There are many technical points in the construction of engineering buildings, which need to be completed in accordance with the technical points to ensure the quality of the engineering building. Hollow anchors also have many technical points in the construction. Here is a brief introduction to the technical points of the hollow anchor during construction.

1 , hollow bolt technical layout elements:

Engineering construction workers are generally arranged radially according to the tunnel construction section, with a large viewing angle from the main rock structure. If the main structure surface is not obvious, the construction professional and technical personnel can arrange the dot matrix laser with red plum-shaped anchor rods on the excavation surface of the foundation pit according to the vertical arrangement of the porch near the tunnel construction.

2 , hollow bolt hole portion:

The deviation is usually no more than 4 ~ 10 cm. After drilling the hole, the constructor must rinse it with water, and then blow out the moisture inside to make it volatilize. To mechanically anchor the bolt hole, the deviation of the hole depth must be operated between -1 and 1cm. When the professional and technical personnel go deep into the design plan, when encountering broken geotechnical engineering partitions or relatively soft rock formations, they must change the hollow bolt Location and depth.

3 , hollow bolt supporting the whole construction process:

Professional technicians should ensure that the hollow anchor rod is not damaged, not stained with oil powder and residue, and not rusted. Otherwise it will seriously endanger the overall quality of the project. The wedge seam anchor rod must ensure that the wedge seam is flat and vertical, and the position is located on the cross section of the bolt management center. The joint width deviation must be in the middle of ±0.5mm, and the joint length deviation must be operated within ±5mm.

4 , a hollow bolt installation technical criteria:

For building reinforced concrete mortar anchor rods, generally grouting first, then steel anchoring and grouting, two types of construction processing technology, use the construction method of grouting first and then steel anchoring. When installing, pay attention to the quality of running mortar products. When using the post-anchor grouting construction method, it is necessary to pay attention to the difficulty of grouting the exhaust pipe, otherwise the non-round plaster will easily cause the actual effect of steel anchoring to be poor.
