Excavations

139

Land Movement is understood as the set of actions to be carried out in a land for the execution of a work. This set of actions can be performed manually or mechanically.

Prior to the start of any action, the Stakeout Works must be carried out, provide access for
machinery, trucks, ramps, etc. is usual that before beginning the movement of earth, an action is made at the level of the surface of the land, cleaning of bushes, plants, trees, brush, weeds and garbage that could be found in the ground; This operation is called clearing and clearing.

When the terrain is already clean and free, the stakeout is carried out and the excavation
begins. Excavation is the movement of earth made in the open and by manual means, using pick and shovels, or mechanically with excavators, and whose purpose is to reach the starting plane of the building, i.e. the foundations.

Ground works

Ground works are usually carried out by mechanical means with the appropriate machinery in each case. During the Stakeout Work we must foresee the location of ramps for the exit and entry of trucks; it is necessary to delimit the area of ​​our action and mark external reference points that will help us to take topographic data.

You must take into account the final elevation of the excavation and leave the land level, since it would be very costly to have to re-fill the executed. It is important to know the angle of natural slope of the terrain, especially those of little cohesion, to know the exact location when digging, leaving wall faces.

The appropriate slope for each terrain applies not only to the main cut but to all excavation
fronts, including the ramps. In the case where, due to the occupation of the building within the terrain, the necessary slopes could not be made, excavation by batches should be resorted to.

Works in Rock

It will include, for the purposes of measurement and fertilization, the one corresponding to all rock masses, of materials that have massive rock characteristics that are cemented so solidly that they have to be excavated using explosives. Excavation in transit ground: This will include the material formed by decomposed rocks, very compact earth, for excavation, the use of explosives, seismic waves in the ground, and other procedures during the execution of the work.

They will be used for rock excavation, heavy duty hydraulic hammers: it is used for construction material. That a wide range of models and sizes is available, from 100 kg to more than 10 tons. Expansive cements: It is so called because its basic composition is calcined limestone, its appearance, its form of use and mixture are similar to those of a cement but its action is contrary since the mixture when hydrated increases its volume generating a strong expansion.
In addition, comprehensive services of excavation + recycling are offered, given that the
materials from these excavations (rock) are suitable for the production of artificial aggregates.
The recycling of the rock is done in the work itself, if it has the right proportions, or in nearby facilities. In this way a considerable saving in transport costs is achieved, discharge canon, while at the same time achieving an artificial aggregate of great added value and excellent characteristics. All this contributes to collaborate with the environment and sustainable development, while not increasing the material execution times of the works and decreasing the operating costs.

Access
When working in an excavation, it is necessary to ensure that there are safe means of entry and exit, such as a ladder properly secured. Lighting. The aria surrounding the excavation must be well lit, especially at the access points and at the openings in the barriers. Vehicles. Suitable stop blocks must be placed on the surface and anchored to prevent vehicles, dump trucks from slipping into the excavations, risk that occurs especially when they reverse to discharge. The blocks must be at sufficient distances from the shore to avoid the dangers of loosening the weight of the vehicles.
