素土擠密樁施工工藝

1、定位放線：

① 坐標投測

依據建設(she)單位提供(gong)的(de)(de)坐標點用全站儀或(huo)GPS進行工程(cheng)定位，在基坑上(shang)邊選擇可保留位置埋設(she)、固定少4個控制點，東西、南北方向各兩個點，并(bing)在基坑底部(bu)施放出樓的(de)(de)四條周邊軸線，打(da)入(ru)木樁并(bing)釘小(xiao)鐵(tie)釘，地面以上(shang)外漏30～50cm。

② 高程投測

依(yi)據建設單位提(ti)供的(de)高程(cheng)控制(zhi)(zhi)點用(yong)水準儀在基(ji)坑(keng)(keng)周(zhou)邊制(zhi)(zhi)定出(chu)(chu)長期(qi)保留的(de)樓的(de)±0.000，依(yi)此(ci)在樓基(ji)坑(keng)(keng)四周(zhou)坑(keng)(keng)壁上釘鋼(gang)筋頭，做出(chu)(chu)基(ji)坑(keng)(keng)高程(cheng)控制(zhi)(zhi)點。

③ 樁位放線

依(yi)據基坑底部四條邊軸線按照圖紙設計樁間距、排距定出樁位，在樁心釘入鐵(tie)釬，并做白灰明(ming)示。

2、擠密樁成孔

成孔施工前(qian)，應先制定出(chu)成孔路線圖，鐵(tie)路灰土樁(zhuang)施工設備租賃，并對所有樁(zhuang)進行編號。

依據(ju)圖紙設計選用(yong)成(cheng)孔(kong)(kong)機械進行施(shi)工，并保(bao)證(zheng)成(cheng)孔(kong)(kong)桿豎(shu)直，對準(zhun)樁心(xin)，在成(cheng)孔(kong)(kong)桿頂端位置用(yong)紅油漆畫(hua)出設計樁深，以(yi)控制成(cheng)孔(kong)(kong)深度滿足設計要求(qiu)。

成(cheng)孔過(guo)程，采用由(you)外(wai)向內，隔排跳打進行(xing)。

鉆(zhan)孔灌注樁后注漿施工(gong)中(zhong)應何控制。

一、方案審查控制

鉆孔(kong)灌(guan)注樁(zhuang)后注漿技術施(shi)工(gong)，施(shi)工(gong)單位除了要編制鉆孔(kong)灌(guan)注樁(zhuang)施(shi)工(gong)方(fang)案(an)外，還(huan)需(xu)編制注漿技術的專(zhuan)項施(shi)工(gong)方(fang)案(an)，提供各種注漿參數。

后(hou)注(zhu)漿技(ji)術是一種新(xin)技(ji)術，不同的施工單位，因(yin)其人員的技(ji)術水(shui)平、機械(xie)設(she)備及工程所在地工程土(tu)物(wu)理力(li)學性質和(he)賦存狀態(tai)的不同，選(xuan)(xuan)擇(ze)的參(can)數不盡相(xiang)同。因(yin)此，監理人員要依據掌握的施工技(ji)術知識(shi)、實際經驗、相(xiang)關(guan)資料和(he)有關(guan)規范、標準，對(dui)方案選(xuan)(xuan)取的參(can)數進行認真的審查。審核的參(can)數主要有：開(kai)(kai)塞(sai)時間、開(kai)(kai)塞(sai)壓力(li)、注(zhu)漿壓力(li)、注(zhu)入水(shui)泥(ni)的預控量。

二、鉆孔控制

鉆孔(kong)控(kong)制(zhi)主(zhu)要依據相關規范的(de)要求進行控(kong)制(zhi)。

鉆(zhan)孔(kong)控制(zhi)主要依據《建筑地基基礎工程質量施工驗收規范》《建筑樁基技(ji)術(shu)規范》的相(xiang)關(guan)要求和設計規范進行控制(zhi)，重(zhong)點控制(zhi)孔(kong)深、孔(kong)徑和垂(chui)直度(du)，了(le)解孔(kong)壁情況，及時(shi)了(le)解孔(kong)內情況，是(shi)否有坍孔(kong)、漏水等現象，以便在后注(zhu)漿(jiang)施工時(shi)采取相(xiang)應的技(ji)術(shu)措施。
