Description

[0002] Impermeable membrane is widely applied in industrial solid waste storage and landfill, domestic waste landfill and water conservancy projects, and plays a role of barrier and impermeability. In existing construction, laying of impermeable membrane basically adopts manual rolling laying method. Since the geomembrane is heavy and bulky, usually, multiple persons need to cooperate. When laying a slope, the method of rolling down from the top of the slope by gravity, along the slope and freely is usually adopted. After the rolling down laying is completed, the laying of impermeable membrane is corrected. When laying a plane, the geomembrane is pushed by workers by bending over.

[0003] The existing worker laying method has the following problems:

[0004] (1) The free rolling laying of the slope cannot control the speed and direction of the rolling down of the impermeable membrane, which firstly causes the membrane to be pulled too tight, and the membrane is prone to deformation or longitudinal wrinkle caused by excessive tension. Moreover, the impermeable membrane rolls down along the slope by gravity, which may damage the flatness of the base. Secondly, deviation is prone to occur, and correction in the later stage not only consumes a lot of working time, but also the uneven tearing stress caused by manual dragging after the whole impermeable membrane is unfolded, which affects the impermeability of the membrane and further affects the overall construction quality.

[0005] (2) The worker bending over to push the membrane for laying cannot achieve balanced force, the membrane is prone to deviation, the laying is difficult, time-consuming and labor-consuming, and after the laying work is completed, the workers have lumbar pain, the overall working efficiency is low, the labor cost is high, and the personnel organization and management are difficult.

[0034] The application will be described in further detail below in conjunction with the drawings:

[0035] The first object of the application is a construction device for laying a permeation membrane, such as Figure 1As shown, including traction device 1, loading bracket 2 and mobile bracket 3; The traction device 1 and loading bracket 2 are connected; The loading bracket 2 and mobile bracket 3 are detachably connected; Traction device 1 provides power for the walking of the construction device of the utility model; The one end of the anti-seepage membrane is fixed on the loading bracket 2, and the other end is connected with the mobile bracket 3; After separating the mobile bracket 3 and the loading bracket 2, the mobile bracket 3 pulls one end of the anti-seepage membrane 4 to make the anti-seepage membrane 4 unfold and lay.

[0036] As Figure 2 And Figure 3 As shown, the loading bracket 2 is provided with a film containing cylinder 21, a film feeding mechanism 25 and a winch 23; The film containing cylinder 21 is provided with an anti-seepage membrane 4; The film feeding mechanism 25 is arranged at the outlet of the film containing cylinder 21; The winch 23 is arranged above the film feeding mechanism 25; The winch 23 is wound with a steel wire rope 5; The mobile bracket 3 is provided with a clamping device 33 and a tensioning mechanism 32; The clamping device 33 is connected with the anti-seepage membrane 4; The tensioning mechanism 32 is connected with the steel wire rope 5. The film containing cylinder 21 is used for containing the anti-seepage membrane 4, which can effectively protect the film material from the influence of external environment, such as preventing sunlight, rain or dust from damaging the film material. By setting the film containing cylinder 21, the film material can be conveniently stored and protected, and at the same time, storage space is provided for the unfolding of the anti-seepage membrane 4. The anti-seepage membrane 4 is used for preventing water or other liquid from penetrating, which can play a key role in the fields of civil engineering, water conservancy engineering, environmental protection, etc. The film feeding mechanism 25 smoothly sends the anti-seepage membrane 4 out of the film containing cylinder 21, ensures that the film is not wound or blocked during the unfolding process, provides smooth film feeding, avoids damage or distortion of the film material, and ensures smooth unfolding of the film. The winch 23 provides powerful power for controlling the winding and unwinding of the steel wire rope 5, adjusting the tension of the film, which can help to stretch and place the anti-seepage membrane 4, and can accurately adjust the position and state of the film through the steel wire rope 5, to ensure accurate laying of the film. The steel wire rope 5 ensures that the film material can be accurately and stably stretched, avoiding uneven tension or misplacement problems. The clamping device 33 can effectively fix the anti-seepage membrane 4, prevent it from shifting or wrinkling during stretching, and accurately maintain the positioning of the film during laying, avoiding the influence of loose film on laying effect. The tensioning mechanism 32 is a semicircular structure, which is used for adjusting the tension of the steel wire rope 5, ensuring that the anti-seepage membrane 4 can be pulled flat and uniformly, and by adjusting the tensioning force, the overstretching or relaxation of the film can be avoided, to ensure the laying quality of the film.

[0037] The frame of the film containing cylinder 21 is formed by welding the fixed rod, which ensures that the film containing cylinder 21 has sufficient stability and carrying capacity, avoiding deformation or damage during use. As Figure 4As shown, the bottom of the film containing cylinder 21 is sequentially and spacedly provided with a first auxiliary roller 211, a first rotating roller 212, a second auxiliary roller 213, a second rotating roller 214 and a third auxiliary roller 215; through the auxiliary roller and the rotating roller, the active free rolling of the impermeable film 4 can be realized, the conveying fluency of the film is improved, meanwhile, the deformation of the impermeable film 4 caused by excessive tension in local part is avoided, and the film deviation in the laying process is also avoided. The auxiliary roller and the rotating roller are fixedly connected through the first bearing seat 216 and the film containing cylinder 21, so that the overall structural stability of the system is enhanced, and the looseness or falling off of the roller assembly caused by vibration or impact is avoided.

[0041] The bottom outer side of the film feeding mechanism 25 is provided with a driving motor 253; the end of the lower pinch roller 251 is connected with the driving motor 253. Through adjusting the linkage device between the driving motor 253 and each roller, the synchronization of the film conveying amount of the film containing cylinder 21 and the film feeding mechanism 25 is ensured.

[0042] The loading support 2 is provided with a first pulling system 24; the moving support 3 is provided with a second pulling system 31; the first pulling system 24 and the second pulling system 31 are detachably connected.
