Soil testing is done to ensure that the soil is perfect for foundations for superstructure. The strong foundation ensures that superstructure or buildings build on them are firm and strong. The strength of the building depends on the strength of the foundation. The soil testing is done to know the existing conditions of soil and it’s characteristic to construct a suitable foundation to match the soil.
The type of soil testing needed can be determined by correlation of soil characteristics, which are taken from soil investigation reports, and tests from projects constructed. This soil testing results will determine the size, length, depth and capacity of the foundation being done for buildings.
If it is not possible to get the reliable data about piles or foundation, in the area, it can be taken by making a test pile and correlate with soil data. The tests which are conducted may include:
Types of soil tests –
Standard penetration test is done to know the point of friction between soil and pile or foundation. This also gives the friction or resistance given by each layer of soil to the pile
Static cone penetration is done to know the cohesion and subsequently, adhesion, of soft cohesive soils. It is also done to know the standard penetration test results for fine to medium sands. The static cone penetration test and standard penetration test is needed for both cohesive less and cohesive soil .Vane shear test reserved for clayey soils.
The ground water condition and permeability of soil is measured to know the type of foundation that can be constructed in the soil .The level of water in the bore is noted in the bore log. Because of low permeability of the soil, the water in the bore can rise to the water table level in several days.
The ground water tests Cement testing equipment manufacturer in Delhi are done to known the chemical effect on the concrete and pile. The cone penetration test for the same soil can come with substantial scatter. That is why; they are checked with information obtained from other tests or exploration methods.
By all these methods of soil testing, Soil test equipment suppliers in India if soil is not found suitable for the construction or it is of poor bearing capacity or filed with subsoil, then engineers have to take the decision to move the foundation laying somewhere else. They can also remove the poor soil and replace it with good compacted soil. The engineers can also improve the bearing capacity of the soil. But all these methods to improve the soil can delay the construction.
Construction activity of any kind starts with digging the earth and making the way for construction of foundation. The various equipments are used for earth work. Use of each of these equipments depends on the nature of work to be done.
Backhoe tractors are on the wheels or tracks and have backhoe at the end of the arm, which can be extended from the tube for work. The backhoe works on the hydraulic pressure. The digging is done from the short distance of the machine towards the machine. The depth of the digging depends on the length of the arm and depth to which its blades can go.
Loading shovel is similar to backhoe tractor but the only different is that the arm of the loading shovel extends upward and lifts the material for loading into bumper trucks. The loading shovels operate on tracked chain and can be taken to any surface during loading. The track chain gives it stability during lifting and loadings. The machine comes in various sizes and capacities.
Graders are used to spread the mud over the surface evenly and finely trim the subgades. They consists a blade which is wide and can be lifted or moved forward through hydraulic cranes at the two ends of the blade. The front wheels of the graders are articulated, while the rear wheels are ser under the control unit and motor unit.
Dumper trucks Construction equipment suppliers in India are widely used for their carrying loose material for construction site. They have back carriage, which can be uplifted by the hydraulic cranes to dump the material loaded on the trucks. These trucks vary in capacity from one ton to 80 ton. The choice of the particular dumper truck depends on the material quantity to be carried. Some dumper trucks have back carriages that can be tilted toward the sides to unload the loose material. The speed of the unloading is very fast in dumper trucks as they do not have any gate at the end of the back bumper. The slightly lifted portion of the back end keeps loose material inside the truck.
Bulldozer is a tracker with front blades that are raised and lowered as per the requirement of the job .The bulldozers use tracks and can be very stable for the job. They are used for heavy lifts. The tracks allow bulldozers to move on variety of ground surface easily. Some bulldozers come with blades, which push away materials to sides as bulldozer moves.
Before the start of the construction, Laboratory equipment suppliers in Delhi civil or geothermal engineers test for soil for its suitability for construction. The soil testing can be done on the spot with right equipments or in a laboratory.
Loaders and trucks are used to lift heavy machinery or loose materials used at the construction site. The trucks are used to carry materials like cements, iron loads or other such materials. The loaders along with cranes are used for lifting, and carrying heavy items from one place to other site of the construction site.
Types of trucks
Dump trucks are used for taking loose materials like sand, gravel or mud to the construction sites. These trucks have hydraulic cylinders fitted under the carriage to lift the carriage and unload all material at once in one go. These trucks can come in different configuration for different. Some trucks carry the dumping carriage with loose materials. The separate carriage has its own wheels but it is not fitted with any engine. The biggest advantage of this type of truck is that maximum load can be added without any affect on the maneuverability of the truck
Semi trailer end dump truck is combination of trailer and tractor. The trailer has hydraulic cylinders for dumping the loose material. This type of combination has advantage in rapid unloading the loose material.
The side dump trucks have facility to dump the material on the either left or right side. They do this by hydraulic ramps that title the body onto any side. These trucks often carry more loose material than other trucks.
The loaders are Construction equipment suppliers in India tractors with wheels and a square tilt bucket at the front end for lifting any material and carrying to short distance within the construction site. The front end is fitted with cylindrical arms for lifting and shifting the material or cements slabs.
Some loaders such as caterpillars have only front buckets and are known as front loaders. Some small front loaders are fitted with backhoe. These loaders are used for clearing way, removing debris, putting materials into trucks or laying pipes etc. loaders are fitted with wheels for faster mobility within construction area.
These are used by fitting small but heavy items or cartons by inserting the steel plates under the load. The plates are fitted in front of the wheel truck with driver’s seat. The fork lifters come in various sizes and capacities to serve the purpose of the client in construction industry.
Soil testing before Soil Testing Equipment Manufacturers in India construction of any building is essential to determine the capacity of the soil for construction of foundation of the building. The depth of the foundation depends on the building to be constructed on it and type of soil.
Over the decades the practice of soil testing has been accepted by the farmer community for getting complete knowledge of the soil for better yield and increased production per hectare. The increase in profit because of increase production motivates all land owners to hold soil testing. For proper soil testing, it is important that soil samples from various parts of the field or farm are taken and then mixed to get the genuine sample of that area.
Soil testing report will give exact fertilizer requirements to farmers. They will come to know the quantity of various fertilizers and nutrients both major and minor needed for the soil type. The water content is the soil is also determined by soil testing. This gives indication of the use of water needed for the particular crop. The low use of fertilizer reduces the crop yield and high use may damage the crop and also leads to waste of time and money for the former. It is also damages the environment due to runoff.
Thus, a farmer gets complete farm management tool to increase production, manage inputs accordingly, and control the damage to environment. The additional benefits are improvement in crop quality and maturity, high resistance to pet control, and use of effective pet resistance substance according to the soil type.
The application of limestone use can be known better with the use of soil testing on acid soils. The testing gives exact requirement for the limestone use. The soil testing can be done before the start of the cropping season, that can be in spring or start of the fall. The cost of soil testing is relatively soil test equipment suppliers in India low compared with cost of fertilizers and limestone, which keeps the overall expenses of a farmer low during crop season.
The reliable soil testing results depend on many factors such as method of taking soil for testing , steps involved in testing , techniques used for mixing samples of soil and fertilizers recommendation guidelines . Since levels of various nutrients in the soil cannot be visible seen, the use of professional soil testing analyst is important to expose the lack of various nutrients in a soil. The capability and desirability of a soil type for any particular crop can also be found by the soil testing methods.
The equipments Soil Testing Equipment Manufacturers in India used in soil testing locally available. These include sand pouring cylinder, soil cone penetrometer, and speedy moisture meter.
