Drilling Rig for Construction of SMWBored Pile Drilling Rig

Drilling Rig for Construction of SMWBored Pile Drilling Rig

Product Features:

 

SMW, which is short of Soil Mixing Wall, is a construction method developed in Japan in 1976. Now it consists 50% of underground continuous wall constructions in Japan, and widely adopted in countries in southeast Asia, the United States, France etc. In Shanghai, Hangzhou, Nanjing and other cities of China, SMW becomes quite popular after its introduction years ago.
SMW uses multi-shaft auger to drill soil in situ, meanwhile pumps cement grout from the tips of the augers into the drilled holes. After sufficient mixing of the grout, H-shaped steel or other types of steel are embedded into the columns before the soil-cement mixture hardened, forming a underground continuous wall with rigidity and intensity. The wall could be used as retaining support or water seal. Three-shaft auger machine is commonly used.
 SMW method has the following advantages:
1.Low cost. Foundation retaining using SMW method with three-shaft auger machine is much more competitive in price than traditional method when constructing underground continuous wall.
2.Shorter construction period. SMW method consumes much less time than other methods. Under normal geographical conditions, it could build 70-80m² walls per shift.
3.Good seal quality. The wall is continuous without any cracks. Hydraulic conductivity can reach as much as 10-7cm/s.
4.No disturbance in nearby soils. SMW method would not cause hazards like ground subsidence, building inclining, road cracks or shift of underground facilities.
5.Wide range in use. It can be applied on cohesive soil, silt , sandy soil, gravel soil.
6.the waste soil is far less than other construction methods.

Q:What does a driver of a pile driver do? Playing in the sky?
The driver of a pile driver is a type of job that operates a pile driverWhen building a houseUse a pile driver to drive more than 20 meters of cement into the ground
Q:How to operate the excavator pile driver?
1, full hydraulic drive, you can rotate 180 degrees, easy operation;2, transportation is convenient, and can be connected with the excavator as a whole;3, can be applied to a variety of work sites, rainy days, but also in the river, surface, underwater operations;4, can hit, dial steel pile, cement pile, rail column, iron plate, H plate, drainage belt;5 、 the use of German hydraulic motor driven (rotating motor and vibration motor), small size, light weight, but can output high power and high speed, high reliability, strong and durable;
Q:What are the preparations for the piling site?
1, the pile position determination: according to the project provided by the construction unit and the pile axis location map of pile location, pile location must be accurate, and in the pile position by a soldering iron drilling, hole depth is 15~20cm, filled with lime, prevent in the process of driving the wrong pile.2. Pile up(1) pile stacking shall be determined by pile driving route and pile driving sequence(2) the site shall be level and level with three passes and one leveling. Remove obstacles in the ground, underground and air in the range of the moving of the pile driver. The wooden posts and the pile rings shall be of the same position, except for the contact between the pile and the pile, and nothing else shall be in contact with the pile so as to prevent cracks in the pile.(3) the strength of reinforced concrete precast piles must be up to 100% before they can be transported and piled3, the selection of pile machineAccording to the design of single pile bearing capacity and pile length, this project intends to use hammer weight 2.5t track type diesel pile driver.
Q:Do you make money on building pile drivers? How long will it take to recover the cost?
To be honest, no money, no problem, it's hard to have a client.My father worked as an electrician at the construction site for three years. I just asked him.Of course, you have connections, and you won't do it.The most crucial thing is the network, there is a market, that thing good, tens of millions, smashing hands, crying dead.Sure, you have connections, when I don't say..
Q:Which is better, a hydrostatic pile driver or a diesel pile driver?
Depends on what project you do, if there is no noise requirements, diesel hammer piling machine is better, a price at about 500000, back to Ben faster. The hydrostatic press is a bit heavy.
Q:What type of pile driver is this?
Hammer sinking pipe pile driver is a kind of large-scale machinery used in the construction of cast-in-place pile foundation. The general is a hammer a hammer down to the design depth, pipe are arranged at the front end of the pile head, to prevent dirt from entering the immersed tube. Then, the concrete is poured into the immersed pipe sleeve, and the concrete side lifting pipe is poured in the side, and the vibration is generated in the process of lifting the pipe, so as to achieve the compactness of the concrete.
Q:What is the working principle of a vibratory pile driver?
Vibratory pile driver is to use high frequency vibration to vibrate the pile body with high acceleration to transfer the vertical vibration of the pile to the pile body, so that the soil structure around the pile changes because of the vibration and the strength decreases.
Q:What are the prospects for a small pile driver and a foundation pile driver? Will it make money?
like Hunan Huilong piling machine is generally divided into: Machine lock rod rotary drilling rig, caterpillar rotary drilling rig, crawler wheel screw drilling machine, rotary drilling rig.
Q:How about the hammer head of hydraulic pile driver is too big?
You can only use the nitrogen charging device to release the nitrogen from the hydraulic hammer, and remember that the value is better than the 1-1.2
Q:What kind of excavator like excavator is easy to learn?
Is a rotary drilling rig, difficulty varies, excavators than boring work.AskI'm not talking about steel plate piles!Chasing the answerYes, it's broad. There is steel wire hanging. It's boring, too
