高速高鐵路基施工中，路基改良土拌合施工已是常態(tài)，路拌機(jī)在使用中操作規(guī)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(yè)前的準(zhǔn)備

1、 Preparation before homework

1.內(nèi)燃機(jī)部分，按通用操作規(guī)程的有關(guān)規(guī)定執(zhí)行。

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

2.詳細(xì)了解施工路段的拌和深度、寬度、添加劑量以及其他有關(guān)施工技術(shù)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(jī)按履帶式機(jī)械的規(guī)定進(jìn)行常規(guī)檢查與準(zhǔn)備。輪胎式拌和機(jī)應(yīng)檢查輪胎是否完好，氣壓是否符合規(guī)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(jī)的連接部位有無松動(dòng)情況。

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

5.根據(jù)不同的拌和材料，選裝合適的拌和齒。更換拌和齒時(shí)，應(yīng)將轉(zhuǎn)子升到一定的高度，并用方木墊實(shí)，轉(zhuǎn)子插上保險(xiǎn)銷后，方可進(jìn)行作業(yè)。

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(dòng)發(fā)動(dòng)機(jī)，使轉(zhuǎn)子空轉(zhuǎn)進(jìn)行動(dòng)態(tài)觀察。

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

二、作業(yè)中的要求

2、 Requirements in homework

7.拌和作業(yè)時(shí)，先將轉(zhuǎn)子提起，離開地面空轉(zhuǎn)，再慢慢下降到拌和深度后進(jìn)行拌和作業(yè)。

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(zhuǎn)彎或原地轉(zhuǎn)向，遇到底層有障礙物時(shí)，應(yīng)及時(shí)提出轉(zhuǎn)子，并進(jìn)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(yán)禁使用倒檔進(jìn)行拌和作業(yè)。

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

10.穩(wěn)定土拌和機(jī)在行走和作業(yè)過程中，必須保持勻速，作業(yè)速度應(yīng)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(jī)上各種安全閥不得隨意調(diào)節(jié)，如損壞失靈，則應(yīng)進(jìn)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(yè)時(shí)注意液壓油的溫升，不得高于本機(jī)規(guī)定的正常數(shù)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(wěn)定土拌和機(jī)進(jìn)行拌和作業(yè)時(shí)，操作人員應(yīng)戴上防塵、防噪聲面具進(jìn)行作業(yè)。

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

14.作業(yè)時(shí)要隨時(shí)檢查掌握拌和深度是否達(dá)到規(guī)定深度，拌和質(zhì)量是否達(dá)到規(guī)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(yè)中，操作人員要經(jīng)常觀察各儀表工作是否正常，機(jī)械有無異響，發(fā)現(xiàn)故障，應(yīng)及時(shí)停機(jī)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.
