Description

Technical Field

[0001] This utility model relates to the field of highway drainage technology, specifically a drainage structure for highway tunnels. Background Technology

[0002] During the construction of highway tunnels, it is necessary to bury circumferential drainage channels and longitudinal drainage channels within the tunnel walls. Generally, the circumferential drainage channels connect to the longitudinal drainage channels. Both the circumferential and longitudinal drainage channels are permeable structures, allowing the water behind the tunnel lining to be discharged from the outlet of the longitudinal drainage channel into the side trenches on both sides of the tunnel, thereby reducing the water pressure behind the lining structure.

[0003] However, existing highway tunnel drainage structures are prone to blockage by debris such as leaves during drainage, resulting in poor drainage performance.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a drainage structure for highway tunnels. Utility Model Content

The filter assembly 6 includes a filter ring 601, an adjustment hole 602, a baffle 603, a waterproof electric push rod 604, and a central shaft 605. The surface of the filter ring 601 has an adjustment hole 602, which collects and filters rainwater in the highway tunnel. The baffle 603 is installed inside the adjustment hole 602, which is used for installing the baffle 603 and providing space for its movement. A waterproof electric push rod 604 is installed on the side of the baffle 603. The filter ring 601 rotates at a constant speed with the central shaft 605. Adjacent baffles... 603 filters the garbage onto the surface of the filter ring 601, and the fixed end of the waterproof electric push rod 604 is connected to the central shaft 605. The filter ring 601 and the adjustment hole 602 are integrated structures, and the baffle 603 and the adjustment hole 602 are arranged in four sets in a ring about the center point of the filter ring 601. As the filter ring 601 rotates, the separating scraper 7 scrapes and cleans the garbage on the surface of the filter ring 601, thus achieving the function of automatic cleaning and ensuring the normal drainage of the highway tunnel. The top of the drainage box 1 is equipped with a collection plate 2. The arc-shaped collection plate 2 continues to collect rainwater from the highway tunnel, and a collection hole 3 is opened in the middle of the collection plate 2, which allows rainwater to enter the drainage box 1. A connecting pipe 4 is installed on the outside of the drainage box 1, and a connecting plate 5 is connected to the end of the connecting pipe 4.

[0023] like Figure 3 As shown, a slag collection chamber 8 is provided on the left side of the separating scraper 7. The slag collection chamber 8 plays a role in the unified collection of garbage. The slag collection chamber 8 is provided with an auxiliary component 9 for auxiliary cleaning. The auxiliary component 9 includes an auxiliary plate 901 and a connecting rod 902. The upper end of the auxiliary plate 901 is connected to the connecting rod 902. The length and width dimensions of the auxiliary plate 901 are consistent with the internal length and width dimensions of the slag collection chamber 8. The auxiliary plate 901 and the connecting rod 902 are fixedly connected. The auxiliary plate 901 is driven upward by the second waterproof electric push rod 904 to uniformly push the garbage in the slag collection chamber 8 outward, increasing the convenience of cleaning.

[0024] In summary, the drainage structure of this highway tunnel is first based on... Figures 1-3The structure shown involves installing the drainage box 1 in a pre-excavated trench in the highway tunnel, and then connecting the drainage pipe and the connecting plate 5. During use, rainwater from the highway tunnel falls through the collection holes 3 in the arc-shaped collection plate 2 onto the filter ring 601 in the drainage box 1, thus collecting and filtering the rainwater. Adjacent baffles 603 trap debris on the surface of the filter ring 601. Then, the central shaft 605 rotates at a constant speed driven by a motor. With the action of the filter ring 601, the separating scraper 7 scrapes the debris from the surface of the filter ring 601 into the slag collection chamber 8. The garbage cleaning function can achieve automatic cleaning and ensure normal drainage of highway tunnels. When the filter ring 601 rotates, the waterproof electric push rod 604 retracts, causing the baffle 603 to retract into the adjustment hole 602 so that the garbage on the surface of the filter ring 601 can be removed by the separating scraper 7. After the garbage is collected in the slag collection chamber 8, the waterproof electric push rod 904 extends, driving the auxiliary plate 901, the connecting rod 902 and the cover plate 903 to move upward. At this time, the upward movement of the auxiliary plate 901 plays a role in pushing the garbage in the slag collection chamber 8 outward, increasing the convenience of slag cleaning.
