Description

Technical Field

[0001] The utility model belongs to the technical field of ecological slope protection, in particular to an ecological slope protection for a water conservancy project. Background Art

[0002] Slope protection engineering mainly refers to various paving and planting operations around the slope to prevent the slope from being eroded. Its main function is to resist weathering and erosion, and to a certain extent reduce the bearing pressure of the slope.

[0003] Ecological slope protection is a slope protection technology that integrates basic knowledge of engineering mechanics, soil science, ecology and botany to support slopes or side slopes. By planting plants and utilizing the interaction between plants and rocks and soil (such as root anchoring), the surface of the slope is protected and reinforced, so that it can not only meet the requirements for the stability of the slope surface, but also restore the damaged natural ecological environment. This slope protection method can not only prevent the scouring and erosion of the bank by water flow through the construction of porous and permeable protection structures, but also use plants and natural materials to meet the requirements of bank stability, provide good habitat conditions for aquatic organisms, maintain the ecological functions of natural rivers, and improve the natural landscape. It is an effective means of slope protection and consolidation.

[0004] Traditional ecological slope protection planting holes are set as independent openings, and plants are planted in the planting holes to protect and reinforce the slope. However, on rainy days, water is easily accumulated in the planting holes. The accumulated water will soak the soil in the planting holes for a long time, and the soil will be more moist, which can easily cause soil loss. Utility Model Content

[0005] In order to solve the problem that the planting holes of traditional ecological slope protection are set as independent openings, water is easily accumulated in the planting holes on rainy days, which easily causes soil loss, the utility model provides an ecological slope protection for water conservancy projects.

[0007] An ecological slope protection for a water conservancy project comprises a concrete slab which can be positioned and installed on the upper side of a slope; a plurality of through planting holes are provided on the concrete slab; a longitudinal second drainage groove and a plurality of inclined first drainage grooves are provided on the upper side of the concrete slab, the first drainage grooves are connected to the planting holes and the second drainage grooves, and the planting holes are located at the upper ends of the first drainage grooves.

[0008] A further improvement of the utility model is that the first drainage groove is connected to a side of the planting hole away from the shore.

[0009] A further improvement of the utility model is that the angle between the first drainage grooves is 45-80 degrees.

[0010] A further improvement of the utility model is that the second drainage groove is centrally arranged, and the planting hole and the first drainage groove are arranged symmetrically with respect to the second drainage groove.

[0011] A further improvement of the utility model is that the bottom of the first drainage ditch is 10 mm high from the slope.

[0012] A further improvement of the utility model is that a casting groove is provided at the bottom of the slope; and a plug-in portion matching with the casting groove is provided at the bottom of the concrete slab.

[0013] A further improvement of the utility model is that the second drainage groove extends to the side away from the shore and penetrates the side surface of the concrete slab.

[0014] A further improvement of the utility model is that a plurality of reinforcing ribs which can be positioned and inserted into the slope body are connected to the lower side of the concrete slab.

[0015] A further improvement of the utility model is that a plurality of fixing piles capable of being positioned and inserted into the slope body are connected to the left and right sides of the concrete slab.

[0016] A further improvement of the utility model is that the direction of the reinforcing ribs is the vertical direction, and the fixing piles are perpendicular to the slope surface.

[0017] It can be seen from the above technical solutions that the beneficial effects of the utility model are:

[0018] By planting plants in the slope at the planting hole position, on rainy days, the accumulated water in the planting hole can be diverted to the second drainage groove through the first drainage groove, and then guided to the water at the bottom of the slope through the second drainage groove, thereby preventing the accumulated water from soaking in the planting hole for a long time and preventing soil loss.

[0024] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0025] like Figure 1-3 As shown, the utility model discloses an ecological slope protection for a water conservancy project, comprising a concrete slab 2 which can be positioned and installed on the upper side of a slope 1; a plurality of planting holes 3 (circular, square, or other shapes) which pass through from top to bottom are provided on the concrete slab 2; a longitudinal second drainage groove 5 (downward along the surface of the slope 1) and a plurality of inclined first drainage grooves 4 are provided on the upper surface of the concrete slab 2, the first drainage groove 4 connects the planting hole 3 and the second drainage groove 5, and the planting hole 3 is located at the upper end of the first drainage groove 4.

[0026] By planting plants in the slope 1 at the planting hole 3, on rainy days, the accumulated water in the planting hole 3 can be guided to the second drainage groove 5 through the first drainage groove 4, and then guided to the water at the bottom of the slope 1 through the second drainage groove 5, thereby preventing the accumulated water from being immersed in the planting hole 3 for a long time and preventing soil loss. The overall structure is simple, easy to implement, and has good practicality.

[0027] The first drainage groove 4 is connected to the side of the planting hole 3 away from the shore, so as to better guide the accumulated water.

[0028] The angle between the first drainage groove 4 and the second drainage groove 5 is 45-80 degrees. According to the inclination angle of the slope 1, the angle between the first drainage groove 4 and the second drainage groove 5 is designed to ensure that the drainage speed of the accumulated water is moderate, which can not only ensure the timely drainage of the accumulated water, but also avoid soil loss. The second drainage groove 5 can be set to a different angle from the second drainage groove 5 according to the arrangement position of the planting hole 3.

[0029] Among them, the second drainage groove 5 is arranged in the center, and the planting hole 3 and the first drainage groove 4 are arranged symmetrically with respect to the second drainage groove 5. The symmetrical arrangement has good aesthetics, and the drainage is symmetrical and balanced on the left and right.

[0030] The bottom of the first drainage ditch 4 is 10 mm away from the slope 1, which can ensure the drainage of most of the accumulated water and prevent the soil from being lost with the accumulated water.

[0031] A horizontal casting groove 8 is provided at the bottom of the slope 1, and a plug-in portion that fits the casting groove 8 is provided at the bottom of the concrete slab 2, so as to facilitate the pouring construction of the concrete slab 2 and realize the reliability of positioning the concrete slab 2 and the slope 1.

[0032] The second drainage ditch 5 extends away from the shore and penetrates the side of the concrete slab 2 , so that the accumulated water can be directly drained to the lower water, avoiding water accumulation at the lower end of the second drainage ditch 5 .

[0033] Among them, a plurality of reinforcing ribs 6 that can be positioned and inserted into the slope 1 are connected to the middle of the lower side of the concrete slab 2, and the direction of the reinforcing ribs 6 is the vertical direction. A plurality of fixing piles 7 that can be positioned and inserted into the slope 1 are connected to the left and right sides of the concrete slab 2 at intervals in the direction away from the shore, and the fixing piles 7 are perpendicular to the surface of the slope 1. The reliability of the concrete slab 2 wrapping can be ensured by positioning the reinforcing ribs 6 and the fixing piles 7 with the slope 1. The reinforcing ribs 6 and the fixing piles 7 have a certain angle to enhance the reliability of the connection with the slope 1.

[0034] The concrete slab 2 is constructed by integral pouring. Now, a pouring trough 8 is opened at the bottom of the slope 1 to support the formwork, and fixed piles 7 and reinforcing ribs 6 are pre-buried in the slope 1. Concrete is poured from top to bottom. After solidification, the formwork is removed to form the ecological slope protection. The construction is convenient and easy to implement.

[0035] The ecological slope protection of the water conservancy project is to plant plants in the slope 1 at the planting hole 3. On rainy days, the accumulated water in the planting hole 3 can be diverted to the second drainage groove 5 through the first drainage groove 4, and then guided to the water at the bottom of the slope 1 through the second drainage groove 5, thereby preventing the accumulated water from being immersed in the planting hole 3 for a long time and preventing soil loss. The overall structure is simple, easy to implement, and has good practicality.
