Anchor rod construction method for soil body and anchor rod assembly used thereof

Abstract

The anchor rod construction process includes the steps of: assembling the detachable anchor rod assembly with anchor ribs to the front end of drilling rod; rotating the drilling rod to set the said anchor rod assembly into soil and to required position while drilling hole; depositing solidifying liquid via the hollow passage in the drilling rod to the bottom of the hole to form large head for anchoring; and separating the anchor rod assembly from the front end of the drilling rod so as to withdrawing the drilling rod while retaining the anchor rod assembly inside the hole.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a construction technique for retaining soil, an underground continuous wall, and foundation pit support, and forming an anchor rod by resisting tension and pulling in the soil layer. Background technique [0002] In the past, the construction of traditional soil anchor rods included drilling holes, running anchor bars, and grouting multiple times, and the process was complicated. For the loose and weak soil with rich water content, the traditional anchor rod is like a nail inserted into a tofu block, which cannot form a hole, which may cause accidents such as thixotropic liquefaction and sand blasting. For this reason, people often choose to run a casing and then drill , run down the anchor bars, and perform multiple grouting, which makes the process more complicated and the cost further increases. In addition, the above process has the disadvantages of large pollution and small ...

[0002] In the past, the construction of the traditional soil anchor rod included drilling, lowering the anchor bar, and performing multiple grouting, which was a complicated process.

For the loose and weak soil rich in water, the traditional anchor rod is like inserting nails into a tofu block, which cannot form a hole, including accidents such as thixotropic liquefaction, sandblasting pipes, etc. For this reason, people often choose to lower the casing and then drill the hole , down into the anchor bar, and perform multiple grouting, which makes the process itself more complicated and further increases the cost. In addition, the above-mentioned process has the disadvantages of large pollution and small anchor diameter
