一、適用范圍
1、 Scope of application
冷再生機出租為保證路床厚度范圍內(nèi)的CBR值和壓實度達到規(guī)范要求，全線路床上部36cm厚采用6%水泥土處理。針對低填淺挖路基，當路基填方高度或挖方深度≤155cm時，路床下部44cm厚換填4%的水泥土處理，路床上部36cm厚換填6%水泥土處理。
In order to ensure that the CBR value and compactness within the thickness range of the roadbed meet the specification requirements, the upper part of the roadbed 36cm thick is treated with 6% cement soil. For low filling and shallow excavation subgrade, when the filling height or excavation depth of subgrade is less than or equal to 155cm, 4% of cement soil is replaced with 44cm in the lower part of roadbed, and 6% of cement soil is replaced with 36cm in the upper part of roadbed.
二、作業(yè)準備
2、 Homework preparation
1、冷再生施工租賃場地準備
1. Cold recycling construction rental site preparation
（1）直接填筑的路基基底，施工前一定通過審查簽證；需要進行地基處理的基底一定完成各項處理，并滿足地基處理的要求。
(1) The subgrade base directly filled must pass the examination and visa before construction; The foundation that needs to be treated must be treated and meet the requirements of foundation treatment.
（2）場地應該保證足夠的平整度，滿足設備、人員進場要求。
(2) The site should be smooth enough to meet the requirements of equipment and personnel.
（3）做好場地的臨時排水和防雨措施。按照施工運量和施工機械的大荷載修筑施工便道。
(3) Temporary drainage and rainproof measures should be taken. According to the construction traffic volume and the heavy load of construction machinery, the construction access road is built.

2、技術準備
2. Technical preparation
做好相關人員的技術培訓和技術交底工作,使參加施工的全體人員充分認識高速鐵路路基填筑的關鍵技術、質量控制要點。
Do a good job in the technical training and technical disclosure of relevant personnel, so that all personnel participating in the construction can fully understand the key technology and quality control points of high-speed railway subgrade filling.
3、勞動力、機械設備配置
3. Allocation of labor, machinery and equipment
人員、機械設備應根據(jù)施工方案組合工期要求進行合理的配置。路堤填筑區(qū)為一個完整的作業(yè)區(qū)，每個作業(yè)區(qū)人員配置：施工隊長1名，領工員2名，指揮卸土位置人員2名，測量及試驗檢測人員4～6人，其他機械工、普工20～30人。
Personnel, machinery and equipment should be reasonably allocated according to the requirements of the construction scheme. The embankment filling area is a complete operation area, and the personnel allocation in each operation area is as follows: 1 construction team leader, 2 foreman, 2 personnel commanding the unloading position, 4-6 measurement and test personnel, 20-30 other mechanical workers and general workers.
根據(jù)施工需要，每個作業(yè)面配備反鏟挖掘機一臺、宣化-140推土機一臺、YZ-22振動壓路機兩臺、天工-160平地機一臺，徐工-230灰土拌和機，自卸運輸車6輛，撒水車一臺備用。當運距較遠時，自卸車的數(shù)量可適當增加。
According to the construction needs, each working face is equipped with a backhoe excavator, a xuanhua-140 bulldozer, two yz-22 vibratory rollers, a tiangong-160 grader, a xcmg-230 lime soil mixer, 6 dump trucks, and a sprinkling truck for standby. When the transportation distance is long, the number of dump trucks can be increased appropriately.
