水泥稳定碎石施工采用什么施工工艺

来源:/ 日期:2022-09-30
济南水泥稳定碎石施工采用什么施工工艺呢?实际上会采用商品水稳(预拌),用机械摊铺、压路机碾压的施工工艺。下面详细讲下:
What construction technology is used in Jinan cement stabilized macadam construction? In fact, the construction technology of commercial water stabilization (premix), mechanical paving and roller rolling will be adopted. Let's talk about it in detail:
1、原材料基本要求普通硅酸盐水泥、矿渣硅酸盐水泥、火山灰质硅酸盐水泥都可以用于水泥稳定碎石路面基层施工,禁止使用快硬水泥、早强水泥以及其它受外界影响而变质的水泥。
1. Basic requirements for raw materials Ordinary Portland cement, slag Portland cement and pozzolanic Portland cement can be used for the construction of cement stabilized macadam pavement base. Fast hardening cement, early strength cement and other cement deteriorated by external influence are prohibited.
路面基层宜采用强度等级较低的水泥;水泥各龄期强度、安定性等应达到相应指标要求;要求水泥初凝时间3小时以上、终凝时间不小于6小时。
Cement with lower strength grade should be used for pavement base course; The strength and stability of cement at each age shall meet the corresponding index requirements; The initial setting time of cement shall be more than 3 hours and the final setting time shall not be less than 6 hours.
2、水泥稳定碎石施工前准备
2. Preparation before construction of cement stabilized macadam
①本工程水泥稳定碎石基层的下承层为水泥稳定土基层,水泥稳定碎石摊铺须在水泥稳定土达到规定的强度、平整度、拱度等基础上,经验收后,才能进行摊铺。
① The lower bearing layer of the cement stabilized macadam base course of this project is the cement stabilized soil base course. The cement stabilized macadam can only be paved after the cement stabilized soil reaches the specified strength, flatness, camber, etc.
②恢复中线。每10~15m设置一桩,用指示桩标出摊铺宽度。
② Restore the center line. One pile shall be set every 10~15m, and the paving width shall be marked with an indicator pile.
③进行水平测量。在每一断面上设置3个指示桩(即中心桩、左侧边桩和右侧边桩),用明显标记标出水泥稳定碎石基层松铺厚度和设计高程。
③ Carry out level measurement. Set 3 indicator piles (i.e. center pile, left side pile and right side pile) on each section, and mark the loose paving thickness and design elevation of cement stabilized macadam base with obvious marks.

④培肩。为减少水泥稳定碎石混合料在碾压过程中的侧向位移,保证水泥稳定碎石压实度,采取培肩措施,培肩上口宽50cm下口宽70cm,高度不小于水泥稳定碎石压实厚度。为保证雨天排水,可每隔5~10m开挖临时排水沟。
④ Shoulder training. In order to reduce the lateral displacement of cement stabilized macadam mixture during rolling and ensure the compactness of cement stabilized macadam, shoulder training measures are taken. The width of the upper opening of the shoulder is 50cm and the width of the lower opening is 70cm. The height is not less than the compacted thickness of cement stabilized macadam. To ensure drainage in rainy days, temporary drainage ditches can be excavated every 5-10m.
⑤施工前须详细计划安排,尽量减少横向接缝,避免纵向接缝。
⑤ Before construction, detailed planning and arrangement shall be made to minimize transverse joints and avoid longitudinal joints.
