交底内容：
1、本标段采用排水固结施工的路段约2.25km，排水板采用C型，截面尺寸100×4.5mm，间距1.0~1.6m,梅花形布置，要求打穿软土进入砂层0.5m以上，当软土层超过24.5m时，排水板深度按25m控制,具桩号划分及布置见附图。
2、场地清理完成后，对于一般路段，首先摊铺水平排水砂垫层，接着进行塑料插板施工，而后进行路基施工；对于遇水塘路段，首先砌筑拦水围堰，吹填砂至常水位以上50cm，然后摊铺水平排水砂垫层，进行塑料插板施工。
3、塑料排水板采用套筒式施工，插设完成后的排水板伸出排水垫层20cm.，塑料排水板需要接长时，必须采用滤膜内芯板平搭接的方式，搭接长度不得小于200mm。严格控制回带长度，不得超过500mm,否则要在附近补打，回带的根数应控制在总打设根据数5%以内。
4、塑料排水板在插入地基的过程中应保证排水板不扭曲，透水膜不被撕破和污染。并且排水板底应有可靠的锚固措施，以免在抽出保护套管时，将其带出。
5、塑料排水板插入好后应及时将露出砂垫层的部分切断，并将它保护好，以防因打桩机移动、车辆的进出或者下雨损坏而降低排水效果。
6、施工前塑料排水板应堆放在现场并加以适当的的覆盖以防暴露
Cards on the table contents:
1, the construction of the tenders section of consolidation with drainage of about 2.25km, drain board with C-type, section size 100 × 4.5mm, pitch 1.0 ~ 1.6m, plum-shaped layout, penetrated the soft soil into the sand required more than 0.5m When the soft soil over 24.5m, the drain depth control by 25m, with Stake division and layout, see photos.
2, site clean-up is completed, the general sections, the first level of the drainage paving sand cushion, followed by plastic boards in construction, then for roadbed construction; for the case of reservoir sections, the first masonry to hold water cofferdam, fill sand to constant level over 50cm, and then paving the level of drainage sand cushion, plastic boards for construction.
3, plastic drainage plate with sleeve-type construction, inserted after the completion of the drainage board set out the drainage blanket of 20cm., Plastic drain to pick up a long time, must be used within the core board flat membrane overlapping manner, Lap length not less than 200mm. Strictly control the back with a length of not more than 500mm, or up to fight in the vicinity, back to the root of the number should be controlled with the total number of Installation under 5%.
4, plastic drain board in the insertion process should ensure that the foundation drains are not distorted, permeable membrane is not torn and pollution. And the drain end of the anchorage should be reliable measures to avoid when taking the protection sleeve, brought out.
5, plastic drain into good will come out in time after cutting off part of the sand cushion and protect it to prevent movement due to pile-drivers, vehicle access or rain damage and reduce the drainage effect.
6, before construction of plastic drain board must be put in the scene and make the appropriate coverage to prevent exposure
