Technical Field

[0001] The utility model relates to the technical field of leakage detection, in particular to a buoyancy judgement device for vertical anti-seepage membrane installation detection, and in particular to a device for judging whether a locking connection between a front anti-seepage unit and a rear anti-seepage unit of the vertical anti-seepage membrane is disengaged. Background Art

[0002] Flexible vertical anti-seepage technology has gradually been applied in the field of environmental protection technology due to its high anti-seepage grade, strong durability and resistance to uneven settlement, and mature construction technology. It is specifically used in the fields of domestic waste landfill pollution control, mining and metallurgical pollution control, hazardous waste landfill pollution control, petrochemical pollution control, and contaminated site remediation.

[0003] During the construction of the vertical anti-seepage membrane, the first anti-seepage unit is first laid by means of a crane and other equipment, and the rear anti-seepage unit is laid after the first anti-seepage unit is in place; when laying the rear anti-seepage unit, the lock buckle on one side of the rear anti-seepage unit is matched with the lock buckle on the opposite side of the first anti-seepage unit; that is, after the lock buckle on one side of the rear anti-seepage unit is buckled into the lock buckle on the opposite side of the first anti-seepage unit, the rear anti-seepage unit is slid and installed from top to bottom to the designated position; the first anti-seepage unit and the rear anti-seepage unit include a frame and an anti-seepage geomembrane installed on the frame.

[0004] In terms of quality inspection of flexible vertical anti-seepage technology, Patent ZL201520669907.7 discloses a leakage detection system for vertical anti-seepage membranes. The system includes a potential collection device and a leakage monitoring device, which are electrically connected; the potential collection device is used to collect the potential on the surface of the vertical anti-seepage membrane; the leakage monitoring device is used to determine whether there is leakage in the vertical anti-seepage membrane based on the potential collected by the potential collection device. Although this patent can perform quality inspection on vertical anti-seepage membranes, the membrane body has been installed and even backfilled during detection, and the membrane body cannot be actively removed vertically, and can only be repaired passively.

[0005] The main problem of membrane leakage is not in the membrane itself, but mainly between the lock buckles. The assembly and docking of the lock buckles are below the mud liquid level, which is a hidden project. It is difficult to effectively judge whether it is installed in place during the process. Based on the above technical situation and technical difficulties, it is a problem that technicians in this field need to consider and overcome. Utility Model Content

[0008] As a further improvement of the utility model, the lock buckle between the socket part and the front width anti-seepage unit includes one of a slider lock buckle, a square interlocking buckle, an E-type porous buckle, a multi-stage sealing buckle, and a diamond interlocking buckle.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0022] The utility model provides a buoyancy judgement device for installation detection of a vertical anti-seepage membrane. During the construction of the vertical anti-seepage membrane, a first anti-seepage unit is first laid by means of a crane and other equipment, and then a rear anti-seepage unit is laid after the first anti-seepage unit is laid in place; when the rear anti-seepage unit is laid, a lock buckle on one side of the rear anti-seepage unit is matched with a lock buckle on the opposite side of the first anti-seepage unit; that is, after the lock buckle on one side of the rear anti-seepage unit is buckled into the lock buckle on the opposite side of the first anti-seepage unit, the rear anti-seepage unit is slid and installed from top to bottom to a designated position; the first anti-seepage unit and the rear anti-seepage unit include a frame and an anti-seepage geomembrane installed on the frame, and matching lock buckles are installed on two opposite vertical sides of the frame, and the lock buckles can be in the form of slider lock buckles, square interlocking buckles, E-type porous buckles, multi-stage sealing buckles, diamond interlocking buckles and other lock buckle forms. For example, when a slider lock is used, a slider is provided on one vertical side of the frame of the anti-seepage unit, and a slide rail matching the slider is provided on the other side; after the first width anti-seepage unit is laid, the slider of the rear width anti-seepage unit is slid into the slide rail entrance at the top of the first width anti-seepage unit, and the rear width anti-seepage unit is laid vertically from top to bottom under the action of the crane, and when the rear width anti-seepage unit is flush with the top of the first width anti-seepage unit, the laying of the rear width anti-seepage unit is completed. At the same time, sliding locks such as E-type porous buckles, multi-stage sealing buckles, and diamond-shaped interlocking buckles can also be used. It should be noted that the structure and laying method of the above-mentioned vertical anti-seepage membrane are existing conventional structures and laying methods, so further detailed elaboration thereof is omitted.

[0023] In order to prevent the rear anti-seepage unit from being disconnected from the front anti-seepage unit when it is laid, the utility model designs a buoyancy judgement device, such as Figure 1As shown, the buoyancy judgement device includes a socket part 1, a buoyancy part 2 and a connecting rope 3, and the socket part cooperates with the lock buckle of the front width anti-seepage unit. For example, when the lock buckle of the anti-seepage unit adopts a slider lock buckle, the socket part can adopt a slider that cooperates with the side slide rail of the front width anti-seepage unit; it should be noted that the slider of the buoyancy judgement device and the slider of the rear width anti-seepage unit are consistent with the side slide rail of the front width anti-seepage unit, but the sizes of the two are different. For example, the size of the slider of the buoyancy judgement device can be 10 to 30 cm, and the slider of the rear width anti-seepage unit can be selected in a larger size according to the size of the rear width anti-seepage unit. The size of the anti-seepage unit The height is usually several meters or tens of meters, and the height of the slider and the slide rail of the rear anti-seepage unit can be selected from 5 to 30 meters; based on this, after the first anti-seepage unit is laid, before the rear anti-seepage unit is laid, the slider of the buoyancy judgement device is first slid into the slide rail corresponding to the first anti-seepage unit, and then the slider of the rear anti-seepage unit is slid into the slide rail corresponding to the first anti-seepage unit, and the slider of the rear anti-seepage unit can push the slider of the buoyancy judgement device to move downward. When the rear anti-seepage unit is installed in place, that is, the rear anti-seepage unit is flush with the top of the first anti-seepage unit, the slider of the buoyancy judgement device is squeezed out of the slide rail by the slider of the rear anti-seepage unit. At this time, the buoyancy part 2 of the utility model is connected to the socket part 1 (such as a slider) through the connecting rope 3, and the buoyancy of the buoyancy part 2 is greater than the gravity of the socket part 1 in the mud; that is, when the slider of the buoyancy judgement device is squeezed out of the slide rail by the slider of the rear anti-seepage unit, it can be driven to float to the surface by the buoyancy part 2. At the same time, sliding locks such as E-type multi-hole buckles, multi-stage sealing buckles, and diamond-shaped interlocking buckles can also be used.

[0024] Furthermore, the shape of the buoyancy part is spherical or elliptical, 5cm≤equivalent diameter D≤20cm; 20cm≤connecting rope length L≤50cm.

[0025] The utility model can realize, through the structure of the buoyancy judgement device, that when the buoyancy judgement device floats above the mud surface when the rear anti-seepage unit is flush with the top of the front anti-seepage unit, it is judged that the flexible vertical anti-seepage lock buckle is installed in place; when the buoyancy judgement device floats above the mud surface during the installation of the rear anti-seepage unit, it is judged that the installation of the flexible vertical anti-seepage lock buckle fails.
