4、平面坐標(biāo)控制點(diǎn)及設(shè)計(jì)施工圖,測(cè)放出道路中心線樁及邊線樁。管線標(biāo)志:在道路工程開工前,安排專人認(rèn)真復(fù)核地下管線和地下隱蔽設(shè)施的位置和標(biāo)高,對(duì)外露的各種井口設(shè)置標(biāo)志桿牌,以免埋沒或堵塞。路基壓實(shí)2.2.3.1、When compacting road base, to abide the rules as follows: first light second heavy, first table second vibrate, first slow second quick, first edge second center, first high second low. And compact

5、ion roller should exceed construction joints.路基碾壓時(shí),應(yīng)遵循先輕后重、先穩(wěn)后振、先慢后快、先邊后中、先高后低以及輪跡要重疊等原則,且碾壓輪應(yīng)超過分段施工的接縫。2.2.3.2、When compacting road, to first compact stably then 45 times of vibrating compaction last stably compact again.路基壓實(shí)時(shí)先穩(wěn)壓一遍,再振動(dòng)碾壓四五遍,最后再穩(wěn)壓一遍(碾壓遍數(shù)現(xiàn)場(chǎng)試驗(yàn)后再作調(diào)整。2.2.3.3、To compact longitudinally, a

6、nd first edge side them central part.碾壓順道路縱方向進(jìn)行,且先邊后中;輪跡重疊>30cm。2.2.3.4、After compaction, to test compaction coef., through frequency &quantity for quality control.碾壓速度均勻,輪跡重疊,壓路機(jī)碾壓不到的部位,應(yīng)采用小型機(jī)夯實(shí)或人力夯認(rèn)真夯實(shí),夯擊面在縱橫方向均應(yīng)相互重疊一半,防止漏夯。路基壓實(shí)后不得有松散、彈簧、翻漿及表面不平整現(xiàn)象,若下層未達(dá)到壓實(shí)度要求,不得鋪筑上層。2.2.3.5、Take the soil d

7、ensity test after compaction to judge the quality of the compacted soils.土路基碾壓后,按規(guī)定頻率,數(shù)量進(jìn)行土的密實(shí)度試驗(yàn),以判斷碾壓質(zhì)量。進(jìn)行環(huán)刀試驗(yàn)2.3Construction of fly-ash bedding二灰結(jié)石的施工:1、The fly-ash will be supplied by as the finished product and delivered on site for paving二灰結(jié)石的材料由供貨商成品生產(chǎn)后及時(shí)運(yùn)往工地,鋪設(shè)施工。2、The material mixing scale

8、is strictly comply with the national standard (JTJ034-2000, producing after approval by testing ,材料級(jí)配嚴(yán)格按照設(shè)計(jì)要求進(jìn)行配合比設(shè)計(jì),試驗(yàn)確定后生產(chǎn)執(zhí)行。配比為:熟石灰:粉煤灰:碎石=1:2:33、Lime: cinder: aggregate= 5:15:18三灰碎石混合料配比為:石灰;粉煤灰;集料=5:15:184、The fly-ash paving after road compaction, use machine for construction, leveling, compact

9、ing and sloping, we will strictly fulfill the regulation and code during construction.在道路基土壓實(shí),測(cè)試合格進(jìn)行二灰結(jié)石的施工,施工用機(jī)械化施工,鋪設(shè)平整(適當(dāng)放坡壓實(shí)密實(shí),嚴(yán)格按規(guī)范要求進(jìn)行。5、Must care for the curing after fly-ash paving, no vehicles pass through during curing period, set barricade for separation.施工完成后的二灰結(jié)石,必須確保養(yǎng)期,在保養(yǎng)期內(nèi)禁止車輛通行,采取道路隔離措施。6、The material inspection w
