Gaveshana Geosciences Private Limited Delhi

We manufacture different range of the transmission line equipments. These are used in the various power and electric transmission line towers.

We are offering ground penetrating radar (gpr) is a totally non-destructive technique to produce a cross section profile of subsurface without any drilling, trenching or ground disturbances. The profiles are used for detecting buried utilities, such as, pipes, cables, etc in totally non-destructive manner. Additionally, subject to requirements, we also use cable & pipe locators, and for precise definition of locations, we use dgps and electronic total stations. The system operates by detecting subsurface changes in em properties (dielectric permittivity, conductivity, and magnetic permeability) which in a geological setting are functions of soil and rock material, water content, and bulk density. Data is acquired by transmitting high frequency electromagnetic (em) signals into the ground which are reflected from various boundaries possessing em property contrasts. The equipment receives the reflected waves over a selectable time range and displays them in real time on screen. The reflected wave data is also saved in appropriate memory for later processing and interpretation. Gpr measurements are used in geologic, engineering, hydrologic, and environmental applications. The company provides the following services using gpr: (a) mapping geologic conditions, such as, depth to bedrock, depth to water table, depth and thickness of soil strata on land and under fresh water bodies, location of subsurface cavities and fractures in bedrock. Mapping landfills and trench boundaries, and contaminants (b) location of buried utilities, such as, pipes (metallic and non-metallic), electric cables (induction locator is further used to identify live cables), drums, tanks, sewers, and boulders. (c) conducting investigations for archaeological and forensic applications. (d) conducting studies, such as, roads and railroad track-bed studies, and highway bridge scour studies. (e) inspection of brick, masonry, and concrete structures.

We are offering seismic cross hole test. The seismic cross-hole survey yields detailed measurements of in-situ compressional and shear wave velocities in cased boreholes typically spaced 3 to 6 m apart. The cross-hole survey provides information pertinent to the seismic wave velocities of the material in question. These velocities are used as input into site specific static dynamic analyses, or for computing shear modulus, young’s modulus, and poisson ratio for material characterization or for determination of vertical and lateral heterogeneity existing at site. Seismic cross-hole survey uses two or more boreholes to measure wave propagation velocities along horizontal paths. The simplest cross-hole survey configuration consists of two boreholes, one of which contains an impulsive energy source and the other a receiver. By fixing both the source and the receiver at the same depth in each borehole, the wave propagation velocity of the material between the boreholes at that depth is measured. By testing at various depths, a velocity profile can be obtained. When possible, use of more than two boreholes is desirable to minimize possible inaccuracies resulting from trigger time measurement, casing and backfill (material placed between the casing and the borehole wall) effects, and site anisotropy.

Soil profiles, as we know, vary considerably from one location or region to the next, depending on geology, hydrology and climate.Hence, soil testing becomes an essential part of a fertility program and to profitable crop production.

Quality being the sole concern, we offer functionally updated array of Vane Shear Apparatus that are quality assured and are corrosion resistant in nature. Our entire product range has high shear strength and is performance based. The Vane Shear Apparatus are known for their quality assurance.

We believe in discharging our services ourselves. We neither outsource our work to a third party, nor do we perform with tools and equipment hired or borrowed from a third party. In the same vein, we never lend our equipment to others on hire.
