Construction method of grouting flower tube anchor rods in support process of soft soil slope

Abstract

The invention discloses a construction method of grouting flower tube anchor rods in the support process of a soft soil slope. Through a structure that flower tube anchor rods of the grouting flower tube anchor rods are combined with an anchor reinforcement, the anchor reinforcement is fixed in the flower tube anchor rods by adopting an anchor rod fixing bracket and a flower tube fixing bracket; secondary grouting is performed through double grouting holes to ensure the grip of a cement column after mud is solidified; and the strength of slope soil is strengthened, through secondary anchor spraying, a common system is formed by the anchor reinforcement, a concrete spraying layer and the slope, slope loosening and separation are prevented and controlled, the slope is stabilized, expandablesteel sheets at the tail ends of the flower tube anchor rods ensure large area contact with reinforcement meshes and the concrete spraying layer, a structural surface and a level are reinforced, the integrity and the self-supporting capacity of the slope are more effectively improved, and the development of deformation is inhibited. The method is strong in feasibility, low in cost, and high in safety and stability, the effect of uplift in soft soil area is significant, a great influence of soil properties is effectively solved, effective uplift resistance is provided for soft soil slopes, andthe construction method is suitable for promotion and application.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a construction method of grouting flower tube anchor rods in soft soil slope support. Background technique [0002] As an important form of geotechnical reinforcement, bolt support is more and more recognized due to its advantages of safety, high efficiency, and low cost, and has been increasingly recognized in the field of international geotechnical engineering. Many applications. However, bolt support also has its limitations, mainly due to the fact that it is greatly affected by the properties of the soil. When the soil layer is weak, it cannot provide effective pull-out resistance. Therefore, the application of this technology is largely limited in poor soil quality such as high groundwater level and silty soil. [0003] The grouting flower tube bolt support is produced under this background, and it belongs to a kind of foundation pit support system. The cement slurry i...
