Description

Technical Field

[0001] This utility model relates to the field of drainage engineering technology, and in particular to a concealed pipe salt drainage coupling tee. Background Technology

[0002] Modern underground pipe drainage technology uses large-scale mechanized pipe-laying machines, and the pipes widely used are single-wall or double-wall corrugated pipes suitable for mechanical laying. However, for a long time, there has been no matching tee fitting for single-wall or double-wall corrugated pipes.

[0003] In the construction of multi-stage concealed pipes, the connection between the suction pipe (branch line) and the collection pipe (main line) has traditionally relied on a crude technique of steel wire binding and geotextile sealing. This affects construction quality and hinders the implementation and promotion of concealed pipe salt drainage technology. Utility Model Content

[0004] This invention addresses the problems existing in the prior art by providing a concealed pipe salt drainage coupling tee, which solves the technical defects of traditional structures such as poor sealing, easy displacement, and difficult maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A concealed conduit salt drainage coupling tee includes:

[0007] The system includes a water collection pipe and a water suction pipe, which are arranged perpendicularly to each other. The water collection pipe has an opening in its wall with the same diameter as the outer diameter of the water suction pipe. The water suction pipe is vertically connected to the water collection pipe through the opening in the water collection pipe, and the installation method is "T".

[0008] A coupling limiting snap-fit ​​tee is installed at the vertical connection point between the end of the suction pipe and the collection pipe; the coupling limiting snap-fit ​​tee is a two-piece arc-shaped thin-walled structure with one end hinged; the coupling limiting snap-fit ​​tee is fitted onto the outer wall of the collection pipe and the suction pipe.

[0009] A butyl rubber surface coating is applied to the inner wall of the connector end of the coupling limiting snap tee to provide a water-stop seal at the connection point between the coupling limiting snap tee and the water collection pipe and the water suction pipe.

[0010] Preferably, the coupling limiting snap-fit ​​tee includes an annular sealing plate, a connecting snap, a mating hinge, and an inner ring retaining pattern. The annular sealing plate of the coupling limiting snap-fit ​​tee consists of two pieces, one end of which is connected by the mating hinge, and is installed on the outer wall of the connection between the water collection pipe and the water suction pipe via an opening and closing mechanism. The coupling limiting snap-fit ​​tee achieves closed limiting through the connecting snap. The inner wall of the coupling limiting snap-fit ​​tee is provided with inner ring retaining patterns that respectively match the water collection pipe and the water suction pipe.

[0011] Preferably, the annular sealing plate is a two-piece, openable, arc-shaped, thin-walled "T"-shaped tee structure. The annular sealing plate has an inner ring groove, which comes in two sizes to fit the water collection pipe and the water suction pipe respectively.

[0012] Preferably, the water collecting pipe is a non-perforated corrugated pipe with uniformly distributed corrugations of the same depth on its outer wall. The water suction pipe is a perforated corrugated pipe with uniformly distributed corrugations of the same depth on its outer wall. The protrusion height of the inner ring of the annular sealing plate is consistent with the corrugation depth of both the water collecting pipe and the water suction pipe, forming a nested coupling.

[0013] Preferably, the butyl rubber surface coating is applied to the inner wall of the coupling limiting buckle tee to increase the sealing of the coupling surface.

[0014] Compared with the prior art, this utility model provides a concealed pipe salt drainage coupling tee, which has the following beneficial effects:

[0015] 1. Compared with traditional steel wire binding and geotextile sealing, this connection method greatly improves the sealing performance and prevents soil particles from flowing into the underground pipe from the interface gaps and causing blockage.

[0016] 2. Compared with traditional steel wire binding and geotextile sealing, this connection method greatly improves the structural stability. The tee corrugated and corrugated pipe are coupled to prevent the underground pipe from detaching under external force.

[0017] 3. This device uses a salt-coupled tee, eliminating the need to cut the concealed pipe. Only a hole needs to be drilled at the top of the water collection pipe, and the coupling tee is wrapped around the outside of the concealed pipe and locked in place by clips. The entire installation process is unaffected by working with water, reducing construction difficulty, simplifying construction, lowering costs, and improving construction quality and safety.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0026] Example 1:

[0027] Reference Figure 1-5 A concealed pipe salt drainage coupling tee includes a water collection pipe 1, a water suction pipe 2, a coupling limiting buckle tee 3, and a butyl rubber surface coating 4.

[0028] The water collection pipe 1 is made of PE corrugated pipe with a diameter of 160mm, and its outer wall is provided with evenly distributed annular corrugations. The water suction pipe 2 is a PE pipe with a diameter of 80mm. A circular through hole is opened in the center of the water collection pipe 1. The water suction pipe 2 is vertically inserted into the hole of the water collection pipe 1 by a "T" shaped embedding method, and the outer wall of the water suction pipe 2 is tightly fitted to the opening of the water collection pipe 1.

[0029] A coupling limiting buckle tee 3 is installed on the outer wall at the connection between the water collection pipe 1 and the water suction pipe 2 to form a stable support structure.

[0030] The coupling limiting snap-fit ​​tee 3 is composed of two annular sealing plates 101 connected by a hinge 103, and is made of PE. When closed, the two parts are locked together by a connecting snap 102. The inner wall of the coupling limiting snap-fit ​​tee 3 has several inner ring grooves 104. The corrugation depth of the part that fits into the water collection pipe 1 in the horizontal direction is the same as the corrugation depth of the water collection pipe 1, and the corrugation depth of the part that fits into the water suction pipe 2 in the vertical direction is the same as the corrugation depth of the water suction pipe 2. After nesting, it forms an interlocking engagement with the corrugations of the water collection pipe 1 and the water suction pipe 2 to prevent axial displacement.

[0031] Furthermore, the coupling limiting snap-fit ​​tee 3 has a butyl rubber surface coating 4 inside, with an initial thickness of 1 mm, which is compressed to 0.7 mm after installation. The butyl rubber surface coating 4 is embedded in the inner wall groove of the coupling limiting snap-fit ​​tee 3, covering the coupling gap between the water collection pipe 1 and the water suction pipe 2, forming a double seal.

[0032] Example 2:

[0033] Reference Figure 1-5 Similar to Example 1, but further, the corrugation depth of the water collection pipe 1 used inside the device can be adjusted according to the actual situation, and the corrugation of the inner ring 104 is simultaneously deepened to enhance the anti-torsion performance.

[0034] Furthermore, the radius of curvature of the annular sealing plate 101 of the coupling limit buckle 3 matches the outer diameter of the water collection pipe 1 and the water suction pipe 2 with an error of ≤1%, ensuring that there are no gaps on the mating surfaces.

[0035] Furthermore, the initial thickness of the butyl rubber surface coating 4 is adjusted to 2mm, and after installation it is compressed to 1.4mm (compression rate 30%), which is suitable for high-pressure drainage scenarios.

[0036] The specific working process of this device is as follows:

[0037] During underground drainage, water flows through the suction pipe 2 to the tee position, and then enters the main pipe through the vertical opening of the collection pipe 1. The interlocking structure of the coupling limiting snap tee 3 resists the impact of water flow, and the compression deformation of the internal butyl rubber surface coating 4 ensures that the interface is leak-free. When maintenance is required, the connecting snap 102 can be opened, the coupling limiting snap tee 3 can be removed and replaced, and the installation can be easily and reliably completed even in a wet environment.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
