Cloth bag pile structure equipped with unfoldable steel bar framework and construction process thereof

Abstract

The invention discloses a geotextile bag pile structure equipped with an unfoldable steel bar framework and a construction process thereof. A folded steel bar framework structure is adopted; the structure is shrinkable; a group of telescopic frames are arranged between two vertical bars at intervals; the telescopic frames are in articulated connection with the vertical bars through rotating headsto form a structure similar to a telescopic door; when the spacing between the vertical bars is reduced, the telescopic frames can rotate along the rotating heads and own rotating shafts; the diameterof the structure is reduced; when the cloth bag is pulled, the spacing between the vertical bars is increased, the telescopic frames are stretched until the steel bar framework is unfolded, and the diameter of the structure is increased. According to the geotextile bag pile structure equipped with the unfoldable steel bar framework and the construction process thereof, the geotextile bag is connected with the folded steel bar frame structure through composite fiber bars; when the pile structure is constructed, the pile body is firstly placed down, then the concrete is poured, the cloth bag isexpanded to generate pressure; the composite fiber bars are used for pulling the steel bar frame structure to be unfolded, and a high-strength reinforced concrete cloth bag pile structure is automatically formed.

Description

technical field [0001] The invention belongs to the field of pile foundation construction, and in particular relates to a bagged pile structure and construction technology equipped with an expandable steel bar skeleton. Background technique [0002] With the development of traffic construction projects, road and bridge pile foundation construction techniques are diversified. Among them, the bag pile not only has the functions of isolation, drainage and reinforcement, but also can accelerate soil consolidation, improve the bearing capacity and composite modulus of the soil, reduce the compression deformation of the soil and the settlement of the foundation, and effectively control the post-construction settlement of the weak foundation. , and has a good effect in preventing saline soil from corroding structures. At present, the construction technology of bag pile technology is reasonable, the operability is strong, and the quality is relatively reliable. However, the bearin...

Problems solved by technology

However, the bearing capacity of bag piles is not only derived from the friction between the pile body and the soil around the pile, but also related to the strength of the pile body. The existing bag piles are only poured with concrete and cannot be reinforced. Bending and Shearing Capacity Requirements

Moreover, for common bag piles of the same pile type, due to differences in construction technology, local differences in geological conditions, and differences in the amount of concrete, it is easy to cause uneven settlement of the concrete in the bag when it solidifies, resulting in the discreteness of the bearing capacity.
