Before using the product, we generally need to check the product, and the hollow grouting anchor must also be checked before use, so how should we check it? The following editor will give you a brief introduction.

The hollow grouting anchor rod is confirmed according to the orientation of the locating grouting ring and grouting ring, and the damaged parts should be replaced in accordance with the technical requirements. Please confirm the direction and smoothness of the exhaust pipe. When the positioning anti-slurry ring reaches the orifice, stop pushing, install the fueling pipe and the one-way valve. After the anchor cable reaches the position, check whether the exhaust pipe is unblocked. If it does not work, pull out the anchor and start sending the cable from the beginning after the problem is solved.

At the same time, the temperature value of the buried point can be measured. If the strong bolt head is in the hole, the cement paper blocking the hole can be lifted, and then the rod body can be inserted and installed in place. If there is no overflow of cement mortar in the hole, it means that the mortar injection is insufficient, and the hollow grouting anchor must be injected from the beginning and then reinstalled. The degree of drilling of the bolt body shall not be less than the design regulations.

The fullness of hollow grouting bolt grouting is the key to ensuring the quality of installation. This process should be inserted into the grouting pipe 5 ~ 10 cm from the bottom of the hole, with the injection of mortar, slowly pull out at a certain speed. When the mortar is insufficient, the mortar needs to be refilled. This is to ensure that the full length of the anchor rod is wrapped in sufficient mortar to act as an anchor.

When the internal attack stress of the structure changes, the hollow grouting anchor rod will be stretched or compressed, and the steel sleeve will deform at the same time. The deformation will make the fixed bolt stress gauge feel stretched or compressed. The deformation is transferred to the vibrating string, and converted into a change in the stress of the vibrating string, and then the vibration frequency of the vibrating string is changed.

The electromagnetic coil excites the vibrating string and measures the vibration frequency. The frequency signal is sent to the reading device through the cable, which can measure the stress of the steel bars in the measurement structure.
