Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal road drainage devices, in particular to a drainage ditch for municipal road drainage. Background Art
[0002] Municipal roads, as the arteries of urban transportation, have multiple important functions. First, drains effectively collect and drain rainwater, reducing road waterlogging and ensuring driving safety and pedestrian access. Drains are particularly effective during the rainy season or heavy rainstorms, quickly channeling rainwater into the underground drainage system, preventing waterlogging and traffic congestion. Second, drains help protect road structures. Long-term waterlogging can damage the road base, leading to pavement damage and increasing maintenance costs. Drains reduce water erosion and extend road life. Furthermore, drains serve as sewage disposal systems. In cities, domestic and industrial wastewater must be treated through drainage systems. As part of this system, drains ensure that wastewater is effectively collected and transported to sewage treatment plants, reducing environmental pollution. In urban planning, drainage design also takes ecological and aesthetic considerations into account. Modern drainage systems are often integrated with green belts, which not only beautify the urban environment but also enhance the infiltration and absorption of rainwater, contributing to sustainable urban development. However, traditional drainage ditches are close to green belts, so leaves or other debris will fall on the drainage ditches and accumulate on the drainage ditches. On rainy days, this will greatly affect the drainage function of the drainage ditches, resulting in low drainage efficiency of the drainage ditches and causing a large amount of water to accumulate on the road surface. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the utility model provides a drainage ditch for municipal road drainage, which solves the problem of low drainage efficiency of traditional drainage ditches due to accumulation of leaves or debris under heavy rain or rainstorm conditions.
[0004] In order to achieve the above-mentioned purpose, the utility model provides a drainage ditch for municipal road drainage, including a cover plate for installation at the water inlet of an external drainage pipe, the cover plate is penetrated by a through groove, a drainage block is provided at the center point of the through groove, the two side walls of the drainage block are respectively connected to the inner walls on both sides of the through groove, the two ends of the drainage block are respectively matched with the gap between the inner walls at both ends of the through groove and form a drainage gap for external water flow to be poured into the water inlet of the external drainage pipe, and the drainage block is provided with a drainage structure for guiding the movement direction of external leaves or debris and causing them to move to the drainage gap through the guidance of the external water flow.
[0005] The benefit of adopting the above technical solution is that: when leaves or other debris fall on the cover plate, due to the setting of the drainage gap, a small number of leaves or debris will fall directly into the external drainage pipe through the drainage gap, but some leaves will still fall on the drainage block. However, the setting of the drainage structure allows a small number of leaves or debris to fall into the drainage gap along the top wall of the drainage block. At the same time, under rainy conditions, the drainage structure will cooperate with the water flow formed by rainwater to flush the leaves or debris to the drainage gap through the water flow, so that the leaves or debris can be discharged into the drainage pipe through the drainage gap, thereby achieving the flushing of leaves and debris, and avoiding excessive accumulation of leaves or debris resulting in low drainage efficiency.
[0006] The utility model is further provided with: the radial cross section of the top wall of the drainage block is arranged in an arc shape, and the highest point of the arc is arranged at the center of the top wall of the drainage block.
[0007] The benefits of adopting the above technical solution are: in the above technology, the radial cross-section of the top wall of the drainage block is arranged in an arc shape and the highest point of the arc is arranged at the center of the top wall of the drainage block, so that when leaves or debris fall on the drainage block, some leaves or debris will slide along the top wall of the drainage block until they enter the drainage gap, thereby improving the leaf discharge efficiency. At the same time, under rainy conditions, rainwater will fall on the top wall of the drainage block and flow into the drainage gap along the arc direction of the top wall of the drainage block, thereby improving the rainwater discharge efficiency. At the same time, when rainwater flows, it will drive the leaves to move, and then the leaves will move into the drainage gap, avoiding excessive accumulation of leaves or debris resulting in low drainage efficiency.
[0008] The utility model is further provided with: the drainage structure includes a first water storage tank provided on the top wall of the drainage block, both sides of the first water storage tank are connected with a plurality of water diversion tanks, and the plurality of water diversion tanks are connected to the end of the drainage block.
[0009] The benefits of adopting the above technical solution are: the first water storage tank in the above technology is used to accumulate rainwater, and at the same time, a number of water diversion tanks are connected on both sides of the first water storage tank, so that the accumulated rainwater will flow into the drainage gap along the water diversion tank, thereby improving the drainage efficiency. At the same time, the accumulated rainwater will wash away the leaves accumulated on the top wall of the drainage block when flowing through the water diversion tank, thereby driving the leaves to move and move them into the drainage gap; the setting of the above technology in ordinary countries improves the rainwater discharge efficiency and avoids excessive accumulation of leaves or debris resulting in low drainage efficiency.
[0010] The utility model is further provided with: the drainage structure also includes a plurality of drainage strips, the plurality of drainage strips are divided into two groups and are arranged at both ends of the drainage block, the gaps between adjacent drainage strips are matched to form a water flow groove, each of the water flow grooves is connected to the adjacent drainage gap, and the drainage strips and the drainage block are arranged relatively inclined.
[0011] The benefits of adopting the above technical solution are: the setting of several drainage strips in the above technology prevents leaves from excessively stagnating at both ends of the drainage block, that is, when the leaves are guided by rainwater and move to the two ends of the drainage block, some leaves will pass through the gutter directly into the drainage gap, thereby improving the leaf discharge efficiency, but some leaves will still stagnate between the two drainage strips, that is, cover the top of the gutter, and under the erosion of rainwater, a part of the water flow will first accumulate on the leaves, but the leaves are located between the two drainage strips, that is, the two ends of the leaves are supported by the drainage strips and the middle end is in a suspended state. When the water flow accumulates to a first certain level, the accumulated water flow will drive the leaves into the gutter under the downward pressure of gravity, and then directly into the drainage gap through the gutter, thereby achieving the purpose of leaf discharge. At the same time, the drainage strip and the drainage block are relatively inclined to improve the efficiency of leaf falling and avoid the phenomenon of leaves stagnating at the drainage strip; the setting of the above technology improves the efficiency of rainwater discharge and avoids excessive accumulation of leaves or debris leading to low drainage efficiency.
[0012] The utility model is further configured that: the positions of the plurality of water diversion grooves are arranged in a one-to-one correspondence with the positions of the plurality of drainage strips.
[0013] The benefit of adopting the above technical solution is that: in the above technology, several water diversion trough positions are set in one-to-one correspondence with several drainage bar positions, so that the accumulated water in the first water storage tank flows along the water diversion trough and flows to the drainage bar position, thereby allowing the stagnant leaves on the drainage bar to be washed away, thereby improving the flushing and drainage efficiency.
[0014] The present invention is further provided with: the drainage structure also includes a second water storage tank annularly opened on the outer edge of the cover plate, and the second water storage tank is connected to the first water storage tank.
[0015] The benefit of adopting the above technical solution is that: by setting up the second water storage tank, water flow can be accumulated in advance and the accumulated rainwater can be discharged into the first water storage tank, thereby improving the fluidity and flow pressure of the water flow in the first water storage tank, and the water flow can discharge the leaves more quickly during discharge.
