Description
Technical Field
The invention relates to equipment suitable for filling surfaces, in particular to a bulldozer suitable for filling surfaces and a multipurpose rolling device thereof.
Background
In Atjiang county, sichuan Cumin Tibetan autonomous state, sichuan province at two estuary hydropower stations, the water retaining building is a gravel soil core wall rock-fill dam with a maximum dam height of 295 m, the core wall seepage-proofing body filling material is gravel soil material, and the filling amount is about 441 ten thousand m 3 . The gravel soil material is prepared by mixing soil material and gravel according to the proportion of 6:4 or 7:3, and the maximum grain diameter is not more than 150mm. The water content of the gravel soil material full filling should be W op -1.5％≤W≤W op In the +2.5% range, W op Is the optimal water content.
The core wall gravel soil material filling has short effective construction time, high strength, compact construction period and high quality standard. According to the statistics of the actual measurement data of the weather station in Athens county in past year, the average precipitation amount for years is 746.1mm, the precipitation amount in the rainy season (5-10 months) is 694.2mm, the precipitation amount is 93.0% of the whole year, and the maximum precipitation amount in one day of the past year is 70.6mm.
When the core wall gravel soil material is constructed in rainy seasons, the water content of the gravel soil can greatly exceed the required range, the construction must be suspended, the water content is regulated to be within the required range, and the construction can be resumed.
At present, in the domestic and foreign water conservancy and hydropower industry, earth and rockfill dam engineering (such as a long-dam hydropower station, a lozage hydropower station and the like) is conventionally adopted in rainy season construction: (1) pressing the core wall into a smooth surface by flat grinding before rain, and then covering with waterproof cloth; (2) the filling surface of the core wall soil material is made into a tortoiseshell shape (the middle part is slightly higher and the two sides are slightly lower), and the filling surface is rapidly pressed into a smooth surface by flat grinding before rain so as to be beneficial to drainage. The mountain canyon at the two estuary hydropower stations belongs to the climate zone of the Sichuan plateau, the sudden rainfall in the small mountain area and the like, the regional weather forecast has weak guidance, the rainfall time cannot be accurately predicted, the rain-proof cloth cannot be covered in time, and the water content of local soil materials is higher once the rain-proof cloth is covered and is not lapped in place; the filling surface of the core wall soil material is made into a tortoiseshell shape, and is quickly pressed into a smooth surface by flat grinding before rain, so that drainage is facilitated, but in actual construction, the filling surface still has a low-lying water accumulation position, so that local water is not uniform, and the reworking treatment time after rain is long.
In order to solve the problem, a device which can roll into a groove at one time after the filling surface of the core wall soil material is made into a tortoiseshell shape (with slightly higher middle and slightly lower two sides) in rainy season is needed to facilitate drainage.
