人工撒布水泥的施工方法：

　　Construction method of manually spreading cement:

　?、?、水泥用量計算：老路段水泥穩(wěn)定碎石冷再生設(shè)計劑量為5%，密度：2.137 g/cm3   厚度：0.25m 每平米水泥用量：0.25*2.137*0.05*1000=26.7125斤。加寬段水泥穩(wěn)定碎石水泥劑量6%。密度：2.086 g/cm3 厚度0.15m 每平米水泥用量：0.15*2.086*0.06*1000=18.774公斤。

　?、?Calculation of cement dosage: The design dosage for cold recycling of cement stabilized crushed stone in the old road section is 5%, with a density of 2.137 g/cm3 and a thickness of 0.25m. The cement dosage per square meter is 0.25 * 2.137 * 0.05 * 1000=26.7125 pounds. The cement dosage for stabilizing crushed stone in the widened section is 6%. Density: 2.086 g/cm3 Thickness: 0.15m Cement dosage per square meter: 0.15 * 2.086 * 0.06 * 1000=18.774 kilograms.

　?、?、打布水泥方格：半幅寬度為7.2m+4.58m=11.58m?？v向可分2.4*3+2.3*2劃分，根據(jù)每平米水泥用量，老路5%水泥用量布控長度：100/26.7125/2.4=1.56m  即老路5%水泥用量布控為2.4*1.56；老路4.5%水泥用量布控長度：100/24.04125/2.4=1.73m  即老路4.5%水泥用量布控為2.4*1.73；加寬段布控長度:100/18.774/2.3=2.32m；即布控為2.3*2.32。

　?、?Laying cement grid: half width of 7.2m+4.58m=11.58m. Vertically, it can be divided into 2.4 * 3+2.3 * 2 sections. According to the cement consumption per square meter, the length of the old road's 5% cement consumption control is 100/26.7125/2.4=1.56m, which means the old road's 5% cement consumption control is 2.4 * 1.56; The length of the 4.5% cement consumption control for the old road is 100/24.04125/2.4=1.73m, which means that the 4.5% cement consumption control for the old road is 2.4 * 1.73; Widening section control length: 100/18.774/2.3=2.32m; that is, the control length is 2.3 * 2.32.

　?、?、攤鋪水泥：每個方格放足量合格的水泥兩袋，人工拆開封口，用推板刮勻。布水泥段落長度和冷再生銑刨機速度速度相適應(yīng)，一般在冷再生前60-80m，過長水泥將被風(fēng)、或行車產(chǎn)生的氣流刮走而造成損失。

　?、?Laying cement: Place two bags of qualified cement in each square, manually open the seal, and use a push plate to scrape evenly. The length of the cement section is adapted to the speed of the cold recycling milling machine, usually 60-80m before cold recycling. If the cement is too long, it will be blown away by the wind or the airflow generated by the vehicle, causing losses.

　　粉料撒布車的施工方法：

　　Construction method of powder spreading vehicle:

　?、?、水泥運輸車壓力輸入撒布車進(jìn)行裝料。

　?、?The pressure input of the cement transport vehicle is used to load the material into the spreading vehicle.

　?、啤⒃O(shè)定撒布水泥的寬度和厚度。

　　⑵ Set the width and thickness for spreading cement.

　?、?、進(jìn)行全自動均勻撒布。

　　⑶ Perform fully automatic and uniform spreading.
