Technical Field
[0001] The utility model relates to the field of drainage geotextiles, in particular to drainage special-shaped self-adhesive geotextiles. Background Art
[0002] In the field of construction, drainage special-shaped self-adhesive geotextile is applied to the roof of underground garages. It is constructed directly on the waterproof membrane. After the construction is completed and the planting soil is backfilled, it is used for greening. The main function is to block the soil and filter the seepage water through the geotextile of the drainage special-shaped self-adhesive geotextile, and drain the water through the overhead drainage channel inside the drainage special-shaped self-adhesive geotextile.
[0003] The existing drainage shaped sheet self-adhesive geotextile includes a drainage shaped sheet body and a geotextile; the drainage shaped sheet body is composed of a plurality of protrusions arranged on a drainage flat plate and a drainage horizontal plate, and an overhead drainage channel is formed between the plurality of protrusions, which is applied to a waterproof layer and can become a flexible protective layer for the waterproof layer. The top of the protrusion is coated with glue and bonded with the geotextile to improve the supporting strength of adjacent protrusions and the geotextile.
[0004] However, the existing self-adhesive geotextiles for drainage shaped sheets have defects. When the geotextiles on the drainage shaped sheet body are subjected to large forces locally, the adhesive points are prone to debonding traps, and thus they are easily collapsed in the drainage channels between the protrusions, causing blockage of the drainage channels and affecting the drainage effect. Even worse, it is easy to cause moisture seepage on the roof and affect the house structure. Utility Model Content
[0005] The purpose of the utility model is to provide a drainage special-shaped self-adhesive geotextile in order to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drainage special-shaped self-adhesive geotextile, comprising a bottom layer, a protruding platform with a truncated cone structure is integrally formed on the top of the bottom layer, a geotextile is laid on the top of the protruding platform, and the protruding platform and the geotextile are reinforced by a reinforcement component; the reinforcement component is used to improve the connection force between the protruding platform and the geotextile to prevent the geotextile from sliding and dislocating; the reinforcement component comprises a protruding column integrally formed at the center of the top of the protruding platform, a downwardly concave circular groove is formed on the top of the protruding column, a connecting column is connected to the inner wall of the circular groove, and a baffle is integrally formed on the top of the protruding column.
[0007] As a further solution of the utility model: the inner wall of the circular groove is formed with an internal thread, and the cylindrical outer wall of the connecting column is formed with an external thread engaged with the internal thread.
[0008] As a further solution of the utility model: the lower half of the connecting column is in a cone-shaped structure, and the apex of the cone-shaped structure faces downward.
[0009] As a further solution of the utility model: the diameter of the baffle is larger than the inner diameter of the circular groove.
[0010] As a further solution of the utility model: a circulation channel for water to circulate between the plurality of protruding platforms.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. By setting up a reinforcement mechanism, the reinforcement mechanism connects the geotextile to the protruding platform at multiple points. The multi-point connection method can disperse the force to each point connected to the reinforcement mechanism when the geotextile is subjected to stress, thereby improving the connection firmness of the geotextile and avoiding the collapse of the geotextile.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1 to Figure 3 In the embodiment of the utility model, the drainage special-shaped self-adhesive geotextile includes a bottom layer 1, a protruding platform 2 with a truncated cone structure is integrally formed on the top of the bottom layer 1, a geotextile 3 is laid on the top of the protruding platform 2, and the protruding platform 2 and the geotextile 3 are reinforced by a reinforcement component; the reinforcement component is used to improve the connection force between the protruding platform 2 and the geotextile 3 to prevent the geotextile 3 from sliding and dislocating; the reinforcement component includes a protruding column 4 integrally formed at the center of the top of the protruding platform 2, a downwardly concave circular groove is formed on the top of the protruding column 4, a connecting column 5 is connected to the inner wall of the circular groove, and a blocking piece 6 is integrally formed on the top of the protruding column 4.
[0019] In this embodiment: first, the bottom layer 1 is laid at a preset position through an adhesive strip. As the bottom layer 1 is laid, the protruding platform 2 is unfolded accordingly. Then, the geotextile 3 is laid on the protruding platform 2. After laying, the geotextile 3 is fixed using a reinforcement component. The connection points are multi-point and evenly distributed, thereby avoiding the risk of collapse of the geotextile 3.
[0020] Please refer to Figure 2 and Figure 3 The inner wall of the circular groove is formed with an internal thread 7, and the cylindrical outer wall of the connecting column 5 is formed with an external thread engaged with the internal thread 7. The lower half of the connecting column 5 is a cone-shaped structure with the vertex of the cone-shaped structure facing downward.
[0021] In this embodiment: after the geotextile 3 is laid, the connecting column 5 is aligned with the circular groove, and then the connecting column 5 is pressed down, and the lower half of the vertebral body of the connecting column 5 pierces the geotextile 3 and is inserted into the circular groove. When the cylindrical part of the connecting column 5 is aligned with the circular groove, the baffle 6 is rotated, and the baffle 6 drives the connecting column 5 and the external thread of its outer wall, and the rotating external thread is engaged with the internal thread 7 until the external thread and the internal thread 7 are completely engaged. At this time, the bottom end of the baffle 6 is tightly attached to the top surface of the protruding column 4, thereby preventing the geotextile 3 from resetting upward;
[0022] When the geotextile 3 is locally subjected to excessive downward pressure, the geotextile 3 will disperse the force to the connection points connected to the reinforcement mechanism, thereby preventing the geotextile 3 from collapsing and causing blockage of the trough.
[0023] Please refer to Figure 2 , the diameter of the baffle 6 is larger than the inner diameter of the circular groove.
[0024] In this embodiment, the external thread is completely engaged with the internal thread 7, and the bottom end of the blocking piece 6 is in close contact with the top end surface of the protruding column 4, thereby preventing the geotextile 3 from resetting upward.
