Description

Square grid type organic material slope protection structure

Technical Field

The utility model relates to the technical field of slope protection construction of side slopes, in particular to a square grid type organic material slope protection structure.

Background

The existing slope protection mainly adopts engineering measures for protection, and comprises slope protection and retaining structure protection. Common protection measures (methods) for the slope surface comprise plastering, guniting, concrete spraying, grouted stone retaining walls, anchor-sprayed slope protection, anchor-sprayed net slope protection and the like by adopting mortar or three-layer soil and the like, and are mainly used for preventing the phenomena of weathering spalling, breaking, small quantity of falling stones, chipping and the like of the excavated slope surface; the types of a retaining structure protection are more, and the retaining structure protection comprises protection measures such as a retaining wall, an anchor rod retaining wall and an anti-slide pile, has a protection effect and also has a slope body reinforcing effect. However, no matter which kind of engineering measures are adopted for protection, the defects of damage to ecological nature, poor landscape effect and the like exist, and the concrete surface and the mortar sheet stone surface can be weathered, aged and even damaged along with the passage of time, so that the later-period treatment cost is higher.

Aiming at the defects of engineering measure protection, plant community protection is increasingly applied, but the functions of plant community slope fixation and soil maintenance are limited in space and time, on one hand, the plant community cannot relate to the collapse of deep soil or the sliding of an extremely thick soil layer, and on the other hand, the plant community can hardly reach the deep soil layer in a short time due to the fact that the plant community needs a long time for growing.

Under the working condition of a high and steep slope, the problems that a substrate for supplying plants to grow is difficult to attach to the slope and the plants cannot grow exist, in the existing slope protection technology, an anchor rod is usually fixed in the slope range, a frame beam is poured, and a flexible net mainly comprising a steel wire rope net is covered and wrapped on the surface of the whole slope range, so that the reinforcement effect is achieved, the weathering spalling or damage and dangerous rock collapse of the rock mass of the slope are limited, and meanwhile, the rockfall enclosure is controlled within a certain range. However, such a conventional slope protection structure has two main problems: on one hand, the poured frame beam forms visible slope masonry, which affects the greening and landscape effects of the slope; on the other hand, the lattice beam divides the surface soil body of the side slope into a plurality of independent unit soil blocks, and after vegetation protection is adopted, each unit soil block is isolated from each other, so that an integral protective layer structure is difficult to form, and the integral protective effect is poor.

Therefore, how to design the slope protection structure can ensure the stability of the high and steep slope in a short-term and long-term time range becomes a technical problem of intensive research of high and steep slope protection engineering technicians. The high and steep slope protection relationship solves the contradiction between slope engineering protection and ecological environment destruction, and is also an important subject for realizing harmony and coexistence of human activities and natural environment.

It is worth to point out that: when the drainage channel 10 is manufactured, the lattice beam pouring template is installed in advance, the lattice beam pouring template comprises a lattice beam main structure template and a drainage channel template, slurry leakage treatment is carried out on the intersection position of the lattice beam pouring template and the slope protection net, the slurry leakage treatment comprises installation of a sealing strip or filling of a foaming agent, for example, a foam sealing strip is added in a plugging mode or a polyurethane foam gap filler is added in the filling process, and therefore the slurry leakage problem of the lattice beam in the pouring process is avoided or reduced. The lattice beam has the main function of integrally connecting the side slope structures to fulfill the aim of reinforcing the side slope, so that the pouring construction requirement of the lattice beam is not high, and the reinforcing function of the lattice beam is not influenced by slight slurry leakage.

The foregoing is merely a detailed description of specific embodiments of the utility model and is not intended to limit the utility model. Various alterations, modifications and improvements will occur to those skilled in the art without departing from the spirit and scope of the utility model.
