Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a drainage structure in a culvert with a cover plate. Background Technology

[0002] In the daily operation, management, and maintenance of culverts and underpasses, seepage frequently occurs at the joints of cover plates and settlement joints, affecting the strength and durability of the structure. Addressing seepage in culverts and underpasses has become a challenge in operation and maintenance and requires a solution. Currently, most seepage repairs involve using sealant, cement mortar, or trenching for drainage. However, observations by the maintenance station have shown that these methods are ineffective, have poor durability, and result in recurring seepage. Furthermore, excessively deep trenching exposes reinforcing steel, compromising structural safety. Utility Model Content

[0003] This invention solves the problem of water seepage in culvert covers by setting a water channel at the bottom of the culvert cover where water is prone to seepage and extending the water channel downward along the side wall surface to drain the water in the water channel into the drainage ditch.

[0004] This utility model discloses a drainage structure for a culvert with a cover plate. The culvert includes a pair of side walls on a foundation and a culvert cover plate covering the top of the pair of side walls. The drainage structure includes a drainage ditch on the foundation, a water inlet channel fixed to the bottom seepage point of the culvert cover plate, and a drainage channel for draining water from the water inlet channel into the drainage ditch. The two ends of the drainage ditch extend to the two side walls respectively. At least one end of the water inlet channel is introduced into one of the side walls. The drainage channel extends downward along the surface of one of the side walls to form a drainage end that leads into the drainage ditch.

[0005] A further improvement of this utility model is that the water diversion channel includes a second water diversion channel disposed on the same side as the drainage channel and extending along the width direction of the corresponding side wall, and at least one first water diversion channel. The culvert cover plate is spliced ​​together from at least two adjacent sub-plates. The at least two sub-plates are arranged sequentially along the length direction of the side wall. A first water diversion channel is provided at the splice joint of each pair of adjacent sub-plates. The first water diversion channel extends along the direction of the splice joint and connects to the second water diversion channel. The drainage channel is connected to the second water diversion channel.

[0006] A further improvement of this utility model is that both the water inlet trough and the drainage trough are cut from PVC pipes.

[0007] A further improvement of this utility model is that it also includes a plurality of first clamps spaced on the surface of the first water diversion channel, and the first water diversion channel is fixed to the bottom of the culvert cover plate by the plurality of first clamps.

[0008] A further improvement of this utility model is that the culvert cover plate is fixed with a wall-embedded component for fixing the first clamp.

[0009] A further improvement of this utility model is that it also includes a plurality of second clamps spaced on the surface of the second water diversion channel, and the second water diversion channel is fixed between the culvert cover plate and the corresponding side wall by the plurality of second clamps.

[0010] A further improvement of this utility model is that both the culvert cover plate and the side wall are fixed with embedded wall components for fixing the second clamp.

[0011] A further improvement of this utility model is that sealant is provided at the connection between the first water diversion channel and the culvert cover plate, the connection between the second water diversion channel and the culvert cover plate and the corresponding side wall, and the connection between the drainage channel and the corresponding side wall.

[0012] This invention solves the problem of water seepage in culvert covers by installing a water-diverting channel at the bottom of the culvert cover where water is prone to seepage, and extending the channel downwards along the sidewall surface to drain the water into a drainage ditch. By using a water-diverting channel instead of the existing method of cutting grooves for drainage, the invention avoids damage to the culvert structure itself, provides longer-lasting waterproofing after construction, and reduces the likelihood of repeated leakage.
