Puede decirse que la excavación de zanjas es una de las operaciones básicas de una miniexcavadora. Parece simple pero en realidad tiene un alto contenido técnico. En el proceso de excavación de zanjas, muchos novatos a menudo tienen problemas tales como no ser recto, excavar fuera de la pista, y el fondo de la zanja es ancho o estrecho. Entonces, ¿cuáles son las habilidades operativas de la excavación de zanjas? Eche un vistazo al funcionamiento básico de la excavación de zanjas compartido por el "Grupo Rippa".

La zanja debe cavarse recta

El principio más básico de la excavación de zanjas es seguir el principio de la excavación recta. Generalmente, el trazado de la zanja de cal se dibuja en la obra. La línea central del chasis de la miniexcavadora se alinea con la línea de cal, y los dientes del centro de la cuchara se corresponden con la línea de cal, para que no sea fácil excavar en sentido contrario. Sesgada.

Si no hay línea de cal, puede utilizar la oruga para presionar primero una línea de conexión, y las huellas de la oruga a la izquierda pueden desempeñar el papel de la línea de cal. A continuación, el movimiento de la cuchara puede ajustarse a la huella dejada retrocediendo.

Deshacerse primero de la superficie

Al excavar formalmente, primero tome la capa superficial, y luego retire la capa inferior. Nunca cavar hasta el fondo de una sola vez, sobre todo la excavación de zanjas profundas es especialmente importante; al excavar una zanja más grande que el ancho de la cubeta, primero cavar ambos lados, y luego Dig en el medio.

Mantener la planitud de la pendiente

Muchos novatos no son buenos cavando zanjas, principalmente porque no han hecho el principio de la pulcritud, y hay que seguir mejorando la operación detallada. Desde el principio de la apertura de la zanja en forma de V hasta el final, la pendiente debe mantener la misma inclinación. Por supuesto, la calidad del suelo y la profundidad de la zanja son diferentes, y la pendiente debe ajustarse en consecuencia.

Las dos líneas del gráfico son rectas, lo que constituye la premisa de mantener plana la pendiente de la zanja. Al excavar una zanja, el operario debe prestar atención a la tierra suelta en el lateral de la zanja para evitar que la tierra se caiga, y limpiarla con un cazo a tiempo.

Control de fondo de zanja.

El control del fondo de la zanja es muy importante. En este momento, es necesario utilizar las habilidades de tirar escuadras y nivelar. Si la zanja es para instalar tuberías de agua para el drenaje, se requiere cierta pendiente en el fondo; si es una zanja para los cimientos de una casa, se requiere que el fondo esté nivelado.

De hecho, muchos operarios no están seguros de la altura del fondo de la zanja. Cuando hay topógrafos, pueden pedir a los trabajadores de la construcción que midan con instrumentos y midan mientras cavan. Si no disponen de ellos, pueden buscar algunas referencias, y deben bajarse del coche para observar más.

Tres formas de cavar una zanja.

Anteriormente se han presentado brevemente las técnicas básicas de zanjeo y, por último, se presentan tres métodos de zanjeo:

(1) Tipo de excavación sobre orugas: principalmente en zonas abiertas, la excavadora se estaciona en medio de la zanja a excavar, y la cuchara se excava entre las dos orugas.

(2) Tipo lado a lado: Se refiere a la zona relativamente estrecha del sitio, como un canal de agua clara, el cubo sólo excava a lo largo de un lado de la línea de la pista (aquí se requiere el uso de habilidades de pendiente).

(3) Tipo cara a cara: principalmente para la excavación de alcantarillas de carretera, lo que significa que la excavadora está estacionada en un ángulo de 90 grados con respecto al lado de la zanja (debe tenerse en cuenta que cuando la zanja es relativamente profunda, el cilindro de la cuchara puede tocar el lado de la zanja).

En resumen, el operario debe prestar especial atención a la rectitud de la excavación, la planitud de la pendiente, el control del fondo de la zanja, etc. en el proceso de excavación de la zanja. No es difícil elegir el método de excavación de zanjas adecuado.

One of the most valuables pieces of equipment on a construction site is an excavator, which has helped countless projects work more efficiently and effectively. But what is an excavator used for, and why is it so essential for many heavy equipment jobs?

To understand what an excavator is used for, it is helpful to look at the components. An excavator contains what is called a house, undercarriage, boom, stick, and bucket. These components feature the motors and gears to move the equipment, lift the bucket, and a spot for someone to sit and be in control of the machinery.

The main uses for an excavator are digging trenches, holes, and foundations, providing the power to do these tasks much more easily and effectively than any other piece of heavy equipment on the market. Companies across many industries may be looking at excavators for sale in China thanks to the wide range of industries they are used for, including forestry, mining, and all types of construction. In addition to digging, excavators are commonly used for projects such as demolition, dredging rivers, material handling, or just simply heavy lifting of objects.

With such a wide range of uses, it makes sense that there are different types of excavators to help find exactly the right one needed for the job at hand. One example is a tracked and wheel excavator, which is perfect when the job calls for things such as digging, material handling, brush cutting, demolition, open-pit mining, forestry work, and much more.

There are also mini excavators, which are smaller and lightweight, which makes them easier to transport quickly and efficiently to various construction sites. These types of compact excavators are ideal for trenching, as well as a wide range of utility work. In some cases, with the advances we have seen in hydraulic systems, these smaller excavators can even outperform larger machines, pulling their weight in a way that many people looking at heavy equipment for sale.

¿Cómo conducir su excavadora con seguridad?

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.
