After construction of the additional layer, the waterproofing layer will be re constructed.

四、防水层施工

Four. Waterproof layer construction

7、基础防水层施工

7. Construction of basic waterproof layer

基础防水层施工，卷材搭接宽度长方向统一为100mm，短方向统一为150mm，卷材搭接处有沥青胶溢出。

The construction of basic waterproof layer, the width of the lap lap is 100mm, the short direction is 150mm, and the asphalt overlapped on the lap.

侧壁四周顶部预留防水卷材宽度200mm以上，用于与上部防水层接茬。

The top of the side wall is reserved for waterproofing roll width of 200mm, which is used for the upper waterproofing layer.

做法：向外折翻90·，依附在砖胎膜顶部平面处。

Practice: fold outward 90.

8、承台、底板防水层施工

五、细部构造

Five, detail structure

1、 防水卷材面层施工完成后，用卷材将露出桩头包裹翻起高度20~30mm。火焰温度比正常施工要高些，使卷材充分溢出沥青胶卷材面层施工后，用卷材将桩头四周包严向上翻起20mm~30mm

1. After the construction of waterproofing membrane surface is completed, the exposed pile head will be wrapped up with 20~30mm height. The flame temperature is higher than the normal construction, so that the coil can fully overflow the asphalt film surface. After construction, roll up the pile around the pile head and turn it up 20mm~30mm.
