[0011] To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] Example

[0013] like Figures 1-4 As shown, the end-bearing anti-buoyancy anchor rod of this embodiment is mainly composed of a bearing body 1, an end cap 2, a base 3, and a tension member 4.

[0014] The support body 1 can be made of corrugated steel pipe to improve pull-out resistance, and its front end is connected to the base 3. The base 3 has a stepped cylindrical structure, including a main body that can be fixed inside the support body 1 and a flange that abuts against the front end of the support body 1. A hole for connecting to the tension member 4 is provided at the center of the base 3, and the tension member 4 passes through the support body 1 and connects to the hole of the base 3. In this embodiment, a threaded hole is provided at the center of the base 3, and the tension member 4 is a screw, and the two are connected together by threads. The end cap 2 is fastened to the base 3 to cover the front end of the tension member 4. Specifically, the rear end of the end cap 2 is provided with a female thread, and the flange of the base 3 is provided with a male thread that mates with the female thread of the end cap 2, and the two are fastened together by threads.

[0015] The rear end of the main body of the pedestal 3 is chamfered to facilitate insertion into the carrier 1. The pedestal 3 and the carrier 1 are movably connected. During installation, the end cap 2 and the tension member 4 are screwed onto the pedestal 3 respectively, and the main body of the pedestal 3 is inserted into the carrier 1.

[0016] In use, first drill anchor holes in the ground, connect the sleeve to the bearing body 1 of the aforementioned end-bearing anti-buoyancy anchor rod, and insert it into the anchor holes. Next, inject mortar, cement emulsion, or other setting materials until the bearing body 1 is submerged. After the setting material hardens, tighten the threaded rod, which serves as the tension member 4 and is exposed outside the hole.

[0017] In this invention, the rear end face of the flange of the base 3 is provided with a groove. When the main body of the base 3 is inserted into the carrier 1, the front end of the carrier 1 can be inserted into the groove of the base 3, which can prevent the two from deflecting and can also facilitate welding and fixing of the two under certain circumstances.

[0018] In summary, existing anti-buoyancy anchors that use metal plates as load-bearing bodies have their tensile force mainly concentrated at the bottom metal plate, resulting in stress concentration and a relatively small maximum tensile force. Therefore, this invention, through the combined structure of end cap 2, base 3, and tubular load-bearing body 1, can withstand large tonnage pull-out forces with small displacement, effectively reducing the deformation of the foundation pit. At the same time, it is very convenient to install and construct, which greatly improves the efficiency of construction.

[0019] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the essence of the present application should be covered within the protection scope of the present application.
