Abstract

The invention relates to a soil foundation multiple-cable antifloating foundation. The soil foundation multiple-cable antifloating foundation comprises an upper plate, a plurality of pulling-resistant filament anchor rods, cushion plates matched with the pulling-resistant filament anchor rods, and anchor plates matched with the pulling-resistant filament anchor rods, wherein the upper plate is embedded into a soil foundation, and the upper surface of the upper plate is higher than the ground surface; the upper plate is in a polygon shape; each corner of the upper plate is provided with an anchor rod hole I; the center of each cushion plate is provided with an anchor rod hole II; the bottom ends of the multiple pulling-resistant filament anchor rods are anchored, the top ends of the multiple pulling-resistant filament anchor rods penetrate through the anchor rod holes I in the upper plate and penetrate through the anchor rod holes II in the cushion plates correspondingly to be connected with the anchor plates; the pulling-resistant filament anchor rods are composed of pulling-resistant filaments; and waterproof explosives with detonators are bound to the lower portions of the corresponding pulling-resistant filaments, and the pulling-resistant filaments are evenly distributed on the periphery of the corresponding waterproof explosives with the detonators 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, the investment is remarkably reduced, and spoil is reduced.

Description

technical field

[0001] The invention relates to soil foundation reinforcement and foundation forms, in particular to a multi-cable uplift-resistant foundation of the soil foundation and a construction method thereof. Background technique

[0002] At present, 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 foundation mainly includes large excavation foundation, excavation and bottom expansion foundation, explosive expansion pile foundation, etc. difficulty, and there are problems such as large amount of engineering, long time-consuming, high cost, great damage to the environment, but limited resistance and unsatisfactory reinforcement effect. The large deformation and the stability of the foundation become the key issues that m...

Embodiment Construction

[0033] Such as Figure 1~3 As shown, the multi-cable uplift foundation of the soil foundation includes an upper plate 6 embedded in the soil foundation 1 and the upper surface is higher than the ground 17, a plurality of hair anchors 4 and backing plates 7 matched with the hair anchors 4 and Anchor plate8.

[0034] The upper plate 6 is polygonal, and each corner is provided with an anchor hole I; the center of the backing plate 7 is provided with an anchor hole II; the bottom ends of several hair anchors 4 are anchored, and their top ends pass through the upper plate 6 respectively. The anchor hole Ⅰ of the backing plate 7 is connected to the anchor plate 8 through the anchor hole Ⅱ of the backing plate 7; Or (and) constituted by other silk threads. The lower part of the tensile filament 11 is bundled with the water-resistant explosive 12 equipped with the detonator 10 , and the tensile filament 11 is evenly distributed around the water-resistant explosive 12 equipped with t...
