Embodiment 1

[0034] This embodiment provides a new type of anti-floating anchor rod, including bottom rods, middle rods and end rods spliced ​​in sequence, as attached figure 1 As shown, the bottom rod includes a shaft, one end of the shaft is connected with the threaded drill bit 1, the other end is provided with a connection port 3, and the shaft body is provided with a grouting port 2; as attached figure 2 As shown, the middle rod includes a shaft, the shaft is provided with a grouting port 2, and the two ends of the shaft are respectively provided with connection ports 3; image 3 As shown, the top bar includes a shaft, the shaft is provided with a grouting port 2, one end of the shaft is provided with a connecting port 3, the other end of the shaft is connected with an anchoring steel bar 4 and a grouting port is provided at the end of the shaft. Entrance 5. The bottom rod, the middle rod and the end rods are all hollow rod bodies. According to actual needs, the number of intermedi...

Embodiment 2

[0039] This embodiment provides a new type of construction method for assembling anti-floating anchor rods. Powered by a drilling rig, the threaded drill bit of the bottom rod is used to excavate underground. Every time a certain depth is excavated, the middle rod body is connected and installed above the bottom rod through the connection port. When the rod body is excavated After reaching the design depth, install the top bar, connect the grouting equipment to the slurry input port of the top bar, grout the anchor hole, and complete the anti-floating anchor construction after filling.

Abstract

The novel anti-floating anchor rod comprises a bottom rod, a middle rod and an end rod which are sequentially spliced, the bottom rod comprises a rod body, one end of the rod body is connected with a threaded drill bit, the other end of the rod body is provided with a connecting opening, and a grouting opening is formed in the rod body; the middle rod comprises a rod body, a grouting opening is formed in the rod body, and connecting openings are formed in the two ends of the rod body respectively. The top rod comprises a rod body, a grouting opening is formed in the rod body, a connecting opening is formed in one end of the rod body, the other end of the rod body is connected with an anchoring steel bar, and a slurry injection opening is formed in the end of the rod body. The invention further discloses a construction method of the novel anti-floating anchor rod. According to the method, the material utilization rate of the anti-floating anchor rod body can be increased, the field processing workload is reduced, material waste is reduced, the quality stability of the rod body can be effectively improved, the quality management difficulty is reduced, and the grouting quality is improved.

Description

technical field [0001] The invention relates to an anchor rod and a construction method thereof, in particular to a novel anti-floating anchor rod and a construction method thereof, and belongs to the technical field of anchor rods. Background technique [0002] The anti-floating anchor rod is one of the main technical means for the basement structure to resist the buoyancy of groundwater in construction engineering, and it is of great significance to ensure the safety, applicability and durability of the basement structure. The traditional anti-floating anchor construction technology is: hole forming-hole cleaning-placing anchor and grouting pipe-grouting. Traditional crafts need to face a series of technical problems during the construction process, which restricts the construction speed, quality and economy. [0003] Common problems in current prior art include: [0004] 1. The grouting pipe needs to be bundled with the anchor bar and placed in the anchor hole synchrono...
