[0002] During the construction of the spillway dam, it is necessary to conduct safety monitoring of the dam body, and to guide the construction of the spillway dam through the monitoring data obtained to ensure the stability and safety of the dam during construction and use. The safety monitoring of the spillway dam is carried out by monitoring instruments, and the cables of the monitoring instruments need to be buried in the concrete of the spillway dam. After the cables of the monitoring instruments are buried in the concrete of the spillway dam, it is difficult to repair and replace them. During the construction of the spillway dam, the cables of the monitoring instruments buried inside the spillway dam need to go through one or more flood seasons. How to effectively protect the cables of the monitoring instruments and ensure the normal operation of the monitoring instruments is crucial to obtaining monitoring data during the construction of the spillway dam and guiding the construction of the spillway dam.

[0003] In the process of protecting the cables of monitoring instruments, the existing protection method is to set concrete slag and waterproof geotextile at the collection position of the cables, wrap the waterproof geotextile with the cables, and then cover the concrete slag on the waterproof geotextile. This method has the following problems: the surface of the concrete slag is relatively sharp, and when the concrete slag is too thick or too heavy, it is easy to crush the cables; during the flood season, the cables are under the impact of water flow for a long time, and the concrete slag and waterproof geotextile are easily washed away by the water flow. The cables are exposed and soaked in water, and are easily punctured by hard objects in the water flow, resulting in damage, breakage, water ingress, etc. to the cables, making it impossible to obtain monitoring data, affecting the accuracy of later monitoring data collection, and affecting the assessment of the safety status of the flood discharge dam.

[0027] When the flood season comes, the cables of the adjacent dam sections are planned and concentrated according to the designed routing method. After the box 1 covers the cables, the box 1 is installed on the flood discharge dam 4 through the connecting structure 3 ( Figure 2 Only part of the structure of the flood discharge dam is shown in the figure), which can ensure the stability of the box 1 on the flood discharge dam 4. Under the action of the box 1, the water flow will not impact the cable, thereby effectively preventing the cable from being damaged and ensuring the reliability of the subsequent monitoring data; under the action of the cover plate 2, it can prevent the mud and hard objects in the water flow from entering the box 1. After the flood season, the cleaning of the mud in the box 1 can be avoided, thereby improving the construction efficiency of subsequent operations.

[0028] The box body 1 includes two first side panels 11 and two second side panels 12, both ends of the first side panels 11 are respectively connected to the second side panels 12 (welded or integrally formed), and the cover plate 2 is detachably arranged on the top of the box body 1. After the box body 1 covers the cables, the state of the cables in the box body 1 can be arranged through the opening on the top of the box body 1, so that the box body 1 completely covers the cables. The cover plate 2 can be directly inserted and covered on the top of the box body 1, or the box body 1 can be hinged.

[0029] The first side plate 11 and the second side plate 12 are both made of steel plates with a thickness of not less than 2 mm. The steel plates have strength, toughness and corrosion resistance, which can enhance the corrosion resistance of the box body 1 in water and enhance the deformation resistance of the box body 1.

[0030] refer to Figure 1 , angle steels 5 are provided at the top and bottom of the box body 1, and the angle steels 5 are respectively connected to the top and bottom of the first side panel 11 and the top and bottom of the second side panel 12 to hem the top and bottom of the box body 1 and enhance the overall structural strength of the box body 1. When the first side panel 11 is welded to the second side panel 12, angle steels are also provided at the connection position between the first side panel 11 and the second side panel 12. Providing angle steels at the connection position between the first side panel 11 and the second side panel 12 can improve the anti-deformation ability of the box body 1 and prevent the box body 1 from deforming under the impact of water flow. One end of the cover plate 2 is hinged to one of the first side panels 11 or the second side panel 12 of the box body 1 through a hinge 6.

[0031] refer to Figure 3The bottom of one of the first side panels 11 of the box 1 is provided with a wire conduit opening 7 for passing the cable; the wire conduit opening 7 can prevent interference between the cable and the box 1. When the box 1 covers the cable, the bottom of the second side panel 12 of the box 1 can be in good contact with the top surface of the flood discharge dam, and the wire conduit opening 7 can prevent the bottom of the box 1 from pressing the cable and causing damage to the cable. The cable is also wrapped with a waterproof geotextile (not shown in the figure). When water enters the box 1 from the gap of the box 1, the waterproof geotextile can prevent the cable from being soaked by water, ensuring the reliability of the subsequent work of the cable.

[0032] refer to Figure 2 , the main steel bar 8 of the flood discharge dam 4 extends out of the top of the flood discharge dam 4, and the box body 1 is connected to the main steel bar 8. During the connection between the box body 1 and the main steel bar 8, when the cover plate 2 is directly covered on the top of the box body 1, any side plate of the box body 1 can be welded to the main steel bar 8, and the connection structure 3 includes a first connection member 31, a first end of the first connection member 31 is welded to the cover plate 2, and a second end of the first connection member 31 is welded to the main steel bar 8; the first connection member 31 is used to stably cover the cover plate 2 on the box body 1, to ensure the stability of the cover plate 2 in the water flow, thereby effectively preventing mud and hard objects in the water from entering the box body 1. When the cover plate 2 is hinged to one of the first side panels 11 of the box body 1 through the hinge 6, the wire pipe opening is preferably arranged at the bottom of the other first side panel 11 opposite to the first side panel 11. When connecting the box body 1, the first side panel 11 of the box body 1 provided with the wire pipe opening 7 is welded to the main steel bar 8. Similarly, the first end of the first connecting member 31 is welded to the cover plate 2, and the second end of the first connecting member 31 is welded to the main steel bar 8.

[0033] The connection structure 3 also includes a second connection member 32, a first end of the second connection member 32 is welded to the first side plate 11 or the second side plate 12 of the box body 1, and a second end of the second connection member 32 is welded to the main steel bar 8. The second connection member 32 is used to improve the stability of the connection between the box body 1 and the main steel bar 8 to prevent the box body 1 from being washed away by the water flow. The second connection member 32 can also prevent the side plate of the box body 1 from being directly welded to the main steel bar 8, and when the box body 1 is dismantled later, the damage to the side plate of the box body 1 can be reduced.

[0034] The first connecting member 31 and the second connecting member 32 can both be made of steel bars (with a diameter of 22-28 mm) or screws; when the first connecting member 31 and the main steel bar 8, and the second connecting member 32 and the main steel bar 8 are connected by welding, after the flood season, the connection position between the first connecting member 31 and the main steel bar 8 and the connection position between the second connecting member 32 and the main steel bar 8 can be knocked off respectively, so as to remove the box 1 and allow the cables covered by the box 1 to be used normally.

[0035] When the connection structure 3 includes a first connection member 31 and a second connection member 32, the installation method of the box body 1 includes: after the cables of adjacent dam sections are planned and concentrated according to the designed routing method, the wire pipe opening 7 of the box body 1 clamps the cable pipe so that the box body 1 covers the cable, and the first side plate 11 of the box body 1 is close to or in contact with the main steel bar 8, and the bottom of the box body 1 is in contact with the top surface of the flood discharge dam; after observing and adjusting the cable state from the top of the box body 1, the cover plate 2 is closed, and then the cover plate 2 is connected to the main steel bar 8 by using the first connection member 31, and the second side plate 12 is connected to the main steel bar 8 by using the second connection member 32. The second connection member 32 can be set only on the second side plate 12 on the back water flow side of the box body 1, or it can be set on the water flow side and the second side plate 12 on the back water flow side of the box body. After connection, the first side plate 11 can also be welded to the main steel bar 8 to further improve the stability of the connection between the box body 1 and the main steel bar 8.

[0036] refer to Figure 4~Figure 6 The connection structure also includes a third connection member 33, which is detachably connected to the main steel bar 8. Under the action of the third connection member 33, damage to the box body 1 structure and the main steel bar 8 can be avoided during the removal of the box body 1, thereby increasing the number of turnovers of the box body 1 and ensuring the structural strength of the flood discharge dam 4. The third connection member 33 is a steel plate, and one or more first slide grooves 331 are arranged upward along the length of the third connection member 33 (refer to Figure 5 ), each first slide groove 331 is arranged along the height direction of the third connecting member 33; one or more second slide grooves 332 are respectively arranged near the left and right ends of the third connecting member 33, and each second slide groove 332 is arranged along the length direction of the third connecting member 33; correspondingly, one or more connecting tubes 9 are arranged in the height direction of the second side plate 12 of the box body 1, and one or more connecting tubes 9 are arranged in the length direction of the second end of the cover plate 2. The connecting tube 9 is welded to the second side plate 12 and the connecting tube 9 is welded to the cover plate 2. An internal thread is axially arranged on the connecting tube 9, so that the first connecting member 31 passes through the first slide groove 331 to be connected to the cover plate 2, and the second connecting member 32 passes through the second slide groove 332 to be connected to the second side plate 12 of the box body 1. Nuts are arranged on the first connecting member 31 and the second connecting member 32, and the box body 1 and the third connecting member 33 can be fastened together by rotating the nuts.

[0037] The third connector 33 is also provided with a connecting buckle 10, which is welded or detachably connected to the third connector 33. The connecting buckle 10 is used to make the third connector 33 detachably arranged on the main steel bar 8, so as to facilitate the later removal of the box body 1. The connecting buckle 10 is a cylindrical structure, and its inner diameter is adapted to the diameter of the main steel bar 8, so that the connecting buckle 10 can be sleeved on the main steel bar 8. A notch is provided on the connecting buckle 10, and connecting plates are respectively provided at both ends of the notch. The two connecting plates are connected by adjusting screws. By adjusting the adjusting screws, the distance between the two connecting plates can be reduced, so that the connecting buckle 10 is fastened to the main steel bar 8, so that the box body 1 and the main steel bar 8 are stably connected. A rubber ring is also provided in the connecting buckle 10. When the distance between the two connecting plates of the connecting buckle 10 is reduced, the rubber ring can be squeezed, thereby enhancing the stability of the connection between the connecting buckle 10 and the main steel bar 8.
