Description

Technical Field

[0001] The utility model relates to the technical field of drainage, in particular to a road plate which is conducive to draining water from a basement well. Background Art

[0002] With the increasing number of vehicles, the usable area on the ground can no longer meet people's needs. Underground garages are indispensable buildings in modern society. The entrance to the underground garage is usually an open ramp. In rainy weather, rainwater will flow into the basement along the ramp. If it cannot be discharged in time, it will cause waterlogging, resulting in huge economic losses. The existing treatment method usually sets up a shade well at the junction of the ramp and the parking layer to drain rainwater and prevent waterlogging. The manhole cover of the shade well is usually straight-through, and some rainwater can easily flow into the basement along the ungrooved part of the manhole cover. The drainage efficiency is not high, and it will also affect the underground garage. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the drainage manhole cover of the existing underground garage adopts a straight-through method, and the drainage efficiency is not high. Part of the rainwater will flow into the basement along the upper surface of the manhole cover, affecting the normal use of the basement. In view of the above problem, a road plate which is conducive to the drainage of the underground manhole is proposed, including a manhole cover frame, a plurality of vertical rods and a reinforced support rod. The vertical rods are divided into two groups and are evenly staggered with each other in sequence, and are respectively connected to the inner wall of the upper side or the lower side of the manhole cover frame. The length of the vertical rod is less than the distance between the upper and lower sides of the manhole cover frame. The side of the vertical rod away from the connecting end is an inclined portion, and the inclined portion is inclined downward. The reinforced support rod is arranged below the manhole cover frame, and the reinforced support rod is in contact with the lower surface of the vertical rod and is connected to the two side edges of the manhole cover frame through a connecting piece.

[0004] The technical solution of the utility model is that one end of the vertical rod is connected to the inner wall of the manhole cover frame, and the other end is inclined downward to have a certain distance from the inner wall on the other side, so as to increase the drainage efficiency and reduce the probability of rainwater flowing into the underground parking layer along the upper surface of the vertical rod; by setting the structure of the reinforced support rod, the support is strengthened under the vertical rod to improve the strength, so as to avoid the vertical rod breaking when a vehicle passes by, which will cause damage to the vehicle.

[0005] Preferably, the lower surfaces of both side edges of the manhole cover frame are provided with first slots for engaging the reinforcing support rods, and the first slots facilitate positioning of the reinforcing support rods and fixation thereof through connecting pieces.

[0006] Preferably, the lower surface of the vertical rod is provided with a second slot for engaging the reinforcing support rod. After the reinforcing support rod is fixed, the vertical rod engages the reinforcing support rod through the second slot to prevent the vertical rod from shaking.

[0007] Preferably, the connecting piece is a hexagonal bolt, by which the manhole cover frame and the reinforcing support rod are fixed, and the reliability is high.

[0008] Preferably, the lower surface of the reinforcing support rod is provided with a countersunk hole for passing the hexagonal bolt. The hexagonal bolt is embedded in the countersunk hole after being fixed. By sealing and blocking the countersunk hole, the problem of rust of the hexagonal bolt caused by water seepage can be prevented.

[0009] Preferably, a limit block is provided on the upper surface of the reinforced support rod, and the limit block is located between two adjacent vertical rods. The two adjacent limit blocks cooperate with each other to clamp the vertical rod, thereby further reducing the probability of shaking.

[0010] Preferably, the cross section of the limit block is in the shape of a semicircular arc, and the arc has a guiding effect on rainwater, so that it can fall smoothly into the well.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The technical solution of the utility model is that one end of the vertical rod is connected to the inner wall of the manhole cover frame, and the other end is inclined downward and has a certain distance from the inner wall on the other side. This can not only increase the drainage efficiency, but also reduce the probability of rainwater flowing into the underground parking layer along the upper surface of the vertical rod; by setting a structure of a reinforced support rod, reinforced support is provided under the vertical rod to improve strength, thereby preventing the vertical rod from breaking when a vehicle passes through, causing damage to the vehicle.

[0016] The following will be combined with the attached embodiment of the utility model Figure 1-2 , the technical solutions in the embodiments of the utility model are described in detail. Example 1

[0017] like Figure 1-2 As shown, the utility model is a road plate which is beneficial to the drainage of underground manholes, and comprises a manhole cover frame 1, a plurality of vertical rods 2 and a reinforced support rod 3.

[0018] The manhole cover frame 1 is a rectangular frame with a hollow middle part for fixing the vertical rods 2. All the vertical rods 2 are divided into two groups. One end of each group of vertical rods 2 is connected to the upper or lower inner wall of the manhole cover frame 1, and the other end is an inclined portion 21, which is at a certain distance from the inner wall of the opposite manhole cover frame 1. The two groups of vertical rods 2 are staggered with each other, and the spacing between adjacent vertical rods 2 is the same. The holes formed by the spacing are used for drainage, and the fixed ends of adjacent vertical rods 2 are located on the inner walls on opposite sides. The manhole cover frame 1 and the vertical rods 2 are integrally formed.

[0019] The inclined portion 21 is formed into a downward slope by cutting off part of the upper surface of the vertical rod 2, and because there is a certain distance between the inclined portion 21 and the side wall, the inclined portion 21 is suspended in the air as a whole. When rainwater passes through, part of it will fall directly into the manhole from the gap between the inclined portion 21 and the manhole cover frame 1, and the other part will flow along the upper surface of the vertical rod 2, pass through the inclined portion 21 and then fall into the manhole, thereby reducing the probability of rainwater flowing into the underground parking layer; at the same time, since the vertical rod 2 is only connected to the inner wall of one side of the manhole cover frame 1 and has a certain distance from the inner wall of the other side, the drainage area is increased and the drainage efficiency is improved. Furthermore, since the inclined portion 21 is inclined downward, the drainage efficiency is also increased.

[0020] The lower surfaces of both side edges of the manhole cover frame 1 are concave to form a first slot 11. The two ends of the reinforcing support rod 3 are respectively inserted into the first slots 11 and fixed by a connecting piece 4. The connecting piece 4 is a hexagonal bolt. The inner wall of the first slot 11 is provided with a threaded hole matching the hexagonal bolt. The two ends of the reinforcing support rod 3 are concave to form a countersunk hole 31 for passing the hexagonal bolt. After the hexagonal bolt passes through the countersunk hole 31, it is threadedly connected to the first slot 11 to fix the reinforcing support rod 3 and the manhole cover frame 1.

[0021] After being fixed, the hexagonal bolt is completely buried in the countersunk hole 31. By closing and plugging the countersunk hole 31, the hexagonal bolt can be sealed to prevent water seepage and rust. The specific sealing and plugging measures are not limited here.

[0022] After the connecting piece 4 is fixed, the strengthening support rod 3 fits with the lower surface of the vertical rod 2, and the fitting part is concave to form a second slot 22. The strengthening support rod 3 is inserted into the second slot 22. The strengthening support rod 3 is flush with the lower surface of the vertical rod 2, and the upper surface of the strengthening support rod 3 is convex to form a plurality of limiting blocks 32. Each limiting block 32 is located between two adjacent vertical rods 2, and the side walls of the limiting blocks 32 are fitted with the vertical rod 2. Therefore, two adjacent limiting blocks 32 will clamp the vertical rod 2 therebetween. The strengthening support rod 3 is engaged with the second slot 22, and the limiting clamping of the vertical rod 2 by the limiting blocks 32 makes the vertical rod 2 more stable and will not shake easily.

[0023] The cross section of the limit block 32 is in a semicircular arc shape, and the arc guides rainwater so that it quickly falls into the well, avoiding large amounts of siltation and resulting in poor drainage.

[0024] A method for using a road plate that is beneficial to draining water from a basement well in this embodiment is as follows:

[0025] After the road plate is installed, it is placed above the manhole. Since it is supported by the reinforced support rod 3, the overall strength will not differ too much, and the normal passage of vehicles will not be affected.

[0026] When it is rainy and cloudy, rainwater flows down the ramp of the basement and flows above the road slab. Since only one side of the vertical bar 2 is connected to the manhole cover frame 1 and the other side is at a certain distance from the manhole cover frame 1, the drainage area is increased and the drainage efficiency is improved. In addition, part of the rainwater will flow along the upper surface of the vertical bar 2 to the inclined portion 21. Since the inclined portion 21 is inclined downward, the rainwater is guided and falls quickly into the manhole, which also improves the drainage efficiency to a certain extent. At the same time, the inclined portion 21 is at a distance from the inner wall of the manhole cover frame 1. Therefore, most of the rainwater will flow along the upper surface of the vertical bar 2 through the inclined portion 21 and directly fall into the manhole, greatly reducing the probability of rainwater entering the parking layer of the basement.

[0027] The above embodiments are only for illustrating the technical idea of ​​the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
