、使用方

10、便；通视条件好，检校方便，满足施工精度要求。由于该工程量巨大，而且工况复杂，因而必须设置多级平面控制网，而且各级控制网之间必须形成有机的整体。由此本工程建立三级平面控制网。The horizontal control network is the construction surveying basis for civil engineering, steel structures, mechanical and electrical installation, subsidence and deformation observations, and it is also the checki

11、ng benchmark for the supervising unit and other detection units. The principle for setting the network is “From the whole to the part; first control and then smash each part”. The requirements for setting the network are as follows: horizontal control points at all levels should be reliable, stable

12、and easy to use; the points should have good intervisibility, can be checked conveniently and meet the construction accuracy requirements. Due to the large work amount and complex working conditions, multi-level horizontal control networks should be set up and networks at all levels must form an org

13、anic whole. The project sets up a three-level horizontal control network. （1） 首级平面控制网（1） Horizontal control network at the primary level 首级平面控制网是在业主提供的一级坐标点（其坐标见下表）基础上，根据建筑物的总平面定位图，建立一个稳定可靠，不受施工影响的施工控制网。The horizontal control network at the primary level is based on the coordinate points provided by

14、 the proprietor （see the following table）. In line with the general layout positioning map, a reliable construction control network, free from the influence of construction, is established. 该控制网作为首级平面控制网，它是二级平面控制网建立和复核的唯一依据,也是幕墙装修测量、机电安装测量、沉降及变形观测的唯一依据，在整个工程施工期间，必须保证这个控制网的稳定可靠。该控制点的设置位置选择在稳定可靠处，用水泥钢

15、钉打入硬化路面，作为标记，并用红油漆标注。若是未硬化处，要浇注混凝土，并设置保护装置。This network, as the one at the primary level, is the only basis for the establishment of the horizontal control network at the secondary level, checking work, the measurement of curtain wall decoration and mechanical and electrical installation, and the ob

16、servation of subsidence and deformation. In the construction process, the stability and reliability of the control network must be ensured. So the control point should be set at a stable and reliable place. Concrete nails should be driven into the hardened road surface as a mark and the place should

17、 be painted red. In the event that the place is not hardened, concrete should be poured and protective devices should be set. 根据总平面定位图及现场场地实际情况，我们根据坐标点，沿着建筑物周围建立首级平面控制网。依据工程进度定期（结构施工阶段每月一次）对该控制网点进行观测比较，并及时对破坏的控制点进行修复。首级平面控制网如下图：In accordance with the general layout positioning map and the practical

18、situation of the work site, the horizontal control network at the primary level should be established around the buildings based on coordinate points. Based on the progress of the project, observe and compare the control network regularly （once a month in the construction period） and repair the dama

19、ged control points timely. The horizontal control network at the primary level is as shown below in the figure:（2） 二级平面控制网（2） The horizontal control network at the secondary level二级平面控制网的布网以首级平面控制网为依据，布置在施工现场以内相对可靠处，用于为受破坏可能性较大的下一级平面控制网的恢复提供基准，同时也可直接引用该级平面控制网中的控制点测量。二级平面控制网应包括建筑物的主要轴线，并组成封闭图形。The es

20、tablishment is based on the horizontal control network at the primary level. The network at the secondary level should be set up at a relatively reliable place inside the construction site. It is used for providing the basis for the restoring work of the network at the next level that is more likely

21、 to be damaged. In addition, the control points of the network at the secondary level can be used directly for measurement. The horizontal control network at the secondary level should include the main axes of buildings and form a closed figure. （3） 三级平面控制网（3） The horizontal control network at the t

On the third floor, axes are passed vertically by “internal control method” using laser plummet appar

23、atus. On the first and the second floors, “external control method” is used based on the horizontal control network at the secondary level.在首层楼板上，根据施工段平面形状、结构、面积和施工顺序，确定每段布置24个内控点，先施工的第一流水段点位要多，其他流水段点位可减少，但要与先施工的轴线进行联测。所选择的传递点位尽量拉开距离，以保证测量精度，并且点位传递上来后，要能通视。On the first floor, 24 internal control poi

24、nts should be made in each segment in accordance with the plane shape, structure and area of the construction segment, and the construction sequence. The pipeline stage that will be in construction first should have more point locations. Other pipeline stages should have less point locations but sho

27、将激光点调至最小最亮，转动仪器，使激光点在接收靶上形成圆圈，上面操作接收靶人员见光后移动接收靶，使靶交点与圆圈中点重合，此时固定靶位，接收靶中心即控制点位置。投测时测量人员互相之间用对讲机进行联络。First, put the laser plummet at the control points that have already been settled. In the leveling, the instrument emits a laser beam, passing through floor openings and directly going to the laser rec

28、eiving target. The operator of the laser plummet should adjust the laser point to the minimum and the brightest and then turn the instrument, thus making the laser point forming circles on the laser receiving target. Once the operator of the laser receiving target sees the light, he moves the receiv
