Abstract
The invention relates to a hammering shock exciting rod which is a tool for exciting shock in seismic exploration. An integral shock exciting rod consists of a metal rod body, a metal disk plate and a hammering head, wherein the length of the metal rod body is 20-30cm, and the diameter is 2.5-4.5cm; one end of the rod body is provided with a round metal disk plate with a diameter of 5-10cm and the thickness of 0.5-1.5cm or a square metal disk plate the side length of which is 5-10cm or a polygonal metal disk plate the side length of which is 3-6cm, while the other end is manufactured into the hammering head. The shock exciting rod and a striking hammer are respectively connected with a receiving host by using leads to form a circuit, and the circuit forms a loop in an instant when the striking hammer strikes the hammering head so as to ensure that potential difference output by the receiving host forms a short-circuit pulse used as a starting signal of the receiving host and a time marker when the timing is 0.
Description
Technical field
Hammering shock exciting rod is a kind of instrument of explosive source in seismic prospecting, possession seismic exploration utensil technical field.
Background technology
Current, shallow seismic exploration uses the hammering explosive source more, all uses the backing plate of plastics, resin or a steel, places on the ground or the surface of other media that impulse.The sledgehammer that exciting is used impacts and produce seismic wave on backing plate.This mode that impulses is available in many cases, but when impulsing on tunnel tunnel face or abutment wall, backing plate be difficult to be shelved on be bordering on vertical to rough scar on; On the road surface of the cement in city, pitch, brick, backing plate takeoffs after by hammering, can produce 2 vibrations, put backing plate again, wastes time, and influences testing speed and construction safety.
Summary of the invention:
The purpose of this invention is to provide a kind of energy and strengthen the directionality that impulses, make under the seismic energy of (when detecting forward for to the dead ahead) more concentrated, simultaneously when impulsing on the rock face of tunnel tunnel face or on city pitch or concrete or brick paving, impulse more fast, safely, guarantee the hammering shock exciting rod of testing quality and speed.Technical scheme of the present invention is: the metal barred body that uses length L=20～30cm, a diameter r=2.5～4.5cm, the body of rod one end is shaped on circular or the square of four limit length of side H=5～10cm or the polygonal metal plate of length of side H=3～6cm of a diameter R=5～10cm, the thickness h of plate=0.5～1.5cm.Metallic rod body and metal plate are made one.When shock exciting rod uses, metal plate bottom surface is placed in ground or other measured medium surfaces, beats with 4 pounds median size hammering, the hammering head on shock exciting rod top, hammering top produces the vibrations that impulse.This by the impulsing of hammering metal shock exciting rod, can excite the abundant seismic wave of wideband and radio-frequency component, can make the energy that impulses more concentrated along the direction of shock exciting rod; Impulsing on the rock face of tunnel tunnel face or on the abutment wall or simultaneously on city pitch or concrete or the brick paving and testing on the scar at exposed bedrock, comparatively convenient.
Advantage of the present invention is: 1. the seismic energy on the hammering excitation direction is concentrated, and seismic wave propagation is dark, and is effective; 2. make easily, easy to use, safe; 3. on pitch, concrete, brick paving and rock face, impulse and install shock exciting rod and hammering is easy.

Embodiment: as shown in Figure 1, 2, 3, shock exciting rod is made by metal barred body (1), metal plate (2) and hammering head (3), metal barred body (1) length L=20～30cm, diameter r=2.5～4.5cm, make the circle of a diameter R=5～10cm or the polygonal metal plate (2) that four edge lengths are square or the length of side H=3～6cm of H=5～10cm at metal barred body (1) one end, thickness h=0.5～the 1.5cm of plate (2), metal barred body and metal plate are made one, and the other end of metal barred body is made hammering head (3).
As shown in Figure 4, the user mode of shock exciting rod in the tunnel: with the plate (2) of shock exciting rod, push against the rock at the measuring point place of tunnel tunnel face, receiving instrument main frame (5) respectively by two leads (6), (7) and the body of rod that impulses (1) with impact hammer (4) and be connected.With impacting the hammering head (3) that hammer (4) impacts the shock exciting rod top, in the moment that impacts hammer (4) contact hammering head (3), two leads (6) and (5) of drawing from receiving instrument (5) form path with metallic rod body (1), hammer (4), the short-circuit condition of the circuit that forms by (1), (4), (6), (7), the feasible current potential of always supplying with by instrument is given short circuit pulse signal of instrument, make to receive the instrument startup, and counted for 0 time.
Claims (1)
1. hammering shock exciting rod, it is characterized in that: shock exciting rod is made by metal bar, metal plate and hammering head, metal bar length L=20～30cm,, diameter r=2.5～4.5cm, end at the metal barred body is shaped on the circle of a diameter R=5～10cm or the polygonal metal plate that four edge lengths H are square or the length of side 3～6cm of 5～10cm, the thickness h of plate=0.5～1.5cm, the other end of metal barred body is made the hammering head, shock exciting rod with impact hammer and be connected with the receiver main frame with lead respectively.
