沖擊碾壓路機(jī)不同于一般的自行式壓路機(jī)，沖擊碾壓路機(jī)是由牽引車帶動(dòng)非圓形輪滾動(dòng)，多邊形滾輪的大小半徑產(chǎn)生位能落差與行駛的動(dòng)能相結(jié)合沿地面對(duì)土石材料進(jìn)行靜壓、搓揉、沖擊的連續(xù)沖擊碾壓作業(yè)，在道路施工中有幾點(diǎn)與一般壓路機(jī)不同的注意事項(xiàng)。下面冷再生機(jī)租賃廠家為您解說(shuō)。

The impact roller is different from the general self-propelled roller. The impact roller is driven by the tractor to roll with non-circular wheels. The potential energy drop generated by the radius of the polygonal roller is combined with the kinetic energy of the driving. The continuous impact roller is used for static pressure, rubbing and impact of the earth rock materials along the ground. There are several points different from the general roller in road construction. The following is the explanation of the cold regenerator rental manufacturer.

1、施工中平地機(jī)、灑水車要配合到位，一次性處理長(zhǎng)度要盡可能大，確保機(jī)車行駛速度，從而保證處理深度。因沖擊碾壓施工工藝對(duì)沖擊面平整度要求比較高，表面平整時(shí)，沖擊碾壓路機(jī)對(duì)各點(diǎn)沖擊力比較均勻，因此在沖擊碾壓前應(yīng)對(duì)原地表進(jìn)行平整，每沖擊6遍后也要及時(shí)對(duì)沖擊后的路基表面進(jìn)行平整。

1. During construction, the leveling machine and sprinkler shall be coordinated in place, and the length of one-time treatment shall be as large as possible to ensure the running speed of the locomotive and ensure the treatment depth. Since the impact rolling construction process requires high flatness of the impact surface, the impact force of the impact roller on each point is relatively uniform when the surface is flat, so the original surface shall be leveled before impact rolling, and the subgrade surface after impact shall be leveled in time after each 6 times of impact.

2、碾壓施工完成后，要用光輪壓路機(jī)再次碾壓，并精平，進(jìn)一步提高表層土的壓實(shí)度。

2. After the rolling construction is completed, the smooth wheel roller shall be used for rolling again and fine leveling to further improve the compactness of the topsoil.

3、沖擊碾壓對(duì)2級(jí)自重濕陷性黃土的壓實(shí)效果比較明顯，大地提高工作效率，降低勞動(dòng)強(qiáng)度，縮短工期降低成本，與傳統(tǒng)設(shè)備相比，沖擊壓實(shí)機(jī)速度快、沖擊力強(qiáng)、影響深度大，可適當(dāng)放寬對(duì)含水量的要求，成本低、工后沉降小。

3. The compaction effect of impact compaction on grade 2 self weight collapsible loess is relatively obvious, which improves the work efficiency, reduces the labor intensity, shortens the construction period and reduces the cost. Compared with the traditional equipment, the impact compactor has fast speed, strong impact force and large impact depth. The requirements on water content can be appropriately relaxed, with low cost and small post construction settlement.

4、沖擊碾壓施工必須保證一定的機(jī)車行駛速度，因此很適合大面積作業(yè)，如果遇到大面積自重濕陷性黃土特殊土路基，采用沖擊碾壓處理實(shí)屬方案。

4. The impact rolling construction must ensure a certain locomotive running speed, so it is very suitable for large-area operation. If a large-area self weight collapsible loess special soil subgrade is encountered, the impact rolling treatment is the preferred scheme.

5、沖擊碾壓的效果與表層的平整度和含水量也有較大關(guān)系。平整度好，表層的含水量接近佳含水量則效果顯著。

5. The effect of impact rolling is also related to the flatness and water content of the surface layer. If the flatness is good and the water content of the surface layer is close to the optimal water content, the effect is remarkable.

6、使用沖擊碾壓路機(jī)時(shí)輪邊與構(gòu)造物應(yīng)有1米的距離，橋涵構(gòu)造物上填土厚度不少于2.5米。

6. When the impact roller is used, there shall be a safe distance of 1m between the wheel edge and the structure, and the filling thickness on the bridge and culvert structure shall not be less than 2.5m.

7、當(dāng)使用沖擊碾壓路機(jī)的補(bǔ)壓振碾達(dá)標(biāo)路床工程的平均沉降量小于3厘米時(shí)，不宜再進(jìn)行沖擊。

7. When the average settlement of the road bed project is less than 3cm after the impact roller is used for the supplementary compaction and vibration rolling, the impact shall not be carried out again.
