Description

Technical Field

[0001] This utility model belongs to the field of pipe gallery technology, and in particular relates to a drainage structure for branch outlets of pipe galleries. Background Technology

[0002] Pipeline branch points refer to the locations where internal pipelines in a utility tunnel connect with external directly buried pipelines, and are typically located near intersections and land parcels. Due to limited vertical space within the utility tunnel, the usual practice for pipelines to exit is to partially elevate the tunnel and extend them from one or both sides of the sidewall, depending on the pipeline requirements along the tunnel. However, this increases the overall burial depth of the tunnel and raises support costs.

[0003] Another approach is to partially lower the floor slab of the utility tunnel at the pipeline branch point to ensure passage space for personnel. This ensures the pipeline outlet within the tunnel without increasing the overall burial depth. However, the partially lowered floor slab will collect water from the drainage ditch of the utility tunnel, causing water accumulation at the lowered floor slab at the pipeline branch point, which cannot guarantee the safety of personnel passage. Utility Model Content

[0004] In view of the defects or deficiencies in the existing technology, this utility model provides a drainage structure for the branch outlet of the pipeline in the pipe gallery, which can prevent water in the drainage ditch from flowing to the bottom plate of the pipeline branch outlet and causing water accumulation, thus ensuring the safety of personnel passage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An embodiment of this utility model provides a drainage structure for a branch outlet of a pipe gallery, including a straight section and a lower section. A drainage ditch is provided on the bottom plate of the straight section, and a drainage channel is fixed above the lower section. Both ends of the drainage channel are connected to the drainage ditch.

[0006] Furthermore, there are two drainage ditches, located on the bottom plate at the bottom of the side walls on both sides of the straight section.

[0007] Furthermore, there are two drainage channels, which are correspondingly arranged with two drainage ditches.

[0008] Furthermore, supports are installed on the bottom plate of the pipe gallery on the side away from the sidewall of the two drainage ditches, respectively, to support the water supply pipes and the reclaimed water pipes.

[0009] Furthermore, the bottom surface of the drainage trough is flush with the bottom surface of the drainage trough.

[0010] Furthermore, one side wall of the drainage trough is fixedly connected to the inner wall of the pipe gallery by screws, and the other side wall is fixedly connected to the support by screws.

[0011] Furthermore, a sealant is applied to the bottom surface of the end of the drainage channel where it meets the drainage ditch.

[0012] Furthermore, multiple supports are provided on the side walls on both sides of the lower lying section, and the multiple supports are perpendicular to the side walls on both sides of the lower lying section.

[0013] Furthermore, multiple supports are arranged side by side along the length of the lower section, and the upper surfaces of the multiple supports are located in the same plane.

[0014] Furthermore, the bottom of the drainage channel is fixedly connected to the upper surface of multiple supports.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a drainage trough above the lower section of the pipe gallery, which is connected to a drainage ditch. This allows water in the drainage ditch to be drained to the lower part of the pipe branch, causing water accumulation and ensuring the safety of personnel passage.

[0016] 2. This utility model ensures the sealing of the connection between the bottom surface of the drainage channel and the drainage ditch by applying sealant, thus preventing water in the drainage ditch from flowing through the gaps at the bottom of the drainage channel to the floor and causing water accumulation.

[0017] 3. This utility model provides multiple supports on the side walls of both sides of the lower section of the pipe gallery, which effectively support the bottom of the drainage channel and prevent the middle of the drainage channel from sinking, thus preventing poor drainage.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] A typical embodiment of this utility model is as follows: Figure 1As shown, a drainage structure for a branch outlet of a utility tunnel includes a utility tunnel body 1, which is hollow inside. The utility tunnel body 1 includes a straight section 2 and a lower section 3. The lower section 3 is located at the branch outlet of the utility tunnel, where the bottom plate of the utility tunnel is partially lowered to ensure passage space for personnel. Both ends of the lower section 3 are connected to the straight section 2, and the bottom plate of the lower section 3 smoothly transitions to the bottom plate of the straight section 2.

[0021] like Figure 2 As shown, drainage ditches 4 are provided on the bottom plates of the side walls on both sides of the straight section 2. The drainage ditches 4 are U-shaped. Support piers 5 are also provided on the bottom plates of the pipe gallery on the side of the two drainage ditches 4 away from the side wall of the pipe gallery. The two support piers 5 are used to support the water supply pipe and the reclaimed water pipe, respectively.

[0022] like Figure 3 As shown, a drainage trough 6 is provided above the lower section 3. There are two drainage troughs 6, which are corresponding to two drainage ditches 4. Both ends of the drainage trough 6 are connected to the drainage ditches 4. The bottom surface of the drainage trough 6 is flush with the bottom surface of the drainage ditches 4. By connecting the drainage trough 6 to the drainage ditches 4 of the straight section 2, the water in the drainage ditches 4 will not flow into the lower section 3, thus avoiding the accumulation of water in the lower section 3.

[0023] The longitudinal section of the drainage channel 6 is U-shaped and is made of galvanized steel sheet. The drainage channel 6 is compatible with the drainage ditch 4, and its two ends can be inserted into the drainage ditch 4 and fixedly connected to the drainage ditch 4 by screws.

[0024] Specifically, one side wall of the drainage channel 6 is fixedly connected to the inner wall of the pipe gallery by screws, and the other side wall is fixedly connected to the support 5 by screws to ensure the stability of the connection between the drainage channel 6 and the drainage ditch 4.

[0025] A sealant is applied to the bottom surface of the drain trough 6 where it meets the drain ditch 4. The sealant is a two-component polysulfide sealant, which can ensure the sealing of the connection between the drain trough 6 and the drain ditch 4 and prevent water in the drain ditch 4 from flowing from the gap at the bottom of the drain trough 6 to the bottom of the base plate and causing water accumulation.

[0026] like Figure 4 As shown, multiple supports 7 are provided on the side walls of both sides of the lower section 3. The multiple supports 7 are perpendicular to the side walls of both sides of the lower section 3. The multiple supports 7 are arranged side by side along the length of the lower section 3, and the upper surfaces of the multiple supports 7 are located in the same plane. The bottom of the drainage trough 6 is fixedly connected to the upper surfaces of the multiple supports 7. By providing multiple supports 7 on the side walls of both sides of the lower section 3, the bottom of the drainage trough 6 is effectively supported, preventing the middle of the drainage trough 6 from sinking and causing poor drainage.

[0027] This utility model involves setting a drainage trough above the lower section of the pipe gallery, and connecting the drainage trough to a drainage ditch, so that the water in the drainage ditch is discharged to the lower part of the pipeline branch plate to cause water accumulation, thus ensuring the safety of personnel passage.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
