具体实施方式Detailed ways
以下结合附图对本实用新型进行详细说明：The utility model is described in detail below in conjunction with accompanying drawing:
结合图1，本实用新型提供一种隧道衬砌检测用地质雷达天线支架，包括：底座2、连接件4、n个转换件以及n个手持螺管3；其中，n为自然数；In combination with Fig. 1, the utility model provides a geological radar antenna support for tunnel lining detection, including: a base 2, a connecting piece 4, n conversion pieces and n hand-held coils 3; wherein, n is a natural number;
其中，底座2的顶部通过连接件4与被支撑的探地雷达天线1固定连接；Wherein, the top of the base 2 is fixedly connected with the supported GPR antenna 1 through the connector 4;
底座2的底部均匀设置n个延伸部；每个延伸部的端部与一个转换件的一端铰接，转换件的另一端与一个手持螺管3可拆卸连接。The bottom of the base 2 is evenly provided with n extensions; the end of each extension is hinged to one end of a conversion piece, and the other end of the conversion piece is detachably connected to a hand-held coil 3 .
作为一种具体示例，延伸部为吊耳；转换件的上端为U形叉，U形叉设置有与吊耳通过螺栓铰接的通孔；转换件的下端为柱形螺母，手持螺管3的端部设置有与柱形螺母的内螺纹相匹配的外螺纹，手持螺管3通过螺纹连接方式与柱形螺母可拆卸连接。As a specific example, the extension part is a lifting lug; the upper end of the conversion piece is a U-shaped fork, and the U-shaped fork is provided with a through hole hinged with the lifting lug through a bolt; The end is provided with an external thread matching the internal thread of the cylindrical nut, and the hand-held coil 3 is detachably connected to the cylindrical nut through a threaded connection.
并且，手持螺管3由若干个螺管单元组成；其中，每个螺管单元的顶部均设置外螺纹，每个螺管单元的底部均具有内螺纹；并且，外螺纹和位于底部的内螺纹相适配，通过螺纹组装方式，将多段螺管单元串接组合，得到手持螺管3。通过该种结构，手持螺管在使用过程中，根据隧道地形情况，可非常方便改变手持螺管的长度，即：当需要增长手持螺管时，在最底部的螺管单元下方再安装多个螺管单元即可；当需要减少手持螺管长度时，将最底部的螺管单元卸下即可。And, hand-held solenoid 3 is made up of several spiral pipe units; Wherein, the top of each spiral pipe unit is all provided with external thread, and the bottom of each spiral pipe unit all has internal thread; And, external thread and the internal thread at the bottom Correspondingly, the multi-segment coil units are connected in series through thread assembly to obtain the handheld coil 3 . Through this structure, the length of the hand-held coil can be changed very conveniently according to the terrain conditions of the tunnel during use, that is, when it is necessary to increase the length of the hand-held coil, multiple The screw unit is enough; when the length of the hand-held coil needs to be reduced, the bottommost screw unit can be removed.
本实用新型提供的隧道衬砌检测用地质雷达天线支架，使用方法为：The method of using the geological radar antenna support for tunnel lining detection provided by the utility model is as follows:
(1)根据实际需要，灵活设置手持螺管的数量，例如，为3个；在图1中，即为安装3个手持螺管的示意图。(1) According to actual needs, flexibly set the number of hand-held coils, for example, 3; in Figure 1, it is a schematic diagram of installing 3 hand-held coils.
(2)由于转换件与底座铰接，因此，根据测试需要，调整每个转换件与底座之间的夹角，进而达到调整各个手持螺管与底座之间夹角的目的。(2) Since the transition piece is hinged to the base, the angle between each transition piece and the base is adjusted according to the test requirements, so as to achieve the purpose of adjusting the angle between each hand-held coil and the base.
(3)通过改变螺管单元的数量，调节每个手持螺管的长度；(3) Adjust the length of each hand-held coil by changing the number of coil units;
其中，以安装三个手持螺管的支架为例，由于每个手持螺管与底座夹角不同，因此，各个手持螺管的长度并不相同。Wherein, taking a bracket for installing three hand-held coils as an example, since the included angles between each hand-held coil and the base are different, the lengths of each hand-held coil are not the same.
(4)在完成上述准备工作后，以安装3个手持螺管为例，测试方法为：通过3个人进行测试，每个人手握手持螺管，3个人按一定角度站位后，将探地雷达天线抬起到检测位置，然后，3个人共同推动探地雷达天线沿检测测线移动，实现对该检测测线测试的目的。(4) After completing the above preparatory work, take the installation of 3 hand-held coils as an example. The test method is: test with 3 people. Each person holds the hand-held coil. The radar antenna is lifted to the detection position, and then three people jointly push the ground penetrating radar antenna to move along the detection line to achieve the purpose of testing the detection line.
在人工推动探地雷达天线沿检测测线移动的过程中，当遇到路面起伏较大的地形，可通过灵活改变每个手持螺管的长度，从而适应路面变化。另外，由于采用人工推动探地雷达天线，因此，人员可灵活的到达任何测试位置，具有移动范围更广的优点，相应的测量范围也随之增加，进而测量数据的完整度也大幅度提高，为隧道衬砌的长时间安全运行提供了有力的依据。In the process of manually pushing the ground penetrating radar antenna to move along the detection line, when encountering a terrain with large undulations on the road surface, the length of each hand-held coil can be flexibly changed to adapt to the change of the road surface. In addition, due to the manual push of the ground penetrating radar antenna, personnel can flexibly reach any test position, which has the advantage of a wider range of movement, and the corresponding measurement range is also increased, and the integrity of the measurement data is also greatly improved. It provides a strong basis for the long-term safe operation of the tunnel lining.
由此可见，本实用新型提供的隧道衬砌检测用地质雷达天线支架具有以下优点：结构简单、工作安全可靠、使用灵活以及成本低等优点，可满足恶劣环境下隧道壁衬砌质量的快速无损检测。It can be seen that the geological radar antenna support for tunnel lining inspection provided by the utility model has the following advantages: simple structure, safe and reliable operation, flexible use and low cost, etc., and can meet the rapid non-destructive inspection of tunnel wall lining quality in harsh environments.
