硅芯管道的敷设安装应注意以下事项
硅芯管道的敷设安装应注意以下事项:
Attention should be paid to the following items in laying and installing silicon core pipes.
(1)硅芯管道敷设采用人工铺设方式时,应安排足够人力,不得拖地、打扭。
(1) when laying the silicon core pipe by manual laying method, sufficient manpower shall be arranged, and no ground or twisting shall be allowed.
(2)施工前,应先将两端管口严密封堵,防止水、土及杂物等进入管内。
(2) before construction, the ends of both ends should be tightly sealed to prevent water, soil and sundries from entering the pipe.
(3)硅芯管在沟内应平整、顺直布放,地形起伏大、沟坎、转角处应持平、裁直、平缓过渡。
(3) the silicon core tube should be smooth and straight in the ditch, and the terrain should be smooth, straight, and gentle when the terrain is undulating, the ridge and the corner should be straight.
(4)同沟布放多根硅芯管时,应相隔10m左右捆绑一次,各硅芯管的颜色应不同。布放4根以上硅芯管时,采用分两层叠放方式,与光缆同沟布放的隔距不小于10cm,不得重叠、交叉。硅芯管在沟底应松紧适度,在爬坡和转弯处更应注意,在此地段内,硅芯管应每隔50cm用扎带捆扎一次。
(4) when placing many silicon core tubes in the same ditch, it should be bundled around 10m, and the color of each silicon core tube should be different. When placing more than 4 silicon core tubes, the guandaob.89ix.com fengguany.89ix.com jietouw.89ix.com yeyaguan.89ix.com dianxian.89ix.com 400.89ix.comspacing between two channels should be divided into two layers, and the spacing between them should not overlap or overlap. The silicon core pipe should be moderately tight at the bottom of the trench, and should pay more attention to climbing and turning. In this area, the silicon core pipe should be strapped every 50cm.
(5)硅芯管敷设进入(手)孔内的管口应及时封堵;铺设时最小弯曲半径应不小于硅芯管外径的15倍。
(5) the port of the silicon core tube laid into the (hand) hole should be blocked in time; the minimum bending radius should not be less than 15 times the outer diameter of the silicon core tube.
(6)人(手)井间的硅芯管道原则上不采取驳接硅芯管,确因特殊情况需要驳接时,应通知建设单位,由施工单位派技术人员处理,并应采取配套的密封接头件接续,严禁用喷灯直接吹烤硅芯管。驳接后,应进行相应检测,合格后方可覆土,并设置驳接点标石或标志。硅芯管通过河沟时应整条布放,不得驳接。
(6) the silicon core pipe between the human (hand) well does not take the silicon core pipe in principle. In fact, the construction unit should be notified by the construction unit to deal with the technical personnel, and the matching sealing joint should be adopted by the construction unit. After the reconnection, corresponding tests should be carried out. After being qualified, the soil can be covered, and the barcode points or signs should be set up. When the silicon core pipe passes through the river ditch, it should be placed in a whole cloth and must not be barred.
