File foundation construction method and its device {FILE FOUNDATION WORK AND EQUIPMENT}

The present invention relates to a pile foundation construction method and a device for solidifying the ground by constructing piles in the ground to solidify the foundation of various buildings such as high-rise building, for consolidation excavation equipped with a troulsk in pile foundation construction After forming the excavation hole with auger, the cement paste is injected into the excavation hole, and the pile with the pile end member installed is piled with the rotary press function. Low vibration and low noise pile foundation construction method and device for firmly constructing the foundation ground of building by tip support

In general, in the construction of various buildings such as high-rise building, it is driving the pile on the soft ground to solidify the foundation of the building, and this construction is a very important construction for the foundation of the building.

For pile construction as above, the leader was installed in the crane, and the pile pile was piled by driving using drop hammer, diesel hammer, hydraulic hammer, etc., or the pile pile was piled by excavation method. In many cases, the site collapses, and the casing method was used to press the cement pipe and pile into the excavation pile.

However, in the conventional pile construction method as described above, the pile construction due to driving generates a lot of noise and dust due to vibration, and when the vibration is high, it causes damage to surrounding buildings and environmental pollution. There were many occurrences, and there was a problem in the production of piles that sufficiently sustained the driving, and there was a problem that the pile was frequently broken during the driving. In addition, even when the pile construction is carried out by the casing method, the installation cost of the casing tube and the consumable bit are installed so that the construction cost is high, the safety and energy generation is uncertain, and the scope of excavation is wide, and the cement paste is consumed more than necessary. As the working period is longer, there is a problem that the cost increases.

In addition, in order to supplement the problems of the rudder construction method and the excavation construction method in the pile construction as described above, a heavy excavation construction method is installed in which the pile is constructed by pressure input by a cylinder or the like while excavating the pile tip by installing an auger in the pile. However, this method is also expensive and there is a problem that cracks in the pile due to the pressure caused by gravel filled in the pile during construction,

In recent years, a trowel (a trowel) is used for an excavation screw used in the excavation method of a pile.
