Description

Technical Field

[0001] This utility model relates to the field of road drainage technology, specifically to road drainage devices for civil engineering. Background Technology

[0002] In the field of civil engineering, road drainage systems are critical infrastructure for ensuring the durability, safety, and comfort of roads. Traditional road drainage systems typically employ a combination of fixed storm drain grates and underground drainage pipes, using gravity to collect surface water into the municipal pipe network.

[0003] However, in extreme weather, rainwater carrying fallen leaves and garbage can easily clog the inlets of storm drain grates, limiting their drainage capacity and causing them to succumb to the intensity of rainfall. This can lead to road flooding or even waterlogging. Currently, to prevent flooding, road workers simply remove the storm drain grates. While this significantly increases drainage efficiency, fallen leaves and garbage can directly enter the drainage pipes, causing blockages and making cleaning the pipes difficult after extreme weather events. Summary of the Invention

[0004] The purpose of this invention is to provide a road drainage device for civil engineering projects to solve the problems mentioned in the background art.

[0022] Preferably, the jacking mechanism includes:

[0023] A lead screw, the bottom of which is rotatably inserted into the bottom of a drainage pipe via a bearing;

[0024] A slider, wherein the slider is threadedly inserted into the outer helical groove of the lead screw;

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1

[0041] Please see Figure 1-3This utility model provides a technical solution: a drainage device for civil engineering roads, comprising a drainage pipe 1, an inlet 2, a rain grate 3, a leaf collection mechanism 4, and a jacking mechanism 5. The inlet 2 is located at the top of the drainage pipe 1, allowing rainwater to enter the inner cavity of the drainage pipe 1 through the inlet 2. The rain grate 3 is installed at the top of the inner cavity of the inlet 2, and is used to prevent fallen leaves and other objects from entering the inner cavity of the drainage pipe 1 under normal conditions, without affecting rainwater entering the inner cavity of the drainage pipe 1 through the rain grate 3 during non-extreme weather. The leaf collection mechanism 4 is installed below the rain grate 3. Structure 4 is used for filtering fallen leaves and garbage. The fallen leaf collection mechanism 4 is used to collect and filter fallen leaves and other debris by rainwater entering the inner cavity of the drainage pipe 1 from the periphery of the inlet 2 under extreme weather conditions. The jacking mechanism 5 is installed in the middle of the fallen leaf collection mechanism 4. The jacking mechanism 5 is used to lift the rain grate 3 so that in extreme weather conditions, if the rainwater is too heavy and the fallen leaves block the water inlet holes on the rain grate 3, or if the drainage is too light, the jacking mechanism 5 will lift the rain grate 3 so that rainwater and floodwater can enter through the rain grate 3 and the periphery of the inlet 2, thereby speeding up the drainage and preventing flooding.

[0042] The rain grate 3 includes a grate body 31, a barrier net 32, reinforcing steel bars 33, and a connecting cover 34. The grate body 31 is located inside the inlet 2 to prevent debris such as fallen leaves from entering the drainage pipe 1, ensuring the stability of the road. The barrier net 32 ​​is installed in the middle of the grate body 31 to prevent pedestrians and objects from falling into the drainage pipe 1. Multiple reinforcing steel bars 33 are fixed at equal intervals at the bottom of the grate body 31. The connecting cover 34 is movably engaged in the middle of the grate body 31. A connecting hole is opened in the middle of the grate body 31, and the connecting cover 34 is engaged in the top of the connecting hole to protect the inner cavity of the connecting hole. The connecting hole also facilitates the convenient rotation of the jacking mechanism 5.

[0043] In addition, the leaf collection mechanism 4 includes positioning steel bars 41, fixing rings 42, a net 43, and a support block 44. Multiple positioning steel bars 41 are fixed to the inner wall of the inlet 2 in a rectangular array. One end of each positioning steel bar 41 has a curved structure. The fixing ring 42 is fixed to one end of each positioning steel bar 41. The shape of the fixing ring 42 is not limited; it can be a rectangular or circular ring structure. This facilitates protection of the inner cavity of the inlet 2 and reduces the risk of children falling in. The net 43 is fixed to two adjacent positioning steel bars 41. Between 1 and 2, the net bag 43 is used to filter garbage and fallen leaves, which helps to reduce the risk of impurities in the rainwater entering from the periphery of the rain grate 3 and the inlet 2 causing blockage of the drainage pipe 1. At the same time, cleaning personnel can clean the impurities in the inner cavity of the net bag 43 by reaching into the gap between the rain grate 3 and the inlet 2, which improves the convenience of cleaning impurities such as fallen leaves. The support block 44 is fixed to the middle of the fixing ring 42 by multiple support rods. The support block 44 is used to improve the stability of the position of the jacking mechanism 5.

[0044] Furthermore, the jacking mechanism 5 includes a lead screw 51, a slider 52, a rotating block 53, a rubber telescopic sleeve 54, and a bracket 55. The bottom of the lead screw 51 is rotatably inserted into the bottom of the drainage pipe 1 via a bearing. The lead screw 51 is rotatably inserted into the middle of the bearing block 44 via a bearing. The top of the lead screw 51 has an external helical groove structure. The slider 52 is threaded into the external helical groove of the lead screw 51. The rotating block 53 is fixed to the top of the lead screw 51. The rubber telescopic sleeve 54 is sleeved on the top of the lead screw 51 and is used for the external helical groove of the lead screw 51. For protection, the rubber telescopic sleeve 54 is fixed between the slider 52 and the rotating block 53, and multiple brackets 55 are fixedly installed between the slider 52 and the reinforcing steel bar 33. By removing the connecting cover 34 and reaching into the connecting hole, the operator can rotate the rotating block 53, causing the slider 52 to drive the brackets 55 to rise, compressing the rubber telescopic sleeve 54. This allows the rain grate 3 to be pushed out of the inner cavity of the inlet 2, facilitating rainwater drainage from the periphery of the inlet 2, increasing drainage capacity, and making it suitable for rainwater drainage in extreme weather conditions, reducing the occurrence of floods.

[0045] Example 2

[0046] Based on Example 1, such as Figure 2 As shown, the civil engineering road drainage device also includes a sediment collection mechanism 6. The sediment collection mechanism 6 is set on both sides of the inner cavity of the drainage pipe 1. The sediment collection mechanism 6 includes a bearing groove 61, a stepped groove 62, and a barrier bar 63. The bearing groove 61 is set on both sides of the bottom of the screw 51 and is opened at the bottom of the drainage pipe 1. The stepped groove 62 is opened on the inner wall of the bearing groove 61 away from the screw 51. Multiple barrier bars 63 are fixed at equal intervals to the inner wall of the drainage pipe 1. The barrier bars 63 are used to block animals. The stepped groove 62 is set to prevent sediment from being washed out by the water flow in large quantities, reduce the blockage of the inner cavity of the drainage pipe 1 by sediment, and improve the smoothness of drainage.
