[0006] Furthermore, the height of the handle when laid flat in the groove is not higher than the surface of the cover plate.

[0007] Furthermore, there are multiple connection holes.

[0008] The utility model can achieve the purpose of isolating the displacement observation pile from the surrounding pavement layer, and the displacement observation device is not covered by the pavement layer and can be used for observation at any time. The top surface of the protective cover is designed as an openable cover. After the cover is opened, it can be used for displacement observation. After closing, the cover and the box body can be locked by locking the connection hole or installing bolts, etc., to play a protective role. The top surface is painted with a color and pattern similar to the pavement layer so as not to affect the overall beauty of the track area.

[0009] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail below. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will be described in detail below in conjunction with the embodiments.

[0016] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0017] Figure 1 The figure is a top view of a tram track displacement observation pile protection cover provided by the utility model, which is particularly suitable for protecting urban tram track displacement observation piles. Figure 1 As shown, it includes a box body 1, a cover plate 2, a handle 3, a hinge 4, a fixing screw 5 and a connecting hole 6.

[0018] Figure 2 1 is a side cross-sectional view of a tram track displacement observation pile protective cover provided according to an embodiment of the utility model. Figure 1 and Figure 2As shown, a displacement observation scale 8 and a displacement observation pile 9 are set on the side of the tram track 7, the skirt at the bottom of the box body 1 is fixed to the ground on the side of the tram track 7 by fixing screws 5, and the box body 1 covers the position above the displacement observation scale 8 and the displacement observation pile 9.

[0019] Specifically, one side of the cover plate 2 is connected to the box body 1 through a hinge 4 , a groove 10 is provided on the cover plate 2 , the handle 3 is installed in the groove 10 , and connecting holes 6 are provided at corresponding positions on both sides of the cover plate 2 and the top of the box body 1 .

[0020] Preferably, the height of the handle 3 when laid flat in the groove 10 is not higher than the surface of the cover plate 2 .

[0021] According to the requirements of technical specifications, the seamless line tracks need to be regularly observed for displacement. After the urban tram seamless line displacement observation piles are covered by the pavement layer, they cannot be observed normally and are easily damaged.

[0022] The utility model can isolate the displacement observation pile from the surrounding pavement layer, and the displacement observation device is not covered by the pavement layer and can be used for observation at any time. The top surface of the protective cover is designed as an openable cover. Specifically, the cover plate 2 can be opened by no less than 180 degrees, and when the cover plate 2 is closed, it can be locked with the box body 1 through the connecting hole 6. The number of the connecting holes 6 is multiple.

[0023] After the cover plate 2 is opened, displacement observation can be performed. After closing, the cover plate 2 and the box body 1 can be locked by locking or installing bolts in the connection holes 6 to play a protective role. The top surface is painted with a color and pattern similar to the pavement layer so as not to affect the overall appearance of the track area.

[0024] When making the protective cover, the box and cover can be made of glass fiber reinforced plastic or other materials that are strong enough to resist the pressure of the external pavement layer and can be easily shaped according to the track structure. During installation, the track displacement observation pile is covered in it, and the bottom of the protective cover is firmly fixed to the integral track bed with fixing screws. After the cover is closed and firmly connected to the box, the tram pavement layer can be constructed. When it is necessary to observe the track displacement, the cover can be opened to carry out the displacement observation operation. After completion, the cover is covered again and locked, and the handle is placed flat in the groove of the cover.

[0025] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
