A seismic sensor, having a body which incorporates means for detecting and/or measuring waves, and, in the extension of said body, a tip for insertion into the ground, said tip extending between an upper end and a lower end, wherein said tip has at least two wings which together give said tip a V-shaped profile, said wings having between them at least one cavity which extends from said upper end to close to said lower end.
A seismic sensor for detecting ground movement, said seismic sensor comprising:
An insertion tip designed to be attached to a seismic sensor, comprising at least two wings which together give said tip a V-shaped profile, said wings having between them at least one cavity which extends from an upper end of said tip to close to a lower end of said tip, said wings comprising retaining means for retaining said tip in the ground, said retaining means comprising a widening of said wings in a direction of said lower end.

This application claims the benefit of French Patent Application No. FR 07/04819, filed on Jul. 4, 2007, which application is hereby incorporated by reference in its entirety.
1. Field of the Invention
The field of the invention is that of seismic data acquisition. More specifically, the invention relates to the design of the insertion tips with which seismic sensors are provided, in order to allow them to be installed and/or held in the ground.
FIG. 1 is a schematic representation of a seismic sensor tip according to the invention.
FIG. 2 is a side view of a seismic sensor equipped with a tip according to the invention.
FIG. 3 is a side view of an insertion tip according to the invention.
In general, when designing insertion tips, the aim is to achieve a double objective: the ease of installation and the quality of the coupling.
The insertion of the sensor and the stability of the coupling are defined by resistive forces generated by the tip on the ground.
Thus, in order to facilitate insertion, it is necessary to limit the penetration force and to create “open” zones of the ground making it possible to enlarge the hole by locally packing down the ground.
