Description
Technical field
The utility model relates to Tunnel testing field, particularly a kind of tunnel-liner detections of radar servicing unit and utilize the tunnel-liner detections of radar car of this device.
Background technology
Tunnel construction, as disguised engineering, residing for it, geologic media is complicated and changeable, and construction process requirement is higher.In order to avoid unnecessary loss, ensure the safe reliability of Tunnel Engineering during runing, control Tunnel Engineering in construction process and hand over, the construction quality of being completed is particularly important.
At present, the construction of Tunnel Engineering mainly relies on tunnel monitoring measurement to carry out guiding construction.After constructing tunnel completes, need to evaluate constructing tunnel quality, and guide reparation to improve construction quality.Need fast, comprehensively, accurately to understand liner structure with or without indexs such as leakiness region of coming to nothing, sprayed concrete thickness, steel arch-shelf spacing in Tunnel testing process, and further guiding construction and monitoring construction quality.
As the main tool that tunnel lining structure detects, in the advance geologic prediction that geological radar has been widely used in Tunnel Engineering and quality testing.It has the features such as resolution is high, lossless detection, profile image are directly perceived, provides technical guarantee for evaluating Inspection of Tunnel Quality fast and accurately.
As shown in Figure 1, geological radar forms primarily of radar host computer A, transmission line B and radar antenna C, and radar antenna C is connected to radar host computer A by transmission line B; Wherein, radar host computer A is the central control system of detections of radar work, transmission line B has very strong self-shileding function, transmits coherent signal at radar host computer A and radar antenna C; Radar antenna C, for launching frequency electromagnetic waves (such as 200MHz, 400MHz, 900MH etc.) and receiving different medium reflection electromagnetic wave around tunnel.
When tunnel-liner detections of radar, geological radar by radar antenna C tunnel-liner surface internally transmission frequency be the electromagnetic wave of hundreds of megahertz.Just reflection and transmission can occur when electromagnetic wave runs into the interface of different medium, reflection wave returns to lining cutting surface, receive by radar antenna C and send to radar host computer A.Radar host computer A records electromagnetic wave and forms associated picture from the two way travel time being transmitted into reception, is analyzed after having detected by the quality of data post-processing software to tunnel lining structure.
Liner structure is the main body ingredient of Tunnel Engineering, the quality of its construction quality is directly connected to the integrally-built security and stability in tunnel, so must strengthen, to the detection of tunnel lining structure quality in construction and after completion, ensureing the safe reliability of Tunnel Engineering.Therefore, the detection of tunnel lining structure needs the multiple positions in tunnel to detect, and could carry out the evaluation of globality to tunnel lining structure.
At present, before tunnel-liner detections of radar, carry out the layout of survey line in advance, arrangement of measuring-line is arranged as master with longitudinal direction (tunnel bearing of trend), and laterally (tunnel interfaces) is arranged as auxiliary.As shown in Figure 2, the detection in tunnel at least needs layout 5 surveys line, lays respectively at the vault in tunnel, left and right haunch, left and right abutment wall, for larger three lanes tunnel, also need to increase by two surveys line at the haunch position in tunnel, running into the defective place of lining cutting also needs infill lines.In this area, vault is positioned at the top in tunnel, and in the radian relation of 45 degree between left and right haunch and vault, left and right abutment wall and left and right haunch are respectively in the radian relation of 45 degree.
Before tunnel-liner detections of radar, need to carry out detection setting-out process in advance, namely in tunnel, record a mileage mark every 5 ~ 10m.When preparing to detect, radar antenna is connected with radar host computer, and ensures to be in normal operating conditions, when detection, by radar antenna and lining cutting surface closely connected, and the bearing of trend in survey line position along tunnel carries out continuous detecting.
As shown in Figure 3, existing tunnel-liner detections of radar is the mode adopting manual measurement.Particularly, be, on locomotive 2, crane 3 is installed, at the top stationary work-table 4 of crane 3.During measurement, transmission line B is utilized radar host computer A and radar antenna C to be carried out being connected and ensure that geological radar equipment is working properly, locomotive 2 is driven to layout point (such as vault layout point, haunch layout point) below to be measured, the hand-held radar antenna C of survey crew stands on worktable 4, by crane 3, worktable 4 is raised the height of layout point close to be measured together with the staff that it is stood, staff radar antenna C will lift the tunnel-liner radar scanning carrying out this layout point to layout point place to be measured afterwards.Wherein, radar host computer A can be positioned in locomotive 2 as the mode in Fig. 3, or is positioned over the place that other is convenient to carry out tunnel lining structure detections of radar.
Although existing tunnel-liner detections of radar adopts the mode of manual measurement can complete the object of the set survey line of tunnel-liner being carried out to detections of radar, semi-artificial semimechanized testing process can only be met.And can not meet that personal security guarantee, data are authentic and valid, process requirement quickly and easily in the detection completely, its problem is mainly:
1) because tunnel cross-section area is large, arrangement of measuring-line position is high, no matter adopt high-altitude operation vehicle (such as mode shown in Fig. 3) or other mode such as scaffolded erecting in tunnel-liner detections of radar, testing staff needs to carry out work high above the ground and hand-held radar antenna is affixed on detection section, and need outfit 2 ~ 3 testing staff to assist mutually on narrow and small worktable, the impact by human factor in whole testing process is very large.
2) because tunnel-liner radar detection process is according to arranging the continuous detecting that survey line carries out along tunnel total length, when testing is carried out, in tunnel, site environment is poor, road surface is not in most cases owing to completing construction, cause road surface rugged and rough, and then the locomotive of operation meeting severe jolt in traveling process, speed is also difficult to remain a constant speed, and then station testing staff on the table cannot stablize center of gravity, very easily rock, arm also because of lift for a long time radar antenna aching and tired and make radar antenna depart from set line direction and can not fit tightly in lining cutting surface, and then the quality of radar image can not be ensured, the more important thing is that operating personnel rock and can cause serious threat to personal safety.
3) when locomotive run in traveling process road surface have barrier to need to detour time, the sensing range controlled due to the hand-held radar antenna of people is limited, and some lining section may be made to be detected.
Therefore, the correlation technique of existing tunnel-liner detections of radar need further improvement.
