Detailed Description
The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses a construction method of an electric power tunnel. Referring to fig. 1, electric power tunnel includes tunnel body 1, and water drainage tank 11 has been seted up to tunnel body 1's bottom, and water drainage tank 11's bottom intercommunication has connecting pipe 21, and connecting pipe 21 keeps away from the fixed and intercommunication of water drainage tank 11's one end and has header tank 2, and header tank 2 is located tunnel body 1's below and pre-buried underground. The upper end opening part joint of water drainage tank 11 has filter 12, is connected with the actuating mechanism 3 that drives the lift of filter 12 on filter 12.
A mounting pipe 22 is fixed on one side wall of the water collecting tank 2 and communicated with the water collecting tank, and one end of the mounting pipe 22, far away from the water collecting tank 2, extends out of the ground and is connected with a water suction pump 23.
When water is accumulated in the tunnel body 1, the accumulated water in the tunnel body 1 enters the water collecting tank 2 along the drainage groove 11 and the connecting pipe 21, and the accumulated water is collected in the water collecting tank 2; when meetting heavy rain weather and probably leading to the inside ponding of tunnel body 1 when more, thereby start actuating mechanism 3 and drive filter 12 and rise and break away from water drainage tank 11, the inside ponding of tunnel body 1 this moment can be quick pass water drainage tank 11, in connecting pipe 21 gets into header tank 2, start suction pump 23 simultaneously and make the inside water of header tank 2 along installation pipe 22 discharge header tank 2, so can guarantee the quick discharge of the inside ponding of tunnel body 1.
Actuating mechanism 3 includes lead screw 31 and driving motor 32, and the vertical direction setting of lead screw 31 is inside tunnel body 1, and in the lower extreme of lead screw 31 and filter 12 threaded connection stretched into water drainage tank 11, the upper end of lead screw 31 rotated with tunnel body 1's top surface and is connected, and the upper end of lead screw 31 runs through tunnel body 1 and stretches out ground fixedly connected with driving motor 32's output shaft. The drive motor 32 has a forward and reverse rotation.
When the driving motor 32 is started to drive the screw rod 31 to rotate, the screw rod rotates to drive the filter plates 12 to move towards or away from the drainage groove 11. When the filter plate 12 is clamped with the drainage groove 11, the filter plate 12 is difficult to continue to move towards the direction close to the drainage groove 11, i.e. the filter plate 12 is not easy to separate from the screw rod 31. The lead screw 31 is generally referred to as a ball screw 31 so that the filter plate 12 can be lifted without being guided.
Referring to fig. 1 and 2, a plurality of support plates 4 arranged in the vertical direction are screwed on the screw rod 31, preferably three support plates 4 in the embodiment, and the support plates 4 are used for placing and supporting cables inside the tunnel body 1. And two ends of each supporting plate 4 are respectively connected with a sliding frame 5 in a sliding mode, and the sliding frames 5 can also provide support for the cables. The carriage 5 is movable relative to the support plate 4 in a direction away from the support plate 4 or closer to the support plate 4. Every carriage 5 keeps away from the equal fixedly connected with sliding block 521 of one end of backup pad 4, all sets up the sliding tray 13 of vertical setting on the both sides wall of tunnel body 1, and every sliding block 521 all with corresponding sliding tray 13 sliding connection.
When the lead screw 31 rotates to drive the filter plate 12 to ascend, the accumulated water in the tunnel body 1 is more and the possibility of increasing the accumulated water continuously is realized, and the lead screw 31 rotates to drive the support plate 4 to ascend so that the cable on the support plate 4 is far away from the bottom surface of the tunnel body 1, so that the possibility that the cable on the support plate 4 contacts the accumulated water is reduced.
Simultaneously backup pad 4 rises and makes carriage 5 slide to the direction of keeping away from backup pad 4 to sliding block 521 slides along sliding tray 13 simultaneously, thereby can make backup pad 4 smooth drive carriage 5 rise, so also can reduce the possibility of the cable contact ponding on the carriage 5, the better cable on protection backup pad 4, the carriage 5.
Strip-shaped groove 41 has been seted up respectively to the both sides wall of backup pad 4, and carriage 5 is including being located the connecting rod 51 of backup pad 4 both sides respectively, still including being located two connecting rods 51 and keeping away from the annular rod 52 between the one end of bracing piece, and one side and sliding block 521 fixed connection of backup pad 4 are kept away from to annular rod 52, and one side that every connecting rod 51 is close to strip-shaped groove 41 is fixed with respectively and is connected connecting block 511 with strip-shaped groove 41 sliding connection.
When the support plate 4 is lifted, the connection block 511 slides in the bar-shaped groove 41, thereby driving the sliding frame 5 to move toward or away from the support plate 4. The annular rod 52 can reduce the possibility that the sliding frame 5 collides with the side wall of the tunnel body 1 in the lifting process of the sliding frame 5, so that the sliding frame 5 can be smoothly lifted.
Referring to fig. 1 and 3, the installation pipe 22 includes a first pipe 221 connected to the water collection tank 2, and further includes a second pipe 222 located above the first pipe 221, a transition sphere 223 having a hollow structure is connected between the first pipe 221 and the second pipe 222, and the transition sphere 223 is respectively communicated with the first pipe 221 and the second pipe 222. The diameter of the transition sphere 223 is greater than the diameter of the first tube 221, and the diameter of the transition sphere 223 is greater than the diameter of the second tube 222. The middle part of the transition sphere 223 is fixedly connected with a separation net 6 arranged in the horizontal direction, and the separation net 6 divides the transition sphere 223 into an upper part and a lower part.
The floating ball 7 is arranged inside the separating ball body, and the floating ball 7 is located at one side of the separating plate close to the first pipe body 221 and abuts against the joint of the transition ball body 223 and the first pipe body 221. The side wall of the floating ball 7 is fixedly connected with a connecting wire 8 made of rigid material, the top wall of the part of the second pipe body 222 exposed out of the ground is provided with a connecting hole 224, and the connecting wire 8 penetrates through the separation net 6 and vertically upwards penetrates through the connecting hole 224. Connecting wire 8 is including arranging sign section 82 inside connecting hole 224 in and arranging the outside spacing ball 81 of second body 222 in, and the material of spacing ball 81 is lighter, and sign section 82 adopts the bright-colored pigment of colour to paint, and sign section 82 paints red pigment in this embodiment.
When the inside water of header tank 2 is more when water gets into transition spheroid 223 along first body 221 inside, float ball 7 upwards showy under the effect of water buoyancy, so float ball 7 and drive connecting wire 8 and rise, observe when sign section 82 stretches out connecting hole 224 when the staff, start suction pump 23 and draw water and start driving motor 32 simultaneously, float ball 7 this moment and break away from the junction of transition spheroid 223 with first body 221, the suction pump 23 of being convenient for is normally drawn water. The separation net 6 restricts the floating ball 7 from floating upward to block the junction of the transition ball 223 and the second tube 222.
One end fixedly connected with installation ball 83 that spacing ball 81 was kept away from to sign section 82, when sign section 82 stretches out connecting hole 224, thereby installation ball 83 contradicts the inner wall of second body 222 and makes installation ball 83 block up connecting hole 224, and the suction pump can draw water better like this.
Referring to fig. 1, the position of the transition sphere 223 is not lower than the lowest support plate 4 connected with the screw rod 31, so that when the accumulated water in the tunnel body 1 does not submerge the lowest support plate 4, a worker can timely accumulate the water in the tunnel body 1 and start the water suction pump 23 and the driving motor 32.
