Q:CFG pile base can use tamper tamp it: 2. Basic principles:The cohesive strength pile is the representative of composite foundation, and is used in high-rise buildings and super high-rise buildings. CFG pile is the abbreviation of cement fly ash gravel pile (cement, fIying-ash, gravel, pile). It is made of cement, fly ash, gravel and sand with water of high bond strength pile formed by mixing together, to form a composite foundation and pile and cushion. CFG pile composite foundation cushion and connected by the foundation, whether pile general fell hard soil or soil, can ensure the soil between piles has always been involved in work. Because the strength and modulus of the pile is larger than the soil between the piles, the stress at the top of the pile is greater than that on the soil under the action of the load. The pile can transfer the load to the deeper soil layer and reduce the load that the soil between the piles bear. Thus, because of the action of the pile, the bearing capacity of the composite foundation is increased, the deformation is reduced, and the CFG pile is not suitable for reinforcing bars, and the industrial waste material and the fly ash are used as admixture, thereby greatly reducing the project cost.The design of composite foundation, cushion thickness is arranged between the base and the pile and soil is composed of loose granular material, is a core technology of composite foundation. The foundation is set cushion, a great impact on the bearing capacity of composite foundation. If there are no cushion, loading behavior of the composite foundation and pile foundation is similar to that of soil between piles bearing capacity of composite foundation can be difficult to play. Under the foundation of cushion, settlement of bearing capacity of soil between piles play not only depends on the pile, the pile end even fell on good soil, but also to ensure the load to the soil between piles with cushion layer, the soil pile to bear load.

Q:Principle and application of rammer: Ramming machine power rammerCompaction machine for tamping compacted backfill soil by impact and impact vibration. Sub fire rammer, breaststroke tamping rammer and etc..Thermal rammerAccording to the principle of two stroke internal combustion engine, there are two upper and lower pistons in the cylinder. The upper piston is an internal combustion piston, and the lower piston is a buffer piston. The lower part of the cylinder is fitted with a rammer with an inclined bottom to deflect the vertical axis of the cylinder toward the front. The piston rod from the through hole of the cylinder cover in the middle reach of piston rod from the lower end of the cylinder and hammer out and integrated between cylinder and hammer with spring tension, direction and a handrail is arranged to control the rammer. The fire is rammed under the action of the explosive force of the combustible mixture, so it jumps off the ground from the top to the top, and then hits the ground and strikes the soil under the weight of itself. The hammer falls and the body moves forward step by step.

Q:Ramming machine excavator and compacted soil which good?: Digging machine for large area. The wall corner place for breaststroke.

Q:Gasoline rammer return pipe leakage is going on: This problem is not recommended to repair and repair, repair and repair once hundreds to thousands or even tens of thousands. But it may not solve the problem, but also hurt the car. It is recommended that the majority of car owners use the "free repair and repair" method to solve the problem of automobile oil leakage.

Q:Can drive the ramming machine need many kilowatts generator: To see how much power rammer motor generator to you, two times larger than the above power rammer.

Q:Wire, you can run. Why don't you take the center line?: In addition to the power system 380/220 power supply system with zero line (the one hand to meet the power and single-phase electricity, on the other hand, the user is not easy to do three single-phase distribution balance, so the zero line voltage), the other is basically balanced, does not need the zero line.

Q:How much money for rammer one meter three-phase cable?: According to the brand, the quality is different, there is a big difference in price! Had better go to local market to turn, 3*6+1 cable price from non-standard to national standard 10 yuan, -18 yuan one meter range, this kind of cable market is not pure national standard, can buy 3 main line, can achieve 5 square of good.

Q:Ramming machine operator must wear what labor protection supplies: 3. tamping machine not in frozen soil, stone, broken bricks and stone miscellaneous soil tamping, tamping machine turn, turn and not fiercely spreading does not help their free walk. 4. tamping machine operation, machine 2m no one. Taiwan compactor is hit, the left and right distance not less than 5m, and the distance of not less than 10m. The operating personnel must wear insulated shoes, wear insulated gloves.

Q:Carburetor gasoline leak automatic ramming machine: The oil needle on the carburetor float doesn't seal properly. Just open it and clean it

Q:Do not pull a gasoline rammer: If you do not describe your problem clearly, there is no way to help you.
