First, the introduction of cast-in-place lining machine

    CQ130-60 cast-in-place channel lining machine is our company engineering and technical personnel according to market needs, play mechanism of concrete molding technology research accumulated more than 40 years of successful experience, is simple construction, easy operation, high production efficiency, low labor intensity , The equipment structure is scientific and reasonable, full-featured, stable performance, high degree of automation for the target design and development of the leading areas of the new generation of channel lining machine. The use of CQ130-60 cast-in-place channel lining machine construction site pouring U-shaped, ladder, rectangular impermeable channel without the traditional construction method of the template investment and template installation removal and handling a large number of materials, can reduce construction costs by 50%.

Second, the drainage bed construction methods

1, in accordance with the slope to determine the slope of the bed and the height of the basis of stratified rolling, so that the soil density of not less than 1600Kg / m3;

2, set the channel centerline to the center line to both sides in accordance with the channel width of the release of both sides;

3, according to the size of the line and the slope of the slope than the excavation of the earth, not greater than the standard section, do not dig backfill, slightly less than the standard section is appropriate (the machine has a bed of bed repair function).

Third, the use of lining machine

1, in the shape of the channel along the bottom of the slope in accordance with the height of the slope and the lining of the laying wheel laying wheel guide rails;

2, check the lining of the various parts and screws are tightened, the lining machine laying a good guide rails, so that the lining of the guide mode, vibration mode and sliding mode and soil in the same center line;

3, connecting the wire rope and traction hook, and the rope rope pulley hook placed 30m at the top of the lining machine is fixed, put the wire rope, you must first put the clutch in a separate state, put the rope after the clutch back to the original position;

4, no load test: start the vibrator and hoist, in the case of no load to check whether the normal work of the machine, if no exception, can be prepared on the lining;

5, concrete mixing water-cement ratio to 0.44-0.48 is appropriate, aggregate particle size is not greater than the wall thickness of 1/4, gravel ratio is not greater than 44% of the stone, can add no more than 25% of cement content of coal Gray to improve the mobility of concrete, to promote the transaction, to achieve external light real. Specific according to the label and according to soil and weather and other factors;

6, lining, the filler to the silo of 2/3, the first open vibration, and then open the hoist to walk, while walking along the packing vibration, with the artificial face;

7, according to the channel level, every 4-6 meters set expansion joints together, in the lining after the concrete in the condensation before the use of portable cutting expansion joints;

8, on the shape of the concrete channel coating conservation.
