Description

Concrete grid ridge filling dry block stone ecological landscape slope protection

technical field

The utility model relates to a slope protection structure, which belongs to the ecological regulation technology of river and lake bank slopes, in particular to an ecological landscape slope protection filled with concrete lattice ridges and dry block stones.

Background technique

Ecological slope protection is a slope protection technology that integrates the basic knowledge of engineering mechanics, soil science, ecology and botany to support slopes or side slopes and form a comprehensive slope protection system composed of plants or engineering and plants. After the excavation slope is formed, by planting plants, the interaction between plants and rock and soil (root system anchorage) is used to protect and reinforce the surface of the slope, so that it can not only meet the requirements for the stability of the slope surface, but also can The slope protection method to restore the destroyed natural ecological environment is an effective means of slope protection and slope consolidation.

The emergence of slope protection technology comes from the long-term struggle between human beings and floods. In ancient times, embankments against floods often collapsed due to water erosion. With the gradual development of slope protection technology, the gravity retaining wall built with block stones played an important role in the early human struggle against floods.

The application of concrete technology has greatly promoted the development of slope protection technology, and masonry slope protection, cantilever retaining wall, anchor shotcrete support and other methods have emerged as the times require. These traditional slope protection types have improved slope stability and are of great help to improving slope safety protection, Soil erosion plays a significant role. So far, it has been widely used in water conservancy, roads, construction, municipal gardens and mining and other fields.

With the application of traditional concrete river slope protection types, its disadvantages have become more and more obvious. Traditional slope protection seals the surface of the entire river slope and isolates the material exchange between the soil and the water body. Plants on the original river bank slope cannot grow, which in turn affects the virtuous cycle of aquatic animals and plants and the entire water ecosystem. Water quality deteriorates, bacteria Ecological and environmental problems such as breeding and extinction of aquatic animals and plants need to be changed urgently.

With the development of economy and society and the improvement of people's living standards, the desire to improve life and get close to nature is becoming more and more urgent. Based on this, an ecological slope protection technology concept integrating engineering mechanics, soil science, ecology and botany has been widely recognized. Ecological slope protection technology aims to restore the balance of the river ecosystem while satisfying the function of river slope protection, bring green into life, and integrate life into nature.

The development of the above-mentioned slope protection technology shows that the original slope protection method has little effect and cannot meet the safety requirements of the structure; although the traditional slope protection technology has improved the safety of slope protection, the ensuing damage to the water environment has seriously affected people's lives. The concept of new ecological slope protection integrates structural safety and ecological improvement, and can effectively improve the status quo of water pollution. It is the frontier direction of the development of river slope protection technology. It is urgent to study new types and new structures of ecological landscape slope protection technology.

For this reason, the applicant has conducted useful explorations and attempts, and has found a solution to the above-mentioned problems, and the technical solutions to be introduced below are produced under this background.

detailed description

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

Referring to Fig. 1 and Fig. 2, the figure shows the ecological landscape slope protection with concrete lattice ridge filled with dry blocks, including a slope top 100, a slope surface 200 and a slope foot 300.

Concrete lattice ridges 210 are arranged on the slope 200 below the design flood level, and a plurality of lattice ridge frames (not shown) are formed on the concrete lattice ridge 210, and each lattice ridge frame is filled with The dry block stone 220 is laid with a layer of geotextile 230 below the concrete grid ridge 210 .

The concrete strength grade of the concrete grid 210 is generally not lower than C20, the size is 400mm×600mm, and the grid spacing is 3-4m, which can form a stabilizing effect on the dry block stone slope. The slope ratio is determined according to the overall stability calculation. In terms of plane layout, the concrete lattice ridge is in the shape of a plane grid, and its shape is flexible and varied. Various beautification patterns can be set up to enrich the riverside landscape effect.

It is necessary to ensure that the volume of each block of the dry block 220 is large enough, and the weight of the block itself can effectively resist the erosion of water at a relatively high velocity. According to the requirements of clause D.3.4 in the "Code for Design of Embankment Engineering" (GB 50286-2013), the thickness of slope protection works under the action of water flow can be calculated according to the following formula:

In the formula: d--thickness of slope protection (m);

V--water velocity (m/s);

g - acceleration of gravity (m/s ² );

C--stability coefficient of movement of protective block stone; horizontal bottom slope C=1.2, inclined bottom slope C=0.9;

r _s -- the bulk density of the stone (kN/m ³ );

r—the bulk density of water (kN/m ³ );

According to engineering practice, the allowable non-scouring flow velocity of single-layer dry block stone (20-30cm thick) is 2.50-4.00m/s, and the thickness of block stone is determined according to calculation in specific projects. Ground organic soil is filled in the gaps of dry block stones 220 in each grid frame of the concrete grid 210, and plant seeds are sown on the surface organic soil. In addition, each grid frame of the concrete grid 210 A bagged gravel 240 is embedded at the bottom of the dry masonry stone 220. The bagged gravel 240 is mixed with an appropriate amount of plant rhizomes and organic soil, so that the dry masonry slope can be effectively regenerated and created suitable for aquatic animals, plants and microorganisms. ecological environment. The design of the dry block stone 220 effectively reinforces the concrete lattice ridge 210, so that the integrity of the entire dry stone slope protection is better and the anti-scourability is stronger.

The slope foot 300 is provided with a poured block stone foot 310 extending laterally along the slope surface 200. The stability of the uphill structure is maintained by the weight of the poured stone block 310. The size of the poured stone block 310 is designed by the specific project. Determine, for example, for a slope protection with a slope ratio of 1:2 and a height of 5m, the foot 310 of the poured block stone should be set to 800mm×1000mm.

On the side of the town foot 310 of pouring block stone, ecological gabion foot protection and beach protection 320 are laid. The length L is determined by cutting down the river bed to the calculated maximum scour depth while the slope naturally stops, that is, using the principles of flexibility, ductility and durability of the ecological gabion to form a beach protection near the foot of the slope. Ecological gabion, foot protection and beach protection 320's mesh cage is filled with boulders, dog's head stones, block stone processing residues and other construction auxiliary materials, and the particle size is generally larger than the mesh aperture of the mesh cage. The gaps between the stones of the ecological gabion foot protection and beach protection 320 are filled with organic soil, and the seeds of submerged plants are sown on the organic soil to form submerged plant belts and anti-scour belts in the later stage, which are relatively safe in terms of structure and ecological landscape. it is good.

In addition, green plants are planted at the positions where the slope top 100 and/or the slope 200 are above the design flood level. The greening plants are mainly dwarf shrubs, interspersed with landscape stones, which can beautify the landscape and prevent soil erosion.
