Jointed rock mass foundation pilling-pressure-shift-resistant foundation and construction method thereof

Abstract

The invention relates to a jointed rock mass foundation pilling-pressure-shift-resistant foundation. The foundation comprises a pulling-resistant filament anchor rod, an upper plate, a cushion plate and an anchor plate, wherein the pulling-resistant filament anchor rod is perpendicular to the ground; the upper plate and the cushion plate are each provided with an anchor rod hole; the upper end of a rod body of the pulling-resistant filament anchor rod sequentially penetrates through the anchor rod hole of the upper plate and the anchor rod hole of the cushion plate to be connected with the anchor plate; the rod body of the pulling-resistant filament anchor rod is composed of pulling-resistant filaments; and a waterproof explosive with a detonator is bound to the lower portions of the pulling-resistant filaments, and the pulling-resistant filaments are evenly distributed on the periphery of the waterproof explosive with the detonator in the circumference direction. The invention further discloses a construction method of the foundation. The structure is simple, the construction mode and the foundation mode are changed radically, thus, the investment is reduced, spoil is reduced, and the environment is protected.

Description

technical field [0001] The invention relates to fissure rock mass reinforcement and foundation forms, in particular to a fissure rock mass foundation anti-pull and pressure displacement foundation and a construction method thereof. Background technique [0002] For fractured rock mass, structural plane is one of the main controlling factors of its physical and mechanical properties. The existence and characteristics of structural plane play a decisive role in controlling the deformation, destruction and scale of fractured rock mass. [0003] Most of the foundations are compression foundations, that is, the foundation mainly bears the vertical load imposed by the superstructure and meets the deformation and stability requirements, typically including independent foundations, strip foundations, raft foundations, etc. The uplift-resistant foundations mainly include large-scale excavation foundations, excavation-excavation foundations, and explosive-expanded pile foundations, et...

AI Technical Summary

Problems solved by technology

[0004] As far as the anti-compression foundation is concerned, the cracked rock mass is a good natural foundation, and its construction is very simple; and on the cracked rock mass foundation, whether it is a large-scale excavation foundation, excavation and bottom expansion foundation, or explosive expansion pile foundation The construction of these projects is relatively difficult, and there are problems such as large amount of engineering, long time consumption, high cost, and great damage to the environment, but the resistance that can be provided is limited, and the reinforcement effect is not ideal. For example: large-scale excavation of foundations The main dimensions of the basement are determined by the requirements of its uplift stability. In order to meet the requirements of uplift stability, the size of the foundation must be increased, the spoils must be increased, and the damage to the environment must be aggravated.
