Embodiment Construction

[0041] In order to make the technical means, innovative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0042] like Figure 1-Figure 13The shown anti-floating anchor 2 in soft soil includes a round pipe 3 , a driving device 4 , a rod 5 and a delivery chamber 6 . The lower part of the circular tube 3 is solid with an opening at the top, and has a hollow chamber communicating with the opening at the top. The conveying chamber 6 is arranged on the solid body at the bottom of the round pipe 3. The conveying chamber 6 is composed of a blind hole vertically opened on the solid body and a blind hole horizontally opened on the side wall of the round pipe 3. The two blind holes Connected to form an L-shaped delivery chamber 6; the delivery chamber 6 is a through hole, the opening of the delivery chamber 6 close to the outer wall of the round tube 3 is a...

Abstract

The invention discloses an anti-floating anchor rod in soft soil. The anti-floating anchor rod comprises a round pipe, a driving device, a rod body and a conveying cavity. The multiple conveying cavities penetrate through the circular pipe, outlets of the conveying cavities are formed in the outer side wall of the circular pipe, the rods are arranged in the conveying cavities in a one-to-one correspondence mode, the driving device is arranged in the circular pipe, and the driving device is matched with the rods to drive one ends of the rods to move out of the circular pipe from the outlets of the conveying cavities. The anti-floating anchor rod has the beneficial effect that the anti-floating force of the anti-floating anchor rod of the underground structure in soft soil is enhanced.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering research, in particular to an anti-floating bolt in soft soil. Background technique [0002] Anti-floating anchor rod is a kind of anti-floating measures for underground structures in construction projects. The anti-floating anchor refers to the structural member set up to resist the upward displacement of the building on it, which is related to the level and change of the groundwater level, and is opposite to the force direction of the compression pile. [0003] When the basement is subjected to excessive groundwater pressure, anti-floating piles, or anti-floating anchors, or decompression and drainage on the ground of the basement are required, while anti-floating anchors are used in soft soil, and there is bonding between the anchor grouting body and the soft soil interface Therefore, it is necessary to enhance the anti-floating performance of the bolt in soft soil.
