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:How to hit a pile of photovoltaic power generation?
Do you have anything to live with? I have a photovoltaic machine. What ground is it, earth or stone?
Q:Piling of percussive drilling
7, the drilling process control should be rigorous, but also do not have to worry about failure, a reasonable choice of treatment methods, generally can be solved, the common, foot blade perforation, hole collapse, partial hole, cross hole, drilling, drilling, drilling buried crane, well preventive measures are generally not in advance, very important duty responsibility. 8, the remaining holes, steel cage decentralization, concrete pouring, sealing and other are more conventional, do not write more. But the bottom of the hole, sediment, sediment, etc. must be recycled clean, otherwise it will be buried in the later works of greater risk. When the concrete is poured, the bottom concrete under the impact of residue inclusion in steel or bond caused by defects in the pile in concrete, on the upper structure of the load transfer to the bottom of the pile, the structure will definitely should produce uneven settlement for residue.
Q:Buying a pile driver doesn't know how to make a profit Has anyone done that yet?
Because, after all, the pile driver is not only a few years, the choice of good quality in the early may not be cost-effective, but after taking into account, or suggest that you buy a little bit of the machine. After all, if the driver problem that you every two or three days, the work is not good for.
Q:What are the prospects for a small pile driver and a foundation pile driver? Will it make money?
Small rotary drilling rig prospect is very good, is generally 40 meters below the depth of drilling rig is defined as a small rotary, 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:Precast pile, artificial dig hole pile, sinking pipe filling pile, spiral drilling pouring pile and powder spraying pile.
You need to use the term piling machine and every possible operation and maintenance costs have a general understanding, if each year period divided by total amount plus maintenance costs less than the lease, you can consider buying, similar or greater, or lease more appropriate.
Q:What's the difference between a walking tube type diesel pile driver and a track type diesel pile driver?
The piling machine works on the top and bottom of the pile hammer. The pile hammer moves up and down on the 2 rail. It is called a track type diesel pile driver, and the pile hammer operates in the pipe way up and down. It is called a tube type diesel pile driver
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:Grounding of pile driver for help
Five core power cable, PE core wire may reach 16 square, in pile machine within 30 meters hit a 3 meter long galvanized angle (angle 50X5X3000), the head of a hole on the M10 (or M12) galvanized bolts, connecting 16 square BVR yellow green color line to the pile machine (repeat grounding), angle head (to prevent the hammer head welding deformation angle) a piece of iron, if you want to reuse (pull out in place again), can be connected with the hanging wire rope or a hook hole in angle steel.
Q:How much is the hydraulic pile driver?
Between 16-40, 000. Different manufacturers. Different tonnage difference big ah, soft land dozen20 tons will be enoughI hope my answer is useful to you, if satisfied, please take ~!
Q:What's the special use of a pile driver?
Moreover, the torque of the hydraulic power head is 2-3 times as much as that of the ordinary three ring power head. It is more suitable for complex formation than the traditional long spiral, and the construction efficiency is more efficient. Long spiral drill in the type piling machine is the use of a more extensive, and for starting current understanding, we can get better in the construction layout, so as to avoid the occurrence of the voltage is not enough at the time of construction.
