Description
Technical field
The utility model relates to a kind of geologic prediction signal triggering device, relates in particular to a kind of tunnel TSP advance geologic prediction signal and leads to flip flop equipment more.
Background technology
Advance geologic prediction in the constructing tunnel process is the important foundation geological information of information-aided construction and design; Can in time forecast the front of tunnel heading unfavorable geology and contain the permeable structure situation through advance geologic prediction; And then adopt an effective measure in advance; Prevent and treat the generation of geological disasters such as gushing water, prominent mud, landslide, guarantee the safety of constructing tunnel.Tunnel method of seismic exploration (TSP) is one of main method of the long-term advance geologic prediction of construction period non-destructive, has become one of most widely used forecasting procedure in the tunnel information construction of growing up.
The TSP advance geologic prediction signal triggering mode that adopts at present has certain limitation, mainly be because:
1. adopt traditional approach to execute when making the TSP advance geologic prediction, need the process 24 times of repetition " powder charge-big gun hole water filling-wiring-detonate-receive ".
2. under the factor affecting such as light is gloomy in the tunnel, possibly cause powder charge, wiring, detonate when water filling personnel in big gun hole do not withdraw from the safety zone as yet, cause security incident, and lose time, influence constructing tunnel.
The utility model content
The purpose of the utility model is exactly in order to address the above problem; A kind of tunnel many messengers of TSP advance geologic prediction flip flop equipment is provided, and it has the characteristics of disposable completion " powder charge-big gun hole water filling-wiring " process, and by many logical trigger controls; Automatically accomplish the Preset Time process of repeatedly " detonating-receive " at interval; Can guarantee to greatest extent that in advance geologic prediction explosive initiation process, powder charge, the water filling of big gun hole and wiring personnel remove into the safety zone, and then guarantee safety; And realized the Digital Control that many messengers trigger, promptly through triggering automatically and receiving seismic signal, practiced thrift the forecast time, the degree that influences constructing tunnel is little than traditional mode.
To achieve these goals, the utility model adopts following technical scheme:
A kind of tunnel TSP advance geologic prediction signal leads to flip flop equipment more; Comprise flip flop equipment, described flip flop equipment comprises many logical triggers, and how logical trigger is connected with main frame; Many logical triggers also are connected with initiator, and how logical trigger is connected with at least one detonator through cable.
Described many logical triggers; It comprises 1 timing circuit and 1 circuits for triggering; Described circuits for triggering are connected with timing circuit, and timing circuit is connected with initiator through the triggering signal input port, comprises at least one signal triggering unit in the described circuits for triggering; At least one signal triggering unit in the circuits for triggering is connected with main frame and at least one detonator respectively.
Described cable is a Stranded cable.

1. detonators wherein, 2 initiators, 3. many logical trigger, 4. main frame, 5. trigger, 6. timing circuit, 7. circuits for triggering, 8. signal triggering unit.
The specific embodiment
Among Fig. 1, be the connection layout of prior art, trigger 5 is connected with main frame 4, and trigger 5 also is connected with initiator 2, and trigger 5 is connected with detonator 1 through lead.
Among Fig. 2, Fig. 3; A kind of tunnel TSP advance geologic prediction signal leads to flip flop equipment more, comprises flip flop equipment, it is characterized in that; Described flip flop equipment comprises many logical triggers 3; Many logical triggers 3 are connected with main frame 4, and how logical trigger 3 also is connected with initiator 2, and how logical trigger 3 is connected with at least one detonator 1 through cable.
Described many logical triggers 3, it comprises 1 timing circuit and 1 circuits for triggering, comprises 24 signal triggering unit in the circuits for triggering again; Detonator 1 is connected with the signal triggering unit.
Described cable is a Stranded cable.
Excite the signal triggering order and the time interval in the hole through many logical triggers 3 are preset, to explosive in 24 holes carry out successively, the controlled triggering of digitlization, realize the Digital Control of signal triggering and receiving course.
Though the above-mentioned accompanying drawing that combines is described the specific embodiment of the utility model; But be not restriction to the utility model protection domain; One of ordinary skill in the art should be understood that; On the basis of the technical scheme of the utility model, those skilled in the art need not pay various modifications that creative work can make or distortion still in the protection domain of the utility model.
