The machine comprises a feeding part, a traveling and lifting part, a distributing part and a vibration forming part, wherein the feeding part consists of a feeding belt machine which is distributed in the running direction of a channel shoulder, the traveling and lifting part consists of guide rails, traveling wheel groups, wheel boxes, transmission gears, motors, hydraulic fluid cylinder piston rods and support beams, the guide rails are paved in the running directions of the channel shoulder and the channel bottom, the traveling wheel groups are arranged on the rails, the wheel boxes are coated outside the wheel groups, the transmission gears are engaged with the wheel groups, the motors are linked with gear shafts, the hydraulic fluid cylinder piston rods are connected with the wheel boxes, the support beams are connected with a cylinder tube, the distributing part consists of a delivery belt machine, a distributing vehicle, an operation room and a material bin, the distributing vehicle and the operation room are arranged on a machine frame, the material bin is connected with one side of the machine frame, the two ends of the machine frame are respectively connected with the support beams, the vibration forming part consists of an inner vibration beam and an outer vibration beam, the inner vibration beam and the outer vibration beam are connected to the interior of the cavity and the outside of the machine frame of the delivery belt machine, the machine frame is sequentially provided with a spring seat, a connecting rope and the vibration beams from top to bottom, and the upper end surfaces of the two vibration beams are respectively provided with a vibration motor. The machine has the advantages that multiple operations, such as feeding, distributing, spreading and leveling, and compaction forming, are integrated, the flatness is higher, and the compactness is good.

Description

technical field [0001] The large-scale channel side slope cushion layer paving machine of the present invention belongs to the field of water conservancy engineering machinery. Background technique [0002] At present, the construction of large-scale channels adopts the construction method of paving the slope cushion material first, then laying the anti-seepage membrane on it, paving the lining concrete mechanically on the membrane, and finally cutting the structural joints by machinery. The slope cushion Layer materials are generally paved manually, by loaders or by dump trucks. After paving, vibrating rollers, vibrating plates or vibrating rammers are used to vibrate and compact. Repeated operations on the ground often lead to the destruction of the cushion surface structure, and due to the small construction area of ​​the vibration facilities, the uniformity of the cushion material density is poor, the cushion surface flatness is poor, the work efficiency is low, and the ...

AI Technical Summary

Problems solved by technology

[0005] ① High cost and imperfect functions

It needs to be equipped with an advanced and reliable imported automatic guidance and automatic alignment system of 1.2 to 1.5 million yuan, otherwise it will not work, and it will be powerless for the vibration of the cemented sand and gravel layer;

[0006] ② High requirements for construction conditions and poor adaptability

Concrete transport trucks must be used to feed materials at the bottom of the canal, and special feeding equipment is required, which is often limited by the width of the canal bottom, construction roads, groundwater levels, lining structures, and the impact of damage to the canal bottom foundation by concrete transport vehicles. use

[0007] ③The structure of the host is complex, and the cloth effect is poor

It is designed for laying flow plastic concrete from bottom to top, which is unreasonable, which makes the structure of the main engine complex, the power is large, the distribution is not timely and uneven, and the concrete is easily separated, so that the lining function of the main engine is limited.

[0008] The latter four are all fed by belt conveyors, and are set on the horizontal auger of the forming vehicle for material distribution. The forming vehicle moves up and down the slope to pave and pour concrete in a single width. Unguaranteed and low work efficiency

[0009] The above five types of lining machines, pouring machines, automatic paving equipment, and masonry machines are only suitable for pouring concrete with a thickness of ≤0.10m. Concrete with a certain degree of fluidity cannot be paved with dry and hard coarse sand, gravel mixture, cement modified soil, other modified soil, and dry hard mortar.
