[0029] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0030] like Figure 1-2 As shown, a coordinate elevation layout measuring device for road engineering includes an upper cover 1, an upper tube 2, a lower tube 4, a base 5, a reinforcement frame 6, a sliding device 7 and a measuring device 8. The bottom end of the upper cover 1 is fixedly connected to the base 5 through the upper tube 2, the sleeve 3 and the lower tube 4 in sequence. The base 5 can be placed underground by hammering the upper cover 1 or digging a hole. The upper tube 2, the sleeve 3 and the lower tube 4 are all hollow tube structures. The sliding device 7 is sleeved on the outer periphery of the upper tube 2. The sliding device 7 can slide up and down along the outer periphery of the upper tube 2. A measuring device 8 is arranged on one side of the sliding device 7. The staff can mark the elevation of the roadbed through the measuring device 8. The reinforcement frame 6 is located on the outer periphery of the lower tube 4 and above the base 5, and is used for the stable structure of the entire measuring device to prevent tilting.

[0031] like Figure 3As shown, the reinforcement frame 6 includes a ring shaft 61, a support plate 62, a collar 63 and a frame rod 64. The cross-sections of the collar 63 and the ring shaft 61 are both annular structures. The ring shaft 61 passes through a plurality of frame rods 64 and a plurality of support plates 62. Each frame rod 64 is located between two adjacent support plates 62. The top of each support plate 62 is fixedly connected to the bottom end of the collar 63. The ring shaft 61, the support plate 62, the collar 63 and the frame rod 64 are all located on the periphery of the lower tube 4. During construction, the staff inserts the reinforcement frame 6 into the lower tube 4 and lets the frame rod 64 hang naturally. After the lower end of the frame rod 64 touches the base 5, it extends to the periphery due to the interference of the outer edge of the base 5. The staff hammers the support plate 62 from top to bottom. One end of each frame rod 64 is fixed to the ring shaft 61, and the other end gradually flattens, thereby achieving the effect of fixing the base 5.

[0032] The top of the rack rod 64 is a spherical structure to prevent the rack rod 64 from interfering with the bottom of the support plate 62 when rotating along the ring shaft 61. The bottom of the rack rod 64 is a frustum structure to facilitate construction work by the staff. The ring shaft 61 passes through the tops of several rack rods 64.

The bottom end of each rack rod 64 slides toward a first arcuate groove 54. On the one hand, the first arcuate groove 54 serves to limit the rack rod 64 to prevent the rack rod 64 from being hit by a hammer and entering the ground in an uncontrollable direction. On the other hand, the slope setting in the first arcuate groove 54 enables the rack rod 64 to slide toward the ground at an angle to avoid abrupt sliding that affects construction and damages components.

[0035] like Figure 6 As shown, the sliding device 7 includes a first clamp 71, a second clamp 72, a third clamp 73 and a first fastening bolt 74. The cross-sections of the first clamp 71 and the second clamp 72 are both T-shaped structures and are symmetrically arranged. The cross-section of the third clamp 73 is an arc structure. Bolt holes are provided at both ends of the first clamp 71 and both ends of the second clamp 72. A second arc groove 75 is provided on one side of the first clamp 71 and one side of the second clamp 72. One end of the first fastening bolt 74 is located on the other side of the first clamp 71, and a measuring device 8 is installed on the other side of the second clamp 72. The third clamp 73 is located in the second arc groove 75 of the first clamp 71. The other end of the first fastening bolt 74 passes through the first clamp 71 and the third clamp 73 in sequence and is fixedly connected to the inner side of the third clamp 73. The outer periphery of the upper tube 2 is located on the inner side of the third clamp 73 and the inner side of the second clamp 72.

[0036] like Figure 7 As shown, the measuring device 8 includes a base plate 81, a straight plate 82 and a slide ruler 83. One end of the straight plate 82 is fixedly connected to one side of the second clamp 72 through the base plate, and the other end is provided with a slide hole. The slide ruler 83 is located in the slide hole, and scales are distributed on the slide ruler 83. The staff puts the slide ruler 83 into the slide hole, and one end of the slide ruler 83 falls to the bottom, which is used to check the horizontal height value.

[0037] The measuring device 8 also includes a cover plate 84, a card plate 85, a clamping bolt 86, a spring 87 and a second fastening bolt 88. The cross-section of the card plate 85 is a U-shaped structure. One side of the card plate 85 is fixedly connected to one side of the second clamping hoop 72 through the bottom plate 81, and a slide is arranged on the inner wall of the other side. A card plate is arranged at one end of the straight plate 82, and one end of the straight plate 82 is clamped to the slide through the card plate. The upper end of the card plate 85 is installed with the cover plate 84 through a plurality of clamping bolts 86. One end of each clamping bolt 86 is located below the card plate 85, and the other end passes through the card plate 85, the straight plate 82 and the cover plate 84 in turn, and is fixedly connected to the upper end of the cover plate 84.

[0038] Installation and use process of a road engineering coordinate elevation layout measuring device:

[0039] The staff bolts the two ends of the lower pipe 4 to the upper cover 1 of the base 5, and then hits the top of the upper cover 1 with a pile driver to hammer the base 5 into the ground. Then the upper cover 1 is removed, and the reinforcement frame 6 is inserted into the outer periphery of the lower pipe 4. The pile driver with the ring hammer hits the collar 63. After the lower end of the rack rod 64 touches the base 5, it is extended to the periphery by the interference of the first arc groove 54. On the one hand, the first arc groove 54 plays the role of limiting the rack rod 64 to prevent the rack rod 64 from being driven into the ground in an uncontrollable direction by the hammer force. On the other hand, the first arc groove The slope setting inside 54 allows the rack 64 to slide underground at an angle to avoid abrupt sliding that affects construction and damages components. The staff stops hammering after observing that the bottom end of each support plate 62 contacts the upper end of the seat body 52, and then installs the upper tube 2 and the upper cover 1 on the top of the lower tube 4 in sequence, and then installs the first clamp 71, the second clamp 72 and the third clamp 73 in sequence to the outer periphery of the upper tube 2. The staff fastens the sliding device 7 to the upper tube 2 by rotating the first fastening bolt 74, and then installs the measuring device 8 to one side of the second clamp 72.

[0040] The staff can loosen or tighten the sliding device 7 by rotating the first fastening bolt 74, and manually move the sliding device 7 up and down to drive the straight plate 82 to adjust the horizontal height. After visually observing the elevation, lock the first fastening bolt 74, put the slide ruler 83 into the sliding hole, and one end of the slide ruler 83 falls to the bottom, and the horizontal height value can be checked. During the visual inspection, the horizontal height of the straight plate 82 can be fine-tuned by rotating the second fastening bolt 88. During the road construction process, the surveying device can stand on both sides of the road all the time, or multiple surveying devices can be set up along the road. After the construction is completed, the rope can be tied to the upper cover 1 and pulled out for disassembly. It can be recycled without loss and continued to be used later to avoid waste.
