[0023] Appendix Figure 2 A schematic diagram of the zipper-type connector (female) provided in this embodiment;

[0024] Appendix Figure 3 The installation diagram of the zipper-type connector provided in this embodiment. Detailed Implementation

[0025] The zipper-type overlap connector provided in this embodiment, applicable to vertical HDPE membrane construction in the field of soil remediation, includes, for example: Figure 1 The zipper-type connector (male) shown and as... Figure 2 The zipper-style connector shown is female.

[0026] Among them, such as Figure 1 As shown, the zipper-type connector (male) 100 has a cuboid or similar geometric shape. A first auxiliary power guide wheel 131 and a second auxiliary power guide wheel 132 are symmetrically mounted on the upper and lower sides of its central part.

[0027] In this embodiment, the first auxiliary power guide wheel 131 and the second auxiliary power guide wheel 132 are designed as a three-wheel design. The arrangement position and number of the guide wheels can be adjusted according to the actual size of the connector and the needs of the application.

[0028] The zipper-type connector (male) 100 is equipped with a heating (welding) plate system 120 near one end, which heats and melts the two films on the left and right sides together by thermoplastic process during use.

[0029] The other end of the zipper-type connector (male) 100 is fitted with a retractable connecting bracket 110, such as Figure 3 As shown, in use, the retractable connecting bracket 110 is a protruding shape in the zipper-type connector (male) 100.

[0030] The corner of the zipper-type connector (male) 100 has a first push-out key 141, a second push-out key 142, a third push-out key 143, and a fourth push-out key 144. During use, the male and female connectors are separated by pushing the four push-out keys outward, thereby enabling equipment recycling.

[0031] like Figure 2 As shown, the female zipper connector 200 has a cuboid or similar geometric shape, which matches the male zipper connector 100. A first auxiliary power guide wheel 231 and a second auxiliary power guide wheel 232 are symmetrically mounted on the upper and lower sides of its central part.

[0032] In this embodiment, the first auxiliary power guide wheel 231 and the second auxiliary power guide wheel 232 are designed as a three-wheel design. The arrangement position and number of the guide wheels can be adjusted according to the actual size of the connector and the needs of the application.

[0033] Furthermore, during use, after the zipper-type connector (male) 100 and the zipper-type connector (female) 200 are assembled together, the first auxiliary power guide wheel 231 and the second auxiliary power guide wheel 132 are arranged opposite each other, located above and below the membrane body, respectively. Similarly, the second auxiliary power guide wheel 232 and the first auxiliary power guide wheel 131 are arranged opposite each other, located above and below the membrane body, respectively.

[0034] Of course, depending on the actual needs of use, the first auxiliary power guide wheel 231 and the second auxiliary power guide wheel 132, and the second auxiliary power guide wheel 232 and the first auxiliary power guide wheel 131 can also be staggered to achieve a conveyor belt-like effect on the upper and lower sides of the membrane.

[0035] The zipper type lap jointer (female) 200 is provided with a heating (welding) piece system 220 near one end, which is arranged opposite to the heating (welding) piece system 120, i.e. on the upper and lower sides of the film body, so that uniform heating of the upper and lower pressing states can be achieved during thermoplastic, and better hot melting results are achieved.

[0036] The other end of the zipper type lap jointer (female) 200 is provided with a retractable connecting bracket 210, as shown in the figure. Figure 3 As shown, in the use state, the retractable connecting bracket 210 is in the shape of a spring in the zipper type lap jointer (male) 100, i.e. when the protruding retractable connecting bracket 110 is pressed into the retractable connecting bracket 210 by external force, the effect of engaging with the retractable connecting bracket 210 can be achieved. In addition, according to the actual use needs, the assembly structure of the male and female lap jointers can also be the commonly used assembly schemes such as the lock catch structure, the magnetic attraction structure, and the spring structure.

[0037] The corner of the zipper type lap jointer (female) 200 has a first push-out key 241, a second push-out key 242, a third push-out key 243, and a fourth push-out key 244. In the use process, i.e. after the zipper type lap jointer (male) 100 and the zipper type lap jointer (female) 200 are assembled with each other, the first push-out key 241 is arranged opposite to the second push-out key 142, the second push-out key 242 is arranged opposite to the first push-out key 141, the third push-out key 243 is arranged opposite to the fourth push-out key 141, and the fourth push-out key 244 is arranged opposite to the third push-out key 143. When the hot melting is completed, the male and female lap jointers are separated from each other by pushing the push-out keys on the upper and lower sides outward, so that the equipment recycling is realized.

[0038] The push-out key can be mechanically pushed out / popped out or realized by electric control.

[0039] In addition, the shell of the zipper type lap jointer (male) 100 and the zipper type lap jointer (female) 200 is provided with a blowing system, and the wind force can be sent to the specified position through the ventilation slot on the outer viewing surface of the shell.

[0040] The specific use process is as follows:

[0041] (1) The film is placed under the groove bottom.

[0042] (2) As shown in the figure, install the two side films into the aligner (for example: the films are aligned with the zippers), as shown in the figure. Figure 3

[0043] (3) Open the power guide wheel system (blowing system).​

[0044] (4) Turn on the heating welder to heat and melt the two films together, and then lower the bottom of the slot to repeat the heating process.

[0045] (5) After the construction is completed to the bottom of the slot, turn off the heating welder system (underwater blowing system) and turn on the fixer connection system, and pull out the key to separate the two fixers and pull them back for recycling.
