AI Technical Summary
After geomembrane is laid, dust, sand, mud and other impurities easily adhere to its surface. Traditional construction methods are inefficient and difficult to completely remove these impurities, which can lead to them embedding into the joints during welding and forming leakage channels. Existing welding equipment has limited height adjustment and positioning functions, making it difficult to adapt to different terrains or membrane thicknesses. This can easily result in welding position deviation and uneven heat fusion, affecting the quality of the project.
The system uses three hydraulic cylinders to adjust the height of the support legs, one hydraulic cylinder to control the position of the dust collection box, and three hydraulic cylinders to control the height of the welding machine. The motor drives the fan blades to rotate and generate airflow to suck dust and impurities into the dust collection box. The combination of flexible support leg height adjustment and precise positioning of the welding machine ensures that the geomembrane surface is clean and adapts to different terrains.
It effectively prevents impurities from getting stuck at the membrane seams, improves welding strength, reduces the risk of leakage, ensures tight adhesion at the seams, and improves project quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction equipment technology, and in particular to a construction device for a large-area impermeable geomembrane. Background Technology
[0002] Geomembranes are widely used in seepage control projects such as water conservancy projects, landfills, and artificial lakes due to their excellent seepage control and durability. However, the welding quality of geomembranes directly affects the seepage control effect and service life of the project. Geomembrane welding construction generally faces two major technical challenges: First, the construction site environment is complex, and dust, sand, mud, and other impurities easily adhere to the surface of the geomembrane after laying. Traditional construction methods often rely on manual cleaning, which is not only inefficient but also difficult to thoroughly remove tiny particles, causing impurities to embed into the joints during welding and forming leakage channels. Second, existing welding equipment has limited height adjustment and positioning functions, making it difficult to adapt to different terrains or membrane thicknesses. This easily leads to problems such as welding position misalignment and uneven heat fusion, resulting in insufficient joint strength and seriously affecting project quality. Statistics show that leakage accidents caused by incomplete surface cleaning and low welding precision are relatively common. Summary of the Invention
[0003] The purpose of this invention is to solve at least one of the technical problems existing in the prior art by providing a large-area impermeable geomembrane construction device. This device addresses the challenges of complex construction site environments where dust, sand, and mud easily adhere to the surface of the geomembrane after laying. Traditional construction methods often rely on manual cleaning, which is not only inefficient but also fails to thoroughly remove tiny particles, leading to impurities embedding into the joints during welding and forming leakage channels. Furthermore, existing welding equipment has limited height adjustment and positioning functions, making it difficult to adapt to different terrains or membrane thicknesses, and prone to problems such as welding position misalignment and uneven heat fusion, resulting in insufficient joint strength and seriously affecting project quality. Statistics show that leakage accidents caused by incomplete surface cleaning and low welding precision are relatively common.
[0004] This utility model also provides a large-area impermeable geomembrane construction device, with the following advantages: The operator controls hydraulic cylinder three to adjust the height of the support legs, then controls hydraulic cylinder one to control the position of the dust collection box, and then controls hydraulic cylinder three to control the height of the welding machine. This pushes the flatbed cart to start the motor. The motor drives the fan blades to rotate, generating air that draws dust and impurities from the surface of the geomembrane onto the ground into the dust collection box. The welding machine then welds the geomembrane. This process draws dust and impurities from the geomembrane surface into the dust collection box, preventing impurities from getting stuck at the joints and avoiding residual sand or mud on the geomembrane surface, which could create gaps during welding and increase the risk of leakage. After dust collection, the joints are tightly sealed, resulting in higher welding strength and effectively reducing the probability of soil seepage at the joints.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0016] Reference Figure 1-4 This utility model embodiment discloses a large-area impermeable geomembrane construction device, which includes: a fixed plate 2, a hydraulic cylinder 1 fixedly connected to the upper surface of the fixed plate 2, the output end of the hydraulic cylinder 1 extending to the lower surface of the fixed plate 2, a hydraulic push rod 12 fixedly connected to the output end of the hydraulic cylinder 1, a dust collection box 14 fixedly connected to the other end of the hydraulic push rod 12, an air inlet pipe 13 connected to the side surface of the dust collection box 14, a bracket 19 fixedly connected to the inner wall of the air inlet pipe 13, a fan blade 18 rotatably connected to the inner surface of the bracket 19, an air collector 9 fixedly connected to the other end of the air inlet pipe 13, the air collector 9 being made of stainless steel, a motor 20 fixedly connected to the outer surface of the bracket 19, the fan blade 18 being driven by the motor 20, and the hydraulic cylinder 1 and the hydraulic cylinder 2 11 being symmetrically designed, with the hydraulic cylinder 1 located at the front end of the hydraulic cylinder 2 11.
[0017] Specifically: Hydraulic cylinder 1 drives hydraulic push rod 12 to adjust the position of dust collection box 14. Motor 20 drives fan blade 18 to rotate. The resulting airflow draws dust and impurities from the surface of the geomembrane on the ground into the dust collection box 14. This prevents impurities from getting stuck at the joints of the geomembrane and avoids residual sand or mud on the surface of the geomembrane, which could lead to gaps during welding and leakage. After dust collection, the joints are tightly sealed, the welding strength is higher, and the probability of soil seepage at the joints is effectively reduced.
[0018] The dust collection box 14 is equipped with a door 16, and a handle 15 is provided on the door 16. The door 16 is opposite to the air inlet pipe 13.

[0019] Specifically: Welding machine 10 is an existing device, mainly composed of a welding body, a heating device, a pressurizing mechanism, and traveling wheels. The heating device is usually of the hot wedge type or the hot air type. The former heats the membrane material through a wedge-shaped heating plate, while the latter uses a hot air gun for heating. The pressurizing mechanism is composed of cylinders or springs, and the traveling wheels facilitate the movement of the equipment. During operation, the operator needs to set the heating temperature and traveling speed in advance. After the heating device reaches the temperature, the operator pushes the equipment to heat and soften the membrane material. The pressurizing mechanism then presses it down, and welding is completed while the equipment is in motion. The handle 15 allows the operator to open the box door 16 to clean the inside of the dust collection box 14. Welding machine 10 welds geomembranes. The hydraulic cylinder 2 11 and hydraulic push rod 2 17 can adjust the height according to the geomembrane thickness.

A hydraulic push rod 3 4 is fixedly connected to the output end of the hydraulic cylinder 3 5. A rotating shaft 6 is rotatably connected to the lower surface of the support leg 3. A frame 7 is fixedly connected to the side surface of the rotating shaft 6. A roller 8 is rotatably connected to the inner surface of the frame 7. The roller 8 is provided with anti-slip patterns.
[0021] Specifically: the operator can adjust the height of the support leg by manipulating hydraulic cylinder 35, and the rotating shaft 6 can flexibly control the running direction of the flatbed truck.
[0022] Working principle: Hydraulic cylinder 1 drives hydraulic push rod 12 to adjust the position of dust collection box 14. Motor 20 drives fan blade 18 to rotate. The resulting airflow draws dust and impurities from the surface of the geomembrane on the ground into the dust collection box 14. This prevents impurities from getting stuck at the joints of the geomembrane and avoids residual sand or mud on the surface of the geomembrane, which could lead to gaps during welding and leakage. After dust collection, the joints are tightly sealed, the welding strength is higher, and the probability of soil seepage at the joints is effectively reduced.
