交底內(nèi)容:
1、 本工程袋裝砂井施工部位為非機(jī)動(dòng)車道、人行道、綠化帶和邊坡,井徑為7cm,其施工間距為1米,正方形布置,具體按照技術(shù)部門繪制的布樁圖進(jìn)行布置。
2、 施工機(jī)械為導(dǎo)管式振動(dòng)打樁機(jī);砂袋用聚丙烯編織袋;砂采用滲水率較高的中、粗砂,含泥量不應(yīng)大于3%。
3、 施工工藝流程如下:
(1)整平原地面(2)攤鋪20cm砂墊層(3)測量放線:用小木樁定出每個(gè)樁位,測出砂墊層面高程(4)機(jī)具對準(zhǔn)樁位(5)打入套管(6)沉入砂袋(7)拔出套管(8)埋砂袋頭
4、 質(zhì)量要求:
(1) 允許偏差

1, the construction of Sand Wick Road construction sites for non-motor vehicles, sidewalks, green belts, and slope, well diameter of 7cm, the construction of distance is 1 meter square layout, specific technology sectors in accordance with plans drawn to pile layout.
2, construction machinery, pipe vibration pile driver; sand bags PP woven bags; sand with water seepage rates are relatively high, the coarse sand, mud content should not exceed 3%.
3, the construction process is as follows:
(1) The whole plain surface (2) Paving 20cm sand cushion (3) measurement and setting: using small wooden blocks set each pile location, measure the level sand pad elevation (4) Pile Alignment equipment (5) into the casing (6) sinking sand bags (7) pull the tube (8) head buried in sand bags
4, quality requirements:
(1) Tolerance
