反铲掘客机陈设在路堑的左近,依据外形选择沟端掘客或沟侧掘客步伐抑制施工。用自卸车与掘客机共同,将掘客的泥土移运至卸土场。
Backhoe excavators are located near the left of the cutting. Digging methods at the end of the trench or at the side of the trench are selected to stop construction according to the situation. The excavated soil is transported to the dump with the help of dump truck and excavator.
填筑路堤
Embankment filling
反铲掘客机与自卸车共同可抑制填筑路堤作业,掘客机在取土场依照上述掘客步伐取土即可。掘客路堑和填筑路堤施工中,自卸车共同反铲掘客机作业时所需求的车辆数,除与掘客机、自卸车的结果有关外,还与运输隔绝、路途环境、驾驶员应用技术等要素有关,庞大可用预算法求出,然后颠末过细作业予以落实。在此进程中,以餍足掘客机不中缀作业、又不让自卸车停滞爲准绳。
The backhoe excavator and dump truck cooperate to stop filling embankment, and the excavator can extract soil according to the above excavation method in the excavation yard. In excavation of cutting and embankment construction, the number of vehicles required by dump truck cooperating with backhoe excavator is related not only to the function of excavator and dump truck, but also to transportation interval, road condition and driver's operation technology, which can be calculated by budget method, and then implemented by detailed operation. In this process, it is necessary to satisfy the excavator's unfixed work and not to let the dump truck stop.
平面掘客
Stereoscopic excavation
反铲掘客机抑制平面掘客作业时可采取垂直掘客法可对等掘客法。
Backhoe excavator can use vertical excavation method to stop excavation.
垂直掘客法:掘客机垂直于义务面上抑制掘客。垂直掘客法的益处是,掘客机的两侧均可停放自卸车,一侧自卸车运输时另一侧自卸车抑制装载,并且掘客机反转展转达角度不超越90°,有利于提高着业遵从。
Vertical excavation method: excavator is perpendicular to the task surface to stop excavation. The advantage of vertical excavation method is that dump trucks can be parked on both sides of excavator, dump trucks on one side stop loading on the other side when dump trucks are transported, and the turning angle of excavator does not exceed 90 degrees, which is conducive to improving operation efficiency.
平行掘客法:反铲掘客机提高方向与义务面扩展方向平行,可抑制直线掘客和装载,它适用于细长的掘客作业。由于自卸车只能在一侧抑制装载,因此斲丧遵从较低。
Parallel excavation method: The heading direction of backhoe excavator is parallel to the expansion direction of task surface, and it can stop straight excavation and loading. It is suitable for slender excavation operation. Because the dump truck can only stop loading on one side, the consumption efficiency is low.

修筑物基本的掘客

运用反铲掘客修筑物基本,其益处是:掘客机和自卸车均在空中上,不需求倾斜通道;基本的垂直面可准确掘客,对水平基本或有坡度的基本都能很好地抑制掘客,沟底也能按要求掘客,不需求人工修正。
The advantages of using backhoe to excavate the roots of buildings are: excavators and dump trucks are in the air, and there is no need for inclined passages; the vertical plane of the roots can be excavated accurately, the excavation of the roots with or without slope can be stopped well, and the bottom of ditches can be excavated according to the requirements without manual correction.
掘客沟槽
Excavate the grooves
反铲掘客机抑制沟槽掘客作业是契合的。掘客沟槽时留神沟槽底部的水平度和掘客机应有的提高移动,多么技艺抵达施工要求而不需求人工修整。反铲掘客机掘客沟槽有浅沟的垂直掘客法和深沟的垂直掘客法等三种施工步伐。
Backhoe excavator is the most suitable way to stop trench excavation. When excavating trenches, pay attention to the degree of the bottom of the trench and the forward movement of the excavator, so as to meet the construction requirements without manual repair. There are three construction methods for excavating trenches by backhoe excavator, namely, vertical excavation of shallow trenches and vertical excavation of deep trenches.
1)浅沟的垂直掘客法。掘客机的动臂确实呈水平外形,在掘客机提高的进程中同时也完成掘客义务。采取这种掘客法作业循环韶光很短,但铲斗每次装满遵从低。掘客壮实泥土时须与作业面成垂直外形,以包管有较大的掘客力。
1) vertical excavation of shallow gully. The arm of excavator is in the form of degree, and it also completes the excavation task in the process of excavator's progress. This excavation method is very short in operation cycle, but the bucket is always filled with low efficiency. When excavating strong soil, it must be perpendicular to the working surface to ensure greater excavation power.
2)浅沟的平行掘客法。这种掘客步伐是反铲掘客的行进方向和沟槽的中心线平行,动臂与机体(行走机构)成直角,并共同以掘客机的移动,掘客步伐与上述垂直掘客法相反。
2) parallel excavation method for shallow gully. This excavation method is that the direction of backhoe excavation is parallel to the center line of the trench, the arm is at right angle to the body (walking mechanism) and cooperates with the movement of excavator. The excavation method is contrary to the vertical excavation method mentioned above.
3)深沟的垂直掘客法。深沟的垂直掘客可采取两种作业要领:一种与浅沟的对等掘客法相反;另一种是分层分段掘客,先挖浅沟,当掘客机沿沟槽方向行进、挖到长度约爲掘客机长度的1/2时,再挖到所端正的深度。掘客时使动臂下降,斗杆确实与作业面垂直,并共同以掘客机的提高移动。这种分层分段掘客步伐用斗杆掘客较方便,容易装满铲斗,驾驶员在驾驶室内也容易掌握掌握斗杆的要领。由于重要依托斗杆掘客,因此掘客作业循环韶光较长。又由于掘客机需频繁地行进和提高,故壮实地带不宜采取这种掘客要领
3) vertical excavation of deep trenches. Vertical excavation of deep trenches can be carried out in two ways: one is opposite to the equivalent excavation of shallow trenches; the other is to excavate shallow trenches in layers and sections. When the excavator travels along the trench direction and reaches a length of about 1/2 of the excavator's length, the excavation will reach the regular depth. When excavating, the arm is lowered, and the bucket bar is perpendicular to the working face, and is used to move the excavator forward. This layered and sectional excavation method is more convenient to excavate with bucket pole, easy to fill bucket, and easy to grasp the action of bucket pole in the driver's cab. Due to the excavation of secondary support rods, the operation cycle is longer. Because excavators need to travel and advance frequently, it is not appropriate to use this excavation method in the solid area.
