冷再生機(jī)水穩(wěn)層施工要注意什么？
來源：http://www.kqj188.com/ 日期：2021-07-05 發(fā)布人：
1、施工放樣應(yīng)在施工前做好施工放樣?；謴?fù)中線時，直線段每15~20m設(shè)一樁，曲線段每10~15m設(shè)一樁，并在兩邊路肩邊沿外設(shè)指示樁，在指示樁上用顯著符號標(biāo)出邊沿的計劃高掛基準(zhǔn)線。
1. Construction lofting should be done well before construction. When restoring the central line, one pile shall be set every 15 ~ 20m in the straight line section and every 10 ~ 15m in the curve section. Besides, indicator piles shall be set outside the shoulder edge on both sides, and the planned high hanging datum line of the edge shall be marked with prominent symbols on the indicator piles.
2、拌和與運送水泥安穩(wěn)碎石底底層選用會合拌制，拌和站設(shè)在百丈互通轉(zhuǎn)盤內(nèi)的空地上。拌和前應(yīng)測定各種規(guī)格的含水量，根據(jù)含水量、天氣情況和運距的長度調(diào)整用水量，保證混合料的含水量均勻、適宜。夏日施工時可先對碎石進(jìn)行灑水濕潤。含水量要比含水量大1.0%，使混合料運到鋪筑地段，攤鋪后在突出時的含水量不小于好值?；覄┝堪凑諛?biāo)準(zhǔn)規(guī)則的檢測頻率和方法進(jìn)行，灰劑量缺乏時要及時加灰，保證灰劑量按大于協(xié)作比0.5％控制并符合技術(shù)標(biāo)準(zhǔn)需要，及時取樣進(jìn)行試件成型
2. Mixing and transporting cement, the bottom layer of Stable Crushed Stone is mixed together, and the mixing station is set in the open space of Baizhang interchange turntable. Before mixing, the water content of various specifications shall be measured, and the water consumption shall be adjusted according to the water content, weather conditions and the length of transportation distance to ensure that the water content of the mixture is uniform and appropriate. In summer, the gravel can be watered first. The water content should be 1.0% higher than the water content, so that the mixture is transported to the paving section, and the water content during rolling after paving is not less than the good value. The ash dosage is carried out according to the detection frequency and method of the standard rules. When the ash dosage is insufficient, the ash should be added in time to ensure that the ash dosage is controlled by more than 0.5% of the collaboration ratio and meets the needs of the technical standards. The sample should be taken in time for the specimen molding
3、側(cè)模板在施工水穩(wěn)層前在硬路肩及沒有計劃路緣石的部位行側(cè)模板支立，防止水穩(wěn)層澆筑施工時水穩(wěn)層澆筑出計劃邊線。側(cè)模支立時要行立模放樣，模板加固后進(jìn)行校模、驗?zāi)?。供認(rèn)模板符合計劃需要并經(jīng)監(jiān)理工程師認(rèn)可，答應(yīng)進(jìn)行水穩(wěn)層澆筑后方可進(jìn)行水穩(wěn)層澆筑施工
3. Before the construction of the water stabilized layer, the side formwork shall be erected on the hard shoulder and the part without planned curb to prevent the water stabilized layer from pouring out of the planned sideline. When the side formwork is erected, the formwork lofting shall be carried out first, and the formwork shall be calibrated and inspected after the formwork is reinforced. It is admitted that the formwork meets the needs of the plan and is approved by the supervision engineer, and the water stable layer pouring construction can be carried out only after the water stable layer pouring is allowed
4、攤鋪在水穩(wěn)層正式開工之前，應(yīng)在監(jiān)理工程師贊同的地址鋪筑長度為100~200米的試驗路段。在鋪筑試驗路段的過程中，應(yīng)設(shè)專人掛線量測，做好調(diào)查和記載，研討、解決發(fā)現(xiàn)的各種疑問。試驗路段應(yīng)在監(jiān)理工程師的監(jiān)督下進(jìn)行，假設(shè)試驗路段經(jīng)監(jiān)理工程師贊同查驗，可作為耐久工程的一有些。
4. Before the construction of water stabilized layer, the test section with a length of 100-200m shall be paved at the address approved by the supervision engineer. In the process of paving the test section, a special person should be assigned to hang up the line for measurement, make investigation and record, discuss and solve various problems found. The test section shall be carried out under the supervision of the supervision engineer. It is assumed that the test section can be used as a part of the durability project after being approved and inspected by the supervision engineer.
如試驗段明顯有些不合格，則將該有些挖除，再進(jìn)行試驗段的試驗至抵達(dá)復(fù)合需要的標(biāo)準(zhǔn)中止現(xiàn)場攤鋪選用兩臺攤鋪機(jī)階梯式聯(lián)合攤鋪工作，攤鋪機(jī)前后相距5~10m，攤鋪速度5km/h。攤鋪過程中應(yīng)根據(jù)拌和才干和運送才干判定攤鋪速度，防止攤鋪機(jī)停機(jī)待料的情況。設(shè)一個三人小組跟在壓路機(jī)后邊， 及時消除粗集料帶或蜂窩，并及時彌補(bǔ)細(xì)混合料，攤鋪平整，嚴(yán)峻部位挖除后用符合需要的混合料添補(bǔ)，挖除深度不小于
If any part of the test section is unqualified, the part shall be excavated, and then the test of the test section shall be carried out until reaching the required standard. The site paving shall be stopped, and two pavers shall be selected for stepped joint paving. The distance between the front and back of the paver shall be 5 ~ 10m, and the paving speed shall be 5km / h. In the paving process, the paving speed shall be determined according to the mixing ability and transportation ability to prevent the paver from stopping for material. Set up a three person team to follow behind the roller, eliminate the coarse aggregate belt or honeycomb in time, make up the fine mixture in time, pave it smoothly, and use the mixture that meets the needs after the severe parts are excavated, and the excavation depth shall not be less than
5、突出（1）、在攤鋪、修整后立即用壓路機(jī)跟在攤鋪機(jī)后在全寬范圍內(nèi)進(jìn)行突出。按靜碾－弱振－強(qiáng)震－靜碾的程序進(jìn)行突出施工，突出施工過程中壓路機(jī)行進(jìn)速度控制在1.5km/h～3km/h（2）、突出程序應(yīng)按試驗路段供認(rèn)的方法施工。突出時，應(yīng)堆疊1/2輪寬，后輪有必要逾越兩段的接縫處。各有些突出到的次數(shù)大概相同，兩邊應(yīng)多壓2~3遍。壓實厚度為15cm，壓路機(jī)突出不到的當(dāng)?shù)赜萌斯ず粚崱?/div>
5. Rolling (1), immediately after paving and finishing, use the roller to follow the paver and roll within the full width. The rolling construction shall be carried out according to the procedure of Static Rolling weak vibration strong vibration static rolling. During the rolling construction, the traveling speed of road roller shall be controlled at 1.5km/h ~ 3km / h (2). The rolling procedure shall be constructed according to the method admitted by the test section. When rolling, 1 / 2 wheel width should be stacked, and the rear wheel is necessary to go over the joint of the two sections. The rolling times of each part are about the same, and the two sides should be rolled 2 ~ 3 times more. The compaction thickness is 15cm, and if the roller can't reach it, it shall be tamped manually.
