一、適用范圍
1、 Scope of application
冷再生機(jī)出租為保證路床厚度范圍內(nèi)的CBR值和壓實(shí)度達(dá)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(dāng)路基填方高度或挖方深度≤155cm時(shí)，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(zhǔn)備
2、 Homework preparation
1、冷再生施工租賃場地準(zhǔn)備一定必須通過審查簽證；需要進(jìn)行地基處理的基底一定完成各項(xiàng)處理，并滿足地基處理的要求。
1. The preparation of cold recycling construction rental site must pass the examination and visa; The foundation that needs to be treated must be treated and meet the requirements of foundation treatment.
（2）場地應(yīng)該保證足夠的平整度，滿足設(shè)備、人員進(jìn)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(shí)排水和防雨措施。按照施工運(yùn)量和施工機(jī)械的荷載修筑施工便道。
(3) Temporary drainage and rainproof measures should be taken. According to the construction traffic volume and the load of construction machinery, the construction access road is built.
2、技術(shù)準(zhǔn)備
2. Technical preparation
做好相關(guān)人員的技術(shù)培訓(xùn)和技術(shù)交底工作,使參加施工的全體人員充分認(rèn)識(shí)高速鐵路路基填筑的關(guān)鍵技術(shù)、質(zhì)量控制要點(diǎn)。
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(dòng)力、機(jī)械設(shè)備配置
3. Allocation of labor, machinery and equipment
人員、機(jī)械設(shè)備應(yīng)根據(jù)施工方案組合工期要求進(jìn)行合理的配置。路堤填筑區(qū)為一個(gè)完整的作業(yè)區(qū)，每個(gè)作業(yè)區(qū)人員配置：施工隊(duì)長1名，領(lǐng)工員2名，指揮卸土位置人員2名，測量及試驗(yàn)檢測人員4～6人，其他機(jī)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(gè)作業(yè)面配備反鏟挖掘機(jī)一臺(tái)、宣化-140推土機(jī)一臺(tái)、YZ-22振動(dòng)壓路機(jī)兩臺(tái)、天工-160平地機(jī)一臺(tái)，徐工-230灰土拌和機(jī)，自卸運(yùn)輸車6輛，撒水車一臺(tái)備用。當(dāng)運(yùn)距較遠(yuǎn)時(shí)，自卸車的數(shù)量可適當(dāng)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.
