4 Methods to Reinforce the Slope, Self-drilling Anchor Bolt Is the Best One
Time:2022-02-17From:sinorock View:
The slope is a very common terrain in highway and railway construction. During the construction process, it needs to be reinforced and supported by various methods to prevent collapse, falling rocks, uneven slope stress distribution, etc., and reduce safety. hidden danger. There are many methods for slope support. Today, Sinorock will introduce and analyze the advantages and disadvantages of the following four common slope support ways in detail.Supporting the slope by the self-gravity of the retaining wall
Gravity retaining wall slope support is a relatively traditional and common slope support method. Its principle is to use the gravity of the slope body or the wall itself to resist the side pressure of the slope. Gravity retaining walls can be made of concrete, block stone, rubble, etc. Masonry or concrete can be directly poured on the slope surface, and are often used in highways, harbors, railways, mines, and other projects.
Advantages: easy to obtain materials and construction, low cost.
Disadvantages: large volume and weight, and it is difficult for weak geology to bear its weight.
Applicable situation: the height of the slope is not large, and the materials can be obtained locally.
Slope Support with Thin Wall Reinforced Concrete
That is, the thin-walled retaining wall belongs to the light retaining wall, which is divided into buttress type and cantilever type.
Advantages: simple structure, convenient construction, lightweight.
Disadvantages: It needs to consume a certain amount of steel and cement. If the slope height is relatively large, the amount of steel will be doubled and the cost will be higher.
Applicable situation: small slope height.
Ordinary bolt support (bolt shotcrete support)
Slope shotcrete support is a support method in which concrete and ordinary hollow bolts are combined to bear the slope weight together with the surrounding rock of the slope. Shotcrete support is a more complicated support method, and the construction process is also more complicated. Shotcrete anchor support is to drill holes on the slope first, then insert the bolts, and then use high pressure to drive the cement slurry into the drilled holes through the bolts to reinforce the surrounding rock mass together with the bolts. Although this support method can effectively limit the deformation of the surrounding rock, adjust the stress distribution of the rock mass, and prevent the rock mass from collapsing and falling, the construction process is too complicated and the efficiency is extremely low.
Advantages: strong adhesion, strong penetration, firm and reliable support.
Disadvantages: The construction process is complicated, the construction is difficult, and the efficiency is low.
Applicable situation: It can be used for temporary support of engineering slope.
Self-drilling anchor bolt for slope support
The self-drilling anchor bolt slope support is similar to the shotcrete support, but the efficiency is much higher than that of the shotcrete support. Most ordinary hollow bolts need to be drilled with drill pipes first, then the bolts are inserted, and then connected with the grouting machine for grouting. The self-drilling anchor bolts themselves are both drill pipes and bolts. After the rotary grouting adapter is connected to the grouting machine, grouting can be performed at the same time as drilling, realizing the integration of drilling, grouting, and anchoring functions, simplifying the construction process and shortening the construction time.
Advantages: convenient construction, strong anchoring force, and high efficiency.
Disadvantages: It is necessary to use a special drilling rig for self-drilling bolts for construction. There are few domestic manufacturers of self-drilling bolts, and there are also fewer self-drilling bolting rigs.
Applicable situation: It is suitable for soft to medium-hard rock formations, especially suitable for soft rock formations, easy to collapse holes, and difficult to form holes.

- 5 common quality problems in construction of self-drilling hollow bolt (SDA system)
- Time:2024-07-30From:This Site
- As a very effective support method, self-drilling hollow anchors have been widely used in rock and soil anchor support system in recent years. Self-drilling hollow anchors not only maintains the stability of soil and rock mass during construction, but also plays an important role as a part of permanent support structure after construction, so it is very important to ensure the construction quality of self-drilling hollow bolt.
