(1), mosaic will first geotextiles in land on the ground for sewing stitching, the single width geotextiles splicing in 4-5 meters into the width of 20 meters of geotextile, and according to the design length of cut. And then the winding barrel in laying geotextile, barrel length of 22 meters. Generally the edge sewing edge winding and on both sides with artificial straightening to prevent the geotextile during winding bend folding. And in the exposed end head of geotextile on the installation of a diameter 90cm of the pipe.
(2)、装船主要是将土工布滚桶吊至土工布铺设船的臂架吊环上使其固定。并且将镇压土工布的碎石包一起装入铺设船上。
(2), shipping is mainly arm frame rings geotextile barrels hanging to the geotextiles laying ship at the fixed. And the repression of geotextiles laying gravel pack together into the boat.
(3)铺设定位铺设定位是整个铺设过程中的关键工序，它直接关系到铺设质量的好坏。为了施工快速它必须能够快速且满足全天候要求的定位装置，为此我单位经过长期反复论证，采用国际较为先进的GPS实时差分定位系统。该系统由三台高精度GPS组成。其中一台主要接收卫星信号和发射差分信号。在作业船上设置两台接收机接收卫星信号和差分信号。这些信号同时输入电脑，经过换算确定出精确定位位置。在铺设作业时先设计好计算机操作程序，再在电脑上按设计坐标设定好所需铺设土工布的施工区域，根据每幅土工布的实际尺寸和施工区域布置平面划分每幅土工布的单元格平面施工图，通过计算机屏幕显示船体设定图形和所设定的铺设区单元格的位置姿态，再用4台铰锚机进行移动船位，使船体定位边线和设定单元格铺设区起始边线重合，说明船体已定位准确即可进行铺设作业。
(3) laying positioning positioning is the key process of whole laying laying process, it is directly related to the laying quality. In order to rapid construction, it must be able to quickly and meet the requirements of positioning all-weather device, therefore I unit after a long repeated demonstration, using GPS real time differential international advanced points positioning system. The system consists of three sets of high precision GPS composition. One major receiving satellite signals and transmitting differential signals. In the operation of ship is provided two sets of the receiver to receive satellite signal and differential signal. These signals are simultaneously input the computer, after conversion to determine the precise location position. To design a good computer operation procedures in the paving operation, then on the computer to set the required the laying of the construction area of Geotextiles by design coordinates, according to each geotextile actual dimensions and construction layout of the area divided each geotextile cell construction drawing plane, through the computer screen showing the hull set graphics and set the position and attitude of the laying of cells, and then 4 sets of hinge anchor machine for mobile position, so that the ship positioning edges and set the cell laying starting sideline coincidence, that hull has accurate positioning can be laying operation.
(4)、进行铺设船体定位准确以后，在土工布的露头圆管上安装好锚固锚并预留一定的长度，用绞锚机反向移动铺设船相当于预留长度的距离，抛下锚固锚，然后移至铺设起始位置，开始时有一定的斜度所以移动距离必须算准。放下铺设滚桶至涂面上，如有高差必须以较高点为准，只要观察一下滚桶吊绳的张紧度就可确定桶有无着地，并根据两端吊绳下放的长度就可确定出涂面有无高差。然后移动绞锚机按着设定的铺设区域位置进行水底摊铺，移动时必须四个锚机同时进行，两个拉紧，两个放松，如不同时或走偏必须及时进行调整。因为是动态定位所以在整个移动过程在电脑上都有显示，只要预定的轨迹和铺设路线一致就说明，铺设准确。由于整个摊铺过程是在水下操作，所以对水流和流向的影响极少，为了减少水流和流向的影响在摊铺时尽量采用顺流或逆流方向进行。同时在摊铺过程中每移动2-3米左右的距离必须投抛碎石包或砂包将摊铺的土工布压住，使其不能上浮。当铺至末端时放松滚桶吊索，将铺设船移出铺设区，同时边抛碎石包将船底部分土工布压住然后提升铺设滚桶，整个铺设过程完成。再移动铺设船进行下一幅布的铺设。
(4), the hull after laying of accurate positioning, outcrops in the circle of geotextile tube installed anchorage anchor and set aside a certain length, with anchor capstan reverse mobile laying ship is equivalent to the reservation length distance cast anchor, anchor, and then moved to start laying the starting position, a certain gradient so the mobile distance must be considered quasi. Put down the laying barrel to coated surface, such as a height must be at a higher point as a standard, as long as look at the barrel sling tension can be determined without a barrel, and according to the length of the rope is decentralization can be determined with and without coating surface elevation. Then the mobile anchor capstan to set regional location of laying bottom paving, the mobile must be four anchor machine at the same time, two strain, two relaxation, if not at the same time or deviate must timely adjust. Because it is so dynamic positioning in the whole moving process are displayed on the computer, as long as the predefined trajectory and paved route consistent means, laying accuracy. Because the spreading process is operated under water, so the influence on the flow and the flow of very few, in order to reduce influence of flow and flow in spreading as far as possible the use of concurrent or countercurrent direction. At the same time in the paving process each mobile 2-3 meters distance must be throwing gravel pack sand will be pressed or geotextile paving, so it cannot float. The pawnshop to relax at the end of barrel sling, the laying ship out laying area, at the same time edge polishing and gravel pack will bottom part of geotextiles laying down and then raise the barrel, the laying process is complete. Move the laying ship under a cloth laying.
