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: Pile up can not go down, how to deal with?
- 3, if the formation is hard, the pile length is not enough, can not meet the design requirements, to design out a modification or replacement of pile type; the guiding hole and then continue to play, it is in a pile by auger drilled Kong Lai, then pile down.
- Q: The difference between diesel pile driver and impact drilling machine
- A diesel pile driver: like a hammer hitting a nail, it is hit by a hammer.Percussive drill: like percussive drilling, it is drilled out during impact.
- Q: What is an impact pile driver?
- You mean the kind of pile driver that used to use high explosive diesel engines to produce impact?The principle is like using the percussion hammer nails, using a hammer impact in the nail head will generate the nail.It's very seldom used now.
- Q: Why levy piling
- Like a chopstick, inserted into the soil is not directly on the ground than in a more stable, the pile is equivalent to the chopsticks into the earth part.
- Q: Is the architecture of the pile driver strong in single core performance or multi - core capability? Or?
- What do you mean? Multi thread advantage with core?Multi thread tasks must be the core, the more advantages.
- Q: The piling machine and the appearance are not considered as large machinery import and export fields
- See what kind of bar! If it is a small blue ocean highway, the pile driver is not large, even if the loading type.
- Q: How many kinds of pile driver are there?
- The cylinder type diesel hammer takes the cylinder as the hammer seat and directly uses the lengthened cylinder to guide the inner wall. The two guiding rods are omitted, and the plunger is a hammer head, which can move up and down in the cylinder. When piling, the pile cap at the bottom of the hammer block is pressed on the top of the pile, lifting the plunger with a hook, and then decoupling and downward impacting to compress the air enclosed in the cylinder. And fuel injection, explosion, shock, ventilation and other work processes. Diesel hammer work is on compression ignition diesel to start, it is necessary to ensure the closed gas cylinder reaches a certain compression ratio, sometimes piling in soft soil layer is often because the reaction is too small, the amount of compression is not sufficient to ignite the ignition, it needs to use the hook to lift a hammer from multiple impact, to start. The hammer seat of the diesel hammer is provided with a fuel injection pump, an oil tank, a cooling water tank and a pile cap. The movable gap between the plunger and the cylinder is sealed with an elastic plunger ring. Four, hydraulic hammer piling machine is a diesel belt start, to the oil pressure as the driving force, can be adjusted according to the formation of different soil pressure, in order to achieve the appropriate impact force for piling, is a new type of pile driver. Small and medium-sized hydraulic pile driver, commonly used in highway guardrail piling, highway guardrail construction. Similar pile driving equipment are: hydraulic pile driver, road pile driver, guardrail, pile driver, road drilling machine.
- Q: PV pile driver
- Shandong Tengzhou production of this idiot manufacturers have a few, can come to Shandong to look strong, has many years of construction experience in complex terrain. Can prevent landslides and broken stones.
- Q: How do I maintain the hydraulic pile driver I bought?
- Pay attention to the following: the type of project to be used;
- Q: How can I find a pile driver?
- Now a lot of special construction pile foundation construction company, contact them to see
