4、平面坐標控制點及設計施工圖,測放出道路中心線樁及邊線樁。管線標志:在道路工程開工前,安排專人認真復核地下管線和地下隱蔽設施的位置和標高,對外露的各種井口設置標志桿牌,以免埋沒或堵塞。路基壓實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,應遵循先輕后重、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.路基壓實時先穩(wěn)壓一遍,再振動碾壓四五遍,最后再穩(wěn)壓一遍(碾壓遍數(shù)現(xiàn)場試驗后再作調(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,壓路機碾壓不到的部位,應采用小型機夯實或人力夯認真夯實,夯擊面在縱橫方向均應相互重疊一半,防止漏夯。路基壓實后不得有松散、彈簧、翻漿及表面不平整現(xiàn)象,若下層未達到壓實度要求,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)量進行土的密實度試驗,以判斷碾壓質量。進行環(huán)刀試驗2.3Construction of fly-ash bedding二灰結石的施工:1、The fly-ash will be supplied by as the finished product and delivered on site for paving二灰結石的材料由供貨商成品生產(chǎn)后及時運往工地,鋪設施工。2、The material mixing scale

8、is strictly comply with the national standard (JTJ034-2000, producing after approval by testing ,材料級配嚴格按照設計要求進行配合比設計,試驗確定后生產(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,測試合格進行二灰結石的施工,施工用機械化施工,鋪設平整(適當放坡壓實密實,嚴格按規(guī)范要求進行。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
