水泥穩定碎石底基層、基層技術交底記錄.doc

交底內容：
1、路槽驗收
    路槽整理成形后，對壓實度、高程、平整度、寬度、橫坡度等要經監理工程師驗收合格后方可進行下步工序施工。
 2、施工放樣
   采用拓普康全站儀放出控制點，用經緯儀加密，每隔10米打出中心樁和邊樁，在設定樁位處釘設鋼釬，測定高程，掛好施工線。
3、水泥碎石拌和
混合料的拌和采用集中拌和，在正式拌和前，先調試所用的廠拌設備，從表盤、水箱、水泥灌、各下料倉、皮帶輸送機、空壓機、出料倉到各部位線路均調到最佳狀態，然后按試驗配合比進行試拌，確定施工配合比。
4、運輸和攤鋪
（1）、運輸：混合料的運輸一律采用箱板密封良好的10T以上的自卸汽車，其車箱底始終保持潔凈。
（2）、攤鋪：
5、碾壓遍數：先用振動壓路機穩壓2遍，再振壓4遍，再靜壓2遍。
6、養生
水泥碎石碾壓完成后，立即覆蓋草席灑水養護。養生期
Cards on the table contents:
1, Road tank inspection
    Road tank after finishing forming, on the degree of compaction, elevation, roughness, width, cross slope, etc. to acceptance by the Supervising Engineer after the construction process before the next step.
 2, construction setting
   Released by Topcon total station control points, using theodolite encryption, every 10 meters play center and edge pile pile pile is located in the set screw located drill rod, measured height, hang up the construction lines.
3, mixing cement gravel
Mixture mixing centralized mixing, mixing in the official before commissioning the plant mixing equipment used, from the dial, water tanks, cement filling, the lower hopper, belt conveyor, air compressor, a hopper to different parts of lines are transferred to the best condition, and then press the test with the test-mix ratio to determine the construction mix.
4, transport and spreading
(1), transport: transport of mixture shall be sealed with box board for more than a good 10T dump truck, always maintain the cleanliness of their vehicles Bottom.
(2), paving:
5, rolled several times: first with a vibratory roller regulator 2 times 4 times and then vibration pressure, static pressure and then 2 times.
6, health
Rolling Stone after the completion of cement, straw mats covered immediately sprinkler maintenance. Health of
