Description

Self-drilling type shearing wave proving installation
Technical field
The utility model relates to a kind of self-drilling type shearing wave proving installation, belongs to engineering exploration constructing device technical field.
Background technology
Produce wave of compression (claim not only P ripple) and shearing wave (but also claiming S ripple) by focus, received by three-component seismometer through soil layer, the distance of propagating according to ripple and calculate the velocity of wave of Site Soil while walking, and then the engineering properties of evaluation Site Soil.
The Main Function of shearing wave is the division of earthquake community, judgement, the calculating of site soil layers dynamic modulus of elasticity etc. of site liquefaction.Traditional shearing wave test mode, for first adopting machine drill preexisting hole, is then put into hole by testing tool, starts test from bottom to top from bottommost.Adopt this kind of method of testing, the problem of existence is: 1, Completion of Drilling Hole quality is too poor, and equipment cannot be put into assigned address; 2, in the process of construction, borehole collapse, equipment is embedded in hole.
Summary of the invention
The purpose of this utility model is the problem that the place apparatus that causes due to boring problem when solving the test of shearing wave in prior art is measured, and provides a kind of device simple, self-drilling type shearing wave proving installation easy to use.
The utility model adopts following technical scheme: a kind of self-drilling type shearing wave proving installation, comprise general extension rod, described general extension rod bottom is connected with drill bit injection bar, on the sidewall of described drill bit injection bar, be provided with longitudinal fluting, described general extension rod and drill bit injection bar are provided with the cavity of perforation, in described cavity, be provided with concussion generator and weight, described concussion generator adopts cable to be connected with weight, the described cable other end is located at outside the cavity of general extension rod, and the cable other end is connected with the operation of concussion generator and memory storage.
Further, the length of described general extension rod is 1m.
Further, the top of described general extension rod is provided with static pressure perforation device.
Further, the bottom of described general extension rod and drill bit injection bar adopt and are threaded.
Further, the top of described drill bit injection bar is set to cone-shaped.
The utility model is simple in structure, easy to use, and assembling is convenient, can directly bring to building site and be assembled to according to demand suitable length; Pore-forming is synchronizeed and is carried out with test, avoids the not high possibility that cannot test and be buried of hole quality; Recycling after device is detachable.

Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As Figure 1-Figure 4, a kind of self-drilling type shearing wave proving installation, comprise general extension rod 1, general extension rod 1 bottom is connected with drill bit injection bar 2, the bottom of general extension rod 1 and drill bit injection bar 2 adopt and are threaded, the top of drill bit injection bar 2 is set to cone-shaped, on the sidewall of drill bit injection bar 2, be provided with longitudinal fluting 2-1, general extension rod 1 and drill bit injection bar 2 are provided with the cavity of perforation, in cavity, be provided with concussion generator 3 and weight 4, concussion generator 3 adopts cable 5 to be connected with weight 4, the other end of cable 5 is located at outside the cavity of general extension rod 1, cable 5 other ends are connected with the operation of concussion generator and memory storage 6, the length of general extension rod 1 is 1m, after can some general extension rods 1 being threaded connection according to actual measurement, be connected with drill bit injection bar 2 again, the top of general extension rod 1 is provided with static pressure perforation device 7.
Principle of work: after self-drilling type shearing wave proving installation has been assembled, with static pressure perforation device 7 by vertical with drill bit injection bar 2 general extension rod 1 be pressed into underground, after the degree of depth of specifying, the operation of concussion generator and memory storage 6 send signal to concussion generator 3 by cable 5, make to shake the left and right concussion in the hole of the groove 2-1 of subterranean drill bit injection bar 2 formation of generator 3 and weight 4, produce shearing wave, the operation of concussion generator and memory storage receive shearing wave signal on ground, progressively deepening the degree of depth tests, after experiment, extract equipment by static pressure perforation device 7.
