在施工工况比较复杂的地区，无论是压路还是压地基，都要先把地面弄平一些，这样才能便于压路机这些机械开展下面的压实流程。针对平整这个工作，一种实用的机械设备应运而生，这便是冷再生机租赁厂家今天所要介绍的平地机。

In areas with complex construction conditions, both road and foundation compaction, it is necessary to level the ground first, so as to facilitate the following compaction process for such machines as road rollers. For the work of leveling, a practical mechanical equipment has emerged, which is the grader that the cold recycling machine rental manufacturer will introduce today.

平地机是指利用刮刀平整地面的一种高速、、高精度和多用途的土方工程机械。刮刀装在机械前后轮轴之间，能升降、倾斜、回转和外伸。动作灵活准确，操纵方便，平整场地有较高的精度，适用于构筑路基和路面、修筑边坡、开挖边沟，也可搅拌路面混合料、扫除积雪、推送散粒物料以及进行土路和碎石路的养护工作。

Land leveler refers to a high-speed, efficient, high-precision, and multi-purpose earthwork machinery that uses a scraper to level the ground. The scraper is installed between the front and rear axles of the machine and can be lifted, tilted, rotated, and extended. Flexible and accurate movement, convenient manipulation, and high accuracy in leveling the site. It is suitable for constructing subgrade and pavement, constructing slopes, excavating side ditches, mixing pavement mixtures, removing snow, pushing bulk materials, and maintaining dirt and gravel roads.

公路路基，是路面的基础，是公路工程的重要组成部分。路基承受由路面传来的交通荷载，是路面的支承结构物，它必须具有足够的强度、稳定性和耐久性。根据地形的不同，公路路基一般采用路堤和路堑两种形式。

Highway subgrade is the foundation of pavement and an important component of highway engineering. The roadbed bears the traffic load transmitted from the road surface, and is the supporting structure of the road surface. It must have sufficient strength, stability, and durability. According to different landforms, highway subgrade generally adopts two forms: embankment and cutting.

平地机有如下两个主要作用：

The grader has the following two main functions:

1、将道路横坡刮到符合设计要求。

1. Scrape the cross slope of the road to meet the design requirements.

2、按照道路纵坡的要求，将路面刮到平整。

2. Scrape the road surface to a level surface according to the requirements of the longitudinal slope of the road.

为了将路面刮平，就要求操作人员注意以下几点：

In order to smooth the road surface, the operator is required to pay attention to the following points:

1、机器一定严格按照道路纵向轴线的平行方向行驶；

1. The machine must travel strictly in parallel to the longitudinal axis of the road;

2、严谨边刮便于扭转方向；

2. Strict edge scraping facilitates reversing direction;

3、要根据前轮经过的起伏情况适时调整刮刀高度，尤其前轮经过没有覆盖的雨水井、污水井等的时候，更要降低速度、调整刮刀，避免前轮猛然降低而使得被刮路面形成凹坑；

3. Adjust the height of the scraper according to the undulation of the front wheel. Especially when the front wheel passes through uncovered rainwater wells, sewage wells, etc., it is necessary to reduce the speed and adjust the scraper to prevent the front wheel from suddenly lowering and causing pits on the scraped road surface;

4、要根据机器经过横断面横坡状况适时调整刮刀横向角度，使得横坡符合设计要求；

4. Adjust the lateral angle of the scraper according to the cross section and cross slope conditions of the machine, so that the cross slope meets the design requirements;

5、对于一刀不能完全覆盖的路面，好沿着同一个方向，有中间向两边往复推进，每刀之间要有交叉；

5. For roads that cannot be completely covered by one knife, it is best to push back and forth in the same direction from the middle to both sides, with intersections between each knife;

6、对于较厚处的刮平，要有耐心，一层一层逐渐刮到设计高度，避免一次性下刀太多，这样往往会造成刮面粗糙，甚出现大的凹坑。

6. For scraping thicker parts, it is necessary to be patient and gradually scrape one layer at a time to the design height to avoid too many one-time cuts, which often leads to rough scraping surfaces and even large pits.

平地机可以完成公路重要内容场、农田等大面积的地面平整和挖沟、刮坡、推土、排雪、疏松、压实、布料、拌和、助装和开荒等工作。是矿山建设、道路修筑、水利建设和农田翻土、平整工作等施工中的重要设备。您有需求随时联系我们！
