Description
Technical Field
The invention belongs to the field of slope ecological protection, and particularly provides a method for treating a local sunken part in a rock steep slope ecological restoration project, so that the aim of reducing or even eliminating the negative influence of the sunken part on the ecological restoration project is fulfilled when the rock steep slope is subjected to ecological protection.
Background
With the continuous development of the basic construction of China, the projects of highway, railway water conservancy and the like are increased continuously, the projects are large in scale and wide in related range, and a large amount of exposed earth and stone slopes formed in earth and stone excavating and filling projects destroy the existing vegetation and damage the local ecological balance. Therefore, ecological protection is required for the side slope. However, when ecological protection is performed on a rock slope, local slope surface sinking is often encountered. The upper part of the pits is a reverse slope on which plants are difficult to grow; not only influences the stability of ecological restoration measures to a certain extent, but also greatly influences the attractiveness. At present, two methods of excavation and filling with cement mortar are mainly used for the sunken part in engineering. Although the two measures can eliminate the influence of the depression on the ecological restoration engineering, the cement mortar has high density, and is easy to cause large secondary loading on a slope body at the lower part of the depression to influence the stability of the slope; the cement mortar is used for completely filling, so that the consumed materials are too much, the cost is high, and the environment is not protected; although the excavation method is simple, the excavation method is not suitable for the side slope with better rock quality, the construction work amount is too large, and the difficulty is relatively high, so that a treatment method which can meet the ecological protection requirement and is convenient to construct is required to be found to solve the problem.
Disclosure of Invention
The invention aims to provide a method for treating a local sunken part in ecological restoration engineering of a rocky steep slope. So as to achieve the purpose of reducing or even eliminating the negative influence of the depression on the ecological restoration engineering at lower cost and lighter weight.
In order to achieve the technical features, the invention is realized as follows: a processing structure for a local sunken part in the ecological restoration process of a rocky slope comprises a supporting framework fixed inside a slope sunken part, other spaces in the sunken part are filled with foaming glue except the supporting framework, the surface of the sunken part is cut into a transverse zigzag outline after the foaming glue is solidified, a concrete canvas is paved on the transverse zigzag outline, and a vegetation base material can be paved on the concrete canvas after the concrete canvas is watered and solidified.
The supporting framework is formed by splicing a plurality of wooden cross rods, longitudinal rods and vertical rods with rectangular cross sections and side lengths of 2-4 cm through long nails, and the length and the distance of each rod are adjusted through the size of a recess.
The foaming adhesive is a low-shrinkage polyurethane product, the profile of a transverse sawtooth on the surface of the foaming adhesive is not more than 4cm in undulation, and the span of a single sawtooth is 8 cm-10 cm.
The width of the concrete canvas is not less than 1.6m, the length of the concrete canvas is not less than 5m, and the concrete canvas is tightly attached to the hardened foaming adhesive and the peripheral surface of the recess when the concrete canvas is laid.
The method for processing the processing structure of the local depressed part in the ecological restoration process of the rocky slope comprises the following steps:
the method comprises the following steps: cleaning the concave surface of the side slope and measuring the size;
step two: manufacturing a corresponding supporting framework according to the measured size;
step three: placing the supporting framework into the recess and fixing;
step four: spraying foaming glue until a small amount of foaming glue overflows, and cutting a transverse sawtooth-shaped profile on the surface after the foaming glue is solidified;
step five: paving concrete canvas on the surface of the filled slope body, and watering and solidifying;
step six: and laying a plant growth substrate for ecological protection.
The invention has the following beneficial effects:
1. the wood supporting framework and the foaming adhesive are both light materials, so that secondary loading which can affect the stability of the side slope is not caused after construction;
2. the concrete canvas has good flexibility when not watered, can be easily attached to the surface and the periphery of the filled depression, and can better link the filling structure with the slope body around the depression after being watered and hardened.
3. The sawtoothed surface of the foamed rubber after being condensed improves the bending resistance of the concrete canvas, so that the concrete canvas can bear more load from upper ecological protection measures, and the service life is prolonged; and secondly, the problems of slipping of the plant growth substrate along with the time can be reduced.
4. The structure has the advantages of simple construction process, low cost, small occupied construction site, popularity and wide application value.

Example 1:
referring to fig. 1-3, a method for treating a local sunken part in ecological restoration engineering of a rocky steep slope comprises a wood supporting framework fixed in a slope sunken part, wherein low-shrinkage hard foaming glue is filled around the supporting framework; and cutting saw-tooth-shaped gullies on the surface of the foamed rubber after the foamed rubber is solidified, and paving the concrete canvas. By utilizing the combination method, the ecological protection measures can be ensured to normally play a role in the side slope depressions, and the problem that the plant growth base materials slide down along with the increase of time is reduced to a certain extent.
Furthermore, the supporting framework is formed by splicing a plurality of wooden cross rods, longitudinal rods and vertical rods with rectangular cross sections and side lengths of about 2-4 cm through long nails, the length and the distance of each rod can be adjusted through the size of the recess, and the most environment-friendly use effect can be achieved through the structural size.
Furthermore, the foaming adhesive is a low-shrinkage polyurethane product, so that a light effect is achieved under the condition of sufficiently bearing the load of the plant growing base material, and a stable secondary load which is sufficiently influenced on a slope body at the lower part of the depression can not be generated.
Furthermore, the fluctuation of the transverse sawtooth profile on the surface of the foaming adhesive is not more than 4cm, and the span of a single sawtooth is 8 cm-10 cm. Can improve concrete canvas's bearing capacity when guaranteeing the normal growth of plant through above-mentioned structure, reduce the growth of vegetation substrate along with time simultaneously and produce the problem of landing.
