1、準備下承層
1. Prepare the lower layer
下承層外表應平整、堅實,具有規則的路拱,下承層的平整度和壓實度應契合標準規則。
The surface of the lower layer should be flat and solid, with regular road arches. The flatness and compaction of the lower layer should comply with standard rules.
新完成的底基層或土基,必需按標準規則停止驗收。凡驗收不合格的路段,必需采取措施,使其到達規范后,方可鋪筑水泥改進土層。
Newly completed subbase or soil foundation must be stopped for acceptance according to standard rules. For sections that fail the acceptance inspection, measures must be taken to ensure that they meet the standards before laying cement to improve the soil layer.
2、施工放樣
2. Construction layout
(1)土基上恢復中線,直線段每15~20m設一樁,平曲線段每10~15m設一樁,并在兩側路肩邊緣外設指示樁。
(1) Restore the centerline on the soil foundation, set up one pile every 15-20m for straight sections, and one pile every 10-15m for flat curve sections, and set up indicator piles outside the edges of the shoulders on both sides.
(2)在兩側指示樁上用明顯標志標出水泥穩定土層邊緣的設計高。
(2) Mark the design height of the cement stabilized soil layer edge with clear signs on both sides of the indicator piles.
3、攤鋪土
3. Spreading soil
依據經歷肯定素土松鋪系數為1.25~1.3,采用機械將土平均地攤鋪在預定的寬度上,外表應平整,并有規則的路拱。
Based on experience, the coefficient of loose paving of plain soil is confirmed to be between 1.25 and 1.3. The soil should be evenly spread on the predetermined width using machinery, with a flat surface and regular road arches.
4、灑水悶料
4. Watering and sealing materials
如已整平的土含水量過小,應在土層上灑水悶料。灑水應平均,避免呈現部分水分過多的現象。細粒土應經一夜悶料。
If the moisture content of the leveled soil is too low, water should be sprayed on the soil layer to seal the material. The watering should be evenly distributed to avoid excessive water content in some areas. Fine grained soil should undergo overnight compaction.
