The difference between double pipe high pressure jet grouting pile and triple pipe high pressure jet grouting pile technology

The double-pipe high-pressure jet grouting pile uses high-pressure grouting pump and air compressor to work at the same time to generate high pressure, forming high-pressure cement slurry flow and cutting the soil into piles.
The triple-pipe high-pressure jet grouting pile uses special equipment to make holes first, and then inserts the grouting pipe. Cut the soil with high pressure water flow. At the same time, the air compressor is used to discharge the mud generated by the cutting body, and the grouting is synchronized.
Triple pipe and double pipe are different in construction technology. Triple pipe is made of water, gas and slurry to triple cut soil into piles, while double pipe is made of less water cutting, which has nothing to do with cement consumption.
The effect of different piles: high-pressure jet grouting pile double pipe pile diameter is about 800mm. The effective diameter of the triple tube can reach about 1200mm.
The cost is different: the time for double pipe material of high-pressure jet grouting pile is about 400kg, and that for triple pipe material is about 800kg.
The advantage of the triple tube method is that the high-pressure water pump directly presses the water, the machine is not easy to wear, and the higher pressure can be used to form a larger size of the consolidation body. Single pipe method, double pipe method, triple pipe method, multiple pipe method, etc., all have their own applicable conditions, can not say which is good which is not good, should be selected according to the engineering requirements and soil conditions. The above is about the double pipe and triple pipe high pressure jet grouting pile process difference is introduced.
