[0025] Technical effects and advantages of the present invention:

[0026] 1. The core component of the construction structure of the present invention is the extrusion trolley, which is made of galvanized steel. The components are simple to process, easy to install and have good practicality. During the implementation of this process, the traction power comes from the winch on the dam top, the power for extrusion is provided by the hydraulic device, and the water-stop material is manually assisted into the groove, which can form an integrated and orderly operation.

[0027] 2. Compared with the traditional processes of manual kneading or mechanical pressing of water-stopping materials, the construction of plastic water-stopping on the surface of dam panels by this process has the characteristics of high construction efficiency and good molding quality.

This process is suitable for the surface water-stopping construction of rockfill dam panels in water conservancy and hydropower projects and has broad prospects for promotion and application.

[0028] 3. The stainless steel material of the lifting ring can effectively prevent water erosion and extend its service life. Its rough surface structure can effectively make the connection between the wire rope and it more stable and reliable, making the synchronization between the two higher, thereby avoiding the deformation of the rope ladder caused by connection slippage at the connection and excessive vibration caused by vehicle inertia, thereby improving the safety of the overall device and the effect of long service life.

[0029] 4. By utilizing the design of the discharge port, the wind pressure on both sides can be blocked by the correction component when the plastic water-stop material is injected and poured, and the wind on both sides can be blocked by the guide plate. The structure with low sides and high middle can make the oblique wind pass through the guide groove and become a straight wind flow, so that the plastic water-stop material will only be affected by the front and rear wind forces, and will not fall outside the groove due to the oblique wind, thereby ensuring that it can be poured vertically downward during casting to prevent it from falling on both sides of the groove and causing material waste. The switch component is used to turn on the drive motor to drive the outer gear ring to rotate, so that the inner gear ring rotates at the same time, and cooperates with the passive gear to rotate the block and disengage from the baffle surface, so that the entire discharge port is in a connected state, thereby determining its flow and non-flow state, thereby further improving the utilization and casting efficiency of the plastic water-stop and improving the environmental friendliness of the overall device.

[0051] S8. The extrusion trolley extrudes materials while slowly rising by the winch 1 to form a continuous operation.

[0052] Working principle of the present invention:

[0053] The core component of the construction structure of the present invention is the extrusion trolley, which is made of galvanized steel. The various components are simple to process, easy to install, and have good practicality. During the implementation of this process, the traction power comes from the winch 1 on the dam top, the power for extrusion is provided by an electric hydraulic device, and the water-stop material is manually assisted into the groove, which can form an integrated and orderly operation.

[0054] The construction of plastic waterstopping on the surface of the dam panel through this process has the characteristics of high construction efficiency and good molding quality compared with traditional processes such as manual kneading or mechanical pressing of waterstop materials. It also saves the labor of transporting materials and ensures the construction quality of surface waterstopping. This process is suitable for the surface waterstop construction of rockfill dam panels in water conservancy and hydropower projects, and has broad prospects for promotion and application.

[0055] During the implementation of this process, by utilizing 4-4, when the plastic water-stop material is being injected and poured, the correction component 4-4-6 can be used to block the wind pressure on both sides, and the wind on both sides can be blocked by the guide plate 4-4-62. Moreover, through its low sides and high middle structure, the oblique wind can be turned into a straight wind flow through the guide groove 4-4-63, so that the plastic water-stop material will only be affected by the front and rear wind forces, and will not fall outside the groove due to the oblique wind, thereby ensuring that it can be poured vertically downward during casting to prevent it from falling.
