Embodiment Construction

[0040] The following is attached Figure 1-3 The application is described in further detail.

[0041] The embodiment of the application discloses a reinforcement structure of a stirring pile in a muddy soil layer.

[0042] refer to figure 1 and figure 2 A reinforcement structure for mixing piles in silty soil layers includes a mixing pile body 1 and reinforcing ribs 2, the mixing pile body 1 is a cylindrical pile body, and the reinforcing ribs 2 are provided for improving the distance between the mixing pile body 1 and the silty soil layer. Reinforcement mechanism 3 with high connection strength, reinforcement mechanism 3 is made up of connection core 31 and several outer ribs 32 uniformly hinged on the side of connection core 31, connection core 31 is coaxially sleeved on the bottom of reinforcement rib 2 and connected with reinforcement rib 2 Welding, the length of each externally expanded rib 32 is equal, and the length of the externally expanded rib 32 is greater than ...

Abstract

The invention relates to a mucky soil layer mixing pile reinforcing structure and a construction method, and is applied to the field of mixing pile technology, the mucky soil layer mixing pile reinforcing structure comprises a mixing pile body used for reinforcing a mucky soil layer, and reinforcing ribs are arranged in the mixing pile body used for reinforcing the mucky soil layer in the depth direction; the reinforcing ribs are provided with reinforcing mechanisms used for improving the connecting strength between the mixing pile body and a muddy soil layer on the peripheral side of the mixing pile body. The reinforcing mechanism comprises a connecting core and a plurality of external expansion ribs, the connecting core is arranged on the reinforcing rib in a sleeving mode, the external expansion ribs are hinged to the peripheral side of the connecting core at intervals, and the reinforcing rib is provided with an external supporting mechanism used for abutting the external expansion ribs into a muddy soil layer on the peripheral side of the mixing pile body. The stirring pile has the advantages that the stirring pile and the surrounding muddy soil layer are connected more tightly, and then the connecting strength of the stirring pile and the surrounding muddy soil layer is improved.

Description

technical field [0001] The present application relates to the technical field of mixing piles, in particular to a reinforcement structure and construction method of mixing piles in silty soil layers. Background technique [0002] Stirring pile is a method used to reinforce saturated soft clay foundation. It uses cement as a curing agent, and through a special mixing machine, the soft soil and curing agent are forcibly stirred deep in the foundation, using the gap between the curing agent and soft soil to A series of physical and chemical reactions produced harden the soft soil into a high-quality foundation with integrity, water stability and certain strength. [0003] In the related technology, when constructing the muddy soil layer, the construction personnel firstly position, center and level the mixing pile machine; The drill rod drives the mixing head to sink; and during the drilling process, the cement slurry is sent to the outlet of the mixing head through the mortar...
