高速高鐵路基施工中，路基改良土拌合施工已是常態，路拌機在使用中操作規程如下

In the construction of high-speed railway subgrade, the mixing of subgrade improved soil has become the norm. The operating procedures for the road mixer in use are as follows

一、作業前的準備

1、 Preparation before homework

1.內燃機部分，按通用操作規程的有關規定執行。

1. The internal combustion engine shall be operated in accordance with the relevant provisions of the general operating procedures.

2.詳細了解施工路段的拌和深度、寬度、添加劑量以及其他有關施工技術要求。

2. Gain a detailed understanding of the mixing depth, width, dosage, and other relevant construction technical requirements for the construction section.

3.履帶式拌和機按履帶式機械的規定進行常規檢查與準備。輪胎式拌和機應檢查輪胎是否完好，氣壓是否符合規定要求。

3. The crawler mixer shall undergo routine inspection and preparation according to the regulations for crawler machinery. The tire mixer should check whether the tires are intact and whether the air pressure meets the specified requirements.

4.檢查拌和機的連接部位有無松動情況。

4. Check if the connection parts of the mixer are loose.

5.根據不同的拌和材料，選裝合適的拌和齒。更換拌和齒時，應將轉子升到一定的高度，并用方木墊實，轉子插上保險銷后，方可進行作業。

5. Select suitable mixing teeth according to different mixing materials. When replacing the mixing teeth, the rotor should be raised to a certain height and compacted with square wood. After inserting the safety pin into the rotor, the operation can be carried out.

6.啟動發動機，使轉子空轉進行動態觀察。

6. Start the engine and let the rotor idle for dynamic observation.

二、作業中的要求

2、 Requirements in homework

7.拌和作業時，先將轉子提起，離開地面空轉，再慢慢下降到拌和深度后進行拌和作業。

7. When mixing, first lift the rotor and let it idle off the ground, then slowly lower it to the mixing depth before starting the mixing operation.

8.在拌和過程中，不能急轉彎或原地轉向，遇到底層有障礙物時，應及時提出轉子，并進行檢查和處理。

During the mixing process, it is not allowed to make sharp turns or turn in place. When encountering obstacles at the bottom, the rotor should be promptly removed and inspected and handled.

9.嚴禁使用倒檔進行拌和作業。

9. It is strictly prohibited to use reverse gear for mixing operations.

10.穩定土拌和機在行走和作業過程中，必須保持勻速，作業速度應采用低速。

10. The stabilized soil mixer must maintain a constant speed during walking and operation, and the operating speed should be low.

11.機上各種安全閥不得隨意調節，如損壞失靈，則應進行更換。

11. Various safety valves on the aircraft must not be adjusted arbitrarily. If they are damaged or malfunctioning, they should be replaced.

12.作業時注意液壓油的溫升，不得高于本機規定的正常數值。

12. Pay attention to the temperature rise of hydraulic oil during operation, which should not exceed the normal value specified by the machine.

13.穩定土拌和機進行拌和作業時，操作人員應戴上防塵、防噪聲面具進行作業。

When carrying out mixing operations with a stabilized soil mixer, operators should wear dust and noise masks during the operation.

14.作業時要隨時檢查掌握拌和深度是否達到規定深度，拌和質量是否達到規定要求。

14. During homework, it is necessary to constantly check and master whether the mixing depth has reached the specified depth and whether the mixing quality meets the specified requirements.

15.作業中，操作人員要經常觀察各儀表工作是否正常，機械有無異響，發現故障，應及時停機檢查。

During the operation, the operator should regularly observe whether the instruments are working properly, whether there is any abnormal noise from the machinery, and if any faults are found, the machine should be stopped for inspection in a timely manner.
