Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] refer to figure 1 and figure 2 , a simple device for constructing tree branch piles in the present invention includes a guide tube 1 and a soft pile cover 3, the bottom of the guide tube 1 is provided with a closed head 2 that forms a temporary connection with it, and the soft pile cover 3 is placed in the inner cavity of the guide tube 1 middle. The soft pile sleeve 3 has a main pile sleeve 31 extending longitudinally and supporting pile sleeves 32 distributed thereon, and the cavity of the main pile sleeve 31 communicates with the cavity of each supporting pile sleeve 32 . After pouring the branch pile pouring material into the soft pile cover 3, the main pile cover 31 and each support pile cover 32 are expanded into a tree shape.

[0014] The guide pipe 1 guides the construction of the branch pile in soft soil, and provides a channel for t...

Abstract

The invention discloses a simple device for construction of a branch pile. The simple device is used for enabling the branch pile to be smoothly formed into a pile in soft soil and is simple and convenient in construction. The simple device comprises a guide pipe and a soft pile sleeve; a closing head which is temporarily connected with the bottom of the guide pipe is arranged at the bottom of the guide pipe; the soft pile sleeve is arranged in an inner chamber of the guide pipe and is provided with a main pile sleeve extending longitudinally and branch pile sleeves which are distributed on the main pile sleeve; a cavity of the main pile sleeve is communicated with the cavity of each branch pile sleeve.

Description

technical field [0001] The invention relates to geotechnical engineering, and is particularly suitable for a branch pile construction device for reinforcing flow-plastic soft ground. Background technique [0002] A large number of deep soft soil foundations are widely distributed in the coastal areas of our country. When building a filling project on them, the deep soft soil foundations must be reinforced. At present, the commonly used methods for deep soft soil foundation reinforcement include mixing piles, high-pressure rotary grouting piles, pipe piles, and bored piles. At present, there are certain problems in commonly used piles, such as the limited treatment depth of mixing piles and jet grouting piles, the reinforcement effect is limited when the bearing capacity and settlement requirements are strict, the suspension piles are not suitable for pipe piles and bored piles, and the investment is very huge. [0003] In order to solve the above problems, the applicant dis...
