鉆孔灌注樁后注漿(jiang)施工中應何控制。

一、方案審查控制

鉆孔(kong)灌注(zhu)樁后注(zhu)漿技(ji)(ji)術(shu)施(shi)工(gong)，施(shi)工(gong)單(dan)位除了要(yao)編制(zhi)鉆孔(kong)灌注(zhu)樁施(shi)工(gong)方案外，還需編制(zhi)注(zhu)漿技(ji)(ji)術(shu)的專項施(shi)工(gong)方案，提供各(ge)種注(zhu)漿參數。

后(hou)注漿(jiang)技(ji)術是(shi)一種新(xin)技(ji)術，不同的(de)施工單位，因其人員的(de)技(ji)術水平、機械設備(bei)及工程所在地工程土物理力學性質和(he)賦存狀態的(de)不同，選(xuan)擇的(de)參(can)數不盡相同。因此，監理人員要(yao)(yao)依(yi)據(ju)掌握的(de)施工技(ji)術知識、實(shi)際經(jing)驗、相關資料和(he)有(you)關規范(fan)、標準，對(dui)方案選(xuan)取的(de)參(can)數進行認真的(de)審(shen)查。審(shen)核的(de)參(can)數主要(yao)(yao)有(you)：開塞時間(jian)、開塞壓力、注漿(jiang)壓力、注入水泥的(de)預控量(liang)。

二、鉆孔控制

鉆孔控(kong)制(zhi)主要(yao)依據相關規范的要(yao)求(qiu)進行控(kong)制(zhi)。

鉆孔控(kong)制(zhi)主(zhu)要(yao)依據《建(jian)筑地(di)基(ji)基(ji)礎工(gong)程質量施工(gong)驗收規范(fan)》《建(jian)筑樁(zhuang)基(ji)技(ji)術(shu)規范(fan)》的相關要(yao)求和設計規范(fan)進行控(kong)制(zhi)，重點控(kong)制(zhi)孔深、孔徑和垂直度，了(le)解孔壁情況(kuang)(kuang)，山(shan)西擠(ji)密(mi)樁(zhuang)施工(gong)費用多(duo)少(shao)，及時(shi)了(le)解孔內情況(kuang)(kuang)，是否有坍孔、漏水等現象(xiang)，以便在(zai)后注漿施工(gong)時(shi)采取相應的技(ji)術(shu)措施。

強(qiang)夯施工隊(dui)地基處(chu)理前(qian)為什(shen)么(me)要試夯！

隨著雨季的到來(lai)，很多(duo)土(tu)地(di)變成了濕(shi)陷性(xing)(xing)黃土(tu)甚至淤泥。地(di)基(ji)中濕(shi)陷性(xing)(xing)黃土(tu)強夯施工隊處理(li)的測量(liang)方法有哪(na)些(xie)？強夯施工隊在很多(duo)工程中可以用來(lai)處理(li)濕(shi)陷性(xing)(xing)黃土(tu)，因為其(qi)意(yi)在提高地(di)基(ji)承載力，降低土(tu)層(ceng)壓縮性(xing)(xing)。而且這種方法操作非常(chang)方便快捷，節省資(zi)金和投資(zi)資(zi)金，在施工中加固(gu)方面具有明顯的優勢。

濕(shi)陷性黃(huang)土的處(chu)理(li)方(fang)法:

1.處(chu)理(li)濕陷(xian)性(xing)黃土(tu)常用的(de)(de)方(fang)法(fa)有很(hen)多種，如墊層(ceng)(ceng)(ceng)法(fa)、素土(tu)墊層(ceng)(ceng)(ceng)法(fa)、灰土(tu)墊層(ceng)(ceng)(ceng)法(fa)等。這(zhe)(zhe)些(xie)不同(tong)(tong)的(de)(de)方(fang)法(fa)有不同(tong)(tong)的(de)(de)過程。比(bi)如墊層(ceng)(ceng)(ceng)法(fa)，就是對(dui)濕陷(xian)性(xing)黃土(tu)地基進(jin)(jin)行(xing)(xing)局(ju)部或單側處(chu)理(li)，可以處(chu)理(li)的(de)(de)黃土(tu)層(ceng)(ceng)(ceng)厚(hou)度大(da)概在(zai)一到三厘米左右。這(zhe)(zhe)種墊層(ceng)(ceng)(ceng)法(fa)可以根據不同(tong)(tong)的(de)(de)施工(gong)方(fang)法(fa)要(yao)求承載力和增強(qiang)水穩性(xing)。選擇(ze)整體灰土(tu)墊層(ceng)(ceng)(ceng)進(jin)(jin)行(xing)(xing)處(chu)理(li)。

2.另一種方法(fa)是素(su)土(tu)墊層法(fa)。素(su)土(tu)墊層法(fa)是基坑(keng)開挖后(hou)的(de)原(yuan)始圖紙。先用(yong)水(shui)灑(sa)水(shui)濕(shi)潤，然后(hou)選擇一種機械回填，分層回填的(de)方法(fa)。它可以設(she)計高度。與(yu)機械的(de)做工、土(tu)壤的(de)含(han)水(shui)量、鋪土(tu)的(de)厚度等等都有很大的(de)關系。

柱錘沖擴樁法：

 柱(zhu)錘沖擴樁(zhuang)(zhuang)(zhuang)法，通過人工(gong)成(cheng)孔、螺(luo)旋鉆成(cheng)孔、振動沉管成(cheng)孔或柱(zhu)錘沖擊(ji)成(cheng)孔，填(tian)入(ru)碎石、礦渣(zha)、灰(hui)土(tu)(tu)(tu)、水泥(ni)土(tu)(tu)(tu)、渣(zha)土(tu)(tu)(tu)或CFG料等，分層夯擊(ji)，山西(xi)擠密(mi)樁(zhuang)(zhuang)(zhuang)施工(gong)隊，夯擴樁(zhuang)(zhuang)(zhuang)體，擠密(mi)樁(zhuang)(zhuang)(zhuang)間土(tu)(tu)(tu)，形(xing)成(cheng)復合地基(ji)以提高地基(ji)承載(zai)力和減小沉降。

 柱(zhu)錘沖擴樁法，適用(yong)于雜填(tian)(tian)土(tu)(tu)、素填(tian)(tian)土(tu)(tu)、粉土(tu)(tu)、砂土(tu)(tu)、粘(zhan)性(xing)土(tu)(tu)地(di)基等(deng)，因地(di)制宜采(cai)用(yong)適當的成(cheng)孔(kong)工藝、回填(tian)(tian)料(liao)和夯擴工藝。對(dui)地(di)下(xia)水位以下(xia)飽和松軟土(tu)(tu)層，應(ying)通(tong)過現場(chang)試驗確定其適用(yong)性(xing)。地(di)基處理深度不宜超(chao)過6m，復(fu)合(he)地(di)基承載力特(te)征值不宜超(chao)過163KPa。

土、灰土擠密樁法：

 土(tu)(tu)(tu)(tu)、灰(hui)(hui)土(tu)(tu)(tu)(tu)擠(ji)密(mi)樁(zhuang)(zhuang)法(fa)，采用沉(chen)(chen)管法(fa)、爆擴法(fa)、鉆孔法(fa)、掏孔法(fa)和沖擊法(fa)在(zai)地(di)基中(zhong)(zhong)設置土(tu)(tu)(tu)(tu)樁(zhuang)(zhuang)或灰(hui)(hui)土(tu)(tu)(tu)(tu)樁(zhuang)(zhuang)，在(zai)成樁(zhuang)(zhuang)過程中(zhong)(zhong)擠(ji)密(mi)樁(zhuang)(zhuang)間(jian)土(tu)(tu)(tu)(tu)，由擠(ji)密(mi)的樁(zhuang)(zhuang)間(jian)土(tu)(tu)(tu)(tu)和密(mi)實的土(tu)(tu)(tu)(tu)樁(zhuang)(zhuang)或灰(hui)(hui)土(tu)(tu)(tu)(tu)樁(zhuang)(zhuang)形成復(fu)合地(di)基。以提高地(di)基承(cheng)載力和減小沉(chen)(chen)降，同時也可消除濕(shi)陷性(xing)黃土(tu)(tu)(tu)(tu)的濕(shi)陷性(xing)。

 土(tu)(tu)(tu)(tu)、灰(hui)土(tu)(tu)(tu)(tu)擠(ji)密(mi)樁(zhuang)(zhuang)法(fa)，適(shi)用(yong)于地(di)(di)下水(shui)(shui)位以上的(de)(de)濕陷性黃(huang)土(tu)(tu)(tu)(tu)、雜(za)填土(tu)(tu)(tu)(tu)、素填土(tu)(tu)(tu)(tu)等(deng)地(di)(di)基(ji)，山西(xi)擠(ji)密(mi)樁(zhuang)(zhuang)施(shi)工單位，可(ke)處理地(di)(di)基(ji)的(de)(de)深(shen)度為5~15m。當以消(xiao)除地(di)(di)基(ji)土(tu)(tu)(tu)(tu)的(de)(de)濕陷性為為主要目的(de)(de)時，宜選(xuan)用(yong)土(tu)(tu)(tu)(tu)樁(zhuang)(zhuang)擠(ji)密(mi)法(fa)。當以提高地(di)(di)基(ji)土(tu)(tu)(tu)(tu)的(de)(de)承載力或增強其水(shui)(shui)穩性為主要目的(de)(de)時，宜選(xuan)用(yong)灰(hui)土(tu)(tu)(tu)(tu)擠(ji)密(mi)樁(zhuang)(zhuang)法(fa)。當地(di)(di)基(ji)土(tu)(tu)(tu)(tu)的(de)(de)含水(shui)(shui)量大于24%、飽和度大于65%時，不宜選(xuan)用(yong)灰(hui)土(tu)(tu)(tu)(tu)樁(zhuang)(zhuang)擠(ji)密(mi)法(fa)或土(tu)(tu)(tu)(tu)擠(ji)密(mi)樁(zhuang)(zhuang)法(fa)。
