吊掛鐵線：首先用紅油漆標出隧道拱頂中間線，在拱頂中間線上沿隧道縱向布設吊掛鐵線，然后從拱頂向兩邊邊墻布設鐵線，間距0.9m（小于吊繩間距10cm），且平行于隧道中線，鐵線兩端布設長度大于屋頂防水板鋪設長度1m。布設鐵線時，先在初期支護面上用沖擊鉆鉆孔，孔眼直徑2cm，深4-5cm，然后楔入木楔。楔入木楔的外端與孔眼齊平。
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.
在木楔上釘釘，把鐵線掛在釘子上后，把鐵釘打彎，以防襯砌混凝土施工時鐵釘刺破屋頂防水板而影響屋頂防水 結果。鐵釘按每2m一根布設，隧道輪廓凸凹不平時，適當加密，以保證鐵線與初期支護密貼。
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.
吊掛屋頂防水板：將屋頂防水板的中間線對準隧道拱頂中間，三至五人站于工作臺架提起屋頂防水板（每人各持一段），將中間線吊繩捆綁于隧道拱頂中間鐵線上，橫向吊繩從拱頂向兩邊邊墻吊掛。悉數掛完后，推動臺架向前移動。同法吊掛第二環、第三環，以至該襯砌一個循環段悉數掛完。屋頂防水板要超前鋪掛，即每一襯砌循環的屋頂防水板鋪掛長度至少比襯砌長度長1m，以便大片屋頂防水板接頭粘接牢靠。
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.
屋頂防水板接頭粘接：屋頂防水板采用搭接粘接，搭接長度10cm。粘接時，首先將屋頂防水板面接頭處擦凈晾干，然后用排刷均勻地刷上粘膠劑。刷膠時，忌往復多次刷，以免底膠“咬”起。涂刷上的膠漿不宜太厚。采用手滾，將屋頂防水板平放于板百度優化，用滾輪車滾壓接頭，至粘接平順牢固為止。
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.
逐段粘接完備個接頭后，將該接頭處用木板加以頂撐，待30分鐘后拆去頂撐。
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.
屋頂防水板的保溫：焊接鋼筋時在其四周用石棉水泥板進行遮擋，以免濺出火花燒壞屋頂防水層。及時灌注砼進行保溫，二次襯砌時，在正對砼輸送管口的屋頂防水板處設置保溫層，避免損壞屋頂防水板。振搗人員經嚴格檢查，杜絕振搗棒點觸屋頂防水板，以免造成破壞。
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.
