聚酯玻纤布是继土工布、土工格栅、条带聚合物之后发展起来的一种新型复合土工合成材料，与沥青混合料有良好的相容性。工程实践表明，玻纤格栅没有防水功能，其网格能与沥青混合料形成嵌挤作用，但使用中难以固定，易于膨胀而不服贴，影响沥青混合料的正常摊铺和其加筋作用；土工布能防止水下渗，但是土工布在热沥青混合料摊铺温度超过160℃时，其强度和抗蠕变性能较差而无法发挥加筋抗裂效果；而聚酯玻纤布克服了这两者的缺点。它能有效处理路面裂缝以及桥面和路面水损坏。

Polyester glass fiber cloth is a new type of composite geosynthetics developed after geotextile, geogrid and strip polymer. It has good compatibility with asphalt mixture. The engineering practice shows that the glassgrid is not waterproof, the grid can form embed function and asphalt mixture, but difficult to fix, easy expansion and not obedient, affect the normal asphalt mixture paving and its reinforcement effect; geotextile can prevent water infiltration, but the geotextile in hot asphalt paving mixture at the temperature above 160 DEG C, the strength and creep resistance is poor and can not play the anti cracking effect of reinforced polyester fiber; and overcomes the shortcomings of both. It can effectively deal with pavement cracks and bridge and pavement water damage.

钢板止水带即在浇筑下层混凝土时，预埋300mmx3mm的钢板，其中有10-15cm的上部露在外面，在下次再浇筑混凝土时把这部分的钢板一起浇筑进去，起到阻止外面的压力水渗入的作用。一般钢板止水带是采用冷轧板作为母材，因为冷板厚度能够均匀，热板一般厚度达不到均匀的程度，厚度一般为2毫米或者3毫米，长度一般加工成3米长或者6米长，一般为三米好运输。止水钢板对焊接节点要求较高，

In the plate strip pouring bottom concrete, pre buried steel plate of 300mmx3mm, including the upper portion of the 10-15cm exposed, this part of the steel pouring in together again during the pouring of concrete, to prevent the outside pressure of water infiltration effect. General plate sealing strip is made of cold rolled plate as a base material for cold plate thickness can be generally uniform, hot plate thickness is not up to the uniform degree of thickness is 2 mm or 3 mm in length, generally processed into 3 meters long or 6 meters long, three meters generally good transportation. The water stopping steel plate requires higher welding nodes,

不能出现漏点，影响防水性能。

Leakage can not occur, affecting waterproof performance.

Construction points

1、应尽力***止水钢板在墙体中线上；

1, should try to ensure that the steel plate in the wall of the center line;

2、两块钢板之间的焊接要饱满且为双面焊 ，钢板搭接不小于20mm；

The welding between the 2 and two steel plates should be full and double sided welding, and the steel plate shall be lapped not less than 20mm;

3、墙体转角处的处理，一、整块钢板弯折；二、丁字型焊接；三、7字型焊接。

3, the wall corner processing, one, the whole plate bending; two, T-shaped welding; three, 7 type welding.

4、止水钢板的支撑焊接，可以用小钢筋电焊在主筋上；

4 、 the support welding of water stopping steel plate can be welded with small steel bars on the main reinforcement;

5、止水钢板穿过柱箍筋时，可以将所穿过的箍筋断开，制作成开口箍，电焊在钢板上。

5. When the water stopping steel plate passes through the column hoop, the hoop hoop which is crossed can be broken and made into an opening hoop, and the electric welding is arranged on the steel plate.

6、止水钢板的“开口”朝迎水面。

6. The opening of the water stop steel plate faces the water surface.
