Description

Technical Field

[0001] The utility model belongs to the technical field of slope drainage, and in particular relates to a drainage flower pipe used for slope drainage. Background Art

[0002] Drainage is one of the key measures for slope control. Large landslides exert immense downward forces, making simple anti-slide piles both expensive and ineffective. Furthermore, under these immense downward forces, the slope often shears drainage pipes, causing them to fail and introducing groundwater into the sliding bed, detrimental to slope stability. Therefore, it is necessary to improve existing drainage pipe designs, reduce failure rates, improve drainage effectiveness, and enhance slope stability.

[0003] At present, the existing technology installs a hose in the drainage flower pipe. After the drainage flower pipe is cut, the water discharged into the drainage flower pipe continues to be introduced into the drainage flower pipe below through the high-toughness hose. However, the hose is installed in the existing technology using sealant, which makes the hose easy to fall off. Utility Model Content

[0025] like Figures 1-6 As shown, a drainage flower pipe for slope drainage is provided, comprising a flower pipe body 1, a hose 2 and a connecting structure; the hose 2 is installed inside the flower pipe body 1 through the connecting structure.

[0026] like Figure 1 As shown, the flower tube body 1 includes a first connecting section 11 and a second connecting section 12; a plurality of water-permeable holes 13 are provided on the surface of the first connecting section 11; the first connecting section 11 and the second connecting section 12 are usually integrally formed, and the flower tube body 1 is usually made of hard PVC or medium-density PE; the length of the second connecting section 12 is set according to the distance from the drainage hole or drainage gallery wall through the slide bed to the sliding surface.

[0027] like Figure 2 As shown, a coil spring 21 is embedded in the hose 2. For details, reference may be made to the prior art. The hose 2 may have a certain taper from top to bottom, that is, the end of the hose 2 close to the connection structure is the large-diameter end, thereby reducing the difficulty of assembly; the material of the hose 2 may be reinforced soft PVC material or low-density PE material.

[0028] like Figure 2-Figure 6 As shown, the connection structure includes a first fixing ring 3, a second fixing ring 4, a limiting rod 5, and an automatic unfolding component 6; the second fixing ring 4 is fixed to the inner wall of the flower tube body 1, and the connection method of the second fixing ring 4 and the second connecting section 12 refers to the existing technology. As an option, the second fixing ring 4 can be directly integrally formed with the flower tube body 1; the first fixing ring 3 is fixedly connected to the head of the hose 2, and the first fixing ring 3 is T-shaped. The small diameter end of the first fixing ring 3 is adapted to the large diameter end of the hose 2, and the outer diameter of the large diameter end of the first fixing ring 3 is smaller than the outer diameter of the second fixing ring 4; the connection method of the first fixing ring 3 and the hose 2 can refer to the existing technology. As an option, the first fixing ring 3 and the hose 2 are connected by a conversion joint and adhesive; when the hose 2 is installed in place through the connection structure, the first fixing ring 3 is located in the second connecting section 12, and the top of the limiting rod 5 is close to the border surface of the first connecting section 11 and the second connecting section 12.

[0029] A first through hole 31 is provided on the first fixing ring 3, and a second through hole 41 is provided on the second fixing ring 4; the first through hole 31 corresponds to the second through hole 41 one by one; the limiting rod 5 is slidingly connected to the first through hole 31, and the automatic deployment component 6 is located at the bottom of the limiting rod 5; the automatic deployment component 6 can enter the second through hole 41 in a retracted state, and after passing through the second through hole 41, it is in an automatically expanded state; when the automatic deployment component 6 is in the expanded state, the cross-sectional area of ​​the automatic deployment component 6 is greater than the cross-sectional area of ​​the second through hole 41.

[0030] When in use, the automatic deployment component 6 remains in a retracted state, and the hose 2 and the first fixing ring 3 are inserted into it from one end of the floral tube body 1: when the first fixing ring 3 abuts against the second fixing ring 4, and the first through hole 31 is opposite to the second through hole 41, the limiting rod 5 is pressed to make the limiting rod 5 and the automatic deployment component 6 pass through the second through hole 41. When the automatic deployment component 6 completely passes through the second through hole 41, it automatically deploys, thereby preventing the first fixing ring 3 from falling off from the second fixing ring 4; the overall structure is simple, easy to install, and the connection structure has high stability.

[0031] like Figure 4As shown, in this embodiment, the automatic deployment component 6 includes at least two deployment arms 61; the bottom of the limit rod 5 is equipped with a hinge seat 62 corresponding to the deployment arm 61; the end of the deployment arm 61 close to the limit rod 5 is hinged on the hinge seat 62, and a torsion spring 63 is also connected between the deployment arm 61 and the hinge seat 62; the bottom of the hinge seat 62 is provided with a limit plate 64 that blocks the bottom of the hinge seat 62, and the limit plate 64 and the hinge seat 62 can be formed as one piece, and the setting of the limit plate 64 can prevent the deployment arm 61 from rotating downward; one end of the torsion spring 63 is connected to the deployment arm 61, and the other end is connected to the hinge seat 62; when the torsion spring 63 is in a free state, the deployment arm 61 and the limit rod 5 are perpendicular to each other; the structure of the torsion spring 63 and the connection method with other components can refer to the existing technology. There is one or two torsion springs 63. When there are two torsion springs 63, they are located on opposite sides of the deployment arm 61 respectively.

[0032] In this embodiment, there are at least two limit rods 5 and automatic deployment components 6, and they correspond one to one; the two limit rods 5 are respectively located on the left and right sides of the axis of the first fixed ring 3. Of course, there can also be three or four limit rods 5, and they surround the first fixed ring 3.

[0033] In this embodiment, in order to facilitate the automatic deployment component 6 to maintain a contracted state, the first through hole 31 is a stepped hole, wherein the small diameter end of the first through hole 31 is adapted to the outer diameter of the limiting rod 5, the limiting rod 5 is slidably connected to the small diameter section of the first through hole 31, and the large diameter end is adapted to the second through hole 41, that is, when the hose 2 has not entered the flower tube body 1, the automatic deployment component 6 contracts under the action of external force and is limited in the large diameter end of the first through hole 31, thereby maintaining contraction.

[0034] Furthermore, a top plate 51 is provided at the head of the limiting rod 5; the connection structure also includes a reset spring 7, which is sleeved on the upper part of the limiting rod 5, and one end of the reset spring 7 is connected to the top plate 51, and the other end is connected to the surface of the first fixing ring 3 facing away from the second fixing ring 4; when the automatic deployment component 6 is in the deployed state and abuts against the surface of the second fixing ring 4 facing away from the first fixing ring 3, the reset spring 7 is in a compressed state; the setting of the reset spring 7 can make the limiting rod 5 always have an upward force, so that the deployment arm 61 can continuously abut against the lower surface of the second fixing ring 4, thereby improving the connection strength and connection sealing of the first fixing ring 3 and the second fixing ring 4. At the same time, since the small diameter end of the first through hole 31 is adapted to the outer diameter of the limiting rod 5, the connection sealing of the limiting rod 5 and the first fixing ring 3 is ensured.

[0035] The junction of the first connecting section 11 and the second connecting section 12 is equivalent to the preset cutting position of the flower tube body 1. After the flower tube body 1 is cut, the water discharged into the flower tube body 1 continues to be introduced into the second connecting section 12 through the high-toughness hose 2; the high toughness of the hose 2 can prevent it from being pulled and damaged, and the coil spring 21 in the hose 2 can effectively ensure that the hose 2 maintains water flow under the pressure of the covering soil.
