Circularly progressively rolling type channel lining machine

Abstract

The invention discloses a circularly progressively rolling type channel lining machine which comprises support rails, a rolling device and a framework. The circularly progressively rolling type channel lining machine is characterized in that two end transverse beams are connected with the two side support rails; slide transverse beams are slidably connected onto two side slide rails, and the framework is connected onto the slide transverse beams; a channel shaping bulldozing plate, a collecting hopper, a joint cutting device and the rolling device are sequentially assembled on the framework; the collecting hopper is provided with a front collecting hopper and a rear collecting hopper, a leaking opening is formed in the bottom of the front collecting hopper, and leaking openings are formed in two sides of the rear collecting hopper; side connecting plates and bottom connecting plates are connected onto the framework, side vibrating rollers are connected onto the side connecting plates, and bottom vibrating rollers are connected onto the bottom connecting plates; flexible transmission racks are wound on driving and driven gears, and a point of each flexible transmission rack is fixedly connected with the framework. The circularly progressively rolling type channel lining machine has the advantages that continuous channel lining construction can be carried out via rolling operation, so that the construction speed can be increased, and the channel concrete construction quality and the durability of a project can be improved; the circularly progressively rolling type channel lining machine is simple in operation, labor can be saved, the cost of the project can be lowered, and disruption and pollution to surrounding environments can be reduced.

Description

technical field [0001] The invention belongs to construction equipment for prefabricated concrete anti-seepage lining, in particular to a circular progressive rolling type channel lining machine. Background technique [0002] Due to the climate in northern my country, frost heave damages the precast concrete anti-seepage lining more obviously. Generally speaking, after two or three years of freeze-thaw cycles, the channels with precast concrete lining will leak a lot at the joints; Due to its thin thickness, generally 5-10cm, the anti-seepage of cast-in-place concrete is not easy to vibrate and compact, resulting in a decrease in the durability of the concrete and affecting the service life of the channel. [0003] At present, in the lining of small canals, the quality of the cast-in-place concrete lining is often not high because the vibration of the concrete is not easy to control during construction. More, it will also cause damage to the surrounding environment, which do...

Problems solved by technology

However, the traditional canal lining machine mainly adopts the principle of drawing die, and realizes the vibration and compaction of the lining concrete by the weight of the machine itself and the surface vibration, and the phenomenon of uneven density often occurs at the corners and the junction of the concrete and the soil layer. At the same time, the construction speed is affected by the initial setting time of concrete, so rapid construction cannot be achieved.
