Problems solved by technology

However, the production volume of piles of each specification is different, and the forecast needs fluctuate, and when multiple production lines are operated, the manufacturing efficiency is reduced.
In addition, inventory occurs when supply and demand are unbalanced, and PHC pipe piles must be managed on site according to various specifications, so on-site management is cumbersome

Embodiment Construction

[0096] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

[0097] figure 2 It is a drawing showing the process of each step of the non-discharge pile foundation construction method through the sediment gelation of the present invention.

[0098] Such as figure 2 As shown, according to the non-discharge pile foundation construction method of sediment gelation of the present invention, in order to penetrate the pile body 3 at the foundation 1, it includes: (a) the step of measuring the position of the pile body 3 to be constructed; (b) Rotate and penetrate the stirring device 6 at the construction site of the pile body 3 until the foundation is supported, so that the silt in the foundation 1 is softened, and the gelling agent is sprayed to the stirring device 6, and the softened silt is mixed with the gelling agent. stirring to make the sediment gel (gel); (c) remove the stirring device 6, ma...

Abstract

The invention relates to a non-displacement pile foundation construction method adopting sediment gelation. According to the non-displacement pile foundation construction method adopting sediment gelation, a pile body is penetrated into gelled sediment formed in the manner that sediment softened by means of rotary penetration of a stirring device and a gelling agent are mixed, and the pile body isinstalled on a support foundation; in this way, during pile body embedding construction, soil digging is avoided, the influence on the surrounding ground can be minimized, and the construction periodof a pile foundation is greatly shortened. The non-displacement pile foundation construction method adopting sediment gelation comprises the steps that (a) the position of a to-be-constructed pile body is measured; (b) the stirring device is rotationally penetrated into the pile body construction site until reaching the supporting foundation, so that the sediment in the foundation is softened, the gelling agent is sprayed to the stirring device, the softened sediment and the gelling agent are stirred, and then sediment is gelled; (c) the stirring device is removed, the pile body is penetratedinto the gelled sediment by means of the dead load, and the pile body is installed on the support foundation; and (d) the gelled sediment is maintained, and the pile body is fixed.

Description

technical field [0001] The invention relates to a kind of gelled sand formed by penetrating the pile body into the sand softened by the rotation of the stirring device and stirring the gelling agent, so that it is placed on the supporting foundation. When the body is buried in the construction, there is no excavation of soil, but the impact on the surrounding ground can be minimized, and the construction period of the pile foundation can be greatly shortened. It is a non-discharge pile foundation construction method that applies sediment gelation. Background technique [0002] Pile foundation construction methods are roughly divided into pile foundation construction methods in which piles are hammered on the soil layer, and embedded pile methods in which holes are drilled in the soil layer and then penetrated into the pile body. [0003] Although the pile foundation construction by the above-mentioned piling method is fast and simple, it generates a lot of noise and vibratio...
