濟(jì)南水泥穩(wěn)定碎石施工時(shí)要注重什么問題

　　水泥穩(wěn)定碎石成活后遇雨不泥濘，表面堅(jiān)實(shí)，是路面的理想基層材料。因此現(xiàn)在是越來越受歡迎，而且使用的范圍也是愈加廣闊。那么你知道水泥穩(wěn)定碎石施工時(shí)要注重什么問題嗎？

　　Cement stable gravel alive after rain is not muddy, solid surface, is the ideal base material for advanced pavement. So now it is more and more popular, and the scope of use is more and more wide. So what problem should you notice when cement stabilizes macadam construction?

　　檢查底基，復(fù)核控制樁標(biāo)高。水泥穩(wěn)定碎石鋪裝前，應(yīng)將底基層清理干凈，并灑適量水保持濕潤。

　　First check the base and check the elevation of the control pile. Before cement stabilized gravel paving, the base should be cleaned up, and sprinkle the right amount of water to keep wet.

　　混合采用集中工廠混合。工廠攪拌設(shè)備使用前，應(yīng)對使用過的工廠攪拌設(shè)備及各計(jì)量系統(tǒng)進(jìn)行調(diào)試，使混合料的含水量、骨料級配、水泥含量達(dá)到配比要求，使機(jī)器正常運(yùn)行。輸出與所用鋪路的容量一致。

　　Mixing adopts centralized factory mixing. Before using the mixing equipment in the factory, the used mixing equipment and the measurement system should be debugged to make the water content, aggregate gradation and cement content of the mixture meet the proportion requirements and make the machine run normally. The output corresponds to the capacity of the pavement used.

　　攤鋪、碾壓時(shí)，攤鋪系數(shù)在3-5之間，施工中必須貫徹“寧高不低，不刮”的原則，所有施工項(xiàng)目應(yīng)在水泥終凝時(shí)間前完成.滾壓后立即進(jìn)行密實(shí)度測試，如果測試結(jié)果不符合標(biāo)準(zhǔn)，重新滾壓。

　　Paving, rolling, paving coefficient between 3-5, the construction must be carried out in the "rather high not low, not scraping" principle, all construction projects should be completed before the cement final setting time. Compactness test is carried out immediately after rolling. If the test result does not meet the standard, roll again.

　　一般情況下，濟(jì)南水泥穩(wěn)定碎石作業(yè)完成24小時(shí)后，方可鋪設(shè)邊石。與砌筑的時(shí)間間隔不宜過長，否則混合料形成板坯后，板坯會變硬，增加施工難度，敲擊板容易破壞板坯的完整性。平板。

　　Under normal circumstances, Ji 'nan cement stable gravel operation is completed 24 hours after the laying of edge stone. The time interval with masonry should not be too long, otherwise, after the slab is formed by the mixture, the slab will harden, increasing the difficulty of construction, and knocking the slab is easy to destroy the integrity of the slab. The tablet.

　　維護(hù)時(shí)間不少于7天。在此期間，禁止車輛通行。灑水器每天灑水24次，以保持其濕潤。

　　The maintenance duration is no less than 7 days. During this period, no traffic is allowed. Sprinklers are sprayed 2 to 4 times a day to keep them moist.

　　由于水泥穩(wěn)定碎石的施工時(shí)間短，同時(shí)要求一次性達(dá)到質(zhì)量標(biāo)準(zhǔn)，否則成型的板體不容易修整。因此，要加強(qiáng)施工管理，提高施工機(jī)械化程度，形成規(guī)?；?biāo)準(zhǔn)化的作業(yè)方式，輕松滿足水穩(wěn)的施工要求。

　　Due to the short construction time of cement stabilized macadam, at the same time, it is required to meet the quality standard at one time, otherwise the plate body is not easy to repair. Therefore, it is necessary to strengthen construction management, improve the degree of construction mechanization, form a large-scale, standardized operation mode, easily meet the requirements of water stability construction.
