In the process of establishing modern embankment heavy industry, the workload of long-distance soil transfer operation is increasing day by day. Therefore, many people think that the operation efficiency of open LHD is low and the LHD is useless. What role does the LHD play in the construction machinery of practical engineering?

目前在我們施工中應用比擬普遍的是公開鏟運機，這種鏟運機在施工中比擬靈敏便當，順應性強。鏟運機運土間隔適用于600米以內(nèi)，除淤泥和巖石以外的土質(zhì)都能施行施工作業(yè)，在往復循環(huán)的施工過程中自然碾壓即可到達普通工程請求的壓實系數(shù)，是其他施工機械無法停止的。

At present, the open scraper is widely used in our construction. This scraper is more sensitive, convenient and compliant in construction. The earth transportation interval of the scraper is suitable for the soil within 600m. The construction operation can be carried out for the soil other than silt and rock. During the reciprocating construction process, the natural rolling can reach the compaction coefficient required by the ordinary project, which can not be stopped by other construction machinery.

雖然目前施工范疇各種型號的發(fā)掘機和自卸汽車在施工中的有著普遍的運用，但在一些大中小型的水利工程，諸如河道的開挖，堤防的加固等工程中，特別是在土質(zhì)較軟的作業(yè)條件下，自卸車是無法完成運輸作業(yè)的，那么鏟運機就會成為無可替代的施工設備。

At present, various types of excavators and dump trucks are widely used in construction, but in some large, medium and small water conservancy projects, such as river excavation, embankment reinforcement and other projects, especially under the operating conditions of soft soil, the dump truck can not complete the transportation operation, so the scraper will become an irreplaceable construction equipment.

如今工程機械市場里，有不少人將鏟運機報廢處置，這自身是市場經(jīng)濟調(diào)理的結果，而不是說鏟運機無用武之地了，而只是適于鏟運機施工發(fā)揮優(yōu)勢的工程項目暫時較少而已。而在淮河主流沙潁河管理工程，南水北調(diào)工程開工后，鏟運機就會由冷變熱了，因而我們說鏟運機施工作業(yè)，在今后很長一個時期內(nèi)還將會優(yōu)勢長存，是不可或缺和替代的。

Nowadays, in the construction machinery market, many people scrap the LHD, which is the result of the adjustment of the market economy, not that the LHD is useless, but that there are only a few engineering projects suitable for LHD construction to give full play to its advantages. In the mainstream Shaying river management project of Huaihe River and the South-to-North Water Transfer Project, the LHD will change from cold to hot. Therefore, we say that the construction operation of LHD will continue to have advantages for a long time in the future, which is indispensable and alternative.

礦用鏟運機的施工方式將是長期存在不可短少的，鏟運機施工有著寬廣的前景和空間。只需注重和增強對鏟運機施工的科學管理和對鏟運機械的正確運用，即便在目前狀況下，鏟運機的施工效率依然是很可觀的。因而鏟運機施工仍然有著美妙的前景。

The construction mode of mine LHD will be indispensable for a long time. LHD construction has broad prospects and space. As long as we pay attention to and enhance the scientific management of scraper construction and the correct use of shovel machinery, even under the current situation, the construction efficiency of scraper is still considerable. Therefore, LHD construction still has a wonderful prospect.
