Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-slide piles, in particular to a new structure of a T-shaped self-balancing anti-slide pile in a filling area. Background Art
[0002] Anti-slide piles are piles that penetrate the landslide body and extend deep into the slide bed. They are used to support the sliding force of the slide body and stabilize the slope. They are suitable for shallow and medium-thick landslides and are a major anti-slide treatment measure. Wood piles, steel piles, concrete piles or reinforced (rail) concrete piles are selected according to the thickness of the landslide body, thrust size, waterproofing requirements and construction conditions.
[0003] When setting up anti-slide piles in high fill areas, the horizontal displacement of the pile top often exceeds the specification. The usual solution is to increase the cross-sectional size of the anti-slide piles or shorten the pile spacing, which leads to a significant increase in engineering costs. This problem is particularly prominent in soft foundations. In order to solve the above problems, a new anti-slide pile structure was developed. Utility Model Content
[0004] In view of this, the purpose of the utility model is to provide a new type of T-shaped self-balancing anti-sliding pile structure in the fill area which adopts the self-balancing structural principle and can significantly reduce the internal force of the anti-sliding pile structure and the horizontal displacement of the pile top, so as to overcome the shortcomings of the prior art.
[0005] The purpose of this utility model is achieved through the following technical solutions:
[0006] A new type of T-shaped self-balancing anti-sliding pile structure in the fill area includes an anti-sliding pile, the top ends of two or more anti-sliding piles are connected by a crown beam, a cantilever beam is provided in the middle section of the anti-sliding pile, wherein the lower section of the anti-sliding pile is arranged in a pile hole on the ground of the hole mouth, and the upper end surface of the cantilever beam is flush with the ground of the hole mouth and is arranged horizontally in the direction of the fill area.
[0007] The aforementioned new type of T-shaped self-balancing anti-sliding pile structure in the filling area is that a horizontal plate is laid above the two cantilever beams.
[0008] The aforementioned new type of T-shaped self-balancing anti-sliding pile structure in the filling area is that a pile inter-plate is arranged between two anti-sliding piles, the upper part of the pile inter-plate is connected to the crown beam, and the lower part is lower than the ground surface of the hole.
[0009] The aforementioned novel structure of T-shaped self-balancing anti-sliding piles in the filling area is that the cross section of the anti-sliding piles is circular or rectangular.
[0010] The aforementioned novel structure of the T-shaped self-balancing anti-sliding pile in the filling area is that the cross section of the cantilever beam is circular or rectangular.
[0011] The aforementioned novel structure of T-shaped self-balancing anti-sliding piles in the filling area is that the cross-sectional area of the cantilever beam is equal to or smaller than the cross-sectional area of the anti-sliding piles.
[0012] The beneficial effects of the utility model are as follows: by designing the anti-sliding pile as a new T-shaped anti-sliding pile structure, the cantilever beam located in the backfill area will generate a force in the opposite direction to the landslide body under the action of the backfill material, thereby effectively utilizing the self-balancing structural principle, greatly reducing the internal force of the anti-sliding pile structure, and greatly reducing the horizontal displacement of the pile top; and this structure is easy to construct and has a simple process, providing a new method for the design of anti-sliding piles in the backfill area of soft foundations, and has high practical value. A horizontal plate is laid above the two cantilever beams, which can ensure that the backfill self-weight is completely transferred to the anti-sliding piles to increase the balancing force.
