Embodiment Construction

[0030] The utility model relates to an anchoring structure of an underwater magnetic branch steel bar anchor rod, which comprises a bolt rod, a casing is sheathed at one end of the bolt rod, an electromagnetic coil is wound outside the casing pipe, and the electromagnetic coil is sealed by a sealing box. The waterproof layer is heat-conducting silica gel coated outside the electromagnetic coil, and ring plates are arranged at both ends of the electromagnetic coil. The electromagnetic coil is connected with the controller through wires. One end of the anchor rod is obliquely fixedly connected with a tapered steel bar.

[0031] Such as Figures 1 to 5 As shown, the underwater grouting process is:

[0032] Step1: Select the diameter of the appropriate steel anchor rod 7 according to the drilled hole, and then weld the position of the steel anchor rod 7 solid section by electric welding, and weld several conical steel bars 1 to make the top tip-like.

[0033] Step2: Use the PVC...

Abstract

The invention discloses an anchoring structure and method for an underwater magnetic branch steel bar anchor rod. The structure comprises the anchor rod, a sleeve sleeves one end of the anchor rod, and an electromagnetic coil is wound around the sleeve and is sealed by a sealing box. According to the structure and method, the defects that a traditional underwater grouting operation technology is very difficult and mistakes are made frequently are effectively overcome, and the construction cost and the construction difficulty are greatly reduced.

Description

technical field [0001] The invention relates to an anchoring structure and method of an underwater magnetic branch steel bar anchor. Background technique [0002] With the continuous development and expansion of contemporary transportation lines, steel anchor technology is becoming more and more important in engineering construction, especially underwater steel anchor technology. Although my country's underwater steel anchor technology is constantly improving, but in this Among them, there are some problems, and we propose the following solutions to these problems. [0003] One is that most of the steel anchors still use underwater layering and segmented grouting, so they will be affected by the bottom pressure when entering the underwater grouting, which increases the difficulty of underwater operations for steel anchors. Due to the different quality of the steel anchor itself, it is more likely to cause accidents when the steel anchor is embedded underwater, such as damage...
