在道路施工的舞臺上，冷再生機(jī)堪稱 “地面舞者”，通過對舊路面的破碎、拌和與再生，讓道路重獲新生。然而，這臺 “舞者” 能否在復(fù)雜多變的施工場地中自如穿梭，離地間隙與通過性起著關(guān)鍵作用。對于租賃冷再生機(jī)的施工團(tuán)隊來說，深入了解這些性能要素，才能讓設(shè)備在施工中發(fā)揮最大效能。

　　On the stage of road construction, the cold recycling machine can be called a "ground dancer", which breaks, mixes, and regenerates the old road surface to give it a new life. However, whether this "dancer" can freely shuttle in the complex and ever-changing construction site, the ground clearance and passability play a key role. For construction teams leasing cold recycling machines, a deep understanding of these performance elements is necessary to enable the equipment to achieve maximum efficiency during construction.

　　冷再生機(jī)的離地間隙，就像是它的 “安全底線”，直接決定了其在不同地形上行駛的安全性。這個參數(shù)指的是設(shè)備底部最突出部位到地面的垂直距離。在實際施工中，道路施工現(xiàn)場的地形千差萬別，有的路面坑洼不平，布滿大大小小的凹陷；有的地方堆積著施工廢料或散落的石塊；還有的施工現(xiàn)場會有臨時搭建的低矮障礙物。如果冷再生機(jī)的離地間隙過小，在行駛過程中，設(shè)備底部的部件，如傳動裝置、拌和裝置等，就很容易與地面凸起物發(fā)生碰撞，不僅可能損壞設(shè)備部件，影響施工進(jìn)度，還可能引發(fā)安全事故。例如，在一些老舊城區(qū)的道路改造工程中，地下管線施工留下的溝槽、凸起的井蓋等，都對冷再生機(jī)的離地間隙提出了挑戰(zhàn)。一般來說，具備較高離地間隙的冷再生機(jī)，能夠更輕松地跨越這些障礙，在復(fù)雜地形上保持穩(wěn)定行駛，減少設(shè)備受損風(fēng)險。

　　The ground clearance of the cold recycling machine is like its "safety bottom line", directly determining its safety when driving on different terrains. This parameter refers to the vertical distance from the most prominent part of the bottom of the device to the ground. In actual construction, the terrain of road construction sites varies greatly, with some roads having potholes and uneven surfaces covered in large and small depressions; Some places are piled up with construction waste or scattered stones; Some construction sites may have temporarily erected low obstacles. If the ground clearance of the cold recycling machine is too small, during the driving process, the components at the bottom of the equipment, such as the transmission device, mixing device, etc., are easily collided with the ground protrusions, which may not only damage the equipment components, affect the construction progress, but also cause safety accidents. For example, in some old urban road renovation projects, the grooves and protruding manhole covers left by underground pipeline construction pose challenges to the ground clearance of the cold recycling machine. Generally speaking, cold recycling machines with higher ground clearance can more easily overcome these obstacles, maintain stable driving on complex terrains, and reduce the risk of equipment damage.

　　通過性則是衡量冷再生機(jī)能否順利通過各種施工環(huán)境的綜合指標(biāo)，它與離地間隙緊密相關(guān)，但又不僅僅取決于此。冷再生機(jī)的整機(jī)尺寸，包括長度、寬度和高度，對通過性影響顯著。狹窄的施工路段，如城市里的小巷、鄉(xiāng)村小道，寬度有限，如果冷再生機(jī)機(jī)身過寬，可能根本無法駛?cè)?；而一些橋梁、涵洞等特殊路段，對設(shè)備的高度有嚴(yán)格限制，過高的冷再生機(jī)將被拒之門外。此外，設(shè)備的軸距、輪距以及輪胎的規(guī)格和性能，也會影響其通過性。較短的軸距使冷再生機(jī)轉(zhuǎn)彎半徑更小，在狹窄空間內(nèi)轉(zhuǎn)彎、掉頭更加靈活；合適的輪距有助于設(shè)備在松軟或不平的地面上保持平衡；具備良好抓地力和胎紋設(shè)計的輪胎，能增強(qiáng)設(shè)備在泥濘、濕滑路面上的通過能力。比如在山區(qū)道路施工時，泥濘的山路和陡峭的坡道，就需要冷再生機(jī)擁有出色的輪胎性能和合理的軸距設(shè)計，才能安全、高效地完成施工任務(wù)。

　　The passability is a comprehensive indicator that measures whether the cold recycling machine can smoothly pass through various construction environments. It is closely related to the ground clearance, but not only depends on it. The overall dimensions of the cold recycling machine, including length, width, and height, have a significant impact on its passability. Narrow construction sections, such as small alleys and country roads in cities, have limited width. If the cold recycling machine body is too wide, it may not be possible to enter at all; However, some special road sections such as bridges and culverts have strict height restrictions on equipment, and excessively high cold and fresh air will be rejected. In addition, the wheelbase, wheelbase, and tire specifications and performance of the equipment can also affect its passability. The shorter wheelbase makes the turning radius of the cold recycling machine smaller, making it more flexible to turn and make U-turns in narrow spaces; Appropriate wheelbase helps equipment maintain balance on soft or uneven ground; Tires with good grip and tread design can enhance the equipment's ability to pass through muddy and slippery roads. For example, during road construction in mountainous areas, muddy mountain roads and steep slopes require cold recycling machines to have excellent tire performance and reasonable wheelbase design in order to safely and efficiently complete construction tasks.

　　在租賃冷再生機(jī)時，施工團(tuán)隊必須根據(jù)具體的施工項目需求，仔細(xì)考量設(shè)備的離地間隙與通過性。在施工前，對施工現(xiàn)場進(jìn)行詳細(xì)勘察，了解地形地貌、道路狀況、障礙物分布等信息，據(jù)此選擇適配的冷再生機(jī)。如果施工場地地形復(fù)雜，障礙物多，就應(yīng)優(yōu)先選擇離地間隙大、整機(jī)尺寸緊湊、通過性強(qiáng)的設(shè)備；若施工區(qū)域相對平坦開闊，則可在滿足基本施工要求的前提下，綜合考慮其他性能參數(shù)。同時，租賃后也要對設(shè)備進(jìn)行必要的檢查和調(diào)試，確保輪胎氣壓正常、部件連接穩(wěn)固，以保障冷再生機(jī)在施工過程中始終保持良好的通過性能，讓這臺 “地面舞者” 在道路施工的舞臺上盡情施展技藝，高效完成施工任務(wù)。

　　When leasing a cold recycling machine, the construction team must carefully consider the ground clearance and passability of the equipment based on specific construction project requirements. Before construction, conduct a detailed survey of the construction site to understand the terrain, road conditions, obstacle distribution, and other information, and based on this, select the appropriate cold recycling machine. If the terrain of the construction site is complex and there are many obstacles, priority should be given to selecting equipment with large ground clearance, compact overall size, and strong passability; If the construction area is relatively flat and open, other performance parameters can be comprehensively considered while meeting the basic construction requirements. At the same time, necessary inspections and debugging of the equipment should be carried out after leasing to ensure normal tire pressure and stable component connections, in order to ensure that the cold recycling machine maintains good passing performance during the construction process, allowing this "ground dancer" to fully display their skills on the stage of road construction and efficiently complete construction tasks.
