Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a near-term and long-term drainage pipe. Background Technology

[0002] Near-term and long-term drainage pipes are special drainage pipes designed to address seasonal water volume changes. Existing near-term and long-term drainage pipes are generally divided into circular drainage pipe structures and drainage pipe structures with a flat bottom on the outer wall. Circular drainage pipes are prone to problems with insufficient backfilling at the bottom, which can lead to problems such as pipe deflection and settlement. Since the trench needs to be at the bottom during the dry season to achieve the best effect, the position of the trench will change when the pipe deflects or settles, thus affecting the drainage effect. Drainage pipe structures with a flat bottom on the outer wall can effectively solve the problem of insufficient backfilling on both sides of the bottom of circular drainage pipes and the potential for suspension. However, because the bottom of this type of drainage pipe structure is flat, a large amount of concrete needs to be poured at the bottom of the pipe to form a flat bottom structure. This method increases the self-weight of the pipe, increases the burden of transportation and handling, and increases the consumption of concrete and steel reinforcement. In view of the above-mentioned defects, this application is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a drainage pipe for both short-term and long-term applications. By setting a soil compaction component at the bottom of the pipe, the bottom of the circular pipe is fully filled with soil. This eliminates the need for a planar structure at the bottom of the pipe to avoid the problem of the pipe being suspended due to insufficient soil compaction, thereby avoiding the problem of increased pipe weight.

[0004] To address the aforementioned problems, this utility model provides a near-term and long-term drainage pipe, comprising a pipe body and a soil compaction assembly. The pipe body has an internal channel and a dry season ditch located at the bottom of the channel. Several positioning pipes are arranged on the outer circumference of the pipe body, and the axis of the positioning pipes is perpendicular to the axis of the channel. The soil compaction assembly includes at least two sets of side plates, a traction screw, and a nut. The traction screw passes through the positioning pipes, and the nut and side plates are installed on the traction screw. The two sets of side plates are located on both sides of the pipe body, and the nut is used to adjust the spacing between the two sets of side plates to achieve the soil compaction effect.

[0005] The width of the ditch in the dry season is smaller than that of the channel, which maintains a higher flow velocity when the drainage flow is low in the dry season, significantly reducing the probability of siltation and improving the drainage efficiency in the dry season; at the same time, it maintains the overall water carrying capacity of the channel during the rainy season.

[0006] It should be noted that there is no limit to the length of the positioning tube. Its length can be greater than or less than the diameter of the tube. It can be in the form of a sheet or a tube, and it only needs to have a through hole that can be used for positioning and for the traction screw to pass through.

[0007] When installing this drainage pipe, soil is filled between the two side plates and then the soil layer is compacted using the side plates, thus forming a compact soil layer at the bottom of the pipe. This solves the problem of incomplete filling at the bottom of traditional round pipes. Compared to casting the bottom of the pipe into a square to form a flat surface, it does not increase the weight of the pipe or the amount of concrete used.

[0008] According to one embodiment of the present invention, the two sets of side plates include a fixed plate connected to one end of the traction screw and a movable plate that can move along the traction screw, and the nut is disposed on the outside of the movable plate.

[0009] According to one embodiment of the present invention, each soil compaction assembly includes at least two sets of traction screws to ensure the compaction of the soil by the side plates.

[0010] Optionally, the positioning tube body is integrally cast with the tube body, or the positioning tube body is installed on the tube body through a connector.

[0011] According to one embodiment of the present invention, the height of the side plate is less than or equal to the radius of the tube.

[0012] Optionally, the positioning tube is disposed inside the tube wall, that is, the positioning tube does not protrude from the surface of the tube, or the positioning tube protrudes from the surface of the tube. This method will not affect the strength of the tube.

[0013] According to one embodiment of the present invention, a gasket, such as a rubber gasket, is provided at the contact portion between the side plate and the pipe surface to prevent contact with the pipe surface when compacting the soil, thus avoiding damage to the pipe surface.

[0014] According to one embodiment of the present invention, the dry season ditch includes a narrowing section whose width gradually decreases from top to bottom and a semi-circular ditch disposed at the bottom of the narrowing section.

[0015] The beneficial effects of this utility model are that by setting up a soil compaction component and using traction screws and side plates for mechanical compaction, a compact soil layer is formed at the bottom of the pipe, which effectively prevents the problem of soil suspension, reduces the probability of pipe deflection and settlement, ensures the drainage effect of the trench during the dry season, solves the problem of incomplete filling at the bottom of traditional round pipes, and compared with the method of casting the bottom of the pipe into a square to form a plane, it will not increase the weight of the pipe and the amount of concrete used, reducing the burden of transportation and handling and construction costs; in addition, the side plates are in the soil layer, which can play an auxiliary role in fixing the pipe, improving structural stability and anti-settlement ability.

[0023] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0024] Example 1:

[0025] A type of drainage pipe with near-term and long-term applications, such as Figure 1 , Figure 2 It includes pipe body 1 and soil compaction components.

[0026] The pipe body 1 is equipped with a channel 11 and a dry season ditch 12 located at the bottom of the channel 11. The width of the dry season ditch 12 is smaller than the width of the channel 11. When the drainage flow is low in the dry season, it maintains a high flow velocity, significantly reduces the probability of siltation, and improves the drainage efficiency in the dry season. At the same time, it maintains the water carrying capacity of the entire channel during the rainy season.

[0027] In this embodiment, as Figure 2 The dry season ditch 12 includes a narrowing section 121 whose width gradually decreases from top to bottom and a semi-circular ditch 122 located at the bottom of the narrowing section 121. This further ensures the water passage capacity of the overall channel while playing a role in rapid drainage and reducing siltation during the dry season.

[0028] The outer circular surface of the tube body 1 is provided with several positioning tube bodies 13, and the axis of the positioning tube body 13 is perpendicular to the axis of the channel 11.

[0029] In this embodiment, the positioning tube 13 is located at the bottom of the tube 1. Optionally, the positioning tube 13 and the tube 1 are integrally cast, or the positioning tube 13 is installed on the tube 1 by means of a connector, wherein the connector can be an expansion bolt or glue.

[0030] Optionally, the positioning tube 13 is disposed inside the wall of the tube 1, that is, the positioning tube 13 does not protrude from the surface of the tube, or the positioning tube 13 protrudes from the surface of the tube 1. This method will not affect the strength of the tube.

[0031] It should be noted that the length of the positioning tube 13 is not limited. Its length can be greater than or less than the diameter of the tube 1. It can be in the form of a sheet or a tube, and it can have a through hole that can be used for positioning and for the traction screw 24 to pass through.

[0032] The soil compaction assembly includes at least two sets of side plates, two sets of traction screws 24 and nuts 23. The traction screws 24 are set through the positioning tube 13. The nuts 23 and side plates are installed on the traction screws 24. The two sets of side plates are located on both sides of the tube 1 respectively. The nuts 23 are used to adjust the spacing between the two sets of side plates to achieve the soil compaction effect.

[0033] In this embodiment, the two sets of side plates include a fixed plate 21 connected to one end of the traction screw 24 and a movable plate 22 that can move along the traction screw 24, with a nut 23 disposed on the outside of the movable plate 22.

[0034] The side plates can be made of materials such as metal plates or concrete plates, and their length is generally less than 5m. However, with more traction screws 24, the length of the side plates can be greater than 5m.

[0035] When installing this drainage pipe, soil is filled between the two side plates and then the soil layer is compacted using the side plates, thus forming a compact soil layer at the bottom of the pipe. This solves the problem of incomplete filling at the bottom of traditional round pipes. Compared to casting the bottom of the pipe into a square to form a flat surface, it does not increase the weight of the pipe or the amount of concrete used.

[0036] The height of the side plate is less than or equal to the radius of the tube body 1, and in the embodiment, the height of the side plate is not limited.

[0037] When the drainage pipe is long, multiple sets of soil compaction components can be installed.

[0038] During installation, such as Figures 3-6 First, the outer pipe of the device is placed face down in the installation groove during the dry season. Then, the traction screw 24 is inserted into the positioning pipe 13 and protrudes out. Next, the moving plate 22 is fitted onto the traction screw 24, and the nut 23 is installed. Soil is then filled into the area between the fixed plate, the moving plate, and the outer pipe. After filling, multiple workers simultaneously tighten the nut 23 to move the moving plate and compact the soil between the moving plate, the fixed plate, and the outer pipe. After compaction, tightening stops, and soil is continued to be filled into the outer pipe and the outside of the moving plate and the fixed plate, thus completing the installation of the device. The side plates also serve as reinforcement bars for fixing. During dry season operation, the water flow is small, and the narrower dry season trench allows for a relatively faster water flow, thereby reducing siltation.

[0039] Example 2:

[0040] Unlike in Embodiment 1, in this embodiment, both sets of side plates are movable plates, the traction screw 24 is a double-headed screw, and nuts are provided on the outer sides of both side plates. The distance between the two side plates can be adjusted by rotating the nuts on both sides.

[0041] Example 3:

[0042] Based on embodiment 1 or 2, a gasket, such as a rubber gasket, is provided at the contact part between the side plate and the surface of the pipe body 1 to avoid contact with the surface of the pipe body when compacting the soil, which would cause damage to the surface of the pipe body.

[0043] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
