Background Art In the underground excavation head face production process, geological elements such as a geological structure, coal seam, top bottom plate and other geological elements are often required to be measured, by about 3m so that climbing, or standing on the belt can not be directly performed, or a worker can not measure related geological structure parameters, and potential safety hazards . exist. Content of the utility model In order to solve the above problem, the utility model provides a roadway roof geologic structure production appearance survey appearance. In order to achieve the above object, the technical scheme adopted by the utility model is : A top end rod of a top end rod, and a top end rod of a base, are perpendicular, to the middle rod, and a plane at which the base is located is connected, with an intermediate rod through, bent pipes, and the two ends of the base adopt 90° pipe, and are movably clamped with two clamping sleeves T . Further, the middle rod of the top rod, and the base adopt PC pipes, with an internal diameter 5cm. Further, the long 20cm, middle rod of the top end rod is 150m, base long 10cm. The utility model discloses following beneficial effect: has. The measuring rod has the advantages, low processing cost, simple structure, light, materials, portability and the like, and, measuring error in the underground actual geological writing observation process after the processing and forming reaches, or more, and has popularization and application values. 95%.

As shown 1- in FIGS. 2, of the utility model provides a tunnel roof geology construction shape appearance measuring apparatu, includes top pole 1, intermediate rod 2 and base 3, perpendicular 1, and base 2 adopts, pipe 3 and its both ends swing joint has two clamping sleeve pipe 2 and base, long 3 middle rod length 2 base 90° long 4 of, pipe 3 internal diameter through T elbow pipe, and the base plate both ends swing joint is connected 5. with middle rod 1, and both ends swing joint of seat 2, with middle rod 5cm. 3 and base 20cm, frame PC and 1 be connected with 150m, each 3 other 10cm. To the concrete embodiment, the top rod clings, to the roadway top plate so as to, represent the plane where the roadway is located, and the plane of, the instrument base is parallel with the laneway top plate to obtain the roadway top 3). plate (production. in the coal mine underground construction measurement process, of the present concrete embodiment, can obtain a, laneway top plate by measuring the shape of a plane in which the, base is located : 1, Measuring trend The long side of the compass is contacted, with the plane of the base, such as the compass-free long side, the edge parallel to the north-south direction is contacted, with the level and the level of (denotes the determined trend), at the center, of the compass level. 2, Measurement trend The compass north pole is directed towards the plane inclination direction, where the base is located, so that the compass short side (or the parallel side) of the compass and the plane contact, of the base are centered, compass placing level, and then, north needles are determined to be the required degree. 3, Measuring dip angle The long side of the compass or the edge parallel to the south and north direction is perpendicular, to the direction, and the level, of, peach shaped pointer on the dip angle dial is the required dip angle. It is to be noted that: or more of the preferred embodiments of the present invention have been presented, for those skilled in the art, and any modifications, equivalent substitutions, etc, which may still be made to those skilled in the art, are intended to be included, within the scope of the present invention, and the following detailed description, is not intended to limit the invention, or the scope . thereof. The measuring rod provided by the utility model has the advantages, that the machining cost is low, the structure is simple, the material is portable, the measuring error is less, and the accuracy reaches 90° or more, and the measuring rod has popularization and application values T or more in real geological writing and observation processes .
