1. Cement paving:

根據(jù)結(jié)構(gòu)層的工程量確定水泥用量是必要的，以一米幾袋(技術(shù)員提前算出)為標(biāo)準(zhǔn)，然后在冷再生施工前需要手動攤鋪水泥。，準(zhǔn)備施工部分的水泥，袋裝水泥一般在10米的樁上卸在路邊，在雨季施工時需要準(zhǔn)備防雨布，準(zhǔn)備蓋住。車間前，由施工人員放行施工邊線，用人工灰線圈定結(jié)構(gòu)層的施工范圍，避免水泥車間不到位或浪費(fèi)。在鋪筑時，應(yīng)根據(jù)施工當(dāng)天的天氣情況展開水泥。

It is necessary to determine the cement consumption according to the quantities of the structural layer, taking a few bags per meter (calculated by the technician in advance) as the standard, and then manually pave the cement before the cold regeneration construction. First, prepare the cement for the construction part. The bagged cement is generally unloaded on a 10m pile on the roadside. During construction in rainy season, it is necessary to prepare a rainproof cloth and cover it. Before the workshop, the construction personnel shall release the construction sideline and delineate the construction scope of the structural layer with artificial gray line to avoid the cement workshop not in place or waste. During paving, cement shall be developed according to the weather conditions on the construction day.

現(xiàn)場施工人員將水泥均勻攤開，并注意使每袋水泥的撒布面積相等。水泥撒布完后，表面應(yīng)沒有空白位置，也沒有水泥過于集中的地方。在施工前鋪出150米工作面，然后在冷循環(huán)施工中建造一個150米的水。水泥鋪面總是在冷再生段前150米處。為了減少水泥的過度損耗和施工氣象或機(jī)械故障的突然變化所造成的損壞。

The on-site construction personnel shall spread the cement evenly and pay attention to making the distribution area of each bag of cement equal. After the cement is distributed, there shall be no blank position on the surface and no place where the cement is too concentrated. Lay a 150m working face before construction, and then build a 150m water in the cold cycle construction. The cement pavement is always 150 meters before the cold regeneration section. In order to reduce the excessive loss of cement and the damage caused by the sudden change of construction weather or mechanical failure.

采用水泥稀漿車或粉料撒布車進(jìn)行，改善水泥路面的施工條件。它節(jié)省人工、效率高，均勻污染少。

Cement slurry truck or powder spreader shall be used to improve the construction conditions of cement pavement. It has the advantages of labor saving, high efficiency, uniform and less pollution.

2、冷回?zé)崞鬟\(yùn)行：

2. Operation of cold regenerator:

冷再生機(jī)一次破碎拌合寬度為2.4米。在工作過程中，需要一輛水罐車來跟上操作，以確保水的使用。在混合過程中，根據(jù)試驗表中規(guī)定的適宜含水量1-2%控制水。（前提是需要知道再生機(jī)能打開幾個水噴嘴來換算含水量），另有一輛水罐車需滿水隨時處于待命狀態(tài)。一旦水箱與蓄熱器一起用完，就需要立即填充。保證了連續(xù)工作的持續(xù)作業(yè)能力。

The primary crushing and mixing width of the cold regenerator is 2.4m. During work, a water tanker is required to keep up with the operation to ensure the use of water. In the mixing process, control the water according to the appropriate water content of 1-2% specified in the test table（ The premise is to know that the regenerator can open several water nozzles to convert the water content), and another water tanker needs to be full of water and on standby at any time. Once the water tank is used up with the heat accumulator, it needs to be filled immediately. Ensure the continuous operation ability of continuous work.

冷再生裝置的運(yùn)動速度應(yīng)根據(jù)路面損壞情況和再生深度進(jìn)行調(diào)整，一般為6m/min～12m/min，使材料銑刨后料的級配波動范圍較小。在冷再生的過程中，人們需要隨時隨地檢查混合深度和濕度，一般為20米。

The movement speed of the cold recycling device shall be adjusted according to the pavement damage and recycling depth, generally 6m / min ~ 12m / min, so that the grading fluctuation range of the milled material is small. In the process of cold regeneration, people need to check the mixing depth and humidity anytime and anywhere, generally 20m.

如果不合格，司機(jī)應(yīng)及時反映解決。在各冷再生施工作業(yè)中，振動壓路機(jī)必須遵循冷再生后背20m處，并采用高幅低頻振動及時破碎混合料，速度等于冷再生機(jī)的行車速度。目的在適宜含水率下密封混合料中的水分。

If it is unqualified, the driver shall report and solve it in time. In each cold regeneration construction operation, the vibratory roller must follow the direction of 20m behind the cold regeneration, and use high amplitude and low frequency vibration to crush the mixture in time, with a speed equal to the driving speed of the cold regeneration machine. Objective to seal the moisture in the mixture at an appropriate moisture content.
