Problems solved by technology
[0003] Whether it is the foundation of large excavation, the foundation of digging and expanding the bottom, and the construction of explosive expansion pile foundation, it is difficult to construct, and there are large quantities of work, long time consumption, high cost, and great damage to the environment. However, the resistance that can be provided is limited, and the reinforcement effect is not ideal. For example, the main dimensions of large excavation foundations are determined by their pullout stability requirements. In order to meet the pullout stability requirements, the foundation size must be increased. It is bound to increase the spoil and aggravate the damage to the environment

Embodiment Construction
[0021] like figure 1 , figure 2 Shown, a kind of anti-uplift anchor foundation, it comprises the anchor bar body 4 that is obliquely inserted into the ground 11 and is hair-shape. The anchor rod body 4 is composed of tensile filaments 8, that is, steel wires or (and) other wires that can undergo large deformation under the action of an explosion. The lower part of the tensile filament 8 is bundled with the water-resistant explosive 9 with the detonator 7 , and the tensile filament 8 is evenly distributed around the water-resistant explosive 9 with the detonator 7 along the circumferential direction.
[0022] The construction method of the anti-lift anchor foundation comprises the following steps:
[0023] (1) According to the design requirements, drill holes 3 are set on the rock and soil mass 1;
[0024] (2) Place part of the water-resistant explosive 9 at the bottom of the borehole 3, and use its explosion to push away the weak mud in the cracks of the rock and soil body...

The invention relates to an anti-uplift anchor foundation. The anti-uplift anchor foundation comprises an anchor rod body which is obliquely inserted into the ground and is in a beard and hair shape. The anchor rod body is composed of tension thin wires. A water-resistant explosive filled with a detonator is bundled on the lower portions of the tension thin wires, and the tension thin wires are evenly distributed on the periphery of the water-resistant explosive with the detonator in the perimeter direction. The invention further discloses a construction method of the anti-uplift anchor foundation. According to the anti-uplift anchor foundation and the construction method thereof, the structure is simple, the construction mode and foundation mode are changed fundamentally, and therefore investment is reduced, waste soil is also reduced and the environment can be protected.
Description
technical field [0001] The invention relates to a structure form of a pull-resistant anchor foundation, in particular to a pull-resistant anchor foundation and a construction method thereof. Background technique [0002] 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 refers to the foundation that is filled with concrete and steel skeletons in the earth tire excavated by machinery or manually. Keep the uplift of the foundation stable; Explosive expansion pile foundation refers to the short pile foundation at the enlarged end that is poured with concrete and steel skeleton in the soil tire formed by explosion expansion. The uplift-resistant soil is basically close to the undisturbed natural soil. [0003] Whether it is ...
