Detailed Product Description

It is a small of rock drill and powered by air compression,can be used for drilling on the hard rock and rock with medium hardness.

It is a small type of rock drill and powered by air compression. It can be used for drilling on the hard rock and rock with medium hardness. It has smart structure, easy operation, and two working methods: dry drilling and wet drilling. The wet drilling can reduce dust effectively, which performs certain function of labor protection.

Features: The shell is made of the high performance ADI (Austenite and Bainite Ductile Iron) casting, which makes it not only having high strength as carbon steel forging, but also better abrasion resistance than that of the carbon steel forging. Therefore it extends the working life effectively.

Q: Should the foundation be compacted by tamping machine?: Should the foundation be compacted by tamping machine?The general case thinnish replacement can tamper compaction coefficient is not high 0.93The requirement of filling and filling of sandstone is very high. 0.97, the vibrating roller must be used

Q: What materials need to tamper: It refers to the use of tamping tamping compaction.For example, when you build a house, you have to dig the ground first.

Q: The advantages and disadvantages of gasoline and electric rammer breaststroke tamping rammer: Tamping large area sand and crushed stone should be done by flat rammer,A vertical impact ram shall be used for tamping the narrow groove foundation of clay

Q: Buy a second-hand caterpillar crane rammer, about how much money: Take a look at the used car market, a penny a cargo, must see the object and then bid, so as not to be deceived, used car remember not online shopping.A high quality steel wire rope should be used by a crane user. It should be a steel wire rope with long service life and high quality and stability.

Q: The slope, there is a tamper budget, is the ramming area is how calculated?Because is the rammer labor costs so much to calculate the consolidation area altogetherIn particular, the area needed to fill the slope (I would like to know what the area is) rather than the entire surface area: No matter how many layers, the floor area of the ground surface is constant, so the area required by the ground surface is calculated.

Q: Ramming machine excavator and compacted soil which good?: When the excavator can tamper with, because of a large amount of backfill construction, ramming machine is too slow, the excavator bucket inside will be filled with soil, and then down the row, when ramming machine, as for the effect, general.

Q: The story of a ramming machine on the trip what's wrong.: Hello, your rammer is not an inverted switch, if you check the reverse switch wiring is not wiring errors or contact adhesion,

Q: Gasoline is what reason no vibration rammer: If the gasoline engine is working properly, the tamper does not vibrate. First, check that the oil is still there. (there is an oil drain under the retractable spring rubber).

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: How to adjust the ignition timing of gasoline rammer: The movement of the piston four stroke engine when the valve action must be controlled. It said the valve action time and the state must be consistent with the movement of the piston and the state of the moment, and the crank shaft and the cam shaft is not in a line, they must be connected to the transmission system, (of course, there are one part is under the camshaft...
