Description

Technical Field

[0001] The utility model relates to the technical field of settlement monitoring, in particular to a settlement monitoring device for roadbed and pavement engineering construction. Background Art

[0002] Road settlement plates are engineering monitoring devices specifically used to monitor the settlement of roadbeds of transportation infrastructure such as roads and bridges. Their core function is to provide data support for engineering safety and quality control by measuring the vertical displacement changes of the roadbed. The settlement plates are mainly composed of a base plate and a measuring rod. Some are equipped with protective sleeves to prevent deformation of the measuring rod during filling.

[0003] Usually, settlement devices are installed along the edge of the road to facilitate subsequent measurement work. In order not to affect traffic and protect the leveling points, protective devices are used to protect the leveling points. As it rains, rainwater carries mud and sand into the protective mechanism, causing the top cover (leveling point) to be blocked by mud and sand. Surveyors need to clear the mud and sand before finding the leveling point, which reduces their work efficiency. For this reason, we propose a settlement monitoring device for roadbed and pavement construction. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The cone plate forms an inclined surface to guide rainwater and sediment into the annular V-shaped groove formed by the inner wall of the jacket and the bottom of the cone plate, and connects to the city sewer pipe through a connecting pipe, so that the sediment is brought into the sewer system during the flushing process of rainwater, thereby avoiding the need for surveyors to clean the leveling point during measurement, thereby improving measurement efficiency.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a technical solution: Figures 1-6 The settlement monitoring device for roadbed and pavement construction shown in the figure includes a sheath 1, a cone plate 2 for guiding water flow and sediment is fixedly connected to the bottom of the sheath 1, a connecting pipe 3 connected to the city sewer system is fixedly connected to one side of the cone plate 2, and a settlement monitoring component for settlement measurement is provided at the bottom of the cone plate 2. The settlement monitoring component includes a measuring tube 19, which is movably sleeved on the inner ring surface of the cone plate 2, and the top of the measuring tube 19 is connected to a top cover 20 for positioning through a thread, and the bottom of the measuring tube 19 is connected to an internal threaded sleeve 21 through a thread, and the bottom of the internal threaded sleeve 21 is fixedly connected to a base 22. When it rains, rainwater and sediment pass through the space between the clamping ring 4 and the movable cover plate 5. The gap enters the sleeve 1 and flows from the center to the surroundings along the inclined surface of the cone plate 2, and flows along the connecting port of the low connecting pipe 3 and the sleeve 1 to the sewer pipe on the side of the road, so that the silt in the sleeve 1 will not be washed away by rainwater and accumulated in the sleeve 1 during rainfall. When conducting regular settlement measurements, the surveyors open the movable cover plate 5 through the groove on the movable cover plate 5, so that the movable cover plate 5 overcomes the force of the tension spring 10 when opening, so that the movable cover plate 5 rotates around the hinge shaft 18 to open, until the ridge 15 is squeezed by deformation and clamped in the clamping groove 24, so that the movable cover plate 5 will not rebound due to the force of the tension spring 10, which is convenient for personnel to locate the position through the level.

[0024] like Figure 3 、 Figure 4 and Figure 6 As shown, the top of the sheath 1 is fixedly connected to a snap ring 4, the top of the snap ring 4 is coplanar with the ground surface, a movable groove 16 is provided on one side of the top of the snap ring 4, a hinge shaft 18 is fixedly connected to the inner wall on the side opposite to the movable groove 16, the side surface of the hinge shaft 18 is rotatably connected to a hinge plate 17, and one side of the hinge plate 17 is fixedly connected to a movable cover plate 5 for protecting the top cover 20.

[0025] like Figure 3 、 Figure 4 and Figure 6 As shown, a ridge 15 is fixedly connected to the arc surface of the hinge plate 17 , and a clamping groove 24 for clamping the ridge 15 is provided on the bottom inner wall of the movable groove 16 .

[0026] like Figure 3 、 Figure 4 and Figure 5 As shown, a first fixed shaft 8 is fixedly connected to the arc-shaped inner wall of the sheath 1, and a first shaft sleeve 6 is rotatably connected to the side surface of the first fixed shaft 8. A movable rod 7 is fixedly connected to the side surface of the first shaft sleeve 6. The other end of the movable rod 7 is fixedly connected to a baffle 9 for limiting the limit stroke of the movable rod 7. A tension spring 10 is fixedly connected to the other side of the baffle 9. The other end of the tension spring 10 is fixedly connected to a second shaft sleeve 12. The side surface of the second shaft sleeve 12 is fixedly connected to a movable tube 11. The tension spring 10 and the baffle 9 are both movably sleeved in the movable tube 11, and an inclined surface is formed by the cone plate 2 to guide rainwater and sediment to the annular V-groove formed by the inner wall of the sheath 1 and the bottom of the cone plate 2. The movable cover 5 is connected to the city sewer pipe through the connecting pipe 3, so that the silt is brought into the sewer system during the flushing process of rainwater, thereby avoiding the need for surveyors to clean the leveling point when measuring, thereby improving the measurement efficiency; through the card slot 24 and the ridge 15, the movable cover 5 will not reset after opening, avoiding the movable cover 5 blocking the top cover 20, thereby facilitating the positioning of the surveyors, and when the movable cover 5 is closed, the force of the tension spring 10 is used to make the movable cover 5 tightly closed in the clamping ring 4. When the rain is heavy, a large amount of rainwater seeps into the sheath 1, avoiding the exhaust effect to push the movable cover 5 open.

[0027] like Figure 2 、 Figure 3 and Figure 4 As shown, a second fixed shaft 13 is rotatably connected to the inner annular surface of the second shaft sleeve 12 , one end of the second fixed shaft 13 is fixedly connected to a connecting piece 14 , and the top of the connecting piece 14 is fixedly connected to the bottom of the movable cover plate 5 .

[0028] like Figure 3 、 Figure 4 and Figure 6As shown, the bottom edge of the movable cover plate 5 abuts against the limiting block 23 under the action of the tension spring 10 , and one side of the limiting block 23 is fixedly connected to the inner annular surface of the sheath 1 .

[0029] Working principle: When it rains, rainwater and mud enter the sleeve 1 through the gap between the retaining ring 4 and the movable cover plate 5, and flow from the center to the surrounding area along the inclined surface of the cone plate 2, and pass through the low connecting pipe 3 and the connection port of the sleeve 1, and flow along the connecting pipe 3 to the sewer pipe on the side of the road, so that the sleeve 1 will not be washed away by rainwater and silt will not accumulate in the sleeve 1. When personnel conduct regular settlement measurements, the movable cover plate 5 is opened through the groove on the movable cover plate 5, so that the movable cover plate 5 overcomes the force of the tension spring 10 when opening, so that the movable cover plate 5 rotates around the hinge shaft 18 to open, until the ridge 15 is squeezed by deformation and clamped in the clamping groove 24, so that the movable cover plate 5 will not rebound due to the force of the tension spring 10, which is convenient for personnel to locate the position through the level.
