Background technology
In the engineering exploration process, often to survey the following stratal configuration of river.Past generally is to utilize the drilling on waterways technology to carry out; In that The turbulent river crashes its way through, do not possess in the engineering of probing condition, can only rely on geological personnel to infer, so surveying accuracy is difficult to engineering demands.
After the engineering geophysics technical development, the physical prospecting personnel transfer to waterborne the test with the surface seismic method of exploration, and have obtained the breakthrough of method of exploration waterborne.Specific practice is: 1. set up a wire rope on the water surface, the decorating position of wire rope is physical prospecting survey line position; 2. geophone cable, signal wire, detonating cord etc. are suspended on the wire rope, arrange wave detector in the land, waterside; 3. row the boat the wire rope below by the design attitude placement blasting charge, again ship is drawn, so just obtain the seismologic record of a shot point to away from detonating powder behind the clear waters of the blasting charge; 4. by design shot point spacing, repeat the next item up operation, the shot point that designs on the water surface all detonates, and has promptly finished the seismic survey work of a survey line waterborne.
Above-mentioned method of seismic prospecting waterborne has obtained widespread usage in Hydraulic and Hydro-Power Engineering exploration in recent years, and has obtained exploration effects preferably, has solved the technical barrier of some explorations waterborne.But the limitation that it is arranged: ship must be arranged, and can only carry out seismic survey work in the waters that the water flows gently can navigate; In that The turbulent river crashes its way through, carrying place then can't be carried out seismic prospecting waterborne.
Summary of the invention
The objective of the invention is to, a kind of practicable seismic prospecting device waterborne is provided, make its can at no ship or The turbulent river crashes its way through carrying place is carried out seismic prospecting waterborne.
For achieving the above object, the present invention adopts following technical scheme: a kind of seismic prospecting device waterborne, comprise and to be strained and fixed at two on the bank wire rope, wave detector, cable, seismograph, the blasting charge, connect the top sheave frame of the pulley blocks that two pulleys form on wire rope by brace, on the wire rope of pulley blocks both sides, be with a plurality of " 8 " font suspension ring respectively, steel wire loop is gone up in the ring " 8 " font suspension ring, the center fixed of traction rope is on the brace of pulley blocks, the traction rope of brace both sides is fixed on respectively again on " 8 " font suspension ring of both sides successively, the two ends freedom of traction rope, making pulley blocks and 8 " the font suspension ring horizontally slip along wire rope under the affecting of two ends, left and right sides traction rope; and seismic cable freely passes between the following ring and two pulleys of " 8 " font suspension ring of the left and right sides; not with last; lower sheave contact; seismic cable is connected with wave detector with the bank seismograph respectively; quad one end freely passes the following ring of " 8 " font suspension ring of a side, and freely be through on the lower sheave of wire rope below, the blasting charge is bundled on the quad of pulley blocks lower sheave one end, and the quad other end is connected with blaster with the bank seismograph.
The length of described traction rope is greater than 2 times water surface width.
Described quad two cores are used for the explosion timing, two cores are used for the detonating powder bag.
Described wave detector is two, lays respectively at both sides on the bank.
The number of described " 8 " font suspension ring is decided according to water surface width, and the distance between two adjacent " 8 " font suspension ring of a side is a 3-7 rice.
Distance between two adjacent " 8 " font suspension ring of a described side is 5 meters.
The blasting charge of the present invention hangs, means of locomotion, in order to realize the waterside powder charge, to be transported to and to specify the shot point place, make blasting charge entry and detonate.With the binding or the monocycle hang of existing cable and wire rope, use " 8 " font suspension ring instead and hang.So both can guarantee suspension ring slippage smoothly on wire rope, can avoid the cable lay winding wire ropes again.Utilize the present invention, the seismic prospecting personnel are in the waterside terrestrial operation, just can at no ship or The turbulent river crashes its way through carrying place is carried out seismic prospecting waterborne.
