- Before pumping concrete, the water in the storage hopper is pumped out of the pipeline to achieve the purpose of wetting and cleaning pipes. And then added to the cement mortar and concrete mix proportion in the hopper (or 1:2 cement mortar), lubricating pipe can start pumping concrete; start pumping, pumping speed slow, hydraulic pressure in the acceptable range, to be pumping well, only with the normal speed of pump. Concrete pumping concrete for continuous operation, if not timely, need to reduce the pump speed, the pump is temporarily interrupted, don't stop stirring; pumping finished cleaning pipes, using air compressor driven cleaning ball, and then immediately wash the concrete pump and pipeline, pipeline disassembled according to different specifications of classification.s

How to calculate the lining formwork trolley in tunnel construction
- In the construction of the tunnel lining template can belong to the low value consumables in accounting, purchasing back into low value, and share in the future cost of 50%, scrap reamortization into 50% of the cost of this method is of low value consumables 55 amortization method; fixed assets, equipment car belonging to the class the asset depreciation period of 10 years. The lining template trolley for a device, rather than separate accounting, and the template should be turnover materials? Added: I engaged in casting model in the low value consumable, car is of course equipment assets added: template is a collar with the repeated use of the low value consumables, which belongs to the class of tools, you can also be classified as turnover materials, but according to the use of reasonable cost sharing principle after ask: you the manufacture of accounting, and it is in the tunnel construction, the construction enterprise to buy trolley. I personally feel that the template should be separated from the car accounting, so more true and accurate. Thank yous
