Abstract

The invention provides a PSB finish-rolled deformed steel bar anti-floating anchor rod structure and a construction method thereof. The PSB finish-rolled deformed steel bar anti-floating anchor rod structure comprises a PSB finish-rolled deformed steel bar anchor rod body, a first anchor plate, a first anchor head, a second anchor plate and a second anchor head. After an anchoring body reaches thestrength required by tensioning, the PSB finish-rolled deformed steel bar anchor rod body can be tensioned and fixed through the first anchor plate and the first anchor head, the generated prestresscan enable the anchoring body to be in a pressed state, so that the anchoring body of the anchor rod is effectively controlled from generating cracks, the durability of the anti-floating anchor rod isimproved, and the anti-floating effect is consolidated. According to the construction method of the PSB finish-rolled deformed steel bar anti-floating anchor rod structure, prestress can be generatedonly by tensioning the anchor rod and additionally arranging the first anchor plate and the first anchor head to achieve the anti-cracking effect, and the construction method is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of foundation engineering, in particular to a PSB finish-rolled threaded steel anti-floating anchor structure and a construction method thereof. Background technique [0002] With the utilization of underground space and the increasing depth of building foundations, the problem of anti-floating also arises. It is very important to choose appropriate anti-floating measures. Compared with the anti-floating measures such as the dewatering and drainage method and the pressure-gravity method, the anti-floating anchor has the advantages of strong stratum adaptability, dispersing stress, easy construction, and cost saving, and has been widely used in the field of civil engineering. [0003] The fully bonded equal-section anti-floating anchor is a tension member. Under the action of water buoyancy, the anti-floating anchor will have cracks. Due to the existence of cracks, the anti-floating anchor steel will be corro...
