Description
Technical field
The invention belongs to radar wave absobing field, specifically, relate to the real-time sounding system of a kind of mark band based on the radar exploration technique.
Background technology
At present, the management method for existing underground utilities mainly contains two kinds: one is ground identity management, that is: arrange warning thing on the ground; One is in underground identity management, that is: above underground utilities, whereabouts mark band is laid at 30-70 centimetre place, and when excavating, mark band folding part with digging tool passive open, can be dragged to ground again, plays prompting or warning function to digger.Mark band to the distance on ground is excavated the degree of depth of pipe trench when pipe canal digging also strict regulation, and specify that the distance taking pipeline from mark to, the distance that mark takes ground to is also substantially clear.But the serviceable life of underground utilities will reach 30-50, the meeting that the pipeline that quality is good, maintenance puts in place has was more than 100 years.And As time goes on because personnel repeatedly switch, join the loss that not in place caused data are omitted, human factor excavates the marker caused repeatedly, add natural cause as, the part that the change of the shallow topsoil of the earth, underground sandy soil cause because of water or gas effect runs off, and all can cause the inefficacy of existing identity management mode.
No matter existing identity management mode, be ground or underground, all could not solve the real-time mark to underground utilities current state.
Summary of the invention
For solving the problem, the invention provides the real-time sounding system of a kind of mark band based on the radar exploration technique, indirectly can infer according to the buried depth of mark band and change in location and soil layer situation of change around underground utilities, to detect for pipeline safety and construction excavation provides reference frame.
The real-time sounding system of mark band based on the radar exploration technique of the present invention, comprise pipeline, be laid on mark band above pipeline, and radar detector, it is characterized in that, encapsulation foil aluminium foil in mark band, described radar detector comprises emitting radar waves unit, radar wave receiving element, data record unit, data processing unit and display unit;
Emitting radar waves unit, for launching radar wave;
Radar wave receiving element, for receiving the radar wave of returning from the thin layer aluminium foil back reflection mark band;
Described data record unit, launches the time t of radar signal for recording emitting radar waves unit
1accept to receive the time t that unit accepts to receive the radar wave reflected with radar wave
2; And by this information transmission to data processing unit;
Described data processing unit, accepts the signal that data record unit transmission comes, obtains the mean propagation velocity V of radar wave in soil by the algorithm routine preset
t, and then obtain the degree of depth h=(t on mark band distance ground
2-t
1) V
t/ 2;
Described display unit, in order to the real-time deep h of the mark band of displaying data in real-time processing module feedback.
Descend whereabouts mark band in combination, in mark band, encapsulate one deck aluminium foil, utilize this sounding gear can realize the real-time measurement of whereabouts mark band buried depth with aluminium foil.Mark band is frivolous pliable and tough, be laid on 30-70 centimetre place above pipeline, extend along pipeline, around pipeline due to natural cause or pipeline self leak cause the sand running-down of pipeline periphery, the change of sub-surface structure time, mark band above pipeline also can change with the change of around soil layer, or drift or fracture.Sounding gear is used to detect whereabouts mark band, if find, the position of whereabouts mark band or buried depth there occurs suddenly huge variation, even cannot detect the depth data of mark band, then be likely that the soil layer construction of underground herein there occurs violent variation, or form underground cavity.Now, must enforce martial law this region, carry out excavation investigation immediately, the accident of preventing disasters property occurs.
Emitting radar waves unit launches electromagnetic wave, radar wave receiving element receives the electromagnetic wave signal be reflected back, in detection process, data record unit automatically records radar emission and goes out the time of detectable signal and receive the time of the electromagnetic wave signal arrival that the aluminium foil layer in mark band is reflected back.Built-in several radar wave speed calculation procedure in this sounding gear, as adopted Method of Dielectric Coefficient, reflectance supervisor, and mark takes the algorithm routine of ground distance to; According to the residing most suitable radar wave speed account form of environmental selection at that time, radar wave speed can be calculated efficiently, for depth calculation provides authentic data.Can detect the change of pipeline periphery soil layer, according to the situation of change of mark band position and buried depth, heuristically whether underground pipelines periphery soil layer there occurs large change, once change, carry out excavation investigation, and safeguard.
Preferably, described radar wave frequency is 25MHz ~ 2GHz.
Preferably, the described mark band being packaged with thin layer aluminium foil is a kind of elongated shape strip, and its width is 10 ~ 20cm, is preferably 15cm.Radar detection has special requirement to detected object, and the size of detected object is at least 1/10 of buried depth, adopts the ripple thin layer aluminium foil of this width can meet radar detection and requires and improve the precision measured in real time.
Compared with prior art, the invention has the beneficial effects as follows: this device can be utilized to realize descending the real-time deep of mark band to measure over the ground, and can directly in device display screen display; Only use one deck thin layer aluminium foil just present underground mark band to be become underground environment barometer, sounding gear is combined with aluminium foil mark band, and achieve the measurement descending mark band real-time status over the ground, investment cost is low, and cost is low, economic and practical; Method of operating is simple, and the hand-held sounding gear of operating personnel is patrolled along mark band, just can check the buried depth of mark band at that time at any time, judge the situation of underground mark band surrounding enviroment, use manpower and material resources sparingly with this.
