Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0024] see figure 1 , The uplift-resistant structure described in this embodiment is mainly used in stiffened piles with recyclable reinforced bodies. The stiffened pile includes a pile body 6 formed by jet-jet mixing or cement grouting. The pile head part contains a columnar uplift-resistant structure 3, and the reinforced body 5 is U-shaped and hangs around the column-shaped uplift The top of the structure 3 is folded back, and the reinforcing body is a whole unbonded steel strand, which is convenient for extraction.

[0025] see figure 2 , the pull-out structure 3 is a hollow cage-like structure, including three or more vertical braces 31, and a plurality of transverse braces 32 are arranged between the vertical braces 31. The pull-out st...

Abstract

The invention provides a stiffening pile used for recyclable reinforcement bodies in mealy sand layers. An anti-pulling reinforcement body wound and hung at the end portion of an anti-pulling structure body is arranged at the periphery of a center hole and not overlapped with the center hole, the stiffening pile for the recyclable reinforcement bodies forms a cemented soil mixing body and simultaneously brings the reinforcement bodies into a specified position. The stiffening pile used for recyclable reinforcement bodies in mealy sand layers effectively resolves the problem of constructing the stiffening piles of the recyclable reinforcement bodies in running water sand blast soil layers.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to stiffening piles used in deep foundation pit support engineering. Background technique [0002] Currently commonly used deep foundation pit support engineering, cement-soil stiffened piles have high pull-out resistance, and have been applied in some weak soil layers, but the steel strands used for the reinforcement body are completed in the foundation pit enclosure structure After functioning, it often remains underground to form obstacles, thus limiting the application of this type of support. For this reason, after the supporting structure is completed, the reinforced body can be recovered from the soil, which is an urgent problem to be solved in the engineering field. [0003] The patent applied by the applicant of this patent, the patent name is: a stiffening pile with recyclable reinforcement body, application number 201110209397.1, publication number CN102359107A...
