Description

Water-intercepting micro-irrigation method for concrete frame slope protection plants

Technical Field

The invention belongs to the field of water and soil conservation, and relates to a slope plant water interception micro-irrigation method for slope protection. In particular to a water-intercepting micro-irrigation method for concrete frame slope protection plants. The method has the advantages of less water and soil loss, simplicity, practicality, long plant survival time, good effect, small environmental protection influence, investment saving, no power equipment, no maintenance, low labor intensity of workers and short construction period.

Background

At present, a large number of concrete frames are used for protecting side slopes in the industries of water conservancy and hydropower, highways, railways, port and navigation traffic, mines and the like, and plants are planted in the frames for greening ecological management. However, in practical use, due to different climates in various regions, some rainfall is abundant, some rainfall is less, concrete frame slope protection plants can not survive easily due to lack of water and drought when the rainfall is less, and the regions with abundant rainfall are easy to cause slope runoff or strong rainwater and high-pressure jet flow maintenance water to wash soil planted in the frames. In the area with less rainfall, the frame is usually in a steep slope, so that moisture is easy to slip away from the slope surface and cannot enter the planting soil to a depth which is most suitable for the growth of plants, and therefore, the method of arranging a concrete frame header on the frame and the micro-irrigation system with electric equipment are generally adopted in engineering to solve the problem. However, the height of the concrete frame head is not large, the slope runoff can not be effectively shunted to two sides and downward throwing flow is easy to form when the concrete frame head is in a square frame, and the scouring effect of water flow on the vegetation soil is intensified. In addition, when rainfall or maintenance water amount is small, moisture on the frame cross beam cannot be utilized to the maximum extent and enters the optimum depth of the planting soil, particularly, the moisture is wasted and polluted when a watering cart is adopted for spraying and fertilizing in the later period, and the electric micro-irrigation system needs power, so that the investment is large and the maintenance is troublesome. Therefore, under the guidance of the policy of vigorously advocating ecological development at present, how to overcome the above defects becomes a problem which needs to be solved urgently at present.

In order to realize the purpose, the following technical scheme is adopted:

a water-intercepting micro-irrigation method for concrete frame slope protection plants comprises the following steps:

step S101, cleaning floating slag and floating slurry of the lower vertical surface of the concrete beam, and performing closed repairing treatment on defective honeycombs, pitted surfaces and loose surfaces of the lower vertical surface of the concrete frame beam to prevent leakage from a defective part;

step S102, polishing and leveling the lower vertical surface of the concrete frame beam and the water stop joint surface of the water intercepting pool or leveling by adopting surface mortar;

step S103, drilling an anchor rod planting hole on the lower vertical surface of the cross beam, wherein the anchor rod planting hole corresponds to the reserved hole of the top baffle plate;

step S104, cleaning the anchor rod installation hole, and then installing the anchor rod by using anchoring mortar or anchoring agent;

step S105, coating belt rubber on the joint surface of the water stop and the water interception pool, installing two sides of rubber water stop and bottom water stop on the inner side of the water interception pool, removing half thickness of the side water stop and the bottom water stop respectively and performing gluing treatment on the overlapped part of the side water stop and the bottom water stop, enabling a water interception plate forming the water interception pool to be vertical to the surface of the cross beam and to be higher than the surface of the cross beam by not less than 20cm, and installing a filter element at the bottom of the water interception plate through a filter element fixing seat;

step S106, after the anchoring mortar reaches the strength of technical specifications of rock-soil anchor rod and shotcrete support engineering (GB 50086-2015), coating sealant on the joint of the water stop and the lower vertical surface of the concrete frame, installing a water interception tank with water stop and keeping the filter element at the depth of 20cm-30cm of the planted soil;

and S107, pressing the intercepting basin by using a nut on the anchor rod, keeping the sealing part watertight, and then locking by using a locking nut.

The anchor rod is made of ribbed threaded steel bars with threads at exposed ends or expansion bolts.

The intercepting pool is made of plastics, and the water stop is made of rubber.

The intercepting pool can be replaced by a flat plate.

The water intercepting pool can be arranged into two water intercepting pools in one sash, and the height of the side coaming of the water intercepting pool, which is close to the ground beam side and is vertical to the cross beam, of the side surface of the water intercepting pool is lower than that of the side coaming of the water intercepting pool positioned in the middle.

Compared with the prior art, the invention has the following beneficial effects:

the invention overcomes the defects of the prior art, discloses a water-intercepting micro-irrigation method for concrete frame slope protection plants, and achieves the following effects:

1. adopt the board of intercepting on the intercepting basin to intercept the runoff effectual, the baffle height can be adjusted according to actual conditions to can effectively let the runoff to both sides reposition of redundant personnel, the effectual abrupt slope runoff of avoiding is to the washing away of planting soil.

2. When the rainwater and the maintenance water amount are small, the rainwater and the maintenance water on the cross beam can be collected to the maximum extent, and the method is particularly favorable for arid areas.

3. The seepage through the filter element can enter the soil to a depth of 20-30 cm which is most suitable for the growth of plants, so that a self-flowing micro-irrigation system is formed, the problem that the moisture on the steep slope surface can not enter the soil by gravity is solved, the moisture supplement time is prolonged, and the growth of the plants is facilitated.

4. The irregular slope rainwater runoff has the washing and cleaning effect on the filter element, so that silting of the seepage channel can be prevented, and meanwhile, part of sundries can be taken away along with the water flow, and silting is prevented.

5. The substances containing more nutrients, such as powder particles, clay particles and the like which are smaller than the equivalent aperture (usually about 0.02 mm) of the filter element can enter the planting soil through the seepage channel of the filter element, thereby being beneficial to the long-term survival of plants and saving fertilizers.

6. Because the ground beam plays the primary role of bank protection in the concrete frame roof beam, the crossbeam only plays the effect of even system and box, plants the stock on the crossbeam, does not have the influence to the function of crossbeam structure, and can accelerate the construction progress.

7. The same angle slope in intercepting pond is installed on the crossbeam, and highly being less than the bounding wall that is located the centre at the bounding wall that leans on the perpendicular to crossbeam of grade beam side, is favorable to debris to be discharged from the bounding wall low level that leans on the grade beam smoothly, is difficult for blockking up simple and practical.

8. The water permeates from the inside to the outside, so that the soil is not easy to harden.

9. When the fertilizer is used for fertilization, the nutrient loss is less, and the fertilizer pollution is less.

10. No power, no maintenance, simple construction and good effect.
