Anchor rod supporting body base body, anchor rod supporting body and method for manufacturing anchor rod supporting body

Abstract

The invention provides an anchor rod supporting body base body, an anchor rod supporting body and a method for manufacturing the anchor rod supporting body. The anchor rod supporting body comprises a front end base, a rear end base and a capsular bag. Threading tubes are connected between the front end base and the rear end base. The two ends of the capsular bag are used for being connected with the front end base and the rear end base in a sealed mode to define a hollow cavity together with the front end base and the rear end base. The rear end base is further provided with a grouting pipe used for injecting slurry into the hollow cavity. Elastic buffer material layers which can be squeezed to form elastic sealing layers after the capsular bag is bundled onto the front end base and the rear end base are wound on the outer circumferential face of the front end base and the outer circumferential face of the rear end base. In this way, due to the facts that the elastic buffer material layers are wound on the outer circumferential face of the front end base and the outer circumferential face of the rear end base and can form the elastic sealing layers after the capsular bag is bundled, a better sealing effect between the capsular bag and the front end base as well as between the capsular bag and the rear end base can be guaranteed. Compared with an existing mode that a capsular bag and rigid end bases are directly bundled together, sealing is made more reliable.

Description

technical field [0001] The invention relates to a base body of an anchor rod bearing body, an anchor rod bearing body and a manufacturing method of the anchor rod bearing body. Background technique [0002] There are different amounts of soft soil distributed throughout our country. The silty clay in it has the characteristics of low strength, high compressibility, and long solidification period. If anchor rods are directly used for foundation pit support, the hole wall may easily collapse after the hole is formed. , The controllability of grouting is poor, and the designed uplift bearing capacity is often not reached, and the construction quality is difficult to guarantee. [0003] In response to such problems, the Chinese utility model patent with the application number 201320662173.0 and the authorized announcement date of 2014.04.02 discloses a high-pressure pendulum spray follow-up bag-expanding bolt carrier, which includes front and rear The end seat and the cloth bag...

However, it is difficult to tie the pouch directly on the metal end seat in this way. Even if the binding is reliable, the mating surface of the pouch and the metal end seat cannot be well sealed and often leaks easily, and the mouth of the pouch Larger, the bladder tends to be folded with many folds when strapped to the end seat, and these folds often leak
