Description

Technical Field

[0001] The utility model relates to the technical field of pollutant barrier, in particular to a flexible barrier-assisted film recyclable counterweight device. Background Technique

[0002] The barrier technology is an important means for the risk control of contaminated sites. It mainly refers to the technology of laying a barrier layer to block the migration and diffusion path of pollutants in the soil medium, isolating the contaminated medium from the surrounding environment, and avoiding the harm to the human body and the surrounding environment caused by the contact between pollutants and the human body and the migration of pollutants with precipitation or groundwater. In the construction of flexible barriers, counterweight assistance is required for film laying. Conventional counterweights have certain limitations, and auxiliary equipment needs to be developed for barrier construction.

[0003] During the construction process of flexible barriers (HDPE films), the conventional counterweight construction is to hang precast concrete counterweight blocks at the bottom of the HDPE film, lift them to the section where flexible barrier construction is to be carried out, align the connecting lock with the previous HDPE film for connection, and then lower the HDPE film to the target depth to complete the construction of one flexible barrier film.

[0004] The conventional counterweight construction method is applicable to construction sites with relatively shallow barrier depths and small HDPE film widths. However, when encountering the construction of flexible barriers (HDPE films) with ultra-deep depths, using conventional counterweights for construction has obvious limitations. For example:

[0005] (1) It is difficult to control the lowering speed of the HDPE film, and its speed does not match well with the speed of the operator installing the expansion water stop strip, resulting in low construction efficiency;

[0006] (2) The prior art arranges several precast concrete counterweight blocks evenly at the lower end of the HDPE film. The HDPE film is prone to curl in the width direction, affecting the finished product quality and causing waste of raw materials;

[0007] (3) When using precast concrete counterweight blocks for barrier construction with relatively deep depths, as the film-laying depth becomes deeper and deeper, the deeper the depth, the longer the contact length between the connecting locks of the two films. At this time, due to insufficient counterweight quality, its gravity is less than the friction force between the connecting locks, resulting in jamming during the lowering process of the HDPE film and causing rework, affecting the construction progress;

[0008] (4) The precast concrete counterweight is a one-time counterweight, and a large number of concrete counterweights need to be prepared in advance, wasting materials.

[0009] With the development of the risk control depth of each contaminated site risk control project towards deeper directions, new challenges have been posed to the flexible barrier construction technology. Therefore, it is necessary to further study a flexible barrier (HDPE film)-assisted film-laying recyclable counterweight device that can meet the requirements of large construction depth, high speed, reusable, strong adaptability, good effect, and simple operation. Utility Model Content

[0010] In order to solve the problems existing in the construction of the above-mentioned flexible barrier, the utility model designs a flexible barrier auxiliary lower membrane recyclable weight device, which has a simple structure and can adapt to the construction requirements of flexible barrier lower membranes of different depths. The specific technical scheme is as follows:

[0011] A flexible barrier-assisted lower membrane recyclable counterweight device comprises a recyclable counterweight steel plate, a hanging point is arranged on the top of the recyclable counterweight steel plate, a channel steel section is arranged on the bottom of the recyclable counterweight steel plate, the recyclable counterweight steel plate is connected to a receiving mechanism through the channel steel section, and the receiving mechanism is fixedly connected to the HDPE membrane.

[0012] Preferably, the receiving mechanism includes connecting locks symmetrically arranged on both sides of the HDPE film, the connecting locks and the bottom connecting clamps of the HDPE film, and the clamps are connected to the bent steel bars.

[0013] Furthermore, the bent steel bar is L-shaped, and the horizontal section of the bent steel bar is connected to the clamping plate.

[0014] Furthermore, both ends of the channel steel section are connected to the recyclable counterweight steel plate to form square through holes corresponding to the bent steel bars.

[0015] Furthermore, the connecting lock includes a rubber plate, one side of the rubber plate is provided with a welding portion connected to the HDPE film, and the other side is connected with a plurality of T-shaped bars at equal intervals, and slots are formed between the T-shaped bars. The T-shaped bars are arranged on the opposite side of the HDPE film.

[0016] Preferably, the hanging points are symmetrically arranged on the top of the recyclable counterweight steel plate.

[0017] Preferably, the channel steel sections are arranged at equal intervals at the bottom of the recyclable counterweight steel plate.

[0018] Preferably, the channel steel section is welded to the recyclable counterweight steel plate.

[0031] The receiving mechanism includes connection lock catches 5 symmetrically welded to both sides of the HDPE film 4. The connection lock catches 5 include rubber plates 13. One side of the rubber plate 13 is provided with a welding part 12 connected to the HDPE film 4, and the other side is connected with a plurality of T-shaped bars 10 at equal intervals. A card slot 11 is formed between the T-shaped bars 10. The T-shaped bars 10 are arranged on the opposite sides of the HDPE film 4, and the welding part 12 is hot melt welded to the HDPE film 4. The bottom of the connection lock catches 5 and the HDPE film 4 are connected by clamping plates 6. The clamping plates 6 are flat steel bars with the same width as the HDPE film 4. The clamping plates 6 are fixed to the connection lock catches 5 and the HDPE film 4 through bolts. The clamping plates 6 are welded with bent-up steel bars 7. The bent-up steel bars 7 are L-shaped, and the horizontal sections of the bent-up steel bars 7 are connected to the clamping plates 6. Both ends of the channel steel section 3 are connected to the recyclable counterweight steel plate 1 to form a square through hole corresponding to the bent-up steel bar 7. The intervals between the bent-up steel bars 7 are the same as the intervals between the channel steel sections 3, which are used to dock the recyclable counterweight steel plate 1.

[0032] Working principle: Before the construction starts, the welding parts 12 of the connection lock catches 5 are symmetrically welded to both sides of the HDPE film 4. The lifting points 2 are hoisted by steel wires 8, and the upper ends of the steel wires 8 are connected to the hoisting equipment. The HDPE film 4 is wound on a film winding device.
