開塞控制

在(zai)澆混(hun)凝土(tu)后的3~5d，混(hun)凝土(tu)強(qiang)度(du)達到C10~C15時方可進行開塞。開塞時間的早(zao)晚，對注漿較為關鍵。

控制注(zhu)漿時間(jian)是確保順(shun)利注(zhu)漿的(de)(de)重點。開(kai)塞(sai)時間(jian)早(zao)了，混凝土未形(xing)成(cheng)一定的(de)(de)強(qiang)度(du)，在(zai)高壓水的(de)(de)沖射下會破壞(huai)樁端的(de)(de)樁成(cheng)形(xing)和混凝土強(qiang)度(du);過(guo)遲(chi)，包裹注(zhu)漿后(hou)的(de)(de)混凝土強(qiang)度(du)過(guo)大，會造成(cheng)注(zhu)漿頭橡(xiang)膠膜打不開(kai)現(xian)象，使預埋管報廢，終(zhong)不能(neng)注(zhu)漿。開(kai)塞(sai)時要(yao)在(zai)現(xian)場(chang)觀(guan)察高壓注(zhu)漿泵的(de)(de)開(kai)塞(sai)壓力，記錄開(kai)塞(sai)情況，要(yao)寫(xie)明開(kai)啟一根、兩根還是未開(kai)啟。

注漿控制

注漿時應注意相關檢查，只有情況符(fu)合施(shi)工要求，才能確保工程質量。

首(shou)先檢查水(shui)(shui)泥，其不能(neng)有(you)結(jie)塊現象(xiang)。核實進場的(de)(de)(de)(de)水(shui)(shui)泥量(liang)(liang)及水(shui)(shui)泥漿(jiang)(jiang)(jiang)(jiang)(jiang)的(de)(de)(de)(de)水(shui)(shui)灰比(bi)，摻(chan)外(wai)加劑的(de)(de)(de)(de)，檢查外(wai)加劑的(de)(de)(de)(de)摻(chan)量(liang)(liang)。檢查高壓(ya)注(zhu)(zhu)漿(jiang)(jiang)(jiang)(jiang)(jiang)泵的(de)(de)(de)(de)壓(ya)力(li)表、閥(fa)門(men)、管(guan)線完好狀況(kuang)。注(zhu)(zhu)漿(jiang)(jiang)(jiang)(jiang)(jiang)開始記錄注(zhu)(zhu)漿(jiang)(jiang)(jiang)(jiang)(jiang)壓(ya)力(li)。注(zhu)(zhu)漿(jiang)(jiang)(jiang)(jiang)(jiang)壓(ya)力(li)過小，對(dui)樁(zhuang)端土、樁(zhuang)周土加固范(fan)圍滲(shen)入(ru)充填(tian)強度、深(shen)度小，加固作(zuo)用小;注(zhu)(zhu)漿(jiang)(jiang)(jiang)(jiang)(jiang)壓(ya)力(li)過大(da)，可能(neng)會(hui)損(sun)壞注(zhu)(zhu)漿(jiang)(jiang)(jiang)(jiang)(jiang)管(guan)。因此要控(kong)制一(yi)個(ge)較合適的(de)(de)(de)(de)注(zhu)(zhu)漿(jiang)(jiang)(jiang)(jiang)(jiang)壓(ya)力(li)，一(yi)般為開塞(sai)壓(ya)力(li)的(de)(de)(de)(de)一(yi)半。注(zhu)(zhu)漿(jiang)(jiang)(jiang)(jiang)(jiang)一(yi)般以注(zhu)(zhu)入(ru)水(shui)(shui)泥量(liang)(liang)為主控(kong)因素，水(shui)(shui)泥注(zhu)(zhu)入(ru)量(liang)(liang)達(da)(da)到預(yu)(yu)定量(liang)(liang)，無(wu)特(te)殊情(qing)況(kuang)即可停止(zhi)注(zhu)(zhu)漿(jiang)(jiang)(jiang)(jiang)(jiang)。預(yu)(yu)定量(liang)(liang)可根據， 2根的(de)(de)(de)(de)注(zhu)(zhu)漿(jiang)(jiang)(jiang)(jiang)(jiang)情(qing)況(kuang)進行修正。現場監(jian)理(li)人員要記錄每次水(shui)(shui)泥的(de)(de)(de)(de)用量(liang)(liang)，保證水(shui)(shui)泥的(de)(de)(de)(de)注(zhu)(zhu)入(ru)量(liang)(liang)達(da)(da)到要求(qiu)。

滿夯跟強夯施(shi)工有什么不一(yi)樣的地方呢？

滿夯是強夯施工(gong)地基處理(li)中的(de)在其中一(yi)種加(jia)工(gong)工(gong)藝(yi)，一(yi)般(ban)來說滿夯的(de)使用大概可依照下邊(bian)的(de)步驟開(kai)展。

1、主復夯所有(you)工程施工完(wan)畢(bi)以(yi)后，大家會(hui)對不(bu)一樣土層(ceng)開(kai)展區(qu)別，區(qu)分(fen)后的土層(ceng)靜養(yang)時(shi)間也會(hui)不(bu)一樣，須直到孔隙度中的水(shui)清除后，才可以(yi)推行滿(man)夯施工技術。

2、滿(man)夯(hang)(hang)(hang)(hang)關鍵(jian)功(gong)能(neng)于表(biao)(biao)層，這(zhe)兒的(de)表(biao)(biao)層的(de)含(han)意關鍵(jian)指：主夯(hang)(hang)(hang)(hang)擊點高電子(zi)能(neng)級(ji)夯(hang)(hang)(hang)(hang)擊震動造成(cheng)松脫的(de)地表(biao)(biao)層土(tu)。此(ci)外(wai)在開(kai)展(zhan)滿(man)夯(hang)(hang)(hang)(hang)加工工藝進行流程中，其(qi)夯(hang)(hang)(hang)(hang)擊能(neng)通(tong)常是主夯(hang)(hang)(hang)(hang)點夯(hang)(hang)(hang)(hang)擊能(neng)的(de)二分之一(yi)。除(chu)此(ci)之外(wai)通(tong)過滿(man)夯(hang)(hang)(hang)(hang)后的(de)地表(biao)(biao)要加一(yi)遍輾壓。

3、滿夯(hang)的(de)工(gong)程施工(gong)通常(chang)采用四分之一(yi)(yi)的(de)錘徑，開(kai)展雙重鋼筋(jin)(jin)搭接。夯(hang)錘夯(hang)擊的(de)次數、每一(yi)(yi)次點一(yi)(yi)下(xia)的(de)數目及其(qi)鋼筋(jin)(jin)搭接都應當依(yi)照試夯(hang)明確的(de)技術參數來(lai)工(gong)程施工(gong)，需注意(yi)的(de)是不可以發生漏夯(hang)的(de)狀況。

滿夯(hang)(hang)是(shi)對(dui)回(hui)填(tian)土(tu)(tu)后的(de)(de)地土(tu)(tu)壤層采用聯合分布的(de)(de)夯(hang)(hang)實(shi)，并且(qie)是(shi)不可忽略的(de)(de)。因(yin)此它主要是(shi)對(dui)夯(hang)(hang)實(shi)品質的(de)(de)嚴格(ge)管理。殊不知與眾不同的(de)(de)是(shi)強夯(hang)(hang)地基主要是(shi)應用大落(luo)距(ju)、大凈重的(de)(de)夯(hang)(hang)錘(chui)，來夯(hang)(hang)實(shi)回(hui)填(tian)，這也是(shi)一(yi)般夯(hang)(hang)實(shi)加工(gong)工(gong)藝沒法或難以做到的(de)(de)實(shi)際效果(guo)。

滿夯的(de)(de)動能較低，應用低動能夯錘(chui)夯擊，用以(yi)表層。此外落夯點中間互(hu)相密(mi)切排(pai)序，不容易存(cun)有空隙。每擊夯點的(de)(de)間距(ju)距(ju)離(li)為零。它(ta)規定互(hu)壓(ya)或鋼筋搭接錘(chui)印，少(shao)夯很(hen)多(duo)遍。
