底基層混合料拌合
Mixing of subbase mixture
根據(jù)批復(fù)的濟南水穩(wěn)砼底基層配合比確定各種材料的比例,采用拌合機進行拌合。拌合前先檢測場內(nèi)各規(guī)格集料的含水率,并計算當(dāng)天的施工配合比,實際生產(chǎn)配合比的拌和含水率應(yīng)較佳含水率大于0.5%~1%,以補償攤鋪及碾壓過程中的水分損失。
The proportion of various materials shall be determined according to the approved mix proportion of Jinan water stabilized concrete subbase, and the mixer shall be used for mixing. Before mixing, the moisture content of aggregates of various specifications in the site shall be tested first, and the construction mix proportion of the day shall be calculated. The actual production mix proportion shall have a better moisture content of more than 0.5%~1% to compensate for the moisture loss during paving and rolling.
拌和站現(xiàn)場安排兩名試驗人員隨時進行檢測。每天開機后當(dāng)集料輸送帶上的集料達到正常狀態(tài)時,立即從集料帶上截取一段集料進行級配試驗,檢查施工級配配合比是否滿足要求。
Two test personnel shall be arranged at the mixing plant site to conduct inspection at any time. When the aggregate on the aggregate conveyor belt reaches the normal state after starting every day, immediately cut a section of aggregate from the aggregate belt for grading test to check whether the construction grading mix ratio meets the requirements.
正式生產(chǎn)之后,每1-2小時檢查一次拌和情況,檢驗其配合比、含水率、水泥劑量,發(fā)現(xiàn)異常時及時調(diào)整或停止生產(chǎn)。
After formal production, check the mixing condition every 1-2 hours, check the mix ratio, water content and cement dosage, and timely adjust or stop production in case of any abnormality.
拌合時水泥實際用量要比設(shè)計用量稍有增加,且增加值不超過0.5%,以抵消施工強度離散性比設(shè)計強度離散性增大的影響。加水量的計量采用流量計的方式,且流量數(shù)值要在控制室的控制面板上顯示。
The actual cement consumption during mixing is slightly higher than the design consumption, and the increase value is not more than 0.5%, to offset the impact of the increase in the construction strength dispersion than the design strength dispersion. The metering of water addition shall adopt the flow meter, and the flow value shall be displayed on the control panel in the central control room.
在每天施工結(jié)束后要清理干凈,檢查并進行適當(dāng)維護,尤其要注意避免水泥結(jié)塊而堵塞水泥下料口,防止生產(chǎn)過程中混合料水泥劑量偏低,影響基層強度。
Clean up, inspect and maintain properly after the construction every day, especially pay attention to avoid cement caking and blocking the cement blanking port, and prevent the low cement dosage of the mixture in the production process from affecting the strength of the base course.
底基層混合料運輸
Transportation of subbase mixture
運輸采用大噸位自卸汽車,汽車的尾部尺寸符合攤鋪機喂料斗的要求,運輸能力要與拌合樓產(chǎn)量和現(xiàn)場攤鋪能力相匹配。運輸車輛在裝料時應(yīng)派專人指揮前后移動,先裝前部,再裝后部,后再裝中間,防止出現(xiàn)混合料離析現(xiàn)象。
The large-tonnage dump truck shall be used for transportation. The tail size of the truck shall meet the requirements of the paver's hopper. The transportation capacity shall match the production of the mixing plant and the on-site paving capacity. When loading, transport vehicles shall be directed to move forward and backward by specially-assigned person. The front part shall be loaded first, then the rear part, and then the middle part to prevent mixture segregation.
混合料運輸車裝料前應(yīng)清理干凈,車廂不得有雜物。運輸時采用苫布全封閉覆蓋混合料,以防止水分蒸發(fā)及沿途污染。
The mixture transport vehicle shall be cleaned before loading, and the carriage shall be free of sundries. The mixture shall be covered with tarpaulin completely during transportation to prevent water evaporation and pollution along the way.
車輛按規(guī)定線路行駛,不得在養(yǎng)生期間的鋪筑層行使,車輛行走速度不宜太快,保證運輸?;旌狭弦M快運鋪裝現(xiàn)場,保證及時、連續(xù)和。車輛倒車時在攤鋪機前30cm處停住,卸料時掛空擋,注意不要撞擊攤鋪機,不要把料卸在攤鋪機外面。
The vehicle shall be driven according to the specified route and shall not be driven on the pavement during curing. The vehicle shall not travel too fast to ensure transportation safety. The mixture shall be transported to the paving site as soon as possible to ensure timely, continuous and safe. When backing up, the vehicle shall stop 30cm in front of the paver. When unloading, the vehicle shall be in neutral gear. Pay attention not to hit the paver, and do not unload the material outside the paver.
在進入施工區(qū)域的路基坡道口鋪設(shè)草簾及土工布,防止運輸車輛將泥帶入工作區(qū)域,同時安排專人隨時打掃車輪印記,確保下承層及已鋪筑的下基層面干凈。還有什么產(chǎn)品事項了解可以隨時來我們網(wǎng)站http://guixin.net.cn進行咨詢!
The grass curtain and geotextile shall be laid at the roadbed slope crossing entering the construction area to prevent the transport vehicles from bringing mud into the working area. At the same time, special personnel shall be arranged to clean the wheel marks at any time to ensure that the lower bearing layer and the paved lower base surface are clean.
