改良土施工用到很多设备，下面我们来看一下都用到什么设备：

There are many equipment used in soil improvement construction. Let's take a look at what equipment is used:

就是粉料撒布车，粉料撒布车主要用于公路冷再生施工水泥撒布、路基稳定土多种粘合剂的撒布，也可用于其他场合粉状料的撒布。粉料撒布车是公路现场冷再生施工配套的关键设备，也是路基稳定土施工必须的专用设备，广泛应用于公路及市政建设。粉料撒布车适用于撒布水泥、石灰粉、粉煤灰等粉状物料。

Firstly, there is the powder spreading vehicle. The powder spreading vehicle is mainly used for spreading cement in cold recycling construction on highways, spreading various adhesives for stabilizing soil on roadbeds, and can also be used for spreading powder materials in other occasions. The powder spreading vehicle is a key equipment for cold recycling construction on highway sites, and is also a necessary specialized equipment for stable soil construction of roadbeds. It is widely used in highway and municipal construction. The powder spreading vehicle is suitable for spreading powdered materials such as cement, lime powder, and fly ash.

其次冷再生机，冷再生机实施工艺有什么：对旧路结构状况进行调查，并铺筑试验路，以确定需要再生的深度和新集料的添加量等工艺参数，长度 不宜小于200米；冷再生施工前应将旧路路面清扫干净，并将旧路明显的沉陷、坑槽进行填平处理；人工或机械摊铺添加剂（水泥、石灰、新集料等），按设计的添加量计算每的添加量；冷再生机进行作业。施工过程中，应随时检查深度及速度，以保证再生深度及破碎的混合料级配合理。

Secondly, what is the implementation process of the cold recycling machine? It involves investigating the structural condition of the old road and paving a test road to determine the depth of regeneration required and the amount of new aggregate added, among other process parameters. The length should not be less than 200 meters; Before cold recycling construction, the old road surface should be cleaned up, and obvious subsidence and potholes on the old road should be filled and leveled; Artificial or mechanical paving of additives (such as cement, lime, new aggregates, etc.), with each addition calculated according to the designed amount; The cold regeneration machine is operating. During the construction process, the depth and speed should be checked at all times to ensure that the regeneration depth and the gradation of the crushed mixture are reasonable.

相对于传统的施工方式冷再生机的优势有：成本低，提高旧路等级，不损坏路基，可以不中断交通，工期短，保护环境和资源。

Compared to traditional construction methods, the advantages of cold recycling machines include: low cost, improving the grade of old roads, not damaging the roadbed, not interrupting traffic, short construction period, and protecting the environment and resources.

还有路拌机，稳定土拌和机，是一种自行式全液压稳定土拌和设备，可对二灰土、 二灰碎石、水稳沙砾等各种不同配比材 料进行就地拌和，并可对旧沥青路面进 行铣刨 。行走与拌和转子的驱动均为全液压闭式回路。 行走速度与拌和转子转速均可实现无级变速 辅助系统（转向、拌和转子升降、尾门开闭）均为液压操纵。 通过压力自动补偿装置（POR系统）实现功率自动分配 仪表面板布置合理，显示工作状态 带防翻保护架的密封式驾驶室、豪华型司机座椅，并配带 空调设备，以改善驾驶员的作业环境 低压宽基人字形花纹驱动轮胎，抗振性能优良，附着牵引力大 整体式前桥及SOMA后桥可靠性高 大滚筒工作转子，提高了工作效率，确保了拌和质量，并可根 据用户需要配置水喷洒装置及铣刨转子。

There is also a road mixer, a stabilized soil mixer, which is a self-propelled fully hydraulic stabilized soil mixing equipment. It can mix various materials with different ratios such as fly ash, crushed stone, and water stabilized gravel on site, and can also mill old asphalt pavement. The driving of both the walking and mixing rotors is a fully hydraulic closed circuit. Both the walking speed and the mixing rotor speed can be achieved through a continuously variable transmission auxiliary system (steering, mixing rotor lifting, tailgate opening and closing), all of which are operated by hydraulic pressure. Through the pressure automatic compensation device (POR system), the power automatic distribution instrument panel is arranged reasonably, displaying the working status of the sealed cab with anti rollover protection frame, luxury driver's seat, and equipped with air conditioning equipment to improve the working environment of the driver. The low-pressure wide base herringbone pattern driven tire has excellent anti vibration performance, high adhesion traction force, integrated front axle and SOMA rear axle reliability, and tall drum working rotor, which improves work efficiency and ensures mixing quality. Water spraying device and milling rotor can be configured according to user needs.

还有其它的机器可以从首页观看，在路基开工前，根据工程土类性质和填料性质、压实机械条件，分别选择一定长度的试验区段进行路基填筑试验，以选定与路基填筑、压实、检测有关的工艺参数；改良土配合比等施工工艺参数；确定新的快速试验检测办法与已规定的基本试验检测之间的相互关系等，验证和优化路基填筑施工作业指导书，确定施工工艺参数。

There are other machines that can be viewed from the homepage. Before the comprehensive construction of the roadbed, a certain length of test section is selected for roadbed filling tests based on the properties of the engineering soil, the properties of the filling material, and the conditions of the compaction machinery, in order to select the process parameters related to roadbed filling, compaction, and testing; Improved soil mix ratio and other construction process parameters; Determine the interrelationship between the new rapid testing method and the prescribed basic testing method, verify and optimize the construction operation manual for roadbed filling, and determine the construction process parameters.

试验段的目的是为取得施工经验及相关参数，检验施工机械组合，根据压实机械和路堤不同部位的压实标准来确定松铺厚度、混合料土的含水量、达到设计要求密实度的碾压遍数等，以确定的组合方案。将以上资料整理上报监理工程师批准后，指导此项工程的路基施工。

The purpose of the experimental section is to obtain construction experience and relevant parameters, test the combination of construction machinery, determine the thickness of loose paving, the optimal moisture content of the mixed soil, and the number of rolling passes to achieve the design required compactness based on the compaction standards of different parts of the compaction machinery and embankment, in order to determine the optimal combination scheme. After organizing and submitting the above information to the supervising engineer for approval, guide the roadbed construction of this project.
