碎(sui)石樁的施工質量控制：

質量控制要求：

1、施工(gong)前根據工(gong)藝要求設計進行工(gong)藝性試(shi)樁，不少(shao)于2根，以掌握對(dui)現場的制(zhi)樁經驗及(ji)各種操作(zuo)技術參數。

2、根(gen)據地面高程(cheng)和設計(ji)樁底高程(cheng)的(de)關(guan)系，在套管(guan)上(shang)畫上(shang)設計(ji)深度(du)(du)線，以(yi)保證直觀的(de)觀察到套管(guan)的(de)入土深度(du)(du)。

3、正式施工(gong)時，嚴格按照設計樁長、樁徑、樁間距、碎石(shi)灌入量及試驗確(que)定的樁管提升(sheng)高度、擠(ji)密(mi)次(ci)數(shu)和留振時間、電機工(gong)作電流等施工(gong)參(can)數(shu)進(jin)行施工(gong)，以確(que)保擠(ji)密(mi)均勻(yun)和樁身的連續性。

4、法擠密(mi)應根(gen)據(ju)錘擊的(de)(de)(de)能(neng)量(liang)，控(kong)制分段的(de)(de)(de)填石量(liang)和成樁的(de)(de)(de)長(chang)度。并按貫入(ru)度控(kong)制，保證樁身的(de)(de)(de)連(lian)續性、密(mi)實性及(ji)其(qi)周圍土(tu)層擠密(mi)后的(de)(de)(de)均(jun)勻性。

5、實(shi)際灌(guan)入量沒(mei)有達到(dao)設計用量要(yao)求時，應在原位將樁(zhuang)管打(da)入，補充灌(guan)碎石后復打(da)一次(ci)，或在旁邊補樁(zhuang)一根。樁(zhuang)體在施工中必須確保(bao)連接、密實(shi)。

6、加料按分批加料，侯馬擠密螺紋樁施工，控制(zhi)數量，按少吃多餐(can)原則進行，每段樁體在沒有達到規定(ding)的密實度時須繼續加料振實。

7、拔管速度不得過(guo)快，出碎(sui)石(shi)要(yao)充(chong)分，排(pai)石(shi)不暢時可適當提升提升高度。

8、碎石樁的施工順序應外圍向中間進(jin)行，或(huo)由一邊推向另一邊的方式(shi)施工。

9、樁(zhuang)體(ti)施工完畢后(hou)應將頂部(bu)松散樁(zhuang)體(ti)挖除或(huo)壓(ya)實。

10、碎石樁施(shi)工(gong)完成檢(jian)查(cha)合格且符(fu)合設計(ji)要求后，方可進行下到(dao)工(gong)序(砂礫石墊層(ceng))施(shi)工(gong)。
