Trench digging can be said to be one of the basic operations of a mini excavator. It seems simple but actually has a high technical content. In the process of digging trenches, many novices often have problems such as not being straight, digging off-track, and the bottom of the trench is wide or narrow. So what are the operating skills of trench digging? Take a look at the basic operation of trenching shared by “Rippa Group”.

The trench must be dug straight

The most basic principle of trenching is to follow the principle of straight digging. Generally, the route of the lime trench is drawn on the construction site. The center line of the chassis of the mini excavator is aligned with the lime line, and the teeth in the middle of the bucket correspond to the lime line, so that it is not easy to dig away. Biased.

If there is no lime line, you can use the track to press out a connecting line first, and the track traces left can play the role of the lime line. Bucket motion can then be adjusted to the track print left by backing up.

Ditch the surface first

When formally excavating, first take the surface layer, and then remove the lower layer. Never dig to the bottom at one time, especially the excavation of deep trenches is especially important; when digging a trench larger than the width of the bucket, first dig both sides, and then Dig in the middle.

Maintain the flatness of the slope

Many novices are not good at digging ditches, mainly because they have not done the principle of neatness, and the detailed operation needs to be further improved. From the beginning of opening the V-shaped ditch to the end, the slope must maintain the same slope. Of course, the soil quality and the depth of the ditch are different, and the slope needs to be adjusted accordingly.

The two lines on the graph are straight, which is the premise of keeping the slope of the ditch flat. When digging a ditch, the operator must pay attention to the loose soil on the side of the ditch to prevent the soil from falling, and clean it up with a bucket in time.

Ditch Bottom Control.

The control of the bottom of the ditch is very important. At this time, it is necessary to use the skills of throwing squares and leveling. If the trench is to install water pipes for drainage, a certain slope at the bottom is required; if it is a house foundation pit, the bottom is required to be level.

In fact, many operators are not sure about the height of the bottom of the ditch. When there are surveyors, they can ask the construction workers to measure with instruments and measure while digging. If you don’t have any, you can find some references, and you should get out of the car to observe more.

Three ways to dig a trench.

The basic operation skills of trenching have been briefly introduced above, and finally three trenching methods are introduced for you:

(1) Ride-digging type: mainly in open areas, the excavator is parked in the middle of the ditch to be excavated, and the bucket is dug between the two crawlers.

(2) Side-by-side type: It refers to the relatively narrow area of the site, like a clear water channel, the bucket only digs along one side of the track line (here requires the use of slope skills).

(3) Face-to-face type: mainly for the excavation of road culverts, which means that the excavator is parked at a 90-degree angle to the side of the ditch (it should be noted that when the ditch is relatively deep, the bucket cylinder may touch the ditch side)

In short, the operator needs to pay special attention to the straightness of digging, the flatness of the slope, the control of the bottom of the ditch, etc. in the process of digging the ditch. It is not difficult to choose the appropriate ditching method.

Una delle attrezzature più preziose in un cantiere è l'escavatore, che ha aiutato innumerevoli progetti a lavorare in modo più efficiente ed efficace. Ma a cosa serve un escavatore e perché è così essenziale per molti lavori con attrezzature pesanti?

Per capire a cosa serve un escavatore, è utile esaminarne i componenti. Un escavatore contiene la cosiddetta struttura, il sottocarro, il braccio, il bastone e la benna. Questi componenti sono dotati di motori e ingranaggi per muovere l'attrezzatura, sollevare la benna e un posto per sedersi e controllare il macchinario.

Gli escavatori sono utilizzati principalmente per scavare trincee, buche e fondamenta, fornendo la potenza necessaria per svolgere questi compiti in modo molto più semplice ed efficace rispetto a qualsiasi altra attrezzatura pesante presente sul mercato. Le aziende di molti settori possono guardare agli escavatori in vendita in Cina grazie all'ampia gamma di settori in cui vengono utilizzati, tra cui la silvicoltura, l'industria mineraria e tutti i tipi di costruzione. Oltre a scavare, gli escavatori sono comunemente utilizzati per progetti come la demolizione, il dragaggio di fiumi, la movimentazione di materiali o semplicemente il sollevamento di oggetti pesanti.

Con una così ampia gamma di utilizzi, è logico che esistano diversi tipi di escavatori per trovare quello giusto per il lavoro da svolgere. Un esempio è l'escavatore cingolato e gommato, che è perfetto quando il lavoro richiede attività come lo scavo, la movimentazione dei materiali, il taglio delle sterpaglie, la demolizione, l'estrazione a cielo aperto, i lavori forestali e molto altro ancora.

Esistono anche mini escavatori, più piccoli e leggeri, che facilitano il trasporto rapido ed efficiente nei vari cantieri. Questi tipi di escavatori compatti sono ideali per lo scavo di trincee e per un'ampia gamma di lavori di pubblica utilità. In alcuni casi, grazie ai progressi compiuti nei sistemi idraulici, questi escavatori più piccoli possono addirittura superare le macchine più grandi, facendo valere il loro peso come molte persone che cercano attrezzature pesanti in vendita.

Come guidare l'escavatore in sicurezza?

No matter what job you do, your health and life safety are the most important. “Excavators” in the engineering field should also have this awareness to protect themselves and their excavators at work. Speaking of safety knowledge related to driving an excavator, there are many. Here I will share with you the precautions before work.

First, pay attention to the state of the operator. As the core of the work, the excavator operator will make the excavator, a huge machine, perform various actions in the following work, and their status is closely related to the safety of the work. Therefore, if the operator is found to be fatigued, sick, mentally disturbed, or under the influence of drugs and alcohol, it is necessary to consider replacing the operator or suspending the operation, otherwise the operator is likely to make the excavator make improper actions due to physical reasons and endanger himself. and the safety of those around them. In addition, operators should pay attention to clothing, preferably wearing a helmet and safety shoes.

Secondly, the overall inspection of the excavator should be carried out. Check whether there are abnormal conditions such as oil leakage and cracks in the working parts of the oil cylinder, traveling device, slewing device and engine. If abnormal conditions are found and the operation is still carried out, the excavator will be seriously damaged on the one hand, and on the other hand, it may occur during the work. Terrible phenomena such as machine failure and machine out of control endanger life safety. So if you find that the machine is abnormal, please contact the service personnel of the local agent to solve the problem in time. Check whether the work lights and wipers can work normally, clean the windows and rearview mirrors to ensure a good view during work, tidy up the interior of the cab to obtain a spacious and comfortable operating environment, and prepare water bottles to ensure that the body can be replenished in time during work moisture. When demolishing abandoned buildings, grabbing wood and steel, etc., check whether the protective fences in front of and above the cab are firm.

Finally, confirm the working environment of the excavator. There are often workers who rest or hide from the sun under the counterweight of the excavator. Make sure that they evacuate before the engine starts, and prohibit other personnel from standing within the excavator’s digging radius. If the crushing work is about to be carried out, it may cause broken If stones are scattered, consideration should be given to expanding the scope of “personnel prohibited from entering”. If you are about to work in a swamp or a quagmire, consider whether the environment can withstand the grounding pressure of the excavator. If necessary, place a large iron plate in advance to prevent the excavator from falling into the swamp or quagmire. If excavation work is carried out on urban streets, ask professionals in advance whether the excavation work will damage sewer pipes and underground cables. Reckless excavation may easily cause sewage to be sprayed or the excavator to be connected to high-voltage electricity.
