Description
Technical Field
The utility model relates to a land side slope treatment technology, in particular to a side slope reinforcement structure of a freezing pipe network.
Background
The slope management is a disaster prevention project with complex technology and difficult construction. In recent years, with the rapid development of highway construction industry and the increasing of large key engineering projects, slope management is more and more prominent.
The slope reinforcement measures available at present are many, and include a slope cutting and load reducing technology, a drainage and water interception measure, an anchoring measure, a concrete shear-resistant structure measure, a retaining measure, a slope pressing measure, a plant sash slope protection and a surface protection measure, and the like, and the principle of comprehensive treatment of multiple measures is emphasized in the slope treatment engineering so as to strengthen the stability of the slope. However, with the continuous increase of the scale of engineering construction, the height of the side slope is increased, the complexity is increased, the technical requirements on the treatment of the side slope are higher and higher, and the current side slope reinforcement measures can not meet the actual requirements far away.
(1) And (5) grouting reinforcement.
When the slope body of the side slope is broken and the joint crack grows, the pressure grouting method can be adopted to reinforce the slope body of the side slope. Under the action of pressure, grouting liquid permeates to the periphery through joint cracks cut around the wall of a drill hole, and plays a cementing role in the broken slope rock-soil body to form a whole body; in addition, the mortar column plays a role in bolt connection on the broken side slope rock-soil body, and the aim of improving the integrity and stability of the slope body is fulfilled. The grouting reinforcement can be used for deep reinforcement of the side slope.
(2) And (5) reinforcing the anchor rod.
When the slope body of the side slope is broken or the stratum of the side slope is weak, a certain number of anchor rods can be driven in to reinforce the side slope. The mechanism of the anchor rod for reinforcing the side slope is equivalent to the action of the bolt. The anchor rod reinforcement is a middle-shallow layer reinforcement means.
(3) And (5) soil nail reinforcement.
For soft rock side slopes or soil side slopes, a sufficient number of soil nails can be driven into the slope body, and the side slopes are reinforced. The mechanism of soil nailing for reinforcing the slope is similar to the action of the group anchor. Compared with anchor rods, the soil nail reinforcement has the characteristics of short length and dense density, and is a shallow slope reinforcement technology. The two are different in design calculation theory, but are similar in construction process.
(4) And (5) reinforcing the prestressed anchor cable.
When the side slope is higher and the possible potential fracture surface position of the slope body is deeper, the prestressed anchor cable is a better deep reinforcing means.
In the high slope reinforcement project, compared with other reinforcement measures, the prestressed anchor rope has the following characteristics: 1) the stress is reliable. 2) The acting force can be uniformly distributed on the slope to be reinforced, the adaptability to the terrain and geological conditions is strong, and the construction conditions are easy to meet. 3) And (6) actively bearing force. 4) The blasting excavation is not needed, the disturbance and the damage to the slope body are not generated, and the mechanical property of the slope body can be maintained unchanged. 5) The construction speed is high.
Different reinforcing methods are adopted for the side slopes of the soil and rock.
(1) Soil slope: the stability of the soil slope is sensitive to underground water, and particularly under the seepage conditions of high water level and large hydraulic gradient of a slope, the additional slip force and seepage instability generated by the seepage pressure on the slope are often the main reasons of instability of the soil slope. The dredging engineering can effectively eliminate or reduce osmotic pressure on the soil slope, and simultaneously convert saturated soil into unsaturated soil, thereby increasing the strength of the soil, and playing a positive role in improving the stress condition of the slope and increasing the strength of the slope. This method is often used because of its remarkable effect. Soil slope reinforcement can also be applied to anchoring engineering in soil bodies, and external integral retaining facilities such as retaining walls or counter-pressure platforms are also commonly adopted to maintain stability for the soil slopes with low heights.
(2) Rock slope: because the lithology, structure and hydrogeology conditions are complex and the failure modes are different, the adopted reinforcing measures are various and can also be reinforced by comprehensive measures. The strengthening of the sliding body of the large iron ore smelting in China No. 1: the upper part is used for slope cutting, load reduction, guniting protection surface and anchoring of a prestressed anchor rod, and the middle and lower parts are reinforced by comprehensive treatment such as deep-hole anti-slide piles, horizontal hole drainage and the like. The retaining wall used on the rock slope is very few, and when the slope toe is too steep and possibly causes instability, the slope toe is always stabilized by counter-pressure of the platform.
