4、平面坐标控制点及设计施工图,测放出道路中心线桩及边线桩。管线标志:在道路工程开工前,安排专人认真复核地下管线和地下隐蔽设施的位置和标高,对外露的各种井口设置标志杆牌,以免埋没或堵塞。路基压实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.路基碾压时,应遵循先轻后重、先稳后振、先慢后快、先边后中、先高后低以及轮迹要重叠等原则,且碾压轮应超过分段施工的接缝。2.2.3.2、When compacting road, to first compact stably then 45 times of vibrating compaction last stably compact again.路基压实时先稳压一遍,再振动碾压四五遍,最后再稳压一遍(碾压遍数现场试验后再作调整。2.2.3.3、To compact longitudinally, a

6、nd first edge side them central part.碾压顺道路纵方向进行,且先边后中;轮迹重叠>30cm。2.2.3.4、After compaction, to test compaction coef., through frequency &quantity for quality control.碾压速度均匀,轮迹重叠,压路机碾压不到的部位,应采用小型机夯实或人力夯认真夯实,夯击面在纵横方向均应相互重叠一半,防止漏夯。路基压实后不得有松散、弹簧、翻浆及表面不平整现象,若下层未达到压实度要求,不得铺筑上层。2.2.3.5、Take the soil d

7、ensity test after compaction to judge the quality of the compacted soils.土路基碾压后,按规定频率,数量进行土的密实度试验,以判断碾压质量。进行环刀试验2.3Construction of fly-ash bedding二灰结石的施工:1、The fly-ash will be supplied by as the finished product and delivered on site for paving二灰结石的材料由供货商成品生产后及时运往工地,铺设施工。2、The material mixing scale

8、is strictly comply with the national standard (JTJ034-2000, producing after approval by testing ,材料级配严格按照设计要求进行配合比设计,试验确定后生产执行。配比为: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为: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.在道路基土压实,测试合格进行二灰结石的施工,施工用机械化施工,铺设平整(适当放坡压实密实,严格按规范要求进行。5、Must care for the curing after fly-ash paving, no vehicles pass through during curing period, set barricade for separation.施工完成后的二灰结石,必须确保养期,在保养期内禁止车辆通行,采取道路隔离措施。6、The material inspection w
