Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete pouring pipes, in particular to a concrete pouring pipe quick connector. Background Art
[0002] Concrete-cast pipes offer advantages such as low cost, long service life, no secondary pollution, and significant steel savings. They can be used to transport fluids such as water, oil, and gas. With mature production processes, they are widely used in municipal engineering, the petrochemical industry, and other industries, generating significant market demand. Segments of concrete-cast pipe can be spliced together to form a long-distance pipe network for transporting water, oil, and gas. Pipe joints are components installed between pipes at both ends. Concrete pipes generally come in flat-end, spigot, and tongue-and-groove joints. When connecting two concrete pipes, the two pipes are inserted from both ends of the joint. Leak-proofing is achieved using methods such as cement mortar tape, wire mesh cement mortar tape, spigot-and-groove spigot, and rubber ring spigot-and-groove joints.
[0003] However, concrete pipes and joints are installed underground for use, and the soil supporting the pipes and joints is prone to loosening and loss. Because the distance between the joints is short, when the soil supporting the joints below loosens, the support force on the joints will weaken, which will cause the joints to sink and create gaps at the connection between the joints and the pipes, posing a risk of leakage when water, oil, and gas pass through.
[0004] In view of the above problems, the present utility model is proposed. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a concrete pouring pipe quick connector to solve the problems mentioned in the background technology.
[0006] In order to solve the above technical problems, the present utility model provides the following technical solutions.
[0007] The utility model provides a quick connector for concrete pouring pipes, comprising a joint pipe, wherein the inner walls of the pipe openings on both sides of the joint pipe are provided with notches of uniform depth, supports are provided in the lower middle area and the lower surface of both sides of the joint pipe, the bottom surfaces of the supports contacting the soil are planar, bottom grooves are provided on the lower surfaces on both sides of the supports, a plurality of reinforcing ribs are uniformly provided in the bottom grooves along the length direction of the supports, and a plurality of groups of steel bar holes penetrating the supports are provided on the upper surfaces on both sides of the supports;

[0015] Preferably, there are six to eight cement holes and six to eight gaskets.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] The support plays a supporting role for the joint pipe. The support can make the joint pipe more firmly placed in the concrete pipe groove. Use steel bars to pass through the steel bar holes and then deeply drive the steel bars into the soil. Bend the exposed part of the steel bars and fit them on the side of the support. In this way, multiple steel bars play a supporting role for the support and the joint pipe. Even if the soil under the joint pipe is lost or settled, the joint pipe will not settle.

[0023] 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 the embodiments.
[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.
[0025] like Figure 1-3 As shown, a quick connector for concrete pouring pipes includes a joint pipe 1. The inner walls of the pipe openings on both sides of the joint pipe 1 are provided with notches 11 of uniform depth. Two concrete pipes can be inserted from both sides of the joint pipe 1 into the notches 11. Supports 2 are provided in the lower middle area and lower surface of both sides of the joint pipe 1. The bottom surface of the support 2 contacting the soil is flat. The support 2 supports the joint pipe 1. Bottom grooves 21 are provided on the lower surfaces of both sides of the support 2. A plurality of reinforcing ribs 22 are evenly arranged at equal distances in the bottom grooves 21 along the length direction of the support 2. The reinforcing ribs 22 can enhance the structural strength of the support 2. A plurality of groups of steel bars 23 penetrating the support 2 are provided on the upper surfaces of both sides of the support 2. Steel bars can pass through the steel bars 23.
[0026] The inner wall of the notch 11 is provided with a plurality of cement holes 12 that penetrate the joint pipe 1. The cement used to connect the joint pipe 1 and the concrete pipe can enter the cement holes 12. In this way, after the cement hardens, it can be partially shaped in the cement holes 12, so that the joint pipe 1 and the concrete pipe are firmly connected. The plurality of cement holes 12 are evenly distributed at equal intervals along the inner wall of the joint pipe 1. The inner wall of the notch 11 is provided with a plurality of gaskets 13. The plurality of gaskets 13 are evenly distributed at equal intervals along the inner wall of the joint pipe 1.
[0027] A plurality of cement holes 12 and a plurality of gaskets 13 are distributed in a staggered manner.
[0028] The plurality of groups of steel bar holes 23 are staggered with the plurality of reinforcing rib plates 22 . Each group of steel bar holes 23 has two steel bar holes 23 symmetrically distributed between two adjacent reinforcing rib plates 22 .
[0029] The steel bar hole 23 includes an upper hole 231 located above and a lower hole 232 located below. The vertical axes of the upper hole 231 and the lower hole 232 are aligned. The upper hole 231 is in a truncated cone shape and the lower hole 232 is cylindrical. The small circular surface of the upper hole 231 fits the upper surface of the lower hole 232. The upper hole 231 facilitates the insertion of the steel bar into the lower hole 232.
[0030] The cement hole 12 is located in the middle of the notch 11 in the width direction, and the gasket 13 is located in the notch 11 near its outlet.
[0031] The thickness of the gasket 13 gradually decreases along the direction from the mouth of the joint pipe 1 to the middle thereof.
[0032] The plurality of reinforcing ribs 22 are symmetrically distributed with the transverse center axis of the support 2 as the symmetry axis.
[0033] There are six to eight cement holes 12 and six to eight spacers 13.
[0034] In summary, the support 2 supports the joint pipe 1. The support 2 can place the joint pipe 1 more stably in the concrete pipe groove. The steel bars are passed through the steel bar holes 23 and then deeply inserted into the soil. The exposed steel bars are bent and attached to the side of the support 2. In this way, multiple steel bars support the support 2 and the joint pipe 1. Even if the soil below the joint pipe 1 is lost or settled, the joint pipe 1 will not settle.
[0035] The concrete pipes at both ends are respectively inserted into the notched grooves 11 from both sides of the joint pipe 1. The gasket 13 makes the concrete pipes and the joint pipe 1 have an interference fit. In this way, the concrete pipes on both sides can be more firmly located in the notched grooves 11, and the cement coated on the side surfaces of the concrete pipes can partially enter the cement holes 12. After the cement is formed, it can partially fill the cement holes 12, so that the connection between the concrete pipes and the joint pipe 1 is more secure.
[0036] The support of the joint pipe 1 by the steel bars prevents the joint pipe 1 from settling easily, so that the gap between the joint pipe 1 and the concrete pipe will not bend and expand, thereby ensuring the sealing of the connection position.
[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
