Description

Technical Field

[0001] The invention relates to the technical field of dam construction machinery, and in particular to a remote-controlled crawler equipment traction slope rolling construction method. Background Art

[0002] The rolling of the slope cushion material and slope fixing mortar of the concrete panel rockfill dam is a key link in the construction of the pumped storage power station. The construction quality directly affects the construction quality of the reservoir anti-seepage panel. At present, the commonly used rolling equipment includes rollers and vehicle-mounted rolling tractors. Single rollers are mostly used for rolling on the ground or on smaller slopes. The rolling of the rolling wheel is driven by the vehicle body. It has good effects in steering and rolling, but it is not suitable for slopes with larger slopes. The equipment commonly used on slopes is slope rolling equipment. The tractor is above the slope and uses a winch to drive the traction rope, which pulls the roller upward. The tractor using the slope rolling equipment cannot guarantee the rolling direction, is prone to deviation, and is difficult to control the steering of the roller. In the case of high panel rockfill dams, the entire construction process is more difficult to control, and slippage is prone to occur, which will greatly affect the construction quality and construction safety of the rolling of the slope cushion material.

[0003] In view of the above problems, a remote-controlled crawler equipment traction slope rolling construction technology is proposed, which effectively solves the shortcomings of traditional slope rolling, such as the rolling direction cannot be guaranteed, easy deviation, long construction time and difficult to control the stability of the construction process. At the same time, by setting pulleys and adjustable supporting platforms, the traction angle can be accurately adjusted and controlled, which greatly improves the construction efficiency and ensures the rolling quality. Summary of the invention

Investigate and check the topography, geology and structural conditions of the construction site, prepare construction materials and equipment, and then conduct on-site survey and layout of the construction site; S2. After the initial leveling of the slope, loosen the soil with a loosening machine, then sprinkle filler, and manually repair the locations with large fluctuations. The amplitude of convexity and concavity should be controlled within +5CM to -8CM; S3. After the slope of the cushion layer is trimmed, spray water to moisten the area that needs to be rolled. After drying for 4 hours, use remote-controlled crawler-driven slope rolling equipment to roll it. During rolling, it only vibrates when going uphill and does not vibrate when going downhill. Use the staggered distance method or overlap method. The two rollings should overlap, and the rolling tracks overlap by 5 to 10 cm. During the rolling process, the roller speed is controlled within 1.5 km / h, and the speed is controlled evenly; S4. After the cushion material slope is rolled and qualified, mortar slope protection construction is carried out. The mortar spreading thickness is maintained within 5CM-8CM. When the mortar is close to the initial setting time, the overlapping method is used to roll it twice.
