Description

Technical Field

[0001] The utility model relates to the technical field of slope consolidation mortar construction, in particular to a slipform device for slope consolidation mortar of a dam. Background Art

[0002] The upstream slope and protective layer of the cushion material of the concrete face rockfill dam are the foundation of the face plate and should be dense, flat and uniform. Especially for high dams and extra-high dams, the dam body has large deformation, so the protective layer is required to be basically flexible and able to coordinate deformation with the dam body. There should be no gaps between the cushion material and no protrusions.

[0003] At present, the upstream slope protection of the cushion material often adopts slope rolling mortar to consolidate the slope, but this method has the following disadvantages during construction: the mortar thickness is uneven and the rigidity is large. It cannot settle with the cushion material and is easy to cause voids. It is difficult for the slope to meet the "+5cm, -8cm" standard required by the specification, resulting in a large amount of overfilling of the panel concrete. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a slipform device for mortar for slope consolidation of a dam, a slipform trolley, a plastering trolley and a manual hoist for connecting the two. The vibration effect is improved by arranging a flat vibrator on the slipform trolley, and the flatness of the warehouse surface is improved by plastering the trolley again, which effectively avoids the phenomenon that the protective layer is hollowed out due to the super-strong and large rigidity of the slope consolidation mortar, and is beneficial to the safety of the panel structure.

[0005] A slipform device for mortar for slope consolidation of a dam comprises a slipform trolley, which comprises a first trolley base, a first operating platform and a first support seat.

[0006] A further technical solution is: the bottom mold is made of a steel plate with a thickness of 2 mm, and a plurality of holes for installing a flat plate vibrator are arranged on the bottom mold.

[0007] A further technical solution is: an upturned portion is provided at the front end of the bottom mold, the slope of the upturned portion is set to 1:5, and the height of the upturned portion is set to 5 to 7 cm.

[0008] A further technical solution is: the first operating platform is arranged parallel to the ground, the first support seat is arranged perpendicular to the ground, and the first operating platform, the first support seat and the first trolley base are interconnected to form a sliding mold trolley with a right-angled triangle cross-section.

[0009] A further technical solution is: the first operating platform includes a rectangular outer frame formed by welding 8# angle steel, and multiple support rods welded in the outer frame at equal intervals. The support rods are made of multiple 5# angle steels, and multiple operating table panels are laid on the top of the support rods.

[0010] A further technical solution is: a first handrail is fixedly connected to the top of the first support seat, and the first handrail is made of a steel pipe with a size of Ф48.3mm×3.5mm to form a grid-like railing.

The second trolley base is arranged parallel to the slope, the second operating platform is arranged parallel to the ground, the second support base is arranged perpendicular to the ground, and the second operating platform, the second support base and the second trolley base are interconnected to form a plastering trolley with a right-angled triangle cross-section.

[0012] Beneficial effects of the utility model:

[0013] The utility model discloses a slipform device for mortar for slope consolidation of a dam. The slipform trolley is used for vibrating the mortar and performing simple initial plastering, and the plastering trolley is used for secondary plastering to make the mortar surface smoother and ensure that the flatness of the mortar surface meets the specification requirements. The plastering trolley and the slipform trolley are connected as a whole by a manual hoist, and sliding is achieved through a winch system on the top of the dam. The utility model can effectively avoid the phenomenon of hollowing out of the protective layer due to excessive strength and high rigidity of the slope consolidation mortar, reduce constraints on the panel, facilitate anti-cracking of the panel, have a strong ability to adapt to deformation of the dam body, and facilitate the safety of the panel structure.

[0014] By arranging a bottom form at the bottom of the slipform trolley and arranging multiple flat plate vibrators on the bottom form, the vibration range of the flat plate vibrator radiates to the width of the construction warehouse surface, and the air is discharged through the vibration of the flat plate vibrator to ensure that the mortar on the entire warehouse surface is sufficiently vibrated, which can effectively avoid the phenomenon of vibration leakage; by arranging an upturned part at the front end of the bottom form, it can adapt to the virtual laying height of the mortar within 3 to 5 cm; by arranging a first operating platform on the top of the slipform trolley, it is convenient for personnel to construct and place corresponding equipment.

[0015] The distance between the slipform trolley and the plastering trolley is set to be adjustable through a manual hoist, which can be flexibly adjusted according to the temperature changes during construction. When the temperature at the construction site is high, the distance between the slipform trolley and the plastering trolley can be shortened; when the temperature at the construction site is relatively low, the distance between the slipform trolley and the plastering trolley can be increased to find the best plastering period and achieve the ideal plastering effect. The unevenness of the slope surface can be controlled within "+5cm~-8cm" to meet the requirements of the specifications. BRIEF DESCRIPTION OF THE DRAWINGS
