Abstract

The invention relates to an anti-pulling and anti-skid foundation. The anti-pulling and anti-skid foundation comprises a square foundation plate, a set of beard and hair anchor rod bodies, a plurality of total-length bonding anchor rods, cushion blocks and anchor plates, wherein the square foundation plate is embedded in a base, the upper surface of the square foundation plate is higher than the ground, and the cushion blocks and the anchor plates are matched with the beard and hair anchor rod bodies and the total-length bonding anchor rods. First anchor rod holes are formed in the center of the foundation plate, and each of corners of the foundation plate is provided with a second anchor rod hole. The center of each cushion block is provided with a third anchor rod hole. The bottom ends of the beard and hair anchor rod bodies are anchored, and the top ends of the beard and hair anchor rod bodies penetrate the first anchor rod holes and penetrate the third anchor rod holes to be connected with the anchor plates together. The beard and hair anchor rod bodies are made of pulling resisting fine wires, waterproof explosive with a detonator is bundled to the lower portions of the pulling resisting fine wires, and the pulling resisting fine wires are evenly distributed around the waterproof explosive with the detonator in the perimeter direction. The top ends of the total-length bonding anchor rods penetrate the second anchor rod holes and penetrate the third anchor rod holes to be connected with the anchor plates together. The invention further discloses a construction method of the foundation. The anti-pulling and anti-skid foundation is simple in structure, and investment is saved.

Description

technical field [0001] The invention relates to a foundation and a foundation form, in particular to an anti-pull and anti-skid foundation and a construction method thereof. Background technique [0002] At present, most superstructures are heavy and occupy a large area. The foundation is a compressive foundation, that is, the foundation mainly bears the downward load imposed by the superstructure and must meet the deformation and stability requirements. When the foundation meets the above requirements, It can meet the anti-overturning requirements. Typical foundation types of this type include 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, etc.; The backfill soil constitutes the uplift-resistant soil to maintain the stability of the foundation; the excavated and enlarged bottom foundation categor...
