Description

Technical Field

[0001] The utility model relates to the technical field of composite corrugated drainage mats, in particular to a composite corrugated drainage mat. Background Art

[0002] The composite corrugated drainage mat is made of three layers combined and heat-sealed at one time. The upper layer is the water filtration part, the middle layer is an effective drainage part formed by fine filaments with "W"-shaped longitudinal drainage cavities and filament-shaped transverse transparent structures, and the lower layer is the water filtration layer (sometimes a water-blocking layer depending on the project needs).

[0003] When the composite corrugated drainage mat is being laid, the joints of the composite corrugated drainage mat at both ends are simply overlapped. As a result, during the subsequent filling operation, the composite corrugated drainage mat is easily offset or the ends are lifted due to force, resulting in gaps at the joints of the composite corrugated drainage mat. Based on this, a composite corrugated drainage mat is provided. Utility Model Content

[0013] The elastic barbed hooks on the top of the bottom sheet pierce the nonwoven geotextile at the bottom, and the elastic barbed hooks on the bottom of the top sheet pierce the nonwoven geotextile at the top. The elastic barbed hooks piercing the nonwoven geotextile can further increase the connection force between the nonwoven geotextile and the bottom sheet and the top sheet.

[0022] 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.

[0023] See also Figures 1 to 3 In the embodiment of the utility model, a composite corrugated drainage mat includes a composite corrugated drainage mat 1 composed of a three-dimensional polypropylene mesh mat 101 and a non-woven geotextile 102. The non-woven geotextile 102 is symmetrically heat-sealed and fixed to the upper and lower ends of the three-dimensional polypropylene mesh mat 101. The two composite corrugated drainage mats 1 are connected and fixed by an assembly component 2.

[0024] The assembly component 2 includes a splicing unit and a reinforcement unit;

[0025] The splicing unit is used to realize the splicing and clamping of two composite corrugated drainage mats 1;

[0026] The reinforcement unit is used to further increase the connection force between the splicing unit and the composite corrugated drainage mat 1;

[0027] The splicing unit includes a bottom sheet 201, a 7-shaped card seat 202, a top sheet 203, and a cone head card block 204;

[0028] The 7-shaped holder 202 is symmetrically fixed at the top center of the bottom film 201. When two composite corrugated drainage pads 1 are connected, they are symmetrically placed on the top of the bottom film 201 with the 7-shaped holder 202 as the center.

[0029] The cone head block 204 is fixed at the bottom center of the top sheet 203, the top sheet 203 is pressed on the upper surface of the two composite corrugated drainage pads 1, and the cone head block 204 is clamped on the inner side of the two 7-shaped clamping seats 202 to realize the connection between the bottom sheet 201 and the top sheet 203, and the two composite corrugated drainage pads 1 are clamped and fixed by the bottom sheet 201 and the top sheet 203;

[0030] The reinforcement unit includes an elastic barbed hook 205, which is symmetrically fixed to the top of the bottom sheet 201 and the bottom of the top sheet 203 with the 7-shaped clamping seat 202 and the cone head clamping block 204 as the center;

[0031] The elastic barbed hooks 205 on the top of the bottom sheet 201 pierce the nonwoven geotextile 102 at the bottom, and the elastic barbed hooks 205 on the bottom of the top sheet 203 pierce the nonwoven geotextile 102 at the top. The elastic barbed hooks 205 piercing the nonwoven geotextile 102 can further increase the connection force between the nonwoven geotextile 102 and the bottom sheet 201 and the top sheet 203.

[0032] In this embodiment: when the composite corrugated drainage mat 1 is being paved, when the first section of the composite corrugated drainage mat 1 is almost paved, the bottom film 201 can be firstly laid horizontally on the ground (the paving direction of the composite corrugated drainage mat 1 is longitudinal), and then the end of the first section of the composite corrugated drainage mat 1 is overlapped on the top of the bottom film 201, and then the initial end of the second section of the composite corrugated drainage mat 1 is overlapped on the top of the other end of the bottom film 201, and the ends of the composite corrugated drainage mats 1 at both ends are symmetrically distributed with the 7-shaped holder 202 as the center. At this time, the composite corrugated drainage mat 1 can be stepped on, so that the elastic barbed hooks 205 on the top of the bottom film 201 pierce the geotextile 102 at the bottom;

[0033] Then, the top sheet 203 is laid on the top of the joint of the two sections of the composite corrugated drainage mat 1, with the cone head block 204 facing downward and located in the middle of the two 7-shaped holders 202. Then, the top of the top sheet 203 is stepped on, and the elastic barbed hooks 205 at the bottom of the top sheet 203 pierce the non-woven geotextile 102 at the top. At the same time, the cone head block 204 presses the two 7-shaped holders 202 downward, and the two 7-shaped holders 202 are deformed by force, so that the cone head block 204 is smoothly inserted into the two In the middle of the 7-shaped holder 202, the 7-shaped holder 202 will be reset under the action of its own elastic force, and then the 7-shaped holder 202 and the cone head block 204 will be clamped together. At this time, the top sheet 203 is connected to the bottom sheet 201, and the two sections of the composite corrugated drainage mat 1 are clamped in the middle, and then the two sections of the composite corrugated drainage mat 1 are spliced ​​and fixed. Compared with the traditional structure of directly overlapping the composite corrugated drainage mat 1, it can effectively avoid the offset phenomenon at the splicing point of the composite corrugated drainage mat 1.

[0034] Please refer to Figures 1 to 3 There are multiple 7-shaped card seats 202 and cone head blocks 204 evenly distributed along the tracks of the bottom film 201 and the top film 203. The length of the 7-shaped card seat 202 along the distribution direction is greater than the length of the cone head block 204, and the number of the cone head block 204 is greater than the number of the 7-shaped card seat 202.

[0035] In this embodiment: this structure allows the cone head block 204 and the 7-shaped socket 202 to be connected without precise alignment. During the splicing process, even if there is misalignment along the distribution direction, stable connection can be achieved, thus reducing the difficulty of construction.

[0036] Please refer to Figures 1 to 3 A bending portion is formed at the top of the elastic barbed hook 205, and the bending portion faces the 7-shaped holder 202 and the cone head block 204. The height of the bottom of the elastic barbed hook 205 from the bottom of the bending portion is greater than the thickness of the non-woven geotextile 102.

[0037] In this embodiment: after the elastic barb 205 pierces the non-woven geotextile 102, its bent portion also passes through the non-woven geotextile 102 simultaneously, so that the non-woven geotextile 102 is not easily separated from the elastic barb 205, thereby ensuring the connection stability of the composite corrugated drainage mat 1.

[0038] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
