Non-symmetric composite reinforced concrete pouring supporting pile

Abstract

The invention relates to a non-symmetric composite reinforced concrete pouring supporting pile. The non-symmetric composite reinforced concrete pouring supporting pile comprises a tensile region and a compression zone, wherein the side surface of the tensile region is close to a soil layer; the side surface of the compression zone is away from the soil layer; reinforcement in the tensile region is formed by glass fiber-reinforced polymers arranged along a supporting pile in a circumferential direction at intervals or the glass fiber-reinforced polymers and steel bars alternately arranged along the supporting pile in a circumferential direction at intervals; the reinforcement in the compression zone is formed by steel bars arranged along the supporting pile in a circumferential direction at intervals; and the axial directions of the glass fiber-reinforced polymers and the steel bars are parallel to that of the supporting pile. According to the non-symmetric composite reinforced concrete pouring supporting pile disclosed by the invention, the usage quantity of the steel bars is greatly reduced through the reinforcement manner, so that steel materials are saved, and the non-symmetric composite reinforced concrete pouring supporting pile is energy-saving and environmentally-friendly; and besides, the corrosion resistance of the supporting pile is strengthened by the glass fiber-reinforced polymers, and the supporting pile is especially suitable for a seaside ground environment with a high content of chloride ions. According to the non-symmetric composite reinforced concrete pouring supporting pile disclosed by the invention, the utilization ratio of reinforcement materials is maximized, and particularly the adopted glass fiber-reinforced polymers are low in cost, so that the construction cost of the supporting pile is effectively reduced; and in addition, compared with the steel bars, the glass fiber-reinforced polymers are lighter, easier to transport, easier to hoist during production and manufacturing, and more convenient and quicker.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to an asymmetric composite reinforced concrete grouting support pile. Background technique [0002] Support piles are piles mainly used to bear lateral thrust, generally used for foundation pit support, slope support and landslide control, to bear horizontal soil pressure or landslide thrust, and usually require higher The reinforcement is also often used together with the anchor rod (cable) (pile-anchor structure). The reinforcement of the existing support piles is basically all made of steel bars. This type of support piles has the following disadvantages: 1. A large number of steel bars are required for reinforcement, resulting in high cost, and the heavy weight is not easy to hoist and construct; 2. For chloride ions The seaside environment with high content is easy to be corroded, which seriously affects the performance of the support piles. Contents of the invention ...
