Description

Technical Field

[0001] The utility model relates to the technical field of roadbed drainage, in particular to a highway roadbed anti-settling drainage device. Background Art

[0002] The roadbed of a highway refers to the foundation of the road surface, which is a geotechnical structure formed by excavation or filling. Water can cause serious damage to the roadbed, resulting in a decrease in the bearing capacity of the roadbed, and settlement and deformation of the road surface. Therefore, it is necessary to install drainage devices on both sides of the roadbed for drainage. When constructing in areas with excessive groundwater, it is necessary to install geotextiles in the drainage devices to allow groundwater to seep into the drainage devices for discharge, so as to prevent it from infiltrating into the roadbed.

[0003] The current drainage device has multiple seepage holes in the drainage channel, and then uses geotextiles to penetrate the water into the drainage channel. However, the geotextile has the ability of two-way penetration. When it rains heavily, the water level in the drainage channel rises. At this time, the water in the drainage channel may penetrate into the roadbed through the geotextile, causing soil erosion. Long-term penetration may have the risk of subsidence. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a highway roadbed anti-settling drainage device which can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A highway subsidence prevention and drainage device comprises: drainage channels symmetrically arranged on both sides of a roadbed body, and also comprises: a plurality of seepage ports equidistantly arranged on a side of the drainage channel close to the roadbed body; a geotextile arranged on one side of the seepage port; a fixed plate fixed in the drainage channel, and the fixed plate is arranged on a side close to the seepage port; a plurality of chute groups arranged on the fixed plate; a floating block sliding between two adjacent chute groups, and the floating block is sealingly and slidably connected to the fixed plate; a fitting plate fixedly arranged on the lower side of the fixed plate, and the fitting plate is fitted with the floating block; a through hole arranged on a side of the floating block close to the seepage port; and a baffle arranged on the upper side of the drainage channel.

[0007] In order to prevent rainwater from splashing onto the geotextile, further, an inclined plate is fixedly connected in the drainage channel, and the inclined plate is arranged on one side of the drainage channel close to the seepage port.

[0008] Preferably, a grille is fixedly connected inside the water seepage opening.

[0009] In order to facilitate sealing of the water seepage opening, preferably, a baffle is fixedly connected to the fixed plate, and the baffle matches the floating block.

[0010] In order to facilitate the limiting of the floating block, further, the floating block is symmetrically fixedly connected with a limiting block, the baffle is symmetrically fixedly connected with a fixing block, and a slot matching the limiting block is provided between the fixing block and the baffle.

[0011] In order to improve the sealing effect between the floating block and the baffle, further, sealing strips are provided on the lower side of the slot and the baffle.

[0012] Compared with the prior art, the utility model provides a highway roadbed anti-settling drainage device, which has the following beneficial effects:

[0013] 1. The anti-subsidence drainage device for the highway roadbed, when there is a lot of water in the drainage channel, the water level in the drainage channel rises, and the floating block moves up under the action of buoyancy. At this time, the floating block cooperates with the fixed plate to block the seepage outlet, thereby effectively preventing the water in the drainage channel from reversely infiltrating into the roadbed body and causing it to settle.

[0014] 2. The anti-subsidence drainage device for the highway roadbed, through the setting of the inclined plate, allows the water flowing down from the retaining cover to fall onto the inclined plate, and then slide into the drainage channel, thereby effectively splashing rainwater to the seepage port.

[0015] 3. The anti-subsidence drainage device for the highway roadbed, when the water level in the drainage channel rises to a certain height, the floating block moves up to seal and contact with the baffle to form a relatively sealed space. At this time, it can prevent the water level in the drainage channel from being too high and entering the seepage port, thereby effectively preventing the roadbed from subsidence. The setting of the limit block, slot and sealing strip can effectively limit the floating block and effectively improve its sealing effect to prevent water from penetrating into the roadbed.

[0016] The parts not involved in the device are the same as the prior art or can be implemented by using the prior art. The utility model effectively prevents the water in the drainage channel from reversely osmotic into the road base body and causing its sedimentation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1: Reference Figure 1-Figure 4 The highway roadbed anti-subsidence drainage device includes: a drainage channel 1 symmetrically arranged on both sides of a roadbed body 3, and also includes: a plurality of seepage ports 101, which are equidistantly opened on the side of the drainage channel 1 close to the roadbed body 3; a geotextile 102, which is arranged on one side of the seepage port 101; a fixed plate 2, which is fixed in the drainage channel 1, and the fixed plate 2 is arranged on the side close to the seepage port 101; a plurality of chute groups 201, which are opened on the fixed plate 2; a floating block 203, which slides between two adjacent chute groups 201, and the floating block 203 is sealed and slidably connected with the fixed plate 2; a bonding plate 202, which is fixedly arranged on the lower side of the fixed plate 2, and the bonding plate 202 is bonded with the floating block 203; a through hole 205, which is opened on the side of the floating block 203 close to the seepage port 101; and a cover 105, which is arranged on the upper side of the drainage channel 1.

[0024] An inclined plate 104 is fixedly connected inside the drainage channel 1 , and the inclined plate 104 is arranged on one side of the drainage channel 1 close to the water seepage port 101 .

[0025] A grille 103 is fixedly connected inside the water seepage opening 101 .

[0026] When the road base body 3 is drained, the water on the surface of the road base body 3 enters the drainage channel 1 through the retaining cover 105 for drainage. At the same time, when the groundwater penetrates from the bottom to the top, it penetrates into the drainage channel 1 through the geotextile 102 to prevent the road base body 3 from being affected by the groundwater and sinking.

[0027] When it rains heavily and a lot of water accumulates in the drainage channel 1, the water level in the drainage channel 1 rises. At this time, the floating block 203 moves up under the action of buoyancy. At this time, the floating block 203 cooperates with the fixed plate 2 to block the seepage port 101, thereby effectively preventing the water in the drainage channel 1 from reversely permeating into the road base body 3 and causing it to settle.

[0028] By setting the inclined plate 104 , the water flowing down from the blocking cover 105 falls onto the inclined plate 104 and then slides into the drainage channel 1 , so that the rainwater splashes to the water inlet 101 effectively.

[0029] Example 2: Reference Figure 1-Figure 4 The highway roadbed anti-subsidence drainage device is basically the same as that of Example 1. Furthermore, a baffle 206 is fixedly connected to the fixed plate 2, and the baffle 206 matches the floating block 203.

[0030] The floating block 203 is symmetrically fixedly connected to the limiting block 204 , the baffle plate 206 is symmetrically fixedly connected to the fixing block 207 , and a slot 208 matching the limiting block 204 is provided between the fixing block 207 and the baffle plate 206 .

[0031] The slot 208 and the lower side of the baffle 206 are both provided with sealing strips 209 .

[0032] When the water level in the drainage channel 1 rises to a certain height, the floating block 203 moves up to be in sealing contact with the baffle 206 to form a relatively sealed space. At this time, the water level in the drainage channel 1 can be prevented from being too high and entering the seepage port 101, thereby effectively preventing the roadbed from settling. The floating block 203 is effectively limited by the setting of the limit block 204, the slot 208 and the sealing strip 209, and its sealing effect is effectively improved to prevent water from penetrating into the roadbed body 3.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
