該發明涉(she)及現澆混凝土鉆孔(kong)灌注樁施(shi)工。
背景技術:
1、樁(zhuang)(zhuang)基(ji)(ji)中(zhong)鋼筋(jin)籠(long)與(yu)樁(zhuang)(zhuang)中(zhong)心偏(pian)(pian)位(偏(pian)(pian)心)數值要控(kong)制(zhi)在5cm以內,在實際施工中(zhong),由(you)于(yu)(yu)各種要素的(de)疊加,會出現(xian)(xian)嚴重的(de)超(chao)標現(xian)(xian)象,即,會出現(xian)(xian)樁(zhuang)(zhuang)基(ji)(ji)中(zhong)鋼筋(jin)籠(long)與(yu)樁(zhuang)(zhuang)中(zhong)心偏(pian)(pian)位數值遠大于(yu)(yu)5cm的(de)情況,這屬于(yu)(yu)施工質(zhi)量不合(he)格。
2、根據偏(pian)位(wei)(wei)位(wei)(wei)置的(de)(de)不(bu)同,又可以分為整(zheng)體偏(pian)位(wei)(wei)和局部(bu)(bu)偏(pian)位(wei)(wei),其中(zhong)(zhong)的(de)(de)整(zheng)體偏(pian)位(wei)(wei)現(xian)象是指,鋼(gang)筋(jin)籠(long)的(de)(de)中(zhong)(zhong)心軸向(xiang)與樁(zhuang)孔中(zhong)(zhong)心軸向(xiang)自上而下整(zheng)體發(fa)(fa)生(sheng)偏(pian)位(wei)(wei),參考圖1。局部(bu)(bu)偏(pian)位(wei)(wei)是指,僅僅鋼(gang)筋(jin)籠(long)的(de)(de)下半段發(fa)(fa)生(sheng)偏(pian)位(wei)(wei)。這兩(liang)種偏(pian)位(wei)(wei)的(de)(de)發(fa)(fa)生(sheng),都會嚴(yan)重的(de)(de)影響樁(zhuang)基的(de)(de)承載能(neng)力。
3、經過分(fen)析(xi),影(ying)響樁(zhuang)基中(zhong)鋼(gang)筋籠與樁(zhuang)中(zhong)心偏位超標(biao)的原(yuan)因包括:
4、(1)、鋼筋籠入樁孔(kong)后初始定位不(bu)精確。
5、(2)、澆筑過程中(zhong)鋼筋(jin)籠上浮并水平移(yi)位,造成施(shi)工中(zhong)的位置(zhi)改變(bian)。
6、現有的鉆孔灌注(zhu)樁(zhuang)鋼(gang)(gang)筋籠(long)(long)(long)居(ju)中(zhong)定位技(ji)術,僅僅能(neng)夠保(bao)證(zheng)鋼(gang)(gang)筋籠(long)(long)(long)在(zai)入樁(zhuang)初期的居(ju)中(zhong)滿足要(yao)求(qiu),即,在(zai)鋼(gang)(gang)筋籠(long)(long)(long)下(xia)方的過程中(zhong),保(bao)證(zheng)樁(zhuang)基中(zhong)鋼(gang)(gang)筋籠(long)(long)(long)與樁(zhuang)中(zhong)心的一致性(xing)滿足規范要(yao)求(qiu),沒有解決(jue)澆筑過程中(zhong)鋼(gang)(gang)筋籠(long)(long)(long)上浮并水平移位而造成的鋼(gang)(gang)筋籠(long)(long)(long)位置(zhi)改變問題。
7、例如,cn218204334u公開了一(yi)種建筑(zhu)工程施工用(yong)鋼(gang)(gang)筋(jin)(jin)(jin)籠(long)(long)定(ding)(ding)(ding)位(wei)裝置(zhi)(zhi),裝置(zhi)(zhi)底座的頂部(bu)設(she)(she)置(zhi)(zhi)有左定(ding)(ding)(ding)位(wei)卡(ka)(ka)箍(gu)(gu)(gu)和(he)右(you)定(ding)(ding)(ding)位(wei)卡(ka)(ka)箍(gu)(gu)(gu),所(suo)述(shu)左定(ding)(ding)(ding)位(wei)卡(ka)(ka)箍(gu)(gu)(gu)和(he)右(you)定(ding)(ding)(ding)位(wei)卡(ka)(ka)箍(gu)(gu)(gu)的兩端均(jun)分別(bie)固定(ding)(ding)(ding)連(lian)接有連(lian)接部(bu),所(suo)述(shu)連(lian)接部(bu)的內部(bu)設(she)(she)有緊固螺(luo)栓,所(suo)述(shu)左定(ding)(ding)(ding)位(wei)卡(ka)(ka)箍(gu)(gu)(gu)和(he)右(you)定(ding)(ding)(ding)位(wei)卡(ka)(ka)箍(gu)(gu)(gu)內部(bu)均(jun)分別(bie)螺(luo)紋連(lian)接有調節螺(luo)桿。本實用(yong)新型通(tong)過(guo)左定(ding)(ding)(ding)位(wei)卡(ka)(ka)箍(gu)(gu)(gu)、右(you)定(ding)(ding)(ding)位(wei)卡(ka)(ka)箍(gu)(gu)(gu)以及(ji)與鋼(gang)(gang)筋(jin)(jin)(jin)籠(long)(long)接觸的弧形(xing)限位(wei)夾塊和(he)限位(wei)滾輪等(deng)的配合可對鋼(gang)(gang)筋(jin)(jin)(jin)籠(long)(long)起到一(yi)定(ding)(ding)(ding)的防偏定(ding)(ding)(ding)位(wei)作用(yong),使(shi)鋼(gang)(gang)筋(jin)(jin)(jin)籠(long)(long)較好(hao)地被限定(ding)(ding)(ding)在該裝置(zhi)(zhi)內,避免(mian)鋼(gang)(gang)筋(jin)(jin)(jin)籠(long)(long)下(xia)放過(guo)程中出現較大晃動(dong)偏移。
