Do you know what the excavation is different from the excavation?
The most important difference between excavation and trenching is the digging depth. In such a way that to dig the ground for the purpose of digging, a maximum of half a meter of the ground should be dug. But in excavation, this size should be more than half a meter and sometimes it reaches tens of meters. The most important reason for excavating and excavating the ground in the construction of civil and construction structures is to level the ground in order to increase the resistance of the structure against tensile forces such as earthquakes.
What is excavation?
The areas that are considered for construction do not always have smooth and flat land and there is always the possibility of high and low places in it. Since the foundation of the building must be placed on a smooth and even ground, before any action on the ground, it must be completely leveled and prepared.
What is the excavation?
Excavation operations include any excavation of the ground at a level lower than the foundation of the adjacent building or at a level lower than the ground level, which is done for the purpose of constructing a building. Half a meter of the ground is done. With a little care and attention to the definition provided, you can find out the difference between excavation and excavation, both of which are associated with digging the ground for building and other civil structures.
Stages of excavation and excavation
Excavation and excavation are both among the first necessary actions that must be done in all construction projects. Perhaps one of the main reasons for ignoring the difference between excavation and excavation and treating these two cases as one is the same reason. In general, the most important measures that must be taken for excavation and excavation are as follows:
Preparing a map
Conducting soil mechanics tests
Checking the level of underground water
Considering Neighboring structures
Obtaining necessary permits from water, electricity, gas, sewage, telecommunication, fire department and police station inspection of city utility pipes
Soil type examination
Excavation of the ground to the specified depth and also up to Access time to hard soil
Compensation for additional excavation if more than the amount specified in the map has been excavated
Covering the excavated surface with sand and cement in order to prevent damage from changing factors and natural disasters br> Using bracing in case of instability of pit walls.
The main cause of excavation and excavation
The difference between excavation and excavation, as well as the difference between piling and excavation, has nothing to do with the main reason for carrying out these processes in the construction of construction structures. In the previous articles, we mentioned that the reason for digging the ground is to level the ground to build a structure on it.
Investigating the types of land in excavation and excavation operations
Manual soil
is soil that has a soft and light texture and can be excavated and dug with manual tools, and its digging does not require mechanical machines.
Stone land
Lands that are made up of stones and are very hard are in this category. In this type of land, it is not possible to dig with hand tools and it is necessary to use drilling machines. Also, the most important difference between excavation and excavation must be observed and despite the hardness of the land, the size specified in the map must be dug. On it, it is placed in the category of Daj lands. Since these lands also have hard and compact soil; Drilling machines are used to dig them.
Kalangi land
Kalangi land has almost harder soil than manual and muddy land. But during digging, there is no pickaxe left on it for the purpose of excavating and excavating. It absorbs mud. Digging this type of land by hand is easily possible due to the looseness of the soil. But to use drilling machines, it should be done in the seasons when there is little chance of rain.
