长臂挖掘机轻松防汛抢险

日期:2019-12-04   来源:http://www.dybocheng.com
  更近几年,随着大河大江的防汛抢险工作的不断实践与创新,以前以大量人工抛石为主的传统抢险模式已淡出历史舞台,多工种、高性能的机械化协调抢险作业应运而生,其中表现更为抢眼的无疑是长臂挖掘机
  In recent years, with the continuous practice and innovation of flood control and rescue work in big rivers and rivers, the traditional rescue mode, which used to be dominated by a large number of artificial riprap, has faded out of the historical stage, and the mechanized coordinated rescue work with multiple types of work and high performance has emerged, among which the most eye-catching one is the long arm excavator.

  在过去,以大量人工抛石为主的传统抢险模式存在“三高”和“三低”的缺陷,即劳动强度高、抢护风险高、抢护成本高、机动性低、持续时间低、抢险效率低。同时人力资源的投入数量与险情的抢护时间不成正比,严重制约了抢险的效率。而长臂挖掘机具有机动性强、性高、抢护成本低、持续时间长等优点,根据各个部位险情发展的轻重缓急及时补给抢险物资,节省了抢险时间,有效遏制了险情的扩大蔓延。因此,利用长臂挖掘机抢险具有良好的前景。
  In the past, the traditional rescue mode, which is dominated by a large number of artificial riprap, has the defects of "three high" and "three low", that is, high labor intensity, high risk, high cost, low mobility, low duration and low efficiency. At the same time, the input of human resources is not directly proportional to the time of emergency rescue, which seriously restricts the efficiency of emergency rescue. The long arm excavator has the advantages of strong mobility, high safety, low cost of rescue and maintenance, and long duration. According to the priority of the development of each part of the dangerous situation, it supplies the rescue materials in time, saves the rescue time, and effectively curbs the expansion and spread of the dangerous situation. Therefore, the long arm excavator has a good prospect.
  长臂挖掘机在抢险中的优势
  Advantages of long arm excavator in emergency rescue
  1、抢险机动性强、调集迅速。
  1. Strong rescue mobility and rapid mobilization.
  抢险成败的关键在于能否时间到达出险现场进行抢护,而长臂挖掘机可以通过拖车前往目的地,不足半小时就能到达出险地点进行抢护,做到抢护及时。
  The key to the success or failure of the rescue lies in whether it can arrive at the scene of the accident for rescue at the first time, while the long arm excavator can go to the destination through the trailer, and can arrive at the place of the accident for rescue in less than half an hour, so as to achieve timely rescue.
  2、突出抢险,提高抢险效率。
  2. Highlight the key points of rescue and improve the efficiency of rescue.
  以往人工险情抢护抛石往往无法及时到位,大部分石料停滞在坝坡上,而常规挖掘机却只能将石料抛到半坡。长臂挖掘机却能在抢险过程中根据险情的轻重缓急,在坝面上来去自如,快速移动,突出一个“快”字。
  In the past, the artificial rock riprap can't be put in place in time in case of dangerous situations. Most of the stone materials stagnate on the dam slope, while the conventional excavator can only throw the stone to the half slope. However, the long arm excavator can move freely and quickly on the dam surface according to the priority of the dangerous situation in the rescue process, highlighting the word "fast".
  3、降低劳动强大,压缩抢险成本。
  3. Reduce labor force and rescue cost.
  常规挖掘机抢险的时候,往往需要配合使用人海战术,劳动强度大,同时抢险过后需要重新整修坝坡,增加了抢险成本。而利用长臂挖掘机抢险,节省了人工二次抛石、整修坝坡等费用。
  When conventional excavators rescue, they often need to cooperate with the use of human sea tactics, with high labor intensity. At the same time, after the rescue, they need to rebuild the dam slope, which increases the rescue cost. By using the long arm excavator, the cost of artificial second riprap and dam slope repair can be saved.
  4、持续作业时间长,适合抢护重大险情。
  4. The continuous operation time is long, which is suitable for the rescue and protection of major dangerous situations.
  抢险的关键在于时间,抢护要及时,控制住险情进一步扩大;其次抢险要一气呵成,避免抢险料物大量流失。以往的常规挖掘机使用往往需要配合大量人工抛石,持续有效运转时间不超过4小时,时间一长就会力不从心,无法保障抢险工作的连续性。而使用长臂挖掘机,除去加油料的时间,基本可以连续作业,确保抢险一气呵成。
  The key to rescue lies in time. First of all, it is necessary to rescue in time and control the further expansion of the danger. Second, it is necessary to complete the rescue in one go to avoid the loss of a large number of rescue materials. Conventional excavators used in the past often need to cooperate with a large number of artificial riprap, the continuous and effective operation time is not more than 4 hours, and it will be unable to meet the demand after a long time, and can not guarantee the continuity of rescue work. The use of long arm excavators, to remove the time of refueling, can basically continue to work, to ensure a complete rescue.
  由此可见,长臂挖掘机在防汛抢险的过程中具有机动性强、抢护效率高、抢护成本低等优点,非常适合工坝岸等重大险情,具有良好的发展前景。
  It can be seen that the long arm excavator has the advantages of strong mobility, high efficiency and low cost in the process of flood control and emergency rescue, which is very suitable for the construction dam bank and other major dangerous situations and has a good development prospect.
