Under reamed piles have mechanically formed enlarged bases that have been as much as 6 m in diameter.Under reamed piles are the most safe and economical foundation in Black cotton soil. Under reamed piles are bored cast in situ concrete piles having bulb shaped enlargement near base. A Pile having one bulb is called single under reamed pile. In its closed position, the under reamer fits inside the straight section of a pile shaft, and can be expanded at the base of the pile to produce the enlarged base. The cost advantages of under-reamed piles are due to the reduced pile shaft diameter, resulting in less concrete needed to replace the excavated material. Under reamed piles are of two types:
Pre-cast under reamed piles Pre-cast piles require specialized pile driving equipments. And its advantageous over in-situ cast pile because they don't need holes to be bored and the pile is already cast complete with the reinforcing steel in place.
In-situ cast under reamed piles It is used to replace soil removed by drilling rather than occupying the space of displaced soil as in driven piles and thus, it mostly relies on end-bearing capacity of the earth layer at the drilled depth.
Touch piles is a temporary or permanent retaining wall commonly used for excavations in urban areas. Touch piles are most suitable in conditions where well constructed walls will not result in subsidence such as over-consolidated clays, soils above the water table if they have some cohesion, and free draining soils which can be effectively dewatered, like sands. Touch pile consist of multiples piles spaced apart from each other to support a change of elevation. Touch pile Shoring is very versatile because the size of the piles and the spacing between them can be adjusted to site soil conditions.
Lime and Sand pile service is one of our best and commonly undertaken service by our company. We take this service for both commercial as well as domestic projects. This is most widely used service. There are lots and lots of competition for this service and we have done a lot and succeeded in the particular service. Sand and lime pile are used for both domestic as well as commercial building foundations. Sand and lime pile service helps in making a strong foundation by avoiding cracks and settlements in the building. We have gained a very good reputation by providing high quality service at competitive prices. We have completed number of projects and given them thriving end.
Tractor mounted hole is variously used in most of the area and it's commonly used one now a days. We using this in residential plots, hospitals, multicomplex, shopping malls etc. Using traction mounted pile large dia pile holes are made, this is widely accepted method because it is highly compact, economical and faster in work. Main advantage of tractor mounted pile is that it doesn't produce any vibrations or reporting sound. This type of pile is widely used in big construction to make a strong foundation.
Bored pile foundations are used for tall buildings or massive industrial complexes that can bear the load of thousands of tons, most probably in unstable or difficult soil conditions. Bored pile is another type of reinforced concrete pile, which is used to support high building producing heavy vertical loads. Bore Pile Foundation has a large range of equipment available for the execution of bored piles ranging from limited headroom equipment to modern all hydraulic tracked machines capable of drilling holes in soil and rock. Soil and or rock is removed using purpose designed drill tools including soil and rock augers, drilling buckets, core barrels, and down hole hammer drills. Drilling to depths of up to 60 meters and to diameters from 300mm to in excess of 2 metres is possible in soil and rock. Various methods of support for the sides of bored piles during construction are available. These can be selected to suit the type of formation being drilled, the ground water regime encountered, and site environmental constraints. The advantage of bored piling is because the drilling method produces little vibration and lower noise level.
Compressor Pile is variously used in most of the area and it's commonly used one now a days. We using this in residential plots, hospitals, multicomplex, shopping malls etc. Using traction mounted pile large dia pile holes are made, this is widely accepted method because it is highly compact, economical and faster in work. Main advantage of tractor mounted pile is that it doesn't produce any vibrations or reporting sound. This type of pile is widely used in big construction to make a strong foundation.
AXIAL COMPRESSION TEST WITH KENTLEDGE BLOCKS
Load Test shall be performed when concrete has reached its required strength i.e. 28 days strength. The axial compressive loads test should be done as per IS code 2911 part IV (latest revision). Pile Loading Test shall be performed by applying compression load to the pile top by means of a hydraulic jack against rolled steel joist (RSJ) or suitable frame capable of providing reaction and the settlement shall be recorded by suitably positioned dial gauges.
VERTICAL LOAD TEST USING SAND PACKS
The test can be initial or routine test .The load is applied in increments of 20% of the estimated safe load. Hence the failure load is reached in 8-10 increments. Settlement is recorded for each 45 Settlement is recorded for each increment until the rate of settlement is less than 0.1 mm/hr. The ultimate load is said to have reached when the final settlement is more than 10% of the diameter of pile or the settlement keeps on increasing at constant load.
LATERAL LOAD TEST
When performing lateral load tests on deep foundations, it is desirable to obtain horizontal displacement versus depth profiles. These profiles can be used in conjunction with lateral load versus displacement curves to calibrate lateral pile analysis programs. In addition, the displacement versus depth curves can be used to determine bending moment versus depth profiles.
PULL OUT TEST
This test method covers determination of the pullout strength of hardened concrete by measuring the force required to pull an embedded metal insert and the attached concrete fragment from a concrete test specimen or structure. The insert is either cast into fresh concrete or installed in hardened concrete. This test method does not provide statistical procedures to estimate other strength properties.
A jack is a device that uses force to lift heavy loads. The primary mechanism with which force is applied varies, depending on the specific type of jack, but is typically a screw thread or a hydraulic cylinder. Jacks can be categorized based on the type of force they employ: mechanical or hydraulic.
Dial indicators are one of the primary measuring tools used in precision engine building. They are typically used to measure deck clearances, crankshaft thrust and straightness, lifter travel and other measurements that involve the distance between two surfaces or small amounts of component travel. Dial indicators typically measure ranges from 0.25mm to 300mm (0.015in to 12.0in), with graduations of 0.001mm to 0.01mm (metric) or 0.00005in to 0.001in (imperial/customary).
Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges. A pressure gauge is used to measure the pressure in a vacuum—which is further divided into two subcategories: high and low vacuum (and sometimes ultra-high vacuum). The applicable pressure ranges of many of the techniques used to measure vacuums have an overlap. Hence, by combining several different types of gauge, it is possible to measure system pressure continuously from 10 mbar down to 10-11 mbar.
The Pile Integrity Tester gives peace of mind that a pile or shaft is free of major cracks and voids, prior to construction of the superstructure. It may be used on most concrete or wood foundations. The PIT may also be used to test pile integral in the structure, such as those supporting existing bridges or towers, and may assess their length. The PIT performs wave equation-based non-destructive foundation investigation known as low strain impact integrity tests or low strain dynamic tests. These tests may be performed by the pulse echo or transient response methods.
