利用冷再生機(jī)施工有哪些優(yōu)勢特點(diǎn)？
來源：http://www.kqj188.com/ 日期：2021-12-14 發(fā)布人：
1.低成本
1. Low cost
道路就地冷再生機(jī)因為所有利用了舊的路面起模原材料，進(jìn)而降低了道路檢修或更新改造時舊起模原材料的基坑開挖、運(yùn)送、廢置和新型材料的購買，進(jìn)而造成成本費(fèi)大幅降低。選用道路就地冷再生比傳統(tǒng)式方法對比，伴隨著再生層薄厚的不一樣，能夠 控制成本，冷再生路面薄厚越厚，控制成本越多。如05年吉林省線磐石段改建工程的施工，經(jīng)經(jīng)濟(jì)發(fā)展技術(shù)性互斥計劃方案較為后，選用混凝土冷再生施工加工工藝開展道路農(nóng)村基層的再生利用，節(jié)省項目投資近43%。
The road local cold recycling machine uses all the old road formwork raw materials, which reduces the foundation pit excavation, transportation, waste and purchase of new materials during road maintenance or renewal, resulting in a significant reduction in cost. Compared with the traditional method, the local cold regeneration of the road can control the cost with the difference of the thickness of the regeneration layer. The thicker the thickness of the cold regeneration pavement is, the more the control cost is. For example, in the construction of the reconstruction project of Panshi section of Jilin Provincial Railway in 2005, after the technical mutual exclusion plan scheme of economic development is relatively, the cold recycling construction and processing technology of concrete is selected to carry out the recycling of rural road base, saving nearly 43% of the project investment.
再生薄厚為27cm，再生層工程預(yù)算為42元/m2，而選用傳統(tǒng)手工藝，需雙層水穩(wěn)加固，加上原路面原材料需消除外調(diào)，工程造價為73元/m2，此后例中由此可見冷再生技術(shù)性可使工程成本大幅度降低。
The thickness of the recycled layer is 27cm, and the budget of the recycled layer project is 42 yuan / m2. However, the traditional handicraft is selected, which needs double-layer water stability reinforcement. In addition, the external transfer of raw materials of the original pavement needs to be eliminated, and the project cost is 73 yuan / M2. In the following example, it can be seen that the cold recycling technology can greatly reduce the project cost.
在路面農(nóng)村基層因其原料的再利用可節(jié)約很多項目投資，在低級別路面中，因用冷再生加工工藝可提升路面農(nóng)村基層級別而減少整體面層的資金投入，這類客觀性具體優(yōu)勢的存有是促使就地冷再生技術(shù)性遭受認(rèn)可而且獲得迅速發(fā)展趨勢的原始動力。
In the rural base course of pavement, the reuse of its raw materials can save a lot of project investment. In the low-level pavement, the use of cold regeneration processing technology can improve the level of rural base course of pavement and reduce the capital investment of the overall surface course. The existence of such objective specific advantages is the original power to promote the recognition of in-situ cold regeneration technology and obtain the rapid development trend.
2.效率高
2. High efficiency
道路就地冷再生機(jī)械設(shè)備施工一次性能夠 進(jìn)行瀝青道路、粉碎、加上、攪拌及鋪筑，進(jìn)而簡單化了施工程序流程，減少施工施工期。應(yīng)用就地冷再生機(jī)械設(shè)備，每日施工可進(jìn)行平米的勞動量。
The construction of road local cold recycling machinery and equipment can carry out asphalt road, crushing, addition, mixing and paving at one time, which simplifies the construction procedure and reduces the construction period. The local cold regeneration mechanical equipment shall be applied, and the daily construction can carry out the labor volume of square meters.
3.受氣溫標(biāo)準(zhǔn)危害小
3. Little harm from temperature standard
舊地冷再生可以在氣溫自然環(huán)境不確定性的標(biāo)準(zhǔn)下施工，除開在降水量很大時，一般的變幻無常的氣溫，毛毛雨氣溫，冷再生機(jī)均可施工，即便在暴雨之后，也可立刻修復(fù)施工。
The cold regeneration of old land can be constructed under the standard of uncertain temperature and natural environment. Except for the general changeable temperature, drizzle temperature and cold regeneration machine when the precipitation is large, the cold regeneration machine can be constructed. Even after the rainstorm, it can be repaired immediately.
4.對城市公共交通危害明顯降低
4. The harm to urban public transport is significantly reduced
冷再生租用施工的特性是冷再生工藝流程簡潔明了，施工設(shè)備少，對交通出行影響體現(xiàn)不比較敏感全部冷再生機(jī)械設(shè)備組成能夠 處在同一條行車道內(nèi)，不危害另一條行車道機(jī)動車行駛，可開展敞開式施工，非常適用車流量很大或路寬窄小狀況下的道路的施工。當(dāng)?shù)缆钒敕┕r，另半幅仍舊啟用，進(jìn)而大大的改進(jìn)施工情況下的交通條件。因而，做為一種效率高、環(huán)保節(jié)能、環(huán)境保護(hù)道路檢修方式和新技術(shù)新工藝，路面冷再生機(jī)早已變成國際性上道路更新改造的關(guān)鍵方式之一。
The characteristics of cold regeneration rental construction are that the cold regeneration process is simple and clear, there are few construction equipment, and it is not sensitive to the impact on traffic. All cold regeneration machinery and equipment can be located in the same traffic lane without endangering the driving of motor vehicles in another traffic lane. Open construction can be carried out, which is very suitable for road construction under the condition of large traffic flow or narrow road width. When half of the road is constructed, the other half is still used, which greatly improves the traffic conditions under construction. Therefore, as a road maintenance method and new technology with high efficiency, environmental protection, energy conservation and environmental protection, pavement cold recycling machine has long become one of the key ways of road renewal and transformation in the world.
5.施工性價比高
5. High construction cost performance
就地冷再生施工能夠 依據(jù)不一樣道路舊起模原材料的具體情況開展設(shè)計方案，挑選不一樣的防腐劑，能夠 確保再生原材料的品格和施工品質(zhì)，產(chǎn)生施工成形厚而勻稱的粘接層，進(jìn)而確保了檢修后道路的應(yīng)用限期。如青縣一機(jī)廠及滄州市東外環(huán)、吉林省202線工程項目(摻入混凝土使用量為6%)全部再生道路再生層的七天無側(cè)限抗拉強(qiáng)度均做到3Mpa之上。一般冷再生層的瀝青混合料選用來源于原貌路面構(gòu)造的瀝青道路料RAP，其冷再生層的點(diǎn)評關(guān)鍵根據(jù)其抗壓強(qiáng)度來操縱，其抗壓強(qiáng)度依路面級別的不一樣由技術(shù)部來明確，七天無側(cè)限抗拉強(qiáng)度應(yīng)達(dá)2MPa之上，但針對混凝土冷再生而言，混凝土使用量一般不可超出6%。假如再生層中粉料過少，RAP配合比不科學(xué)(其配合比操縱曲線圖可參考混凝土平穩(wěn)砂礫石配合比曲線圖)，但經(jīng)實(shí)驗后摻入一部分規(guī)格型號料來調(diào)節(jié)配合比，在確?；炷烈磺姓Ｊ褂昧康那疤釛l件下確保再生層品質(zhì)。
In situ cold recycling construction can carry out the design scheme according to the specific conditions of old formwork lifting raw materials of different roads, and select different preservatives, which can ensure the character and construction quality of recycled raw materials, produce thick and symmetrical bonding layer, and then ensure the application period of roads after maintenance. For example, the seven day unconfined tensile strength of the recycled layer of all recycled roads of Qingxian No. 1 machinery plant, Cangzhou East Outer Ring Road and Jilin line 202 project (the amount of concrete added is 6%) shall be above 3Mpa. The asphalt mixture of the general cold recycled layer shall be the asphalt road material rap from the original pavement structure. The key to the evaluation of the cold recycled layer shall be controlled according to its compressive strength. The compressive strength shall be determined by the technology department according to the grade of the pavement. The seven-day unconfined tensile strength shall be above 2MPa. However, for the cold recycling of concrete, the use of concrete shall not exceed 6%. If there is too little powder in the recycled layer, the rap mix proportion is unscientific (the mix proportion control curve can refer to the concrete stable sand gravel mix proportion curve), but after the experiment, some specifications and models are added to adjust the mix proportion, so as to ensure the quality of the recycled layer on the premise of ensuring all the normal use of concrete.
6.具備環(huán)境保護(hù)優(yōu)點(diǎn)
6. It has the advantages of environmental protection
應(yīng)用傳統(tǒng)式的道路檢修方式，瀝清路面廢料量十分大，對自然環(huán)境導(dǎo)致環(huán)境污染，很多新型材料的采掘，也會導(dǎo)致資源降低和自然環(huán)境的毀壞，選用傳統(tǒng)式基坑開挖施工加工工藝時，施工單位及小區(qū)業(yè)主均對很多的“廢棄物”解決頭疼不己，儲放占有很多場所，并導(dǎo)致二次污染。選用冷再生施工，不需解決此外解決廢料料，可避免所述難題。它不但能夠 節(jié)省很多項目投資，更有益于生態(tài)環(huán)境保護(hù)，因而被大家稱作“翠綠色”施工技術(shù)性。
Using the traditional road maintenance method, the amount of asphalt pavement waste is very large, resulting in environmental pollution to the natural environment. The excavation of many new materials will also lead to the reduction of resources and the destruction of the natural environment. When using the traditional foundation pit excavation construction and processing technology, the construction unit and community owners have a headache for many "wastes" and occupy many places for storage, And cause secondary pollution. Cold recycling construction is selected, which does not need to be solved. In addition, the problem can be avoided by solving waste materials. It can not only save a lot of project investment, but also benefit the ecological environment protection. Therefore, it is called "green" construction technology.
