開塞控制

在澆混(hun)凝(ning)土后(hou)的(de)(de)3~5d，混(hun)凝(ning)土強(qiang)度達到C10~C15時方可(ke)進行開(kai)(kai)塞。開(kai)(kai)塞時間(jian)的(de)(de)早晚，對注漿較為關鍵。

控制注(zhu)漿時(shi)間是確保(bao)順利注(zhu)漿的(de)重點(dian)。開(kai)塞(sai)(sai)時(shi)間早了，混(hun)凝土未形成(cheng)一(yi)定的(de)強(qiang)度(du)，在高壓(ya)水的(de)沖射下會破壞樁(zhuang)端的(de)樁(zhuang)成(cheng)形和混(hun)凝土強(qiang)度(du);過(guo)遲(chi)，包(bao)裹注(zhu)漿后的(de)混(hun)凝土強(qiang)度(du)過(guo)大，會造成(cheng)注(zhu)漿頭(tou)橡膠膜打(da)不開(kai)現(xian)(xian)象，使預埋管報廢，終不能注(zhu)漿。開(kai)塞(sai)(sai)時(shi)要在現(xian)(xian)場觀察高壓(ya)注(zhu)漿泵的(de)開(kai)塞(sai)(sai)壓(ya)力，記錄開(kai)塞(sai)(sai)情況(kuang)，要寫明開(kai)啟(qi)一(yi)根(gen)(gen)、兩根(gen)(gen)還是未開(kai)啟(qi)。

注漿控制

注(zhu)漿(jiang)時應注(zhu)意相(xiang)關(guan)檢查，只(zhi)有情(qing)況(kuang)符(fu)合(he)施工要求，才能確保工程質量。

首先(xian)檢查(cha)水(shui)(shui)泥(ni)，其不(bu)能有結塊(kuai)現象。核實進場的(de)水(shui)(shui)泥(ni)量(liang)(liang)(liang)及(ji)水(shui)(shui)泥(ni)漿(jiang)(jiang)(jiang)的(de)水(shui)(shui)灰(hui)比，摻(chan)外(wai)加劑的(de)，檢查(cha)外(wai)加劑的(de)摻(chan)量(liang)(liang)(liang)。檢查(cha)高壓注(zhu)漿(jiang)(jiang)(jiang)泵(beng)的(de)壓力表、閥門、管(guan)線完好狀況。注(zhu)漿(jiang)(jiang)(jiang)開始記(ji)錄(lu)注(zhu)漿(jiang)(jiang)(jiang)壓力。注(zhu)漿(jiang)(jiang)(jiang)壓力過(guo)小，山西(xi)擠密樁(zhuang)基施工聯系方式(shi)，對樁(zhuang)端土、樁(zhuang)周土加固(gu)范圍滲(shen)入(ru)(ru)充填強度、深度小，加固(gu)作(zuo)用小;注(zhu)漿(jiang)(jiang)(jiang)壓力過(guo)大，可能會損壞注(zhu)漿(jiang)(jiang)(jiang)管(guan)。因此要(yao)控制一個較合適(shi)的(de)注(zhu)漿(jiang)(jiang)(jiang)壓力，一般為開塞壓力的(de)一半。注(zhu)漿(jiang)(jiang)(jiang)一般以(yi)注(zhu)入(ru)(ru)水(shui)(shui)泥(ni)量(liang)(liang)(liang)為主控因素(su)，水(shui)(shui)泥(ni)注(zhu)入(ru)(ru)量(liang)(liang)(liang)達(da)到預定(ding)量(liang)(liang)(liang)，無特殊情況即可停止注(zhu)漿(jiang)(jiang)(jiang)。預定(ding)量(liang)(liang)(liang)可根據， 2根的(de)注(zhu)漿(jiang)(jiang)(jiang)情況進行(xing)修正。現場監理人員(yuan)要(yao)記(ji)錄(lu)每次水(shui)(shui)泥(ni)的(de)用量(liang)(liang)(liang)，保證水(shui)(shui)泥(ni)的(de)注(zhu)入(ru)(ru)量(liang)(liang)(liang)達(da)到要(yao)求。

樁基定義

由設(she)置于巖土中(zhong)的樁和(he)與樁頂聯結的承臺(tai)共同組(zu)成的基(ji)礎或由柱與樁直接聯結的單樁基(ji)礎。

注(zhu)：很多人(ren)認為樁(zhuang)基就是指n根樁(zhuang)的共同體（忽略承臺），這(zhe)種(zhong)理解，明(ming)顯是錯誤的。

二(er)、“慣用(yong)”的樁基驗收時間

由上述錯誤認知導致的慣用(yong)樁(zhuang)(zhuang)基(ji)驗收時(shi)間：樁(zhuang)(zhuang)施工(gong)完(wan)成、樁(zhuang)(zhuang)基(ji)承載力和樁(zhuang)(zhuang)身完(wan)整性檢驗合格。

三、樁基劃分

依據(ju)《建(jian)筑工(gong)程(cheng)施(shi)工(gong)質(zhi)量驗收(shou)統一標(biao)準》GB50300-2013，樁(zhuang)(zhuang)基屬于基礎子分(fen)部中的(de)分(fen)項工(gong)程(cheng)。分(fen)為：鋼(gang)(gang)筋混凝土預(yu)制樁(zhuang)(zhuang)、泥(ni)漿護壁(bi)成孔(kong)灌(guan)(guan)注(zhu)樁(zhuang)(zhuang)、長螺旋鉆(zhan)孔(kong)灌(guan)(guan)注(zhu)樁(zhuang)(zhuang)、沉管(guan)灌(guan)(guan)注(zhu)樁(zhuang)(zhuang)、干作業成孔(kong)灌(guan)(guan)注(zhu)樁(zhuang)(zhuang)、鋼(gang)(gang)樁(zhuang)(zhuang)、錨桿靜壓樁(zhuang)(zhuang)。
