路緣石技術交底.doc

交底內容：
1、 本工程道路緣石使用材料是：預制人行道緣石規格為15×30×99.5cm，包括A型立緣石和B型立緣石。車行道部分安裝A型立緣石，人行道部分安裝B型立緣石。
2、 測量放線：
（1） 車行道緣石利用機動車道中6%水泥級配碎石穩定層兩側部分作為基礎墊層，人行道緣石在原地基壓實后作為基礎墊層。
（2） 路面中線校核后，在路面邊緣與緣石交界處放出緣石線，直線部位每10m、曲線部位每5~10m、路口及分隔帶、安全島等圓弧每1~5m設一樁，也可用皮尺畫圓并在樁上標明緣石頂面標高。
3、 刨槽：
按樁的位置打白灰線，以線為準，按設計要求寬度向外刨槽。靠近路面一側，比線位寬出少許，一般不大于5cm。刨槽深度可比設計加深1~2cm，以保證基礎厚度，槽底要修理平整。
4、 鋪筑C10底座砼：
按照設計要求寬度鋪筑緣石C10底座砼厚15cm，，養護3天后方可立緣石。
5、 安裝緣石：
（1）安裝緣石時，先用2cm厚 1：3水泥砂漿找平，再按設計標高安裝緣石。
（2）緣石要安正，切忌前傾后仰，緣石頂線應順直圓滑平順，無凹進凸出前后高低錯牙現象，平。石線要求順直圓滑、頂面平整，符合設計標高要求。
（3）緣石安裝經檢查合格后，即澆筑緣石后座，并振搗
Cards on the table contents:
1, the project road curbs using materials: precast sidewalk curbs specification 15 × 30 × 99.5cm, including the A-and B-Li Yuan Li Yuan Shi Shi. Carriageway part of the installation of A-type legislation curbs, sidewalk part of the installation of B-type legislation curbs.
2, Measure for:
(1) The use of motor vehicle roadway edge of Stone Road, 6% of cement in the stable layer of graded gravel cushion on both sides of part of the basis, the sidewalk edge of the foundation stone in the original basis after compaction cushion.
(2) After checking the road center line, the edge of the road junction with the release of Curb curbs, linear part of each 10m, part of each curve 5 ~ 10m, road junctions and medians, pedestrian refuges arc set one for each 1 ~ 5m, but also available measuring tape marked with a circle and the edge of the stone pile top elevation.
3, the router:
Position by playing white ash pile line to line as, by design width of the outside router. Near the road side, than the line out a little bit wide, generally not more than 5cm. Router design better than the depth of 1 ~ 2cm, to ensure that the basis of the thickness of flat bottom to be repaired.
4, paving concrete base C10:
In accordance with the design width of the paved edge of stone thick concrete base C10 15cm,, conservation of 3 days before the Legislative Yuan Shi.
5, the installation Curb:
(1) When installing curbs, first leveling 2cm thick 1:3 cement mortar, and then design elevation and installation of curbs.
(2) Curb to safety is, should not lean back, margin smooth stone smooth top line to be straight, no indentation protruding teeth before and after the wrong level of the phenomenon, flat. Smooth stone straight line requirement, the top level and meets the design level requirements.
(3) Curb Installation qualified after inspection, that placing the rear edge of stone, and vibration
