吊挂铁线：首先用红油漆标出隧道拱顶中间线，在拱顶中间线上沿隧道纵向布设吊挂铁线，然后从拱顶向两边边墙布设铁线，间距0.9m（小于吊绳间距10cm），且平行于隧道中线，铁线两端布设长度大于屋顶防水板铺设长度1m。布设铁线时，先在初期支护面上用冲击钻钻孔，孔眼直径2cm，深4-5cm，然后楔入木楔。楔入木楔的外端与孔眼齐平。
Hanging wire: first with red paint mark in the center line of the tunnel vault, the vault center line along the longitudinal tunnel layout hanging wire, and the wall layout wire to both sides of the edge from the vault, spacing 0.9m (less than 10cm, and the rope spacing) parallel to the tunnel axis, both ends of wire length is greater than the layout of waterproof board laying length 1m. Layout of wire, first with the impact on the primary support surface on the drill hole, the diameter of 2cm, 4-5cm, and wedge wedge. The outer end of the wedge wedge and flush hole.
在木楔上钉钉，把铁线挂在钉子上后，把铁钉打弯，以防衬砌混凝土施工时铁钉刺破屋顶防水板而影响屋顶防水 结果。铁钉按每2m一根布设，隧道轮廓凸凹不平时，适当加密，以保证铁线与初期支护密贴。
A nail on the chocks, the wire hanging on a nail, the nail bending, to prevent the lining concrete construction waterproof board and nail piercing effect of waterproof effect. A nail in each 2m layout, the tunnel contour bump does not usually, appropriate encryption, to ensure a close and initial support.
吊挂屋顶防水板：将屋顶防水板的中间线对准隧道拱顶中间，三至五人站于工作台架提起屋顶防水板（每人各持一段），将中间线吊绳捆绑于隧道拱顶中间铁线上，横向吊绳从拱顶向两边边墙吊挂。悉数挂完后，推动台架向前移动。同法吊挂第二环、第三环，以至该衬砌一个循环段悉数挂完。屋顶防水板要超前铺挂，即每一衬砌循环的屋顶防水板铺挂长度至少比衬砌长度长1m，以便大片屋顶防水板接头粘接牢靠。
Hanging waterproof board: the center line of the tunnel roof waterproof plate alignment center, three to five stations in the work bench bring waterproof board (each holding period), the center line of rope tied to the tunnel center line, horizontal rope from the vault to both sides of the wall hanging. After all finished, push the platform to move forward. With the method of hanging the second, third, and the lining of a circular section after hanging all. Waterproof board should be ahead of the shop, that is, the length of the waterproof board of each lining cycle length of at least longer than the length of the lining 1m, so that a large sheet of waterproof adhesive bonded joints.
屋顶防水板接头粘接：屋顶防水板采用搭接粘接，搭接长度10cm。粘接时，首先将屋顶防水板面接头处擦净晾干，然后用排刷均匀地刷上粘胶剂。刷胶时，忌往复多次刷，以免底胶“咬”起。涂刷上的胶浆不宜太厚。采用手滚，将屋顶防水板平放于板百度优化，用滚轮车滚压接头，至粘接平顺牢固为止。
Waterproof board joint bonding: waterproof board using lap bonding, lap length 10cm. When bonding, the waterproof plate joints wipe dry, and then use the brush evenly on the adhesive. Brush, avoid repeated brush, so as to avoid the bottom glue "bite". The glue coating should not be too thick. The waterproof board is put on the board by hand rolling, and the rolling joint is rolled by the rolling wheel vehicle, and the adhesive is smooth and firm.
逐段粘接完备个接头后，将该接头处用木板加以顶撑，待30分钟后拆去顶撑。
After a section of the integrity of the joint, the joint will be the top of the board to support, to be 30 minutes after the demolition of the top support.
屋顶防水板的保温：焊接钢筋时在其四周用石棉水泥板进行遮挡，以免溅出火花烧坏屋顶防水层。及时灌注砼进行保温，二次衬砌时，在正对砼输送管口的屋顶防水板处设置保温层，避免损坏屋顶防水板。振捣人员经严格检查，杜绝振捣棒点触屋顶防水板，以免造成破坏。
The protection of waterproof boards: welded steel around the asbestos cement plate for shelter, from spark burn waterproof layer. In pouring concrete protection, two lining, the protective layer is arranged at the nozzle on the waterproof plate conveying concrete, avoid waterproof board damage. Vibration personnel by strict training, to prevent the vibration rod point contact with water proof plate phenomenon, so as not to cause damage.
